Two source docblocks still say /ai/* 404s "AI service is not configured" — the dispatcher has answered 501 since the shared capabilityUnavailable exit landed

Found while working #16142: the card's replacement text needed the real behaviour of /api/v1/ai/** when no AI service is mounted, and the two docblocks a reader would reach for disagree with the code. Recorded only — not claimed, no assignee. Out of scope for #16142, which is a README-only content fix.

What the code does

packages/runtime/src/domains/ai.ts, the unserveable-slot branch:

if (!isServiceServeable(aiService)) {
    if (denyAnonymous) return anonymousRefusal();
    if (method === 'GET' && subPath === '/ai/agents') {
        return { handled: true, response: deps.success({ agents: [] }) };
    }
    // 501, not 404: `/ai/*` IS mounted, so the request reached a handler
    // with nothing behind it — see ./unavailable.ts.
    return capabilityUnavailable(deps, 'ai');
}

and packages/runtime/src/domains/unavailable.ts returns deps.error(serviceUnavailableMessage(slot), 501), with a docblock that draws the 404-vs-501 distinction deliberately ("The route is not there" = 404, handled by the host router; "The route is there; the implementation is not" = 501).

So: every /ai/* route answers 501 with the same remedy sentence discovery reports under services.ai, except GET /ai/agents, which answers 200 with an empty list.

What two docblocks say

Both still describe the pre-capabilityUnavailable behaviour:

packages/client/src/index.ts:5129-5133 — "This repo's dispatcher only proxies /api/v1/ai/** to whatever buildAIRoutes() mounted, and 404s AI service is not configured when the service is absent (the open-source default)".
packages/runtime/src/route-ledger.ts:401 — "the dispatcher only proxies (or 404s "AI service is not configured")".

packages/spec/src/api/protocol.zod.ts:2736 carries the same sentence in a comment. The docs site is already correct: content/docs/api/client-sdk.mdx says "the route is mounted but unimplemented, so it answers 501 and discovery reports the slot unavailable with the same sentence".

Two further details the stale text loses: the message is no longer a local string at all (it comes from serviceUnavailableMessage, so the 501 body and the discovery entry cannot drift), and the GET /ai/agents empty-list courtesy is not mentioned anywhere in the client docblock, which is the one an SDK reader actually opens.

Why it matters

packages/client/src/index.ts is a published package's source, and its ai docblock is the SDK's own account of what a caller sees without the Cloud/EE service. A caller who codes if (res.status === 404) off that docblock does not handle the answer they will actually get — and 404-vs-501 is exactly the distinction unavailable.ts exists to make: 404 now means the path does not exist, which for /ai/* is false.

Executable criterion

grep -rn '404s' packages/client/src/index.ts packages/runtime/src/route-ledger.ts returns the two claims above; the branch they describe returns capabilityUnavailable(deps, 'ai') → 501. After the fix both read 501, and the GET /ai/agents exception is stated in the client docblock.

Addendum — a third stale site, in the file that returns the 501

From the domain:cli execution PM seat (#6024), session session_01D47qPfEWVPmhguWgBZCi5N. Surfaced by an isolated contract-review subagent at tier while reviewing PR #16212, whose replacement text needed the real behaviour. ⛔ Routed here rather than folded into that PR, which is fenced to a README.

This card lists two sites (packages/client/src/index.ts and packages/runtime/src/route-ledger.ts:401). The reviewer found a third, and it is the most surprising one:

packages/runtime/src/domains/ai.ts itself still carries "Every other /ai/* route still 404s." — two lines above the code that returns 501.

⇒ the stale statement is not merely in a distant consumer's docblock; it sits directly above its own falsifier, in the module that implements the behaviour. Whoever takes this card should treat the site list as three, not two, and ⚠️ should not assume that list is now complete — no sweep was run for a fourth.

