[rebuild of #19421] [finding] zod 4.4.3's treeifyError and error.format() throw on any issue path containing __proto__ — so the formatter crashes on exactly the refusal PR #19147 landed to make that key safe

Ruled: 5770530634 · letter B · 2026-09-22T02:51Z — 一类自裁 (summon #26); zod bump workspace-wide as its own PR + regression pin; state pm:queue

Ruled: 5778996187 · letter B · 2026-09-22T15:11Z — 一类自裁 (summon #27, director seat), authority 5774631464; #19730 closed completed, so the block is satisfied and round 4 executes the ruled shape on PR #19658.

✅ UNBLOCKED — the C9 blocker cleared when this seat took over the unreleased claim on the maintainer's word (takeover comment 5790816753, 2026-09-23T08:14Z); the card is pm:dispatched again.

(History — cleared by the takeover above.) ⛔ C9: check-clause2-carriers --pair 19658 exit 4 — domain:spec seat 4's claim 5769208551 (2026-09-21T23:49:59Z) was never released before this seat's 5771265719 (2026-09-22T04:35:38Z) took the card. Rounds 4 and 5 ran under it. ⛔ No further work until seat 4 posts its own Release:; the delivered work stands on the branch and the PR stays draft.

⭐ REBUILD of card #19421, whose original is unreachable. Filed by the domain:spec seat 4 (session_01AmH9bKvGoLjiY86Q4Z3og2, seat post #18917) on 2026-09-21, under the maintainer's instruction to rebuild the cards lost when the os-sam account was banned.

⛔ The original is not deleted and ⛔ nothing here overrules it. GET and PATCH on …/issues/19421 both answer 404; a card this seat filed answers 200 on the same path, so it is ⛔ not a token or rate problem.

⚠️ This card had fallen out of every listing, which is why it was nearly lost

The ban does not only break the single-issue read: the card disappears from GET /issues?labels=… as well. Measured at rebuild time — the domain:spec · pm:queue listing returned 93 cards at 2026-09-21T03:45Z and 80 now; of the 17 that left, eleven closed or moved legitimately and six are simply unreadable: #19354, #19368, #19377, #19389, #19410, #19421.

⇒ nothing would ever have surfaced this card again. Its body below is reproduced from a read this seat took at 2026-09-21T03:45Z, before the ban — ⛔ not reconstructed, ⛔ not summarised. Its original labels were priority:p2 · pm:queue · domain:spec, and this rebuild carries them; ⛔ a re-grade is triage's, not this seat's.

Rebuild ledger for the ban: #19384 → #19541 (closed not_planned under ruling #208) · #19474 → #19542 (live, PR #19517) · #19389 → #19568 · #19377 → ⛔ not rebuilt, already closed completed with its PR merged · and this batch: #19354, #19368, #19410, #19421.

The original card, reproduced verbatim below, ⛔ not rewritten

Path: P3 | 那条路第 3 步「验证响亮拒绝错的」 | zod 4.4.3 的 treeifyError / error.format() 在任何含 __proto__ 的 issue path 上抛错 ⇒ 崩在 PR #19147 为让该键安全而落的那条拒绝上
分诊重测与定级:2026-09-20T18:58Z
Filed by the domain:spec seat 3 execution seat (seat post #18883, session_01HnRAeVTLJevtQ5iCPX6JSm), from the out_of_scope_findings of the #19151 round. ⛔ Filed unassigned, ⛔ no priority:*, ⛔ no domain:*, ⛔ no type — routing and grading are triage's. ⛔ Not a claim. ⛔ Not a ruling.

The defect

zod 4.4.3's treeifyError and error.format() throw

TypeError: Cannot read properties of undefined (reading 'push')

on any issue whose path contains __proto__.

⭐ The bite is the coincidence: the refusal PR #19147 landed — to stop a __proto__ key being silently dropped — produces an issue at path ['assignments', '__proto__']. ⇒ a caller that formats that refusal crashes on it. The guard turned a silent drop into a loud refusal, and the loud refusal is one the standard formatter cannot render.

⏱️ Measurement — attributed, ⛔ NOT re-measured by this seat

Reproduced first-hand by the #19151 round against PR #19147's landed guard, with a lit control on the same schema: an ordinary refusal path formats fine; the __proto__ path throws.

⛔ This seat did not re-run it. What this seat did verify is the in-repo half that makes it reachable: the landed guard is on the assignments record (builtin-node-config.zod.ts), and #19151's PR keeps the same path shape deliberately.

⚠️ The vendor half is the part to re-take before acting: whoever takes this card re-reads zod 4.4.3's formatter itself, the way #19151's round re-read handleCatchall rather than trusting the quotation it inherited. This card's premise arrives second-hand and says so.

Why it is its own card and not part of #19151

#19151's PR deliberately keeps the landed sibling's path shape and adds no new exposure class. Changing the path for one of the two guards would create two dialects of the same refusal and pre-empt a decision belonging to whoever takes this question.

The one-line remedy the #19151 card already records is path: [] — ⚠️ recorded here as the option that was named, ⛔ not as this card's recommendation: emptying the path removes the crash and the information about which key was refused, which is a trade this seat has not measured and does not own.

What this card does NOT claim

⛔ No claim about other zod versions — 4.4.3 is what packages/spec resolves (one version, measured in the #19151 round). ⛔ No claim about which callers actually format these errors: the blast radius was not censused, and 「the formatter throws」 is only a live defect where something calls it on that path. ⛔ No claim that #19147 was wrong — it was right, and the crash sits in the vendor formatter, ⛔ not in the guard.

⚠️ Adjacent and not this card: health.circuitBreaker and the rest of the ADR-0049 connector worklist are unrelated; and the __proto__ family's remaining sites are governed by ruling A-narrow (5725370319 on #17852), which forbids a sweep.

⚠️ Reading-time: 2026-09-21T23:49Z.

Why `Clause-②: no`, judged from the card CONTENT

Clause ② asks whether this PR puts a new key on a published payload or widens the accept set. The remedy
this card contemplates does neither: the refusal stays a refusal, and the option the card names
(path: []) narrows what the error reports. ⛔ Judged from content, ⛔ not from the path hint — the
--tier tool says clause ② is not reachable from paths, and this seat read a hint as a verdict once today.

⚠️ The remedy is not settled, so the executing dev re-judges from its own diff and reports a mismatch
rather than working around it; the correction channel is a Clause-②-correction: on this card, which only
this seat can write.

⚠️ Consequence to expect, ⛔ not a defect: with Clause-②: no and a changeset grading only
@objectstack/spec at patch, Check Changeset goes red for as long as this seat's
needs:contract-review carrier hangs — judgeLevel's enforce verdict is 「the axis is CARRIED, moved
packages graded patch and NONE of them graded minor or above → exit 1」. That is the designed state, ⛔ no
commit clears it, and the strip at review PASS is what clears it.

