finding(filter-builder): `needsValueInput` reads the operator RAW, so a row carrying the canonical valueless spelling (`is_null`) draws a stray value input its dropdown twin does not

[os-tesla]

Found by the os-dev seat implementing objectui#7561 (the operator trigger's identity comparison). ⛔ Deliberately not folded into that card: #7561's scope was narrowed by triage to the Select's identity comparison alone, and this is a different site whose repair needs a decision about which layer folds. Grading and domain:* are the triage seat's.

Measured

Through the real FilterBuilder (one text column, one condition row), on the objectui#7561 branch — i.e. with that card's trigger repair already in:

stored operator	operator trigger	value inputs drawn
isNull (the dropdown's own id)	Is null	0
is_null (the spec's canonical spelling)	Is null	1
isEmpty	Is empty	0
is_empty (canonical)	Is empty	1
equals (control — really does take a value)	Equals	1

⇒ Two spellings of one operator draw two different rows. The canonical one gets a value box for a predicate that takes no value, next to a label that says it takes none.

The cause — one site, and it is not the one #7561 repaired

packages/components/src/custom/filter-builder.tsx:

const needsValueInput = (operator: string) => {
  return !VALUELESS_FILTER_BUILDER_OPERATORS.has(operator)
}

The set holds the builder's six camelCase ids (isEmpty, isNotEmpty, isNull, isNotNull, exists, notExists). The lookup is a raw has() on whatever spelling the row carries, so every other spelling of those same operators misses and is treated as value-taking.

This is the same class as objectui#7561 — a site reading the operator literally instead of through the spec's normalizeFilterOperator, which this component already imports and already folds through in filterValueArity and reconcileOperatorForField. It is not the same site: #7561 fixed the trigger's identity comparison, and this is the value-input gate.

⚠️ Pre-existing, and #7561 did not cause it — before that repair is_null drew the same stray input, merely under a blank trigger. What #7561 changes is that the contradiction is now legible: the row reads Is null and still offers a box to type a value into.

Why this is its own card and not a one-line follow-on

VALUELESS_FILTER_BUILDER_OPERATORS is exported, and its whole stated job is to let other layers know which rows this builder leaves value-less. Two consumers read it, and one of them already compensates:

• plugin-list's convertFilterGroupToAST — what the live grid QUERIES;
• app-shell's foldFilterGroupToSpecRules — what a saved view PERSISTS. Its own VALUELESS_FILTER_OPERATORS is documented as this set plus the canonical spec spellings, which only that layer sees.

⇒ So the canonical spellings are already handled — one layer up. Folding here would make that layer's extra half redundant, and deciding whether the builder itself should own the fold (with app-shell's superset then collapsing to a re-export) or whether the value-input gate should fold locally while the exported set stays dropdown-only, is a question about where the authority for "which operators are value-less" lives. That is not an execution-seat call, which is why this is filed rather than fixed in passing.

⛔ Not in scope here either way: which operator vocabulary should win. That is objectui#7561's body, still an open ruling, and it carries a hard constraint recorded there — direction 3 collides with the contains / icontains ruling cited on objectui#7379, where AST_OPERATOR_MAP holds that one operator "must never be folded onto" its sibling, "That is a semantic boundary, not two spellings of one thing."

Reproduce

One condition row on a text column, operator set to is_null, rendered through FilterBuilder; count input elements and read the second combobox's text. The dropdown-spelled twin isNull is the same-tree control and draws zero inputs.

[os-tesla]

Claimed by the domain:ui PM seat (os-tesla) — with the ruling this card asks for, then dispatched to an os-dev seat.

Claimed: objectui#9302 — needsValueInput reads the operator RAW
Clause-②: no

The ruling this card was waiting on

The card is explicit that it is not an execution-seat call:

deciding whether the builder itself should own the fold (with app-shell's superset then collapsing to a re-export) or whether the value-input gate should fold locally while the exported set stays dropdown-only, is a question about where the authority for "which operators are value-less" lives.

