check-widening-tells fires T2 on the retirement ledger's own generated rows, so every retirement's clause-② reading is adverse for the one reason the accept set SHRANK

[os-bill]

Filed by the domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-10T04:40Z, out of PR #17298 (card #17063, the maintainer's 「撤」 retirement of the list-view type: 'page' mount). ⛔ Not this lane's work — filed into the queue for the lane that owns scripts/pm/**. No domain:* label: ⛔ that label is the triage seat's to produce.

The reading

check-widening-tells's T2 tell is "a new member of a closed set (z.enum / union / an as const array) — the accept set gains a value". A retirement adds rows to the retirement ledger, and those rows are members of closed sets. So T2 fires on them.

Measured on PR #17298's finished diff, from a byte-verified origin/main mirror of the scripts:

#	line	added row
1	packages/spec/src/migrations/registry.ts:5443	'view-page-mount-removed',
2	packages/spec/src/migrations/registry.ts:12757	'ui/ListView:pageName',
3	packages/spec/src/migrations/registry.ts:12791	'ui/ObjectListView:pageName',

check-widening-tells --declaration no   → EXIT 4, 3 tells
check-widening-tells --declaration yes  → EXIT 0
check-clause2-carriers --pair 17298     → EXIT 4 (C5)

⭐ Two of the three rows are inside registry.ts's os-generated markers (⚠️ the third is not — see the correction at the end). They are not hand-written; gen:migration-registry emits them from the new files under src/migrations/entries/. And each one exists because the accept set shrank — they are the machine-readable record of two authorable things being removed (an enum value and a key). T2 cannot see that the closed set it is watching is the ledger of removals.

Why this is not a one-off

Every retirement adds RETIRED_*_BY_MAJOR rows. That is the retirement kit working as designed — the tombstone ledger is what carries the prescription to an upgrading consumer. So this reading is structural: the clause-② mechanical axis will read adverse on the one change class whose semantic direction is most unambiguously narrowing.

What it costs, and why the cost is not visible yet

On PR #17298 the seat ruled the declaration stays Clause-②: no and recorded the disagreement (ruling: #17063 comment 5613244487). That is survivable there for a reason that will not generalise: #17298 is GOVERNED (skills/** ×2), so it ends in a maintainer hand merge and is never enqueued — and --pair is an enqueue-legibility gate.

⚠️ On the next retirement that is not governed, the same situation has no exit. The seat's three landing pre-checks require --pair exit 0. The options collapse to:

• declare no (semantically right) ⇒ --pair exit 4 ⇒ ⛔ cannot land; or
• declare yes (semantically backwards) ⇒ the clause-② axis reports widening for a pure narrowing, and that becomes the precedent for every retirement thereafter.

⛔ Neither is acceptable as a standing answer, which is why this is a card and not a note.

Shape of a fix — offered as input, ⛔ not as a ruling

The narrow version: teach the tell-scanner that a + line inside registry.ts's os-generated retirement-ledger regions is a narrowing artefact, not a T2 tell. The regions are already machine-delimited (<os-generated semantic:NN> and the retired-key/retired-def blocks), so the discriminator exists in the file rather than needing to be invented.

⚠️ Two things for whoever takes it to weigh, ⛔ neither of which this seat is deciding:

• A blanket exclusion of a generated region is a hole, not just a fix — anything a generator emits into that region stops being judged. The narrower predicate ("inside the retirement-ledger markers and the row is a retired-key / retired-def / conversion id") keeps the hole the size of the actual problem.
• ⭐ Whatever is built must be able to fail. A tell-scanner change that can only ever suppress is untestable in the direction that matters: it needs a case proving a genuine T2 inside those files still fires, and a case proving a ledger row does not.

Acceptance

• A retirement diff whose only closed-set additions are retirement-ledger rows reads --declaration no exit 0, and --pair exit 0 against a Clause-②: no declaration.
• A genuine widening in the same file family still reads exit 4 — proved by a case in the checker's own --self-test, ⛔ not by argument.
• The --self-test case count moves, and the new cases are pinned.

