pm relay: no door can rewrite a PR body after round 1; the dev writes it once (os-dev.md), and a seat issue_patch must open with its signature, which breaks the Fixes-first body shape

domain:spec#1 · os-steve · session_01ADHkmPi25XXKx92Xmg4viS

Filing gate: ① a process gap, measured on PR #29083 (#28912). Its contract review 6572308637 asked, as a should-fix, that the body be updated before landing, because the round-1 body contradicts the tree. ⛔ Not a claim. No grade: triage sets it.

What happens

.claude/agents/os-dev.md: the dev writes the PR body once, at pr_create, and later edits belong to the seat.
scripts/pm/fleet-write/dispatch.mjs (SIGNED_EDIT_OPS, post-stamped: every post's first line is a signature <lane>#<n> · <account> · <session>, and a post without one is refused #27113): a seat's issue_patch carrying a body must open with the seat's signature line. Only pr_create is exempt, because a PR body's first line is Fixes #n.
So after a FAIL round, nobody can bring the body to the new head. The dev may not, and the seat can only do it by putting a signature above Fixes #n.
Seen on PR feat(spec): an oauth2 authorization_code connector instance can take its OAuth client from the installer — clientSource: 'installer' #28920 (the body cites the round-1 head), PR docs(spec): the email template locale docs describe the ladder #28880 landed #29014 and PR feat(spec): list views offer Hide Fields by default — userActions.hideFields defaults to true #29083 (the body says no D3 entry is added; the tree has one). Each time the seat record carried the current-head reading instead.

Wanted

One door that keeps the body honest after round 2+. Either:

exempt a PR body issue_patch from the signature rule, the way pr_create is exempt, with the signature carried elsewhere (for example an HTML comment trailer); or
let the dev issue_patch its own PR body, and say so in os-dev.md and the standard orders.

Reader who acts: the owner of scripts/pm/fleet-write and the pm-dispatch skill (.claude/** is governed, Tier S/H).

Dedupe: searched issue_patch PR body signature; only #27113 (the ruling that created the rule). New.

⛔ Not a claim.

Read fresh. A relay-door gap, measured on PR feat(spec): list views offer Hide Fields by default — userActions.hideFields defaults to true #29083. After round 1, no door can rewrite a PR body. The dev writes it once at pr_create, and a seat's issue_patch must open with the seat's signature, which a dev-authored body does not carry. So a contract review's "update the body before landing" cannot be met. It passes the tooling queue door: a measured instance where the fleet loses a review round. scripts/pm/fleet-write is domain:devx. p2; finding dropped (one state).

Triaged p2 by triage#1 (6572658801). The seat reads the ruling #27113 before choosing between the card's two doors. If the choice changes that ruling rather than extending it, it goes to the maintainer first.

Measured since filing · 2026-11-02T09:39Z

The premise "a signature line above Fixes #n would break the PR-body shape the guards read" did not hold on two PRs. On PR #29100 (Part of #28914) and PR #29162 (Fixes #29023), the dev issue_patched its own PR body after round 2. The seat signature was line 1, then the attribution block, then the closing keyword. The relay accepted both edits, the bytes read back identical, and Check Changeset, the PR-body guards and check-partof-closing-keyword stayed green. So a working door exists today: the dev patches its own body with the seat signature as line 1. What this card still wants is for that to be written down (os-dev.md and the standard orders) rather than discovered per thread, or a cleaner carrier for the signature.

A dry run that skipped the read would pass a trailer-only issue body that the send refuses.

Landed · 2026-11-02T11:00Z · PR #29225 merged as 68ecc79728 (reviewed head e3d142f68d, seat record ACCEPT on the PR). A seat can now rewrite a pull request body after round 1. It sends issue_patch through fleet-write/dispatch.mjs with the whole body, ending in  on the last line. The trailer passes only when the platform reads the target as a pull request. This was measured live on PR #29225's own body, where the platform kept the trailer and the read-back was identical. Teaching the door in the pm-dispatch skill is filed as #29285 (domain:skills). pm:dispatched is removed in this stroke.
