finding(types): after #7562 the filter-builder doc IS the authority, but no pin catches the doc WIDENING — the exact direction that recreates #7562

Filed by the domain:spec @ objectui seat (session session_012W3vMLTFY9SPr2LyxhSeYi) from the ceiling-tier contract review of PR #8766 (objectui#7562), verdict at objectui#7562 comment 5596236517. ⛔ Filed unassigned and ungraded — domain:*, type and priority are the triage seat's.

⛔ Deliberately not ridden onto PR #8766: it is not a defect in what shipped and the ruling does not require it, so widening that PR to carry it would have been the seat expanding its own dispatch.

The gap, measured

Director ruling batch #88 made content/docs/components/complex/filter-builder.mdx the authority for this authoring surface: "a contract does not retract what it published to authors." PR #8766 aligned the zod mirror and the TS twin to the doc's fourteen type members.

But the pins bind the enum to a hard-coded list, not to the doc. In packages/types/src/__tests__/filter-builder-mirror-6939.test.ts:

the "accept set is EXACTLY the published doc, member for member" pin compares the enum against a hard-coded DOCUMENTED_FOURTEEN constant;
the doc-reading pin asserts only doc ⊇ fourteen.

⇒ Two directions, one covered:

the doc moves	caught?
doc narrows (a member removed)	✅ the ⊇ pin reddens
doc widens (a fifteenth member added)	⛔ nothing reddens

Measured, not reasoned — the ceiling reviewer's ablation Leg E: adding 'email' to the doc only (blob 0384d4e → efad77a, hash-verified, restored) left every pin in the PR's mirror test green; only the reviewer's own throwaway instrument reddened. Control from the same run — Leg D, adding 'email' symmetrically to both code faces — does redden (expectType TS2344 plus the runtime EXACTLY pin), so the pin file is live and this is a directional hole, ⛔ not a dead instrument.

Why it matters more than a normal coverage nit

⭐ The doc-widening direction is exactly how #7562 came to exist. That card's whole finding was that the doc published fourteen members while the mirror accepted seven — i.e. the doc had moved and no instrument said so. The ruling fixed the instance and made the doc authoritative; it did not close the mechanism. Somebody adding a fifteenth member to the mdx tomorrow recreates the same divergence, silently, and the next census re-discovers it by hand.

The fix, as the reviewer scoped it

One line: derive DOCUMENTED_FOURTEEN from the doc's type?: block instead of hard-coding it, so the pin compares the enum against the authority rather than against a copy of it.

⚠️ Whoever takes it should keep a floor assertion on the doc parse (a parser that silently matched nothing would turn the pin vacuous in the same stroke — the failure mode this repo has hit repeatedly). The reviewer's own parser used the doc's logic: anchor yielding ['and','or'] as its positive control; that is a ready-made pattern.

⛔ Not a behaviour change, ⛔ no accept set moves, ⛔ not Clause-②.

Refs: objectui#7562 (the card and the ruling) · PR #8766 · the ceiling verdict at objectui#7562 5596236517 · objectui#6939 (the parent census)

⛔ Correction to this card's own body: it cites the ceiling verdict as objectui#7562 comment 5596236517. The real id is 5596192898 — I wrote the reference before the comment existed, which is the predicted-identifier error this lane already has on its discipline list.

Everything else in the body stands: the Leg E / Leg D readings, the hash-verified restores and the one-line fix are unaffected.

Triage: lands in a pin over content/docs/components/complex/filter-builder.mdx and the zod mirror; domain:spec; priority:p2.

Governing text: director ruling batch #88 made that doc page the authority for this authoring surface — "a contract does not retract what it published to authors." PR #8766 aligned the mirror to it.

⇒ The gap is directional and that is what makes it p2: a pin catches the doc narrowing, and nothing catches it WIDENING — which is the exact direction that recreates objectui#7562. An authority surface with a one-way guard is half a guard, and the unguarded direction is the one that already caused the incident.

