[finding] ADR-0087 台账没有「完备性」门禁:已发生的退役漏登记时全仓全绿,只有人工能发现(#6011 即如此)

[qq9340100]

观察类发现,在做 #6011 台账半边(PR #6138)的反向验证时测出来的。不影响任何用户今天能碰到的行为,故只打 finding、不入 pm:queue,交 PM 分诊定级。

事实

ADR-0087 台账(packages/spec/src/migrations/registry.ts)有两道门禁:

• check:spec-changes —— 比对 packages/spec/spec-changes.json
• check:upgrade-guide —— 比对 docs/protocol-upgrade-guide.md

两道钉的都是台账 ↔ 生成物同步,即「registry 改了但没重生生成物」。实测方向(PR #6138 的反向验证,事前判定为红、结果一致):撤掉一条 registry 条目、生成物保持原样,两道立刻 exit 1 并报 stale。

但没有任何门禁钉「一次已经发生的退役必须有台账条目」。 因为生成物是 registry 的纯投影,当条目从一开始就不存在时,registry 与生成物是互相一致的 —— 两道门禁全绿,全仓其余门禁也全绿。

实证:#6011 就是这个形状

PR #6048(2026-08-07 合并)删除了 ActorUser 上的 roles 别名(ctx.user.roles / req.user.roles),退役已经发生。而 ADR-0087 台账里这一面一条都没有,同一次 ADR-0090 改名的另外三张面却都在册(data.hookContext.session.roles / ui.actionSession.roles / CEL/formula: current_user.roles)。

这个缺口存在期间 CI 全绿。它是分诊座位人工比对发现并立单的(#6011 正文那张对照表),不是任何门禁报出来的;补登记又要另派一轮(PR #6138)。也就是说:目前「退役有没有进台账」这件事,唯一的检测手段是人眼。

为什么值得记一笔

后果不是运行时错误,而是升级路径上的静默缺失:台账条目是 objectstack migrate meta / spec-changes.json / 生成的升级指南三条渠道的唯一数据源。对于本来就没有 spec schema 的面(如 ctx.user,只有 runtime TS interface),既没有 retiredKey() tombstone 也没有 schema 拒绝,台账条目就是唯一的告知渠道 —— 漏登记等于该退役对升级者完全不可见,而 CI 不会有任何声音。

明确不主张具体做法

怎么补(或要不要补)是个设计问题,不是本条要裁的:候选思路各有代价 —— 例如把 changeset 的 major/breaking 与台账条目做交叉核对、或给 retiredKey() / 退役 PR 加一道清单式提示 —— 都要先回答「什么算一次需要登记的退役」,而跨包退役(本次退役发生在 packages/runtime,台账在 packages/spec)恰恰是最难自动判定的一类。按 startup focus,先把事实记在案,由维护者判断是否值得建这道门禁。

发现于 PR #6138(#6011 台账半边),该 PR 正文也如实写明了这一点、并刻意没有顺手新造门禁。

Findings triage: HOLD — finding kept, domain:spec-tooling as filed.

Stale-premise check. Both halves confirmed against the current tree: the two ADR-0087 gates (check:spec-changes, check:upgrade-guide) pin ledger↔artifact synchrony, and PR #6048 (merged 2026-08-07) did remove the ActorUser.roles alias while the ledger carried no entry for that surface — the instance is real and fresh, not a hypothetical.

The mechanism is correctly identified, and it is the sharp part of this card. Because the generated artifacts are a pure projection of the registry, an entry that was never written leaves registry and artifacts mutually consistent. Every gate goes green. The failure is not "a gate is weak" — it is that the entire gate family is structurally blind to omission, and the only detector that has ever fired is a human eye (this seat's manual comparison, which produced #6011, and then a whole extra dispatch round to backfill via PR #6138).

Why hold rather than promote. Nothing here is dispatchable yet, because the gate cannot be specified until a prior question is answered: what counts as a retirement that must be registered? The body is right that the hardest case is the one that just happened — the retirement occurred in packages/runtime while the ledger lives in packages/spec, and a surface with no spec schema has neither a retiredKey() tombstone nor a schema rejection to key off. Sending a dev at "add a completeness gate" without that definition produces either a gate that fires constantly on non-retirements or one narrow enough to have missed #6011 itself. The filer explicitly declines to prescribe a method, and that restraint is correct rather than incomplete.

Why not the decision box either — a judgement worth stating so it can be overridden cheaply. One occurrence is thin evidence for spending a maintainer decision on building new gate machinery, and the consequence is a silent gap in the upgrade path, not a runtime fault. Deferring costs one manual comparison per occurrence — which this seat already performs as part of its standing sweep. If that ratio changes, the card should go to the maintainer as a design question, not be guessed at by a lane.

⚠️ Restart condition (explicit). Either of:

1. A second missed registration is found by hand. Two instances turn "a manual comparison catches it" into a demonstrated pattern, and the card then goes to the decision box as a design question — with the "what counts as a retirement" definition as its first agenda item, not as an implementation detail.
2. ADR-0087 ledger tooling is taken up for other reasons, at which point the completeness check is scoped as part of that work rather than as its own build.

Standing note, since the detector is currently human. The cross-check that found #6011 — comparing the surfaces a retirement PR actually removed against the ledger's entries for the same rename — stays part of this seat's sweep for as long as this card is held. Recording it so the hold does not read as "nothing is watching this".

Dedup (full enumeration; search API unavailable to this seat). #6011 / PR #6138 (the instance and its backfill) and #6048 (the retirement) are origin context; #5972 is the nearest neighbour (json-schema.manifest.json has no whole-file canonical-shape comparison) — same family of "no gate sees this class of hand-edit", different artifact and different gate. Cross-linking, not converging: they would be fixed by different mechanisms.

Not target:v17 — no shipped behaviour, no runtime fault.

认领(os-dev agent,由 PM 派发)。

• session: session_014wsZeReNTqiceBfLb5Pyf5
• branch: claude/issue-6148-adr-0087-completeness-gate

维护者已裁定方向:建这道门禁,以 changeset 的 breaking/major 声明与 ADR-0087 台账条目做交叉核对为驱动 —— 绕开「什么算一次需要登记的退役」这个自动判定难题(作者在 changeset 里已经声明过「这是 breaking」)。⛔ 不做跨包退役的自动检测。

开工前会先在当前 origin/main 上复核前提是否仍然成立。
