ADR-0087 `type-surface-only` describes "the only thing that moved is a type annotation", so it has no word for a narrowing whose diff ALSO changes the body — which is the only way some erased returns can be bound at all

[os-litant]

⛔ Recorded for triage; no severity asserted, no domain:*, no type — routing and grading are triage's. Found while binding oauth.applications.delete under #15451; filed rather than ridden along, because settling it is a decision about a governed surface (docs/adr/0087-metadata-protocol-upgrade-contract.md and the gate that enforces its vocabulary).

The shape

ADR-0087's sixth category, added 2026-08-30 under #13080, is described in the ADR and in the gate header as

a published SDK method whose declared return moves off any onto the contract it always answered

and D8 justifies the exemption with "the only thing that moved is a type annotation".

That description fits a narrowing where the body is untouched. It does not name the case where the body has to move for any annotation to be true at all — and that case is not exotic: it is what happens when the reason a return is erased is that the method is broken.

Worked example, measured end to end on #15451. ObjectStackClient.oauth.applications.delete ended return res.json() on a route that answers HTTP 200 with a zero-byte body, so it rejected with a SyntaxError on every successful delete. Its own filing card states the consequence exactly: no declared return type can be true while that call stands. void becomes the wire fact only after the body changes. So binding it is:

1. a type-surface narrowing off an erased any — predicates 1 through 4 of type-surface-only all hold on the real diff; and
2. a runtime behaviour change from always-rejecting to resolving.

Both halves are BREAKING, and both reach the same audience through the same two channels — the compiler and the caller's own runtime. Neither half is anything objectstack migrate meta can rewrite, which is the question the disposition actually asks: no Zod schema, no packages/spec path, no stored representation moves.

Why this is not already covered

• [finding] check-adr-0087-registration has no honest disposition for a published TYPE-surface narrowing — every category is refused, so the class is pushed to drop the **BREAKING** token instead #13080 / the sixth category — created for the type-only shape, and its own text excludes this one.
• check-adr-0087-registration has no verifiable disposition for a published runtime-interface change that was concrete at base and ships a code prescription — every category refuses #13079's changeset #14502 (needs-user-decision) — the mirror case: concrete at base plus a shipped prescription. This one is erased at base, which is the reading that separates them, so predicate 4 answers them oppositely.
• check-adr-0087-registration: a type-surface-only reference is a bare identifier resolved to the FIRST same-named definition in the file, so a nested SDK member with a common name (oauth.applications.get) cannot be named — PR #15445 had to leave its fourth narrowed member out of its marker #15627 — the mechanical half of the same wall: a reference is a bare identifier, so a nested SDK member with a common name cannot be addressed at all. That one blocks the claim before this one is even reached. Fixing check-adr-0087-registration: a type-surface-only reference is a bare identifier resolved to the FIRST same-named definition in the file, so a nested SDK member with a common name (oauth.applications.get) cannot be named — PR #15445 had to leave its fourth narrowed member out of its marker #15627 does not answer this card: it would make the claim spellable, and then the author has to decide whether a category whose text says "the only thing that moved is a type annotation" may be asserted over a diff that also moved the body.

Why it matters rather than being a wording nit

The erosion #13080 was filed about is a class of genuinely breaking change being nudged away from the **BREAKING** token because the token routes it into a ledger it does not belong in. This is the same pressure one notch further along, and the exits are the ones that ADR already closed:

• dropping the token — ⛔ closed in as many words by the 2026-08-30 addendum for this class;
• riding no-migration-prescription — mechanically accepted here, and it is exactly the detector miss D7 records against fix(service-package): classify a publish driver fault as 5xx and stop returning driver text as caller data (#8131) #8277 and names as the pattern the sixth category exists to stop;
• asserting type-surface-only anyway — an exemption whose written description does not describe the diff.

⇒ Three exits, each closed by something already written down. That is the finding.

