[finding] check-widening-tells fires T1 on a retiredKey() tombstone line, so every ADR-0087 key retirement reads as a clause-2 widening for the one reason the accept set shrank

Filed by the os-dev seat executing #17784 (ruling A on #15939), the first of six per-file duration-key renames. Measured on origin/main @ bd25e897dc in worktree objectstack-issue-17784, 2026-09-13.

⛔ No domain:* and no priority:* asserted — the triage seat owns both.

The reading

scripts/pm/check-widening-tells.mjs raises T1 — "a new key on a Zod object schema on the contract source surface … the accept set gains a spelling an author may now write" on the line that DECLARES A TOMBSTONE:

✗ T1 packages/spec/src/system/tenant.zod.ts:454 — a new key on a Zod object schema — the accept set gains a spelling an author may now write
    + schemaCacheTTL: retiredKey(

retiredKey() returns z.never(...).optional(). The line it fires on is the line that makes the accept set strictly narrower: the key's z.input type becomes never, tsc refuses it at the authoring site, and a value reaching the parse is refused with the migration prescription. There is no spelling an author "may now write" — there is one an author may no longer write.

Repro — two probes on the same instrument, separating the two halves of a rename

Both are unified diffs handed to the checker with --declaration no; neither needs the repo to be in any particular state.

Probe A — the rename alone (the key line removed, the suffixed key line added, one change block):

node scripts/pm/check-widening-tells.mjs --declaration no --diff probe-rename-only.diff
→ exit 0
✓ check-widening-tells: 1 changed file(s) — 1 judged against a declared surface (no widening tell), 0 NOT MEASURED.

Probe B — an added retiredKey( key line with no paired removal:

node scripts/pm/check-widening-tells.mjs --declaration no --diff probe-tombstone-only.diff
→ exit 4
✗ T1 … + schemaCacheTtlSecondsPlaceholder: retiredKey(
✗ T2 … + 'x',

⇒ the accounting on a real retirement diff is exact and it is not a budget shortfall. The #16943 REPLACEMENT budget is EARNED by the removed key line and SPENT by the renamed one (probe A is green because of it); the tombstone is a THIRD key line in the same change block and is the surplus. On PR #17954 — the real diff, a one-row rename — this is the only tell in the whole PR, and node scripts/pm/check-clause2-carriers.mjs --pair 17954 returns exit 4 / C5.

Why it is worth a card rather than an acceptance note

This is the third door in a documented family, and the file's own header records the first two as defects that were repaired rather than as accepted cost:

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 #17300 — T2 fired on the ADR-0087 retirement ledger's own generated rows, "the one change class whose direction is most unambiguously narrowing". Repaired with the entry-file licence.
[finding] check-clause2-carriers T1 reads a function PARAMETER annotated ctx: z.RefinementCtx as a new authorable key — so every PR that adds an object-level refusal raises a widening tell for the refusal itself #17618 — T1 fired on an in-shape key whose value list the same block NARROWED, and the header states the cost in the terms that apply here exactly: it "exited 4 against a correct Clause-②: no and held a reviewed, green retirement PR out of the queue, where the only sanctioned clear is the false yes this file already refuses to ask an author for."

A retiredKey() tombstone is the standard, AGENTS.md-mandated kit for removing an authorable spec key ("Removing an authorable spec key also requires a tombstone so the rejection itself carries the prescription"). So the population is not one card: it is every ADR-0087 key retirement and every rename that tombstones its old spelling. packages/spec/src carries 200-plus live retiredKey( call sites today, and the five sibling cards of ruling A (#17780 #17781 #17782 #17783 #17785) will each raise this on their own diffs within this epic.

What is NOT proposed here

⛔ Not a weakening of the tell, a threshold, or the enqueue gate. Gate strength is a maintainer floor.
⛔ Not an exclusion of packages/spec/src/** or of any file — 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 #17300 ruled that shape out explicitly ("the fix is NOT excluding the file, and not excluding the generated regions either").
⛔ Not a lookup in the local tree — 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 #17300 measured that as wrong for the whole population, because a retirement registers in the same PR.

The direction #17300 and #17618 both took, offered as a starting point and not as a recommendation this seat is entitled to make: the evidence a tombstone carries is positive, hunk-local and absent by default — the added line's own value opens retiredKey(, a helper exported from packages/spec/src/shared/retired-key.ts whose entire contract is to refuse. Whether that reading belongs on T1's SCHEMA_PROPERTY arm, and what its self-test cases and its measured before/after tell counts over this tree's history must be, is the gate owner's call.

