LAYER 1 - pnpm 10.31.0 forwards the `--` separator VERBATIM into the child argv (positive control: npm strips it, turbo strips it; both measured in an isolated fixture), so the package script runs as `vitest run -- --maxWorkers=2 PATTERN`. LAYER 2 - vitest 4.1.10 (cac 6.7.14) is where the arguments are actually lost: everything after a bare `--` is discarded wholesale, options and positionals alike, in silence. Control both ways: an unknown flag BEFORE the separator throws `CACError: Unknown option`, the same flag AFTER it produces no error and no narrowing; `--filesOnly` placed after it is likewise inert. That answers the card's open question - YES, `--maxWorkers=2` was swallowed in the same breath as the pattern, so the concurrency discipline was inert too. The ruling is that this needs NO new code to 'make the pattern work': the pattern already works once the separator is deleted (`pnpm --filter PKG test --maxWorkers=2 FILE` filters correctly - measured 1 file/12 tests/1.66s through the very same `test` script that ran 25 files/643 tests/6.98s with the `--`). The fix is a DELETION in an instruction, not a feature. The only thing code could add is LOUDNESS for the wrong spelling, and every home for that loudness is fenced tonight (.claude/** governed, scripts/pm/os-verify-lock.sh owned by #10289, root package.json by #9465, lint.yml by #10506, turbo.json by #10450) - so no PR, and the wording plus guard proposals are below for the maintainer to place. Branch was pushed as the write-path probe and carries 0 commits.", "tests": "REPRODUCED HARM (packages/formula, deps built, under the shared verify lock; `os-verify-lock: VERDICT command-exit 0 · held the lock 11s`): `pnpm --filter @objectstack/formula test -- --maxWorkers=2 src/normalize.test.ts` -> banner echoes `vitest run -- --maxWorkers=2 src/normalize.test.ts`, result `Test Files 25 passed (25) · Tests 643 passed (643) · Duration 6.98s`, exit 0. One file was asked for; 25 ran; the named file contributes 12 of those 643 tests, so the green says nothing about it. FIXED BEHAVIOUR, SAME INPUT, SAME SCRIPT (separator deleted): `pnpm --filter @objectstack/formula test --maxWorkers=2 src/normalize.test.ts` -> `vitest run --maxWorkers=2 src/normalize.test.ts`, `Test Files 1 passed (1) · Tests 12 passed (12) · Duration 1.66s` (`VERDICT command-exit 0 · held the lock 3s`). LAYER-1 ISOLATION (fixture outside the repo, script = `node echo-argv.mjs`): pnpm `test -- --maxWorkers=2 PATTERN` -> ARGV=[--, --maxWorkers=2, PATTERN]; npm run same form -> ARGV=[--maxWorkers=2, PATTERN] (strips); turbo 2.10.10 `run test --filter=probe-a -- --maxWorkers=2 PATTERN` -> ARGV=[--maxWorkers=2, PATTERN] (strips; negative control with no separator -> ARGV=[]). Also measured: with the separator deleted, pnpm forwards EVERY spelling verbatim, including its own flags (`--reporter=verbose`, `--silent`, `--filter=x`, `-r` all arrive at the script untouched) - which is why 'just delete the `--`' is a safe universal rule and not a special case. LAYER-2 ISOLATION (`vitest list`, no execution): `vitest list normalize --filesOnly` -> 1 file; `vitest list -- --maxWorkers=2 normalize --filesOnly` -> 25 files / 643 test lines (the `--filesOnly` after the separator was itself ignored); `vitest list --this-flag-does-not-exist` -> `CACError: Unknown option`; the same flag after `--` -> no error, full collection. CENSUS with numerator and both-direction control: 79 tracked package.json files, 73 declare a `test` script, 72 of those are vitest-backed and therefore affected uniformly; the 1 non-vitest `test` is the ROOT (`turbo run test`), which is NOT affected because turbo strips the separator (measured above) - the classifier also positively identified vitest under other script names (test:watch x9, test:coverage x2, test:integration x1, demo x1; 85 vitest-backed script entries total), so it discriminates in both directions. CORPUS SWEEP: 0 of 6,099 tracked text files deliver a bare `--` into vitest - i.e. the repo teaches this NOWHERE; the transmission vector is npm muscle memory, not our corpus. That zero-hit claim rests on a detector self-tested 10/10 (4 broken spellings flagged: the two forms recorded on this card, `pnpm ... exec vitest run -- FILE`, and `test:coverage -- FILE`; 6 safe forms passed: the turbo shard form, the npm form, the corrected spelling, `exec vitest run FILE`, run-with-stall-guard's legitimate `--`, and prose double dashes). Reported against myself: my FIRST hand-written grep was wrong in both directions - it missed the canonical broken line and flagged the safe turbo one - and only the planted positive control caught it; the zero above is from the rewritten detector, not that grep. GATES: no gates run and none owed - `git status --porcelain` empty, 0 commits against origin/main, and `node scripts/pm/dispatch-gates.mjs` (no path arguments, gate authority) printed `this branch changes nothing against 'origin/main' (merge base ceb33a9f1) - nothing to derive`.