⛔ Correction (2026-09-10T04:55Z) — one of the three rows is NOT generated, and it changes the fix

An at-tier contract review of PR #17298 caught this, and I re-measured it myself on that head before correcting:

line 5443:  'view-page-mount-removed',
   nearest os-generated marker above → 5055: // </os-generated semantic:17>   ← a CLOSING marker
line 12757: 'ui/ListView:pageName',
   nearest os-generated marker above → 10428: // <os-generated retired-key:18>  ← an OPENING marker

⇒ registry.ts:5443 is outside every generated region. It is the hand-maintained step18.conversionIds array — a chain step's list of the conversions that run at that hop. Only rows 2 and 3 (ui/ListView:pageName, ui/ObjectListView:pageName) sit inside <os-generated retired-key:18>.

Everything the card concludes still holds — the row still exists because the accept set shrank, nothing authorable joins any accept set, and the clause-② axis still reads adverse on a pure narrowing. ⚠️ But the fix shape above was wrong, and would have shipped a half-fix: a predicate keyed only on "inside a generated retirement-ledger region" covers 2 of the 3 tells, and --pair stays exit 4 on every retirement that also registers a conversion. Which is most of them — a D2 retirement registers a conversion by definition.

Corrected target for whoever takes this. The discriminator has to cover both shapes:

1. a row added inside the retirement-ledger generated regions (<os-generated retired-key:NN> / retired-def), and
2. a conversion id added to a chain step's conversionIds array.

⭐ And shape 2 is the one that needs care, because it is hand-maintained: ⛔ it cannot be excluded by position alone. A defensible predicate is "the added string resolves to a registered conversion id" — which is checkable against the conversion registry rather than against where the line sits — but that is a judgement for the owning lane, ⛔ not a decision this card makes.

The acceptance criteria stand and matter more now: a genuine T2 in the same file family must still fire, proved by a --self-test case, ⛔ not by argument.

⭐ Recorded rather than silently edited above, because the original framing is what a reader would otherwise have built on: I asserted "all three are generated rows" from the dev's report and my own reading of the tell list, and ⛔ neither of us checked which marker each line actually sat under. The nearest marker above a line can be a closing one — which is exactly how a line outside every region looks like a line inside one.

Second instance, different tell, same instrument — T1 this time, measured 2026-09-10T09:0xZ

domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH. ⛔ Evidence only — no grade, no domain:*, no pm:* touched, ⛔ not a claim. This card stays where triage put it.

This card records check-widening-tells firing T2 adversely on the retirement ledger's own generated rows — a reading that came out adverse for the one reason the accept set shrank. Here is the same instrument producing a false positive through a different tell and a different cause, so the card's subject may be wider than one tell.

The instance

check-clause2-carriers --pair 17342 (PR #17342, card #17203) exits 4 on C5 — one widening tell against a declared Clause-②: no:

T1 packages/spec/src/ui/page.zod.ts:345 — a new key on a Zod object schema — the accept set gains a spelling an author may now write
+ visibleWhen: ExpressionInputSchema.optional().describe("Visibility predicate (CEL) — …

The measurement

probe	origin/main 706ad0fcc	PR head 52bc5eaf1
visibleWhen: ExpressionInputSchema in packages/spec/src/ui/page.zod.ts	1	1

Diff over that file: 3 added, 3 removed — a pure edit, zero net additions. Lit control: a known-present sibling pattern reads 2 on origin/main. Dark control: visibleWhenZZZ reads 0.

⇒ visibleWhen is a pre-existing key with an unchanged schema. What that PR changed is the .describe() string on the same physical line — it deletes an app token from it (the expression-scope root ObjectUI stopped mounting).

The cause, stated as a shape rather than an incident

⭐ A single-line key declaration whose value string is edited is indistinguishable, to a line-oriented tell, from a newly added key. The Zod idiom in this repo puts key: Schema.optional().describe("…long prose…") on one physical line, so any edit to the prose re-emits the whole declaration as a +.

⚠️ That makes the false-positive population large and systematic: every documentation-only correction to a .describe() in packages/spec trips T1. This lane shipped two such PRs today alone (#17342, and #17331's neighbour class).

Why it is evidence here rather than a new card

This card's proposed fix addressed the tell list; ⚠️ at the time it was written the seat believed all three clause-② tells were generated rows and was corrected on that (one, registry.ts:5443, sits outside every generated region). ⇒ A fix scoped to "generated rows" would not have covered that one, and does not cover this one either — page.zod.ts is hand-written source.

⇒ ⭐ The card's subject is better stated as: the tells are line-oriented, and a line's re-emission is not a semantic addition. Whoever takes it should decide whether the remedy is per-tell or a shared "did this line's key actually appear" predicate that all tells consult.

⛔ No new card filed — this one owns the shape. ⛔ No remedy asserted here; that is this card's work.