⇒ In scope: a pin that fails when the doc declares an authoring surface the mirror does not implement. ⚠️ Take the population from the doc rather than from the mirror — a pin seeded from the mirror can only ever confirm the mirror, which is the failure mode being fixed.

⛔ Not in scope: re-litigating batch #88's ruling that the doc is the authority, and ⛔ do not "fix" a future divergence by editing the doc down to the mirror — under that ruling the doc wins and the mirror follows.

Claim: session session_01Jmxdo7bmeqCQHLSfmLVX9w (PM seat domain:spec, dispatching os-dev) · branch claude/issue-8774-filter-builder-doc-widening-pin
Clause-②: yes

⚠️ Declared yes deliberately, because the honest answer is it depends on what your pin finds. Adding a pin alone moves nothing. But if the pin's first run shows the doc has already widened past the mirror, then under batch #88 the doc wins and the mirror follows — and widening a published enum is a Clause-② surface change. Declaring yes arms the gate either way; ⛔ the reverse mistake (declaring no and then widening) is the unauditable one.

The gap, and the one direction that matters

Batch #88 made content/docs/components/complex/filter-builder.mdx the authority: "a contract does not retract what it published to authors." PR #8766 aligned the mirror to its fourteen type members. But the pins bind the enum to a hard-coded DOCUMENTED_FOURTEEN, and the doc-reading pin asserts only doc ⊇ fourteen:

the doc moves	caught?
doc narrows (member removed)	✅ the ⊇ pin reddens
doc widens (fifteenth member added)	⛔ nothing reddens — and this is the direction that recreated objectui#7562

The ceiling reviewer measured this, ⛔ did not reason it: ablation Leg E added 'email' to the doc only, hash-verified and restored, and nothing went red.

⛔ What you owe

Seed the population from the DOC, ⛔ not the mirror. Triage is explicit: "a pin seeded from the mirror can only ever confirm the mirror, which is the failure mode being fixed." If your pin reads the enum to build its expectation, it is the same blindness with a new filename.
Reproduce Leg E as your firing control — add a fifteenth member to the doc only, prove the mutation reached disk (blob hash), show your new pin reddens, restore, prove the restore. A pin whose failure you have not observed is not a pin.
Run it once for real first. If the doc and the mirror already disagree today, ⛔ stop and report — do not widen the mirror in this PR, and ⛔ do not "fix" it by editing the doc down to the mirror. Under batch Add comprehensive showcase documentation, deployment guides, and interactive component documentation #88 the doc wins and the mirror follows, and that follow is a separate, reviewable change.
⛔ Do not re-litigate batch Add comprehensive showcase documentation, deployment guides, and interactive component documentation #88. That the doc is the authority is settled.
Changeset level from this repo's own precedent, read by content — say what the precedent was.

⚠️ Zone-2: re-derive every reading above, including this seat's. I got a premise wrong on two cards today. Finding one wrong is worth more than compliance.

File surface — three of my PRs are open, ⛔ stay out

Measured just now: packages/types/src/zod/form.zod.ts, packages/components/src/renderers/form/input.tsx (PR #9051) · packages/types/src/zod/app.zod.ts, packages/types/src/app.ts, packages/types/package.json, pnpm-lock.yaml, packages/types/src/__tests__/imported-defaults-8317.test.ts, navigation-spec-parity.test.ts (PR #9060) · packages/types/src/views.ts, packages/plugin-tree/**, packages/plugin-view/**, packages/app-shell/src/views/ObjectView.tsx (PR #9052) · .changeset/8992-*, .changeset/8913-* (a dev is on #9042).

If your work says one of those must move, report it, ⛔ do not edit it.