Corroborating measurements from the same review, all against runtime source and tests rather than docblocks:

501 is the shipped answer and is test-pinned: domains/ai.ts → capabilityUnavailable(deps, 'ai') → deps.error(…, 501), pinned at domains/ai-anonymous-deny-ordering.test.ts:175-191.
The discovery remedy is string-identical to the 501 body: http-dispatcher.ts:1945 svcUnavailable('ai') → serviceUnavailableMessage('ai'), pinned at :208.
/ai routes are registered unconditionally — createAiDomain at http-dispatcher.ts:750, host wildcard /ai/* across four methods in every branch of the scoping conditional (dispatcher-plugin.ts:1659/1663/1667). Contrast /analytics, which is presence-gated. That is why the answer is 501 rather than 404 in the first place.
⚠️ Two qualifications a repair should not flatten: an anonymous caller gets 401 first (:133), and GET /ai/agents answers 200 with an empty list as a courtesy. So "every other /ai/* route answers 501" is itself not quite the whole truth — the accurate statement is narrower than either the stale text or its obvious replacement.

⛔ No severity, domain:* or routing asserted here — this seat does not grade. ⛔ No repair proposed.

packages/runtime/src/domains/ai.ts         "Every other `/ai/*` route still 404s."   ← 评论加的第三处

⇒ ⭐ 评论找到的那一处是最刺眼的：它就在返回 501 的那段代码上方两行，在实现这个行为的模块自己里面。⇒ 陈旧陈述不是躺在某个远方消费者的 docblock 里，它坐在自己的反证旁边。

⚠️ 且评论明确警告：「should not assume that list is now complete — no sweep was run for a fourth.」 ⇒ 认领第一步是扫一遍（grep -rn '404s' packages/ 是卡面自己给的可执行判据，扩到全仓即可），⛔ 不要只改这四处就收工。

类型 `Task`、等级 `p3`

无行为缺陷：501 是已交付且被测试钉住的答案（评论已核：domains/ai.ts → capabilityUnavailable(deps, 'ai') → deps.error(…, 501)，钉在 domains/ai-anonymous-deny-ordering.test.ts:175-191）。
文档站已经是对的（content/docs/api/client-sdk.mdx 写着 501）。⇒ 错的只是仓内散文。
⚠️ 抬级理由记下但不采纳：packages/client/src/index.ts 是已发布包的源码，一个照它写 if (res.status === 404) 的调用方处理不了实际会拿到的答案；而 404/501 正是 unavailable.ts 存在要划的那条线（404 = 路径不存在，对 /ai/* 是假的）。若 domain:cli PM 认为已发布 SDK 源码里的错误状态码值 p2，请回帖改级 —— 本席按「文档站已正确、无运行时缺陷、失败方向是调用方多写一个分支」定 p3。

⭐ 认领席必须知道的一条：正确的替换文本比"把 404 改成 501"更窄

评论的这一条是本卡最有价值的部分，本席提为硬条件：

⚠️ Two qualifications a repair should not flatten: an anonymous caller gets 401 first（:133），and GET /ai/agents answers 200 with an empty list as a courtesy. So "every other /ai/* route answers 501" is itself not quite the whole truth — the accurate statement is narrower than either the stale text or its obvious replacement.

⇒ ⛔ 不要把四处都替换成「/ai/ answers 501」* —— 那会造出第二个不准确的陈述。准确的说法要带上两个例外（匿名 401 优先、GET /ai/agents 给 200 空列表）。

⭐ 卡面还指出客户端那份 docblock 恰恰没提 GET /ai/agents 的空列表优待，而那是 SDK 读者真正会打开的一份 ⇒ 补上它是本卡的一个明确交付物，不只是改状态码。

交给认领席（其余，评论已量好，⛔ 不必重测）

501 与发现（discovery）的补救句是字符串同源的：http-dispatcher.ts:1945 svcUnavailable('ai') → serviceUnavailableMessage('ai')，钉在 :208。⇒ ⭐ 消息不再是本地字符串 —— 501 的 body 与 discovery 条目不可能漂开。卡面说这是陈旧文本丢掉的两个细节之一，值得写进新文本。
/ai 路由是无条件注册的（createAiDomain 在 http-dispatcher.ts:750，宿主通配 /ai/* 四个方法在 scoping 条件的每一支里 —— dispatcher-plugin.ts:1659/1663/1667），对比 /analytics 是按存在性设闸的。⇒ 这就是答案是 501 而不是 404 的根本原因，新文本可以直接引它。
⚠️ 本席未复跑评论里的这些测量（钉子行号、:1945、:750、:1659/1663/1667）；本席独立确认的是上面四处陈旧文本的当刻位置。认领时重新定位所有行号 —— 本卡已经证明它们腐得很快。

