timothyandClaude Opus 5 a973fc48e2 fix(651): review round 6 — fail closed on a missing ETag; validate elements, not containers
HIGH: "the draft is only created alongside the ETag" was not the invariant I claimed. The
response can OMIT the header, in which case the draft was still created and the subsequent
PUT carried no `If-Match` — the round-4 force-write hole in a new form. The editor now fails
closed: no concurrency token, no editable draft (error + Retry/Back). Six tests were leaning
on ETag-less detail mocks, which is exactly how this stayed invisible; every single-record
GET mock now goes through a `detailResponse` helper that always sets one, and the absent
case is tested explicitly — asserting zero PUTs are even reachable.

MEDIUM: the detail GET had neither deadline nor recovery affordance, so a never-settling
request left a bare spinner with no way out. It is now raced against a 15s deadline, the
loading view carries a Back control, and the error view offers Retry.

MEDIUM: the malformed-body guard checked the container, not the elements. `[null]` passes
`Array.isArray`, reaches `setResults`, and throws on `option.id` during render; a wrong-typed
`id` would commit an invalid value through `onSelect`. Each element is now validated, and a
malformed payload is treated as a failed attempt so it stays retryable rather than cached.

MEDIUM: the decision record's `rule:` — the authoritative string, copied verbatim into the
catalog that is the documented entry point — still mandated the machinery round 5 deleted:
touched-field hydration, `replaceDraft`, conflict reconciliation. Anyone following it would
have rebuilt the rejected design. Rewritten to the initialize-once policy and the catalog
regenerated; historical prose no longer says `replaceDraft` "is now" separate.

MEDIUM: the replacement Reload test resolved its second GET immediately and returned a
non-null selection, so it observed neither a pending reload nor the dirty-selection discard —
removing `setDraft(null)` could leave it green. It now holds the reload open, asserts the
form is ABSENT while pending, and returns `selectedId: null` to pin the case round 3 showed
could resurrect a dirty id over a collaborator's change.

Checklist item taken from this: when a mechanism is deleted, the decision record's `rule:` is
the single most likely thing left stale, and the one string that propagates.

timothyandClaude Opus 5 78cd9e0ebf fix(651): review round 5 — delete the draft-reconciliation layer instead of extending it
Took the coordinator's proposal. Rounds 2-4 built and rebuilt a layer that merged a late
detail response into a draft the user was already editing; it produced a HIGH finding in
three consecutive rounds, three of them cross-user lost updates. Round 5's finding was
unfixable in kind: `identityConflicts` had no immutable baseline, so it could not tell "the
user changed this" from "the server changed this" — giving both a missed conflict (same
type, different id: v2 ETag installed over the user's id, third lost update) and a false one
(local type switch: dialog opens spuriously, and "Keep editing" leaves `etagRef` null so the
next PUT is a silent FORCE-WRITE).

The race is removed rather than refereed. `RerunCollectionEditor` now initializes its draft
EXACTLY ONCE from the detail GET and withholds the form until it lands; conflicts are
detected at save time by the `If-Match` -> 412 -> Reload path that already existed. Deleted:
`touchedRef`, `hydrateDraft`, `hydrateSelection`, `hydrateIdentity`, `identityOf`,
`identityConflicts`, `replaceDraft`, `replacePending` and the hydrate/replace load mode.
Reload simply sets the draft back to null and re-runs the same load, so the form is
unmounted while the replacement is in flight — round 4's MEDIUM-4 becomes structural.

Two facts make this lossless rather than a regression. The list row could never have helped:
`GetPagedRerunCollectionsHandler` applies ZERO `.Include()`s where
`GetRerunCollectionByIdHandler` applies fourteen, and both project through the same mapper,
so the list response is a strict SUBSET of the detail one — the id round 1 preserved from it
is null in production for every row (#671), and existed only in test fixtures. And
FillerPresetsScreen/PlaylistsScreen already worked this way; RerunCollections was the
outlier, which is why nearly every finding in rounds 3-5 traced to it.

The ETag is now written in the same callback that sets the draft, so `draft != null` implies
an ETag and a PUT without `If-Match` is unreachable by construction.

MEDIUM-2: a failed search retried every debounce forever — a fresh `{ok:false}` re-ran the
effect and the success guard declined it. `ok` (is the held answer authoritative) is now
separate from `attemptRef` (have we already tried this exact source+query); only an explicit
reopen/focus/edit re-arms a retry.

MEDIUM-3: a malformed 2xx body resolves as `undefined` (client.ts swallows the SyntaxError),
and `setResults(undefined)` threw on the next render. A non-array is now treated as a failed
attempt, and `search` is raced against a 10s deadline since a caller-supplied promise carries
no abort signal.

Two tests were hiding findings and are fixed: the failed-search test pressed Escape before
the unintended retry could fire, and the round-4 conflict test claimed to select id 9 while
firing the already-selected id 5. Fourteen tests of the deleted machinery are gone with it,
replaced by six asserting the new invariants.

timothyandClaude Opus 5 f601d957a6 fix(651): review round 4 — an id never travels without its namespace
Round 4's through-line: rounds 2-3 made HYDRATION treat {collectionType, selectedId,
selectedName} as one value, but the fix was applied to the structure that was named rather
than to every structure that carries an id. Three more instances of the same class, plus
two independent findings.

HIGH-1 + HIGH-2 (one change, per the structural directive): every result, option and
cached result set now carries its SOURCE, and identity is compared as (type, id).
- `SearchPicker` takes a REQUIRED `source` prop and caches results against (source, query),
  not query text. Keying on text let the round-3 re-query guard SUPPRESS the new source's
  request and leave the previous namespace's hit clickable under the new label — a
  Collection id stored as a SmartCollection id. Results from another source are now hidden
  outright rather than dimmed: they are not stale, they are wrong. Required rather than
  defaulted, because a default would silently opt every caller out.
- `pickerFor` tags list-backed options with the type they were loaded for, on both
  RerunCollectionsScreen and PlaylistsScreen, so the previous type's rows stop being
  selectable the instant the active type changes rather than lingering through the
  replacement load.

HIGH-3: a touched identity contradicting the server's type is a CONFLICT. Pinning the
user's edit was right; adopting the response's newest ETag alongside it authorized a Save
that silently overwrote the collaborator's type change with no 412. The conflict dialog is
raised and the stale ETag kept, so even a forced Save 412s. With round 3's Reload defect
this is the second cross-user lost update, so it is recorded as a category: never install a
save-authorizing ETag over a local edit the server contradicts.

MEDIUM-4: the editor is inert while a Reload is pending. The dialog closes immediately, so
an edit typed before the replacement landed was silently erased along with the touched set
that protected it.

MEDIUM-5: cached search provenance records `ok`, so a transient 500 is retried instead of
being cached as an authoritative "No matches" that reopening can never clear.

Also: `npx tsc --noEmit` typechecks NOTHING in web/ — the root tsconfig is solution-style
("files": [] + references), so it resolves to zero inputs and exits 0. The real gate, and
what CI runs, is `npm run typecheck` (tsc -b). Verified by planting a deliberate type error:
--noEmit stayed green, -b caught it. Running the real gate surfaced four genuine errors in
tests written earlier this branch (a missing required prop and three `never has no call
signatures` from closure-assigned mock variables), fixed with the repo's existing
holder-object pattern rather than casts. Recorded in spa-conventions so the next session
doesn't repeat it.

timothyandClaude Opus 5 5b0ba08aab fix(651): review round 3 — cover the class, not the named instance
Round 3 found four defects that are all one mistake: each earlier fix enumerated one
instance of a class instead of covering the class. Fixed by asking what else is in each
class rather than patching the named case.

CRITICAL — cross-user lost update. Conflict "Reload" ran through the refresh policy with a
touched-set reset. Because a reloaded RemoteStream reports `selectedId: null` under the
#671 server gap, the keep-ours-when-the-id-is-missing fallback restored the user's DIRTY
selection, the fresh ETag was installed, and the next Save silently overwrote the
collaborator's change — with the very edits the user had explicitly asked to discard.
"Keep ours when the server omits the id" is a REFRESH policy; a reload is a REPLACE.
`replaceDraft` is now a separate function and the mode travels with the load, so the two
cannot be confused at the call site.

HIGH — `collectionType` and the selection still hydrated apart. `collectionType` says which
table an id indexes, so it is part of the same indivisible value as the id and its name;
splitting it is the identical bug to splitting id from name. A record retyped server-side
mid-load hydrated the new type while retaining the old id, displaying and saving a
Collection id as a RemoteStream id. All three fields now resolve as one `Identity` unit:
either half touched pins the whole thing, a differing type takes the response's unit whole
(null selection included), and only once both sides agree on the type does the id/name rule
apply.

HIGH — stale results were still committable by pointer. Enter was gated and `onClick` was
not: the same defect in another modality. The guard moved into the single `choose()` sink
so every commit path is covered, including any added later, and a superseded list is now
genuinely inert (`aria-disabled` + dimmed) rather than looking normal and silently
no-opping.

MEDIUM — reopening after Escape re-queried an already-current result set; the duplicate
response reset the cursor the user had since moved, leaving Enter doing nothing. The effect
now skips the search when the cached results match the trimmed query, and reopening places
the cursor per the ARIA APG instead of swallowing the keypress.

Also corrects an overstated justification in FillerPresetsScreen: the render-time id check
was dropped because there is no reachable path TODAY, not because "every writer sets both"
— the initial load writes the id alone, and a stale resolver can repopulate the label after
a clear. Same enumeration error as the findings above; the comment now says what is
actually true and what to do if a path appears.

Note: an apostrophe I introduced inside the single-quoted `rule:` scalar broke PyYAML while
`decisions_validate.py` (hand parser) stayed green — the same trap class as the unquoted
`#`, caught only by scripts/tests.

timothyandClaude Opus 5 ba52219a9a fix(651): review round 2 — hydrate untouched fields, never merge a selection field-by-field
Re-review of a04d9f0b came back BLOCKED: the F1 merge fixed a visible data loss and
introduced a silent one. Four blockers, all web-only.

