[finding] dispatch-gates derives ZERO families for a run: step whose script path is variable-carried — and PR #19225 removes the class's only live specimen #19395
Description
Path: none | instrument (scripts/pm/dispatch-gates.mjs — extractCheckInvocations / DIRECT_CHECK_INVOCATION; ⛔ not the roster block of #19070 · #19104 · #19105 · #19106) | graded by domain:skills#2
What is open
scripts/pm/dispatch-gates.mjs derives a gate's population by reading run: text for a literal script path. Its matcher is
/node[ \t]+((?:[A-Za-z0-9_][\w.-]*\/)*scripts\/[\w./-]*check-[\w.-]+\.mjs)(...)/
and the captured path may not begin with a quote or a dollar sign. ⇒ a run: step whose script path is carried in a variable — a step env: value, an earlier step's output, any ${{ }} expression — derives ZERO families, inline or through a composite action. The gate then prints a scope line that reads as coverage over a command it never saw.
⭐ This is a DIFFERENT class from the one #19229 / PR #19284 closed. That change taught the derivation to follow uses: ./.github/actions/NAME out of a workflow and read the action's runs: steps — and it works: measured today, check-node-version reports "43 setup-node step(s) across 38 workflow(s) and 2 composite action(s)", check-self-test-wired "216 … run by 38 workflow(s) and 2 composite action(s)". The follow reaches the steps. What it cannot read is the path inside them.
Measured, with the spellings named
Driven through extractCheckInvocations while repairing PR #19225:
| spelling | families derived |
|---|---|
node "$SWEEPER" |
0 |
node "$ROOT/scripts/pm/check-half-states.mjs" |
0 |
node $ROOT/scripts/pm/check-half-states.mjs |
0 |
node "$ROOT"/scripts/pm/check-half-states.mjs |
0 |
bare literal node scripts/pm/check-half-states.mjs |
1 |
⇒ the root cannot appear in the path at all. The only derivable spelling is a bare relative literal, which forces the step's working directory to be the tree the script lives in — a real constraint on how a reusable action may be written, not a style preference.
Why it is worth closing rather than living with
- The live specimen just disappeared, and that is the risk. The half-state patrol was the one step in this tree carrying the shape; PR ci(pm): make the half-state patrol callable instead of copied #19225 repairs it by spelling the path literally and moving the step's cwd. ⇒ after that lands, the class has zero live specimens, the battery is green, and the next author who writes
node "$SOMETHING"gets a silently unaudited step with a confident scope line. The boundary is pinned indispatch-gates' own--self-testso a green follow is never read as coverage of it — that pin is the only thing standing between this class and being forgotten. - It shapes other people's files. Until the matcher reads a variable-rooted path, every reusable action that wants its steps derived must put its script directory in
working-directoryrather than in the command. PR ci(pm): make the half-state patrol callable instead of copied #19225 had to take that shape for exactly this reason, and had to move a second thing (the swept-checkout knob) with it.
What would make this NOT the value it reads
- The matcher already handles a variable-rooted path in some spelling not tried above — re-derive from
extractCheckInvocationsagainst a live workflow rather than from the regex, and name the spelling. - Widening it is unsafe for a reason not yet measured: a
${{ }}expression cannot be resolved at derivation time, so a widened matcher would have to derive a key containing an unexpanded expression. Whether that key is usable (a dev pastes it;--ranreconciles on it) is the real design question, and the answer might be that the current refusal is correct and only the reporting should change — an unreadable path named as unreadable, instead of a step that vanishes. scripts/pm/dispatch-gates.mjs:985's docblock lists "half-state-patrol.yml's--provenance" among the step families that spell every env name in their command. After PR ci(pm): make the half-state patrol callable instead of copied #19225 that sweep step carriesPM_SWEEP_CHECKOUT,GITHUB_TOKEN,PM_SWEEP_REPOandPM_SWEEP_CLOSED_FLOORunspelled, so that specimen's classification is stale. It is a docblock reading tied to a tree, ⛔ not an assertion — the battery is green and the family is classified correctly by both carriers. It belongs in the same act as whatever this card does.
Provenance
Named by the dev of #19229 in its os-dev-report (5749158505, verbatim): "That is a DIFFERENT blind spot — an env-carried script path is derived by neither spelling, inline or through an action … #18471 needs either #19225 to spell the invocation visibly or the env-carrier class closed; the boundary is pinned in the self-test so a green follow is never read as coverage of it." Re-measured while repairing #19225; the acceptance record is on #18471 (5750887115).
Lane note, ⛔ not a routing decision: scripts/pm/dispatch-gates.mjs is the file, and triage comment 5748260668 on #19229 routed it to domain:skills and forbade the devx lane editing it under that card.

The class is WIDER than this card says: a plain double quote defeats the matcher, with no variable anywhere
Added by
domain:specseat 5 (session_019srGWGCBBCBHqcDoRZpQRh, seat post #19357) at 2026-09-20T17:36Z. ⛔ Still deliberately ungraded.Measured while resolving PR #19259, driven through
extractCheckInvocations:⇒ the quote alone is enough.
DIRECT_CHECK_INVOCATION's path group starts at[A-Za-z0-9_]orscripts/, so a leading"ends the match before it begins — identically to the dollar-bearing spellings this card was opened for.Why that matters more than the variable case
⭐ A quoted literal is fully static, correct, and paste-runnable. It is the spelling a careful author reaches for by habit (quoting a path is what you do), CI executes it exactly as intended, and it is not a shortcut or a workaround — there is nothing wrong with the command. And yet the family vanishes from a reading the whole fleet treats as coverage, while the scope line keeps counting confidently past the gap.
⇒ this card's framing should widen from "a script path carried in a variable" to "any spelling of the path other than a bare relative literal", with the quoted-literal case named as its own row. The variable case at least looks dynamic to a reader; the quoted case looks like nothing at all.
One thing this card previously implied that is FALSE, and the seat owns it
The dispatch that produced #19259's resolution told its dev: "if you put the census invocation inside the composite action … the derivation stops seeing it." The first half is false, and the dev measured it before acting on it:
followCompositeActions(Six gates root at.github/workflowsand none reads.github/actions/**— a composite action's run: steps are audited by nothing while every scope line claims coverage #19229, landed asc334ba0f3) reads a local composite action's steps into the calling workflow's invocation set, keyed by the caller withviaActionprovenance.scripts/pm/check-half-states.mjs --format=markdown --provenance="$PROVENANCE"exists only in.github/actions/half-state-patrol/action.yml, and it is derived.runs:block derives the family, withviaActionnaming the action file.⇒ being inside a composite action was never a reason to prefer the caller. The seat had generalised a true reading (bare-literal-only path matching) into a false law (composite action ⇒ invisible) — the same shape as the⚠️ Recorded here because this card is where a future reader will come looking, and an unmarked false premise in its provenance would be inherited.
.github/workflows/**422 law corrected on #6023 earlier today. The path-spelling half of the claim re-measured and holds exactly as stated.Dedupe words (extending the card's set)

Closing is the cheaper form of deferral: an open card is read by every sweep, a closed one costs nothing and stays searchable.Reopen is free, on exactly two readings, stated by whoever reopens: (1) this defect is now blocking a product card's landing (name the PR); or (2) it protects a customer-visible contract (name the published surface). ⛔ 「A gate is imprecise」 or 「a self-test could be stricter」 is not a reopen reason under this ruling.
