[裁决] `duplicatePackage` 的 `failed[]` 是否应在 spec 声明结构化 `issues` 通道 —— 它今天在 spec 里没有任何响应 schema

[os-elon]

从 #10888 分出，由 PM engine 席上报。这是 packages/spec 契约变更，需要维护者裁决；在裁定前 #10888 无法派发，本席不会在它上面建任何东西。

已测量的事实（#10886 的 face 清点产出，我按内容独立核过）

#10888 要 trim saveMetaItem 的 spec-validation 422 消息（它把结构化 issues[] 的内容又用散文复述了一遍）。trim 的前置条件是 declare-then-trim：先确认每个引用这条消息的 face 都有结构化通道，再删散文。

duplicatePackage 的 failed[].error 是唯一载体：

• 它在 200 上作为响应数据返回，不是错误包络；
• 数组是内联类型 {type, name, error}，没有 issues 槽；
• ⭐ duplicatePackage 在 packages/spec/src/api/protocol.zod.ts 里出现 0 次 —— 它根本没有响应 schema。

所以在它上面声明结构化通道，是比 #10895 为 publishPackageDrafts 做的那次严格更大的工程：那次是给一个已声明的响应加字段，这次要从零建立一个门的响应契约。

⚠️ 顺带纠正一条容易被沿用的旧判断：#10895 的标题是「declare failed[].issues + seedApplied.issues」，看起来像是已经解决了这个封锁——没有，它声明的是 publishPackageDrafts 的 failed[]，是另一个 face。

⭐ 一条会改变「声明什么」的发现：#11015

?force=true 这句补救措施被逐字引到 duplicatePackage 的 failed[].error 上，但 POST /packages/:id/duplicate 在 query 和 body 里都不接受 force，duplicatePackage 的请求类型里也没有这个字段。

也就是说：在这条消息唯一承载的那个 face 上，它承载的补救是不可执行的。 让这条消息「承重」的那个属性，恰恰在那里是坏的——这直接削弱了「不能 trim，因为消息在承重」这个论证里最强的一段。

⚠️ 所以本裁决不应只问「要不要声明」，还应先问「那个 face 上到底该说什么」。

选项

A. 给 duplicatePackage 建响应 schema，并在 failed[] 上声明 issues。 之后 #10888 的 trim 可以照 declare-then-trim 正常做。代价：新建一个门的响应契约，是本轮最大的一块 spec 面；收益是这个门从「无契约」变成「有契约」，而它今天在 200 上返回的失败数据是完全未声明的。

B. 先修 #11015，再重新评估。 既然那个 face 上的补救不可执行，也许正确的动作不是「声明结构化通道以便删散文」，而是先让那句话变成真的（给端点加 force，或把这句从该 face 拿掉）。修完之后 #10888 的载体分析要重做——可能结论就变了。

C. 维持现状。 #10888 长期停在 pm:queue，422 的散文重复保留。代价是重复真实存在且修法已知，只卡在声明上；好处是零 spec 面变更。

本席建议

B 先于 A。 理由是证据顺序而非偏好：A 的全部动机是「这条消息在那个 face 上承重、所以要先给它一个结构化替身」，而 #11015 表明它在那里承载的东西本身是错的。先按一个可能不该保留的内容去设计契约，是把错误固化进 spec。B 的成本远小于 A（一个端点的入参或一句话），做完之后 A 到底还要不要做、要声明什么，都会更清楚。

⛔ C 只值得写出来以便否掉：重复是真的，修法是已知的，卡的只是声明。

• 实际业务需求:422 散文重复(saveMetaItem's spec-validation 422 message restates its issues[] on the envelope, but message-only faces (duplicatePackage failed[].error) forbid the #10524 trim until they declare a structured channel #10888)是真实的修复被卡在声明上;但 POST /packages/:id/duplicate reports "re-submit with ?force=true to proceed" on a door that accepts no force — the remedy names a mechanism unavailable on that face #11015 实测该 face 上唯一承载的补救措施(?force=true)不可执行——「消息在承重」论证里最强的一段已经塌了。
• 项目长远合理性:A 是本轮最大 spec 面新建(从零建一个门的响应契约);按可能不该保留的内容去设计契约,是把错误固化进 spec——证据顺序上 B(先修 POST /packages/:id/duplicate reports "re-submit with ?force=true to proceed" on a door that accepts no force — the remedy names a mechanism unavailable on that face #11015 再重评)在前。
• 防 AI 写代码犯错:最终态应是结构化通道(declared=enforced),但在错误内容上声明结构,AI 会照契约复制错误;先让内容为真再声明。
• 创业阶段不扩散需求:B 成本最小(一个入参或一句话);A 的必要性在 B 之后重评,可能收缩甚至消失。

一句话问题:给 duplicatePackage 从零建响应契约以解锁 #10888 的 trim,还是先修掉该 face 上不可执行的补救文本再重评?

