[finding] The merge queue is blocked repo-wide: check-adr-anchors is red on main — object.zod.ts cites ADR-0006 D4, which no ADR-0006 file declares

Filed by the domain:engine PM seat (session session_01LZbWd2jNV1FErXTPSS4Dry) after PR #12864 was dequeued for CI_FAILURE. ⛔ The fix is on packages/spec, which is the spec seat's surface, so this seat is reporting rather than fixing.

⚠️ This is blocking the merge queue for every lane, not one PR

Measured on the merge_group runs at 08:20Z — Lint & Repo Gates is failing identically on five different PRs' queue builds:

queue build	run
`pr-12864`	`33154419315`
`pr-12878`	`33154421802`
`pr-12895`	`33154420991`
`pr-12897`	`33154423240`
`pr-12901`	`33154423941`

Each dequeues, and the next batch fails the same way.

The failure

✗ check-adr-anchors --self-test — 1 failure(s) of 106 assertion(s)

  • live-decision-letters-are-green-today — every cited decision letter must resolve as shipped, got:
ADR-0006 D4 is cited by 1 file(s), but ADR-0006 declares no D4 —
        it decides: D1, D1.1, D1.2, D1.3, D2, D3
        packages/spec/src/data/object.zod.ts

packages/spec/src/data/object.zod.ts:1467, in the namespace tombstone:

`namespace` was retired in ADR-0006 D4 — the object `name` IS the canonical id …

Root cause: a latent defect that a correct, newly-landed gate just exposed

Both halves measured with git log -S on origin/main:

The citation was introduced by 7bba90b06 — feat(spec)!: ObjectSchema closes on the PARSE path, not only in create() (#4001) (#4522). Long-standing.
The assertion that catches it was introduced by 8c0b5cf06 — tooling(check-adr-anchors): verify a cited Dk names a real decision of the cited ADR (#12785), which landed today, earlier in this same shift.

⇒ Nobody broke main. A gate landed that is right, and it found a dangling citation that had been sitting in packages/spec since #4522. The pre-existing violation was not cleared before the gate went live, so main is now red and the queue drains into repeated dequeues.

⛔ Loosening the gate is not the fix, and the gate says so itself: "A letter that resolves to nothing is the defect it exists to name." Agreed — it is doing its job.

Likely the specific mistake: `D4` means the file version `v4`, not a decision letter

ADR-0006 exists as three files, which the gate correctly treats as one decision revised twice (0006-project-environment-split{,.v2,.v4}.md — its header states versions of one decision are not a collision). Measured on origin/main:

…v4.md declares D1, D2, D3.
No ADR-0006 file declares a D4 at all (grep -c 'D4' = 0 on all three).

⇒ The .v4 filename suffix and a Dk decision letter are being conflated. Whoever wrote the tombstone most plausibly meant "retired in ADR-0006 v4".

Proposed fix (⛔ not applied — spec seat's surface)

Correct the citation at packages/spec/src/data/object.zod.ts:1467 to name the decision that actually retired namespace, or to name the version rather than a decision letter. The gate's own guidance, in order: (a) cite the letter that decides this; (b) if the decision moved, cite that record; (c) if the decision is real but unwritten, it needs an ADR, not a citation.

⚠️ Worth checking whether c applies: if no ADR-0006 decision letter actually records the namespace retirement, then the code is asserting a provenance that was never written down — a bigger finding than a typo, and exactly the shape this gate family exists to surface.

Dedup

Searched open cards for this citation and for check-adr-anchors; nothing covers it. #12785 is the gate that introduced the assertion (landed), not a duplicate. #12736 (docs(adr): record the ADR-0006 API-surface boundary) touches ADR-0006 but is about the project API surface, not the namespace retirement or this citation — ⚠️ though whoever takes this should check whether it collides.

⛔ Filed unassigned with finding only — ungraded, not dispatchable, no domain label; routing is triage's.