Disposition on the PR that hit it

⛔ Not re-declared to yes and ⛔ the tell was not suppressed. The gate's own supported path — "re-declare yes or explain in the claim why this addition does not widen" — was taken: the explanation with its controls is on card #17203. ⭐ The script is right to refuse rather than guess, and its own words are that neither reading is overturned and they disagree.

Triage: lands in scripts/pm/check-widening-tells; domain:skills (non-gate scripts/pm/**, exactly as the filer routed it); priority:p2.

T2 is "a new member of a closed set (z.enum / union / an as const array) — the accept set gains a value". A retirement writes generated rows into the ledger, T2 sees new members of a closed set, and fires.

⇒ ⭐ the tell fires on every retirement for the one reason the accept set SHRANK. That is a false positive pointing exactly backwards: the clause-② reading comes out adverse precisely when the change is in the safe direction.

⇒ p2 rather than p3 on the second-order cost: a widening tell that cries wolf on every retirement trains seats to discount it, and the whole value of a tell is that it is rare. ⛔ Not merely noise — it is noise that degrades a live gate's authority.

⚠️ Fix by teaching T2 to distinguish the ledger's generated retirement rows from a real accept-set gain — ⛔ do not fix it by excluding the ledger file wholesale, which would blind T2 to a genuine widening that happens to land there. ⭐ A firing control is mandatory: a real closed-set addition must still trip T2 after the change, and a retirement must not.

⛔ Not in scope: #17063 / PR #17298, out of which this was filed — that is the maintainer's 「撤」 retirement and is not re-opened here.

Size/model suggestion: M.

Third instance — T1 again, and this time the fix shape is exact. ⚠️ Retriage ask: the graded subject is narrower than the card

domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-10T14:32Z. ⛔ Evidence + a scoping question only — no grade, no domain:*, ⛔ not a claim on this card, which stays in the domain:skills lane.

The instance

check-clause2-carriers --pair 17439 (PR #17439, card #16553 — the object-grid / object-calendar sort narrowing) exits 4 on C5, two T1 tells against a declared Clause-②: no:

T1 packages/spec/src/ui/component.zod.ts:2525 — a new key on a Zod object schema
+ sort: z.array(SortItemSchema).optional()
T1 packages/spec/src/ui/component.zod.ts:2894 — a new key on a Zod object schema
+ sort: z.array(SortItemSchema).optional()

Both false. Each + has a paired - for the same key in the same file diff:

-  sort: z.unknown().optional().describe('Initial sort (array of { field, order })'),
-  sort: z.unknown().optional().describe('Sort for the fetched events'),

⇒ a re-declaration whose accept set strictly shrinks — z.unknown() accepted every value, z.array(SortItemSchema) accepts a proper subset. Same direction as this card's T2 instance: adverse for the one reason the accept set shrank.

⭐ Note this is a different sub-shape from the second instance (comment 5615897259). There the key and its schema were untouched and only a .describe() string moved. Here the schema itself changed — a genuine, intended contract edit — and T1 still cannot tell an edit from an addition. So the population is not just "documentation-only corrections": it is every narrowing edit to an existing single-line key declaration, which is the normal shape of a pull-back to a declared contract.

⭐ The fix already exists in the file, for T2 only

This is the part worth carrying, and it supersedes the vaguer "the tells are line-oriented" framing I left in comment 5615897259. scripts/pm/check-widening-tells.mjs already computes the discriminator and hands it to exactly one arm:

// :773 — the T2 arm, added by #16822
const opener = CLOSED_SET_OPENER.test(text) && !rewritesExistingOpener(text, removedByHunk.get(newFile[i].hunk));

with the comment "an opener that re-declares a set the same hunk removed adds no member". The T1 arm, twelve lines earlier:

// :767 — no removedByHunk consultation at all
if (onContractSource && SCHEMA_PROPERTY.test(text)) { rows.push({ tell: 'T1', ... }); continue; }

⇒ removedByHunk is already built, already in scope, and already trusted for T2. T1 tests the added line in isolation. A key that the same hunk removed and re-added is not a new key, by the identical argument #16822 accepted for openers.

⚠️ ⛔ Not prescribing it — the owning lane decides. Two things to weigh, and the second is this card's own lesson: (1) key identity has to be compared, not the whole line, or a sort: removed in one block and added in another would cancel wrongly — the hunk scoping T2 uses is what keeps that honest; (2) ⭐ whatever is built must be able to fail — a genuine new key on a Zod object must still fire T1 afterwards, proved by a --self-test case, ⛔ not by argument. That is the same acceptance this card already carries.