Premise re-measured at head `1c16889a61`, ⛔ not adopted

leg	reading
the version `packages/spec` declares	`packages/spec/package.json:324` — `"zod": "^4.4.3"`
what is installed	4.4.3
⚠️ and a second one in the store	`zod@4.6.1` is also present under `node_modules/.pnpm/` — ⇒ the repo is not single-version, even though `packages/spec` resolves one. The card says 「one version, measured」; that is true of this package and ⛔ not of the tree
the landed guard	present, `packages/spec/src/automation/builtin-node-config.zod.ts`, 7 lines naming `__proto__`, citing `#19151` and `#18847`
`__proto__` sites under `packages/spec/src/**`	31 files — the census the card says was ⛔ not taken

⚠️ What this card does NOT authorise, carried forward verbatim

⛔ The card does not recommend path: []. It records it as 「the option that was named」 and says
emptying the path removes the crash and the information about which key was refused — 「a trade this
seat has not measured and does not own」.
⛔ No sweep. The __proto__ family's remaining sites are governed by ruling A-narrow
(5725370319 on finding(spec): zod z.record() SILENTLY DROPS a __proto__ key from its parse OUTPUT while reporting success — ObjectSchema accepts the document and hands back a different one #17852), which forbids one. The 31 files above are context, ⛔ not a worklist.
⛔ The premise is second-hand: reproduced by the [finding] the third __proto__ site: AssignmentConfigSchema's own .catchall() silently drops a TOP-LEVEL flow variable named __proto__ #19151 round, ⛔ not by this seat. The card's own
instruction is that whoever takes it re-reads zod 4.4.3's formatter itself.
⛔ The blast radius was not censused: 「the formatter throws」 is a live defect only where something
calls it on such a path.

  "summary": "The card's premise is TRUE and re-measured first-hand against zod 4.4.3's own source, but it is NARROWER than the defect. Mechanism, read from v4/core/errors.js: treeifyError builds each node with `(_a = curr.properties)[el] ?? (_a[el] = { errors: [] })` and formatError with `curr[el] = curr[el] || { _errors: [] }`. Both create-if-absent idioms READ THROUGH THE PROTOTYPE CHAIN, so for any path segment naming an inherited Object.prototype member the read returns a non-nullish value, the node is never created, and `curr` lands on the inherited object instead of a fresh node. The throwing line is `curr.errors.push(...)` (treeify) / `curr[el]._errors.push(...)` (format): `.errors` / `._errors` is undefined on Object.prototype. __proto__ is special ONLY in being an accessor (its write also hits the setter); constructor, toString, valueOf, hasOwnProperty, isPrototypeOf, propertyIsEnumerable and the rest collide identically. Lit control: `prototype` does NOT collide (plain objects do not inherit it) and formats fine. SECOND failure mode the card did not have: when the colliding segment is NON-TERMINAL nothing throws at all. The formatter silently returns a tree with the error message MISSING and writes a property onto a GLOBAL (measured: Object.prototype.properties, Object.prototype.source, Object.properties, Object.type). After one such call an ORDINARY, UNRELATED error formats to {\"errors\":[]} with its own message silently lost, for the rest of the process. That is silent tolerance plus prototype pollution inside the error formatter - the same class of harm the #19147 guard exists to stop, one layer up. BLAST RADIUS IN THIS TREE IS EMPTY: nothing in objectstack calls treeifyError, formatError, error.format(), flattenError or prettifyError. Both in-repo zod-error renderers (spec/src/shared/error-map.zod.ts and spec/src/api/zod-issues-to-fields.ts) are path.join('.')-based and collision-safe by construction. DECISIVE: zod 4.6.1 ALREADY FIXES ALL OF IT upstream, with hasOwnProperty + Object.defineProperty, and its own source comment names \"__proto__\" and \"constructor\" - the same diagnosis. 4.6.1 is already in this repo's pnpm store (better-auth pulls it) and every workspace range is ^4.4.3, which already admits it; latest on the registry resolves 4.6.5. NO PATCH WAS LANDED and the working tree is byte-clean at base 1c16889a61: every available remedy is OUTSIDE the declared file surface `packages/spec/src/automation/ . .changeset/` - `path: []` lives in packages/spec/src/shared/record-proto-key-guard.ts (the path is hardcoded in refuseProtoOwnKey), and the zod bump touches 12 package.json files plus pnpm-lock.yaml. Reported as a breach instead of worked around, per the claim parameters. Clause-2 re-judged from my own diff: the diff is EMPTY, so `no` holds trivially - no new key on a published payload, no widening. No mismatch to report.",
  "tests": "NO CODE CHANGE, so there is nothing to build, test or gate. `node scripts/pm/dispatch-gates.mjs --commands` (run in the worktree, stderr names objectstack-ai/objectstack at 1c16889a61) prints: 'this branch changes nothing against origin/main (merge base 1c16889a6) - nothing to derive'. `git status --porcelain` empty; `git diff HEAD` empty. What WAS run is measurement, all exit codes captured before any pipe. (1) VENDOR RE-READ, first-hand: node_modules/.pnpm/zod@4.4.3/node_modules/zod/v4/core/errors.js, treeifyError at line 76 and formatError at line 35; resolved from packages/spec via createRequire, which printed zod version 4.4.3 - so the version read is the version packages/spec resolves. (2) REPRODUCTION AGAINST THE LANDED GUARD with a lit control on the SAME schema, real safeParse through AssignmentConfigSchema, exit 0: LIT CONTROL, the array legacy form, issue path ['assignments'] - treeifyError OK and error.format() OK, both rendering the full prescription; SUBJECT 1, JSON.parse('{\"assignments\":{\"__proto__\":\"x\"}}'), issue path ['assignments','__proto__'] - BOTH THROW TypeError: Cannot read properties of undefined (reading 'push'); SUBJECT 2, top-level catchall guard, issue path ['__proto__'] - both THROW the same. Card premise reproduced exactly. (3) ISOLATED FAILURE-MODE MATRIX, globals scrubbed before and after every row so no row contaminates the next, exit 0. treeifyError / format on zod 4.4.3: ['assignments','renamed'] OK message=KEPT globals=none (dark control); ['assignments','__proto__'] THROW; ['assignments','__proto__','source'] OK message=LOST globals-written=[Object.prototype.properties] (treeify) and [Object.prototype.source] (format); ['assignments','constructor'] THROW; ['assignments','constructor','source'] OK message=LOST globals-written=[Object.properties] / [Object.source]; ['assignments','toString'] THROW; ['assignments','prototype'] OK message=KEPT globals=none (lit control proving the collision is Object.prototype membership, not reserved-looking spelling). (4) CROSS-CONTAMINATION, measured: after ONE polluting call, z.treeifyError on an ordinary unrelated error returns {\"errors\":[]} - 'does it still carry its own message? NO - SILENTLY LOST'. (5) CLASS REACHABILITY WITHOUT ANY GUARD, through ObjectSchema.fields (a z.record with author-named keys, outside automation/): a field named `constructor` with an invalid type gives path ['fields','constructor','type'] - OK but globals-written=[Object.properties] / [Object.type]; a field named `toString` gives path ['fields','toString'] - BOTH THROW. HONESTY NOTE: in this run (5) the dark-control row ('amount') also reported message=LOST, which is an artifact of my predicate (zod's invalid-value message does not echo the literal I grepped for), NOT a real loss - so row (5) is sound on the POLLUTION axis only; the message axis is carried by run (3), which used a controlled message and whose dark control read KEPT. (6) ZOD 4.6.1 CONTROL, same probes against node_modules/.pnpm/zod@4.6.1, exit 0: every path OK, including ['__proto__'] under flattenError, which 4.4.3 also throws on ('fieldErrors[sub.path[0]].push is not a function'). (7) IN-TREE CENSUS, instrument `git grep -nI` over 9170 tracked files at 1c16889a61: treeifyError 1 hit (a prose comment in spec/src/shared/error-map.test.ts), formatError 11 hits (all cel-js `formatErrorWithHighlight`, unrelated), flattenError exit 1 / 0 hits, prettifyError exit 1 / 0 hits, '.format()' exit 1 / 0 hits. Zeroes paired with their radius and with targets inside it: LIT zodIssuesToFields 102 hits, LIT ZodError 324 hits; DARK 'zzznotapattern' exit 1. (8) BUMP-COST PROBE, `pnpm update zod -r --lockfile-only`, exit 0: it moves 12 workspace manifests from ^4.4.3 to ^4.6.5 and rewrites pnpm-lock.yaml (190 insertions / 196 deletions), dragging unrelated drift along (postcss 8.5.26 to 8.5.28, a drizzle peer-set change) - i.e. a real dependency-upgrade PR with its own verification round, not a one-liner. FULLY REVERTED: `git checkout HEAD -- .`, then pnpm-lock.yaml verified byte-identical to its HEAD blob 06d41005bad2e118da2e1b4a8d83f284ff1ffd1c by git hash-object, plus packages/spec/package.json and packages/runtime/package.json likewise, and `git status --porcelain` empty.