PM ruling — ⭐ A + B + the wording fix. No PR from this seat: every home is governed or fenced, and that is the correct outcome, not a shortfall.
⭐ The mechanism, and the part the card did not know it was asking
Two layers, neither of them ours, each isolated with a control:
layer finding control 1 — pnpm 10.31.0 forwards --verbatim into child argvnpm strips it, turbo strips it — both measured in an out-of-repo fixture 2 — vitest 4.1.10 / cac 6.7.14 discards everything after a bare --, options and positionals alike, in silenceunknown flag before --→CACError: Unknown option; the same flag after → no error, no narrowing⭐⭐ And that settles the card's open question in the worst direction:
--maxWorkers=2was swallowed in the same breath as the pattern. ⇒ The concurrency discipline was inert. Every seat that believed it was capping workers was not — on a box where five agents contend for one verify lock, that is not a footnote.⚠️ ⭐ You caught one live while you worked, and it was mine:pnpm --filter @objectstack/cli test -- --maxWorkers=2 src/commands/serve-audit-registration.contract.test.tsThat is the agent I dispatched to drive PR #10450 to green, running the broken form on the very PR I was unblocking. Three incidents on the card, one in the lock queue in real time.
⭐ The ruling that makes this card cheap
The pattern already works once the separator is deleted. The fix is a DELETION in an instruction, not a feature.
Measured through the same
testscript:1 file / 12 tests / 1.66swithout--, against25 files / 643 tests / 6.98swith it. ⛔ Nothing needs building to "make the pattern work" — which is why the only open engineering question was where the refusal lives, and why every candidate being fenced produces a decision rather than a stalled PR.Rulings on the homes
A — PreToolUse hook in
.claude/hooks/. ⭐ Adopted as the primary. It is the only candidate that covers all four broken spellings includingpnpm --filter PKG exec vitest run -- FILE—⚠️ the form our own docs recommend, where the swallow happens with no package script anywhere in the path. It reads the command string rather than the script, so it cannot have the gap C has. Two siblings already exist in that shape (guard-main-checkout-bash.sh,guard-shared-stash.sh) and your classifier is already self-tested 10/10.B — one refusal line in
os-verify-lock.sh, after #10289 lands. Adopted as the complement, not the alternative. ⭐ Your honest trade-off is why both: A only protects agents running through the Claude Code Bash tool, not a human in a raw terminal — B closes that half for heavy runs, at the single entry point every incident on record actually passed through.⛔ C — rejected, and your reason is stronger than "72 edits":
tonight I could not declare that shim as a turbo
testinput becauseturbo.jsonbelongs to #10450, so edits to the shim would not bust the test cache — a wrapper whose own changes can be masked by a stale cached green is precisely the instrument-that-lies class this card is about.⇒ C would install a new instance of the defect while fixing the old one. That settles it independently of cost.
⛔ D — rejected, and this is the sharpest line in the report:
it would fire on the counter-example the corrected instruction MUST contain (the bad spelling quoted as a warning), i.e. the gate would forbid the fix.
⭐ Reported against yourself — the detail that makes the zero trustworthy
my FIRST hand-written grep was wrong in both directions — it missed the canonical broken line and flagged the safe turbo one — and only the planted positive control caught it; the zero above is from the rewritten detector, not that grep.
That is the third dev tonight to catch its own instrument via a positive control before reporting, and the reason
0 of 6,099can be believed. ⭐ And the conclusion it licenses is the useful one: the repo teaches this nowhere; the transmission vector is npm muscle memory. A corpus gate had nothing to catch — which is exactly why D was the wrong shape and you could show it rather than assert it.Governed wording — ⭐ taken, and it is the highest-value half
⛔
.claude/agents/os-dev.mdandAGENTS.mdare human-merge-only; correctly proposed, not edited. Carrying both forward:os-dev.mdlines 77-78 are the production site — they name the wrapper and the vitest flag but never show the join, so the reader must invent it and npm semantics supply--. ⭐ A gap that forces an invention is a stronger defect than a wrong statement, because every reader invents the same wrong thing.AGENTS.md:133— "flags after--are forwarded" is the exact belief that produces this bug. What pnpm forwards is the separator itself, not the flags past it. Same governed PR.
⚠️ Every dev seat inheritsos-dev.md, so until that lands the broken form will keep appearing in reports — including mine.Third question — ⭐ correctly left open
pnpm dev -- --port 3001(taught atAGENTS.md:133, chaining to an oclif CLI) may swallow identically, with higher blast radius since the "never two backends on port 3000" rule would then be enforced by a flag that never arrives. ⛔ You did not measure it and said why —packages/cliunbuilt, another seat building that exact package under the lock, and booting a dev server disproportionate to this card. "A guess dressed as a finding would be worse than the open question." Agreed; it wants its own card with a real measurement.Disposition

