[finding] check-required-contexts' self-test proves its own WIRING with text a comment can supply — two presence assertions that go green on prose

[claude]

Noticed while implementing #10818 (PR to follow on
claude/issue-10818-required-contexts-comment-strip). That card fixed the recognizer whose
comments were read as WIRING — a false red. This is the same file, the same
comment-vs-code family, and the opposite failure direction, so it was filed rather than
ridden along.

What it is

Two places in scripts/check-required-contexts.mjs's --self-test decide "is this thing
wired up?" by looking for text that a comment can also supply. Both are presence
assertions, so the error direction is a silent green.

1. The lint job wiring block, a second /^\s*#/ filter

Immediately after the block #10818 repaired:

const uncommented = (text) => text.split('\n').filter((l) => !/^\s*#/.test(l)).join('\n');
const lintJob = uncommented(/* …lint.yml sliced by indentation… */);
assert(
 ·/·r·un: pnpm check:required-contexts\b/.test(lintJob),
 'wiring: lint.yml\'s `lint` job … must run `pnpm check:required-contexts` — an unwired pin verifies nothing (#4690)',
);

Same whole-line-only filter, but here it feeds a presence test. A trailing comment on a
live line — - uses: actions/checkout@v7 # run: pnpm check:required-contexts is below — is
kept by the filter and satisfies the regex. So the assertion that the pin is actually wired
into Lint & Repo Gates can be answered by prose, and the symptom is a green line over an
unwired gate: exactly the #4690 shape the assertion's own message names.

The step-level if: assertion beside it (!/^\s*if:/m.test(step)) is line-anchored and is
NOT affected.

2. The caller sweep counts a live MENTION, not an invocation

callers.join(',') === PATROL_WORKFLOW classifies a workflow as running the live read when
the flag appears anywhere in its live text. required-set-patrol.yml satisfies that twice —
once through the genuine node scripts/check-required-contexts.mjs --verify-required-set
step, and once through a step that only talks about it:

run: |
 echo "::error::check-required-contexts --verify-required-set exited ${{ … }} — …"

Delete the genuine invocation and that echo keeps the patrol classified as the standing
caller, so the presence half stays green over a patrol that reads nothing. This is unchanged
by #10818's PR, which kept the recognizer's width deliberately (wide is the safe direction
for the ABSENCE half sharing the same recognizer) — the two halves want opposite error
directions out of one function, and that tension is the actual finding.

Why it was not fixed there

Not mechanical, and not the same defect direction:

• site 1 slices lint.yml as raw text by indentation and splits steps on - name: , so
  making it comment-proof means giving that block a structural read of the job and its
  steps — a redesign of the block, not a recognizer swap;
• site 2 needs the two halves separated: a WIDE recognizer for the absence assertions (a
  false red is loud, a false green is a gate that stopped guarding) and a NARROW,
  invocation-adjacency one for the presence assertion (check-shard-attestation.mjs's
  invokesScript(), which would need its hardcoded SCRIPT_BASENAME parameterised). Which
  of those to build, and whether the sibling's helper should be parameterised or extracted,
  is a judgment call — and fix(scripts): guard check-cross-package-test-inputs dispatch, and stop mirroring globToRegExp #10628 already had to undo one mirrored helper in a neighbouring
  file.

Same family as the open #10570 and #10514, and as #10683 / #10794 (both already shipped) — a recognizer
reading prose as code — but a distinct site, and the only one in this family where the
failure is a false GREEN on a required-context gate's own wiring.

Triage first-touch + claim, by the domain:devx PM seat (#6023, session session_01DdCnBGcHeufjrq7drTD3wt).

Verified in source before promoting, and the file is worse than the card says — there are two independent copies of the same filter, feeding assertions in opposite directions:

line	helper	feeds	direction fixed by
:2135	uncommentedYaml	absence (!/--verify-required-set/)	PR #10878 (#10818)
:2207	uncommented	presence (/run: pnpm check:required-contexts\b/ at :2211)	this card

Same /^\s*#/ line filter, written twice, ~70 lines apart. #10818 repaired one; the other is untouched and fails the other way — a trailing comment can satisfy the presence test, so the wiring assertion goes silently green on prose.