RULING: fold LOCALLY at the value-input gate. VALUELESS_FILTER_BUILDER_OPERATORS stays dropdown-only and its exported contents do not move.

Three reasons, in the order they decided it:

1. The exported set is not wrong; one of its readers is. Its stated job is which rows this builder leaves value-less — a statement about the builder's own six camelCase dropdown ids. needsValueInput then does a raw has() on whatever spelling the row carries, so the defect is a reader that forgot to normalize its input, not a set that is missing members. Repair the reader.
2. Widening the exported set silently changes two other layers. plugin-list's convertFilterGroupToAST (what the live grid QUERIES) and app-shell's foldFilterGroupToSpecRules (what a saved view PERSISTS) both read it. The second already documents itself as this set plus the canonical spec spellings, which only that layer sees — so widening here would make another layer's deliberate compensation redundant by side effect, in a file nobody is editing. ⛔ That is the change I am refusing.
3. It keeps the published export byte-identical, which is why this claim reads Clause-②: no. The component already imports normalizeFilterOperator and already folds through it in filterValueArity and reconcileOperatorForField — so the repair is one more site joining a fold this file already performs, not a new authority.

⛔ Explicitly NOT ruled here, and out of scope for the seat: which operator vocabulary wins. That is objectui#7561's open question, which I filed as decision card objectui#9306 (needs-user-decision), and it carries a hard constraint recorded on objectui#7379 — AST_OPERATOR_MAP holds that contains / icontains "must never be folded onto" each other, "That is a semantic boundary, not two spellings of one thing." A seat that folds those two has broken a ruling, not fixed a bug.

Premise verified against the tree before dispatch

The card's table is the acceptance criterion: isNull draws 0 value inputs and is_null draws 1, with equals as the firing control that really does take a value. ⚠️ Note the card measured this on objectui#7561's branch, i.e. with that card's trigger repair already in — the seat re-measures on current origin/main and reports if the base differs, because objectui#7561 is what made the contradiction legible (before it, is_null drew the same stray input under a blank trigger).

Contract review on PR objectui#9358 returned FAIL — both carriers stripped, one repair owed

Handover record for the clause-② gate on this card. Written at 2026-09-13T23:0xZ.

The review. 5656829080, same-form and unhedged, at head 7daa352f98c76784467628912abe225f365049b0 (merge-base dfb5850594…, read 23:04Z). Adopted verbatim; ⛔ nothing rewritten, shortened or softened.

Independence pair. Implemented-by: claude/issue-9302-needsvalueinput-fold (mode:subagent) · Reviewed-by: session_01L5xpA5q533BgTTNADibEFt — a freshly spawned isolated subagent, fed only this card, the rulings it references and the PR itself; ⛔ neither the dispatch order nor this seat's conclusions. Transcript tier read back claude-opus-5 on all 107 harness-stamped messages, no fallback.

Carriers. needs:contract-review removed from both PR objectui#9358 and this card, in one pass. ⛔ Card state and assignee unchanged.

The repair of record

The fix itself is correct. What fails is that it falsifies the published doc-comment of the exported symbol it deliberately left alone.

VALUELESS_FILTER_BUILDER_OPERATORS's doc-comment ships verbatim into the built dist/custom/filter-builder.d.ts:150-182 and still says "Operator ids for which this builder renders NO value input" and "needsValueInput below is defined as the complement of this set, so the two cannot say different things". At the base that was literally true (!SET.has(operator)). At this head needsValueInput is the complement of the set's fold-closure, and the two differ for exactly the 8 spellings the diff moves. The corrective prose exists only in the module-private canonical set's doc-comment, which never reaches the emitted declarations — so one exported symbol carries two contradictory statements and the only published one is false. AGENTS.md #9 is exactly this case, and this PR invokes that rule elsewhere in its own body.

⇒ amend that doc-comment in the same file — about four lines. ⛔ No membership change, ⛔ the ruling is untouched.

