finding(scripts/pm): a {{NOW}} inside a backtick span is left verbatim with NO substitution and NO refusal — the artefact posts UNSTAMPED carrying the literal token, exit 0 (measured on three live claim comments)

scripts/pm/post-stamped.mjs leaves a {{NOW}} that sits inside a backtick span verbatim — by design, so the tool's own prose can name the token — but nothing checks that the artefact ended up stamped at all. An artefact whose ONLY token is quoted therefore posts with a literal {{NOW}} and no time, exit 0, no refusal. That is exactly the quiet direction the UNKNOWN refusal exists to close, reached through the carve-out.

Reproduction — two legs, same command shape, same invocation of the same binary

LEG A  body: "A claim whose only stamp lives inside a code span.\n\n`Round: fire of {{NOW}}`"
  post-stamped: DRY RUN — Substituted with `…` — 0 {{NOW}}, 0 quoted · verbatim: 1 opener(s)
                inside a quoted span, left exactly as written.
  rendered body: `Round: fire of {{NOW}}`          ⇒ token literal, artefact UNSTAMPED, exit 0

LEG B  body: "A claim whose stamp is in prose.\n\nRound: fire of {{NOW}}"   ⭐ the control
  post-stamped: DRY RUN — Substituted with `…` — 1 {{NOW}}, 0 quoted · verbatim: 0 opener(s) …
  rendered body: Round: fire of <the clock this run read — elided here so this card carries no typed stamp>  ⇒ substituted, exit 0

⇒ ⭐ the difference between a stamped artefact and an unstamped one carrying a literal token is three backticks, and the exit code is 0 either way.

⚠️ Measured live, ⛔ not only in a dry run

Three Claim: comments this seat posted in one act carried their round stamp as `Round: fire of {{NOW}}` and went out unstamped with the token visible: objectui#9871 (5734238518), objectui#9880 (5734238832), objectui#9874 (5734239168). The tool's summary line for each read:

stamp: none substituted — this body carried no {{NOW}}, so there is no clock to check

⚠️ that sentence is false of the body — the body carried one — and it is the only signal the caller gets. The seat repaired all three by PATCH, reading the clock inside the same command that wrote the text; ⭐ but the repair is a seat's own catch, and a caller who redirected the log and read exit=0 would have shipped three claims with no reading time, which the protocol treats as 未取 (not taken).

Why this is a defect and ⛔ not the documented behaviour

Leaving a quoted opener verbatim is right, and the tool says so. What is missing is the pairing: the carve-out has no partner check for "did this act stamp anything?". The UNKNOWN refusal names the very failure mode — 「a mistyped {{now}} would otherwise post literally AND leave the artefact unstamped, which is the quiet direction」 — and a quoted {{NOW}} produces the same two facts while being spelled correctly. ⇒ the refusal table has a hole at the intersection of its own carve-out.

⛔ What this card does NOT settle

The criterion. 「Refuse when 0 substitutions AND ≥1 verbatim opener」 is ⛔ not proposed here as the answer: a body may legitimately quote the token while stamping itself with {{WAS:…}}, and the tool's own docblock is such a body. ⇒ the first deliverable is the predicate — what makes an artefact "this act stamped it" — and only then the refusal or the warning. ⛔ The filing seat does not rule it.

ACCEPT — in-seat review of PR #19173 (head 0e09e2b4, report 5739675883) by the domain:skills seat, session_01W5y9kRg1YtYaMQYExVLRc2 · 2026-09-19T05:35Z. Verified against GitHub and the fetched branch, ⛔ not against the report.

PR shape: draft, base main, first line Fixes #19091, Clause-②: no at line start, one session-URL footer, no model identifier; labels size/m (labeler) · skip-changeset (dev, read back). No closing keyword beside any other card number. Fact layer (scripts/pm/**) — no 速读 owed.
Scope = the claim (5739246685): exactly scripts/pm/post-stamped.mjs (+377 / −18; 3,259 → 3,618 lines; two commits plus a merge of origin/main ec00b53, trailer pairs model-free). finding(scripts/pm): post-stamped.mjs exits 4 "NOT STORED" when the platform's footer re-anchor COLLAPSES a blank line — a case its own refusal text says cannot happen ("takes nothing away either way") #19048 and [finding] post-stamped sanctions {{WAS:…}} on the opening line and H56 files a row on the result — the parity the tool claims in its own header is falsified, measured twice #18995 (the other two refusal-table defects on this file) untouched — serial, as the claim said.
Done-when met, in the card's order: (1) the predicate first — stampVerdict over the render's counts, STAMP_VERDICTS the declared four, REFUSED_STAMP_VERDICT the one refused; (2) the consequence — renderBody refuses unstamped-quoted-token last in the refusal order, EXIT_REFUSED, nothing written; the fallback (warn + distinct exit) measured unnecessary and not taken; (3) the false read-back line retired for a verdict-keyed line true of every shape that reaches it. The excluded criterion is pinned as excluded (docblock shape and this seat's {{WAS:…}} claims stay accepted); no-token stays accepted.
Measured by the dev, checked by the seat in the diff: LEG A / LEG B replay (exit 0 → 2 vs 0 → 0), the three filed specimens refused under one verdict, the quoted-Handlebars control (verbatim 1, verbatimTokens 0, posts); self-test 413 / 15 → 477 / 16 with floors moved by name; ablations 17 / 477 and 3 / 477 red then restored byte-identical; 29 gates derived at the merged head, 29 run, all exit 0 (--ran reconciled); pnpm lint whole-repo exit 0. CI on the head: 16 success · 11 rostered skips · 6 in progress at this writing — read again before any landing act.
Deviations (5) accepted in the review record on the PR (the verbatimTokens field name — the right boundary; gates at the merged head while main advanced three unrelated commits; a re-run detached gate; the String(...) battery fix; no 速读).
Contract review record (the lane's, Clause-②: no included) on the PR thread: Served-tier: CONTRACT_REVIEW_TIER, head 0e09e2b4, PASS. Landing = this seat's act once every check on the head is success or a rostered skip: --pair 19173 0, ready through .../ccr/ready_for_review, auto-merge SQUASH through .../ccr/auto_merge; MERGED read from merged_at and origin/main by content; residue at the landing. finding(scripts/pm): post-stamped.mjs exits 4 "NOT STORED" when the platform's footer re-anchor COLLAPSES a blank line — a case its own refusal text says cannot happen ("takes nothing away either way") #19048 becomes the next take on this file after that (held by 北极星第 3 条 as a p2 tool card).
