Vuong Hoang aa61fcf5fd test(probe): teach the layout probe about <details>, and guard the flag parser
THE PROBE. A control inside a CLOSED <details> is laid out but sits
outside its collapsed parent's box, so elementFromPoint at its centre
returns an ancestor and it reports OCCLUDED — 23 of them on sindra-set,
every one a false positive. Verified both ways before believing it:
closed, elementFromPoint returns div.gallery; opened, the button itself,
and a real trial click lands on it.

Opening every <details> rather than skipping them is the deliberate
choice. Skipping would make the probe quiet by declaring put-away
controls out of scope, and the add-note button inside
details.item-addnote is exactly the class of control this instrument
exists to check. Fourth false-positive class this probe has grown a
guard for; the other three are already in its header.

THE FLAG PARSER. Three cases that silently break and are cheap to
pin: the flags on either side of the glob (a session should not have to
remember which), a why carrying quotes, an em-dash, a newline and
non-ASCII, and --why with no value after it, which must produce usage
rather than eating the booth name and creating a booth called nothing.

313 tests.

Vuong Hoang 75dca53483 docs(probe): the probe covers the index only, and says so now
The docstring claimed a no-argument run probes 'the booth index and
every booth linked from it'. main() probes argv[1:] or the default URL
and follows nothing — so a coverage claim that reads as 26 pages has
always been one. A probe that overstates its reach is worse than one
that states a small reach honestly, because this is the instrument
standing in for a class of bug the test suite structurally cannot see.

Also records the zsh trap that hid it: an unquoted $URLS holding twelve
space-separated URLs arrives as ONE argument, and the probe cheerfully
reports '2 page(s)' while covering two.

Vuong Hoang a48ef83ef5 feat(manifest): U5 — booths that say who posted them and why
The index card showed a name, an item count and a countdown, and nothing
the poster chose. An agent with something to show therefore had no way to
make the booth say "look at this" and posted a URL to the link board
instead — which is why 145 of that board's 210 rows (69%) ended up
pointing at booths that had already been swept. The board was absorbing a
job it was never shaped for. This is the shape.

Each booth carries `.booth.json` — {handle, title, why, created} — written
by the CLI from $ALTHING_HANDLE, and the provenance line renders on both
index lanes and on the booth page header.

WHAT IS WHERE

- booth/manifest.py, stdlib-only and importing nothing from booth.* either:
  scripts/booth imports it under the system python3 with no venv, and a
  cross-import between two stdlib-only modules is a second way for that
  invariant to break. It joins the shared test_stdlib_only list and keeps
  a stricter copy of its own.
- The read is lenient and cannot raise. list_booths touches every booth on
  every index load, so a manifest that cannot be parsed costs that booth's
  provenance and nothing else. That is the v0.2.2 lesson applied before the
  same mistake rather than after it.
- Absent and damaged render differently — `unannounced` and `unreadable`.
  Folding "cannot be read" into "never said" would hide the one case
  somebody has to go and fix.
- Re-announcing preserves `created`. A second `booth add` sharpening the
  why is not a second appearance of the booth.
- The write is atomic (invariant 5); the temp file is itself a dotfile, so
  no listing can see it mid-write.

THREE OPERATOR CALLS, 2026-09-22

Flags on the existing new/add verbs rather than a separate `announce` verb
(a second step is the step that gets forgotten, which is the rot's own
mechanism). Unannounced booths get a quiet marker rather than nothing — the
convention is only adoptable if the gap is visible. U5 adds provenance only
and does NOT add a second index ordering keyed on announcement time; that
is a different surface needing its own stated rule, parked for v1.1.

NO EXEMPTION LIST

A pickup booth and the standing link board are created by the service, so
they announce themselves with handle `booth`, which is true rather than
manufactured. One rule — a booth with no manifest is unannounced — instead
of a growing set of special cases.

ALSO

tests/test_booth.py's keep/release assertion was slicing the page on the
bare word `boothhead`, which has lived in the stylesheet far longer than
the assertion has; it was reading CSS and passing on luck, and went red the
first time a new rule landed above the old one. Same assertion, aimed at
the markup. A U5 test had the mirror-image bug: pytest derives tmp_path
from the test name and the index renders data_dir, so a test named
`test_an_unannounced_booth_says_so` put the needle in the haystack itself
and passed against a template that did not yet exist.