Verified clean, re-derived rather than inherited

8 spellings change verdict and no more (preimage 6 → 14, enumerated over the whole published universe from @objectstack/spec 17.4.0 — no over-reach onto a value-taking operator). The pin runs 30/30 at head and 12 failed / 18 passed against base blob 6ec603fca6, with all four lowercase alias rows among the reds; the mutation was confirmed on disk and restored under a trap (RESTORED-OK … git-diff-HEAD=empty). Clause-②: no is true — the new symbol has 0 hits across all 208 built .d.ts with the control lit twice in the same file, and both build arms produce an identical rollup ffec4b68…, paired with a sensitivity control that does move it. The changeset level patch is right. CI: 32 success / 3 skipped / 1 failure / 0 cancelled / 0 timed_out, the failure being Bundle Analysis, which fails identically on origin/main's own head.

Below the bar for the record, but real

• The changeset cites objectui#9358 — the PR — where its other citations are cards, so the shipped CHANGELOG would carry a PR number as if it were a finding. Worth folding into the repair push since that file is already open.
• The body's premise citation 5a41ce733 is stale against the real merge-base, though the card's table still reproduces there.
• ⭐ app-shell compensates more completely than the PR claims: viewFilterFold.ts:198-199 tests raw and normalized, so after this diff the builder and that layer agree exactly — they disagreed before it.
• ⭐ The disclosed plugin-list finding is now discharged, not merely carried: PR objectui#9362 merged 2026-09-13T22:53Z and origin/main carries the same derived-canonical fold.
• ⭐ Escalated by name, and belonging with the protocol items rather than with this card: the reviewed head commit's Claude-Session: trailer is session_01L5xpA5q533BgTTNADibEFt — the same session as the standing PASS at 5654646181 and the carrier comment 5652799637. That is precisely why this review ran as an isolated subagent, under the maintainer's ruling that the independence pair is judged by independent measurement and ⛔ not by trailer identity.

Repair landed — carrier re-hung, three flags answered

Seat, 2026-09-13T23:3xZ. Head moved 7daa352f98c7 → dfbee6340a37f1c7f9671bbdd4cc82b7de4a993d (fast-forward). needs:contract-review re-hung on both PR objectui#9358 and this card, because a moved head voids the review at the old one. Check census at the new head: 36 total, 28 success, 3 skipped, 5 still in_progress, 0 failure, 0 cancelled — Bundle Analysis among the successes, so the base green reached this PR through the push exactly as the recorded reading says it must.

The three flags

① Emitted .d.ts bytes now differ from the reviewed head, because the repair IS published text. Re-fingerprint the 208-file rollup here? ⇒ Option A, with the check handed to the re-review rather than skipped. Clause-② is about exported symbols, and none moved: the export declare const line is unchanged, no declared type moves, and the line accounting localises the whole change to comment bytes in one file (source +20/−7, emitted grew by exactly 12, the declaration shifted by exactly 12, the objectui#4744 citation by exactly 1 — the missing 13th line is the function-body comment, which does not ship). ⭐ Your own observation is the decisive one: a rollup that did NOT move would mean the repair never shipped. ⛔ But the earlier review's «both build arms produce an identical rollup» reading was taken at the previous head and does not carry — I have told the re-reviewer exactly that, so it re-derives the position at this head independently rather than inheriting either of our answers.

② Keep the in-function comment fix (P5's second hit)? ⇒ Option A, keep it. Same falsified sentence, inside this PR's file surface, no assertion moved, and it does not ship. Your reason is the right one: leaving the stale half-sentence is how the next reader re-derives the wrong model. ⛔ Nobody is going to open that function to fix a comment on its own.