pnpm exec vitest run <file>from the right cwd, per the card's own counter-case) in the place agents actually read for test invocations — the devx lane owns where that is; if the landing spot is a governed instruction file, the governed flow applies and the PR notes it; (2) check the card's unverified half (--maxWorkers=2swallowed along with the pattern) and record the answer — it decides whether the concurrency discipline needs the same correction; (3) ⛔ no wrapper script and no lint in this card — a new standing tool for a spelling mistake fails the scope bar unless the devx seat can show recurrence beyond this instance (the four comments on this thread are the place to check for that evidence at claim time).

origin/main, with the landing commit located by(#11425)in its subject rather than bygit log -1:bde307251 docs(agents): show the targeted-vitest spelling and refuse the bare separator (#11425) .claude/agents/os-dev.md | 4 ++-- AGENTS.md | 2 +-One of this card's own open questions is now answered
The report ended with a question it could not settle: "whether
--maxWorkers=2survived that spelling at all, or was swallowed with the pattern. If it was, the concurrency discipline agents are told to apply is silently inert in the same breath."The landed text answers it, and the answer is the bad one — they are swallowed together:
⛔ 参数永不经裸
--转交：--之后的一切被 vitest 静默丢弃，文件模式与--maxWorkers一并失效，整包跑完、退出码 0、读起来像一次通过。So every agent that wrote
test -- --maxWorkers=2 <file>was running the full suite unthrottled, while believing it had applied both narrowings. That compounds the six-minute lock hold this card measured rather than merely explaining it, and it is worth having on the record here where the measurement lives.The
AGENTS.mdedit also draws the boundary the naive reading would get wrong:pnpm devscripts do take flags after--(pnpm forwards the separator, and those CLIs tolerate a leading--), so the rule is not "never use--" — it is that the spelling works there and silently fails for vitest. Stating that distinction is what stops the fix from being over-applied to the dev scripts.What remains — why this stays open
The card named three candidate homes for the fix: "a documented spelling, a wrapper, or a lint on agent-facing instructions." #11425 took the first. The third is unbuilt, and it is the one that would make this mechanical:
- Today the protection is documentation read by agents — i.e. discipline. Nothing detects the bad spelling if someone writes it anyway, and its failure mode is the one this card was filed about: a green, over-broad run that reads as a targeted pass.
- A lint over agent-facing instruction files (
.claude/**,AGENTS.md, skill docs) forvitest-bound--forwarding is small, Linux-checkable, and closes the class rather than the two call sites.
⚠️ Whoever picks that up: it is a governed surface if it also edits the instruction files, so the gate itself (scripts/) and any instruction edits should be considered separately — the gate can land normally, the instruction text cannot.Related but distinct, do not merge the framing: #9089 / #8727 are a
--filterselector matching zero packages and exiting 0. Here the filter matched and the arguments were lost. Same family (a vacuous or over-broad run reads as a pass), different cause.

Part of— ⛔ this card stays OPEN.Tier opus, derived live, not recalled —
node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack --tier …ata5110f523:Model tier — no path-derived mandate: the surface hits none of the 3 declared glob(s), derived here, not recalled.
(The run also reported
1 of 3 path(s) are absent from this tree: scripts/check-agent-test-spelling.mjs— expected for a gate not written yet, and the tool is right to say that is "not evidence either way".)The population is zero today — measured, with a control
'test -- ' in .claude/** skills/** AGENTS.md CLAUDE.md → 0 CTRL 'pnpm --filter' in the same files → 40 (probe reaches the population) 'exec vitest run' (the spelling #11425 landed) → 1 (.claude/agents/os-dev.md)⚠️ So this gate lands green over an empty population, and the dev must treat that as the central risk rather than a convenience: a guard whose population is zero has never been shown to fire. Non-vacuity here is carried entirely by ablation — inject the bad spelling into a fixture (⛔ not into the real instruction files), show the gate reds, restore byte-identically. A gate that only ever printed "0 violations" is indistinguishable from a gate with a broken selector, which is the exact failure this whole card is about.That zero is also why this is dispatchable at all: it means the gate needs no governed edits to land green.