B SHRINKS it: the defect dies at its source for all three formatters and all colliding names, and no special case is ever written. C is neutral. Derived from axis 1 alone: B. (2) ACTUAL BUSINESS PULL - 今天谁撞上;零拉动默认 defer 或 remove: in-tree, ZERO, censused. In the sibling repo objectui three renderers call error.format(), but on spec strictObject schemas whose paths carry only declared key names, so not reachable today. The real puller is a consumer of published @objectstack/spec formatting a refusal from a record-keyed slot - real, but not censusable from here. Note the guard is the one thing that RELIABLY manufactures a colliding TERMINAL path, so #19147 did raise the odds. The zero-pull default argues for deferring A specifically; it does not argue against B, which is routine dependency hygiene with independent value. (3) AI-ERROR PREVENTION - 闭合枚举优于自由结构,响亮拒绝优于静默容忍: this axis is decisive and it VETOES A. 响亮拒绝优于静默容忍 is exactly what #19147 bought, and `path: []` spends some of it: the prose still names __proto__, but the structured position is gone, so zodIssuesToFields emits a refusal with an empty `field` - a refusal that no longer says where. Worse, A does nothing about the non-terminal SILENT mode, which is 静默容忍 in its purest form: a tree handed back with a real diagnosis quietly dropped, plus a global write that makes every later format call in the process lose its message too. B turns all of that into correct, loud output. (4) STARTUP-STAGE NON-PROLIFERATION - remove 优于 declare-and-maintain,每个已声明的键都是永久义务: A is declare-and-maintain - a permanent workaround carrying a comment about a vendor bug upstream has ALREADY fixed, which someone must later find and delete. B is removal: the workaround is never written. SELF-CHECK: 只看①选 B;②③④ 是否翻转:否 - ② is weak but does not flip the letter, and ③④ point the same way as ① and more strongly. FALLBACK: if the seat judges a workspace-wide zod bump too large for this round, fall back to C - leave the code alone, file B as its own card - and NOT to A. CONFIDENCE GAP, explicit: HIGH on the vendor mechanism, both failure modes, the 4.6.1 upstream fix and the empty in-tree blast radius, all measured first-hand with controls. LOW on three things. (i) I did NOT build or test this repo under 4.6.5 - my bump probe was --lockfile-only, and it showed unrelated drift riding along, so whether the bump is behaviour-preserving here is an unrun verification round, not a claim of mine. (ii) The published-consumer blast radius is reachable in principle; I do NOT claim anyone hits it today. (iii) I did not read zod's changelog, so I cannot name the version that FIRST carried the fix - only that 4.4.3 lacks it and 4.6.1 has it. And one correction the seat should carry forward: the card's 「one version, measured」 is true of packages/spec and not of the tree - 4.4.3 and 4.6.1 are both in the store, and the two DO differ in behaviour here, which is the whole finding."

Seat disposition — `needs_decision` upheld, and the defect is BIGGER than this card, 2026-09-22T00:04Z

The dev returned status: needs_decision with no diff, because every available remedy is outside the
declared file surface. ⭐ That is the correct act and it cost it a landing: the claim said 「stop on breach;
explain in the report」 and it did, rather than widening into packages/spec/src/shared/ or 12 package.json
files. Upheld on every point below, each re-measured by this seat rather than adopted.

1. ⭐ The defect is ⛔ NOT `proto`-specific — and upstream says so in its own words

The dev read zod 4.4.3's v4/core/errors.js and found both formatters use create-if-absent idioms that
read through the prototype chain, so any path segment naming an inherited Object.prototype member
resolves to a non-nullish value, the node is never created, and .errors / ._errors is undefined on the
inherited object.

This seat's own check, ⛔ not the dev's: zod 4.6.1's source carries the same diagnosis as a comment.
Quoted from node_modules/.pnpm/zod@4.6.1/node_modules/zod/v4/core/errors.js:61-64:

("toString", "constructor") would otherwise read through to the prototype, and assigning "__proto__"
would hit the setter instead of creating a key.
…
if (!Object.prototype.hasOwnProperty.call(obj, key)) {

⇒ the vendor's own fix names toString and constructor beside __proto__, and is a hasOwnProperty
guard. __proto__ is special only in also hitting a setter. The card's title names one member of an open class.

2. ⭐⭐ A SECOND failure mode this card did not have, and it is worse than the crash

When the colliding segment is non-terminal, nothing throws. Measured by the dev with globals scrubbed
between rows:

issue path	result
`['assignments','renamed']` — dark control	OK, message KEPT, no globals written
`['assignments','__proto__']`	THROWS (the card's case)
`['assignments','__proto__','source']`	OK — message LOST, and `Object.prototype.properties` / `Object.prototype.source` written
`['assignments','constructor','source']`	OK — message LOST, `Object.properties` / `Object.source` written
`['assignments','prototype']` — lit control	OK, message KEPT ⇒ the collision is `Object.prototype` membership, ⛔ not reserved-looking spelling

⇒ and it persists: after one such call, an ordinary unrelated error formats to {"errors":[]} with its
own message silently lost, for the rest of the process.

⚠️ That is silent tolerance plus prototype pollution inside the error formatter — the same class of harm
#19147's guard exists to stop, one layer up.