310 tests (304 before this unit's CLI half). Live service restarted, 26/26
booth pages verified 200, end-to-end smoke through the real CLI.

NOT TAGGED. The cold contract-review panel is still in flight and the
code-review and bug-hunt gates have not run. Tagging with a gate
outstanding is what made v0.2.0 premature.
2026-09-22 00:48:41 -07:00
Vuong Hoang 026a1fc392 fix(marks): v0.2.2 — nine findings from the cross-frontier bug-hunt panel
`/heid-bug-hunt` on U2's diff, four arms, artifact-only. Eight findings were
real against live code; a ninth was already closed by v0.2.1 and is recorded as
declined. Full triage in persistent-memory.d/2026-09-22-bug-hunt-panel.md.

THE LOCK LIFECYCLE (4/4 convergent, and two defects in one place)

`_Locked.__exit__` unlinked `.marks.lock` on the no-op path so a booth that had
never been marked was left exactly as it was found. `flock` binds to an INODE:
unlinking it under a blocked waiter leaves that waiter holding an exclusive
lock on a deleted file while the next writer creates a fresh lock and takes it
immediately. Two processes then run the read-modify-write concurrently, the
later os.replace drops the earlier one's mark, and both obeyed the protocol.

The cleanup existed to protect the booth's TTL, and was failing at that too:
creating or removing a directory entry bumps the DIRECTORY's mtime, which is
what `_newest_mtime` seeds from. The guard's comment reasons about the lock
file's own mtime and misses that the directory moved underneath it.

One fix: never unlink the lock, exempt `.<name>.lock` dotfiles from
`_newest_mtime`, and restore the directory's mtime after creating one.

THE READ PATH'S BLAST RADIUS

`_clean_text` did `(text or "").replace(...)` and `marks_for` sorts on
`(created, id)`, so a stored `text` that was a dict or a `created` that was a
number raised out of the read path. `list_booths` reads every booth's marks on
every index load, so one hand-edited file returned 500 for `/` and `/healthz`
across all 25 booths. Guarded in two layers — a named type check and a
`_hydrate_safe` backstop that cannot raise — and an unreadable mark now renders
as ⚠ broken rather than as an empty note.

ALSO

- import_legacy_asks stamped `created` at whole-second resolution, so two
  sidecars from the same second lost the ordering the importer had just
  established and re-sorted alphabetically. Microseconds, per the stated
  `(mtime, name)` rule.
- The five mark-write routes ran a blocking flock on the event loop; they now
  dispatch through run_in_threadpool, asserted structurally like INV-1.
- `/answer` 500'd on a non-string `notes` form value where `/note` handled it.
- The inline-doc tile had a flag control and no note field.
- The marks panel was suppressed on any booth carrying a links.md.
- The viewer's arrow keys and Escape threw away a note being typed.

CLI

`booth marks` printed a traceback and exited 0 on a failed read, and `--wait`
emitted a whole JSON document per poll. `booth answer --wait` read a damaged
file as "not yet" and spun the full hour. Both now use real exit codes —
0 ok, 1 unanswered/timed-out, 2 no such pick, 3 unreadable — and `--wait`
prints once. `marks.read_error()` lets the CLI ask what the page must not: the
browser stays lenient, the machine consumer gets the truth.

`scripts/booth` had no tests; it has five now, run against the real script
under the system python3, which also makes them a live check on INV-1.

275 tests (253 before). Live service restarted, 25/25 booth pages verified 200.

vh a0448bdc24 fix(booth): list the deprecated asks alias in the usage string
Reported by draupnir. The v0.2.0 note told consumers the alias survives, and the
usage line is exactly where a session checks that claim — a deprecated-but-live
verb that is invisible at its own discovery surface reads as removed.

vh 5e41108cd3 fix(marks): a write over a damaged mark file was wiping the booth's judgment
Three defects and a missing test, all surfaced by the cross-frontier contract
panel dispatched before implementation and triaged after it (heid, four arms,
artifact-only, thread 01M33VSNFER4N1554G0Y0VC9C8). v0.2.0 was already tagged and
announced to fifteen handles when they landed, which is the argument for running
the gate at all.

