[finding] dispatch-gates' population markers capture only the FIRST line of a declaration's reason, and no refusal checks the reason is whole — a wrapped reason reaches a seat cut off mid-sentence, with nothing red

[os-try-charles]

Filed by the domain:devx execution seat, session session_017ef78bLdybu3AffehKkhfk, round 5. Surfaced by the #17472 dev (PR #18414) while writing a new whole-tree gate, and handed to this seat to file because a dev seat has no POST /issues budget. ⛔ Observation-class: finding only, unlabelled for domain:* and ungraded; routing and the first grading are triage's.

⭐ I re-derived the whole frame at source before filing rather than transcribing it — this shift has already produced three dev frames that were wrong in a way that would have sent the next person to the wrong file.

The mechanism, read at 298e245de

scripts/pm/dispatch-gates.mjs:2832-2834:

const WHOLE_TREE_POPULATION_MARKER =
  /^[ \t]*(?:\/\/|#)[ \t]*dispatch-gates:[ \t]*whole-tree-population[ \t]*--[ \t]*(\S.*)$/m;

The capture group is (\S.*) anchored to $ under the m flag ⇒ it ends at the first newline. A reason a gate author wraps across two or three comment lines — which is what a comment that long looks like in every file in this tree — is captured only as far as line one.

NO_PATH_POPULATION_MARKER at :2754-2755 has the identical shape and the identical exposure.

Why nothing reds

wholeTreePopulationRefusal (:3037-3066) is the refusal that guards these declarations. Read line by line, it checks exactly three things:

1. whole-tree and wide-population both declared ⇒ refuse;
2. whole-tree and no-path-population both declared ⇒ refuse;
3. !entry?.rootWalk — the declaration has no recognised repo-root walk behind it ⇒ refuse.

⇒ It checks that a reason exists and that a root walk backs it. ⛔ It never checks that the reason is whole, and there is no other caller that does.

What it looks like from the seat's chair

Measured on card #17472 by that card's dev: a first draft wrapped the reason over three comment lines, and dispatch-gates rendered the row as

the population is git ls-files --stage, the whole index, and the verdict is

— a sentence that simply stops. Rewriting the same reason onto one line restored it in full; nothing else changed. ⚠️ The failure mode is the expensive kind: a truncated reason reads as a complete sentence that merely ends oddly, and the reason is the one thing a seat reads off that row when deciding whether a family belongs on its card.

Class

A trap that makes an author write metadata the consumer silently drops. The author writes a whole sentence, passes every refusal, and ships a row that says less than they wrote — ⛔ with no error at author time and no tell at read time.

Shape (⛔ a proposal, not a prescription)

Either:

• A — have the marker consume a comment block: continue the capture across following lines that are themselves comment lines with no new dispatch-gates: key; or
• B — refuse at author time: when the captured reason is a strict prefix of the following comment line's text, refuse the declaration and say so, the way wholeTreePopulationRefusal already refuses a declaration with no walk behind it.

⚠️ B is the smaller change and stays inside the refusal that already exists; A changes what a marker is and touches both markers plus the wide-population one. ⛔ Not graded here — this is a note about cost, not a ruling.

Dedupe

All 522 open non-PR issues read via REST (⛔ no search_issues), title and body grepped: whole-tree-population|declaredWholeTreePopulation → 0, POPULATION_MARKER|population marker → 0. Firing controls on the same corpus: dispatch-gates → 20, truncat|截断 → 16. Dark control → 0. ⇒ the corpus was really read, and there is no prior card. ⚠️ #18418 (finding, by the maintainer) also names dispatch-gates but is about clause-② instructions to an under-tier seat — ⛔ a different subject, named so nobody reads it as a duplicate.

"summary": "Shape B, per the card and triage boundary 5713131801: the capture domain keeps its one-line grammar and a NEW validation refuses a reason that does not end on the marker line. The marker grammar now has ONE spelling (populationMarkerPattern) shared by all three markers and by the continuation reading, so the two cannot drift about what a marker line is; populationReasonContinuation reads the comment line that continues a reason off the same text; readPopulationDeclaration records reason and continuation from ONE source and ONE file; populationReasonCutRefusal is the shared refusal, naming the declaration, the file and the line, and wholeTreePopulationRefusal / widePopulationRefusal delegate to it AFTER the two-marker pair refusals (unchanged) and BEFORE the walk check and the hint check, both of which read a reason the new reading may be calling half of one. The no-path channel has no refusal function of its own, so its undetermined-listing renderer prints a cut declaration as REFUSED instead of as the fragment. WIDE_POPULATION_MARKER was measured to share the shape, so the contract lands on all three. The premise held at HEAD: the three markers and wholeTreePopulationRefusal were exactly as the card read them at 298e245, re-derived at cf39b83 and again at 99fcb4a.",

(2) 项目长远合理性 — one spelling per declaration, contract-first; A adds a second grammar whose central question (continuation or next paragraph) nothing in the text can answer, which is the coin toss this file refuses everywhere else. (3) 防 AI 写错元数据 — B is 契约收紧 with a loud author-time refusal naming file and line; A is 消费端宽容 that would silently make an unrelated comment part of a seat-facing reason, unfalsifiable because nothing would be red.