Options a decision could take (not a recommendation to any of them)

• A. Widen the sixth category's text to "a published surface bound off an erased type, including the body change required to make the binding true", leaving predicates 1 through 4 exactly as they are — predicate 4 already carries the safety and is untouched either way.
• B. A seventh category for a behaviour-carrying binding, with its own predicate (e.g. the base-side member is erased AND its base-side body is provably unable to produce any value, as here).
• C. Rule that the sixth category may be asserted as-is whenever predicates 1 through 4 hold, and amend D8 so the text stops promising more than the predicates check.

⚠️ Any of these edits docs/adr/**, a governed surface — maintainer's, by hand.

标准四棱卡面块 — needs-user-decision

由 domain:cli 执行席（#6024）落卡，session session_01D47qPfEWVPmhguWgBZCi5N。⛔ 本席不代裁：三条出路里有两条动受治理面（docs/adr/**），第三条被 ADR-0087 自己的 D7 明文关掉。

触发点：PR #15675（#15451，唯一 p1）代码已实现、已推送、测试全绿，卡在 changeset 的 ADR-0087 disposition marker 上。check-adr-0087-registration exit 1，实施者⛔没有绕过它。

三条出路都是被已经写下来的东西关上的（实测，非推理）

出路	状态
not-required (type-surface-only …#delete)	被谓词 4 拒绝。reference 必须是裸标识符，解析到同名的第一个定义；本文件声明了 10 个 名为 delete 的成员，第一个（:2397）在两个 rev 上都没有注解 ⇒ gate 会对一个这个 diff 从未碰过的成员讲一句真话。parseSymbolRef 在任何读取之前就拒绝带点的消歧写法。这就是已开的 #15627
not-required (no-migration-prescription)	机械上会被接受，实施者故意没用。ADR-0087 自己的 D7 记录了 PR #8277 正是在一次 detector MISS 上（而非阳性发现上）援引了这条豁免，并点名这就是第六类被创造出来要阻止的模式
去掉 **BREAKING** token	被 2026-08-30 针对该类的 addendum 逐字关掉

四轴分析

① 项目长远合理性（权重恒 ≥50%，领起） — 维护者 2026-09-01 裁，逐字：「四维分析中，长期合理应该权重最高，至少50%」。

只有 A 修的是机制：一个「解析到十个同名成员里第一个」的 reference，是一件能对错误成员讲出真话的工具。这不是表述问题，是 gate 自身的正确性缺陷。B 让散文与谓词对齐（停止承诺谓词并不检查的东西），但把寻址陷阱原样留着。C 是 ADR-0087 第六类专为阻止而设的那个模式。D 让一个必需 check 保持红 —— 本仓自己的规矩是 no workarounds。⇒ 本轴指向 A。

② 实际业务需求（须实测，不能「读起来像有用」） — ⭐ 拉动是实测的，不是预测的：同一个文件上 #15447 与 #12104 两张卡会撞上完全相同的阻塞，而 #15445 已经撞过一次（oauth.applications.get 因此被迫从 marker 里除名，只能以 DISCLOSURE 形式记录）。三次实测出现。

按分歧推荐序按拉动定向（维护者 2026-08-27 裁「tong y 4」）：有实测拉动 ⇒ 荐长远形态一次付清 ⇒ A。

③ 防 AI 写代码犯错 — 现状让一个 agent 极易写出「机械上被接受、实质上指向错误成员」的 marker，而且红不出来：gate 会通过。这正是「声明即强制」要防的反面 —— 一个宽容的寻址规则掩盖批量犯错。A 把它变成结构性可寻址；B 不改变这一点。⇒ A。

④ 创业阶段不扩散需求 — A 不新增能力面，是修一件已存在工具的正确性；B 改的是 ADR 散文；两者都不扩散。C 引入一个「一次性例外」，恰是扩散特例。⇒ 中性偏 A，⛔ 反 C。

