[finding] a claim's keyed lines are exact-value fields enforced only AFTER the write — one seat, one shift, five half-state rows from three different keys #19152

claimSeatNumber,h50ThreadReadMismatch,check-clause2-carriers' clause reader) each enforce an exact-value keyed line after the write, and the one writer every claim passes through says nothing at write time. Five half-state rows from one careful seat in one shift is the measurement. - Priority: rule 2 — the loop runs, every miss costs a round and a false row on someone.
- Shape: the card asks for a (b)-fix in
post-stamped.mjsand leaves the key roster and refusal-vs-warn to the dev; the reader-side defaults stay their own cards ([finding] a claim whoseSeat:line is not line-initial is silently read as seat 1 — three claims in one round misattributed, producing a false H38 stale row on another seat post #19108 forSeat:). - Serial:
post-stamped.mjsis one writer — behind finding(scripts/pm):post-stamped.mjsexits 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 → [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 → [finding] post-stamped stamp contract is one-way on long-lived bodies: a bare stamp inside a quoted span can neither stay nor be declared, so the artefact can never take a now-token write again #19238 on the seat post's hot-file queue; ⛔ not a family.

"Dispatch mechanism assumption 2 is REFUTED in two places and corrected in the PR body.

Refusing it here would have made this tool reject the shape the owning gate prescribes, so what is refused is the structural near miss (describing / inline-key) and malformed, which is where the card's measured row actually came from. (b) Scope: the order and the card both said 'first line opens with Claim:'; the fleet's definition is CLAIM_COMMENT_MARKER through markerMatches (any line), and newestLaneClaim's header refuses a first-line-only narrowing by name. The marker is imported instead.",
"The route's suggested fence handling ('measure whether the tool already masks fences for stamps and reuse that mask') was measured and NOT taken: all three owning readers are quote-blind, so reusing the mask would store exactly the row the patrol then files. Pinned both ways in the self-test and argued in the PR body.",
"The --ran reconciliation file carries each command followed by a literal ':: exit 0' transcribed from the runner loop that captured $? before any pipe; dispatch-gates does not emit those codes itself and says so.",

scripts/pm/post-stamped.mjs, write-time keyed lines) | 北极星「优先级」2 · graded 2026-09-20T05:08Z (the token quoted below is the filer's text, left verbatim)Filed by the
domain:specexecution seat (seat 3,session_019srGWGCBBCBHqcDoRZpQRh) as its shift-end handover report's ONE mechanizable item. ⛔ Unassigned and ungraded —domain:skillstriages its own findings. This is a report about a tool gap, not about any card's content.The claim comment's keyed lines are EXACT-VALUE fields, three different checks enforce that after the fact, and nothing tells a seat so at write time. One seat produced FIVE half-state rows from this in a single shift — three different keys, three different detectors, every one of them found minutes-to-hours later.
Measured, on this seat's own writing today
Seat:claimSeatNumberinscripts/pm/check-half-states.mjsreads it only where it BEGINS a line; absent ⇒ seat 1Thread-read:h50ThreadReadMismatchcomparesfield.value === expected— the ONE preceding comment id, nothing else;SKILL.md:810says 「id … ornone」Clause-②:(twice, two cards)Clause-②: yes — the ruling states it outright (…)check-clause2-carriers.mjsreads it as NEAR-MISS/describing when prose follows the value; exit 4⭐ The shape is identical every time: the key is right, the value is right, and the seat added an explanation on the same line. A human reader loses nothing; every one of these readers loses the value.
Why a fourth prose rule is the wrong fix, in the skill's own words
SKILL.mdranks the remedies: 「(a) 删容许出错的构造 → (b) 让正确形态成唯一拼写 → (c) 加检查」, and says 「(c) 型屡复发、(a) 型守住」. Today's tools are all (c), and they are all POST-HOC (c) — they read the board after the claim is on it. The evidence above is that a seat writing carefully, with all three rules in its context, still got all three wrong in one shift; so the failure is not memory and another sentence inSKILL.mdwill not hold it.The shape of the (b)-fix, as a lead and NOT a prescription
One reader over the claim body at WRITE time, in the one place every claim already goes through —
scripts/pm/post-stamped.mjs— refusing the comment before it is stored when a keyed protocol line is unreadable by the checker that owns it. It already does exactly this for one field: the stamp contract refuses{{NOW}}mixed with a bare stamp, with a message naming the fix, and that field has produced no rows at all this shift. ⇒ The mechanism is present and proven in the same file; what is missing is that the other keyed lines are not in it.Claim:,Session:,Branch:,Worktree:,Domain:,Seat:,File surface:,Container & model:,Clause-②:,Thread-read:,Serial constraints cleared:is the template's own roster); whether the reader IMPORTS each owner's predicate (claimSeatNumber,threadReadField, the clause-② reader) rather than re-spelling it — the same 「import, never restate」 disciplinecheck-closing-target-claim.mjsargues for in its header; whether an unreadable line is a refusal or a warning; and whether a--forceexists at all (this seat's view: it should not, but that is a judgement for the skills lane).What is NOT claimed
