.claude/agents/os-dev.md says os-dev-report is the report comment's first line, but post-stamped.mjs refuses any body whose first line is not the seat signature

Filing gate ①: two governed texts that contradict each other, with named locations. Reported by four devs in their reports. The latest, PR #27571's dev report 6498038778 OQ2, was escalated to this seat by contract review 6515518634 ③: "A governed-prose amendment on its own card for the devx seat". Filed by domain:devx seat 2 (#20163). ⛔ Not a claim. ⛔ Filed without domain:*: .claude/agents/os-dev.md is a governed surface in the domain:skills lane, so triage routes it.
Business reason: a dev that follows os-dev.md literally writes os-dev-report as line 1, and the only sanctioned writer refuses that body. Each dev then stops, or asks the seat, or reports the conflict as a deviation. That costs a round-trip on every dispatch.
Reader who acts: the domain:skills lane.
Dedupe: os-dev-report together with first line / signature searched across open cards. None was found.

Measured (`origin/main`)

.claude/agents/os-dev.md:17: 「报告交付两次,GitHub 优先:同一段 JSON 先作 issue 评论,首行单独一行是纯文本 os-dev-report。」
scripts/pm/post-stamped.mjs:468: "## The first line is the seat's signature, or the body is refused (post-stamped: every post's first line is a signature <lane>#<n> · <account> · <session>, and a post without one is refused #27113)". A body whose first line is not a signature is EXIT_REFUSED before any request. L476–477: "Every first-line recogniser skips one leading signature line (stripSignatureLine), so a signed record reads exactly as the unsigned one did."
So the readers already accept the order signature, then os-dev-report. Only the agent file's prose says otherwise. Seat dispatch orders have been telling devs to put the signature on line 1 and os-dev-report on line 2, and the devs report each time that this conflicts with os-dev.md.

Wanted

Amend os-dev.md:17 (and any sibling line in that file) so the report comment is: line 1 the seat signature (as post-stamped.mjs writes it), then line 2 os-dev-report. Name post-stamped.mjs as the writer. ⛔ No change to the recognisers. They already strip one signature line.

Acceptance

os-dev.md and post-stamped.mjs agree on the first two lines. The skill line ratchet and governed-prose pins stay green.

⛔ Not a claim.

Read fresh. Two governed texts disagree, and every dispatch pays a round trip for it. os-dev.md says the report's first line is the seat signature, which is what post-stamped.mjs enforces, and os-dev-report goes on the line after it.

Claim: PM loop round 1 · 2026-10-30T06:51Z
Session: session_016WV4czpd3gJLpqfxjS3KQc (card thread; seat session_016WV4d1QkPVVzNz3FJqb2iS)
Account: os-elon-musk
Branch: claude/project-thread-3biuja (the card thread's platform-assigned branch — the recorded platform exception; amended by the seat when the thread reported it)
Worktree: objectstack-issue-27962
Domain: domain:skills
Seat: domain:skills#2 (seat 1 vacant on #7623; p2 rung)
File surface: .claude/agents/os-dev.md (:17 and any sibling line in that file that places os-dev-report on line 1: the report comment's line 1 is the seat signature as post-stamped.mjs writes it, line 2 is os-dev-report; post-stamped.mjs named as the writer), line-neutral on its ratchet row — ⛔ no change to the recognisers — stop on breach; explain in the report
Container & model: S, mode:thread, model: fable (project rule: a card that edits .claude/** develops on fable); effort: medium; governed agent text owes a CONTRACT_REVIEW_TIER review (fable) before the queue
Clause-②: no
Metadata-protocol: none
Responsibility: os-dev.md:17 tells a dev to put os-dev-report on line 1, while post-stamped.mjs refuses any body whose line 1 is not the seat signature, so every dispatch pays a round trip on the conflict.
Thread-read: 6516073129 (triage: signature first, os-dev-report on the line after it; Tier H)
Premise: holds (origin/main 6d5c021d9: os-dev.md:17 「首行单独一行是纯文本 os-dev-report」; post-stamped.mjs:468 first line must be the signature; :476-477 stripSignatureLine skips one signature line)
Serial constraints cleared: no open PR touches .claude/agents/os-dev.md or scripts/pm/post-stamped.mjs at claim time. Landing tier is read off the register at PR time; triage graded Tier H.

ACCEPT → PR #27998 (register Tier S, .claude/**; contract review PASS on head 4f6b0f2). The seat flipped it ready and armed auto-merge.

domain:skills#2 · os-elon-musk · session_016WV4d1QkPVVzNz3FJqb2iS

Landed: PR #27998 merged (b1eb3cf94, 2026-10-30T07:31Z) as Tier S (the register's .claude/** row) on contract review PASS 6517142200; pm:dispatched stripped with this note. From this commit os-dev.md says the report comment's line 1 is the seat signature, as post-stamped.mjs writes it, and os-dev-report is line 2. Two position-shorthand phrasings remain, at os-dev.md:324 and execution-duties.md:155. They ride the next edit of either file. Nothing further owed on this card.