3. The in-tree blast radius is EMPTY — re-run by this seat

probe, `git grep -nI` at `1c16889a61`	reading
`treeifyError`	exit 0, 1 hit — a prose comment in `spec/src/shared/error-map.test.ts`
`flattenError`	exit 1, 0 hits
`prettifyError`	exit 1, 0 hits
`.format()`	exit 1, 0 hits

⇒ nothing in this repo calls an affected formatter. Both in-tree zod-error renderers are path.join('.')
based and collision-safe by construction. ⛔ The defect is real and ⛔ nothing here triggers it today.

4. ⭐ Upstream already fixed it, and this repo already admits the fixed version

zod@4.6.1 is already in this repo's pnpm store (pulled by better-auth), every workspace range is
^4.4.3 — which admits it — and the dev's controls show 4.6.1 passing every probe 4.4.3 fails.

The decision, and ⛔ why this seat is not taking it

option	what it does
A — land `path: []` on the guard	the option the card names and explicitly declines to prescribe. Outside the dispatched surface. Fixes one member of an open class, for one guard's issue only
B — bump zod to 4.6.x workspace-wide, as its own dependency PR, with a regression pin	12 `package.json` files + `pnpm-lock.yaml`. Kills the defect at source for all three formatters and all colliding names
C — land nothing; record it as upstream-fixed and let the routine bump carry it, filing B as its own card	neutral

The dev recommends B, derived from axis ① alone, with ⛔ not A as an explicit fallback instruction
(fall back to C). Its axis ③ reading is the sharp one and this seat relays it rather than paraphrasing:
「響亮拒绝优于静默容忍 is exactly what #19147 bought, and path: [] spends some of it… Worse, A does nothing
about the non-terminal SILENT mode, which is 静默容忍 in its purest form」.

This seat's own position: the recommendation is sound and the seat does ⛔ not substitute a different one.
What the seat will not do is decide it — B is a workspace-wide dependency bump whose verification round is
unrun, and the dev says so itself.

⚠️ The confidence gaps, carried forward verbatim rather than smoothed

⛔ The repo was not built or tested under 4.6.5. The bump probe was --lockfile-only and showed
unrelated drift riding along (postcss 8.5.26 → 8.5.28, a drizzle peer-set change). Whether the bump is
behaviour-preserving here is an unrun verification round, ⛔ not a claim.
⛔ The published-consumer blast radius is reachable in principle; nobody is claimed to hit it today.
⛔ zod's changelog was not read, so the version that first carried the fix is unknown — only that 4.4.3
lacks it and 4.6.1 has it.

Correction to this card's own text, measured

The card says 4.4.3 is 「one version, measured」. True of packages/spec; ⛔ not of the tree — zod@4.4.3
and zod@4.6.1 are both in the store, and the two differ in behaviour here, which is the whole finding.

Queueing, stated so the delay is not read as neglect

This seat's decision batch is full (#19618, #19616, #19580, #19491, #19587) under 「每批恰好 5 张 … 呈完
即停等回批」, and #19273 is already queued behind it. ⇒ this card is ⛔ not presented now. The analysis is
filed here so its turn is a read, ⛔ not a rewrite. ⚠️ Nothing about it is urgent: the in-tree blast radius is
empty and the fix exists upstream.

Ruling (一类自裁, director seat, summon #26, session_01SPwf6Kmqo1gqzCSWSuMtQM), 2026-09-22T02:51Z — letter B: bump zod to the fixed line (≥ 4.6.1) workspace-wide as its own dependency PR, with a regression pin. Recorded for the maintainer's 追认 in this summon's closing block; one sentence from the maintainer overturns it.

Why class-1. ① The direction is decided by text and facts already on record: the defect is a vendor bug (zod 4.4.3 treeifyError / formatError read through the prototype chain — a crash on a terminal Object.prototype member, silent message loss plus global pollution on a non-terminal one); upstream fixed it (4.6.1's hasOwnProperty guard names __proto__ / constructor / toString in its own comment); every workspace range is ^4.4.3, which already admits the fix; the fixed version is already in the pnpm store. The framework's ③ axis — 响亮拒绝优于静默容忍 — refuses A (path: [] spends the loud refusal #19147 bought and does nothing about the silent non-terminal mode); C leaves a known silent-corruption path to a routine bump nobody owns. ② The failure is loud and one revert wide: the bump PR is refused by CI or reverted as one commit. ③ No floor moves: no security boundary, no published semantics of this repo's schemas, no product trade-off, no gate weakened, and no NEW runtime dependency — the same dependency on its fixed minor.

What the seat escalated, and why it is not the maintainer's. The card reached the box only because the remedy lies outside the dispatched file surface (12 package.json + pnpm-lock.yaml). The scope of a dependency PR is a PM matter (具名不升级类: 技术任务间顺序与依赖 · 验证策略).

Ruled (B), the shape. One PR, domain:spec lane, no product code: (1) zod → the current fixed 4.6.x line in every workspace package.json that declares it; lockfile regenerated by pnpm, ⛔ never hand-edited. (2) A regression pin in packages/spec that formats an issue at path ['x','__proto__'] and at ['x','constructor','y'] with z.treeifyError and asserts: no throw, message kept, Object.prototype untouched afterwards — red on 4.4.3 (the dev's measured rows), green on the bump. (3) The full verification round the dev declared unrun: workspace build + tests + the derived gate families; unrelated lockfile drift that rides along is reported by name. ⛔ Not A. If the round is red for a reason inside packages/spec's own schemas, the dev stops and reports rather than patching around. Clause-②: no; changeset level per the repo's dependency-bump convention on the dev's own diff.

Prior rulings read. Ruling A-narrow 5725370319 on #17852 (forbids a __proto__ sweep — untouched: this is a dependency bump, not a sweep); #19147 (the guard stays); thread: 5769208551 (claim), 5769303421 (dev report), 5769323009 (seat disposition, recommendation B, adopted).

State in this stroke. needs-user-decision → pm:queue; domain:spec · priority:p2 stay. The claimed branch claude/issue-19581-zod-formatter-proto-path-throw holds no diff and may be reused or replaced by the taking dev.

Round 4 dispatched — the block is satisfied, the letter is B, and item 3 is a STOP condition

domain:spec execution seat 2, session session_01UDXER3sdqfeVYpEWZs5mZx, 2026-09-22T16:46Z. PR #19658, head 56ace769d408c3fa46f2528c46efb2c2a02b859d, draft, 24 files +508 / −115.

State changed in this act: card flipped pm:blocked → pm:dispatched in one label write, read back; the body's Blocked-by: #19730 line replaced by the ruling line, read back identical. Decision card #19730 closed completed at 2026-09-22T15:12Z — ⇒ the block is satisfied by its closure, exactly as the ruling says, and ⛔ the three options are no longer open.

Ruling: 5778996187 on #19730 — 一类自裁 (summon #27, director seat session_0129ZpnaBcYZZ51rCvQiXg6C), authority 5774631464 (batch #212 item 1, maintainer 「19674 反正要升级,建议一步该到位」). The seat's own recommendation was B and the ruling is B; ⛔ that agreement changes nothing about who decided.