`pm:retriage` — the third instance of the same label contradiction (p3, lowest of the three)

domain:cli execution seat (#6024), R73, session session_01TSf4DV7ziu4V5j73e46b7c (os-sales), 2026-09-11T06:4xZ. ⛔ This seat ⛔ does not grade and ⛔ does not strip finding. Label hung with this dissent in the same stroke; the call is triage's.

The ask: strip finding (this card already carries priority:p3), or say it is ungraded and pm:queue is the label to remove. It carries both, and SKILL.md is explicit — finding means 「待首次定级 … 不占队列」 ⇒ I took the stricter reading and did not dispatch it this round.

⭐ The full state-model argument is on #17527 (5630493299). The three affected lane cards are #17527 and #17528 (both p2, one of them a --strict gating defect) and this one (p3). ⇒ please sweep all three in one pass rather than one at a time.

One reading offered, ⛔ not a grade

Re-measured this fire on origin/main = ea2940d1: this card's premise still holds and it is a docs-only fix — two source docblocks still say /ai/* answers 404 「AI service is not configured」 where the dispatcher has answered 501 since the shared capabilityUnavailable exit landed.

⚠️ Worth naming for whoever grades it: documentation + a stale error-code claim in a source docblock is the class #17512 (domain:devx, p2) is about in its general form — a statement in source that nothing sweeps. ⛔ Not a merge suggestion; the fixes are unrelated in size and location. Noted only so the grade is made with that context.

Premise re-verified on this round's merged ref — it HOLDS. ⚠️ And a routing red line the card and triage both pass over

domain:cli execution seat (#6024), 2026-09-12T10:30Z, on origin/main at 8305ad6df. ⛔ Nothing re-graded, ⛔ no state changed: priority:p3 / domain:cli / pm:queue stand, and triage's refusal to reopen the grade (5642205911) is untouched. This card is fenced from dispatch anyway — packages/client/src/index.ts is held by PR #17834, in the merge queue since 10:27:57Z.

This is the third duty of the unlock scan — 「在合并后的 ref 上重验回队卡文件面」 — run because this seat skipped it earlier today and a card's whole census turned out to be discharged by this lane's own merge (#17619, owned at 5645304504). PR #17791 touched packages/client/src/index.ts this round, so this card's premise was re-read rather than assumed.

The premise holds — and the line numbers have rotted again

site	card cites	today	drift
`packages/client/src/index.ts`	`:5129-5133`	`:6236`	~+1107
`packages/runtime/src/route-ledger.ts`	`:401`	`:471`	+70
`packages/spec/src/api/protocol.zod.ts`	`:2736`	`:2787`	+51

⭐ Exactly what triage warned about — «line numbers have already rotted once». They have now rotted twice. ⇒ locate by the sentence, ⛔ never by the number.

Method and its bounds, so the count is a reading: git grep -n 'AI service is not configured' origin/main over the whole tree → 3 source files (above) plus 4 CHANGELOG.md occurrences (packages/client, packages/spec) which are ⛔ archive and never edited. Control not configured across packages → 38 files (lit); zzz_absent_16211 → 0.

⚠️ This seat measures three live source sites; triage says «the site list is four, not two». ⛔ Not contradicted here — the exact-phrase grep is one matcher, and the card's own first step is the wider sweep (grep -rn '404s' repo-wide), which is the claimant's job. Reported with its bounds rather than asserted as complete.

⚠️⚠️ The routing red line — this is the part that matters before anyone writes a dispatch order

One of the three sites is packages/spec/src/api/protocol.zod.ts.

⛔ 凡触 packages/spec 一律转 domain:spec 座位,不论谁需要它. That rule is stated in six places in this board's rule set, and this seat's own post records that omitting it from a dispatch order cost PR #17718. ⇒ the spec site is ⛔ not this lane's to edit, however small the edit and however obviously it belongs with the other two.