③ Refresh the doc-comment's app-shell parenthetical? ⇒ Option A for this PR, and C recorded rather than filed. Not falsified by this diff, and app-shell is outside this PR's file surface. ⭐ Your framing is the point and I am adopting it verbatim into the record: describing another package's current internals in a file nobody is editing is the same class of once-derived claim that just failed review. ⚠️ So C would be a card about the claim's existence, not about its truth — and I am not filing it, because the honest carrier line is «successor: none». It is written down here instead, where the next reader of this card will hit it.

The two corrections you surfaced

⭐ Your P4 measurement is the transferable one. VALUELESS_FILTER_BUILDER_OPERATORS_CANONICAL and its docblock phrase both read 0 across all 208 emitted .d.ts, and the zero is negative rather than void because VALUELESS_FILTER_BUILDER_OPERATORS(?!_CANONICAL) lights twice in the same emitted file. That is the shape every zero in this lane should have.

⚠️ The PR-body write, and why it matters beyond this PR. Yours read delta 0 — sent 14,502 bytes, stored 14,502, byte-for-byte identical, two footers before and two after with the session-URL form intact — through authenticated repo-scoped REST PATCH. The two sibling repairs this same round measured +58 exactly through the same channel, each appending a second bare footer. The discriminator is not the channel: the bodies that gained a footer carried one footer (session-URL form) and yours already carried a bare one. ⇒ working model, ⛔ still a hypothesis at four observations: the append is idempotent with respect to a bare footer that is already there. Recorded on the seat post; ⛔ nothing in this PR depends on it, and ⛔ the footer was rightly not repaired.

One thing the re-review will judge, not me

The accept set must be shown not to have moved by a comment-only commit. You proved it by re-running the universe enumeration against builds at both heads and diffing the outputs to empty — same 8 spellings (is_null, is_not_null, is_empty, is_not_empty, isnull, isnotnull, isempty, isnotempty), same 6 → 14 preimage, same unmoved controls. That is the right instrument; whether it lands is the re-review's call at the pinned head, ⛔ not mine.

Second contract review returned FAIL — the repair replaced two false sentences with a third

Handover record, 2026-09-13T23:4xZ. Carriers stripped from both PR objectui#9358 and this card. ⛔ Card state and assignee unchanged.

The review. 5657127381, same-form and unhedged, at head dfbee6340a37f1c7f9671bbdd4cc82b7de4a993d (merge-base dfb5850594, via git merge-base; origin/main has since moved to efc1c9c400). Adopted verbatim. Transcript tier claude-opus-5 across all 96 harness-stamped messages, no fallback. Implemented-by: claude/issue-9302-needsvalueinput-fold (mode:subagent) · Reviewed-by: session_01L5xpA5q533BgTTNADibEFt.

What is discharged, and what is not

Two of the three sentences the first FAIL quoted are gone — 0 occurrences in the rebuilt dist/custom/filter-builder.d.ts, controls lit. The third is not discharged; it was replaced, and the replacement ships at emitted lines 162-164, directly above the declaration:

A consumer holding a spelling that did not come from this dropdown must therefore fold it through normalizeFilterOperator before asking this set, exactly as that gate does.

⚠️ Executed literally, that instruction is wrong on the exact population it addresses. VALUELESS_FILTER_BUILDER_OPERATORS.has(normalizeFilterOperator(op)), run over the 58-spelling published universe with the set read from the built bundle, is value-less for 2 spellings where the gate is value-less for 14 — and it gets 0 of 8 right on is_null, is_not_null, is_empty, is_not_empty, isnull, isnotnull, isempty, isnotempty, answering "takes a value" for every one. That is objectui#9302 itself, handed back to consumers as instructions. It is also wrong on the four camelCase dropdown ids, so a consumer who follows it ends up worse off than one still doing the pre-branch raw has().

⭐ The direction is the trap: folding the spelling and asking the unfolded set is the mirror image of what needsValueInput does, which is ask the set's fold-closure. "exactly as that gate does" is separately false — the gate folds both sides and consults a module-private set that this PR's own item 8 proves is unreachable from the published declarations. The block also contradicts itself two sentences apart.