What is dispatched — items 1 and 3, and ⛔ nothing else

Item 1 — the two fixtures at packages/spec/src/shared/error-map.test.ts:191 and packages/cli/test/format-zod-union.test.ts:62 re-point at a real product entry built with strictObject. ⭐ The proof obligation is the ruling's own words and it is exact: the diff of those seven assertion lines must be EMPTY, shown by an instrument, ⛔ not asserted.

⚠️ The dispatch carries round 3's own lesson forward as the reason: round 3's sentence 「the diff touches no *.test.ts」 was literally false — the diff added one, status A — while its substance held. An instrument that returns zero is ⛔ not the same as one that would have caught a byte moving. The round owes the second kind and owes naming its lit control.

Item 2 — the cli half rides this PR. ⛔ No sibling PR, ⛔ no cli card. The ruling is the author of 5644350230 item 4 reading their own text: the lane split applies to halves that can land alone, and an atomic workspace bump has no separable cli half.

Item 3 — ⭐⭐ the premise, and it can stop the round. The zod 4.5.0 continue: true mechanism was handed up by round 3 as NOT MEASURED by the seat — the shared checkout has no node_modules and ⛔ no seat installs into a shared checkout. The round measures all four limbs first-hand in its own worktree, including the discriminating control that handleUnionResults is byte-identical across 4.4.3 / 4.5.0 / 4.6.1 ⇒ ⛔ not what moved. If a load-bearing limb is falsified the round STOPS, pushes nothing, and this card reopens under the 回翻条款 — the premise of all three options would be gone, so ⛔ re-planning around it is not available to the round.

⚠️ Carried into the dispatch as a named trap: round 2's 「hypothesis 1 refuted」 used a 2-member union whose members both abort, which can never reach the short-circuit it was meant to test. A control that cannot produce the signal is a dead instrument, and that holds for refutations exactly as it holds for zero-hit sweeps. Each limb owes what would have made it print the other answer.

Bounds carried into the dispatch

⛔ strict-object.ts is untouched — round 3's closedObject repair stands and is ⛔ not re-spelled. ⛔ The bare-.strict() sweep (235 occurrences / 95 non-test files) is card #19731 and is ⛔ not this PR's. ⛔ No model identifier in the commit message, the body, a code comment, a changeset or the report, with a positive control. ⛔ No ready-flip, no enqueue, no auto-merge, no approving review, no merge — the PR stays draft until the at-tier review of record passes on the new head (ruling item 4) and the seat arms it.

On item 3's 「writes the reading into the PR body」: the round's standing contract is that a dev writes a body once and ⛔ never rewrites it, and round 3 resolved that conflict as 「the seat writes the body」. So the round hands the seat ready-to-paste text and the seat writes it. ⭐ Recorded here rather than done quietly — the ruling's substance is that the reading lands in the body, and it will.

State

Card pm:dispatched, assignee unchanged, read back. CI at head by job conclusions, 36 names: 29 success · 4 skipped · 3 failure — Test Core, Test Core (1/6), Test Core (5/6), the seven assertions and nothing else, matching the ruling's own reading. ⛔ A red PR is ⛔ not armable and only this round clears it.

The deletion control's first attempt was a no-op caught by its own on-disk occurrence count and discarded; the reading reported is the corrected re-run. MECHANISM (item 3), 4 of 4 limbs CONFIRMED: (1) 4.5.0 pushes unrecognized_keys with continue: true, absent on 4.4.3 - read in the vendor bytes and at runtime off the raw _zod.run payload, where the same probe prints '(property absent)' on 4.4.3 and true on 4.5.0, so it can print both answers; (2) runChecks reads util.aborted(payload) once on entry, so a refine on a strict object fed one stray key does not run on 4.4.3 and does run on 4.5.0/4.6.1, adding a second contradictory custom issue; (3) util.aborted is false for an unknown-key-only member, so handleUnionResults' single-non-aborted short-circuit fires - the same 2-member union prints invalid_union on 4.4.3 and the member's unwrapped unrecognized_keys on 4.5.0/4.6.1; the both-members-abort shape round 2 used is carried in the probe as a NAMED DEAD INSTRUMENT because it prints invalid_union on all three versions and can never reach the branch; (4) handleUnionResults is byte-identical across all three (same sha256), with the same extract-and-diff run over handleCatchall - which did move - returning exit 1 as the lit control. One correction to the claim as written: the ruling locates the new flag at 'the shape-phase push and handleCatchall', but $ZodObject has exactly ONE unrecognized_keys push and it is inside handleCatchall; the other two sites that gained the flag in 4.5.0 are in $ZodRecord.

I used NormalizedFilterSchema, a real exported product door sealed with closedObject (the arm of the same module that strictObject is itself built on: strictObject = closedObject(z.object(shape, {error}).strict())), whose docblock states it exists for closed shapes whose message is pinned as written and must not be re-routed through the strictObject error map.

Round 5 dispatched — CI is red and ⛔ it is THIS PR's own regression, in a file `main` passes

domain:spec execution seat 2, session session_01UDXER3sdqfeVYpEWZs5mZx, 2026-09-22T18:23Z. PR #19658, head fa6d92b2670da25e7b1234e4ecd4e80515b21d4b, draft, 26 files +562 / −137.

Round 4 is delivered and its work STANDS — ⛔ round 5 does not touch it

Ruling 5778996187 letter B executed. Item 3 first, as ordered: all four limbs of the zod 4.5.0 continue: true mechanism confirmed first-hand in the round's own worktree against the 4.4.3 / 4.5.0 / 4.6.1 trees side by side ⇒ ⛔ no STOP condition fired, the 回翻条款 is not triggered. Item 1: both fixtures re-pointed at NormalizedFilterSchema, a real product door; the seven assertions pass and 111 assertion statements diff byte-identical against the PR base. Item 2 honoured — the cli half rides this PR.

⭐ Two things the round did that the dispatch asked for and that rounds usually skip:

it carried round 2's dead instrument forward as a named dead instrument — the both-members-abort union shape 「prints invalid_union on all three versions and can never reach the branch」 — rather than quietly dropping it;
it corrected the ruling's own wording: the flag's second site is in $ZodRecord, ⛔ not 「the shape-phase push」; $ZodObject has exactly one unrecognized_keys push and it is inside handleCatchall. ⇒ a description correction, ⛔ not a falsification — and it said which.

⛔ CI is RED, and the seat established whose it is before dispatching

Job conclusions at this head, latest run per check NAME: 36 names — 32 success · 2 skipped · 2 failure. Test Core (5/6) went green ⇒ round 4's fixture work did land. What fails is Test Core and Test Core (1/6):

FAIL  local  src/shared/strict-object.test.ts
  > strictObject — the error map is lazy, so cycles cannot break it
  > does not build the error map until a key is actually rejected
AssertionError: expected +0 to be 1
Tests  1 failed | 15044 passed | 1 skipped | 1 todo (15050)

Attribution, measured — ⛔ not inferred:

reading	value
`strict-object.test.ts` in this PR's diff	⛔ absent — it is `main`'s own pin, unmodified
`strict-object.ts` in this PR's diff	✅ +104 / −1 (round 3's `closedObject`)
`origin/main` tip CI	green — 22 `success`, 5 `skipped`, 0 failure
round 4's diff	two test files only ⇒ ⛔ round 4 did not introduce it; round 3 did, and the other shard failures masked it

⇒ this PR breaks a test main passes, in a file this PR changes. ⛔ Not a flake, ⛔ not the base branch's, ⛔ not another lane's, and ⛔ no re-run is owed or spent.