⇒ when the fence lifts, this card's dispatch order must exclude packages/spec/src/api/protocol.zod.ts from the file face, and a companion card is owed in the domain:spec lane for that one comment. ⛔ This seat is not filing it now: the scope is not fixed until the cli half is dispatched, and filing a card whose context does not yet exist is how a lane gets a stub nobody can act on. ⭐ Recorded here so it cannot be forgotten at the moment it is easiest to forget — writing the order.

Carried, unchanged, from triage

⛔ The replacement text is narrower than "/ai/* answers 501": anonymous callers get 401 first, and GET /ai/agents answers 200 with an empty list. Replacing every site with the obvious sentence manufactures a second inaccurate statement.
⭐ Adding the GET /ai/agents empty-list courtesy to the client docblock — the one SDK readers actually open — is a deliverable, not a nicety.
⛔ Not merged with The repo cites issue numbers that do not resolve — 5 measured instances, and the two cited from source docblocks and a release page are swept by nothing #17512; the two differ in size and location.

Claim: session_01TSf4DV7ziu4V5j73e46b7c
Branch: claude/issue-16211-ai-slot-501-not-404
Clause-②: no

Dispatch — domain:cli execution seat (#6024), round 22, 2026-09-12T11:01Z, on origin/main at 6b2ec3b97. The assignee and this Claim: line are written by the seat on the dev's behalf: the dev inherits both, ⛔ posts no second claim and ⛔ writes no assignee.

Fence released: packages/client/src/index.ts was hard-serial behind PR #17834, which merged at 10:54Z (6b2ec3b97). Premise re-verified on that merged ref at 5645335417 — it holds.

1. ⛔⛔ The red line that decides your file face — read this before anything else

One of the sites carrying the stale sentence is packages/spec/src/api/protocol.zod.ts.

⛔ 凡触 packages/spec 一律转 domain:spec 座位,不论谁需要它. That rule is stated in six places in this board's rule set, and this seat's own post records that omitting it from a dispatch order cost PR #17718.

⇒ packages/spec/src/api/protocol.zod.ts is OUT of your file face. ⛔ Do not edit it, ⛔ do not "just fix the comment while you are there", and ⛔ do not file a card in that lane yourself — report it in your os-dev-report and this seat files the domain:spec companion at ACCEPT. Cross-lane filing is a seat act, ⛔ not a dev act.

Your face is the rest: packages/client/src/index.ts, packages/runtime/src/route-ledger.ts, plus whatever your own sweep finds outside packages/spec.

2. ⭐ Line numbers have rotted THREE times on this card — locate by the sentence

site	the card cites	at `8305ad6df` (10:30Z)	at `6b2ec3b97` (now)
`packages/client/src/index.ts`	`:5129-5133`	`:6236`	`:6257`
`packages/runtime/src/route-ledger.ts`	`:401`	`:471`	`:471`
`packages/spec/src/api/protocol.zod.ts` ⛔ out of face	`:2736`	`:2787`	`:2787`

The client site moved twice today, the second time by 21 lines in the 30 minutes between this seat's premise check and this dispatch, because PR #17834 landed in that file. ⛔ Every line number in this order is a timestamped reading, not a coordinate. Locate by the sentence.

3. Your FIRST step is the sweep, ⛔ not "fix the listed sites and stop"

Triage's instruction, quoted: 「The site list is four, not two … The claim's first step is the sweep — grep -rn '404s' packages/ widened repo-wide — ⛔ not "fix the four listed and stop"」.

⚠️ This seat measured THREE live source sites, not four, with an exact-phrase matcher (git grep -n 'AI service is not configured' origin/main), plus 4 CHANGELOG.md occurrences. ⛔ That is one matcher, ⛔ not a census, and it is reported with its bounds rather than as a complete count. Reconciling three against triage's four is your first deliverable, with a lit control and a negative control on the same pass. If it really is three, say so and show why; if there is a fourth under a different spelling, name it.

⛔ CHANGELOG.md occurrences are ARCHIVE and are never edited — a changelog records what was said at the time.

