[finding] ADR-0090 D10 rule 4 declares `performed_by` + `on_behalf_of` + RUN ID — PR #18371 delivers the first two, and the third has no carrier anywhere on the request path

[os-warren]

Filed by the domain:spec execution seat (#6017), session_01KB5PFtxuy1x3dcR5gxudx6, 2026-09-16T05:2xZ, from an os-dev round's out_of_scope_findings. ⛔ Not claimed, ⛔ not dispatched. Grading is triage's. ⛔ This seat did not run a dedupe search (per 「立卡者不查重,只附查重词」).

Measured by the #17022 round (report 5692315422), which deliberately did not build this half.

The gap

ADR-0090 D10 agent rule 4, verbatim: 「Dual attribution: every write records performed_by (agent) + on_behalf_of (user) + run id; explain (D6) reports both sides of the intersection.」

PR #18371 (card #17022) delivers performed_by and on_behalf_of. The run id has no carrier anywhere on the request path.

• ExecutionContext.traceId is declared, but it sits in NonEntryExecutionContextField ⇒ no transport entry point resolves it.
• The only traceId producers in the tree are the observability request-context and the logger — neither is on the authorization path that stamps an audit row.

Why it was NOT folded into #17022

⛔ Deliberately not declared there: a carrier nothing populates is the ADR-0049 defect that card exists to close. Declaring a run-id key that no door mints would reproduce, in the same PR, the exact class of defect being fixed.

The MCP door must mint one. That is a different file face from #17022's five, so it is a successor rather than a half-build.

⚠️ Both shapes #17022's dispatch named covered the two-sided attribution only; neither reached the run id. The previous round on that card recorded the same gap, and it is still open after #18371.

Carrier

判据 (b):ADR-0090 D10 规则 4 逐字要求 performed_by + on_behalf_of + run id;前两者已由 PR #18371 交付,第三者在整条请求路径上没有载体(ExecutionContext.traceId 落在 NonEntryExecutionContextField ⇒ 无传输入口解析它;树上仅有的两个 traceId 生产者都不在盖审计行的授权路径上)。

类型判 Task,⛔ 不是 Feature —— 这一步要说清楚。 给请求路径加一个新的入口字段,形式上像「扩大公开面」;但接受集的裁决 ADR-0090 已经做过了,它逐字写明每一次写入都要记 run id。⇒ 本卡是落实一条既有裁决,⛔ 不是请求一条新裁决。人类底线管的是「谁来决定」,而这件事已经决定过了。
⚠️ 但承接席若发现落实它必须改动传输层的公开形状(而非只是把既有字段挪进入口集),那一刻就回来找维护者,⛔ 不要自行扩面。

p2:契约被量为假、且缺口今天就在产(审计行正在不带 run id 落库);但⛔ 没量到任何一次因缺 run id 而查不下去的取证事件 ⇒ 无实测事故链。

⭐ 交付席 #17022 有意不把这一半折进去,本席复核认可,并认为这是本班反复点名那条纪律的正面范例:它写明「a carrier nothing populates is the ADR-0049 defect that card exists to close」—— 在关掉某一类缺陷的同一个 PR 里再造一个同类缺陷,是最难被发现的那种回归。 ⇒ 一次 PASS 明确留开的东西必须有自己的载体,本卡就是那个载体。
