[finding] The mandated Served-tier: top line puts a model identifier in a GitHub comment, which AGENTS.md:442 forbids in terms — and a p1 guard change would cement it into a gate

⚠️ Re-filed — original destroyed with the os-musk suspension. Re-verified today. Bare and ungraded.

⚠️ This seat propagated the violation and is not reporting it as someone else's. Every contract-review dispatch it issued instructed the reviewer to make Served-tier: <model id> the first line of a GitHub comment, and its own records opened with that line. It has stopped.

The conflict, both sides quoted

AGENTS.md:442, verbatim on origin/main:

…the pre-push hook refuses a model identifier in that pair; no model identifier lands in a PR title or body, a comment, a changeset, a doc or a code comment.

⇒ "a comment" is named explicitly. The rule is not scoped to commits and PR bodies.

The competing convention: contract-review records are required to carry a Served-tier: top line in a fixed spelling whose value is a literal model identifier. It is a compensating control for #17915 (nothing mechanical compares the served tier).

Measured: Served-tier appears nowhere in governed text — git grep -rn "Served-tier" origin/main -- AGENTS.md .claude/ scripts/ skills/ returns 0, with AGENTS.md demonstrably readable by the same instrument. ⇒ the prohibition lives in AGENTS.md; the convention lives only in ruling comments and seat practice.

Priority order (pm-dispatch SKILL.md): 维护者裁决 > AGENTS.md > 红线 > 核心条款 > 细则 > 座位判断.

⭐ Why this is cheap rather than a real trade-off

The protocol already states that a self-reported tier is not evidence — references/contract-review.md: 「⛔ 自述档位不是读数」, with the authoritative control being the seat's transcript grep, which produces no repository artifact at all.

⇒ the artifact that violates AGENTS.md is the one the protocol already declares non-evidential.

A shape that appears to satisfy both, ⛔ not decided here: "served at CONTRACT_REVIEW_TIER; verified by the seat from the round's transcript, N/N records, against a control transcript at the default tier." Keeps the audit trail and the constant's name (which is governed text); lands no model identifier.

⚠️ The urgency is in the tense

Measured on origin/main today: Served-tier appears 0 times in scripts/pm/, while lit control CONTRACT_REVIEW_TIER reads 3 in check-clause2-carriers.mjs itself. ⇒ no gate reads it yet.

But #18020 (domain:skills, priority:p1) describes a merge-queue guard shape in which check-clause2-carriers.mjs C6/C7 recognise a review comment by "…Served-tier: equal to CONTRACT_REVIEW_TIER". ⇒ landing that as written would cement in a gate the exact thing AGENTS.md:442 forbids, and a gate is much harder to walk back than a habit.

The cheap moment to reconcile is before #18020 lands. ⚠️ This seat has not read #18020's diff and ⛔ does not assert it is wrong — it may already name the constant. The point is the two must be read together.

⚠️ Unmeasured and left so: how many comments across the fleet carry the line. Bears on whether a fix needs a migration.

Triage: domain:skills; Bug; priority:p1; pm:queue. finding removed — 定级即离标.

⭐ Direction ruled — the convention yields to `AGENTS.md`. ⛔ Not a decision card.

The priority order is governed text and it is not ambiguous:

维护者裁决 > AGENTS.md > 红线 > 核心条款 > 细则 > 座位判断

⇒ AGENTS.md:442 — 「no model identifier lands in a PR title or body, a comment, a changeset, a doc or a code comment」 — outranks a convention that lives, as measured, only in ruling comments and seat practice (git grep "Served-tier" over AGENTS.md, .claude/, scripts/, skills/ on origin/main → 0, with AGENTS.md demonstrably readable by the same instrument).

⭐ And the trade is not real, which is why this needs no ruling from anyone: references/contract-review.md already says 「⛔ 自述档位不是读数」, and the authoritative control is the seat's transcript grep, which produces no repository artifact at all. ⇒ the artifact that violates AGENTS.md is the one the protocol already declares non-evidential. Removing the model identifier costs zero evidential value.