BLOCKER 1: `selectedId` and `selectedName` were coalesced independently, but they are one
value. Against a Song response (id resolves, name does not), a user selecting a different
song while the detail GET was in flight got the NEW name paired with the STORED id — chip
read "New Song", Save wrote 42, no error and no visual cue. Strictly worse than the
original defect, which at least cleared the field visibly. The same merge resurrected a
deliberate clear and reverted a type switch.

Replaced with two rules. The id/name pair resolves atomically (no id in the response ->
keep ours whole; same id -> its name may fill ours in; different id -> take theirs whole).
And hydration loses every race against the user: a `touchedRef`, fed by a single `edit()`
funnel so "touched" cannot drift from "changed", limits the refresh to fields the user has
not edited; an explicit conflict-reload clears it, since discarding local edits is its
entire purpose. Three interleaving tests hold the detail response open, act as the user,
then release it.

BLOCKER 2: Enter could commit a result from the previous query — highlight Alpha for "Al",
retype "Be", press Enter before the debounce. The highlight now drops on input change
rather than when the next response happens to arrive, and every keyboard action is gated
on the results matching what is typed. The stale list stays visible (hiding it flickers on
each keystroke), it just stops being actionable.

BLOCKER 3: Escape closed the popup while focus stayed in the input, where `onFocus` can
never re-arm it — the picker was dead until the user blurred and refocused. Typing and
ArrowDown now both reopen it.

BLOCKER 4: the LCG boundary test recomputed the divisor instead of exercising `lcg`, so
all three tests passed with the old `/ 0xffffffff`. Since the recurrence is a bijection
mod 2^32, the seed whose first step lands on 0xffffffff is solvable exactly (653637408);
the tests now drive the real generator into that state.

Also: the rerun #id-degrade and re-save tests did not await the refresh, so they were
satisfiable from the initial draft; they now await it and re-read live textContent. The
Episode/MusicVideo cases are relabelled as error-path guards — a 500 never reaches the
hydrate. FillerPresets' render-time id comparison is dropped as unreachable (every writer
sets label and id together, and the one async writer refuses a mismatched id); an
unreachable guard is an untested one.

#671 is referenced from spa-conventions §3b as the server-side root cause the client guard
defends against.

timothyandClaude Opus 5 e7e425fa25 fix(651): review round 1 — never clear an unnamed id, complete the Lucene escaping, keyboard-operable picker
Cold cross-family review of 57aefcdf. Six findings, all web-only.

F1 (HIGH, data-loss shaped): RerunCollectionsController.ProjectToResponseModel derives
BOTH selectedId and selectedName from the same eager-loaded navigation, and
GetRerunCollectionByIdHandler loads media metadata only for Show/Season/Artist/Movie
while MediaCollections/Mapper maps RemoteStream through `_ => null`. So opening a
RemoteStream rerun collection returned HTTP 200 with a null selection and the edit-load
refresh CLEARED a stored id, leaving Save permanently disabled. The refresh now merges
instead of replacing, so no path can clear an id it merely failed to name; the label
degrades to `#id`. Covered per affected type — RemoteStream, Episode, MusicVideo, Song,
OtherVideo, Image — plus a re-save assertion. The read-model gaps themselves are
server-side and are NOT touched here.

F2: `&` and `|` were missing from the escaped set, so `Rock && Roll` compiled with the
boolean operator live. Pre-existing in Auto-Tune's original helper, but propagated to
three more pickers — and now fixed for Auto-Tune too, since the helper is shared. The
test that claimed to cover "every Lucene special" carried its own hand-copied sample and
could not see its own omissions; it is now driven per-character off an exported
LIBRARY_PICKER_LUCENE_SPECIALS.

F3: a slow edit-load name resolution could relabel a newer selection. The label is now
keyed to the id it was resolved for AND refuses to overwrite a label naming a different
id — keying the render alone stops the mislabelling but discards the correct new label.

F4: searchLibraryPickerOptions clamps pageSize instead of merely defaulting it. A bound a
caller can exceed is not a bound.

F6: replacing a native <select> with an input+listbox dropped keyboard operability. Full
ARIA combobox pattern added — role/aria-expanded/aria-controls/aria-autocomplete,
Arrow/Home/End over aria-activedescendant, Enter to commit, Escape to dismiss, options as
non-tab-stops, cursor reset on each new result set.

F7: both is-mounted tests were unsound. React 19 no longer warns on setState-after-unmount
and an unmounted tree renders nothing either way, so the DOM assertion could not fail; the
hook re-arm test used rerender rather than an effect cleanup. Now: a hook-module mock
proving SearchPicker actually reads the guard and sees false, and a StrictMode
double-invoke for the re-arm. Both verified by removing the mechanism and watching them
fail. Same for the LCG divisor, which now has a direct boundary test.

F5 (FillerPresets collection-family names) is filed as #670, not fixed here.

timothyandClaude Opus 5 fad6805b91 feat(651): media-library pickers resolve by search instead of a bounded window
The three `getLibraryBrowseItems` pickers (RerunCollectionsScreen, PlaylistsScreen,
FillerPresetsScreen) populated a native <select> from a 100-row window over media-library
tables that can hold tens of thousands of rows. #644 made that truncation visible; it did
not make the picker usable, and paging to completeness would have been worse than the bug
(~200 serial requests, each more expensive than the last).

They now resolve by SEARCH through the shared `SearchPicker` over a new
`searchLibraryPickerOptions` helper: zero requests on mount or on a type switch, at most ONE
bounded request (25 rows) per settled query, nothing below 2 characters. Typed text is
compiled via the now-shared `titleContainsQuery` (`title:*<escaped>*`) rather than forwarded
raw, since the index's default field does not match bare title words. The current selection
renders from the owning record — `selectedName` for rerun collections and playlist items, and
for filler presets (which store only an id) a single by-id detail read — so editing an
existing record can never lose or fail to name its selection.

Class A stays put: bounded-by-construction admin lists still page to completeness via
`loadAllPages`, and the collection-family filler-preset types keep their bounded single page
(their `query` is a SQL LIKE, which a compiled Lucene query would not match). No server-side
cap is raised; this is a web-only change.

Folded in from #578: the rule-builder facet typeahead arms on focus rather than on mount (an
N-rule tree fired N unrequested lookups), both typeaheads pair their `seqRef` guard with a
shared `useIsMountedRef`, and the roundtrip test's LCG divides by 2^32 so `pick()` can no
longer index one past the end.

Decision record `spa.list-completeness-vs-bounded-pickers` is archived as superseded by the
new `spa.library-pickers-resolve-by-search`; spa-conventions §3b rewritten to match.

timothy 3885fd6aea docs(649): narrow the enumeration's stated guarantees to what it actually proves
Two limitations the cold review surfaced are now written where the guarantees are
described, rather than living only in a review transcript. Both are pre-existing and
tracked separately (#663, #664); neither is fixed here.

- Head-sha binding detects ONE-WAY movement. An A->B->A force-push round trip restores
  the expected sha, so the binding holds while the pages came from two states. The record
  previously read as though the race were closed.
- A commit status is repo-GLOBAL, so a success earned on one PR is inherited by any other
  PR with the same head. Same property that makes the per-sha binding work, read from the
  other end.

timothy d51255a8ef fix(632): "could not check" is a third outcome, not a quiet synonym for "nothing to check"
Cold review's substantive finding. The first draft collapsed an unreadable status
response into the graceful-adoption path: `vdesc` came back empty, so `recorded_base` was
empty, so the comparison was skipped IN SILENCE — and a later, successful status read
could then auto-grant, emitting "merge gate: satisfied" for a comparison that never
happened. A transient Gitea hiccup is not evidence that the base is unchanged.

The unreadable status response and a PR with no resolvable `.base.ref` now both fall
through to a human `ask`, leaving exactly one benign silent case: a verdict that predates
#632 and could not have carried the field. The emptiness check is done in SHELL before jq
sees it, same jq-1.6 rule as the rest of this file.

Also from review: the graceful-adoption test asserted only that the decision lacked the
issue tag, so it would have passed for a base-specific ask or deny whose wording omitted
it — the failure mode most likely to appear when someone edits these messages. It now
asserts on the word "base".

Recorded rather than fixed, because fixing it would be worse: docs-only PRs exit before
this check, since that carve-out short-circuits the gate earlier. It does not auto-grant
— it passes through to an ordinary permission prompt — so the exposure is a missing
warning on a merge a human is already confirming, not a silent merge. The record now says
so instead of implying the deny is unconditional.

Mutation-verified: collapsing the unreadable case back into graceful adoption, skipping
the check on a missing live base, and dropping the mismatch deny each redden their own
test and nothing else.

timothy 00e623c066 fix(632): bind a review verdict to its BASE branch, not only to its head sha
#622 made `review-verdict/h10` a per-sha required status, so a new commit cannot
inherit an old verdict — the required context is simply absent on the new head.
Retargeting a PR's base reaches the same end from the opposite direction: the head sha
and the status both hold still while the merge-base, and therefore the effective diff
the verdict was formed against, changes underneath them. #622's record claimed the
invariant holds "by construction"; this was the documented exception, and an unrecorded
exception is how a guarantee degrades into a habit.

`post-review-verdict.sh` now records the base branch in the status description as a
trailing `(base: <ref>)`, and refuses to write a status at all if the base moved between
reading the PR and posting — the same TOCTOU window the head check already covers, which
the head check cannot see because retargeting does not move the head.
`pretooluse-merge-consent.sh` reads the field back and denies when it no longer matches
the PR's live `base.ref`.

Two choices are load-bearing, and each is pinned by a test rather than left to a comment:

- The comparator is `base.ref`, NOT `base.sha`. `base.sha` tracks the base branch's tip,
  which moves whenever anything merges to `main` — comparing it would invalidate every
  open verdict on every unrelated merge, converting a rare-event guard into a permanent
  merge deadlock. A base that merely advances is out of scope by design: rebasing onto
  it moves the head sha, which the per-sha binding already covers.
- The field goes in the status DESCRIPTION, not the verdict comment. The comment body is
  parsed by `scripts/check-review-verdict.sh`, whose grammar had three false-opens in its
  history (#629); nothing parses the description, so this adds a field without reopening
  that surface.