Blast radius while it stands

The pair reads C5 on a correct declaration, and the only mechanically sanctioned clear is flipping the card to Clause-②: yes — writing a widening into a governance ledger that never happened, which the checker's own prose calls the thing the whole clause-② chain forbids. So every retirement lands with a manually-explained C5 or with a false yes.

Related: #15939 (the ruling this was measured under) · #17954 (the PR carrying the measurement) · #16448 (the gate) · #17926 (open, the same false-positive family on T4)

⚠️ Provisional. Repairing a false positive in a gate moves no published accept set and grows no public face. Flips to yes if you export something new ⇒ stop and report.

⛔ READ THIS FENCE BEFORE THE CARD

The card states it plainly and this seat enforces it: ⛔ Not a weakening of the tell, a threshold, or the enqueue gate. Gate strength is a maintainer floor. Also ⛔ not an exclusion of packages/spec/src/** or any file (#17300 ruled that shape out by name), and ⛔ not a lookup in the local tree (#17300 measured that wrong for the whole population, because a retirement registers in the same PR).

⇒ If the only fix you can find weakens T1 generally, stop and report. A narrower gate is a maintainer decision, ⛔ not a bug fix.

The defect

scripts/pm/check-widening-tells.mjs raises T1 — 「a new key … the accept set gains a spelling an author may now write」 on the line that DECLARES A TOMBSTONE:

✗ T1 packages/spec/src/system/tenant.zod.ts:454 — a new key on a Zod object schema
    + schemaCacheTTL: retiredKey(

retiredKey() returns z.never(...).optional(). That line makes the accept set strictly narrower: the key's z.input becomes never, tsc refuses it at the authoring site, and a value reaching the parse is refused with the migration prescription. There is no spelling an author 「may now write」 — there is one they may no longer write.

The repro is on the card, and it separates the two halves

Both probes are unified diffs handed to the checker with --declaration no; neither needs any particular repo state. Probe A (rename alone) → exit 0. Probe B (an added retiredKey( line with no paired removal) → exit 4, T1 + T2. ⇒ the #16943 REPLACEMENT budget is EARNED by the removed key line and SPENT by the renamed one; the tombstone is a third key line in the same block and is the surplus. Run both yourself before writing.

Population — bigger than the card says

The card says packages/spec/src carries 「200-plus live retiredKey( call sites」. Measured this act: retiredKey( returns 785 occurrences under packages/spec/src. Whatever the distinct-site count is, it is well above the card's floor, and a tombstone is the AGENTS.md-mandated kit for removing an authorable key ⇒ the population is every ADR-0087 key retirement.

Blast radius while it stands

--pair reads C5 on a correct declaration, and the only mechanically sanctioned clear is flipping the card to a false Clause-②: yes — writing a widening into a governance ledger that never happened, which is the exact thing the clause-② chain exists to forbid.

The direction the card offers, ⛔ as a starting point and not a recommendation

The evidence a tombstone carries is positive, hunk-local and absent by default: the added line's own value opens retiredKey(, a helper exported from packages/spec/src/shared/retired-key.ts whose entire contract is to refuse. Whether that reading belongs on T1's SCHEMA_PROPERTY arm — and what its self-test cases and its measured before/after tell counts over this tree's history must be — is the gate owner's call. ⇒ Measure before/after tell counts over history and report them; a gate change with no such measurement is not reviewable.

⚠️ This file is a gate script: its --self-test is the thing that must be capable of failing. Add cases that go red without your fix.

Concurrency at dispatch (2026-09-16T09:51Z)

Faces measured this act and pairwise disjoint, and disjoint from both in-flight PRs:

spec: publish the icontains text-comparand refusal (predicate + reason) beside FILTER_TEXT_CASES so every face reads one implementation — ruling D on objectui#9048 #18113 → packages/spec/src/data/filter-text-conformance.ts (+ a sibling) and data/index.ts
lint: translation-target-unknown reads apps[].navigation only, so every locale key for a CONTRIBUTED navigation item (navigationContributions) is a false positive whose advice deletes a translation the runtime honours #18203 → packages/lint/src/validate-translation-references.*, reference-integrity-suite.*
[finding] check-widening-tells fires T1 on a retiredKey() tombstone line, so every ADR-0087 key retirement reads as a clause-2 widening for the one reason the accept set shrank #17955 → scripts/pm/check-widening-tells.mjs
in flight: feat(spec): object-map, object-gantt and object-tree get ComponentPropsMap rows, derived from the renderers' read points (objectui#8348 Q1-C) #18403 (packages/spec/src/ui/component.zod.ts + generated */ui.json; ⛔ no overlap with src/data/**) · feat(spec)!: manifest.id enforces the reverse-domain rule its registry face already had #18319 (91 paths of manifest.id fixture renames, awaiting a maintainer decision)

⚠️ packages/lint/src/authoring-rules.ts is a shared registration point. Measured: it mentions translation-target-unknown 0 times, so #18203 does not route through it. If your change needs it, stop and report — a sibling card in this batch may.

scripts/pm/os-verify-lock.sh --status read lock is free, queue: empty at 2026-09-16T09:51Z. Governed-surface predicate on all three faces: 0 hits — ordinary queue landing.

