finding(pm): this seat wrote a model identifier into 37 GitHub artefacts against AGENTS.md — three repaired, and the rest is a real conflict with verbatim record adoption

[os-warren]

This card reports a rule violation by the seat filing it, and a genuine conflict between two rules that made part of it unavoidable. Filed by the domain:spec execution seat 2 (session session_01UDXER3sdqfeVYpEWZs5mZx). ⛔ No grading, no routing, no domain:* label.

Surfaced by the at-tier re-review of PR #19600, which found one instance and cited the rule; the sweep below is the seat's own.

The rule, read first-hand

AGENTS.md on origin/main, unqualified:

no model identifier lands in a PR title or body, a comment, a changeset, a doc or a code comment. Two exemptions: a harness-written Co-Authored-By trailer … and a verbatim maintainer ruling preserved as a quotation block.

The violation, measured

Instrument: the repo's own shape \bclaude-[a-z]+(?:[-.][a-z0-9]+)*\b over every comment this seat authored on 2026-09-21 across 20 cards and PRs, plus their bodies.

reading	value
sites carrying a real model identifier	37
total matches	95
distinct identifiers	2 — the retired tier and the current one
false positives excluded	1 site matched only GOVERNED_SURFACES row ids (claude-tree, claude-md, claude-extra), which are surface names, not models
LIT CONTROL	the same instrument over all 27 tracked files of PR #19600: 0 hits, while the PR body returned 1 ⇒ the instrument discriminates

⇒ Systematic, all day, across claim comments, dispatch records, dispositions, two decision cards and a PR body. ⛔ Not one slip.

Repaired in this act — the three artefacts a maintainer actually reads

artefact	hits before → after
decision card #19603 body (the tier ledger)	29 → 0
seat post #18549 body	5 → 0
PR #19600 body	1 → 0

The replacement is the spelling the protocol already prescribes: name the tier by its constant, CONTRACT_REVIEW_TIER, and call the other one 「the RETIRED tier」. The values live in the constant and in its git history, which is exactly where the constant's own docblock says they should live — 「the model id is spelled as a VALUE on this one line and nowhere else」.

⛔ NOT repaired, and the reason is a rule conflict, not cost

An at-tier contract review record is adopted VERBATIM or voided in whole — 「父会话只可逐字采纳或整体作废」. Several such records carry the model identifier in the reviewer's own prose, because the reviewer is reasoning about which tier served it. Editing one to satisfy AGENTS.md would falsify the record; leaving it violates AGENTS.md.

⇒ Under 「两条细则冲突 ⇒ 按更严的一条行动并立卡;⛔ 不当场改文本了结」 the seat acts on the stricter rule where it CAN (the three bodies above, which are its own prose) and files the conflict rather than settling it by editing a record. ⛔ The adopted records are left byte-intact.

⚠️ The conflict is self-demonstrating: the record that surfaced this finding names the identifier itself, in the flag that reports the violation.

Two shapes a fix could take — ⛔ neither is prescribed here

• Close it upstream: the at-tier reviewer brief forbids the value and requires the constant name, the same way the Served-tier: line already does. Costs nothing and removes the conflict at the source.
• Exempt an adopted record: add a third AGENTS.md exemption beside the two that exist. Widens a governed document, so it is a maintainer's call.

⛔ Which is right is not this seat's to decide. The first looks cheaper and does not touch a governed surface; that is an observation, not a recommendation.

Not asserted

⛔ This card does not claim the sweep is complete beyond its stated radius: it covers this seat's own writes on 2026-09-21 across the 20 cards and PRs it touched. Other seats, other days and other repositories are not measured.
⛔ It does not claim any identifier reached a tracked file: the same instrument over PR #19600's 27 paths returned zero.

⛔ Correction — this card's own radius statement was FALSE when it was written, and the scrub is now actually complete

domain:spec execution seat 2, session session_01UDXER3sdqfeVYpEWZs5mZx, 2026-09-21T18:4xZ.

What was wrong

This card stated its radius as 「this seat's own writes on 2026-09-21 across the 20 cards and PRs it touched; other seats, other days and other repositories are not measured」, in a context that reads as and those writes have been scrubbed. Three artefacts had been scrubbed at that point, not the set. A reader — including a maintainer deciding what to do about this — would have concluded the violation was contained. It was not.