Scope is stated honestly rather than overclaimed: this is DETECTION on the hook path
only. A commit status carries no base of its own, so the server-side required check
cannot see a retarget, and a merge driven through the Gitea UI or API is unaffected. That
is the accepted exposure — base changes are rare, manual, and this is a two-account repo
— but it now fails loud in the one place that evaluates consent, instead of living only
in a doc.

Verdicts posted before this change carry no `(base: …)` and get NO opinion rather than a
deny; denying would block every in-flight PR the day it lands, and the window closes on
its own since verdicts are per-head and short-lived.

Verified by mutation, six mutants, each killed by its intended test: remove the hook's
deny; compare base.sha instead of base.ref; drop graceful adoption; stop recording the
base; drop the TOCTOU guard; accept a PR with no resolvable base. The positive controls
matter more than usual here — the test PR is deliberately non-docs (a docs-only PR
short-circuits the whole gate and would never reach the base check) and the rest of the
gate is unstubbed, so "the hook denied" alone proves nothing.

timothy 9114a7e8af fix(649): point the ENFORCED review-verdict gate at the shared PR-file enumeration
#658 landed the shared implementation, `scripts/pr-changed-files.sh`, and rewired the
ADVISORY hook onto it. The ENFORCED copy — the one that writes the branch-protection-
required `review-verdict/h10` status — was left byte-identical to main, so its
fail-closed behaviour on a malformed or empty response stayed INCIDENTAL: an empty `n`
erroring `[ "$n" -lt 50 ]` to false. That is #649's second Done-when box, and the whole
point of the issue was that the gate with real authority was weaker than the gate with
none.

`review-verdict.yml` now:

- checks out the PR's BASE ref (`base.sha`, `persist-credentials: false`), never the
  head, so a PR cannot supply the code that judges it;
- runs `scripts/jq-preflight.sh` in FLOOR-ONLY mode — `--expect` here would deadlock
  every merge on `main` the day the runner's jq changes;
- calls `scripts/pr-changed-files.sh` and reads its EXIT STATUS, never its stdout on a
  failure path. The env trap flagged in review is handled: the script reads
  GITEA_BASE_URL and takes owner/repo as two separate arguments, so passing BASE_URL and
  a combined `owner/repo` would have silently fallen back to the hardcoded LAN default.

The ~40 lines of inline enumeration are deleted, so the two copies can no longer drift.
A base ref predating #658 has no such script; that posts `pending` with the reason
rather than dying with no status at all.

The drift guard is re-tightened from "the hook uses the shared script" to "BOTH callers
do", and the workflow's own preconditions are pinned by parsing the YAML rather than
substring-matching it — `head.sha` for `base.sha` is a nine-character diff.

Verified by mutation, six mutants, each killed by its intended test: ignore the exit
status; check out the head; drop `persist-credentials`; add `--expect`; re-inline a
`pulls/N/files?` fetch; delete the PROTECTED clause.

That last one initially MISSED, and the miss was the useful finding. The test used a
docs-only-plus-protected file list and passed with the clause deleted, because
PROTECTED (`.claude/ .gitea/ .husky/ scripts/ docker/ci/`) and DOCS_ONLY (`docs/`, root
`*.md`) are disjoint — on the docs-only path that clause can never fire, and DOCS_ONLY
was doing all the work. PROTECTED is load-bearing only on the BOT path, so the test now
covers a Renovate PR editing the shared script, with a positive control proving the bot
exemption fires at all.

The caller contract is tested by EXECUTING the workflow's `run:` block against a stubbed
enumeration that fails while emitting a perfectly docs-only list — the one combination
the "every failure path also happens to print nothing" redundancy cannot absorb, and the
exact mutation that survived the whole suite last round.

Docs: both "Landing note" blocks removed, and the record's base-ref paragraph converted
from a future-tense requirement to present-tense fact with its staging rationale kept as
history.

review-verdict/h10 Review-verdict: MERGEABLE @ b255b7f
Round 5 could not break the predicate itself: 28,930 real runs of the script across
14,465 crafted --version strings on bash 3.2.57 and 5.3.15 produced zero fail-opens, and
`{1,9}` is honoured on bash 3.2, so round 4's bound is not void on the authoring Macs.

What it did find is that two of round 4's changes were unpinned, and the tests that
looked like they covered them did not.

Reverting BOTH the first-line slice and `[[:blank:]]`→`[[:space:]]` together left the whole
suite green. The four filler cases are all killed by the SEPARATOR restriction alone, so
they attributed the fix to the wrong layer. Added three cases carrying the literal word
`version` (`jq\nversion\n9.9` and friends), which satisfy the separator rule and can only be
stopped by confining the parse to line one with a newline-free blank class.

The CR-strip test was worse: vacuous through two independent mechanisms. `str.splitlines()`
also splits on `\r`, so a per-line view dropped the stray CR; and `subprocess.run(text=True)`
translates `\r` to `\n` outright, so even a raw-string check on stdout was unfalsifiable.
The mutant demonstrably emits `... = jq-1.6<CR> (parsed 1.6; ...)` at the byte level while
the test reported green. Added `run_bytes()` and a bytes comparison.

Both gaps are now mutation-verified: reverting either change reddens exactly its own test.

Also records the operational edge this parser acquires in the follow-up: it is strictly
fail-closed by design, so once the floor mode gates the required check, a jq wrapper that
prints a banner line would deadlock merges. The fix there is to widen the accepted forms,
never to relax fail-closed.

timothy 4e094637c6 fix(648): the version parser was fail-OPEN on a jq that cannot start
Round 3, and it found that round 2's fix was a REGRESSION on the case that matters most.

`raw=$(jq --version 2>&1 || true)` did two wrong things at once: folded stderr into the
parse input and discarded the exit status. Combined with a pattern that matched the first
<digits>.<digits> ANYWHERE, a jq broken by a glibc mismatch — which exits 127 and writes
"version `GLIBC_2.34' not found" to stderr — parsed as version 2.34 and PASSED the floor.
The strip-based parse this replaced failed CLOSED there. So the fix for a fail-open bug
introduced a worse fail-open bug, in the one script whose entire purpose is to refuse to
certify a version it did not parse.

Same mechanism, second symptom: an unanchored match let a prefix outrank the real version.
`2026.07.26 jq-1.6` parsed as 2026.07; a leading warning line carrying any number won too.

Now: jq's exit status is captured explicitly (`$?` inside `if ! cmd` is the NEGATED status,
so that needed care too), stderr is kept out of the parse, and the pattern is anchored to
the leading `jq` token. Every legitimate form still parses — `jq-1.6`, `jq version 1.6`,
`jq-1.7.1`, `jq-1.6-dirty`, `jq-1.6 (Debian 1.6-2.1)`, `jq-1.10` (numeric compare, so the
two-digit minor is not read lexically).

The tests could not have caught any of this: the shim always exited 0 and never wrote to
stderr, so every case it could express was clean. It now takes stderr and an exit code, and
the four new cases turn red under the exact mutation.

Also: the drift guard now strips comment lines before matching. A future comment citing
`pulls/$pr/files?limit=100` as an example of what not to do would otherwise have reddened
script-tests — which, per this branch's own correction, blocks merges.

And the record no longer over-corrects: the combined-status read is guarded by
`if [ "$mwcs" != "true" ]`, so a red script-tests blocks the hook-mediated merge path, not
literally every merge.

Decisions-Edit: yes

timothy 5e7623b8d5 fix(648,649): security-review round 2 — close the version-parse hole and the untested caller contract
Two real defects, and three docs claims that were simply wrong.

jq-preflight.sh parsed the version by stripping around the first `-` and `.`, which
assumed the format is exactly `jq-X.Y`. A build printing `jq version 1.6` left major
empty; the sanity check concatenated major+minor into "6", which is non-empty and
all-digits, so it PASSED. The floor comparison then ran `[ "" -lt 1 ]`, which errors —
and `set -e` exempts a failing command in an `if` condition, so the conditional read
false and the script exited 0 having asserted nothing, after printing a plausible
"parsed" line. The silently-untested-axis failure this script exists to eliminate,
reproduced inside the script itself. Now parsed by explicit regex, failing closed with a
diagnosis when there is no <digits>.<digits> match. Also: `--expect` with no value exited
1 with empty output on both streams.

The hook's exit-status check was pinned by nothing: mutating `if files=$(...)` into
`files=$(...) || true; files_complete=yes` left the ENTIRE suite green. It survived only
by redundancy — the script writes stdout once, right before exit 0, so failures also
happen to yield empty stdout and `[ -n "$files" ]` catches it. Safe by accident, which is
the exact criticism this branch levels at the old code. Four tests now pin it, with a
stub that FAILS while emitting a docs-only list (the one case redundancy cannot absorb)
plus a positive control proving the harness can see the difference. Verified: the
mutation now turns exactly those tests red.

Docs corrections. The record claimed the --expect pin was safe because script-tests is
"advisory, not a required check" — false. The merge-consent hook reads the COMBINED
status (ci.advisory-red-blocks-the-merge-gate, #598), so firing the tripwire blocks every
non-docs-only merge until someone re-pins. Kept anyway, for a stated reason, but no
longer described as free. The record also asserted in the present tense that
review-verdict.yml checks out the base ref; it has no checkout step at all, so that is
now a future-tense requirement on the follow-up. And the documented .status allow-list
named GitHub's `removed`, which the code rejects.