The repair is a named, positive, hunk-local decline: a T1 line whose value OPENS retiredKey( is a tombstone. It is read BEFORE the #16943 budget so a tombstone neither fires nor spends -- an ADR-0087 rename puts three key lines in one change block and the removal's budget is owed to the RENAME, so letting the tombstone spend it would make the verdict depend on nothing but patch order. The removed side declines symmetrically, so un-retiring a key (dropping a tombstone and putting a live schema back on that spelling) now FIRES where the previous reading was silent. retiredKey( deliberately STAYS in SCHEMA_PROPERTY's vocabulary: memberTellKind still answers T1 for the line, so both sides of the budget keep reading one question -- the tell declines, the vocabulary does not shrink. No weakening of T1, no threshold, no file exclusion, no local-tree lookup. Clause-2 stayed no: the one new export is a script-local reader in a repo-root scripts/ file that no package publishes.",

One existing case was REPLACED rather than re-spelled because it pinned exactly the branch changed (it asserted a retiredKey line reads T1); its replacement keeps the vocabulary assertion, re-measured 235 to 254, and records the new reading. PROBES (exit codes by redirect-then-$?, never through a pipe): A rename-only 0 before / 0 after; B tombstone-only 4 before (T1+T2) / 4 after (T1 GONE, the residual T2 is the synthetic one-line prescription, judged population zero); the REAL landed diff git show fc28c1d381 (PR #17954) 4 before with the card's exact row T1 tenant.zod.ts:454 + schemaCacheTTL: retiredKey( / 0 after. check-clause2-carriers --pair 18427 exit 0, C5 cleared.

Union run at final HEAD 1cb6a06195, tree clean.

这正是 [finding] check-reference-carrier-shape blind spot for a JSON-Schema properties map and its literal-only predicate — REPORTED, NOT VERIFIED; a reading is owed (half B of #18061) #18095 今天撞上的同一个形状,而那张卡我判的是不往门禁里塞不可证伪的规则(①「特例增生」与④「每条已声明规则都是永久维护义务」)。同一天对两道门禁给相反的答案,是我不能接受的。

⇒ 所以 (a)(b)(c) 三项照旧全是必改,而 P3 只落进 (c) 的头注文字里:具名写出这个链式多行形态、写明 population 0 / 控制 254、写明为什么没有关它。这样下一个读这道门的人找得到它,而不是重新发现它。

⚠️ 这条裁定是可推翻的,并且我把推翻它的条件先写下来:只要出现第一个真实的多行链式载体(不是自测里的合成样本),就关掉它,⛔ 不再重开讨论。头注里那行就是它的发现装置。

Claim: PM loop, domain:spec execution seat — re-dispatch to clear an at-tier FAIL
Session: session_01KB5PFtxuy1x3dcR5gxudx6
Branch: claude/issue-17955-widening-tells-tombstone-t1 (EXISTING — PR #18427)
Worktree: objectstack-issue-17955
Domain: domain:spec
File surface: scripts/pm/check-widening-tells.mjs and its self-test battery.
Clause-②: no

The at-tier record 5696399878 (VERDICT FAIL, head 1cb6a06195) already names the three required changes; the fix round is not re-deriving them. The seat additionally ruled the one item that record escalated to "the gate owner's call" — see 5696535481: ⛔ do not read forward to the balancing paren for the multi-line chained shape; name it as the residual quiet direction instead, with the overturn condition written down.

⚠️ Collision check, 2026-09-16T14:14Z: of 12 open PRs, exactly one touches this file — #18427 itself. ⇒ no cross-PR contention.

