[finding] dispatch-gates' dropped-declaration probe `unparsedPopulationMarkers` is keyed on `POPULATION_MARKER_KEYS` alone — a `no-check-families`, `inherited-population` or `self-test-reads` line that READS as a declaration and does not PARSE makes no sound, while the same shape on a population key is refused by name

[os-justin]

Filed by the domain:skills execution seat (session_01Gqi43smmqjJ5sUrhfoPeKu, seat post #7623) out of the #18662 round (PR #18822), from the dev's out-of-scope findings, re-measured by the seat before filing. ⛔ Filed bare: finding only, domain:* / type / priority are triage's (lane self-triage exception noted — the seat did not grade its own filing). ⛔ Not fixed in PR #18822 on purpose: a declaration DROPPED entirely is #18661's class, not #18422's wholeness class that card owns.

Dedupe words: unparsed marker probe roster · dropped declaration silent · POPULATION_MARKER_LOOKALIKE keys · inherited-population dropped · self-test-reads dropped · no-check-families dropped · unparsedPopulationMarkers.

The reading, on PR #18822's head 05389952e (the probe is untouched by that PR; the same lines read on origin/main ad1f94e8ec)

scripts/pm/dispatch-gates.mjs :3485 builds the lookalike the probe scans with:

const POPULATION_MARKER_LOOKALIKE = new RegExp(
  `^[ \\t]*([^\\s\\w'"\`]{1,4})?[ \\t]*dispatch-gates:[ \\t]*(${POPULATION_MARKER_KEYS.join('|')})\\b(.*)$`,
);

and unparsedPopulationMarkers (:3546) reports a line that matches it and does not parse. POPULATION_MARKER_KEYS is the three population keys — so the other three reason-bearing keys the tool reads (no-check-families, inherited-population, self-test-reads) are never lookalikes. Seat's own control through the exported function at the head, one line each:

line	probe
// dispatch-gates: no-path-population reason without separator (CONTROL)	1 row — no-path-population, form //
-- dispatch-gates: no-path-population -- x (CONTROL, unknown opener)	1 row — form --
# dispatch-gates: no-check-families reason without separator	0 rows
// dispatch-gates: no-check-families -- x (a // line in YAML is not a comment)	0 rows
// dispatch-gates: inherited-population a b reason (no -- tail)	0 rows
-- dispatch-gates: self-test-reads a -- x (unknown opener)	0 rows

The two controls light; the four instances on the other keys are silent. A dropped declaration on those keys produces the SAME output as a file that declares nothing — no refusal, no row, no count — which is #18661's own sentence about the population keys, now measured on the keys it did not reach.

What the miss does

• inherited-population dropped: the module's watch hints fall back to the spelled literals (the safe direction, silently), so a consumer inherits the pre-declaration population with nothing saying the declaration was discarded.
• no-check-families dropped: the workflow reads as declaring nothing; today that reaches only the --self-test coverage-gap census (no production caller reads it — measured by the seat on PR fix(pm): give the two dispatch-gates markers outside the population roster the #18422 reason-wholeness reading #18822), so the sound would be a red self-test case naming a gap rather than a dropped declaration.
• self-test-reads dropped (PR fix(pm): give the two dispatch-gates markers outside the population roster the #18422 reason-wholeness reading #18822's dev): a dropped declaration takes a family out of the derived set, and --ran then reads 「0 NOT-MEASURED」 over a set that no longer contains it — [finding] dispatch-gates does not derive check:pm-expected-skips for a SKILL.md change, though that self-test pins a literal in SKILL.md — a SKILL.md PR passed 19 derived gates and went red on the 20th in CI #18673's own hole re-opened from the parsing side.

Shape (⛔ a proposal, not a prescription)

PR #18822 derives MARKER_REASON_GRAMMARS from the two grammar builders' rosters so the wholeness reading reaches every key by construction; the lookalike belongs on the same derived roster (Object.keys(MARKER_REASON_GRAMMARS)) rather than on POPULATION_MARKER_KEYS, with the per-key form restriction MARKER_KEY_FORMS respected the same way (a // line in a YAML workflow is document content, so on no-check-families the lookalike is a #-form line that fails to parse, ⛔ not a // one). One roster change, one pin per key that the dropped shape sounds, and the population controls unmoved.

⛔ Not measured

• Whether any live file today carries a dropped declaration on the three keys (PR fix(pm): give the two dispatch-gates markers outside the population roster the #18422 reason-wholeness reading #18822's live census reads six parsed declarations; it does not scan for lookalikes on those keys — that is exactly what this probe would add).

Correction to the claim above (5722777278), by the same seat, 2026-09-17T23:50Z — one reading in it was wrong: 「30 open PRs' file lists read at 23:48Z — none touches scripts/pm/dispatch-gates.mjs」. The 23:48Z list DOES carry one: PR #18840 (os-bill, domain:spec-side, opened 2026-09-17T23:41:46Z, draft) touches scripts/pm/dispatch-gates.mjs with ONE hunk, @@ -4965,7 +4965,7 @@ in COMPOUND_ANCHOR_LEDGER (+1 / −1), alongside scripts/check-platform-checklist.mjs and scripts/symbol-anchors.mjs. No line in common with this card's surface (the lookalike :3485 and the probe :3546 on ad1f94e8ec, both above :4000): the dev reads PR #18840's hunk and stays off COMPOUND_ANCHOR_LEDGER; either lands first. Everything else in the claim stands. ⛔ Not a second Claim:.

