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.

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.

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.
 2026-09-22 14:34:28 -07:00
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.

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.

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.

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.

A declaring page was therefore NOT served as its author wrote it, which is
this unit's headline promise, and the test could not see it because its
fixture was LF-only ASCII. Found by a cross-frontier bug-hunt panel.

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.

"""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.

ONE PREDICATE, THREE CALLERS — the CLI's `link` refusal, the board's

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
cannot disagree about what is reachable.
NEVER RAISES. A board row is arbitrary operator-editable text; a predicate
that raises on one row takes the whole page.

The page is served untouched and carries its own CSS, so nothing here may

inherit from base.html. Since U3 these fragments do not reach the page by
string substitution: they are rendered here, handed over
`/b/<name>/embed.json`, and MOUNTED INTO THE DOM by `/_booth/embed.js`. The
scoped `.bk-ask-*` styles live in that file alongside the code that needs
them, which is why this template no longer emits a `styles()` block.
These macros stay the ONE renderer of an ask fragment. embed.js places what
comes back and never builds one.
Per-question fragments are wired to ONE form with the HTML5 `form=`
attribute, so a four-voice report can put each radio group under its own
audio block and still submit all four picks in a single POST — which is what

# 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: "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.)"
language: "python + javascript"
complexity: "medium"
estimated_loc: 420
confidence: 0.82
used_by:
- "booth.app.booth_view (the verbatim branch: one read, one substring check, one conditional append -- replacing inject_asks + wrap_verbatim_html entirely)"
- "the operator's verbatim reports (4 of 21 live booths ship their own index.html; 2 of those 4 use the placement DSL, so the migration is not hypothetical)"
- "report authors (the declared line is the new public API for a booth that wants Booth chrome where it chooses)"
touches:
- "booth/static/embed.js (NEW -- the mount script and the chrome CSS, one asset. Read ONCE at app startup, never per request; see INV-5.)"
- "booth/app.py (DELETE wrap_verbatim_html, _insert_before, _insert_after, _ICON_RE, _HEAD_CLOSE_RE, _HTML_OPEN_RE, _DOCTYPE_RE, _BODY_CLOSE_RE, _HTML_CLOSE_RE, _BACK_CHIP, asks_chip, inject_asks, FAVICON_LINK and the `from booth.inline import` block. ADD EMBED_SRC/EMBED_SCRIPT_TAG, the startup read of embed.js, GET /_booth/embed.js, GET /b/{name}/embed.json, and the rewritten verbatim branch of booth_view.)"
- "booth/inline.py (DELETED ENTIRELY -- 119 lines. Nothing else imports it; `scripts/booth` never did, so the stdlib-only CLI surface is untouched. ONE line survives the module: `form_id`, which builds the shared form element id the fragments bind to, moves into booth/app.py beside the route that renders them. It is not placement machinery and dying with the placement engine would take the fragments with it. Seam review, SR-3.)"
- "booth/templates/_ask_inline.html (DELETE the `styles()` macro and rewrite the header comment: the fragments are now mounted by embed.js, not substituted by regex, and `No JavaScript` stops being true.)"
- "tests/test_booth.py (DELETE the five test_wrap_* tests and test_verbatim_booth_wrapped_with_back_chip -- they test a mechanism this unit removes; the FAVICON_LINK import goes with them)"
- "tests/test_asks.py (the inline-placement block, ~L480-590: assertions that server-rendered fragments appear in the page body become assertions about the embed payload. The BEHAVIOUR they encode -- every question reachable, a scattered form still submittable, a typo'd id left alone -- is preserved and re-asserted, half in Python and half in the browser.)"
- "tests/test_embed.py (NEW -- the payload, the injection rule, the no-hot-reload guard)"
- "tests/test_embed_browser.py (NEW -- Playwright against a real Chromium: the placement algorithm and the form association, neither of which the Python suite can see. SKIPS, never fails, when playwright or the shared browser is unavailable.)"
- "pyproject.toml (test extra gains `playwright>=1.60,<1.63` -- the range is the set of releases whose pinned Chromium revision is present in the box-wide /opt/ms-playwright store. Stated explicitly because it is invisible otherwise: 1.63 wants chromium-1243, which is NOT there, and the failure is an opaque `Executable doesn't exist`.)"
- "docs/design/information-architecture.md (the `What this deletes` list becomes what this DID delete; the standalone /asks bullet is corrected -- U2 already reduced it to a 308)"
- "ROADMAP.md (U3 row struck through; the ordering table gains the two orders this unit states)"
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,

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/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.
- Liveness is *flagged*, not enforced. A bench that stops answering gets a

`_HTML_CLOSE_RE`, `_ICON_RE`) and the doctype/charset-ordering constraints

there. The standalone page it named is gone, but the URL is in the operator's
history and in landed reports, and a dead link teaches nothing.

# PENDING — fleet note to the 17 consuming handles
**Status: DRAFTED, NOT SENT.** Blocked by the auto-mode classifier on
2026-09-22 because it is a multi-recipient send, which CLAUDE.md gates on
explicit operator approval. The operator's blanket "accept all recs" was
read as ratifying the note's CONTENT, not as the specific broadcast
approval that rule requires — and the classifier agreed. Not worked around.
**To send it:** the operator says go, or adds a Bash permission rule for
`postbox send`. Recipients (17, from the live board's provenance):
hamr-dev tts-dev nh3-dev shutter-dev infra-ops comfy-dev ldp-dev
design-dev pewpew-dev peedlar-dev brokkr-smithy-dev draupnir
bifrost-dev yt-voice-clipper-dev svos-dev jackdaw-dev brokkr-scan-dev
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 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.
⚠ Reproduce with the fixture in
`tests/test_embed.py::test_a_wrongly_shaped_answer_costs_its_pick_not_the_report`,
whose closing comment points back here.