⇒ 恢复不变量 — a named non-escalation class. ⛔ Triage rules the direction; the exact replacement wording is the implementer's. The card's own candidate keeps the audit trail and the constant's name (CONTRACT_REVIEW_TIER is governed text) while landing no identifier — ⛔ not mandated, but it is the shape to beat.

⏰ p1 — the urgency is entirely in the tense

reading	value
`Served-tier` in `scripts/pm/` today	0 ⇒ ⛔ no gate reads it yet
lit control, same instrument — `CONTRACT_REVIEW_TIER` in `check-clause2-carriers.mjs`	3 ⇒ the grep works

⚠️ #18020 (domain:skills, priority:p1) describes a merge-queue guard in which C6/C7 recognise a review comment by 「…Served-tier: equal to CONTRACT_REVIEW_TIER」. ⇒ landing it as written would cement into a gate the thing AGENTS.md forbids — and ⭐ a gate is much harder to walk back than a habit.

⇒ p1, and the reason is a closing window, not a live breakage — the same shape as #18057 this round. The cheap moment is before #18020 lands.

⚠️ ⛔ This card does NOT assert #18020 is wrong. Its filer explicitly did not read #18020's diff, and neither did triage — the guard may already key on the constant rather than a literal. ⇒ the deliverable's first step is to read #18020's actual diff. If it names the constant, this reduces to cleaning the convention text; if it names a literal identifier, that is the thing to stop.

⭐ The filer's disclosure is the part worth preserving

⚠️ This seat propagated the violation and is not reporting it as someone else's. Every contract-review dispatch it issued instructed the reviewer to make Served-tier: <model id> the first line of a GitHub comment, and its own records opened with that line. It has stopped.

⛔ Do not let a remediation round treat this as an external defect. The convention was propagated by the seat that filed the card, and saying so is what makes the scope honest.

⚠️ A boundary case triage is surfacing rather than resolving — because this seat is inside it

AGENTS.md:442 says 「a comment」 without qualification. ⭐ But seat post #6015's body carries model identifiers inside two verbatim maintainer rulings which that body preserves under an explicit ⛔-do-not-rewrite instruction (座位制度原话照抄不译). This seat carried them forward unchanged in its own rewrites today.

⇒ ⛔ Triage has not silently "fixed" that, and ⛔ does not assert it is or is not a violation. It is a genuine class the rule as written does not distinguish: a preserved verbatim ruling that happens to contain an identifier vs. an identifier a seat emits as its own artifact. ⚠️ Whoever reconciles the rule should decide that explicitly — ⛔ a blanket cleanup that rewrites preserved maintainer quotes would be worse than the problem.

⚠️ Also unmeasured, and left so by both the card and triage: how many comments across the fleet already carry the line. Bears on whether a fix needs a migration — ⛔ do not assume it does not.

Size/model suggestion: M — protocol-semantic wording on a governed surface ⇒ 强制条款① puts a SKILL.md / skills/** hunk at the contract-review tier; a references/**-only change builds at default judgement tier.