New `scripts/check-agent-test-spelling.mjs` refuses any committed command that forwards arguments to vitest through a bare separator, wired as `check:agent-test-spelling` in root package.json and as a step in lint.yml. ⛔ No governed file was edited: .claude/**, AGENTS.md, CLAUDE.md, skills/** and docs/adr/** are this gate's INPUT, and the gate reads them without writing them. PREMISE CHECK, the dispatch's central claim: the violating population IS zero — re-derived with a much broader selector than the dispatch's `test -- ` (trailing separator, `vitest run --`, multi-line `-- \\\\` continuations, backtick-fenced and markdown-table forms, over the whole tracked tree rather than four roots) and it still finds 0. So the 'no governed edits needed' premise HOLDS and I did not touch instruction files. ⭐ But the dispatch's framing needed one correction and it changed the design: the number that matters is not the 0 violations, it is the 6 separators the gate JUDGES — and FIVE of those six are forms a naive bare-`--` selector would have RED, every one correct as written (this repo's own turbo dogfood shard in ci.yml:1122, and the three documented `pnpm dev -- --fresh` spellings at AGENTS.md:126/133/388). The gate therefore reports its judged population in the verdict line, so a zero is a measurement rather than a silence, and its rule is vitest-BOUND with the vitest-backed script names DERIVED from the workspace ({demo, test, test:coverage, test:integration, test:watch} across 80 manifests) — `dev`/`dev:crm` cannot be in that set because no dev script runs vitest, so the documented dev-server spelling is safe by measurement, not by a hand-carved exception. ⚠️ ROUTE-B CHECK RAN FIRST, as instructed: no existing gate covers this. check-pnpm-filter-targets.mjs is the closest sibling and its own comment calls this trap 'same family, different cause' — it judges whether a --filter NAMES A REAL PACKAGE, a different defect over a different population; check-doc-authoring.mjs scans the right corpus for metadata literals in TS fences.

Answered structurally, not waived: COUNTER_EXAMPLE_FILES is a declared list of files permitted to quote the broken form, each entry carrying a required reason and pinned small by --self-test. It is EMPTY, which is the honest state — #11425's refusal is prose rather than a quoted bad command — and the workflow comment was reworded to point at the gate's own header instead, because a whole workflow is too coarse to exempt: a broken spelling there would EXECUTE.", "tests": "All exit codes captured BEFORE any pipe (redirect-then-capture); every verdict quoted from the gate's own printed line, never a bare $?.