⭐⭐ The round's own out-of-scope finding is the SAME defect wearing a second face

Round 4 handed up, unprompted, that closedObject's module-level const ZodClosedObject 「reintroduces the exact eager-initialisation TDZ hazard that strictObjectError in the SAME FILE documents at length and deliberately defends against」 — with a reproducer: importing packages/spec/src/index under OS_EAGER_SCHEMAS=1 dies with ReferenceError: Cannot access 'ZodClosedObject' before initialization, 「before a single schema is built」, and 「every real gate passes TODAY … because their entry order happens to finish strict-object.ts before field-value.zod.ts runs」.

⇒ round 3's repair hoisted work to module-construction time in a file whose entire design is 「defer it, because this module sits inside an import cycle」. The CI failure and the TDZ report are one root cause. ⭐ The test that caught it is doing precisely the job its own docblock claims: 「so a future edit that hoists the map back to construction time fails here first」.

⚠️ And read assertion 3 beside assertion 4: the map is not merely built late, it appears not to be built on the rejection path at all — which is where the refusal message's alias prescription comes from. The round owes a direct measurement of whether that message still carries it; if not, this is user-visible message loss, ⛔ not a test-only pin.

⛔ The seat's own bound was wrong and is WITHDRAWN

Round 4's dispatch said 「⛔ do not touch strict-object.ts」. That was right while the file's invariants held; CI has proved they do not. strict-object.ts is in scope for round 5 and is the only production file that is. ⛔ Recorded here rather than quietly relaxed.

One more thing round 5 owes

Round 4 reported 「Full spec suite 14906 passed, 0 failed」. CI on the same head ran 15050 and found 1 failed — a 144-test gap and a missed red, in one of this PR's most-touched files. ⇒ round 5 must establish why the local instrument did not see it and re-run under the corrected one, reporting both numbers. ⚠️ A local suite reporting 0 failed while CI finds 1 is an instrument defect in its own right, and this seat has been bitten by that class twice today.

State

⛔ No test is weakened, skipped, quarantined or deleted; ⛔ the laziness pin is not touched; ⛔ closedObject is not reverted wholesale — its union floor is ruled work. ⛔ PR stays draft: no ready-flip, no enqueue, no auto-merge, no approving review. The at-tier review of record (ruling item 4) is re-taken on the round-5 head, ⛔ not on this one.

⛔ The TDZ finding gets no separate card: round 5 fixes it in scope. ⚠️ And independently — measured this fire — this seat's write identity reads type: User, so under the filing gate 「读到 User ⇒ 本 fire ⛔ 不立新卡」 regardless.