## 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 |

| 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
else. Related: [[2026-09-22-the-browser-became-a-test-surface]],

# 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]].

_As of 2026-09-22:_
- **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.
- **U6 SHIPPED (`v0.6.0`) with a late fix (`v0.6.1`). PUSHED.** `main` and both
tags are on `origin` as of 2026-09-22 — the tree is no longer single-copy.
→ `persistent-memory.d/2026-09-22-u6-benches-released.md`
- **THE OPERATOR RULED ON EVERYTHING OUTSTANDING (2026-09-22, "accept all
recs").** Four of five settled and executed; one blocked by the permission
layer. Nothing is waiting on him. →
`persistent-memory.d/2026-09-22-operator-ruled-on-the-open-five.md`
- ✅ **U7 IS LANDED — ALL SEVEN v1 UNITS ARE IN.** The fourth component
(filename-prefix groups) is built; `test_no_group_rail_is_shipped_yet` was
deleted in the same commit, as required.
→ `persistent-memory.d/2026-09-22-u7-landed-and-a-table-that-did-not-reproduce.md`
- 🔶 **THE 1.0 CUT IS NOW A DECISION, NOT A DEPENDENCY, AND IT IS HIS.** The v1
target is met. A major bump needs explicit operator approval; nothing in the
code is waiting on it. The open fork: cut `1.0`, or stage a `0.7.0` first.
**Not bumped — the work is committed as commits, which are not releases.**
- ⚠ **U7'S CONTRACT CARRIED A MEASUREMENT THAT DID NOT REPRODUCE**, and it was
the number the scope departure rested on. The stated rule gives 24 and 27
groups where the table claimed 5 and 1; the table was assembled from two
different heuristics. **A cold contract-review panel cannot catch this** — the
artifact is internally plausible. Re-run any measurement a contract's scope
rests on before implementing it. Same detail file.
- ⚠ **A MUTATION HARNESS NEEDS A GREEN BASELINE AND CACHE DEFEAT**, or it
certifies falsifiers without running them. Both defects bit in one session.
→ `persistent-memory.d/2026-09-22-a-mutation-harness-that-certified-a-broken-test.md`
- **639 tests green; 12/12 new falsifiers mutation-proved. Deployed; 21/21
booths 200.** ⚠ The set churned again mid-session (19 → 21).
- 🔶 **A bug-hunt panel is IN FLIGHT** — heid thread `01M368G2Y0JMTJ2T7M3JMTXV5Z`,
dispatched 2026-09-22 21:31 PDT over the U7-groups diff. If its reply has not
been consumed, drain `/althing:inbox` and triage before treating U7 as closed.
- 🛑 **STANDING RULING — NO ANNOUNCEMENTS OUT OF THIS REPO, AND THE OPERATOR
SENDS THE EVENTUAL ONE HIMSELF** (operator, 2026-09-22). Verbatim: *"no
announcements until the entire arc is done, and even then i'll do it myself."*
Two clauses, both binding: **(a)** no althing announcement of any kind ships
from booth-dev until the v1 arc is COMPLETE — not per-unit, not at the 1.0
tag, not "just the peers who consume it"; **(b)** when the arc IS done, the
announcement is HIS to send, not a thing to ask permission for. This is
STRICTER than `~/.claude/CLAUDE.md`'s broadcast gate, which merely requires
approval — here the send is not the agent's to make at all, so *asking* is
also out of scope. Do not offer, draft-and-await, or surface it as a pending
decision; it is settled and not a standing question.
**The 17-handle `booth link` note is consequently REASSIGNED, not blocked.**
The full draft + recipient list stays at
`docs/pending/fleet-note-booth-link-refusal.md` as MATERIAL FOR HIM. It is no
longer an open loop, no longer awaiting approval, and no longer a thing to
raise. Same for anything U4's `keep`-semantics change would have warranted
telling peers.
- ⚠ **NOT SEEDED, and this survives the blanket ruling.** "No seeding yet" was a
SPECIFIC prior instruction, not a recommendation of mine, so "accept all recs"
does not override it. `.benches.json` does not exist in `~/booth-data`.
- **A U7 directive (D-0011) misrouted to infra-ops and is SUPERSEDED.** Miranda
confirmed directly. Nothing to act on.
→ `persistent-memory.d/2026-09-22-a-directive-misrouted-by-pane-title.md`
- ⚠ **THE 17 CONSUMING HANDLES WERE NEVER TOLD that `keep` stopped meaning
"waiting on an answer"** — and the note above does not tell them either; it is
about `booth link`. **This CHANGES HOW THE 2026-10-06 RE-COUNT READS**: a flat
`.forever` rate does NOT falsify the diagnosis.
- **Two dated predictions pending, not to be run early.** U5's adoption
re-measure **2026-09-29**; the `.forever` re-count **on or after 2026-10-06**.
- **FIVE `/heid*` methodology proposals sit with the operator**, untracked by
his choice.
- The booth set churns hard: 26 → 24 → 25 → 23 → **19**. Re-count rather than
trusting any number here.

reaches the very object the closure captured. What it pins is the guard

"""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.
