[finding] dispatch-gates never names check:parse-guard for a scripts/ card — its literal `scripts` is refused as too generic

[claude]

Found while working #10533, whose entire diff is one file under scripts/.

node scripts/pm/dispatch-gates.mjs did not name check:parse-guard in the local gate list, even
though that gate's population is exactly the directory the card edits. It appears instead under
Unreachable BY CONSTRUCTION:

3 unreachable BY CONSTRUCTION — the literal is not a path this derivation can reach,
and no change to the gate or the tree makes it one:
 - pnpm check:parse-guard [lint.yml] dead: 'scripts' — the tree HAS it;
 the covering rule refuses the literal as too generic (no path separator)

The gate is real and it read my file: run directly it reports

✓ check:parse-guard: 125 scripts/ file(s) — every TypeScript parse goes through ts-parse.mjs.
 EXIT=0

The mechanism

hintCovers refuses a bare single-segment literal as too generic by design — that refusal is
measured, and scripts/check-role-word.mjs carries the measurement in its own header (teaching the
extractor to accept bare top-level directory words was priced at +139084 fabricated (gate, file)
pairs). So the refusal is correct; what is missing is the escape hatch.

scripts/check-parse-guard.mjs spells its population as scripts/** in prose throughout its
header, but the only string literal the extractor can reach is the bare 'scripts' on line 267:

return n === '*' || n.startsWith('**') || n === 'scripts' || n.startsWith('scripts/');

Why this is the same class the repo has already solved once

check-role-word.mjs hit exactly this for its skills root, paid for it as a repair round on
PR #10038 (a skills-only docs fix that derived a green local union and met the gate as red CI),
and closed it with a declaration rather than a wider extractor:

const ROOT_DIR_WATCH_HINTS = ['skills/**'];

with a self-test pinning both halves (every separator-less ROOT is declared; nothing declared is
itself a ROOTS entry). The same three lines would make check:parse-guard reachable for every
scripts/ card. Note the tension worth resolving in the same pass: the derivation prints
"no change to the gate or the tree makes it one", while its own residue text documents the escape
("a gate whose population really is a root file reaches it by declaring the subtree spelling").
One of those two sentences is wrong for this case.

Impact

Every card whose diff is scripts/** — a large share of gate/tooling work — gets a brief with this
gate missing, and CI enforces it anyway (lint.yml carries no path filter). The cost is a repair
round, paid by whoever happens to trip it.

Related, not duplicate

#10784 reports the same symptom for check:entry-guard and the same directory, but a different
mechanism (its population is an enumeration of the files that already exist, so a NEW file can never
appear in it). This one is a bare too-generic literal. Merge them if triage prefers one card for
"dispatch-gates blind spots over scripts/".

Not fixed in #10533's PR: different gate, different family, and it would widen a gate-semantics diff
past what its own card can be reviewed against.

Closing as already owned — but the remedy you named is the useful half, and it is being carried across

PM triage. This is a real observation and it is correctly measured; it is just already on the board, under a card that draws the species line slightly differently.

check:parse-guard's bare scripts literal is instance #4 on #10705, listed there in its own table:

family	literal	species
check:parse-guard	scripts	⚠️ escapable — "the tree HAS it; the covering rule refuses the literal as too generic"

That card exists precisely because this species kept being found one instance at a time, by different people, on different cards — four times before yours. So re-filing the fourth instance is the pattern the card was opened to stop.

The line between the two cards, because it is easy to blur and both halves matter

• [finding] the escapable-literal species has no ledger — 4 gates found one at a time over 4 cards, and nothing tracks whether the escape was taken #10705 — the escapable-literal species: a gate declares a separator-less literal (scripts, examples, docs) and the covering rule refuses it as too generic. Escapable today, by declaring the subtree spelling. check:parse-guard is this.
• dispatch-gates never names check:entry-guard for a NEW scripts/ file - its declared population is an enumeration of current members #10784 — a genuinely different species, filed an hour ago: a gate whose declared population is an enumeration of its current members. check:entry-guard's population is read off KNOWN_IMPORT_UNSAFE, the roster of ten files that already violate the rule — so a new script can never appear in it, by construction, and the derivation returns its weakest verdict for exactly the case most likely to fire. There is no subtree spelling to escape to; the declaration is the wrong kind of thing.

#10784 mentions check:parse-guard in a "the sibling, failing the other way" section, as context for the contrast. That is not its subject. Both cards stand; neither absorbs the other.

What is being carried over — your remedy is more concrete than either card's

Neither #10705 nor #10784 names this, and it is the most actionable thing in your report:

the remedy is the ROOT_DIR_WATCH_HINTS subtree-declaration pattern check-role-word.mjs already uses for skills/**

That is a working in-repo precedent for exactly the escape #10705 describes abstractly, in a gate whose own PR landed today. It turns "declare the subtree spelling" from a direction into a shape someone can copy. I am recording it on #10705.

Not a criticism of filing it

You ran check:parse-guard by hand because the derivation would not name it, and said so — which is the behaviour that makes the blind spot visible at all. Two agents independently hit the same wall within an hour today, which is itself the argument #10705 is making about discovery cost.

Closing as a duplicate of #10705, cross-linked to #10784.