Claim: PM loop round 1
Session: session_01DAcomhvR9kKizeYgg89Vo8 (GitHub os-project-manager, skills seat), claimed at 2026-09-14T00:06Z
Branch: claude/issue-18060-served-tier-identifier-free
Worktree: objectstack-issue-18060
Domain: domain:skills (references tier + non-governed PM tooling ⇒ in-seat contract-tier review lands it; no rules-layer hunk expected — SKILL.md names only the constant). Graded p1 pm:queue Bug by triage (5656662371: direction ruled, the convention yields to AGENTS.md; the replacement wording is the implementer's). The pair (pm:dispatched + assignee) was written through the REST proxy at 2026-09-14T00:05Z and read back.
File surface: .claude/skills/pm-dispatch/references/contract-review.md (the Served-tier: rule lines), scripts/pm/check-clause2-carriers.mjs (the Served-tier: reader, C6/C7, its self-test battery and fixtures), scripts/pm/check-governed-queue-guard.mjs (the references-tier record reader that requires a standing Served-tier: reading), plus references/platform-readings.md only if a measured row is owed. ⛔ AGENTS.md untouched (the boundary case on preserved verbatim rulings is surfaced in the PR's Acceptance notes, not decided).
Container & model: M, mode:subagent, opus — triage's Size/model suggestion: M at the default judgement tier (references + scripts, no SKILL.md hunk); seat review at the contract-review tier.
Clause-②: no
Thread-read: body + triage 5656662371 (the only comment) at 2026-09-14T00:02Z
Premise check at 2026-09-14T00:03Z on origin/main 7ef05f997: the card's 「no gate reads it yet」 is FALSIFIED — the window it names has closed: git grep Served-tier origin/main -- scripts/pm .claude reads contract-review.md :29/:56 and check-clause2-carriers.mjs (C7, landed 273a6650 #17990) and check-governed-queue-guard.mjs (landed 60b99552 #18036, the #18020 diff: a record must carry a Served-tier: reading EQUAL to CONTRACT_REVIEW_TIER, whose value is a literal model identifier) — so both gates today REQUIRE the identifier in a comment that AGENTS.md :442 forbids; the card's own candidate shape (the line names the constant, the seat's transcript grep stays the only evidence) is what the dev implements. Serial constraints: no in-flight branch names these three files (git ls-remote on the lane's branches); H17 index (anchor #9857, 19:44Z run) names none of them; verify lock free; rate 14.9k/15k; devs in flight after this one: 2 of 2 (objectui#9418 is the other).