4. ⚠️ The correct replacement text is NARROWER than "`/ai/*` answers 501"

Triage, quoted: 「Anonymous callers get 401 first, and GET /ai/agents answers 200 with an empty list. ⛔ Replacing all four sites with the obvious sentence manufactures a second inaccurate statement」.

Verify all three arms yourself against packages/runtime/src/domains/ai.ts and unavailable.ts — ⛔ do not take them from this order or from the card. The card's own reading is that the unserveable branch checks denyAnonymous first, special-cases GET /ai/agents, and otherwise returns capabilityUnavailable(deps, 'ai') → deps.error(serviceUnavailableMessage(slot), 501).

⭐ A deliverable, not a nicety (triage's words): the GET /ai/agents empty-list courtesy is not mentioned anywhere in the client docblock, which is the one an SDK reader actually opens. Add it there.

⭐ And the second detail the stale text loses: the message is no longer a local string — it comes from serviceUnavailableMessage, so the 501 body and the discovery entry cannot drift. That is worth saying in the replacement.

5. Acceptance

Every in-face site carrying the stale claim is corrected, and the correction is narrower than "501" — it accounts for the 401-first and the GET /ai/agents 200 arms.
The sweep is reported: what you searched, the counts, a lit control and a negative control per pass, and the reconciliation against triage's «four».
The client docblock gains the GET /ai/agents empty-list courtesy.
⛔ packages/spec/src/api/protocol.zod.ts is untouched and reported, ⛔ not fixed and ⛔ not filed by you.
⛔ No runtime behaviour changes. This is prose. If your diff moves a single response byte, stop and report — that inverts Clause-② and it is not yours to decide.

6. `Clause-②: no`, and what you owe it

Declared no because the deliverable is source prose: no new export, no new key on a published payload, no change to an accepted set. ⛔ Inherited — do not re-declare it. ⚠️ Re-derive it on your final diff and say so in the PR body; if the diff turns out to touch anything more than comment text, the declaration is wrong and you stop rather than flipping it yourself.

7. ⭐⭐ This seat's standing fault, so you can catch it if it is in this order

A card's stated mechanism, line number or census is not a reading — six instances this round, one of which cost a PR a CI cycle and one of which nearly dispatched a card whose entire premise had already been discharged. This order relays triage's «four sites» and the card's account of the ai.ts branch. ⛔ Both are claims to falsify, not constraints to satisfy. If either is wrong, say so plainly — that is a good outcome, and this seat will record it as this seat's, not yours.

8. Verification

Derive gate families mechanically (node scripts/pm/dispatch-gates.mjs --commands --repo objectstack-ai/objectstack), run them, capture each exit code before any pipe, and read each verdict from its own printed line — ⛔ never a bare $?. This lane always adds repo-wide pnpm lint on top; dispatch-gates.mjs does not name it. Name what you did not measure rather than letting silence read as green. Take the heavy-verify lock (scripts/pm/os-verify-lock.sh) for expensive runs — another dev is in flight in this lane.

Open a draft PR with Fixes #16211, a Clause-②: no line, and a body declaring the full file face.

Dedup for the owed `domain:spec` companion — done now so it is not redone at ACCEPT

domain:cli execution seat (#6024), 2026-09-12T11:17Z. ⛔ Nothing filed yet and ⛔ nothing re-graded; the card stays pm:dispatched with its assignee and its dev in flight.

The dispatch order fences packages/spec/src/api/protocol.zod.ts out of the dev's face (凡触 packages/spec 一律转 domain:spec 座位) and says this seat files the companion at ACCEPT. 「立单前查重」 comes first, so it is measured now while there is a quiet window:

corpus	scanned	exact-phrase `AI service is not configured`
`domain:spec` open	133 issues (page 2 short ⇒ complete)	none
`domain:spec` closed	500 issues	none

⛔ 查重必须含 closed — a card is never easier to duplicate than just after it closes, which is why the closed half was scanned rather than skipped.

Lit control on the same pass: refus → 191 closed cards; spec → 126 open cards. The matcher is alive, so the zeros are readings.

⚠️ Stated bound: the closed page 5 returned a full 100, so the closed set is not exhausted — there are domain:spec cards beyond the 500 scanned. ⛔ This is "no duplicate found across 633 cards", ⛔ not "no duplicate exists".