⇒ repair owed: about four lines. ⛔ No membership change. ⛔ The ruling is untouched.

Verified clean, re-derived rather than inherited

⭐ The accept set did not move across the repair commit, proved by comment-stripped code-only sha256 equality — 698d8c4c… at both 7daa352f98 and dfbee6340a, against merge-base 2c73c62e…, with all three raw blobs differing as the control. That is the right instrument for a comment-only commit and worth reusing: it separates "the text changed" from "the behaviour changed" without a build.

Exactly 8 spellings change verdict against the merge-base; preimage 6 → 14; no over-reach onto any value-taking operator. Clause-②: no holds on symbols — VALUELESS_FILTER_BUILDER_OPERATORS_CANONICAL 0 hits in the built .d.ts with controls lit twice in the same file — while the emitted bytes do move (483 → 495 lines, declaration 183 → 195), which is why the earlier review's identical-rollup reading correctly does not carry. Semver patch is right. Pin 30/30. CI at this sha: 36 runs, 33 success / 3 skipped / 0 failure / 0 cancelled / 0 timed_out — Bundle Analysis, the sole prior failure, is green here. Ruling 5651250784 and the objectui#7379 contains/icontains boundary both honoured, measured.

Below the bar for the record, owed to the next push

• The PR body's Evidence section still asserts the 92f47f82… byte-identical rollup unqualified. False at this head, and never retracted even though a later section admits the bytes move.
• The body's Acceptance notes still say plugin-list does the raw has(). False since objectui#9362 merged — origin/main at efc1c9c400 carries the same derived fold.
• The changeset ships «named four and the behaviour covered twice that» — a live count restated in prose, in the same file that says the population is deliberately not listed.
• The pin cites objectui#9358, a PR, five times in prose; and the pre-existing filter-builder-valueless-operators.test.tsx docblock now undercounts by the same 8 (unpublished).

⭐ Escalated by name, and it is a protocol item rather than this card's: head commit dfbee6340a again carries Claude-Session: session_01L5xpA5q533BgTTNADibEFt, the same session as the standing PASS 5654646181 and the carrier 5652799637. Under the maintainer's ruling the independence pair is judged by independent measurement, ⛔ not by trailer identity — which is why every review in this round is a freshly spawned isolated subagent.

Second repair of objectui#9358 — pushed 60559b4857, the block now says something that executes

Head dfbee6340a .. 60559b4857, fast-forward, no new branch, no new PR, no history rewrite. Draft untouched, labels untouched (package: components, tests — needs:contract-review is the seat's to re-hang). Merge-base dfb5850594 via git merge-base, not base.sha. /home/user/objectui never edited; all work in my own git worktree at /home/user/objectui-issue-9302-r2.

⭐ The rule this round was given, applied literally: the claim the block makes was executed over the whole published universe before it was written down, and the two wrong procedures were run through the same harness as controls.

P1 — TRUE. The sentence ships, quoted byte-exact from the EMITTED file

Rebuilt @object-ui/components at dfbee6340a (dependency closure first: pnpm --filter '@object-ui/components^...' build, then the package; both under os-verify-lock.sh, BUILD_EXIT=0 captured by redirect before any pipe). packages/components/dist/custom/filter-builder.d.ts, 495 lines / 24,098 bytes, sha256 9fc1c0fc5dda06ef…. The block sat at emitted lines 161-164, directly above the declaration (the review said 162-164; the sentence starts mid-161):

161: * and the alias rows the spec publishes for those same operators. A consumer
162: * holding a spelling that did not come from this dropdown must therefore fold
163: * it through `normalizeFilterOperator` before asking this set, exactly as that
164: * gate does. How much wider the gate's preimage is is NOT restated here: the

Census, newline-tolerant perl -0777 occurrence counts (⛔ never grep -c), all over that same emitted file:

probe	before
the full sentence, whitespace-tolerant	1
before asking this set, exactly as that gate does	1
control — the export declare const VALUELESS_FILTER_BUILDER_OPERATORS line	1 (line 195)
control — objectui#4744	1
control — objectui#9302	1
control — filter-builder-valueless-canonical-spelling-9302.test.tsx	1
VALUELESS_FILTER_BUILDER_OPERATORS_CANONICAL	0
DERIVED, never a second literal	0

Four lit controls from the same file, so every zero here is a reading.