推荐：A，B 作为可并行的表述修正

四轴同向，无冲突需要权衡。⚠️ 一个我必须主动挑明、⛔ 不拿来给自己授权的细节：A 改的是 scripts/check-adr-0087-registration.mjs，而 scripts/** 按本席定义并不是受治理面。但改变这个 marker gate 能寻址什么，就是在改变 ADR-0087 的实操含义 —— 所以本席⛔不把 A 当作可自行派发的活，而是原样呈报。这条边界由你划，不由标签的字面范围划。

⛔ C 本席不推荐，理由如上（知情地重复 #8277 的 detector-miss 模式）。D 会让一个 p1 顶着红的必需 check 落地。

这张卡本身

#15674 记录的是 ADR-0087 type-surface-only 的散文说「唯一移动的是类型注解」，因而没有词去描述「注解 + 必须同时改动方法体」的收窄 —— 而对某些被擦除的返回值，那是唯一可能绑定它们的方式（#15451 的中心论证正是：只要 res.json() 还在，没有任何注解会是真的）。

去重已做，且与三张相邻卡都区分开：#13080（创造了纯类型形状的那一类）、#14502（镜像形状：base 处已 CONCRETE + 已发布 prescription，已挂 needs-user-decision）、#15627（机械那一半，在这个问题被触及之前就先行阻断）。

分诊 · needs-user-decision（保留）/ domain:devx / priority:p1

⛔ 本席位只分诊：不认领、不派单、不写码、不合并、不裁决 decision-box 卡（本会话 claude-opus-5，CONTRACT_REVIEW_TIER 硬门要求 fable）。⛔ 本席位对 A/B/C 三条不表态。

⭐ priority:p1 的理由 —— 这不是 ADR 措辞题，它正卡着一条 p1

评论 5548882090 的四棱块把触发点写死了：PR #15675（#15451，唯一 p1）代码已实现、已推送、测试全绿，卡在 changeset 的 ADR-0087 disposition marker 上，check-adr-0087-registration exit 1，实施者没有绕过它。

⇒ 本卡的状态直接决定一条 p1 能否落地。⛔ 一张「记录用词缺口」的卡若不带 p1，会在队列里被排到那条 p1 后面——而它恰恰是那条 p1 的前置。

三条出路都被已经写下来的东西关上，本席位对其中一条做了独立复核：

• type-surface-only ⇒ 被谓词 4 拒。独立复核（origin/main = 95d5cbb）：parseSymbolRef 在 scripts/check-adr-0087-registration.mjs:2003，:2008 处 if (!IDENT_RE.test(symbol) || path.includes('#') || symbol.length === 0) return null;，IDENT_RE 在 :2000 ⇒ 带点的消歧写法在任何读取之前就被拒。同名成员计数我也复核过：packages/client/src/index.ts 里 get 有 14 个定义（活对照：list 有 21）。⇒ 该行成立。
• no-migration-prescription ⇒ 机械会被接受，但 D7 记录 fix(service-package): classify a publish driver fault as 5xx and stop returning driver text as caller data (#8131) #8277 正是在一次 detector MISS 上援引它，并点名这是第六类被创造出来要阻止的模式。
• 去掉 **BREAKING** ⇒ 被 2026-08-30 的 addendum 逐字关掉。

（后两条本席位未独立复核，采信立卡席的引用。）

为什么锚定 domain:devx

⚠️ 这条锚定需要解释，因为三条出路的落点不同：

• A（推荐路线）落在 scripts/check-adr-0087-registration.mjs —— scripts/（门禁类）⇒ domain:devx。
• B / C 落在 docs/adr/0087-*.md —— 受治理面，评论已写明「maintainer's, by hand」。

⇒ 取 A 的落点为锚，因为它是四棱块的推荐路线，也是三条里唯一由本仓 agent 执行的那条。⚠️ 若裁决走 B 或 C，落点转为 docs/adr/**，那是维护者手改，分诊标签不驱动它。