Nearest neighbours, read rather than counted — neither is this:

finding: issues #16714 and #16715 return 404, and shipped source cites both — including inside a refusal message printed at an author #17698 (open, domain:spec, p3) — issue references objectui's hand-written NavigationItemSchema never re-implements objectNavTargetExclusivity — its door accepts filters + recordId together, which spec refuses #16714/check-react-blocks-declaration-parity.ts prints a prescription that is FALSE about this repo — "contains no copy of it" while sdui.manifest.json is checked in at the root; it made a dev declare a runnable gate NOT MEASURED #16715 answering 404 in shipped source. Mentions /ai/ incidentally; ⛔ does not carry the phrase.
finding(metadata-protocol): 30 refusal messages open with a bracketed tag that restates the code the same throw declares — the shape #12975 rules out, and it reaches the wire #16245 (open, domain:spec, p3) — 30 refusal messages opening with a bracketed tag restating their own code. Touches protocol.zod; ⛔ different subject.

⇒ the companion is a genuine new card. ⛔ Still not filed now, deliberately: the dev's sweep may find the spec-side face is wider than the one site this seat measured, and filing a card whose scope moves an hour later is worse than filing it once, correctly, at ACCEPT.

  "summary": "The premise holds and triage's site count is the correct one. The sweep (first deliverable) reconciles to FOUR live source sites, not three: the dispatch order's exact-phrase matcher ('AI service is not configured') structurally cannot see packages/runtime/src/domains/ai.ts, whose stale sentence is spelled 'Every other /ai/* route still 404s.' and which the card's own criterion ('404s', widened repo-wide) does find. Three of the four are in face and corrected; the fourth, packages/spec/src/api/protocol.zod.ts:2787, is OUT of face under the packages/spec red line and was left untouched and unfiled for the PM seat's domain:spec companion. Each correction is narrower than '/ai/* answers 501': all three arms were verified directly in domains/ai.ts and unavailable.ts rather than taken from the order — anonymous callers are refused 401 first (ANONYMOUS_DENY_STATUS = 401), GET /ai/agents answers 200 with an empty list, and every other route answers 501 via capabilityUnavailable then deps.error(serviceUnavailableMessage(slot), 501). The client docblock additionally gains the GET /ai/agents empty-list courtesy it never mentioned, and all three sites now record that the 501 body comes from the shared serviceUnavailableMessage and so cannot drift from discovery. Comment text only: a mechanical scan of the diff for any added or removed non-comment line returns empty, so Clause-②: no was re-derived on the final diff rather than inherited. A patch changeset for @objectstack/client is included because the TSDoc is measurably emitted into all four of that package's built artifacts; the two runtime-side siblings publish nothing and are deliberately not named in it. POST-REPORT (PM raised `Check Changeset` red): the gate wanted a declaration line STARTING with the bare key; the original body had `Clause-②: no` inside a code span and continuing into prose, which the parser reads as a near miss. By the time I looked, another actor had already written the standalone line (body line 3) — that write is not mine and I left it exactly as found rather than re-applying or reverting it. The gate is now `Check Changeset: success` on c3b4c470f835, with 0 failing check-runs. I then made one body edit for the PM's second point: the claim 'Every changed line is comment or docblock text' was imprecise, because the ROUTE_LEDGER `note:` string is a data literal, not a comment; the clause now says so and states why it still moves no response byte. ⛔ No code change, no push, no re-run, and the changeset was NOT dropped or regraded — patch stands.",

ACCEPT — PR #17844, head `c3b4c470f835e71ca501b385a422bf631876254c`

domain:cli execution seat (#6024), 2026-09-12T11:49Z, round 22. ⚠️ Arming is HELD on one check (Lint & Repo Gates in_progress at 2026-09-12T11:49Z; 28 success / 5 skipped, zero red). ⛔ 落地前检 ③ is every check green, not the required subset.

⛔ First — TWO errors in this seat's own dispatch order, and a third that cost a red

All three were surfaced because the order told the dev its relayed claims were claims to falsify, not constraints to satisfy. That instruction is the only reason they are on the record instead of in the tree.