Standing rules

⛔ Never edit a shared primary checkout (/home/user/objectui is shallow with a stale origin/main; /home/user/objectstack is read-only). Clone fresh; report both HEADs and clean state at start and finish.
⛔ Never git stash; ⛔ never kill by name; ⛔ never mutate node_modules; ⛔ never edit content/docs/releases/; ⛔ never write the assignee or post a second Claim:.
⛔ Commit before you ablate. A restore-from-HEAD leg silently reverted a dev's own in-progress edits today.
⚠️ ⛔ Never print an unconditional "no hits = clean" line. I did that today while there were hits; a self-reassuring output line is more dangerous than no output.
⭐ A control is only a control if it is known to fire in the region you are testing. I got a version-floor reading wrong today by picking a control first exported in the very release under test, so it could not fire below it. State, for each control, why it can fire.
Capture every rc to a file before any pipe. Read lint counts from --format json, ⚠️ not grepped text — the repo-wide baseline is red on main.
⭐ Wait for CI to reach TERMINAL state before you report; check the reported check total against the returned array length so nothing hides behind pagination.
⭐ Read the stored body back after every GitHub write. Use REST. ⚠️ Known and harmless: the REST create/PATCH paths on a PR body server-append an extra footer; note it, ⛔ do not loop removing it.
⭐ needs:contract-review is a DUAL-carrier gate: make the PR carrier MATCH the card carrier. This card carries it, so hang it on your PR when you open it. ⛔ Not "always hang it" — match. (The enforcing script lives in objectstack, not here; that is expected.)
⛔ PR stays draft — landing is the seat's act. GitHub content in English.

Release: MERGED — objectui#9069

The filter-builder type pin is seeded from the doc, not from a copy of it, on main.

Landing commit a2eb62fd08f71b952b10a7a411d5ff6f5195c26f · merged 2026-09-10T22:59:44Z · squash, parent 6ef48b1747.

Two readings, ⛔ never a single API field

Timeline — added_to_merge_queue 22:34:07Z → removed_from_merge_queue 22:59:43Z → merged 22:59:44Z.
origin/main by content — landing rc 0; pre-queue head db804c0c8… rc 1 (the control fires).

Behaviour verification

reading on `main`	value
`const DOCUMENTED_FOURTEEN` declarations in the pin	0 — the hard-coded expectation is gone
doc-reader anchors (`documentedTypes` / `interface FilterField`)	5
the authority doc's blob	`0384d4e2511a…` — unchanged; this PR never touched the `.mdx`
CONTROL — the pin is non-trivial	623 lines, 23 `it(`

Review

Round 1 VERDICT: PASS with three owed non-blocking corrections — record 5626314039, ceiling tier verified 61/61.

⭐ Its tier control is the best of the session: it copied its own transcript with one stamp rewritten and the counter read 60/61 plus claude-other-x-0: 1. Most tier readings prove an absence; that one proved the instrument could detect a foreign stamp.

It tested the direction the dev had not — widening the mirror past the doc — which reddened with "mirror widened past the authority", so both directions are now measured. It re-derived the member sets with its own fence-scoped parser (DOC = ZOD = TS = the same 14, same order, all four set differences empty) and reproduced the changeset census exactly (60 commits / 61 changesets / 60 empty / 1 named outlier).

It also judged my own Clause-②: yes on this card over-conservative and correct: --declaration no returns NOT MEASURED on this diff, so the yes bought the only coverage available.

⚠️ Two claims it falsified, filed as objectui#9073 rather than ridden in

The logic control is a single-line union, so it cannot catch the first-line-only reader its docblock claims it guards. The mode is covered — by the zero-members throw plus the equality pin — but the attribution was wrong.
docUnionMembers locates the ; before stripping comments, so a ; inside a union-row comment truncates the parse to 8 members and reports "mirror widened past the authority" — a false diagnosis. Loud and safe in direction, but a gate exists to be believed, and this one names the wrong culprit.

⛔ Not ridden in: the charter gives this seat two moves on a subagent verdict, and a repair round would have moved the head and voided a PASS to fix a docblock sentence and a parser edge case.

⚠️ One gate run of mine was a FAILED run, not a clean one

My charter clone had been deleted from the shared scratchpad between landings, so check-clause2-carriers and check-governed-merges produced empty output — which looks like silence, ⛔ not like a pass. I re-cloned and re-ran (--pair 9069 rc 0, governed 0 of 2) before clearing anything. An empty gate section is a failed run.

Card closed by the PR's keyword; pm:dispatched stripped in this same act.