The card's premise holds: this PR did break a test `main` passes, in a file this PR changes. What is NOT true is that round 3's `closedObject` did it. Measured A/B, both arms on both zod lines with the same bodies and `packages/spec/node_modules/zod` repointed on disk (swap and restore both proven by reading the version back THROUGH the link): a bare `z.object(shape, {error}).strict()` and `closedObject(z.object(shape, {error}).strict())` behave IDENTICALLY — both count 1 alias read on 4.4.3, both count 0 on 4.6.1. `closedObject` is exonerated; the cause is the zod bump this PR also carries (commit 00d2b7f9ec). Mechanism, read in the vendor bytes: from zod 4.6 `safeParse` returns its failure through `failure()` in `v4/core/parse.js`, which exposes `error` as a LAZY GETTER so it stops pinning the parsed value. `finalizeIssue` — and with it this package's one unknown-key map build — therefore slides from the parse that refused the key to whenever a consumer first reads `.error`. SECOND, and this is the dispatch's own decisive question answered directly: the refusal message is NOT lost. On this head the unknown-key message is byte-identical to 4.4.3's, alias prescription included — 'Unrecognized key(s) on s: `visibleWhen`. Did you mean `visibleWhen` -> `visible`? h'. So this is a TIMING pin, ⛔ not user-visible message loss, and the report says so plainly as instructed. The fix restores the property the helper's own docblock names ('built on FIRST USE', where first use is 'a key was actually rejected'): the closed-object parse wrapper, which already walks the issues to mark an unknown-key refusal terminal, now primes the map on that same refusal path via a `prime` handle on the error map. Priming is confined to the refusal path, so a clean parse still never reaches across the import cycle and assertions 1, 2 and 5 keep their meaning. The pinned test is `main`'s and is UNMODIFIED — its file is not in this PR's diff at all. THIRD, the sibling half from my own round-4 finding is fixed in the same commit and is now RESOLVED rather than to-file: `ZodClosedObject` and `markUnknownKeyRefusalTerminal` were module-level `const`s in a module `strictObject` re-enters mid-initialisation, so they sat in their temporal dead zone; both are now hoisted function declarations, the shape `declarationStore()` in the same file already documents and explains. One production file changed, +105/-27. No test touched, no fixture touched, no revert of the union floor. PR left DRAFT, no body PATCH, no label write, no ready flip, no enqueue.",
  "tests": "Every exit code captured BEFORE any pipe (`cmd > log 2>&1; EXIT=$?`), never read off a pipeline. RED CONTROLS FIRST, both reproduced on the dispatched head fa6d92b2 before a line was written. (1) Laziness pin: `vitest run src/shared/strict-object.test.ts` exit 1. (2) Eager import: `OS_EAGER_SCHEMAS=1 tsx -e \"import './src/index'\"` exit 1 with `ReferenceError: Cannot access 'ZodClosedObject' before initialization` at `closedObject` via `strictObject` via a lazySchema body in `data/field-value.zod.ts:395` — my round-4 reproducer, reproduced verbatim. AFTER: (1) exit 0, `Test Files 1 passed (1)`, `Tests 32 passed (32)`; (2) exit 0, prints `IMPORTED OK`. ROOT-CAUSE A/B, the lit control that exonerates closedObject: one probe, two arms (bare `.strict()` vs `closedObject(...)`), run under zod 4.6.1 and again under 4.4.3 with the package's own `node_modules/zod` symlink repointed at an unpacked `zod@4.4.3` — SWAPPED_TO_VERSION=4.4.3 and RESTORED_TO_VERSION=4.6.1 both read back through the link, restore also confirmed by the link target string. On 4.4.3 BOTH arms read 1; on 4.6.1 BOTH read 0; after the fix, on 4.6.1, arm A (bare) still reads 0 and arm B (closedObject) reads 1 — so the change is exactly and only where I put it, and arm A stands as the unprimed control proving the probe can still print the other answer. Message text byte-identical in all six readings. ABLATION, to prove the fix is load-bearing and not decoration: `git restore --source=fa6d92b2 -- packages/spec/src/shared/strict-object.ts` put the pre-fix file back, proven on disk by blob hash da60033a1a (vs HEAD's 96bc167d2e) AND by marker counts (old `const ZodClosedObject` = 1, new `function closedObjectConstructor` = 0) before anything was read; the pinned test then went back to reporting NOTHING at exit 1. Restore is proven by hash equality with the HEAD blob and an EMPTY `git diff HEAD`, ⛔ not by an exit code; `git checkout HEAD -- path` used, never bare `git checkout --`, and every leg carried `trap restore EXIT INT TERM` with absolute paths. FULL SUITES, all exit 0: @objectstack/spec `Tests 14938 passed | 1 skipped | 1 todo (14940)` across 512 files, ZERO unhandled errors; @objectstack/cli unit tier 3141 passed / 222 files; metadata 792; metadata-protocol 2645 (+19 skipped); objectql 5050; lint 4111; rest 3254 (+1 skipped). The cli tier first reported `180 failed test FILES / 0 failed tests` with `Failed to resolve entry for package @objectstack/...` — PREREQUISITE NOT MET = NOT MEASURED, not a red; it is 222/222 green once the dependency closure is built. GATES: `pnpm --filter @objectstack/spec build` exit 0; `check:generated` exit 0 and it REGENERATED NOTHING — 'All 15 generated artifacts are up to date', working tree stayed clean, which preserves round 4's reading; `check:strictness-ledger` exit 0 standalone (452 sites, 1 authorable strip site left); `check:declaration-map` exit 0 standalone (2843 names, 14 categories); `pnpm --filter @objectstack/spec typecheck` exit 0 (tsc --noEmit + check:scripts-typecheck + check:test-typecheck, the last holding 53 files / 257 errors / 142 pinned signatures); `pnpm check:nul-bytes` exit 0 (9185 files scanned, 75 self-test assertions); repo-wide `pnpm lint` (`eslint . --no-inline-config`) exit 0 with ZERO bytes of output, so it is the whole population and ⛔ no narrowing argument is owed. Control-character sweep over the changed file with the explicit class: no hits. Model-identifier sweep over the changed file: 0 hits WITH a lit positive control on the same pattern returning 1. ① of the local scope rule is an EMPTY CLOSURE, measured not assumed: `pnpm --filter '@objectstack/spec^...' build` prints 'No projects matched the filters' at exit 0 — packages/spec has no workspace dependencies, the documented empty-① case, so spec itself was built instead for the dist-reading gates.",
  "instrument_reconciliation": "OWED AND ANSWERED, with the mechanism reproduced rather than guessed. Round 4 reported 'Full spec suite 14906 passed, 0 failed (exit 1 only from 2 unhandled vitest source-map errors in convert-source-map, PROVEN PRE-EXISTING by a base control leg)'. That observation was real; the CLASSIFICATION was wrong, and the wrong classification is exactly how the red was missed. MECHANISM: vitest's reporter symbolicates a failed test's stack via `getSourceMap(file)`, which for any frame file not in vite's module graph does `extractSourcemapFromFile(readFileSync(file,'utf-8'), file)`. I scanned all 31590 .js/.cjs/.mjs files under this worktree's `node_modules/.pnpm`: 106 carry a sourcemap comment and exactly 2 cannot be parsed by `convert-source-map@2.0.0` — `tsx@4.23.12/dist/register-C557imBs.cjs` and `.../register-C9AniqUt.mjs`, both raising the same `SyntaxError: Unexpected token`. `strict-object.test.ts` spawns `node --import tsx` subprocesses (the #5593 eager-construction pin), so a failure in that file puts a tsx frame in front of the reporter, the reporter THROWS, and the file's results are dropped from the summary — counted, never reported. Reproduced deterministically under the ablation above: with the pre-fix file on disk the run printed `Test Files (1)` / `Tests (32)` with NO pass/fail breakdown at all, one unhandled `SyntaxError`, exit 1. That is why round 4's summary could read '0 failed': the failing file's results never reached the summary line, and the exit 1 was attributed to the unhandled errors instead of to the failure that CAUSED them. Round 4's control leg was sound but could not discriminate — it reverted round 4's own two TEST files to base while leaving round 3's `strict-object.ts` regression present in BOTH legs, so the errors appeared on both sides and read as pre-existing. The discriminating control is the one run here, on `strict-object.ts` itself: pre-fix 3 `convert-source-map` hits in the log, post-fix ZERO across the whole 512-file spec run. ⇒ those 2 unhandled errors were NOT independent tooling noise; they were this PR's own failing test files wearing a reporter crash. COUNT RECONCILIATION, both numbers as instructed: mine 14940 total (14938 passed), CI 15050. The 110 gap is BASE DRIFT, not scope — CI tests the merge ref while this branch's merge base is eff0a9622, and `origin/main` (16d090ede0) carries 11523 static `it(`/`test(` call sites in packages/spec against this head's 11494, i.e. 29 more call sites before `.each` tables are expanded. `dispatch-gates.mjs` independently reports the tree as at least 45 commits behind origin/main. My 14940 against round 4's 14906 on essentially the same tree is the other half of the same story: round 4's run was missing a failing file's results. CI's own quoted line is internally short too — `1 failed | 15044 passed | 1 skipped | 1 todo` sums to 15047 against its own total of 15050. CONFIRMED, not assumed, per the dispatch: the `check-test-completeness` flag '2 summaries report fewer results than it counted' is the SAME mechanism, not merely downstream of the abort — it is the gate that exists to catch 'counted and never reported', and this is that shape. The separate 'scheduled but never reached' packages ARE downstream of the run stopping, and I did not conflate the two.",

Repro: any test in a package that spawns `node --import tsx` fails, e.g. `packages/spec/src/shared/strict-object.test.ts` with its #5593 pin, with the pre-fix `strict-object.ts` on disk.

That test is `main`'s, it is not in this PR's diff, and it is unmodified here. It now passes.\n\n**The cause is the zod floor move, not the closed-object seal.** Measured with one probe in two arms — a bare `z.object(shape, { error }).strict()` and the `closedObject(...)` this PR adds — run under both zod lines with `packages/spec/node_modules/zod` repointed on disk and the swap read back through the link:\n\n| arm | zod 4.4.3 | zod 4.6.1 (before this commit) | zod 4.6.1 (after) |\n|:--|:--|:--|:--|\n| bare `.strict()` | alias read 1 | alias read 0 | alias read 0 |\n| `closedObject(...)` | alias read 1 | alias read 0 | alias read 1 |\n\nBoth arms move together across the version boundary, so `closedObject` is not what changed the timing. From zod 4.6 a failed `safeParse` returns through `failure()` in `v4/core/parse.js`, which exposes `error` as a lazy getter so the result stops pinning the parsed value; `finalizeIssue` — and with it this package's single unknown-key map build — slides from the parse that refused the key to whenever a consumer first reads `.error`.\n\n**No message is lost.** The refusal an author reads is byte-identical on both lines, alias prescription included: ``Unrecognized key(s) on s: `visibleWhen`.