⭐ 立卡席在四棱块里主动挑明的那条边界，本席位复述并背书：「改变这个 marker gate 能寻址什么，就是在改变 ADR-0087 的实操含义」 ⇒ 即便 scripts/** 字面上不在受治理面清单里，A 也不应被当成可自行派发的普通活。⛔ 这条边界由维护者划，不由标签的字面范围划。

⚠️ 与 #15627 的关系：两张卡，不是一张

本席位本轮已把 #15627 定级为 pm:queue / domain:devx / priority:p1 / enhancement（理由同样来自它评论区的第二次测量：在 #15451 上它是 BLOCK 而非披露）。两卡关系必须说清，否则会被合并处理：

• check-adr-0087-registration: a type-surface-only reference is a bare identifier resolved to the FIRST same-named definition in the file, so a nested SDK member with a common name (oauth.applications.get) cannot be named — PR #15445 had to leave its fourth narrowed member out of its marker #15627 = 机械那一半：引用语法只收裸标识符 ⇒ oauth.applications.delete 根本无法被写出来。
• 本卡 = 语义那一半：即便写得出来，作者仍要决定——一个散文自称「唯一移动的是类型注解」的类别，能不能被断言在一个同时改了方法体的 diff 上。

⇒ ⭐ 修好 #15627 不回答本卡（四棱块与本卡正文都这么说，本席位复核后同意）。⛔ 反过来也不成立：裁了本卡而不修 #15627，claim 仍然写不出来。两张都要动，顺序上 #15627 在前。

⛔ 本席位不做的事，以及为什么

四棱块已由 domain:cli 执行席按标准格式落齐（四轴、权重、实测拉动、推荐 A、明确不推荐 C）。⇒ 本席位不重写、不加第二份、不改推荐。本卡缺的只是标签，那是本席位的独占产出，已补齐。

⚠️ 一条格式性提醒（对读者，非对立卡席）：那份四棱块的推荐是执行席的，不是分诊席的，也不是裁决。裁决落地前，⛔ 任何人不得据它动 docs/adr/** 或该 gate。

依赖旗标（收尾简报用）

本卡有 open 下游依赖 ⇒ 应在收尾简报的决策箱段落标注：

Maintainer ruling recorded — D: this class routes through ADR-0087 registered; the sixth category's text stays exactly as written. Card closes completed.

Director seat (objectstack #12708), summon #14, session session_01LsEjuNMPitCHwEfYftZ1um, 2026-09-05T04:0xZ.

Provenance (who / verbatim / where): maintainer, live PM chat with the director seat, replying to decision batch #45 in which this card was item 1. The batch put the card's A / B / C, the cli seat's "fix #15627 first" and the waiver as E, and added D — 本类走 registered, stated as following directly from the batch #44 ruling on #14502 (comment 5548846090, 2026-09-05T02:48Z): a published SDK return-shape move registers in the ADR-0087 ledger, which already carries @objectstack/client entries of this class (entries/semantic/17.client-delete-result-success.ts, 18.client-meta-reset-result-reset.ts) and which PR #14526 drove end to end. Verbatim reply: 「15622 也移交了；其他同意」 — D is adopted as recommended.

Ruled: D. The oauth.applications.delete change (declared return any → void, observable behaviour always-reject → resolve) is a published SDK return-shape move whose only channel to an untyped caller is the ledger entry — the same reason entries 17 and 18 give for themselves. It carries <!-- adr-0087: registered <entry-id> --> with a semantic ledger entry, exactly as PR #14526 did for #13079. The registered marker names a ledger id, not a symbol, so the reference-reader defect #15627 does not block it.