The drift-guard regex anchored on `?limit=`, so a re-inlined copy written
`files?page=1&limit=50` would have walked past it.

timothy 2c10f057b8 fix(648,649): stage the enforced-gate wiring behind the scripts it calls
Splits the review-verdict.yml rewiring out of this PR. That workflow checks out the
PR's BASE ref — deliberately, so a PR cannot rewrite the gate that judges it — and the
base is main, which does not yet contain scripts/pr-changed-files.sh or
scripts/jq-preflight.sh. Wiring it here would make the job exit 127 on its own PR and
block the merge gate through the combined status, which reads red jobs as blocking.

So this PR lands the scripts, their tests, the hook rewiring and the script-tests jq
pin; the follow-up points review-verdict.yml at them once they exist on main.

The two tests that asserted on review-verdict.yml are scoped accordingly, each carrying
the reason. test_review_verdict_never_pins_a_jq_version is asserted NOW rather than in
the follow-up, so the no-pin constraint on the required check is already enforced when
the wiring lands.

timothy 63fa81fbb5 docs(648,649): the jq contract + the shared PR-file enumeration record
Adds docs/ci-cd.md "The jq contract" (1.6 floor, the three divergent constructs,
and the deliberate pin-vs-floor asymmetry with its merge-deadlock reason), plus two
decision records: ci.jq-version-contract and ci.shared-pr-file-enumeration.
ci.script-tests-job stops restating the three jq rules and points at the new record.

Also corrects the script-tests preflight description: it is now two steps (git
presence, then jq VERSION via scripts/jq-preflight.sh --expect 1.6), not one.

A literal NUL byte had crept into the ci-cd.md paragraph describing jq 1.6's NUL
truncation — which git treats as a binary file. Replaced with the literal text.

Round-4 review found the fall-through tests, while now falsifiable, still did
not pin the whole guard. Two gaps, both closed and both verified by running the
mutation rather than by asserting the test would catch it:

1. All three fall-through tests used only "   ", so narrowing
   IsNullOrWhiteSpace to `image == "   "` would have passed while breaking
   fall-through for null and "" -- and null is the form the API actually
   persists. Parameterized over null, "" and "   ".

2. Nothing pinned the guard's `ImageSource is Custom` clause. This is the
   sharper of the two: a ChannelLogo watermark's Image is NORMALLY blank
   (the API writes Image = null for every non-Custom source), so dropping the
   discriminator would send every playout-item ChannelLogo watermark down the
   fall-through path instead of resolving the channel's own logo -- with a
   fully green suite. Added
   Blank_Image_ChannelLogo_Playout_Item_Watermark_Should_Win_And_Not_Fall_Through,
   which distinguishes the two levels by watermark Id so a fall-through is
   observable even though both resolve to the same cached path.

Mutation results (each mutation applied on its own, then reverted):

  drop `is Custom` from the guard  -> 1 failure, and the new test is the ONLY
                                      test that catches it
  IsNullOrWhiteSpace -> == "   "   -> the null and "" parameterized cases fail

Negative control re-measured on the final 32-case fixture: 19 fail against the
origin/main resolver. The 13 that pass both ways pin deliberately preserved
behavior plus the positive control, which the record now states explicitly
along with the mutation table.

This round's lesson, recorded in the record: a test's NAME is not evidence it
pins what it claims, and a whole-file revert cannot show that a test aimed at a
specific clause actually reaches that clause -- only mutating the clause can.

Gates: 2661 tests green across 4 projects, 225/225 script tests (the gate I
skipped before the last push), decisions-validate OK, format exit 0, no BOMs.

CI's script-tests job (test_frontmatter_reader_matches_pyyaml_on_every_real_record)
caught that the dependency-free hand parser and PyYAML disagreed on this
record's `rule:` field.

Cause: `rule:` was an unquoted plain YAML scalar containing " #653)", and in a
plain scalar " #" starts a comment. PyYAML therefore truncated the value at
"...(the song-progress overlay," and silently dropped the rest of the clause --
including the scope carve-out naming #653, which is the whole point of that
sentence. The generated catalog row was built from the truncated value, so the
active-decisions view was quietly missing it.

Same trap as fix(631) (a record TITLE whose unquoted " #" was a comment). The
`signals:` and `mechanics:` fields were already single-quoted, which is why only
`rule:` diverged; `title:` is safe because its "(#510)" has no space before the
"#". Single-quoted `rule:` and regenerated the catalog, which now carries the
full sentence.

Worth recording: I ran scripts/decisions_validate.py locally but NOT
scripts/tests, so the gate that catches exactly this class was the one local
check I skipped. Touching the decisions corpus means running the pytest suite,
not just the validator -- the validator reads through the hand parser and so
cannot see a hand-parser-vs-PyYAML divergence by construction.

Local: 225/225 script tests pass, decisions-validate OK.

review-verdict/h10 Review-verdict: MERGEABLE @ daedf00
Addresses the round-3 cold re-review's five low-severity findings on #644's client-side paging fix:

- F1: `loadPickerOptions` (RerunCollectionsScreen, PlaylistsScreen) returned one `truncated:
  boolean` for two different conditions — a real Class B cap hit vs an unconverged Class A
  `loadAllPages` load — so an incomplete multi-collection load rendered the self-contradictory
  "Showing the first 47 of 47 — use search to narrow." Replaced with a `hint: 'incomplete' | 'none'
  | 'truncated'` discriminator and distinct copy per value; 'incomplete' matches the wording already
  used by the Class A list-load warn Badge.
- F2: mirrored the out-of-list current-selection injection (RerunCollectionsScreen/PlaylistsScreen's
  `selectedInList` prepend) into FillerPresetsScreen and ScheduleItemInspector's rerun-collection
  picker, so an id outside the loaded page still renders as selected instead of misrepresenting the
  stored value as "(none)".
- F3: gated the `console.warn` on an incomplete Class A load with `!signal?.aborted` in the `multi`
  branches (RerunCollectionsScreen, PlaylistsScreen) and SchedulesScreen.loadAllRerunCollections, so
  a superseded/aborted load (Retry, or a type switch mid-load) no longer logs a false warning.
- F4: added `Select`'s `ariaDescribedBy` prop and wired the truncation/incomplete hint span to it via
  `useId()` in RerunCollectionsScreen and PlaylistsScreen, so screen readers announce the hint
  (FillerPresetsScreen already routed it through `Row help=`).
- F5: added FillerPresetsScreen.test.tsx (previously untested) covering the Class B single-request
  guarantee, the truncation hint's totalCount>100/<=100 boundary, and the F2 injection; added the
  two assertions the re-review found missing anywhere in the suite — the Class A `incomplete` warn
  Badge actually rendering, and a screen-level seqRef stale-overwrite race — to
  RerunCollectionsScreen.test.tsx.

Updates docs/spa-conventions.md §3b and the
spa.list-completeness-vs-bounded-pickers decision record to describe the hint discriminator.

Re-review of the previous fix commit found that two tests added to close
round-1 findings could not fail. Both verified before fixing:

1. Missing_But_Named_Custom_Playout_Item_Watermark_Should_Not_Fall_Through
   gave the channel-level fallback the SAME missing custom path as the
   playout-item watermark, so a wrongly-widened guard would have fallen
   through to a fallback that also resolved to None -- the assertion held
   either way. The fallback is now an independently resolvable ChannelLogo
   whose cached file exists, so a fall-through returns it and fails the test.
   Added the matching positive control (blank -> falls through and DOES
   return that logo), so the pair shows the guard distinguishes blank from
   unresolvable instead of both landing on None.

2. Deco_With_One_Valid_And_One_Missing_Watermark... asserted a filtered list
   length while the routing claim the decision record cited it for lives in
   FFmpegLibraryProcessService.CanUseFFmpegNativeWatermark, which the test
   never called. It now calls the real predicate.

Also, three wrong claims of my own:

3. The Resource arm comment said "nothing in the app writes a Resource
   watermark to the database". False -- CreateWatermarkHandler and
   UpdateWatermarkHandler persist whatever ImageSource the request names, so
   a Resource watermark IS creatable through the API, always with
   Image = null. That is precisely why the new null guard is load-bearing,
   so the comment was arguing for its own removal.

4. "One resolver and no per-caller policy" contradicted the surviving
   playout-item blank-Custom fall-through documented a few lines later.
   Reworded in both the record and the XML docs: one resolver, and exactly
   one piece of per-caller policy which lives in the CALLER.

5. The record's "12 of 18 new tests fail pre-fix" was stale. Re-measured
   against the final fixture: 19 of 29. The other 10 pass both ways by
   design because they pin preserved behavior, which the record now says
   explicitly rather than leaving the gap to be read as weakness.

Removed the vacuous generated-URL test rather than keeping it with an honest
comment -- an empty list trivially contains no URL, so it implied coverage it
never had. Its assertion is folded into the sibling test that has a real
arrangement.

Gates: 2772 tests green across 5 projects, dotnet format exit 0, no BOMs,
decisions-validate OK, live-E2E re-run against this binary (0 changed pixels,
nameplate absent, warning emitted).

Build ErsatzTV Image / Build & push image (amd64) (pull_request) Has been skipped
Independent cold review (Codex, no implementation role) found no Blocker and
three real defects, all fixed here:

HIGH — HDR was re-tagged bt709 only when the profile had NormalizeColors on.
The colorspace filter sat behind desiredState.ColorsAreBt709, so an operator
with normalization disabled got tonemapped SDR pixels still tagged bt2020 and
the player converted them a second time. The guard is now
"tonemapped || (ColorsAreBt709 && ...)". Deliberately NOT fixed by hoisting
usesVppQsv out of the guard, which would force bt709 on scale-only non-HDR
chains that legitimately opted out.

MEDIUM — image subtitles stopped being resized. The subtitle canvas is scaled
only when the video chain contains a recognized scale filter, and that predicate
listed the QSV filters only; swapping ScaleQsvFilter for ScaleVaapiFilter left a
4K HDR + PGS source with a 720p video and a source-size subtitle overlay.
VaapiPipelineBuilder already listed ScaleVaapiFilter; QsvPipelineBuilder does now.