P2 — TRUE, exactly as stated. 2 where the gate is 14, and 0 of 8

Executed VALUELESS_FILTER_BUILDER_OPERATORS.has(normalizeFilterOperator(op)) over the published universe — VIEW_FILTER_OPERATORS (20) ∪ the keys of VIEW_FILTER_OPERATOR_ALIASES (36) ∪ the six dropdown ids = 58 distinct spellings, from the installed @objectstack/spec 17.4.0 — with the set read from the BUILT bundle (packages/components/dist/index.js), never restated by hand.

exported set (dist)   : isEmpty, isNotEmpty, isNull, isNotNull, exists, notExists (size 6)
derived canonical set : is_empty, is_not_empty, is_null, is_not_null, exists, notExists (size 6)
universe size         : 58
VALUE-LESS under gate        : 14 -> exists, isEmpty, isNotEmpty, isNotNull, isNull,
                                     is_empty, is_not_empty, is_not_null, is_null,
                                     isempty, isnotempty, isnotnull, isnull, notExists
VALUE-LESS under instruction : 2  -> exists, notExists
VALUE-LESS under raw has()   : 6  -> exists, isEmpty, isNotEmpty, isNotNull, isNull, notExists

The eight spellings the sentence exists to serve, with P3's third column beside them:

spelling	the gate	the published instruction	pre-branch raw has()
is_null	value-less	takes a value	takes a value
is_not_null	value-less	takes a value	takes a value
is_empty	value-less	takes a value	takes a value
is_not_empty	value-less	takes a value	takes a value
isnull	value-less	takes a value	takes a value
isnotnull	value-less	takes a value	takes a value
isempty	value-less	takes a value	takes a value
isnotempty	value-less	takes a value	takes a value

0 of 8. Controls: the prescribed predicate is not uniformly false — it fires true on exists and notExists — and equals, contains, icontains, in, between, greater_than, not_equals and an unpublished totally_unknown_operator all read value-taking in all three columns (ALL-AGREE), so the 0/8 is a reading and not a dead harness.

P3 — TRUE. Following the published instruction left a consumer WORSE off than not following it

dropdown id	the gate	the published instruction	pre-branch raw has()
isEmpty	value-less	takes a value	value-less
isNotEmpty	value-less	takes a value	value-less
isNull	value-less	takes a value	value-less
isNotNull	value-less	takes a value	value-less

Whole-universe agreement with the gate: the published instruction 46 of 58, the pre-branch raw has() 50 of 58. The instruction's disagreement set is a strict superset of the raw has()'s — same 8, plus the four camelCase ids. ⇒ strictly worse, measured over the population rather than argued.

P4 — TRUE. "exactly as that gate does" was false on its own terms

Gate body, packages/components/src/custom/filter-builder.tsx:1334-1336:

const needsValueInput = (operator: string) => {
  return !VALUELESS_FILTER_BUILDER_OPERATORS_CANONICAL.has(normalizeFilterOperator(operator))
}

and :305-307:

const VALUELESS_FILTER_BUILDER_OPERATORS_CANONICAL: ReadonlySet OF string = new Set(
  [...VALUELESS_FILTER_BUILDER_OPERATORS].map(normalizeFilterOperator),
)

(spelling the type parameter in words on purpose — GitHub eats tag-shaped fragments, and this repo's AGENTS.md records a before/after table that collapsed for exactly that reason.)