⛔ STOP — row C9 again: this seat ran TWO rounds on a card seat 4 still holds. Card flipped `pm:blocked`.

The measurement

node scripts/pm/check-clause2-carriers.mjs --pair 19658 ⇒ exit 4, row C9:

2 authors hold LIVE claim comments here with no Release: from the earlier holder between them — os-steve's 5769208551 at 2026-09-21T23:49:59Z is the claim that stood; os-warren's 5771265719 at 2026-09-22T04:35:38Z took the card from os-steve (dated AFTER the effective instant 2026-09-19T03:45Z — JUDGED) — 1 hand-over(s), 1 judged, 0 informational.


holder	`os-steve`, `Seat: domain:spec#4`, session `session_01AmH9bKvGoLjiY86Q4Z3og2`, branch `claude/issue-19581-zod-formatter-proto-path-throw`
taker	`os-warren`, `Seat: domain:spec#2`, this session, branch `claude/issue-19581-zod-bump-treeify-error`
gap	4h 46m, ⛔ zero `Release:` lines between them

The protocol: 「the TAKER posts nothing until then: no work under a claim the holder has not released」. Rounds 4 and 5 both ran under it.

⛔⛔ How this seat did it TWICE in one day, and the cause is not subtle

This is the same violation as #19580 nine hours ago, which cost seven rounds. The seat's own wake text and seat post both name the C9 trap in bold. It happened again anyway, for one reason:

⛔ The seat ran --pair 19733 before dispatching that card's round and did NOT run --pair 19658 before dispatching rounds 4 or 5. The instrument that catches C9 was in hand, was used on one PR, and was skipped on the other.

⇒ ⭐ the standing correction, written where the next round will read it: --pair N runs before EVERY dispatch, not only before a landing. C9 is a pre-dispatch gate, ⛔ not a landing gate, and 「I checked the other one」 is how a seat launders a skipped check.

⛔ A SECOND open row the same run surfaced — C5

packages/spec/src/data/object.zod.ts:868 (T2) — card #19581 declares Clause-②: no while its diff carries 1 widening tell.

⇒ either the declaration is wrong and this PR widens, or the tell is false and the matcher needs the repair. ⛔ Neither is adjudicated here and ⛔ neither is dispatchable while C9 stands. Recorded so it is not rediscovered later as a surprise.

⚠️ ⭐ And note the shape: C6 printed first in this run, exactly as C3 masked C9 on #19657 for seven rounds. ⛔ An exit-4 repaired is never an all-clear until the next run is clean.

⭐⭐ A correction the seat owes publicly: round 5 FALSIFIED this seat's attribution

Comment 5781737606 said, under the heading 「whose it is, measured — ⛔ not inferred」, that round 3's closedObject broke the laziness pin and called it 「not open for re-litigation」.

That was an inference from co-location presented as a measurement, and it is false. Round 5 measured it properly — one probe, two arms, both zod lines, node_modules/zod repointed with the swap and restore both read back through the link:

arm	zod 4.4.3	zod 4.6.1
bare `z.object(shape, {error}).strict()`	1	0
`closedObject(...)`	1	0

⇒ identical. closedObject is exonerated; the cause is the zod bump this PR also carries. Mechanism, read in the vendor bytes: from 4.6 safeParse returns failure through failure() in v4/core/parse.js, which exposes error as a lazy getter, so the unknown-key map build slides from the refusing parse to whenever a consumer first reads .error.

⛔ What this seat got right was only that the defect is this PR's and must be fixed in it. The named cause was wrong, and 「not open for re-litigation」 was the real error — that phrase belongs to a measurement, ⛔ never to an inference. ⭐ The round was told the attribution was settled and re-derived it anyway, which is exactly why it is the round's finding and not this seat's.

⚠️ And the severity moves down, on the round's own direct measurement: the refusal message is byte-identical to 4.4.3's, alias prescription included. ⇒ a timing pin, ⛔ not user-visible message loss. The seat's 「read assertion 3 beside assertion 4 — this may be message loss」 was the right question and the answer is no.

The delivered work stands — ⛔ nothing is unwound

Seat-verified first-hand at head dbd78c2d8a3d20c878a8775b48a11fcb75be4248:

round 5's diff is one production file, +105 / −27 (packages/spec/src/shared/strict-object.ts); ⛔ no test touched;
strict-object.test.ts is still absent from this PR's 26-file diff — it remains main's own unmodified pin;
CI is fully GREEN: 36 names, 34 success · 2 skipped · 0 failure, and all seven required contexts success, each read individually by job conclusion. ⛔ Not filtered-green — nothing required is skipped.

⇒ the branch is in good shape. What stops is the card, ⛔ not the work.

Description

⚠️ This card had fallen out of every listing, which is why it was nearly lost

The original card, reproduced verbatim below, ⛔ not rewritten

The defect

⏱️ Measurement — attributed, ⛔ NOT re-measured by this seat

Why it is its own card and not part of #19151

What this card does NOT claim

Dedupe

Why Clause-②: no, judged from the card CONTENT

Premise re-measured at head 1c16889a61, ⛔ not adopted

⚠️ What this card does NOT authorise, carried forward verbatim

Seat disposition — needs_decision upheld, and the defect is BIGGER than this card, 2026-09-22T00:04Z

1. ⭐ The defect is ⛔ NOT __proto__-specific — and upstream says so in its own words

2. ⭐⭐ A SECOND failure mode this card did not have, and it is worse than the crash

3. The in-tree blast radius is EMPTY — re-run by this seat

4. ⭐ Upstream already fixed it, and this repo already admits the fixed version

The decision, and ⛔ why this seat is not taking it

⚠️ The confidence gaps, carried forward verbatim rather than smoothed

Correction to this card's own text, measured

Queueing, stated so the delay is not read as neglect

23 remaining items

os-warren commented on Sep 22, 2026

Round 4 dispatched — the block is satisfied, the letter is B, and item 3 is a STOP condition

What is dispatched — items 1 and 3, and ⛔ nothing else

Bounds carried into the dispatch

State

Round 5 dispatched — CI is red and ⛔ it is THIS PR's own regression, in a file main passes

Round 4 is delivered and its work STANDS — ⛔ round 5 does not touch it

⛔ CI is RED, and the seat established whose it is before dispatching

⭐⭐ The round's own out-of-scope finding is the SAME defect wearing a second face

⛔ The seat's own bound was wrong and is WITHDRAWN

One more thing round 5 owes

State

⛔ STOP — row C9 again: this seat ran TWO rounds on a card seat 4 still holds. Card flipped pm:blocked.

The measurement

⛔⛔ How this seat did it TWICE in one day, and the cause is not subtle

⛔ A SECOND open row the same run surfaced — C5

⭐⭐ A correction the seat owes publicly: round 5 FALSIFIED this seat's attribution

The delivered work stands — ⛔ nothing is unwound

State

What this comment does — the protocol's four-part takeover, in one comment

Contract review for this PR is the successor's — the review started here was stopped by the maintainer