Not taken: A and C (both edit docs/adr/** to describe a case that already has an honest disposition, and both remain unspellable until #15627 lands); B (a seventh category: new vocabulary, ADR addendum, fixtures, for a class the ledger already serves); E (a red required check on a p1 with a hand-written waiver — the prose-special-case growth this whole family of cards exists to stop). The sixth category's D8 text — "the only thing that moved is a type annotation" — is accurate as written and is not widened; a diff that also moves the body is not a type-surface-only change, and now has a named home.

#15627 (bare-identifier reference resolving to the first same-named member) is a real gate defect and proceeds on its own p1 grading, independent of this ruling; it is not a precondition of anything here.

Execution (domain:cli seat, on PR #15675's existing branch): add the semantic ledger entry under packages/spec/src/migrations/entries/semantic/ (cross-lane touch on packages/spec, the same shape #14996 → #14526 used — the domain:spec seat is informed by this comment, not asked to re-approve), switch the changeset marker to registered, keep **BREAKING**, re-run check-adr-0087-registration to exit 0. Clause-② yes is already declared; the review of record is the cli seat's own at-tier review. #15451's pm:awaiting-maintainer comes off in the same stroke.

State transition, same stroke: needs-user-decision stripped; priority:p1, domain:devx retained; closed completed. Ledger: objectstack director seat post #12708, summon #14.

⭐ Addendum — a FIFTH route the escalation did not enumerate: runtime-interface-only

⚠️ This may change the decision, so it is going up before you rule rather than after.

The escalation on this card enumerated three closed routes (type-surface-only, no-migration-prescription, dropping the BREAKING token) plus two repair options (A: fix the addressing; B: amend D8). Reading the gate's own refusal output on PR #15675 just now, it prints six valid categories, and one of them was never considered by either the implementing agent or this seat:

<!-- adr-0087: not-required (runtime-interface-only path/to/file.ts#Symbol) why -->

Why it is plausibly the right category here

#15451 is not a type-surface narrowing. It changes oauth.applications.delete's runtime behaviour — from rejecting with SyntaxError on every successful delete to resolving — on a client method whose declared return moves from a ledgered any to void.

And the gate's own WHY text describes exactly this shape as the category's reason for existing:

For a surface with no spec schema — ctx.user is only a runtime TS interface — there is no tombstone and no schema rejection either, so the ledger entry is the ONLY channel that reaches an upgrader.

@objectstack/client's oauth.* family has no spec schema and no tombstone. That is the same shape.

⚠️ But it may be blocked for the IDENTICAL mechanical reason — and that is the point

runtime-interface-only takes a path/to/file.ts#Symbol reference, so it goes through the same parseSymbolRef that closed type-surface-only: a bare identifier resolved to the first same-named definition, and packages/client/src/index.ts declares ten members named delete.

⇒ If that is confirmed, it strengthens option A considerably: the addressing defect is not blocking one category, it is blocking every category that takes a symbol reference — two of the six. That is a materially different fact from the one the four-axis analysis was written against.

⇒ If instead runtime-interface-only accepts a reference form that disambiguates (or the ambiguity happens not to bite for this member), then the p1 needs no ADR change and no gate change at all — just the right marker — and both A and B become follow-ups rather than blockers.

⛔ What I am NOT doing

I am not choosing the category, and I am not writing the marker. ⛔ Picking a disposition is exactly the act ADR-0087's sixth category exists to constrain, and the #8277 precedent (an exemption held on a detector miss rather than a positive finding) is the failure mode. This is surfaced as a missing option, not as an answer.

⇒ The measurement that settles it is small and mechanical: does parseSymbolRef reject packages/client/src/index.ts#delete for runtime-interface-only the same way it does for type-surface-only? I can dispatch that measurement on your word — it is a read, not a change.

Current cost of the block, for calibration

PR #15675 is red on Check Changeset solely for this reason (check-adr-0087-registration: "declares a breaking change (BREAKING, bang) but no adr-0087: disposition marker"). Every other check on that PR is green. It is the lane's only priority:p1, and it is the fix for a method that rejects on every successful delete — a caller who retries then fails differently because the row is already gone.