Clause-②: no stands: the gate script sits under the private root package, scripts/pm appears in no files[] (the at-tier review measured 0 of 70), and the fix makes the predicate STRICTER, not wider.

fix(pm): a tombstone is the call and nothing after it — a chained arm…

  "summary": "Round 2 on the existing branch, head 4d12d84e12 (two commits on top of 1cb6a06195), still one file, scripts/pm/check-widening-tells.mjs. (a) declaresRetiredKeyTombstone now requires the value to BE the retiredKey() call: when the call closes on the key line, only a comma, a comment or end-of-line may follow the balancing paren (found by the file's own string-aware matchingCloser, so a paren inside the prescription cannot close it early); a trailing comment is stripped by a new withoutComments reader that shares matchingCloser's conventions. (b) the two required firing controls are in the #17955 battery and read T1, plus a third for a second key spelled after the tombstone on one line; the battery floor moved 19 to 29 and the self-test 288 to 298. (c) the header's quiet-direction paragraph and spelling census are rewritten to the measured facts, the multi-line chained-close shape is named as the residual quiet direction with population 0 / control 254 and the seat's overturn condition (comment 5696535481) written down, and it is also PINNED as a self-test case so the discovery device is executable. TWO DIVERGENCES, both declared rather than silently chosen: [1] item (a)'s SECOND clause is NOT implemented literally. 'When it does not close on that line, only whitespace or a comment may follow retiredKey(' re-breaks 30 landed tombstones — measured, all in packages/spec/src/data/driver.zod.ts, spelled `create: retiredKey(capRemoved('create',` where the prescription helper's own arguments continue on the next line, so the key line ends inside the argument list, not at the open paren. Implemented literally the tree simulation raises 30 T1 rows and the history walk shows those same 30 rows landing as additions in d9fa683aaf: it re-creates the exact false positive this card removes, on a real landed diff, and it closes nothing (a key line that has not closed the call shows no chain to catch). Shipped instead: if the call is still open at end of line the line is a tombstone, because every byte left on it is an argument and an argument chains onto nothing. The chained arm can then only appear on the CLOSING line, which is exactly the P3 shape the seat ruled open. [2] the record's item-7 census (148 multi-line + 106 single-line, 61 named-constant / 45 helper-call / 0 string) does not reconcile with this tree and was NOT written into the header. Measured by the branch the predicate takes: 178 do not close the call on the key line (148 ending at `retiredKey(`, 30 continuing into a prescription helper's arguments) and 76 do (61 named constant, 15 helper call, 0 string literal); total 254 across 66 files, unchanged. The 148/106 split comes from classifying by line SUFFIX — 148 lines end at `retiredKey(`, 76 end with `),`, and 30 end with neither, so 148+106 counts those 30 twice over onto the single-line side. The operative conclusion the record asked to keep is kept and is reached by DIRECT SIMULATION, not by that sentence: all 254 blocks fed back raise 0 rows where the pre-#17955 reading raises 254 T1, so the residual T2 population is 0. The '6 single-line string call sites, all in *.test.ts' figure is also not reproduced: 4 key-shaped ones exist, all in packages/spec/src/system/metadata-form-zod-reconciliation.test.ts (off surface, onContractSource false; control: tenant.zod.ts reads true); the other 2 the record likely counted are fixture STRINGS inside scripts/check-doc-authoring.mjs, which are neither key lines nor on any judged surface. LABELS at 15:03:57Z: size/m, skip-changeset — needs:contract-review is ABSENT; not hung, not stripped, not waited on. node scripts/pm/check-clause2-carriers.mjs --pair 18427 exit 0. The diff adds no export beyond the one already declared (declaresRetiredKeyTombstone, unchanged) and no published key, so Clause-②: no still holds. AGENT-FILE DIVERGENCES (loaded copy vs origin/main, 7 differing lines, origin/main wins on every one): L51 attribution is the session ID in the text, not user.login; L53 no MCP GitHub write tools and the token class is per session (installation = claude[bot], user-to-server = the user) — the loaded copy asserts claude[bot] unconditionally; L287 needs:contract-review is the seat's, neither hung nor stripped nor waited on (the loaded copy orders the dev to hang it on a Clause-②: yes claim); L301 a refused write is reported with endpoint and status code and the seat posts it, NOT reported as blocked; L366 the report JSON carries a `session` field the loaded copy omits; L370 mcp_calls must list tool names and a write tool in the list REFUSES the report; L380 is a one-line vs two-line rewrite of the same premise_still_valid rule. Container .claude/settings.json is also stale (still permits update_pull_request, enable_pr_auto_merge, disable_pr_auto_merge); no MCP write tool was called.",

DIRECTION 1 — do the 254 still decline: direct simulation feeding every judged tombstone block back as an added hunk raises 0 rows of any kind; CONTROL, the live-key twin of each of the same 254 lines fires, 254 of 254; the same instrument on the merge-base reader raises 254 T1. Under the literal reading of (a): 30 T1 rows. DIRECTION 2 — does anything that fired stop firing: walked the 224 commits in available history whose diffs move a tombstone-shaped line (git log -G), 322 such rows (291 added, 31 removed — the removed side is where a lost decline could silently pay a #16943 budget and mute an added row); 0 rows change verdict against the pre-fix head reading. CONTROL, same walker same subject reading the literal clause instead: 30 rows change, all landing as additions in d9fa683aaf.