DATA LOSS. `marks_for` is deliberately lenient — an unparseable `.marks.json`
reads as "no marks" so a review page still loads. The write path inherited that
leniency through the same reader, so one flag click appended a single entry to an
empty list and atomically replaced the file: every mark in the booth gone,
silently, from a click. Reproduced first, then fixed.

The fix is an asymmetry, not a retreat from leniency. Reads stay lenient; writes
go strict through `_read_raw_strict`, which distinguishes bytes-present-but-
unreadable from absent and valid-but-empty, and raises `MarksCorrupt`. The
damaged bytes are left on disk. Routes answer 409 rather than 500 — the service
is fine and the request was well-formed, the state on disk is not — and the body
says what to do, because the alternative the operator reaches for otherwise is
deleting the file, which is the thing being protected. The CLI says it in one
line instead of a traceback.

A PICK COULD NOT TARGET AN ITEM. `Mark.target` carried one, `marks_for_target`
retrieved by it, and the panel already rendered "on <item>" — but `declare_pick`
had no parameter for it, so no session could produce one. A question about one
artifact is the whole point of the 2026-09-09 inline-placement ruling; the door
was simply missing.

THE IMPORTER STRANDED AN ANSWER. A stem already present as a mark was skipped
wholesale. If a session had re-declared that stem through marks while the
operator's choice sat in the legacy sidecar, that choice was lost permanently —
reads are forbidden from looking at sidecars. The declaration is still skipped
(idempotence holds) but a legacy answer is now adopted when the existing mark is
an unanswered pick, and an answer made through marks is never overwritten.

INV-3 NAMED A SURFACE NOTHING TESTED. All four arms converged on it: the rule
protects gallery tile, zoom view and doc view; the falsifiable check covered one.
The doc view was implemented and untested, so shipping it unmarked would have
passed. Three tests now, one per surface.

The contract carries the full triage, including two findings accepted and NOT
closed: INV-2's and INV-5's checks comply in letter — openness can be re-derived
without spelling the grepped pattern, and importlib inside a function defeats the
AST walk. Both describe a future careless change, and the honest statement is
that these checks raise the cost of drifting rather than making it impossible.
Recorded rather than papered over.

Also pins the three prose ambiguities the panel found, normatively and once each:
what counts as open, the three distinct broken-declaration cases, and INV-6,
which had named a helper that does not exist and forbidden the calls that helper
must make.

253 tests.

vh c7f9437a64 feat(marks): one primitive for operator judgment, so the loop stops running through chat
Five mechanisms existed to get one question next to one artifact. Three of
them were the same thing wearing different clothes, and the third of the three
had no code at all: the operator picked winners out of a 270-image set and
told the session in conversation. `sindra-finalists` is 86 items, every one
captioned, with the selection encoded in the booth's NAME.

A MARK is operator judgment attached to a target — the booth, or one item in
it, addressed by the `rel` U1 established as item identity. Three shapes:

  pick — one of N options a session declared in advance   (was: an ask)
  note — free text the operator volunteered               (had nothing)
  flag — this one                                         (had nothing)

One file per booth, one read path, one place openness is computed, one slot
beside the artifact. The storage shape is the operator's call (2026-09-21) and
follows from U4: "does this booth still owe an answer?" gets asked per booth
per sweep tick and per card per index render, so it has to be one read and not
a walk of a booth holding 270 files. Marks are also not links.md — that is an
O_APPEND content-hash log because 17 handles write it concurrently, whereas a
booth's marks see one session and one operator, so locking the common path
costs nothing.

The 2026-09-09 pick semantics are preserved by NOT rewriting them: partial
answers legal, a blank question lands in `unanswered`, `complete` false until
every question has a pick, the only refusal a submission carrying nothing.
`write_answer` split into the pure `build_answer` plus the storage that went
away with the sidecar; `normalize_ask` untouched.