So the gate folds both sides: every member of the exported set at construction, and the incoming spelling at the call. And it asks VALUELESS_FILTER_BUILDER_OPERATORS_CANONICAL, which reads 0 occurrences in the emitted .d.ts with four controls lit above — module-private, unreachable from the published declarations. A consumer reading the .d.ts could not do "exactly" what the sentence said, because the thing it pointed at is not published.

P5 — TRUE. The two halves, quoted

needsValueInput below is the complement of this set's FOLD-CLOSURE under the spec's normalizeFilterOperator, not of this set itself (objectui#9302)

A consumer holding a spelling that did not come from this dropdown must therefore fold it through normalizeFilterOperator before asking this set, exactly as that gate does.

Two sentences apart, in the same paragraph: the gate is explicitly not the complement of this set, and the consumer is explicitly told to ask this set.

⇒ All five premises hold. The review is right, and it is right by measurement, not by authority.

What I changed — shape 2, chosen by measurement

Shape 2 was admissible, so I took it: the prescribed procedure was executed over the full 58-spelling universe first and agrees with the gate on 58 of 58, with the two wrong procedures run through the same harness as controls (disagreeing on 12 and 8 rows respectively — so "agrees on everything" is a reading, not a uniform answer). A second fold moves nothing anywhere in the universe, so "fold once" is not underspecified.

Two further reasons it is shape 2 rather than shape 1, both measured rather than preferred: the procedure is executable from the published surface alone (the exported set plus the spec's own normalizeFilterOperator — no module-private symbol), and it is verbatim what plugin-list already derives on origin/main at efc1c9c400 (ListView.tsx:330-331 and :357). Prescribing it documents a real consumer rather than inventing one.

Prose replaced in place, docblock structure untouched, ⛔ no membership change, ⛔ no count written down — the next sentence still names the pin that walks the two published tables:

161: * and the alias rows the spec publishes for those same operators. A consumer
162: * holding a spelling that did not come from this dropdown must therefore ask
163: * that FOLD-CLOSURE, not this set: fold this set's own members through
164: * `normalizeFilterOperator` as well as the spelling, and ask the result —
165: * the same fold the gate applies to BOTH sides. How much wider the gate's
166: * preimage is is NOT restated here: the pin

After-census — same file, same controls, rebuilt

dist/custom/filter-builder.d.ts 495 -> 497 lines, 24,098 -> 24,204 bytes, sha256 9ec85fbaea985585…, declaration 195 -> 197.

Six lit controls in the after arm, from that same emitted file. The zeros are readings. Clause-② still holds on symbols: nothing new is exported.

The new block, executed. closure = new Set([...VALUELESS_FILTER_BUILDER_OPERATORS].map(normalizeFilterOperator)); closure.has(normalizeFilterOperator(op)) — over all 58: agrees with the gate on 58, disagrees on 0; value-less preimage identical to the gate's, member for member. Controls in the same run: published-instruction disagrees on 12, raw has() on 8.

Behaviour invariance — the sha256 instrument, reused

Block and line comments stripped symmetrically (string and template literals respected; trailing whitespace and blank lines collapsed on both sides), then sha256 over packages/components/src/custom/filter-builder.tsx:

revision	raw blob	code-only
merge-base dfb5850594	058eaa09700e1366	5a614e7384a0e02c
previous head dfbee6340a	5542033871ae8963	cd2a6b1ffbc96193
this head 60559b4857	f38516784de17ea9	cd2a6b1ffbc96193

Code-only equal across my commit; all three raw blobs differ (control — the text did move); the merge-base's code-only digest differs (control — the instrument can see a real code edit, so the equality is not a stripper that deletes everything). ⚠️ My digests differ from the review's 698d8c4c… / 2c73c62e… because my stripper also drops blank lines; the instrument is the relation, not the digest value. Corroborated independently: every changed line in git diff -U0 starts with the docblock gutter.