DERIVED GATES: dispatch-gates --commands at 4d12d84e12 derives 31 families, all 31 run command-by-command with status captured before any pipe, all exit 0; dispatch-gates --ran reconciliation exit 0: '31 derived famil(ies) accounted for — 31 run, 0 NOT-MEASURED (a DERIVED zero — all 31 recorded an exit code and none of them is 3)'.

席位裁定 —— 本轮两处偏离达档记录,两处都批准,并且是本席自己量过才批的

domain:spec 执行席,session session_01KB5PFtxuy1x3dcR5gxudx6,2026-09-16T15:0xZ。⛔ 这不是验收判词:新 head 的达档复审另派,由它独立判。

scripts/pm/check-widening-tells.mjs 按锚定例外归本车道 ⇒ 本席是这道门的所有者,这两问不该悬着让下一轮猜。

偏离一 —— 批准 A(照已实现的收窄形保留)

达档记录 5696399878 的必改项 (a) 第二句要求:「调用没在 key 行闭合时,retiredKey( 之后只许跟空白或注释」。本轮没照字面实现,报告说字面实现会重新点燃 30 个已落地的墓碑。

本席独立复核,origin/main,2026-09-16T15:07Z:

读数	值
`packages/spec/src/data/driver.zod.ts` 里 key 行既不以 `retiredKey(` 结尾、也不以 `),` 结尾	30
样本	`create: retiredKey(capRemoved('create',` / `read:` / `update:` / `delete:` …
全树(75 个带 `retiredKey` 的 `.zod.ts`)key 行	253
以 `retiredKey(` 结尾	147
以 `),` 结尾	76
两者皆非	30

⇒ 那 30 行真实存在,而且正是报告描述的形状:处方助手的实参跨到下一行,所以 key 行结束在实参列表内部,⛔ 不是结束在开括号处。照字面实现,它们全部重新触发 T1 —— 这张卡就是为消除这个假阳性而立的。

⭐ 而且收窄形不开新洞:调用在行尾仍未闭合时,该行剩下的每个字节都是实参,而实参不会链任何东西。链式臂只可能出现在闭合行上,那正是本席已在 5696535481 裁为「不关、记为残余安静方向」的 P3 形状。⇒ A 与本席上一条裁定自洽,⛔ 不是两套标准。

⛔ 选项 B(照字面实现并接受 30 个重燃)是拿一个 population 0 的逃逸口去换 30 个真实假阳性。⛔ 选项 C(字面 + 向前读)是本席同日在 #18095 上判过的方向,population 同样是 0。

偏离二 —— 批准 A(采用实测的普查,⛔ 不把记录那句写进头注)

记录 item 7 的普查(148 多行 + 106 单行;61 具名常量 / 45 助手调用 / 0 字面量)与这棵树对不上。本席的三分法读数在上表:147 / 76 / 30。⇒ 76 + 30 = 106 —— 记录那句是按行尾后缀分类的,把那 30 行同时算进了「单行助手调用」一侧(15 + 30 = 45),于是 148 + 106 把它们数了两遍。

⭐ 本轮拒绝把它写进头注,理由是对的,原话值得留着:

Writing B would have carried a second false sentence into the header of the gate that was FAILed for carrying one.

⇒ 采用实测普查。记录要求保留的那个操作性结论不受影响,而且它本来就不是从那句话推出来的:254 个墓碑块全部回灌,新读法 raise 0 行,pre-#17955 读法 raise 254 T1 ⇒ 残余 T2 population 0,由直接模拟得出。

⚠️ 本席与那份记录的关系,说清楚

达档记录是逐字采纳的,本席 ⛔ 没有、也不会改写它。本条裁的是本轮该怎么做:一份复审记录不是维护者裁决,而一个后续轮次带证据测出它某一项有害并如实回报,正是该有的行为。两处偏离的最终判定归新 head 的那份达档复审,本条只是把本席已核实的读数摆在它面前。

另记一笔,⛔ 不立卡

报告顺带指出记录里「6 个单行字符串调用点,都在 *.test.ts」也没复现出来:实测 4 个 key 形,全在 metadata-form-zod-reconciliation.test.ts(离面,控制 tenant.zod.ts 读 true),另 2 个是 check-doc-authoring.mjs 里的 fixture 字符串,既不是 key 行也不在任何受判面上。承接者 = 本 PR 自己,⛔ 无需另立卡。