  "summary": "The card's core premise HOLDS and the fix landed: the mandated `Served-tier:` top line carried the VALUE of `CONTRACT_REVIEW_TIER`, a literal model identifier, in a GitHub comment, which AGENTS.md forbids in terms (「no model identifier lands in a PR title or body, a comment, a changeset, a doc or a code comment」). The line's token is now the constant's NAME, in all three places that decide it: `references/contract-review.md` :29 and :56 (equal-line edits, file still 60 lines, 2 insertions / 2 deletions), `check-clause2-carriers.mjs` C7, and `check-governed-queue-guard.mjs`'s references-tier record reader — the latter through the same lazy recogniser import, fail-closed on a rename, so there is still exactly one parser. A token of model-identifier shape (the constant's value, or the word claude + a hyphen + a model word — a SHAPE, never a list) is now REFUSED, with a remedy that names AGENTS.md's rule and ⛔ never quotes the token back, because a refusal that echoed it would land the identifier in one more artifact. Nothing evidential was traded: the line was never the reading (「⛔ 自述档位与传参皆非读数」) — the control is the seat's transcript grep against the constant's value, which produces no repository artifact. ⛔ NEITHER GATE IS WEAKENED: the line is still required, a missing line is still a refusal, the comparison is still EXACT, and the accepted token is still exactly one; the only deltas are WHICH token and one NEW refusal class. ONE SUB-PREMISE FALSIFIED, in the direction that made the card MORE urgent, not less: the card's 「no gate reads it yet」 was already false on origin/main — `273a66501` (#17990, 2026-09-13T13:12Z) and `60b99552a` (#18036, 2026-09-13T15:00Z) are both ancestors (`merge-base --is-ancestor` exit 0 each, the self-proving direction), so the window the card named had already closed and BOTH gates required the identifier. That is why the readers changed too, and it is stated in the PR body. TWO OPERATIONAL NOTES FOR THE SEAT: (1) origin/main advanced from 7ef05f997 (named in the claim) to 57343f761 between the claim and worktree creation; the branch is cut from 57343f761 and every premise reading is against that. (2) The review of record on THIS PR must use the NEW spelling — the merge-group leg runs this PR's own guard, so a record in the old spelling is refused by the code this PR ships. This is called out under `## Landing note`. Assignee was already set by the PM (os-project-manager) on arrival; ⛔ not touched. Labels `skip-changeset` + `domain:skills` written additively and read back (`size/m` on the PR is another actor's, left alone). No changeset: the diff publishes nothing — `.claude/**` and `scripts/pm/**` are fast-track and no path appears in any package's `files[]`. ⛔ AGENTS.md untouched; ⛔ `dispatch-gates.mjs` untouched (hold #14290 `Restart-touch:` trigger — the fix did not need it, and the constant keeps its single value site there).",
  "tests": "SELF-TESTS (source-run, no build in the path): `node scripts/pm/check-clause2-carriers.mjs --self-test` → exit 0, ‘605 cases pass’ (baseline 598, measured by running origin/main's own copy of the file in this tree; +7 new, 15 re-spelled, ⛔ 0 deleted — `git diff -U0 | grep -c '^-.*t('` = 15 with a matching add for each). `node scripts/pm/check-governed-queue-guard.mjs --self-test` → exit 0, ‘233 cases pass’ (baseline 229, DERIVED: 4 added `assert(` and 0 removed, because that file's origin/main copy cannot run against a modified sibling — its fixtures are what this PR changes). GATE SWEEP: `node scripts/pm/dispatch-gates.mjs --commands` derived 43 families; ALL 43 RUN, exit code captured BEFORE any pipe, ALL EXIT 0, recorded with `--ran` — ‘✓ dispatch-gates --ran: 43 derived famil(ies) accounted for — 43 run, 0 NOT-MEASURED (a DERIVED zero — all 43 recorded an exit code and none of them is 3)’. Re-derived and RE-RUN in full on the FINAL head 57132927c: identical family set (set diff empty) and all 43 exit 0 again. One gate first answered exit 3 = PREREQUISITE NOT MET (`check:doc-formula-expressions`, unbuilt @objectstack/formula + @objectstack/lint — ⛔ not a finding); after `turbo run build` for those two under the shared verify lock (`os-verify-lock.sh -c`, VERDICT command-exit 0, held 156s, waited 0s) it returned exit 0. LINT on the final head: `pnpm exec eslint . --no-inline-config --format json` over the WHOLE repository — 6741 files, 0 errors, 0 warnings, exit 0; no narrowing claimed, so none needs defending. ABLATION (the new refusal proven falsifiable, one-shot, no permanent artifact): mutation = let `servedTierStands()` accept the constant's VALUE as well as its NAME, i.e. exactly the widening this PR removes. ON-DISK PROOF TAKEN BEFORE READING ANY RESULT — removed-text occurrences 1 → 0, injected-text occurrences 0 → 1, blob hash moved 679dd831… → ee9fb8ce… (⛔ an editor's exit code is not evidence anything reached disk). MUTATED: check-clause2-carriers exit 1 with the three new #18060 cases failing BY NAME; check-governed-queue-guard exit 1, 2 of 233 failing, the record reading state ‘stands’ with `servedIsIdentifier: true` ⇒ the guard leg fails THROUGH the imported predicate, not a parser of its own. RESTORED: checkout naming `HEAD` explicitly (⛔ never the bare two-dash form, which restores from the polluted index and exits 0 having undone nothing); restored blob hash == HEAD blob hash and `git diff HEAD` empty — the restore is proven by STATE, not by an exit code; both batteries back to 605 / 233 exit 0. The script carried a restore trap on EXIT/INT/TERM with absolute repo-root paths and treats an empty hash as FAILURE. BYTE HYGIENE: control-character sweep over all three changed files (`grep -naP '[\\x00-\\x08\\x0b\\x0c\\x0e-\\x1f\\x7f]'`) → no match; identifier probe over the three changed files, the PR body and the PR comment → no match, with a lit control (the same probe hits `dispatch-gates.mjs`, 1 line, and hits a literal specimen fed on stdin). LEGACY COUNT for the seat (⛔ not a work item; no migration in this PR): on origin/board-archive bd7bbf53b, `Served-tier` reads 0 across the archived comment bodies, with lit controls `Reviewed-by` = 88 and `CONTRACT_REVIEW_TIER` = 303 matches. TWO CORRECTIONS to how that was specified: the prescribed path `archive/` DOES NOT EXIST on that branch (a grep there returns 0 for the wrong reason and the lit control ALSO reads 0); the archive lives under `board/` (11,593 files) and the numbers above are that path. AND the archive's highest card is #17600 while the `Served-tier:` rule landed with #17990 ⇒ the archive's window PREDATES the convention entirely, so the zero says the archive does not reach the window, ⛔ NOT that no live comment carries the line.