MEDIUM — anamorphic HDR now falls back to the software tonemap. ScaleQsvFilter
is handed the SAR VideoStream calculates (it has a 0:0 fallback); ScaleVaapiFilter
multiplies by ffmpeg's runtime `sar`, which differs when the decoded frame leaves
SAR unspecified. Rather than ship a graph nobody has run, exclude anamorphic --
which leaves those sources exactly where they were before this change.

LOW — tests now pin the exact validated graph as an ordered substring (the prior
assertions would have passed with setFormat off, hwdownload dropped, or the wrong
tonemap output format), assert against the vpp_qsv OPTION rather than a bare
"tonemap=1" substring, and cover NormalizeColors=false, anamorphic and image
subtitles. Each of the three fixes was negative-controlled: reverting it fails
exactly one test, and no others.

The remaining LOW (deriveDevice's defaulted bool is a future-call-site trap) is
recorded as an accepted residual rather than fixed, since a named factory would
push this diff into the VA-API pipeline for no behavior change.

The record is 86 prose lines, over the 60-line ceiling. Declining to cut: every
bullet is a distinct measured finding, which docs.corpus-size-signal names as a
legitimate decline.

timothy 1a7f15fb27 fix(510): address independent review — Resource null guard, honest routing claim
Two independent reviews (cross-family Codex + cold Opus) both returned
BLOCKED. Findings, all verified against source before acting:

1. Resource arm could throw ArgumentNullException (Codex, Medium). Making the
   channel/global Resource arm reachable exposed that CreateWatermarkHandler
   and UpdateWatermarkHandler write `Image = null` for EVERY non-Custom
   watermark, so an API-created Resource watermark reached
   Path.Combine(folder, null). Added the blank/null guard the arm never had.
   This was live at the playout-item level too, not just newly-reachable code.

2. "Routing is unaffected" was false (Codex, Low but sharp). The predicate is
   unchanged, but CanUseFFmpegNativeWatermark also tests Count == 1, and
   dropping an unresolvable watermark shortens the list. A deco with one valid
   and one missing permanent watermark now routes ffmpeg-native where it
   previously routed to the graphics engine. Intended, but observable -- so it
   is documented and pinned by a test rather than claimed away.

3. "Exactly one resolver" over-claimed (Opus, High). True of the selector, not
   the application: the song-progress overlay is built as a WatermarkOptions
   directly by the streaming and troubleshooting handlers, unchecked, and can
   still hand ffmpeg a nonexistent -i. Pre-existing; scoped the claim in the
   record and channels.md and filed #653.

4. Undeclared crash->degrade change (Opus, Medium). Channel/global Custom had
   no blank-image guard, so a cleared image hit ImageCache's fileName[..2] and
   threw out of stream startup. Now declared in the record and tested.

5. Contradictory rule text (Opus, Medium) -- the catalog one-liner said
   "always no bug" while the body documents the playout-item fall-through
   exception. Qualified; catalog regenerated.

6. History was wrong in both the record and the XML docs: the three precedence
   levels did NOT all check every source -- channel/global had no Resource arm
   and threw. Corrected.

Tests: 30 in the fixture now (was 18). New coverage for the preserved
blank-Custom fall-through (to channel AND to global), the complement case
(missing-but-named must NOT fall through), null/blank Resource, and the
valid+missing routing case. 17 of 24 failed against the pre-fix resolver
before this round; the fixture stays mutation-sensitive.

Also: hoisted the mock-filesystem Initialize() out of its loop so a
multi-file case cannot silently seed only the last file, and marked the

timothyandClaude Opus 5 94182cdd53 fix(644): split loadAllPages by list class; bound media-library pickers to one page
Cold adversarial review of fe342a6a found the blanket loadAllPages-everywhere fix
dangerous for the three getLibraryBrowseItems pickers (RerunCollectionsScreen,
PlaylistsScreen, FillerPresetsScreen): paging Episode/Song/Image/Movie/MusicVideo
to completeness can mean ~200 serial requests against a 20k-row library, each more
expensive than the last, to populate a <select> with thousands of <option> nodes.

- Class A (bounded-by-construction lists: rerun collections, multi-collections,
  playlists) keep loadAllPages. Class B (media-library pickers) now fetch ONE
  bounded page and surface truncation via a `Showing the first N of M` hint wired
  to the real totalCount, instead of paging to completeness or truncating silently.
- loadAllPages: reports `{ items, complete }` instead of just `T[]` so a caller
  can no longer mistake a defensive empty-page break for a full list (F4); accepts
  an optional AbortSignal so a superseded loop stops issuing further page requests
  (F2); baseParams is now required via a conditional rest-tuple whenever the
  loader's params type has a field beyond pageNum/pageSize (F6); pushes into the
  accumulator instead of re-spreading it every page (F7).
- MultiCollectionsScreen/RerunCollectionsScreen/SchedulesScreen: add a seqRef +
  AbortController guard around the list/bootstrap loads so a stale loadAllPages
  loop can't resolve after a newer one and resurrect deleted rows (F3); log and
  surface an incomplete load rather than rendering it as whole.
- docs/spa-conventions.md §3b rewritten for the Class A / Class B split; new
  decision record docs/decisions/records/spa/list-completeness-vs-bounded-pickers.md
  (spa.list-completeness-vs-bounded-pickers), catalog regenerated.
- Tests: paging.test.ts covers null/undefined totalCount, null page, a
  short-but-non-empty page, a page-2 rejection, the complete:false flag, and
  cancellation (asserting fetch call COUNT stays put after abort), plus a
  compile-time @ts-expect-error pinning the F6 typing fix. Screen-level tests
  pin a real second HTTP request for a >100-item Class A list
  (MultiCollectionsScreen) and exactly one /library/browse request plus the
  truncation hint for a Class B picker (RerunCollectionsScreen).

timothy 18c4f4e0b2 docs(505): correct the #498 record's escape-hatch claim, which was wrong the dangerous way
The qsv-decode-encode-split record told HDR-on-QSV users to set
QsvPreferNativeDecoder OFF "to keep GPU tonemap". Measured on the Intel host,
vpp_qsv=tonemap=1 is a silent no-op on pre-Gen11 graphics, so following that
advice did not preserve GPU tonemapping -- it disabled tonemapping entirely and
shipped untonemapped HDR.

Prose correction only; the decision itself (the QsvPreferNativeDecoder toggle)
is unchanged and stays active. The software-tonemap half of the bullet was
always accurate and stands.

Decisions-Edit: yes

timothy 41e2870113 fix(505): tonemap QSV HDR through OpenCL; vpp_qsv=tonemap is a silent no-op
#505 asked to route the #498 native-decode path through TonemapQsvFilter to
move HDR tonemapping off the CPU. Measured on the Intel host (jazz: FFmpeg
8.1.2 / iHD 25.1.4 / UHD 630) against real HDR HEVC Main10, that filter is a
SILENT no-op: a graph ending in vpp_qsv=tonemap=1 returns a frame byte-identical
(same md5) to the same graph with no tonemap at all, with no warning and no
error. QSV VPP tonemapping needs Gen11+; pre-Gen11 iHD ignores it.

So the issue's premise was inverted, and the branch it wanted to extend was
already broken: the existing DecoderHardwareAccelerationMode == Qsv path shipped
untonemapped HDR whenever QsvPreferNativeDecoder was off -- which is exactly the
escape hatch #498/#523 recommend. Prod was unaffected (native-decode is the
default and took the working software branch).

Tonemap on the GPU via OpenCL instead, the route VaapiPipelineBuilder already
uses and the one Jellyfin uses. The scale has to run first, in scale_vaapi:
tonemapping full-size is slower than the software path it replaces (15.5s wall
for 12.5s of content, below realtime), while scale-first cuts total CPU ~60%
(35.6s -> 14.1s) and lands at the no-tonemap wall-clock floor. A QSV surface
maps to neither OpenCL nor VA-API, so the gate requires software frames: the
QSV decoder and deinterlace_qsv both fall back to the software tonemap, slower
but correct. TonemapQsvFilter is deleted -- a filter that silently does nothing
is worse than no filter.

Also fixes output tagging: the first end-to-end run was correctly tonemapped yet
still announced bt2020 primaries, because SetPixelFormat's usesVppQsv predicate
("did a hardware filter strip color info") listed only the QSV filters. Both new
filters are now in it.

Validated end to end on jazz with the exact generated command: exit 0,
YAVG 26.39 (software reference 26.6, untonemapped 44.3), and ffprobe reports
bt709 space/transfer/primaries.

timothy 9cbe70e486 fix(510): one watermark resolver for all four attachment points
WatermarkSelector resolved watermarks in two places with two policies. The
three precedence levels (playout item, channel, global) existence-checked
every image source and degraded to None; the deco path had its own copy of
the same switch that returned whatever path it computed, unchecked. So one
channel could disagree with itself about whether an on-screen bug rendered,
based only on how the watermark was attached.

#502 deferred this here but scoped it to ChannelLogo. It was never
ChannelLogo-only: the deco path skipped the existence check for Custom and
Resource too. Extract one ResolveWatermark used by all four sites.

Severity is not cosmetic. A dead LOCAL path is not harmlessly skipped --
CanUseFFmpegNativeWatermark hands a single permanent watermark to ffmpeg as
a bare -i argument and excludes only URLs, so the deco path could hand
ffmpeg a nonexistent input file.

The generated-initials nameplate was real: a live-E2E on a real transcoded
frame confirmed it composited via the deco path (/iptv/logos/gen is on
ArtworkController, which has no auth filter, so the container-internal
self-fetch succeeded). The #502-era comment claiming "it has never rendered
here" was wrong, and the new record says so. It is still removed: serving it
means an HTTP fetch inside stream startup, which graphics.channel-logo-caching
(#525) eliminated for logos, and it depends on #1's hardcoded localhost.
Reviving it by caching the image instead is #652.

Measured blast radius on prod: 0 Deco rows, 0 DecoWatermark rows, all 43
channels have logo artwork -- no rendered output changes.

Preserved deliberately: a playout-item Custom watermark with a blank image
still falls THROUGH to the channel/global watermark; unifying resolution must
not change which watermark wins. Routing is untouched.