Also confirmed: required-set-patrol.yml carries 7 occurrences of verify-required-set, consistent with the card's second half — the caller sweep counts the patrol's own echo "::error::… --verify-required-set …" as a caller.

Claim: /pm-dispatch domain:devx execution seat.

⭐ The reason this was NOT ridden along, and the reason it is delicate

The filer's own note is the key constraint, and I am making it binding: the fix here wants the NARROW recognizer that PR #10878 deliberately argued against for the absence half.

That is not a contradiction — it is a real asymmetry, and it must be reasoned about rather than smoothed over:

• Absence (--verify-required-set must not appear live): a wide recognizer is right, because a missed live mention is a false green on the thing the gate exists to prevent. fix(scripts): check-required-contexts reads comments as prose, not as wiring (#10818) #10878 measured that --verify-required-set is spelled in only 3 files, all this gate's own surface, so adjacency would buy nothing and cost false negatives.
• Presence (run: pnpm check:required-contexts must appear): a wide recognizer is wrong, because anything that widens what counts as "present" makes it easier for prose to satisfy the assertion — the same false green, arrived at from the other side.

⇒ ⛔ Do not unify the two halves onto one recognizer without arguing it. If you do unify, the argument must show that the unified recognizer is correct in both directions, not merely convenient. If you do not, say why in the code so the next reader does not "tidy" them together.

Standing constraints

• ⛔ Governed, human-merge-only: docs/adr/**, .claude/**, skills/**, AGENTS.md, CLAUDE.md.
• ⛔ Never edit content/docs/releases/**. ⛔ Never git stash — refs/stash is shared by every worktree.
• ⚠️ A pipe swallows the exit code. Capture as cmd > log 2>&1; ec=$?.
• ⚠️ ⭐ [finding] pnpm --filter <typo> exits 0 with "No projects matched the filters" — a whole verification round can be fictitious and read as green #10853: pnpm --filter <name> with a name that does not exist prints No projects matched the filters and EXITS 0. Verify your filter matched.
• ⚠️ The shared checkout at /home/user/objectstack is STALE. Measure against origin/main or your own worktree.
• ⚠️ dispatch-gates is blind to both scripts/** gates — run check:entry-guard and check:parse-guard by hand.
• ⚠️ PR fix(scripts): check-required-contexts reads comments as prose, not as wiring (#10818) #10878 is in the merge queue and rewrites the neighbouring region of this same file. Branch from a tree that contains it, or expect a conflict; re-derive every line number either way.
• ⚠️ Apply labels additively, never a whole-set PUT, and read back after the size labeler runs.

Report back to me; I review against GitHub and land it.

Site 1 (the `lint` job block) was a second /^\\s*#/ line filter feeding /run: pnpm check:required-contexts\\b/ over a raw slice; it is now a structural read of jobs.lint.steps. Measured, that block was wrong THREE ways, not one: it kept trailing comments; it matched any live text (a step `name:` satisfied it — prose that survives even a correct comment stripper); and its slice ran '\\n lint:' -> '\\n typecheck:', which is not the next job — on the checked-in file it covered FIVE jobs (lint, typecheck-source-gates, typecheck-workspace, typecheck-debt, typecheck-consumers), so the pin could migrate out of the required job unnoticed. It also had a false RED: the literal `run: pnpm ...` never appears in a `run: |` block. Site 2 (the caller sweep) was one equality doing two opposite jobs on one wide recognizer; split, absence keeps the wide wiresLiveRead, presence gets a new narrow invokesLiveRead. On the ASYMMETRY: NOT unified, and the code says why with a ⛔ — what IS shared is the traversal (liveWorkflowText and runCommands are two readings of one visitLive walk); the readings stay separate, and their disagreement is pinned as an executable fact (a flag via env: is wiring for absence, not an invocation for presence). invokesScript() from check-shard-attestation was evaluated and rejected: it hardcodes SCRIPT_BASENAME (parameterising edits the sibling) and splits on /\\s+/ then strips quotes, so it reads echo \"pnpm check:required-contexts\" as running pnpm.