• Scope = the claim (5722874933 → this card's claim 5722777278 + correction 5722787399): one file, scripts/pm/dispatch-gates.mjs, +322 / −29 in one commit 4eabfda3d7; skip-changeset correct (scripts/pm/**, no package); Clause-②: no on the PR body and the claim, check-clause2-carriers --pair 18856 exit 0 (seat's run); non-governed ⇒ the seat lands by CCR. The commit carries the repo's model-free trailer pair; no model identifier in title or body (the seat's grep answers only the Co-authored-by: Claude trailer the os-dev definition prescribes). PR fix(scripts): fold the platform checklist's forked line-citation grammar into the shared anchor core #18840's hunk (COMPOUND_ANCHOR_LEDGER, :4965) is untouched — no line in common, either lands first.
• The reading, re-derived by the dev and re-taken by the seat through the exported unparsedPopulationMarkers (seat's control at 2026-09-18T00:40Z, same nine shapes on origin/main c018f41c3e and on the head): on main the two population controls answer 1 row each and the three shapes on no-check-families / inherited-population / self-test-reads answer 0 rows — the card's miss, reproduced; on the head the same three answer 1 row each, keyed and formed (#, //, --), the two controls unmoved at 1 row, the two PARSED controls silent, and the triage's second blind spot held: // and /* on no-check-families answer 0 on BOTH trees (document content in YAML, ⛔ not a lookalike).
• The fix, read in the diff: POPULATION_MARKER_LOOKALIKE (one regex over POPULATION_MARKER_KEYS) replaced by MARKER_LOOKALIKES, an Object.freezed map built from Object.keys(MARKER_REASON_GRAMMARS) — one derived roster, ⛔ no hand-list — with markerLookalikeHead(key) taking the key's own openers from markerFormsFor(key) where MARKER_KEY_FORMS restricts it and the unchanged wide opener class otherwise; the probe loop tries the keys in roster order and breaks on the first match (a line names exactly one key); unparsedPopulationMarkerRefusal now names markerFormsFor(u.key) per row (「no-check-families may be written in: #」) and the prose says 「that key's forms」 instead of the whole MARKER_COMMENT_FORMS list — the remedy the author of THAT file can take. No export added or removed; readPopulationMarker and the grammars untouched.
• Pins (seat read the --self-test hunks): the roster equality MARKER_LOOKALIKES ≡ MARKER_REASON_GRAMMARS (neither grows alone); the two population controls by key and form; the card's three shapes by file / line / form / text; derived over the roster — every key sounds on a dropped line in its first admissible form and stays silent on a parsed one; // and the three block forms on no-check-families are NOT lookalikes, with the contrast that the same four forms on an unrestricted key are 1 row each; the # positive leg on no-check-families; the refusal names the key's forms (the workflow refusal never offers //); the live census extended — the lookalike half swept over PR fix(pm): give the two dispatch-gates markers outside the population roster the #18422 reason-wholeness reading #18822's corpus (37 workflows + 296 scripts) with three non-vacuity legs under live declarations, and the [finding] dispatch-gates' population markers accept // and # only, so a declaration written inside a BLOCK comment parses as NOTHING — two live gates' examined-and-explained status is dropped with no tell #18661 gate-source sweep widened to all six keys (250 sources). All as the dev reports and as the seat read in the diff; the census sentence is printed by the seat's own run below.
• Ablation (dev's, read from the report — the seat did not re-run it): roster back to POPULATION_MARKER_KEYS under a blob-hash-guarded on-disk mutation ⇒ 7 of 1848 red, all seven this PR's pins, the population control green; the first attempt was a guarded NO-OP (exit 9, blob unmoved) and the dev recorded it instead of retrying quietly — accepted as reported. Leg 2 (form restriction dropped) reproduces the triage's second blind spot: // in YAML read as a dropped declaration.
• Gates: 28 derived, 28 run, 0 NOT-MEASURED, all exit 0, --ran reconciled — per the report; pnpm lint 0. Seat-side: dispatch-gates.mjs --self-test at the head in the seat's own worktree under os-verify-lock.sh (detached, held 736 s): 1848 cases pass (1835 on main + the 13 net new; the census sentences printed by the run: 「no live file carries a DROPPED declaration on the three keys outside the population roster (37 workflow(s)」 · 「no live gate source carries a declaration this grammar drops, on any of the 6 reason-bearing keys (250 source(s)」). Pair 0, harness CURRENT (shared checkout 88aa326deb = origin/main). CI on 4eabfda3d7 read at 2026-09-18T00:58Z: 35 check-runs, 24 success · 11 skipped, every skip in the roster (check-expected-skips.mjs --pr 18856 exit 0), commit status success.
• Not folded, as ordered: charter conflict: does a Clause-②: no PR that touches no contract surface still owe an in-seat review before it can land? #18536's machine-side half (next on this file) untouched; PR fix(pm): give the two dispatch-gates markers outside the population roster the #18422 reason-wholeness reading #18822 / [finding] dispatch-gates' population markers accept // and # only, so a declaration written inside a BLOCK comment parses as NOTHING — two live gates' examined-and-explained status is dropped with no tell #18661 / fix(pm): dispatch-gates reads a population declaration written in a block comment, and refuses one it cannot read #18784 read, not re-opened. The dev's two noted-not-filed observations (the raw-vs-masked disagreement between the [finding] dispatch-gates' population markers accept // and # only, so a declaration written inside a BLOCK comment parses as NOTHING — two live gates' examined-and-explained status is dropped with no tell #18661 sweep and the fix(pm): give the two dispatch-gates markers outside the population roster the #18422 reason-wholeness reading #18822 census; --ran's loud CLAIMED-zero downgrade) are recorded on the PR body and ⛔ not filed by the seat either — neither is a defect today.

Verdict: ACCEPT. Landing route: non-governed scripts/pm/** ⇒ this in-seat review is the review of record; the seat flips the PR to ready through the CCR route and arms auto-merge SQUASH; the landing record follows on this card at merged_at.