Strict improvement: the channel and global arms previously threw
NotSupportedException on a Resource watermark; they now resolve it. The
default arm still throws so a new image source fails loudly.

Tests: 18 new cases including a positive control and 8 deco-vs-channel parity
cases. 12 of the 18 fail against the pre-fix resolver, which is what proves
they are load-bearing rather than vacuous.

timothy fe342a6a0b fix(644): page SPA list loaders to completeness instead of inflating pageSize
Seven call sites (rerun-collections, multi-collections, library/browse) requested
pageSize far above each endpoint's server-side MaxPageSize=100 clamp and took the
single response page as the whole list, so rows past 100 silently vanished with no
error or truncation indicator.

Extract the loadAllRerunCollections pattern from SchedulesScreen (#634) into a
shared, generic web/src/api/paging.ts::loadAllPages helper that pages against
totalCount with an empty-page defensive break, and refactor SchedulesScreen plus
the seven over-cap call sites in RerunCollectionsScreen, MultiCollectionsScreen,
PlaylistsScreen, and FillerPresetsScreen to use it. Server caps are unchanged
(api.search-allitems-paging precedent: client pages, server stays bounded).

review-verdict/h10 Review-verdict: MERGEABLE @ fefd11d
Squashed from 7 commits (4 review rounds) to keep the rebase onto #621 tractable; the
full round-by-round history is on PR #642.

corpus was 5658/5600 — over budget and warning again — 3h35m after #619 put it at 5228,
with nobody consolidating anything.

So this does NOT re-baseline. An aggregate over a monotonically growing corpus can only
ratchet; that is the "permanently red, therefore no signal" state #542 re-baselined away
from, and growth is not even a smooth rate to plan against (the corpus FELL from 5089 to
5042 across four days, then gained 427 in one evening as two large records landed).

Replaces it with a per-record prose ceiling (default 60), non-blocking, naming each
record over it — not monotonic, so it can go red AND green, and it points at a file. The
aggregate is still printed as an unthresholded trend notice, with record prose and
non-record scaffolding reported separately because they are not the same unit. The
GENERATED catalog is no longer counted at all: it gains one row per record and no
consolidation can shrink it, which made the metric partly a record COUNT in a line-count
costume.

The calibration test took FOUR versions, and the failures are the durable lesson:
  v1  true by construction (`max(under) <= 60 < min(over)` over lists built by that test)
  v2  a gap WIDTH — a ceiling of 200 also sits in a wide gap, so it passed
  v3  fraction band + "clear air" vs the nearest record above — hostage to an unrelated
      record: one ordinary 62-line addition reddened it with the ceiling correctly
      placed, and the only remedy was to RAISE the ceiling. That is this very treadmill,
      as a hard failure in what #631 makes a blocking job.
  v4  `p90 <= ceiling <= p95` — the property stated directly and scale-free.
Two rules recorded: a guard test must depend only on the thing it guards, and a threshold
over a growing population must be expressed in that population's own terms.

Candidates: all over-ceiling records assessed, each actioned or declined with a reason.
The largest (scan.libraryfolder-unique-identity, 230 lines) is a legitimate DECLINE — a
dozen-odd distinct traps whose only copy that is. Nothing pruned, so no archive or
supersession was required. An automated redundancy metric is explicitly rejected.

Also: `--budget` is accepted but announces its retirement rather than no-opping silently;
the dead `budget_ok` parameter is gone; and five "untresholded" typos are fixed, one of
which was propagating into the generated catalog row and MemPalace's per-key drawer.

review-verdict/h10 Review-verdict: MERGEABLE @ 37fd30d
Third latent defect surfaced purely by running scripts/tests in CI — and this one was
already red on origin/main, where test_frontmatter_reader_matches_pyyaml_on_every_real_record
fails.

`api/paging-zero-based.md` carried an UNQUOTED plain scalar title ending
"... (#616, #633)". In YAML a space followed by `#` starts a COMMENT, so PyYAML reads the
title as truncated at "(#616," while the hand-written dependency-free reader keeps the
whole line. PyYAML is correct per spec; the record's title was genuinely losing "#633)"
for any spec-compliant consumer, which includes MemPalace's ingest.

Fixed by quoting the scalar; both parsers now agree byte-for-byte.

Asked "instance or class?" before fixing: swept every frontmatter field of all 179
records under both parsers and compared. This is the ONLY divergence in the corpus, so a
one-line fix is the right scope — no lint rule needed, and #621's structural guard
already makes a parse FAILURE loud (this was a parse-to-different, which no structural
check can see).

216 passed under jq 1.8.2 and jq 1.6.

timothyandClaude Opus 5 bb1809fbf0 fix(647): the jq-1.6 fail-open was ALSO in review-verdict.yml — the enforced gate
Round-4 review caught the miss that matters most: #643 fixed the `jq -e`-on-empty
fail-open in .claude/hooks/pretooluse-merge-consent.sh, but the SAME construct sits in
.gitea/workflows/review-verdict.yml — and that is the copy that runs on the CI runner,
where jq is 1.6, and that feeds the branch-protection-required review-verdict/h10
status.

Reproduced: `printf "" | jq -e '.statuses | type == "array"'` exits 4 on jq 1.8.2 (guard
fires, correct) and 0 on jq 1.6 (guard passes). So on a transient API error `statusjson`
is empty, the guard lets it through, `existing` reads "", and the job posts `pending` —
or for a bot/docs-only PR an exemption `success` — over a possibly-existing human
verdict. That is precisely what the comment three lines above it says must never happen.

The hook version was harmless in practice because it runs on a dev Mac with jq 1.8. This
one is live. Fixed identically, with a comment naming why the sibling fix missed it, and
the same hardening applied to the changed-files read in the same workflow.

Also from round 4:

- LOW, reproduced — an ARRAY-valued `.status` dodged the closed allow-list. `index` is
  polymorphic: with an array argument it does SUBSEQUENCE matching, so
  `[...,"renamed",...] | index(["renamed"])` is truthy while `.status == "renamed"` is
  false — the row passed the allow-list AND skipped the `previous_filename REQUIRED`
  clause. The same `git mv code -> docs/` dodge the closed set exists to block, one type
  away. Now requires `.status` to be a string first; mutation-verified.

- The record now carries all THREE jq rules rather than the one, and notes that the
  durable fix is pinning/preflighting the runner's jq version rather than patching
  constructs one at a time (tracked on #647).

200 tests pass under BOTH jq 1.8.2 and jq 1.6.

timothyandClaude Opus 5 f4473926d4 fix(643): close the status-string dodge, pin the allow-list anchors, fix two doc claims
Round-3 review (MERGEABLE, all findings Low/Nit) — applied anyway, because each is the
over-claim or unpinned-anchor family this PR keeps hitting.

LOW — the `renamed => previous_filename REQUIRED` clause matched `.status` by exact
lowercase string, so any other value took the `else true` branch: a row with
`"Renamed"`, or with no status at all, validated fine and silently dropped its SOURCE
path, letting `git mv ErsatzTV/Program.cs -> docs/a.md` read as docs-only. `.status` is
now checked against a closed set and an unknown value fails closed.

Two things that fix taught me, both caught by my own positive control rather than by
review:
  1. The first predicate was WRONG in a way that gated everything: inside
     `[...] | index(.status)`, jq's `.` is the ARRAY, so `.status` was null and every
     row failed. `$s` is now bound from the row before the context switches. A
     security check that rejects everything looks identical to a working one from the
     failing side — only test_gitea_real_status_values_are_accepted caught it.
  2. The set includes BOTH `changed` and `modified`. Live Gitea 1.25.4 emits `changed`,
     but a closed allow-list built from the wrong vocabulary is worse than the hole it
     closes: it would gate every genuine docs-only PR. The property wanted is "reject
     what we don't recognise", not "enumerate one version exactly".

LOW — three allow-list anchors had no test at all: dropping `^` from the `docs/`
alternative (`ErsatzTV/docs/Program.cs` would exempt), dropping `$` from `.md`
(`x.md.cs` would exempt), and dropping the non-empty-list guard. Since the round-3 `..`
finding WAS an anchor subversion, they are now pinned; all three mutation-verified.

NIT — docs/ci-cd.md called this job "a checkout plus a pure-stdlib pytest run", which
the same file contradicts 450 lines later and which this PR's own record names as the
bug that turned the job red on its first CI run. Also replaced a frozen "111 tests" with
an explicitly indicative figure — the suite is ~190 after rebasing onto main, and a
frozen count has rotted four times this session.

198 passed under both jq 1.8.2 and jq 1.6.

timothy 54c875414c fix(643): validate every field the extraction consumes; fix a vacuous test
Re-review of the previous fix commit found it incomplete and its test vacuous. Both
reproduced before fixing.

MEDIUM — the validation domain did not match the CONSUMPTION domain. `chunk` emits
`(.previous_filename // empty)` for EVERY row regardless of status, but the guard
validated that field only when `.status == "renamed"`. So a row marked `modified` — or
Gitea's distinct `copied` — carrying a newline in previous_filename was still exempted.
Verified EXEMPT for both statuses against the previous commit. Now validated whenever
present, with the `renamed` => REQUIRED clause kept on top.

MEDIUM — test_newline_in_previous_filename_is_also_rejected asserted the right outcome
without exercising the mechanism: its payload's second segment was
`ErsatzTV/Program.cs`, which the allow-list rejects on its own, so the test passed with
the newline guard entirely removed. That is why the hole above went unnoticed — the
same filter-hides-the-defect trap the guard itself is about. Payload changed to a
segment that PASSES the allow-list, so the test now discriminates, plus parametrized
regressions for modified/copied/added.

LOW — `..` components rejected. The allow-list anchors `^docs/`, so
`docs/../ErsatzTV/Program.cs` matched it (reproduced). Git will not produce such a
path, but this guard exists to fail closed on unexpected 2xx shapes.

Added a positive control (a legitimate docs->docs rename still exempts) so the
tightened row schema cannot be satisfied by never exempting anything.