Three findings worth naming, because each was caught by a gate rather than by
reading the diff again:

  * The seam review found `inline.place` indexes asks by SUBSCRIPT — the only
    consumer in the service that does — so a frozen dataclass breaks it, and
    `inline.py` had been missing from the contract's scope entirely.
  * A retargeted test found a regression in the legacy importer: a malformed
    sidecar that renders "broken" today would have silently vanished on
    migration. It now imports carrying its reason.
  * A partially-answered pick counted as CLOSED on the index while the panel
    beside it rendered it "partial" — the two disagreed about one booth. Open
    is the reading U4 needs, and it is declared rather than smuggled in.

`GET /b/<n>/marks.json` is new and load-bearing: sessions on other hosts polled
`<stem>.answer.json` over HTTP, so removing the sidecar without it would have
taken that capability away. `/b/<n>/asks` 308s to `/marks`. Legacy sidecars are
imported, never deleted — four are live and unanswered.

Also records the operator's deterministic-order directive as a cross-cutting v1
invariant, in ROADMAP.md with the per-collection rule table and as CLAUDE.md
invariant 6. The Booth's job is comparison; an order that moves between renders
does not crash, it misfiles the judgment.

242 tests. No version bump — a release tier for this is the operator's call.
2026-09-21 23:38:27 -07:00
vh 5f2c9a6a60 fix(booth): release was painting over the delete ×, which was unclickable
Operator: "release button covers delete button". Measured before touching
anything: release 58x24 at (323,266), × 30x30 at (349,268) — 30x22 px of
overlap on a 30px button, and `elementFromPoint` at the ×'s centre returned the
release form. The × I added yesterday was 100% unclickable from the moment it
shipped.

Cause: both were `position:absolute` on the same corner, each with its own
guessed offset, and `release` is the later sibling so it won. Replaced with one
flex row positioned once — release left, × right at the card corner where the
ephemeral lane's × already lives, so muscle memory transfers and neither can
drift back on top of the other when a label changes width.

Verified by measurement, not inspection: overlap 0 px, and clicks at each
control's centre now land on that control. The ephemeral lane's × and ★ were
re-checked and are unaffected.

ADDS scripts/layout-probe.py, because markup inspection STRUCTURALLY cannot see
this and I have now shipped two dead controls in two days by reading templates
instead of rendering them. It asks a real browser what a click at each
control's centre would hit.

It took four iterations to become trustworthy and the failures are the point:

  1. `top.contains(el)` counted an ANCESTOR overlay as a hit -- the exact case
     it exists to catch. Version one reported OK for a real overlay.
  2. elementFromPoint is viewport-relative, so everything below the fold read
     as occluded and buried the real findings.
  3. getBoundingClientRect() on a WRAPPED INLINE element is the union of its
     line boxes, whose centre lands in the gutter between them -- three zip
     links reported occluded by their own parent. Real geometry, wrong question.

Only the fourth version fires on a genuine overlay while staying silent on the
clean page. Both controls were run; a probe never seen to fail proves nothing.

173 tests pass.

vh b569a5bb50 feat(booth): close the keep round trip, and add cosmetic per-item blur
Two operator requests.

KEEP, BOTH DIRECTIONS. The kept lane could already release a booth back to
ephemeral, but an ephemeral booth could only be promoted from a shell -- so the
round trip was closed only if you had ssh. The /keep route and the `booth keep`
verb both already existed; only the button was missing. Adds ★ to the ephemeral
card, mirroring × on the other shoulder.

BLUR. Per-item cosmetic censoring: `booth blur <name> <file>...`, a ◌/◉ toggle
in each caption row, and 👁 click-to-reveal. State is `.blurred` in the booth
dir, one booth-relative path per line -- the same filesystem-is-the-state idiom
as .pins and .forever. An empty set deletes the marker rather than leaving a
zero-byte file, so `ls -a` tells the truth.

⚠ BLUR IS NOT ACCESS CONTROL, and the code, the docs and a test all say so on
purpose. A blurred item is still served at its own URL, still in the zip, still
on disk. The Booth has no auth by design. test_blur_is_cosmetic_the_file_is_
still_served asserts the 200 deliberately: if someone later "hardens" this into
a 403 that test fails, and it should, because half-implemented access control is
more dangerous than none.