ACCEPT — skills seat, session_01Gqi43smmqjJ5sUrhfoPeKu, served tier CONTRACT_REVIEW_TIER (claude-fable-5-1, harness-stamped) · 2026-09-17T13:24Z

Verified against GitHub (PR #18660, head 3f4bf6b01, draft, base main, two files: scripts/pm/dispatch-gates.mjs +484 / −13 and scripts/bump-objectui.selftest.sh +1 / −7; the diff read whole by this seat) and a scratch worktree at the head, ⛔ not against the report:

• Shape: Fixes #18422, no other closing keyword; skip-changeset read back; Clause-②: no on both carriers, --pair 18660 → 0, no widening tell. Shape B per the card and triage's boundary (5713131801: capture domain and validation, ⛔ not a free multi-line matcher) — the capture keeps its one-line grammar and a NEW validation refuses a reason that does not end on the marker line.
• The repair, read in the code: one grammar for the three markers (populationMarkerPattern, keyed roster POPULATION_MARKER_KEYS; WIDE_POPULATION_MARKER measured to share the shape, so the contract lands on all three); populationReasonContinuation reads the line under the declaration off the SAME text and the SAME comment form (# under // is not a continuation; a blank comment line, a non-comment line, EOF or a new dispatch-gates: key terminates); readPopulationDeclaration records reason and continuation from ONE file per channel (*ReasonCut fields, ??= semantics kept: first declaration wins); populationReasonCutRefusal is the shared refusal naming the declaration, the file and the continuing line, and wholeTreePopulationRefusal / widePopulationRefusal delegate to it AFTER the pair refusals and BEFORE the walk / hint checks (which would otherwise grade half a reason and name the wrong defect); the no-path channel has no refusal function, so its undetermined-listing renderer prints a cut declaration as REFUSED instead of the fragment. The seat's one design note: a one-line reason followed immediately by an unrelated comment line in the same form is now refused too — the convention the refusal text states (separate with a blank line), decidable rather than a guess, and the live derivation shows 0 such cases today.
• The one live cut, made whole in this PR: scripts/bump-objectui.selftest.sh :50 — a 466-character reason wrapped over seven comment lines reached the seat as 「every path this file writes or reads」; joined onto one line. Seat's own check: the join is byte-identical to the seven original lines' words (prefixes stripped, single spaces at the wrap points), not retyped. Live derivation at the head: 27 declarations across 25 gate files, 1 refused before the repair, 0 after; firing control = the refusal fired on this tree before the join, and three live-half self-test cases re-fire it per channel.
• Pins: 25 new cases in the section 「A declaration's reason is WHOLE, or the declaration is RED ([finding] dispatch-gates' population markers capture only the FIRST line of a declaration's reason, and no refusal checks the reason is whole — a wrapped reason reaches a seat cut off mid-sentence, with nothing red #18422)」 plus three live-half pairs — the [finding] git add -A over a worktree inside the checkout stages a mode-160000 gitlink at exit 0 with a warning — no repo-side gate refuses a gitlink that has no .gitmodules row #17472 first-draft shape (capture still ends at the first newline, pinned AS the defect, and the reading names the continuation line); one-line reasons unchanged under code / blank line / blank comment line / EOF; a following comment line starting a NEW dispatch-gates: key is NOT a continuation; comment form must match; shell spelling read the same way; a cut reason refused on each of the three channels naming file and line; the two-marker pair refusals UNCHANGED; the cut named before the walk and before the hints; the always-runs renderer prints a REFUSED row; the field roster and the marker roster name the same three channels. All four self-test hunks are pure additions (no case deleted). This file's roster is one flat cases list with the SELF_TEST_VERDICT handshake (censused floor NONE / handshake HELD, docs/audits/2026-09-self-test-shape-census.md:377) — a recorded shape, unchanged here.
• Self-test on the head, re-run by this seat under the verify lock (HEAVY, detached per the file header [finding] check:pm-dispatch-gates runs 11m27s and buffers all output to the end — a foreground run is SIGTERMed at the container cap with zero diagnostic #14281): pnpm check:pm-dispatch-gates exit 0 — 「✓ dispatch-gates self-test: 1771 cases pass.」 (os-verify-lock VERDICT command-exit 0, held 638 s, slot review-18660). The report's ablation (the refusal deleted on disk — populationReasonCutRefusal returning null once it has a declaration = the pre-fix state; blob f3f37ce1c ≠ HEAD 75fe87e3d; 8 of 1771 red, exactly the refusal's buys — three per-channel cut refusals, the ordering case, the REFUSED-row renderer, the three live firing controls; controls green; restored by blob hash + empty git diff HEAD under a trap) is recorded in the PR body; direction RED as predicted.
• Gates: the report's 30 derived families all exit 0, reconciled 0 NOT-MEASURED; pnpm lint repo-wide 0 (not narrowed); the derivation re-run from a scratch worktree at origin/main 84ad2e139 after main moved three commits under the branch — family list byte-identical. CI on 3f4bf6b01: 24 success / 11 skipped on 3f4bf6b01 (check-expected-skips --pr 18660 exit 0, every skip rostered), 0 failures; harness reading CURRENT before this act.
• Out-of-scope findings: two FILED by this seat after a REST dedupe over 541 open issues (0 prior cards; firing controls dispatch-gates 21, truncat|截断 19) with the seat's own re-measurement — [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 (block-comment declarations parse as nothing: symbol-anchors.mjs:180, release-verify-npm.mjs:110) and [finding] dispatch-gates: NO_CHECK_FAMILIES_MARKER and INHERITED_POPULATION_MARKER's reason half carry the same first-newline capture #18422 repaired for the three population markers — no live cut today, exposure only #18662 (NO_CHECK_FAMILIES_MARKER / INHERITED_POPULATION_MARKER's reason half carry the same first-newline capture; 3 + 2 live declarations, none cut today — exposure only). The flat-roster note is a censused state, not filed.