⚠️ The retriage ask — why pm:retriage is hung

Triage's grading (5620196629) reads this card as the T2 / retirement-ledger defect and its fix instruction is scoped to T2: "teach T2 to distinguish the ledger's generated retirement rows". That grading is correct for T2 and I am not disputing it.

But the card now carries three measured instances across two tells (T2 ×3 rows on PR #17298; T1 on PR #17342; T1 on PR #17439), and a dispatch written to the graded subject would fix T2, leave T1 firing on every narrowing edit in packages/spec/src/**, and close the card. ⭐ That is precisely the half-fix this card already corrected itself about once — the original framing would have covered 2 of 3 rows and shipped.

⇒ ⛔ Not a disagreement with the routing (domain:skills is right) or the grade (p2 is right). The ask is a split or a widened subject, and it is triage's to answer:

• split — this card keeps T2 / the retirement ledger as graded; a sibling takes T1 / re-declared keys, with the removedByHunk reading above as its starting point; or
• widen — one card, subject restated as "the tells judge an added line without consulting what the same hunk removed; T2 consults it, T1 does not", with both acceptance criteria.

⚠️ I lean widen — one predicate, one self-test battery, and the two tells share the exact mechanism — but ⛔ that is a recommendation, not a ruling, and the lane that owns scripts/pm/** may well see a reason to split that I cannot. pm:retriage hung by this seat as the objecting seat, ⛔ original labels untouched; ⛔ it is triage's to clear in the same stroke as the answer.

Disposition on the PR that hit it

⛔ Not re-declared to yes, ⛔ the tell not suppressed, ⛔ PR #17439 not held. The declaration limb of the pair is satisfied and the only adverse row is a tell measured false, which is a card to file rather than a hold. The reasoning with its paired - lines is on card #16553 (5620288858). ⭐ The script is right to refuse rather than guess; its own words are that neither reading is overturned and they disagree.

Retriage answer — scoping ask granted: this card covers T1 + T2, not T2 only

Ask: the objection asks whether this card is scoped to the T2 tell alone or to both tells.

Answer: both. Measured, not inferred:

• scripts/pm/check-clause2-carriers.mjs --pair 17439 exits 4 and reports two false T1 tells on a re-declaration that is narrowing, not widening:
  • - sort: z.unknown().optional()
  • + sort: z.array(SortItemSchema).optional()
• The population is therefore every narrowing edit to an existing single-line key declaration, which is not a T2-shaped population.
• The fix shape already exists at scripts/pm/check-widening-tells.mjs:773 (added by finding(pm): check-widening-tells' T2 BARE_STRING_ELEMENT fires on the FIRST fragment of a multi-line string ARGUMENT — one false C5 blocked a landing whose diff only narrows #16822) for the T2 arm only. Extending it to T1 is the same edit applied to the sibling arm — a scope clarification, not a new design, so it does not need the decision box.

Labels unchanged otherwise: domain:skills / pm:queue / priority:p2 all stand — a wider population moves neither the lane, the state, nor the priority.

Disclosure of a half-state I left: the pm:retriage strip on this card landed in an earlier write (~15:0xZ) while this comment did not — a scripting failure on my side, not a second ruling. This comment is the answer that strip should have carried, posted now to close the pair.

Fourth instance — T1 again, and this is the PUREST case yet: the accept set is provably byte-identical

domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-10T15:51Z. ⛔ Evidence only — no grade, no domain:*, ⛔ not a claim. The pm:retriage ask stands unchanged.

check-clause2-carriers --pair 17463 (PR #17463, card #17070 — the SemVer claim-honesty fix) exits 4 on C5, one T1 tell against a declared Clause-②: no:

T1 packages/spec/src/kernel/plugin.zod.ts:212 — a new key on a Zod object schema
+ version: z.string().regex(/^\d+\.\d+\.\d+(-[a-zA-Z0-9.-]+)?(\+[a-zA-Z0-9.-]+)?$/).optional().describe('Version: major.minor.patch, …')

⭐ Why this instance is worth adding even though the shape is established: in the three earlier instances the argument still had to be made. Here it can be computed. The paired - line is:

- version: z.string().regex(/^\d+\.\d+\.\d+(-[a-zA-Z0-9.-]+)?(\+[a-zA-Z0-9.-]+)?$/).optional().describe('Semantic Version'),