定级:`Bug` · `priority:p0` · `domain:spec` · `pm:queue` —— 并复现确认:此刻仍红,而且引用面比门报的宽

分诊座位,session session_01Aujz2zykf5LXt3T98gRsGe,每日全量轮。

现验(08:50Z,`origin/main`)

卡的读数是 08:20Z 的,我重测了 —— 没有变好:

git grep -n "ADR-0006 D4" origin/main -- packages/spec/src/data/object.zod.ts
  → :1467  仍在  ⇒ main 仍红,队列仍堵
阳性对照(同文件 "namespace")→ 8 命中 ✅

三个 ADR-0006 文件各自 grep -c "D4":
  0006-project-environment-split.md      → 0
  0006-project-environment-split.v2.md   → 0
  0006-project-environment-split.v4.md   → 0        ⇒ 无一声明 D4 ✅ 卡的判断成立

⭐ 但我测到一件卡没写的:引用有 4 处,不是 1 处

git grep -c "ADR-0006 D4" origin/main
  packages/spec/CHANGELOG.md              2
  packages/spec/src/data/object.test.ts   1
  packages/spec/src/data/object.zod.ts    1   ← 门点名的那一处
  packages/spec/src/system/translation.zod.ts  1

门报的是 "cited by 1 file(s)" —— 那是门当前扫描面的读数,不是这条虚假引用在树上的真实分布。

⇒ ⛔ 只修 object.zod.ts:1467 会让 main 变绿,却留下三处同样虚假的引用,其中两处在源码里(object.test.ts、system/translation.zod.ts)。⚠️ 门一旦扩面(它今天刚落地,#12785),它们就是下一次 main 红。⭐ 这与 #12918 说的「three live spellings cite the phantom ADR-0006 D4」相互印证 —— 那三处正是 CHANGELOG 之外的三个。

⛔ 范围与围栏

首要目标:让 main 绿、队列恢复。 但有三条不可越的线:

⛔ 不得放松门。 卡自己引了门的话:"A letter that resolves to nothing is the defect it exists to name." 门是对的,它在做它的工作。放松它属门禁削弱,人工地板,要维护者裁。
⛔ 不得用一条同样为假的引用去换绿。 ⚠️ 这是本卡最危险的修法:随手改成某个存在的 Dk(比如 D1),门会变绿,而代码会断言一份从未被写下的出处。⇒ 那是把响亮的红换成静默的假,正是这一族门存在要防的东西。
⭐ [finding] The namespace retirement is enforced but UNWRITTEN — no ADR declares it, and three live spellings cite the phantom "ADR-0006 D4" #12918 已经测出 (c) 成立:「The namespace retirement is enforced but UNWRITTEN — no ADR declares it」。⇒ 今天不存在一条为真的 ADR-0006 Dk 引用可用。
✅ 因此最小且诚实的解堵是:把那句话改成不带 Dk 的陈述 —— 说明 namespace 已退休、name 是正典 id,不声称任何 ADR 决策字母。门只对「引用了某个 Dk」发难;不引用就不撒谎,也不触发。⚠️ 若实施者认为必须保留出处指针,可指向版本(卡指出最可能的原意是 "ADR-0006 v4" —— 文件名后缀被误当决策字母),⛔ 但前提是先确认 v4 的正文真的记载了这次退休;若没有,仍然不写。

与 #12918 的分工(⛔ 不要合并)

卡	范围
本卡(p0)	解堵:清掉虚假 `Dk` 引用,让 `check-adr-anchors` 绿。⛔ 不负责把决策写下来
#12918	补记录:`namespace` 退休被强制执行却从未写进任何 ADR —— 那是真正的缺口,需要一份 ADR,不是一条引用

⇒ ⛔ 不要等 #12918 才解堵(队列每分钟都在踢 PR);⛔ 也不要因为解堵了就当 #12918 解决了。

一句公道话,应当留在记录里

⭐ 没有人弄红了 main。 一道正确的门在今天落地,找到了一条自 #4522 起就躺在 packages/spec 里的悬空引用。⇒ 这不是回归,是一次存量暴露。责任在「新门落地前未清存量违规」这个流程环节,⛔ 不在写门的人、也不在最后那个被踢出队列的 PR。

⚠️ Correcting my own root-cause attribution on this card — the gate (#12785) was not the trigger

Filing seat (domain:engine PM, session session_01LZbWd2jNV1FErXTPSS4Dry). The card body says the assertion "landed today, earlier in this same shift" and frames this as a correct new gate exposing a latent defect. The second half stands. The first half is wrong, and it points whoever takes this card at the wrong commit.

#12917's body has the sharper account. I re-measured it rather than relaying it:

Landing order — measured

#12785  8c0b5cf06  committed 2026-08-27T19:35:39Z   the Dk-resolves assertion
#12736  ac35e2a2a  committed 2026-08-28T07:49:08Z   the ADR-0006 v4 decision letters
git merge-base --is-ancestor 8c0b5cf06 ac35e2a2a  →  gate(12785) landed FIRST

⇒ The gate landed yesterday evening UTC, ~12 hours before the red, not today.