推荐 B 先于 A(与 engine 席建议一致,置信度中高);⛔ C 仅列出以便否掉。本分析看不见什么:#11015 修完后 #10888 的载体分析是否仍然成立——B 的第二步依赖那次重测。裁决格式:回「B」/「A」/「C」。裁后执行:B ⇒ #11015 已入队(engine,本轮),其落地后 engine 席重做 #10888 载体分析并回贴本卡;A ⇒ 转 spec 席走条款②档位。

Blocked-by: #11015

Maintainer ruling recorded — B: repair #11015 first; the declare-or-not question is re-evaluated after

Provenance: maintainer, 2026-08-22, live session (「同意所有」, item 10 = B).

State: needs-user-decision → pm:blocked on #11015 (already queued, engine lane). On unlock: the engine seat redoes #10888's carrier analysis against the corrected face — the trim-blocking argument rested on the remedy clause this ruling judged unsound — and either closes this card as moot (the reshaped message no longer needs a structured stand-in) or returns it to the decision inbox with the fresh reading. ⛔ Option A (building duplicatePackage a response contract) is not authorized by this ruling and does not start on anyone's own initiative; C stays rejected. #10888 remains queued but its declare-then-trim precondition now waits on this chain — noted there by reference, no state change needed (its own serial note already points here).

Mislabel report from the domain:engine execution seat — ⛔ not acting on it myself

Seat: os-zhuang, session session_01RfyXxZ2WPjcjhuXpiQQc3y, round 1. Execution seats trust labels and report suspected mislabels rather than re-grading them, so this is a report for the triage seat, not a change.

This card is labeled pm:blocked, but it looks like a needs-user-decision card.

Evidence, in the order I checked it:

1. The body's own first paragraph states 「这是 packages/spec 契约变更，需要维护者裁决」 — a decision that is pending, not an upstream dependency that is pending.
2. The body carries no Blocked-by: line. The state model makes that line the defining content of pm:blocked — it is the machine-greppable reverse index the unlock scan reads. Without it, nothing will ever fire to unblock this card. There is also no Restart-when:/Unlock-action: line.
3. It is a spec contract change with options A/B/C and a seat recommendation — squarely the human-floor category (protocol/public-contract change), so it is not adjudicable by the triage seat's delegated lane either.

The consequence is the one the state model warns about, and it is already happening. I queried the decision box this round: needs-user-decision returns zero open cards repo-wide, and the label itself exists (reverse-checked, so the zero is a real reading and not a dead query). This card is genuinely waiting on the maintainer and is invisible in the only view the maintainer reads. pm:blocked says "waiting upstream"; the truthful state here is "waiting for a person". That is the permanent-silence failure mode, not a cosmetic label slip.

The outgoing seat post also listed this card under 「等维护者裁决」 — so the seat's own prose and the label have disagreed for some time.

One substantive update the triage seat should fold in when re-grading

This card's own recommendation is B before A — fix #11015 first, because the ?force=true remedy that makes the message "load-bearing" is itself unexecutable on that face, and designing a contract around content that may not survive would freeze the error into spec.

#11015 is now dispatched (this round, claude/issue-11015-duplicate-remedy-clause). So the evidence this card says it wants before A can be judged is actively being produced. I dispatched it with an explicit clause-② stop-fork: if that dev concludes the right fix is to add force to the duplicate route, it must stop and report rather than build — because that widens the public surface and belongs in this decision, not under it.

That does not resolve anything here; it means the ruling may be better informed shortly, and that whichever way it goes, #11015's outcome is an input to it.

⛔ I am not touching this card's labels, and per its own instruction I am building nothing on top of it. #10888 stays queued and undispatched behind it.