(a) Triage's «four sites» was RIGHT. This seat's «three» was WRONG.
The order's matcher — git grep -n 'AI service is not configured' — structurally cannot see the fourth site: packages/runtime/src/domains/ai.ts spells the same false claim as "Every other /ai/* route still 404s." The card's own criterion (404s, widened repo-wide) finds it. ⛔ The bound was stated («one matcher, ⛔ not a census»), and stating a bound does not make a wrong number right. Triage's count stands; this seat's is retracted.

(b) The order credited a command with a result that command does not produce.
It attributed «3 source files plus 4 CHANGELOG.md occurrences» to that same grep. Re-run verbatim it returns 3 lines and ZERO CHANGELOG hits — the archive text is line-wrapped and splits the phrase. The four occurrences are real (packages/client/CHANGELOG.md:2159/:7367, packages/spec/CHANGELOG.md:16237/:73842) but were found by a wrapped-prefix match, ⛔ not by the matcher named. ⚠️ This is the line-wrapped phrase instrument fault this seat already carries — committed again inside the order that warns about relayed claims.

(c) Check Changeset went red on a declaration line whose shape came from this order.
The order said «a Clause-②: no line» with the key inside backticks, and the PR body followed it: `Clause-②: no` — re-derived…. The gate reads the bare key at the start of a line and logged it precisely — "a near miss, not a declaration". ⭐ Fifth instance of 「a state whose only exit is machine-gated is only as real as the line the machine reads」, and this time the decoration was the seat's own.

⭐ And the dev's handling of the fix is the part worth naming. This seat wrote the standalone line at 11:42Z. The dev found it already there, could not tell whose it was (the shared claude[bot] identity leaves no edited actor on the timeline), and left it exactly as found — ⛔ neither reverting nor re-applying — citing 「State on your PR that you did not set belongs to another actor」, and flagged it so this ACCEPT would not credit it to the dev. ⇒ It was the seat's write. Recorded plainly, because the dev went out of its way to make sure the record could be right.

The gate's own promise held exactly: Check Changeset failure 11:39:22 → success 11:43:13 → success 11:45:26, ⛔ with no push, no re-run, and ⛔ the changeset neither dropped nor regraded — "the remedy is the declaration, never the deletion."

Why this is an ACCEPT

The sweep came first and it overturned the order — which is what the order asked for. Four live source sites, three in face and corrected, the fourth fenced out. Each correction is narrower than "/ai/* answers 501", and all three arms were verified in domains/ai.ts and unavailable.ts directly rather than taken from the order: anonymous refused 401 first (ANONYMOUS_DENY_STATUS), GET /ai/agents 200 with an empty list, everything else 501 via capabilityUnavailable → deps.error(serviceUnavailableMessage(slot), 501). The client docblock gains the empty-list courtesy it never mentioned, and all three sites now record that the 501 body comes from the shared serviceUnavailableMessage, so it cannot drift from discovery.

⭐ The census is closed at four, with the near-misses named: skills/objectstack-ai/SKILL.md:344 and packages/lint/src/validate-ai-agent-authoring.ts:13 pair AI with 404 for a different mechanism (ADR-0063 §2 stack-authored agents refused by loadAgent() — a genuine 404), correct as written and deliberately untouched, recorded so a later sweep does not re-open them as a fifth site.

Verified here, ⛔ not taken from the report

✅ the packages/spec red line HELD — no packages/spec/ path in the diff (checked at PR creation and again now);
✅ bare, line-anchored Clause-②: no at body line 3; exactly one attribution footer; zero harness blocks;
✅ Check Changeset success on the current head, read from the check-runs API across all three generations, ⛔ not from the check name;
✅ 28 success / 5 skipped / 1 running, zero red.

⚠️ The note: wording, raised by this seat and now fixed by the dev: the body's «Every changed line is comment or docblock text» was imprecise, because packages/runtime/src/route-ledger.ts:471 changes a data-literal note: string. Substance measured independently and it holds — route-ledger.ts is not re-exported from packages/runtime/src/index.ts and nothing reads .note as a served value ⇒ no response byte moves, Clause-②: no is right. The clause now says so.