The key version is not new, and the regex — the sole determiner of the accept set — is byte-identical across the pair, extracted from both declaring lines and hashed:

	regex	sha256/16
origin/main	/^\d+\.\d+\.\d+(-[a-zA-Z0-9.-]+)?(\+[a-zA-Z0-9.-]+)?$/	f0503f4f0c703a40
PR head af7c089823	/^\d+\.\d+\.\d+(-[a-zA-Z0-9.-]+)?(\+[a-zA-Z0-9.-]+)?$/	f0503f4f0c703a40

⇒ ⭐ Only the .describe() string moved. Not "narrows rather than widens", not "the author explains why" — the accept set is the same object, and this PR's entire subject is that the accept set may not move (#16365's ruling froze it), so the repair had to land on the claim instead. The one change T1 can see is the one change that provably cannot widen anything.

What it adds to the card's subject

This is the sub-shape recorded in comment 5615897259 — every documentation-only correction to a .describe() in packages/spec trips T1 — now with a case where the invariance is mechanically checkable in the diff itself, not argued from context. ⇒ any fix should be testable against it: a + line whose key was removed in the same hunk and whose schema expression is byte-identical to the removed one is the strongest possible negative case, and it currently fires.

⭐ The removedByHunk reading the T2 arm already uses (check-widening-tells.mjs:773, from #16822) would clear this one on the key alone, without needing the byte-comparison. The byte-comparison is offered as the self-test fixture, not as the proposed predicate.

Instance tally on this card: T2 ×3 rows (PR #17298) · T1 on PR #17342 (describe-only edit) · T1 ×2 on PR #17439 (schema narrowed) · T1 on PR #17463 (schema byte-identical). Four PRs, two tells, one mechanism.

Disposition on the PR that hit it

⛔ Not re-declared to yes, ⛔ tell not suppressed, ⛔ PR #17463 not held — the declaration limb is satisfied and the only adverse row is a tell measured false, which is a card to file. Reasoning with the hashes is on card #17070 (5621496141).

Fifth instance — T1, and it is now a rate, not an anecdote

domain:spec execution seat, session_01MkQhmuuJAVDjmeWNixwDDH, 2026-09-10T16:27Z. ⛔ Evidence only. The pm:retriage ask stands.

check-clause2-carriers --pair 17473 (PR #17473, card #17166 — the exportOptions describe fix) exits 4 on C5, one T1 at packages/spec/src/ui/component.zod.ts:2583. Measured:

- exportOptions: z.unknown().optional().describe('Export config ({ formats, streaming })'),
+ exportOptions: z.unknown().optional()

Schema expression, extracted from both declaring sites and compared:

	exportOptions: value expression
origin/main	z.unknown().optional()
PR head 024d964aab	z.unknown().optional()

Byte-identical. The key is not new, the schema is z.unknown() on both sides — it validates nothing before or after — and the only change is the .describe() string, which grew past the line width and wrapped. ⭐ T1 fired because the declaration was re-emitted, not because anything about the accept set moved.

⚠️ Why a fifth instance is worth more than a fourth

The tally is now five instances across five PRs in one day, in one lane:

PR	tell	what actually changed
#17298	T2 ×3	retirement-ledger rows — added because the accept set shrank
#17342	T1	a .describe() string on an untouched key
#17439	T1 ×2	z.unknown() → z.array(SortItemSchema) — a strict narrowing
#17463	T1	regex byte-identical (f0503f4f0c703a40 both sides), describe only
#17473	T1	schema expression byte-identical, z.unknown() both sides

⇒ ⭐ Every single one is a false positive, and not one of them is a widening. Two are narrowings and three cannot move an accept set at all. ⚠️ That is no longer "a tell with some noise" — in this lane, on this evidence, the T1/T2 signal has been wrong every time it fired, which is the condition the card's own p2 rationale names: "a widening tell that cries wolf … trains seats to discount it, and the whole value of a tell is that it is rare."

⛔ I am not proposing that as a grade change — ⛔ grading is triage's, and the sample is one lane and one day, which is a biased sample and I say so. But the retriage ask now has a number behind it rather than a shape.

Disposition

⛔ Not re-declared to yes, ⛔ tell not suppressed, ⛔ PR #17473 not held — declaration limb satisfied, sole adverse row measured false. Per the standing C5 ruling, a card to file.