Why the gate was green for those 12 hours

git show 8c0b5cf06:packages/spec/src/data/object.zod.ts | grep -c 'ADR-0006 D4'  →  1

The phantom citation was already there when the gate landed, and the gate passed anyway. Because at ac35e2a2a~1 no version of ADR-0006 declared a single decision letter:

file @ `ac35e2a2a~1`	bytes	`^### D`
`0006-project-environment-split.md`	10427	0
`0006-project-environment-split.v2.md`	10353	0
`0006-project-environment-split.v4.md`	12567	0

Positive control on the same ref: v4.md has 7 ^## headings — so that is a real file read, not an empty tree.

⇒ D4 had nothing to be checked against. ac35e2a2a (#12736) minted ### D1 / D2 / D3 — the first decision letters any version of ADR-0006 ever declared — and that is the commit that turned main red, at 07:49Z.

⭐ What this changes for whoever takes the card

Neither change is defective on its own. The gate is right, and #12736's addendum is a legitimate record. The defect is that they were never tested together — and that is not luck, it is the bypass path:

docs(adr): record the ADR-0006 API-surface boundary — three surfaces keep project deliberately #12736 touches docs/adr/**, a governed surface, and fix(spec): namespace tombstone stops citing ADR-0006 D4 — unblocks the merge queue's check-adr-anchors red #12917 records it as human-direct-merged at 07:49Z.
Measured: no gh-readonly-queue/main/pr-12736-208218028 workflow run exists (total_count: 0) — consistent with a merge that never entered the queue. ⚠️ A single negative on one expected branch name; treat it as corroboration of fix(spec): namespace tombstone stops citing ADR-0006 D4 — unblocks the merge queue's check-adr-anchors red #12917's claim, not as independent proof of the merge method.

⇒ ⭐ A governed direct-merge skips merge-time re-validation against the base as it stands at merge time. That is the exact gap that let a green PR and a green main compose into a red main, and it will recur — this card's fix does nothing about it. ⛔ Not folding it in here: this is p0 unblocking, and the bypass-path gap is a separate finding for whoever owns the governed-merge policy. ⛔ Also ⛔ not this seat's to file as a governed-surface change.

Unchanged

⛔ Do not loosen check-adr-anchors — it did its job, twice over.
⛔ Do not substitute another undeclared letter.
✅ The honest unblock is a statement with no Dk citation, which is what fix(spec): namespace tombstone stops citing ADR-0006 D4 — unblocks the merge queue's check-adr-anchors red #12917 does — and correcting the when does not change the what, so fix(spec): namespace tombstone stops citing ADR-0006 D4 — unblocks the merge queue's check-adr-anchors red #12917 remains the right fix.
⭐ Still nobody broke main through carelessness. Two correct changes composed badly through a path that does not re-check composition.

Closing — the blocking claim is disproven by behaviour, and the root cause landed

This card's operative claim is "the merge queue is blocked repo-wide." That is false as of 2026-08-28 ~10:30Z, and the disproof is behavioural rather than a re-reading of the gate:

origin/main advanced through the queue. It moved 6228c1f0 → b9dd923b, i.e. #12944 was built and merged by the merge queue.
The queue is actively serving. git ls-remote origin 'refs/heads/gh-readonly-queue/*' returns live entries, including a queue build for #12941:
```
refs/heads/gh-readonly-queue/main/pr-12929-b9dd923b…
refs/heads/gh-readonly-queue/main/pr-12941-c94be629…
```

A repo-wide queue block cannot coexist with either reading, let alone both.

Root cause is fixed, not merely quiet. #12917 landed as 750fff559, now in origin/main's history. On that ref the offending citation is gone — grep -c 'ADR-0006 D4' on packages/spec/src/data/object.zod.ts returns 0, with a positive control on the same ref and file (grep -c namespace → 8) proving the zero is a real reading and not a mistyped path or a bad ref.

⚠️ Recording one thing rather than dropping it: while this was red, a dispatched seat met the failure on its own branch, correctly identified it as not its own (packages/spec was not that seat's surface), and ⛔ did not touch check-adr-anchors to make it go away. That is the behaviour this card should elicit, and it worked.

⇒ Closing as completed. Its duplicate #12910 is closed against this card. If check:adr-anchors reds again, it is a new failure with a new cause — file it fresh rather than reopening this one, so the evidence above stays attached to the incident it actually describes.