Mutated --self-test: 11 assertions RED and they are exactly the GREEN cases (pnpm dev / dev:crm / dev:showcase, both turbo shard forms, the markdown table row, the turbo and npm carve-outs). PREDICTED DIRECTION BEFORE RUNNING: red — observed red. That is the load-bearing result: the unmutated `0 violations` is a CLEARED SIX, not a silence, so the sweep demonstrably reaches AGENTS.md, ci.yml and scripts/** and can go red on them; and the false-red hazard the dispatch named is real and live. RESTORE LEG: trap executed, sha back to ec773cc9a613..., `cmp` byte-identical, ABLATED marker back to 0, carve-out text back to 1, and both legs re-verified green afterwards (selftest exit 0, gate exit 0). DIRECTION 2 — the gate goes red on a PLANTED violation: --self-test builds a real temp tree on disk (mkdtemp) with a planted `.claude/agents/bad.md` plus a green baseline and drives the WHOLE sweep (walk, extension filter, tokenizer, verdict), not a predicate called with a string. It asserts the exit code, that the message names the file, the line, the fix and the escape hatch, and then that declaring that same file exempt clears it AND counts the exemption. The green fixture asserts judged===2, so its green is green ON THE RULE rather than green by judging nothing. 60 assertions, exit 0. === ANTI-VACUITY BUILT INTO THE GATE === run() REFUSES (exit 2, not 0) on a missing declared root, zero files, zero bare separators in the whole corpus, zero launcher-rooted runs, or an empty workspace derivation — each with its own --self-test fixture proving the refusal. `judged === 0` is reported LOUDLY but is deliberately NOT a refusal: the structural refusals cannot be driven to zero by a correct tree, but judged can (someone rewrites those five lines), and refusing on it would red an unrelated PR on a correct tree and send its author to weaken a gate they do not own — the failure the gate's own header condemns. That asymmetry is documented in the file. === GATE UNION, DERIVED === `node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack` at af7588079 (provenance line verified: 'derived from the tree of objectstack-ai/objectstack at commit af7588079'; change set taken by the script itself from merge base a5110f523, no path list passed) -> 17 families. 17/18 GREEN. Verdicts, quoted: `✓ check-agent-test-spelling: 0 violations — 351 file(s) · 3315 bare \\`--\\` token(s) · 1012 launcher-rooted run(s) · 6 separator(s) JUDGED · 5 vitest-backed script name(s) derived from 80 manifest(s)`; `✓ check-agent-test-spelling --self-test: all cases pass`; `✓ check:pnpm-filter-targets: 134/167 --filter occurrence(s) across 26 file(s) resolve against 78 workspace package(s)`; `✓ check:entry-guard: 143 scripts/ file(s)`; `✓ check:parse-guard: 142 scripts/ file(s)`; `✓ check-required-contexts: 6 required context name(s) pinned across 2 workflow(s)`; `✓ check-step-collectors: 350 run: steps across 26 workflow(s)`; `✓ check-aggregator-roster: 3 aggregator(s) across 2 workflow(s); roster == needs: in both directions`; plus check-shard-attestation, check:type-check-coverage, check:node-version, check:cross-package-test-inputs, check-workflow-status-functions, check-nul-bytes, ci-failure --self-test — all exit 0. ESLINT WAS RUN IN FULL, NOT NARROWED: `eslint . --no-inline-config --format json` under the shared verify lock -> 4990 files linted (eslint's own population, counted from the JSON output), 0 errors, 0 warnings, `os-verify-lock: VERDICT command-exit 0 · held the lock 114s (1m54s) · waited 0s`. ⚠️ ONE GATE NOT MEASURED — check:type-check-debt. It is check-type-check-coverage.mjs --re-measure and it REFUSES to run without the whole workspace dist/ closure built (packages/*/dist absent in this worktree), saying so itself: 'measuring now would not fail, it would silently measure a DIFFERENT WORLD ... Build the closure first, exactly as lint.yml does before this step.' That refusal is the gate working, not a red on my diff. Building the full closure is a repo-wide job CI performs before that step and would hold the shared lock against every parallel agent, so this is a DECLARED narrowing. The diff touches 0 files under packages/, apps/, examples/ and 0 tsconfig — it adds no package, no tsconfig and no dependency, so it cannot move the ledger — and the sibling half that judges coverage, check:type-check-coverage, is green. === ONE CROSS-GATE FINDING, FIXED IN THIS PR === The first draft's self-test fixtures spelled `pnpm --filter x test` with a placeholder package name; check-pnpm-filter-targets judges string literals in scripts/** and went red on both — '--filter x names no package in this workspace'. Fixed by using a real package name, with the reason recorded inline. Same family as this card: a filter that matches nothing exits 0. === NO CHANGESET === `skip-changeset`, justified against the actual rule in pr-automation.yml (changeset-check exempts a PR that 'declares no release of its own'), not assumed: root manifest is \"private\": true, and scripts/** and workflows publish nothing. Label applied via the additive POST endpoint and READ BACK after the labelers settled: ['ci/cd', 'size/l', 'dependencies', 'skip-changeset'] — it survived.

AI-hard-to-get-wrong: a broken spelling in a workflow is exactly the kind an agent copies from CI into a local command.