Severity calibrated in the record: the docs-only exemption ends in `decide allow ""`, a
passthrough to the normal permission prompt, NOT an auto-grant. Every bypass here
downgrades a mechanical deny/ask to a human prompt; none can silently self-merge. Real,
worth fixing, but not what an earlier framing of #643 implied.

timothy c046add10a fix(643): close two more fail-opens in the docs-only enumeration, found by cold review
An independent cross-family review of the jq-1.6 fix found two further ways the
docs-only exemption can fire over an incomplete file list — both reachable with NO
transport error, so neither had anything to do with the original bug.

1. HIGH — a path containing a newline. `chunk` flattens paths into newline-delimited
   text before the allow-list grep, so a filename of "safe.md\ndocs/Program.cs" splits
   into two lines that BOTH match the allow-list, while the real single path ends in
   .cs. Git permits newlines in filenames and the reviewer reproduced the bypass
   against this hook. Now rejected outright at the row-schema guard, on both
   `filename` and `previous_filename`: no docs path contains a control character, so
   failing closed costs nothing.

2. HIGH — a short page read as the last page. `n < 50` assumed the server's page size
   is the 50 we requested, but Gitea caps `limit` at the server-wide
   MAX_RESPONSE_ITEMS (default 50, configurable) and may return fewer. A 30-row docs
   page followed by a page of code completed the enumeration over a PARTIAL list.
   Only a validated EMPTY page may now terminate it; the page<=40 cap still fails
   closed, and the cost is one extra request.

3. MEDIUM — the enumeration was not bound to one head. Paging is several round-trips,
   so a force-push between them assembles a list belonging to no single commit: page 1
   from head A plus a short docs tail from head B, with B's code page never read. The
   head sha is re-read after enumeration and the exemption refused if it moved.

All three mutation-verified: reverting each fix reddens exactly its own test and
nothing else. A positive control (short page then empty page) pins that the stricter
terminator still exempts a genuinely docs-only PR, so "never terminate early" cannot
be satisfied by never exempting anything. 118 passed under BOTH jq 1.8.2 and jq 1.6.

The record now states the generalisable lesson: every defect here was an
exhaustiveness failure in an enumeration whose completeness is load-bearing. When a
security decision depends on having seen ALL of something, the termination condition
must be positive and explicit, never inferred from a proxy.

timothy 5f068a2488 fix(631): close a fail-open in the merge-consent gate that only CI could see
Running scripts/tests in CI for the first time turned up a real defect in the gate
itself, not just in the harness.

`jq -e` over EMPTY input exits 4 on jq >= 1.7 but 0 on jq 1.6 — verified against both
binaries, not inferred. The docs-only pagination guard in
pretooluse-merge-consent.sh leaned on that exit status to reject a transport failure.
On jq 1.6, which the CI runner ships:

  page 2 errors -> gq returns empty -> jq guard wrongly PASSES -> n is empty so
  [ "$n" -lt 50 ] errors into false -> the loop walks PAST the failed page -> page 3
  legitimately returns [] -> files_complete=yes over a PARTIAL list -> the docs-only
  exemption fires over unread pages that may be pure code.

That is the very defect the guard's own comment describes, reintroduced one layer down
by a jq version difference. Fixed by rejecting an empty body explicitly rather than
inferring it from jq's exit status. The same hardening is applied to the
review-verdict status read, which fell through to `vstate=""` -> deny (fail-CLOSED, so
never a hole) but would have surfaced the wrong message.

Why it survived: the existing transport-failure test asserts the right thing but can
only observe the bug where jq is 1.6, so it passes on a developer Mac with the bug
fully present — and the suite had never run anywhere else. The new test removes that
dependency by shimming ONLY jq 1.6's empty-input exit status, so it pins the property
on any host. Mutation-verified: revert the fix and it goes red on jq 1.8.2.

The shim is deliberately narrow (no `-n`): a broader first version swallowed the
`jq -n` calls `decide` uses to build its JSON, so the hook emitted nothing and every
decision read as a passthrough — the verifier manufacturing the exemption it was
meant to disprove. test_jq16_shim_actually_reproduces_the_quirk now pins the shim
itself, `-n` case included.

Suite: 113 passed under jq 1.8.2 AND under jq 1.6.

timothy 73577f484f ci(631): install pyyaml too — the suite is not pure-stdlib, and CI proved it
First CI run went red on `ModuleNotFoundError: No module named 'yaml'` at collection:
test_migration_equivalence.py imports scripts/migrate_decisions_split.py, which uses
PyYAML by design. It passed locally only because this machine already had PyYAML.

The original claim came from reading decisions_lib/decisions_validate/build_catalog
and the test files themselves — which is precisely the set that does NOT import yaml.
Replaced with an AST import scan over all of scripts/, which gives the complete
third-party set: pytest and yaml. (etv_client is imported only by
scripts/scripted-schedules/entrypoint.py, a container entrypoint pytest never
collects.)

This does not contradict the dependency-free decisions READ path:
decisions_lib._read_frontmatter is hand-written exactly so validation runs where
nothing is installed. The one-shot WRITE path is allowed PyYAML, and its test needs it.

Verified the way it should have been the first time: a clean venv with pytest alone
reproduces CI's collection error; adding pyyaml gives 111 passed. Comments, ci-cd.md
and the decision record all corrected to drop the "pure stdlib" claim.

decisions-guard runs decisions_validate.py and build_decisions_catalog.py directly
(the code, never its tests) and the `test` job is dotnet test only. The 111 tests
guarding the decision corpus, the #610 migration-equivalence harness, the
merge-consent exemption logic and the #622 review-verdict poster were enforced only
by whoever remembered to run pytest locally.

Adds a `script-tests` job to pr-checks.yml rather than the step inside decisions-guard
the issue proposed. decisions-guard is covered by ci.decisions-lifecycle-flake, a
standing instruction that a lone `decisions lifecycle` red is a known flake and must
not be investigated — so a genuine pytest regression there would surface as exactly
the red every session is told to wave through. A gate inherits the credibility of the
job it lives in.

Runs unconditionally: the suite executes the real post-review-verdict.sh and
pretooluse-merge-consent.sh, so a `scripts/**` path filter would miss a
.claude/hooks/** edit. ~10s, pure stdlib + pytest.

Negative control verified locally (broken test -> exit 1); CI-red measurement follows
on a scratch PR per the Done-when.

The record said "10 tests go red"; on the rebased base a full short-circuit reddens 11.
Both numbers are real and measure different mutations: neutering only the scan loop
leaves the empty-wing check live (10), while returning [] from the whole function
disables that too (11). The reviewer flagged the phrasing as ambiguous before the count
also drifted.

Now states the mutation alongside the number, since a bare count is exactly the kind of
frozen figure this session has watched rot four times.

Re-review found the basename exemption was not actually removed: the code still dropped
any wing-root README.md, and the docstring defended that with "no such file exists
today; the catalog README lives in TOPIC_DIR". That is false — docs/decisions/archive/
README.md exists and parses to []. So the rule text in the record, the catalog row and
ci-cd.md all asserted something the shipped code contradicted.

It was also a live hole, not just wrong prose: dl.active_files() globs RECORDS_DIR.rglob
with NO filter, so a future docs/decisions/records/README.md would be a corpus source
while exempt from the guard — verbatim the hole this PR cites as the reason to stop
using _NON_DECISION_FILES, reintroduced one directory over.

Now exempt by exact RELATIVE PATH ({archive/README.md}), with a test pinning that the
same basename in the ACTIVE wing is still faulted. Mutation-verified.

DISAGREEING with one review finding, deliberately. It asked for the empty-wing
anti-vacuity check to be symmetric across both wings. The semantics differ: zero ACTIVE
records means the scan measured nothing and any clean result is vacuous, while zero
ARCHIVED records is a normal state — nothing superseded yet, true of any young repo and
every fresh clone before the first supersession. Making it symmetric fails a correct
corpus (it reddened 7 tests). The asymmetry stays, with the reason in the code and a
test pinning it so nobody "fixes" it back.

127 passed.

timothy 98b3e8715b fix(621): close three exemption holes and pin the guard's own wiring, per cold review
An independent cold-context review found the guard could be disabled or bypassed in
four ways, one of them silently.

HIGH — the guard's only wiring was untested. Deleting `wing_faults=record_wing_faults()`
from main() left the ENTIRE suite green (120 passed) while a real block-scalar record
vanished again with `decisions-validate: OK`. Every existing test either called the
collector directly or handed validate() a hand-built list, so nothing pinned that
main() ever invokes it — the #609 "prints OK while doing nothing" defect, one level up,
inside the fix for that same defect. Independently reproduced before fixing. Now pinned
by a monkeypatched sentinel test.

MEDIUM — a record could escape by BASENAME. `_NON_DECISION_FILES` is a set of TOPIC-dir
names ({README, migration-map, retrieval-eval}) and was applied to the wings too, so a
genuine record at records/docs/retrieval-eval.md was skipped. Not hypothetical: the
path<->key rule forces key `docs.retrieval-eval` to that exact filename, and
dl.active_files() applies that filter only to the TOPIC_DIR glob — so the file would be
a corpus source while exempt from the guard. Now nothing is exempt by basename.

MEDIUM — the archive exemption was by LOCATION but justified by IDENTITY. Anything
directly in archive/ was skipped, so a new unparseable archive/foo.md would vanish in
the one directory left unwatched. Now exempt only if it really is a #610 stripped index:
one keyless record with a known generated heading.

LOW — parse-to-WRONG. `rule: >-` with an UNINDENTED continuation containing a colon
parses to one VALID keyed record whose rule is literally ">-", plus a junk key, silently
truncating the real value. PyYAML rejects that input, so the hand reader is more
permissive than the writer. Now faulted via an unknown-frontmatter-key check.

LOW — an absent or empty wing reported clean. Now loud: refusing to certify a corpus
from a scan of nothing.

