Report 5678039238 on PR #18292 (head6fbb74e8) reviewed by the checklist: files changed = the claim's surface exactly (scripts/pm/post-stamped.mjs);Fixes #18289alone beside a closing keyword;skip-changesetread back;mcp_calls0 — every write through the REST proxy orlabel-write.mjs; gates 32 / 32 / 0 / 0 by--rantwice (pre-merge and merge commit), battery 1730 pass twice; the seat's re-run on a detached worktree of the head: self-test 186 / 10 batteries (152 / 9 on main), both defect halves — the NaN instant and the rolled-over date — render onorigin/main's tool and are REFUSED on the head with the calendar row, the three controls render, ESLint 0, wiring and watch-hint green (record 5678109551 on the PR names each). The fix goes one measured step past the card (the rollover half) on the dispatch's own instruction. Deviations (5) answered one by one in the record. Out of scope routed: the read-sidelastWriteStamprollover → #18293 (serial behind this PR). Landing: in-seat once CI on the head is green (Lint and Type Check still running at 2026-09-15T09:45Z) — ready through the CCR route + auto-merge SQUASH; the card stayspm:dispatcheduntil the three landing readings.

Readings at 2026-09-15T10:20Z:git log origin/maincarries(#18292); the queue refrefs/heads/gh-readonly-queue/main/pr-18292-*is gone from origin; theremoved_from_merge_queueevent is on the timeline. Non-governed landing: record 5678109551 PASS, ACCEPT on this card, provenance on the PR; the seat flipped it ready through the CCR route and armed auto-merge SQUASH at 2026-09-15T09:58Z. Now onorigin/main:post-stamped.mjsrefuses a quoted stamp that names no real instant — both the NaN half and the rolled-over half — in the one scan beside the direction rule; self-test 186 cases across 10 batteries; the header states both grains. Residue (pm:dispatched, assignee) stripped throughlabel-write.mjsand read back; #18293 (the read side, same file) is unblocked and dispatches next.

Refuse a quoted stamp whose payload does not parse to a real instant (NaN span ⇒ REFUSED with the span, on
--dry-runtoo), in the same scan that PR #18286 added; self-test cases: an impossible month, day, hour and minute each; a control with a real instant at both grains the tool accepts (minute and second — the header prose says minute only, which the dev noted as narrower than the contract; fix the prose in the same PR if it is the same paragraph).scripts/pm/post-stamped.mjsonly; serial behind PR #18286 (same file, same scan).Grading (lane