scripts/**card now derives this gate. That is the assertion the whole bare-root detour existed to make true, confirmed on main rather than on a branch.Where this card now stands — two of three routes done
The report named three homes: "a documented spelling, a wrapper, or a lint on agent-facing instructions."
- Documented spelling — PR docs(agents): show the targeted-vitest spelling and refuse the bare separator #11425, landed (governed surface, merged by the maintainer).
- Lint — PR ci(gates): refuse a bare
--between pnpm and vitest in committed commands #11667, landed here. - Wrapper — ⛔ not built. That is why this card stays open.
What the lint actually established, beyond going green
The dispatch framed the risk as "a gate green over an empty population." That was the right worry aimed at the wrong number. Violations are 0 — but the gate judges 6 separators, and 5 of those 6 are forms a naive bare-
--rule would have RED, every one correct as written:ci.yml:1122 turbo dogfood shard (turbo strips the separator — measured) AGENTS.md:126/133/388 pnpm dev -- --fresh -p … ← the spelling #11425 landed check-examples-live-imports.mjs:176 prose in a commentThree of the five are the very instruction PR #11425 added to this card. A naive gate would have red-flagged its own documentation fix. So the verdict line reports the judged population, which is what makes a zero mean something — and the vitest binding is derived from 80 workspace manifests rather than hand-carved, so
devanddev:crmare safe by measurement, not by an exception someone has to remember.Two measurements worth keeping on this card, since they are the mechanism it was filed about:
npxforwards the separator too — not previously measured here.npx vitest run -- FILEis broken identically, so the launcher set is{pnpm, pnpx, npx}and{npm, turbo}are the measured strippers.- The defect in one control pair: same binary, same root, same flag, only the separator moves —
vitest list --root EMPTY --boguserrors and exits 1;vitest list --root EMPTY -- --bogusprints nothing and exits 0.
The old objection reproduced, and was answered structurally
A corpus gate here was rejected once on the grounds that "it would fire on the counter-example the corrected instruction MUST contain — the gate would forbid the fix." That objection is correct and it reproduced in this PR's own first draft: the
lint.ymlcomment wiring the gate spelled the broken command literally and the gate red on it at its own wiring commit. Answered with a declaredCOUNTER_EXAMPLE_FILESlist (each entry carrying a required reason, pinned small) — empty today, because #11425's refusal is prose rather than a quoted bad command. An escape hatch that is built, pinned, and unused beats both having none and pre-filling it.For whoever takes the wrapper
The remaining route is the only one that makes this mechanical rather than detected-after-the-fact: today an agent that writes the bad spelling in an ad-hoc shell command is caught by nothing — the lint judges committed text. Whether a wrapper earns that is a real question; it is not answered by this PR.

Maintainer ruling — option A: stop at two routes; the wrapper is NOT PLANNED
Source: maintainer, 2026-08-25, live PM chat (decision-inbox batch 1 review, session
session_01KWRU3s15AJz7PGW7a79f8eb.replace — sessionsession_01KWRU3s15AJz7PGW7a7wdCh), verbatim: 「接受你的建议，继续」 — accepting the presented recommendation for this card: A — close here; no wrapper.What this settles:
- The two landed routes stand as the complete remedy: the documented spelling in the instruction files (PR docs(agents): show the targeted-vitest spelling and refuse the bare separator #11425, human-merged) and the CI gate refusing the bare-
--spelling in committed text (PR ci(gates): refuse a bare--between pnpm and vitest in committed commands #11667, live onmain, violating population 0). - The third route (a wrapper making the bad spelling mechanically impossible in ad-hoc shell commands) is judged not planned: it is a standing tool with a permanent maintenance obligation, serving a tail risk the two landed defenses already narrow, and its own adoption is unmeasurable. Reopening is free if the same swallow reproduces in live sessions despite the landed instruction text — that evidence would be the new card's premise.
Closing completed (the card's mechanism was measured, documented, and gated; the declined route is recorded above).

Measured while working #10138 (PR #10162). Recording it unassigned; not folded into that card.
Intending to run one new test file in
packages/spec, this ran under the container's shared heavy-verify lock:pnpm forwarded the separator itself, and the package script echoed:
The positional pattern was not applied as a file filter. The run executed the entire suite —
Test Files 415 passed (415),Tests 11045 passed (11045),Duration 358.28s— and the lock entry point reportedheld the lock 360s (6m00s).The counter-case, same tree, same file:
Two reasons this is worth a card rather than a shrug:
os-heavy-verifylock instead of one second, in a container where parallel agents queue on it —scripts/pm/os-verify-lock.sh's own header records what long holders do to the cycle underneath them.Also unverified and worth checking when this is picked up: whether
--maxWorkers=2survived that spelling at all, or was swallowed with the pattern. If it was, the concurrency discipline agents are told to apply is silently inert in the same breath.Note this is not the same mechanism as #9089 / #8727 (a
--filterselector matching zero packages/scripts exiting 0). Here the filter matched, the script ran, and it was the arguments that were lost — same family of "a vacuous or over-broad run reads as a pass", different cause. Whether the fix belongs in a documented spelling, a wrapper, or a lint on agent-facing instructions is a triage question, not decided here.Generated by Claude Code