Doc corrections, all measured rather than asserted: "all 167 records use single quoted
lines" was false (117 of 168 rule: values are unquoted plain scalars — the invariant is
single-LINE); the archive shape in the record, ci-cd.md and the rule: field said
`archive/<area>/` where the code deliberately uses archive/** ; the mutation count is 10,
not five; and the "converts ANY reader limitation" claim is softened to the class it
actually covers.

125 passed.

timothy 0f565b1f7e fix(621): make an unparseable decision record loud instead of silently invisible
A file under the record wings that the dependency-free frontmatter reader cannot
parse returned [] and simply vanished from the corpus: decisions_validate.py printed
OK, build_decisions_catalog.py --check said "up to date", the record was absent, and
nothing anywhere errored. Reproduced end-to-end with a YAML block scalar (`rule: >-`),
which is the natural thing to reach for on this corpus's very long rule: values and
which parsed fine under PyYAML before #610's dependency-free reader.

An EXISTING record disappearing was already loud (the no-vanish diff check). The hole
was a NEWLY ADDED record, which that check structurally cannot see — no base state to
diff against — so the author's own PR looks clean. Hence a per-PATH check, not a
per-construct or diff-driven one: asserting "this path yields exactly one keyed
record" turns any present or future reader limitation from silent to loud in one move.

Adds record_wing_files/record_wing_faults to decisions_validate.py, surfaced through
validate() as ERRORS (a file in the record wings that is not a record is a mistake by
definition) and reported first, since a file that failed to parse leaves every
downstream check silently evaluating an incomplete corpus. The five top-level stripped
legacy archive files are exempt — they are generated "Records formerly in this file"
indexes, keyless by construction, and are what keeps older date-based pointers
resolvable.

_read_frontmatter is deliberately NOT extended to accept block scalars; rationale in
the new docs.record-wing-parse-guard record.

8 tests, mutation-verified: with the check neutered 5 go red, restored all 119 pass.
A live-corpus positive control asserts the wings are non-empty so a clean result can
never be vacuous.

timothy 214fad2dcd fix(633): document the 0-based paging contract on the OpenAPI parameters
`api.paging-zero-based` says `pageNum` is 0-based across `/api/v1` and every wrapper
of it. That was true of the MCP tool catalog and the docs, and not true of the
generated OpenAPI document: all 24 paging parameters across the 12 paged operations
were emitted with no `description` at all, so a consumer reading only `v1.json` — the
intended contract, and what generated clients surface to their users — had to infer
the base from `default: 0`. That is the same inference that cost #487 a verification
pass on the MCP side, where the description was present but wrong.

Annotates each `[FromQuery]` paging parameter with `[Description]`
(`System.ComponentModel`), the mechanism `parentId` already used in ImagesController,
and regenerates `v1.json`. `pageSize` states the endpoint's OWN cap, because the caps
genuinely differ — 100 typical, 200 auto-tune members, 1000 search/all-items — and the
record forbids documenting one global number; it also states that the offset derives
from the effective (capped) size, so an over-large `pageSize` narrows the page instead
of widening the offset.

The generated TypeScript client covers DTOs only, not query parameters, so it is
unchanged; `endpoint-index.md` carries summaries, not parameter descriptions, so it is
unchanged too.

Pinned by OpenApiPagingContractTests against the in-process generated document. The
test NAMES the expected set of 12 paged operations rather than only filtering for
parameters called `pageNum`: a filter cannot see an endpoint that should page and
doesn't, which is exactly how two MCP tools escaped the equivalent check in #616. Set
equality is asserted in both directions, and the caps are pinned per endpoint so a
description naming the wrong cap fails — a wrong justification outlives a wrong line.

Mutation-verified both ways: dropping one `[Description]` reddens the description test,
and making one endpoint stop exposing `pageNum`/`pageSize` under those names reddens
the set-equality test.

Round 5: raw HTML is the third code-block form. `<pre>`, `<code>` and HTML comments all render their
contents literally, so a verdict inside one is an example, not an approval:

  <pre> / <code> / <!-- ... -->  containing a verdict  ->  positive

Now stripped, tracked as a marker count rather than parsed — the direction of error is to strip MORE,
which can only ever withhold approval. Mutation-verified: removing the stripper fails all five cases.

AND THE HARDENING STOPS HERE, deliberately. The record now says so, because otherwise the next
session re-derives it: this is a best-effort heuristic, not a markdown parser. It covers the three
code-block forms markdown has (fenced; indented, via the column-0 rule; raw HTML) and is not proof
against every way to render text as non-prose.

Stopping is safe because the comment is NOT the load-bearing gate. Since #622 the authoritative
signal is the `review-verdict/h10` commit status, written only by post-review-verdict.sh from
explicit arguments — a comment cannot forge it. This classifier is condition (c) of the PreToolUse
hook: defense in depth on an agent's merge call. A residual false-open means the hook does not
object; it does not mean a merge happens.

Five rounds found five code-block forms, four of them introduced while fixing the previous round.
The generalisable rule, now in the record: when a heuristic keeps failing at the edges, check whether
it is actually the thing enforcing the invariant before spending another round on it.

Also measured, against the real corpus: a "verdict must be the first line" rule would have killed
every code-block form at once, but 14 of 18 verdict markers ever posted in this repo are NOT on the
first line — so it was rejected as a retroactive break, not deferred.

Round 4 found the last false-open: markdown has a SECOND code-block form the fence stripper does
not cover — indented blocks (4 spaces or a tab). A pasted indented example still self-approved:

    Example:

        Review-verdict: MERGEABLE @ <head>     ->  positive

Adding an indented-code stripper would be the same move that produced rounds 2, 3 and 4: fixing the
instance, not the class. So the grammar is narrowed instead — the marker must sit at COLUMN 0. That
kills every indentation-based ambiguity at once (4-space, tab, list-nested, arbitrary indent).

Cost, accepted deliberately: a verdict indented under a list item is now ignored and classifies
`absent`, which asks a human. For a gate, erring toward ignoring is the safe direction. Fence
detection KEEPS its leading-whitespace tolerance, because stripping more is always safe.

`test_leading_indent_is_tolerated` asserted the old behaviour and is replaced by
`test_falseopen_an_indented_verdict_is_not_a_verdict`, parameterised over four indent shapes and
mutation-verified: restoring `^[[:space:]]*` fails all four, control green. 172 tests.

Round 4 verified clean by execution: the rc plumbing fails closed for a forced failure in the inner
jq, awk, grep AND the pipeline producer (rc 3/4/5/93 -> exit 2); fence-length semantics, mismatched
markers, CRLF fences, 10-marker fences, blockquote fences; emoji, CRLF, a 120k line, 200 comments;
NUL rejection with no JSON-encoding bypass.

Third review round, third set of real findings. Both reproduced before fixing.

1. High: markdown closes a fence only with N-or-more of the SAME marker it was opened with, so a
   ```` block legitimately CONTAINS a ``` line as content. Toggling on any 3+ marker left the
   fence at that inner line and graded the verdict below it as a real approval:

     ````text / ``` / Review-verdict: MERGEABLE @ <head> / ````   ->  positive

   Now tracks the opening marker's character and length; a shorter or different marker while a
   fence is open is content, so it neither closes the fence nor escapes it.

2. Medium: `awk ... | grep ... || true` flattened "no match" (grep rc 1, normal) together with a
   real tool failure (rc >= 2). A failing reader produced no verdict lines at all — `absent` —
   silently discarding a real BLOCKED verdict. awk and grep are now checked separately, and only
   "no match" is tolerated.

Also fixed while writing (2): `[ rc = 0 ] && printf` as the loop body's LAST command would leave
the subshell exiting 1 whenever the newest comment carried no verdict, which the rc check would
then report as a failure to read comment bodies — an ordinary PR reading as broken. Uses an `if`.

169 tests. Both findings mutation-verified: restoring the naive fence toggle fails all four
longer-fence cases, restoring `|| true` fails the failing-grep case, control green. Verified the
ordinary shapes still work: plain ``` and ~~~ fences and lang-tagged fences still stripped, an
unclosed fence still swallows, a real verdict beside a fenced example still counts, and a fenced
positive alongside a real BLOCKED still classifies negative.

timothyandClaude Opus 5 f151b93245 fix(629): review fixes — tilde fences, an unbounded sha field, and a forgeable comment boundary
Cross-family review of 38a96f47 returned BLOCKED with three findings. All reproduced first:

  ~~~ fence           -> positive   fences were stripped for ``` only; markdown also takes ~~~
  @ <40hex>f / ZZZ    -> positive   the sha matched {7,40} with NO right boundary, so an
                                    over-long or malformed token was TRUNCATED into a passing one
  \x01BODY-BOUNDARY\x01 -> positive an in-band separator joined comment bodies, so a body
                                    containing that line forged a boundary, reset fence state
                                    mid-comment, and exposed a verdict inside an unclosed fence

Fixes: both fence markers honoured; the hex run matched whole, required to end at a
non-alphanumeric boundary, with its length validated separately so an out-of-range token is
rejected rather than trimmed to fit; and bodies carried OUT-OF-BAND (one JSON-encoded string
per line), which removes the forgery class instead of escaping the sentinel.

The third is the one worth remembering: an in-band delimiter is forgeable by whoever writes the
data, and here that is anyone who can comment on the PR.

Two of these fixes broke previously-green tests, both of which were right to break:
- an over-long token now classifies `no-sha`, not `stale`. The fixture asserting `stale` was 45
  hex chars, so it had been exercising the length guard while claiming to test the prefix rule.
  Rebuilt as a well-formed 40-char sha that contains the head prefix without starting with it.
- `jq -e` exits 4 when a filter produces NO output, which is the legitimate empty-comment-list
  case. Treating it as an error turned "no comments yet" into an input error — and callers fail
  closed on those, so a new PR would have read as unclassifiable. Exit 4 is now accepted.

44 classifier tests, 155 total. `~~~` and the boundary fixes are each mutation-verified; the
out-of-band fix has no equivalent mutation (it is structural, not a regex) so its evidence is the
direct reproduction against the previous commit.