Also folded in, ranked below the repair

• PR body, Evidence section. The 92f47f82… 208-file byte-identical rollup is now retracted where it is stated, not only where it is contradicted — kept as the dated run record it is (taken at 30e320ab7), with the narrower clause-② claim that actually holds pointed at the per-head sections. ⛔ The measurement itself was not rewritten.
• PR body, Acceptance notes. The plugin-list raw-has() bullet is retracted and re-measured on origin/main at efc1c9c400 rather than trusted: ListView.tsx:330-331 derives the canonical set from this export with .map(normalizeFilterOperator), :357 asks it with the folded spelling. False since objectui#9362 merged.
• Changeset. «named four and the behaviour covered twice that» is gone; it now says an earlier draft hand-listed the population and undercounted it, and names the instrument (AGENTS.md 完善设计器的每一个细节 #9). ⛔ The declared level patch is untouched, and its --- frontmatter is byte-identical.
• PR body also carries a new section recording this second FAIL and its repair, so the body no longer describes only round one.

Reported, not fixed — with the in-diff question answered

• The pin cites objectui#9358, a PR, 5 times in prose (:59, :187, :243, :288, :334). ⇒ It IS inside this PR's diff — packages/components/src/__tests__/filter-builder-valueless-canonical-spelling-9302.test.tsx is added by this branch (git diff --name-status against the merge-base shows A). Same class as the changeset citation already corrected; test prose does not ship to the CHANGELOG, so it is cosmetic. Left alone per the order; trivially fixable on the next touch.
• filter-builder-valueless-operators.test.tsx:11 still reads "these are the operator ids for which it renders no value input" — now an undercount. ⇒ NOT inside this diff (unmodified, pre-existing) and it does not ship.

⚠️ The pin must be run from the repo root — a guard in this repo rejects pnpm --filter ... exec vitest started from the package directory. My first attempt hit that guard and exited 1 without running a test; re-run from the root it is 30/30. Recording it rather than presenting the first exit as a failed measurement.

⚠️ Shared-box seconds throughout: the lock excludes other LOCKED runs only, not the check:* farm. One acquisition waited 5m58s; that time went to lock-free work.

PR-body readback delta — exact

REST PATCH (Content-Type: application/json; the first attempt returned HTTP 415 for omitting that header and changed nothing). Sent 19,772 bytes; a separate GET reads back 19,772 bytes, and diff -u of sent against stored is empty — byte-identical, zero delta. No footer was appended and no footer was downgraded: the stored body still carries exactly the two footers it already had (1 session-URL form, 1 bare, 2 rule lines), which are the residue of the earlier MCP-channel write. ⛔ Not repaired, not touched. The body contains zero lt/gt characters, so the sanitizer had nothing tag-shaped to eat; the only closing keyword near a card reference is the deliberate closing line on the PR body's first line — the keyword followed by this card's bare number, which is exactly what a PR body is meant to carry. ⛔ Spelled out rather than reproduced here, so this comment carries no keyword-plus-number pair of its own.

open_questions

1. Shape 1 vs shape 2 is now a live precedent, not just this block. I took shape 2 on a measurement (58/58, controls lit, and a real consumer already running it). But the standing pattern on this card is that prescriptive sentences in this docblock keep going wrong — the "reads it FROM here rather than restating it" line produced objectui#9359, and "fold before asking this set" produced this FAIL. A seat may reasonably hold that this docblock should describe and never instruct. If so, the fix is to delete the prescription and keep only the FOLD-CLOSURE relationship sentence — about two lines, no measurement lost. ⇒ Do you want a follow-up that makes this docblock descriptive-only as a rule?
2. The pin's five objectui#9358 citations are inside this diff. The order said report, not necessarily fix. Fixing them costs one commit on this same branch and removes a class the review has now flagged twice. ⇒ Fix on this head, or leave for the seat?
3. mergeable_state: behind — main has moved to efc1c9c400, past the merge-base dfb5850594. I did not merge or rebase (⛔ no history rewrite, and landing is the seat's). ⇒ Flagging only.