Reveal is per-viewer and never persisted; a reload re-hides. With JS off an item
stays blurred, which is the safe direction to fail in.

Two things the first pass got wrong, both caught by checking rather than
assuming:

  * The cover thumb. index.html has IDENTICAL markup in the kept and ephemeral
    lanes, so a single-occurrence replace patched only the kept one and the
    ephemeral front page happily displayed the thing someone had hidden. The
    test that caught it was itself wrong first -- it matched the bare string
    "blurred-thumb", which is in base.html's stylesheet on every page and so
    passed in both states. It now asserts the attribute.
  * Inline docs render through their own <figure> branch and were left
    unblurred -- the branch that puts readable text straight on the page, so it
    needed blur more than images do. The suite passed; a live curl caught it.

165 tests pass (154 pre-existing, unchanged).

vh 22ec06fcaa feat(booth): per-row link removal + render the link board as real UI
The standing link board is the one MULTI-WRITER booth -- every agent session
appends operator-facing URLs to it. "Delete the folder" was the only
granularity available, so removing one dead link meant hand-editing markdown.
It is 32 rows and only grows.

  booth links                 row number, entry id, raw row
  booth unlink 3              by row number
  booth unlink 8b40e0a5       by entry id (what the UI's x posts)
  POST /b/<name>/unlink       form field `entry` = content id

ROWS ARE ADDRESSED BY CONTENT ID, NEVER BY POSITION. The board is append-only
and multi-writer: another session can post between listing it and clicking x,
and an index would then delete a neighbour. An id either matches the row you
saw or matches nothing. A row number typed at the CLI is resolved to its id
BEFORE anything is deleted. Appends and prunes now take the same flock on
.links.lock, so a post cannot be lost inside a prune's read-modify-write.

UI: a booth carrying links.md renders as rows -- description, URL, provenance,
copy button, per-row x -- instead of a markdown blob. links.md is filtered out
of the gallery so it does not appear twice; the header counts LINKS not files;
the empty-state and the one-click "Wipe now" both stand down for a board (same
rule as the kept lane: nothing durable is one click from gone).

booth/links.py extracted, STDLIB ONLY. The CLI needs this logic and must not
require the service venv -- importing app.py drags in FastAPI, so deleting a
line from a text file would have needed a web framework installed.

THREE BUGS FOUND BY TESTING, all in the shell wrapper while the module was
correct throughout -- module-only tests would have caught none of them:

- `[ "$n" -eq 0 ] && echo ...` as the LAST statement made `booth links` exit 1
  whenever the board had rows. `unlink`'s index lookup calls it inside $( )
  under `set -e`, so a successful listing killed the caller and the removal
  silently did nothing while reporting success.
- ids are 8 hex chars and roughly one in forty is ALL DIGITS; those were read
  as row numbers, resolved to nothing, and removed nothing. Now disambiguated
  by the id's actual shape, not by "is it numeric".
- filtering links.md out of the gallery left `items` empty, so a full board
  rendered "This booth is empty" and an empty <div class="gallery"> under 32
  visible rows.

87 tests (was 76): parser tolerance of hand-written prose, content-id
stability across concurrent appends, removal precision, UI branch behaviour
for board/normal/empty booths, and subprocess CLI tests pinning the two shell
bugs. Deployed to nh3-dev and verified against the live 32-row board
read-only; board file byte-identical afterwards.
2026-08-23 12:55:33 -07:00
vh d88f235688 feat(booth): kept boards can be deleted from the UI; document the TTL-reset trap
Kept boards had no delete path in the UI at all. The kept lane deliberately
omits the wipe control -- a one-click wipe next to the durable stuff is a
footgun -- but "deliberate" had been implemented as "impossible": the only
routes out were ssh or a hand-written API call.

Now it is two deliberate acts. A `release` control on kept cards drops the
sentinel, the board moves to the ephemeral lane, and the existing x wipes it
from there. Release is reversible -- POST /b/<name>/keep pins it again.