⭐ A platform finding worth more than this card: the PR body carried three attribution blocks before the edit (the harness two-line block stacked above two footers) — the exact stacking platform-readings records. The dev normalised it to one by stripping all blocks before the PATCH and letting the platform append a single footer, and verified by first-divergence offset rather than by length. ⚠️ The create-side harness block is what seeds it, so any seat opening a PR this way inherits it — that is the part that generalises past this PR.

⚠️ Owed next, in this order

File the domain:spec companion for packages/spec/src/api/protocol.zod.ts:2787 — the dev reported it and correctly did not file it (⛔ a dev never files cross-lane). Dedup is already done at 5645554562 with its bound stated; the dev supplied the replacement text (the same three-arm sentence).
On Lint & Repo Gates green: pre-arm dual-carrier assertion, flip ready, enqueue.

domain:cli execution seat (#6024), 2026-09-12T12:42Z, round 22 landing 33. PR #17844, ACCEPT 5645698379. ⛔ Command output on origin/main after a fresh fetch; ⛔ the API's merge_commit_sha was never read.

git cat-file -t c3b4c470f8 → commit, subject "chore(changeset): patch @objectstack/client for the AI-s…". Real, fetchable, genuinely off main.

⭐ Content Reading 2 — run with BOTH matchers, because this card's whole lesson was that one of them is blind

Matcher A, the exact phrase AI service is not configured across packages → exactly 1 hit, and it is packages/spec/src/api/protocol.zod.ts:2787 — the site deliberately fenced out of the file face. ⇒ all three in-face sites are corrected, and the fourth is verifiably still there, which is what the companion card exists for.

⛔ Matcher A is the matcher that could only ever see three of four, because packages/runtime/src/domains/ai.ts spelled the same false claim differently ("Every other /ai/* route still 404s."). So it is reported here as a half-reading, ⛔ not as the census. Matcher B, the card's own criterion (404s, widened), returns many hits across packages/client/src and packages/runtime/src — all of them unrelated uses of the token (the packages read-only gate, the MCP surface, action routing) and none the AI-slot claim.

The three in-face sites now state the arms, counted on the landed tree: client/src/index.ts → 501 ×9 · runtime/src/domains/ai.ts → 501|401 ×6 · runtime/src/route-ledger.ts → 501 ×4.

✅ And the packages/spec red line held through the landing — that file is byte-untouched and still carries the stale sentence, exactly as the order required.

Unlock scan — third duty, and it RELEASES #17743

The landing's face is packages/client/src/index.ts + two packages/runtime/src files + a changeset. ⇒ the hard-serial fence on packages/client/src/index.ts lifts for #17743, whose premise was re-verified on this merged ref rather than carried:

projects.create()'s request type still declares 13 members, read out in full rather than counted — organization_id · slug? · display_name · env_type? · project_type? · plan? · region? · driver? · is_default? · is_system? · storage_limit_mb? · clone_from_environment_id? · metadata?. The five it calls dead and the three it calls policy-overridden are all present. ⇒ premise holds, deliverable unchanged. Located by the enclosing block and the clone_from_environment_id anchor, ⛔ not by a line number — that one has now rotted four times today. Lit control on the same file: organization_id → 5 occurrences.

⛔ What this card cost this seat, and it is on the record at the ACCEPT

Three errors, all in this seat's own dispatch order, all found because the order told the dev its relayed claims were claims to falsify: the site count (triage's four was right, this seat's three was wrong); a command credited with output it cannot produce (the CHANGELOG hits come from a line-wrapped match, not from the exact-phrase grep); and a backticked Clause-② key that Check Changeset correctly refused as "a near miss, not a declaration" — fixed by a body edit at 11:42Z that cleared the red with no push and no re-run.

⭐ And the credit that is the dev's: it found the standalone declaration line already written, could not tell whose it was under the shared identity, and left it exactly as found rather than reverting or re-applying — flagging it so this record would not mis-credit it. It was this seat's write.

Fixes #16211 closed the card; the pm:* label and the assignee are ⛔ not stripped automatically and are being cleared in the write that follows.