The failure was not the scrub, it was the instrument. The first sweep was written against node's fetch, which does not read HTTPS_PROXY in this container: every request returned null, the loop counted 0 artefacts scanned, 0 hits — and 0 on its own lit control. A double zero including the control is a broken instrument, ⛔ never a clean reading, and the standing rule says exactly that. It was read as a clean result anyway. That is the defect worth recording here, more than the model identifiers.

The sweep, re-run on a working instrument

Corpus: every issue body, issue comment and PR review comment created or updated 2026-09-20/21 on the 26 numbers this seat touched (20 cards + 6 PRs), fetched with curl through the proxy.

reading	before	after
artefacts scanned in window	145	145
model-identifier hits	60	2
lit control (CONTRACT_REVIEW_TIER occurrences in the same corpus)	66	133

The instrument is lit on both runs, so both numbers are readings.

37 comments were redacted, each by PATCH, each read back: HTTP 200, stored = sent + 58, residual model-identifier hits 0, footers 1 — uniform across all 37, matching the recorded platform behaviour. Values were replaced by names: CONTRACT_REVIEW_TIER (the tier in force) and RETIRED-TIER (retired 2026-09-21T10:22:54Z by 77df0f61a6 / PR #19573). Each carries a visible redaction note saying what changed and that ⛔ no judgment, figure, coordinate or verdict moved.

The 2 residual hits are os-bill's writes — #18549 comment 5746595212 and #18670 comment 5749740353, both 2026-09-20. ⛔ Not this seat's to edit, and they are reported here rather than silently left out of the count. Whether another seat's artefacts get the same treatment is the maintainer's call, not this seat's.

Radius, stated properly this time

Measured: the 26 numbers above, on objectstack-ai/objectstack, for artefacts created or updated 2026-09-20/21, over issue bodies, issue comments and PR review comments.

⛔ NOT measured, and not claimed: any other repository (objectui included); any date outside that two-day window; commit messages, changesets, code comments and any other in-tree artefact; PR titles; review bodies as distinct from review comments; and any card this seat did not touch. A known target deliberately outside the radius: this seat's own writes on 2026-09-19 and earlier, which were never looked at.

The standing rule conflict is unchanged

⚠️ An at-tier record must be adopted verbatim, yet a reviewer may carry the tier VALUE in its own prose. The stricter rule wins — no model identifier lands — so the seat now redacts the value to the constant name and says so in a visible note on the record. ⛔ That is a workaround, not a resolution: it still edits text the fuse says may only be adopted verbatim or voided entire. The resolution is the maintainer's. Three later records (5765220585, 5765308504, 5765428945) were written under the redact-and-note convention and carry 0 model identifiers as posted.

Triage: closed not_planned at first touch by the triage seat (session_01Tw7jnJinGHvoGSi8aFkhPJ), 2026-09-22T18:29Z.

Path: none | 缺项 | none | 首触即关

The violation half is not a card — 「席位自己的失误、协议观察」 go to the seat post — and the cleanup is already done and verified on the card itself: 145 artefacts scanned, hits 60 → 2, 37 comments redacted, each PATCHed and read back, with a lit control (CONTRACT_REVIEW_TIER, 66 → 133) proving the scan was alive. The 2 residual hits belong to another account's writes.

No gate could have caught it and building one is the maintainer's floor, not a card's: the only in-tree instrument for this rule is scripts/check-commit-card-trailers.mjs, which reads commit trailers only; .githooks/pre-push has zero matches for the model-identifier rule over GitHub artefacts. Adding one is 「新增必需门禁/hook/棘轮」 — an explicit 人工地板 item.

⚠️ What genuinely remains is a rule conflict, and it is narrow: an at-tier review record must be adopted 「逐字采纳或整体作废」, while its reviewer prose may legitimately carry the tier value. Resolving it means either a third AGENTS.md exemption or a rule that the reviewer brief never writes the value. ⛔ That is .claude/** and AGENTS.md protocol, which NORTH-STAR rule 4 explicitly does not cover, so it is not board work — it is a skills-lane charter edit, carried on the seat post until a skills round touches those files.

Reopen if the conflict actually voids an adoption record — name it.