  POST /b/<name>/unkeep   release the pin
  POST /b/<name>/keep     pin it (round-trip, so release is not a one-way door)

FOUND WHILE TESTING, and it invalidates the previously-documented workaround:
removing the sentinel BUMPS the booth directory's mtime, and booth age is the
newest mtime in the tree -- so a released board's clock RESETS from 10,000s to
0s and it survives another full TTL. The old comment said "remove the sentinel
first (it rejoins the sweep)", which is true but means the board lives another
24h, not that it gets reaped. Unkeep-and-wait is a delay, not a delete.

test_releasing_a_board_RESETS_its_ttl_clock pins that behaviour deliberately so
nobody re-derives the workaround. Release is what unlocks the x; the x is what
deletes.

CLI: `booth rm` already worked on kept boards but said nothing about it. It now
announces "(was KEPT -- durable board)" so wiping something durable can never
look identical to wiping run output. Not a block -- a CLI user naming a booth
is being explicit.

5 new tests (67 pass). Verified live on nh3-dev: release renders on all four
kept boards, the ephemeral lane keeps its x, and the links board is untouched
with its sentinel intact.
2026-08-23 10:42:32 -07:00
vh 95228299bc feat(booth): kept boards — a .forever sentinel and a standing link board
Agent sessions hand the operator URLs and they drown in terminal
scrollback. The Booth is the right home for them — it already has the one
property that decides adoption, which is that a session can publish with
mkdir and cp, no API key, no schema, no deploy — but everything in it dies
in 24h.

So: a booth containing `.forever` is never swept, and renders in its own
Kept lane at the top of the index. Opt-in per booth, so the ephemeral
default is untouched and nobody inherits a cleanup chore. `rm` the
sentinel and the board rejoins the sweep; the CLI verbs are sugar over
exactly that, which keeps the filesystem-is-the-state model honest.

The pin is deliberately NOT wired into is_expired(). That stays a pure age
question feeding the `expires_in` countdown; only sweep_once() honours the
sentinel. Keeping expiry arithmetic and reaper policy apart means they
cannot drift into each other.

Kept cards are visually separated per Australis: a 2px top edge in aurora
blue, the one accent border the system sanctions. They show "kept" instead
of a countdown, and they deliberately lose the one-click wipe button — a ×
next to the durable stuff is a footgun, so removing a kept board is a
two-step act.

`booth link <url> [description]` appends to the standing `links` board,
creating and keeping it on first use. Entries carry provenance (handle or
hostname, plus a timestamp) because a bare URL is unreadable three days
later. The append is one printf of one line to an O_APPEND fd — atomic
under PIPE_BUF on POSIX — which matters because many agents post to one
board and interleaved half-lines would be the obvious failure mode.

Seven tests cover the sentinel: detection, survival of a sweep that wipes
its neighbour, the deliberate is_expired/sweep_once split, the listing
flag, the sentinel not inflating item counts, and both lane-rendering
directions. Two of them originally asserted on the bare strings "Kept" and
"kept-grid", which passed for the wrong reason — those also appear in the
inlined stylesheet served on every page — so they now assert the full
class attribute. 55 pass.

Also corrects the Homepage card's description, which advertised a flat 24h
TTL that is no longer the whole story.

vh 55c0655126 feat(booth): add The Booth — ephemeral media drop board for CC sessions
A standing user-level web server (nh3-dev :8090) that renders drop-folders
under ~/booth-data as ephemeral media "booths" so Claude Code sessions can
surface A/B renders and smoke results to the operator, then let them self-wipe.

- Scan-and-serve model, no database, no upload API — a booth is just a folder.
  A folder's own index.html is served verbatim; otherwise an auto-gallery of
  images / webm+mp4 video / audio is rendered, with <file>.txt caption sidecars
  folded in (labels A/B pairs).
- 24h TTL from newest mtime in the tree; background sweeper wipes stale booths.
- Path-traversal + symlink-escape guarded; delete via UI button or DELETE API.
- FastAPI + Jinja2, runs from the checkout under systemctl --user (booth.service),
  alongside the other nh3-dev fleet sidecars. 15 tests, all green.
- Homepage tile added (Apps -> The Booth, siteMonitor /healthz).
- Harden the homepage rsync doc: exclude *.bak* and logs/ so --delete can't
  wipe the host's dated services.yaml backups (footgun found deploying this).
