…ng it from the audit (#3347) check-test-wiring.mjs discovered packages with `existsSync`, which answers false for every failure and not only ENOENT. A package whose manifest could not be opened therefore left the audit with no error at all, and the gate printed OK with a smaller count. Measured on a two-package fixture before the change: healthy: OK (2 packages, ...) EXIT=0 packages/beta chmod 000: OK (1 packages, ...) EXIT=0 and the same hole hid the offender the gate exists for. A `gamma` carrying test files and no `test` script went from EXIT=1 naming it to EXIT=0 saying nothing, purely by becoming unreadable. That package's tests never run under `turbo test`, which is the failure this gate is the only thing watching for. The sibling gate check-test-glob-coverage.mjs was hardened against exactly this and grew a local `existsOrThrow`. That refusal is now shared, at scripts/lib/exists-or-throw.mjs, on the same footing as `stripYamlComments` in scripts/lib/server-bin-targets-parse.mjs which both check-test-wiring.mjs and check-server-bin-targets.mjs already import from one place. `fail` is injected so each gate keeps its own prefix and its own FailError; nothing about the refusal is softened to make it shareable. Copying it instead would leave one sentence of load-bearing prose in two files with nothing but habit holding them together. The dotfile skip ships in the same change, because adopting the refusal without it reintroduces the crash PR #3350 just fixed in the two sibling gates: macOS drops a `.DS_Store` FILE into any Finder-opened directory, and statting `.DS_Store/package.json` raises ENOTDIR, which the refusal correctly rejects. Verified by applying the refusal alone and touching packages/.DS_Store in this worktree, which failed the Lint lane. check-test-wiring.mjs also had TWO package-discovery loops, `auditPackages`'s and `readWorkspaceScripts`'s, kept in agreement only by whoever edited one remembering the other. They are one walk with two readers now, so a future hardening cannot land in one and miss the other. Tests, in the pair shape PR #3350 established: a dotfile is ignored, and a non-dotfile ENOTDIR candidate in the SAME tree is still refused. Under the tempting wrong fix (catch ENOTDIR in existsOrThrow and continue) the second one fails, along with two cases in check-test-glob-coverage.test.mjs. Under the other wrong fix (adopt the refusal, skip the dotfile skip) the first one fails. scripts/lib/exists-or-throw.test.mjs additionally pins the branch neither gate can reach: a `fail` that returns must still not yield a false. Counts on the real repo are unchanged: 48 packages before and after.
`node scripts/typecheck-tests.mjs` run bare with cwd = the repo root treated the repository as a package. parseCliMode accepts zero arguments as `package` mode, so it fell into `checkOnePackage(process.cwd())` and wrote a 1,520-line /tsconfig.tests.json naming 1,505 test files, then handed the lot to one tsc invocation. It printed nothing at all while doing so. That is the #2664 misuse this script's own header documents, and parseCliMode already refuses the ARGUMENT form of it: `node scripts/typecheck-tests.mjs packages/clash` from the root used to ignore its argument and fall through to the same cwd branch. The cwd form is the same substitution with the argument left off, and it was still open. PR #3363 added /tsconfig.tests.json to .gitignore, which was right for diff noise and which also removed the last visible symptom. An untracked file someone would eventually notice became a silent run whose only output was an OK line naming the repo directory as if it were a package. A guard is what is left. `repoRootRefusal` is the sibling of the guard parseCliMode already has, and it names the three real ways to run this so the message says what the caller probably meant. Paths are compared through realpath as well as resolve, for the reason scripts/check-changesets.mjs already compares `rootReal`: cwd reports the realpath while REPO_ROOT comes from this file's own URL, so a symlinked checkout spells one directory two ways. Before: a 1,520-line file at the repo root, no output, tsc running for minutes. After: exit 2, the refusal, and nothing written. Unit tests pin the path arithmetic including the symlink spelling; one spawned case pins that checkOnePackage actually consults the guard. That last one is the only test that fails under a guard placed on the argument form alone, which is the fix this issue invites. Verified by removing the checkOnePackage call: 36 of 37 cases still passed and only the spawned one caught it, reporting that the repository had been treated as a package. `--all`, `--audit` and the real per-package run are unaffected: audit reports 1,502 files across 47 packages as before, and packages/embed-protocol still checks OK from its own directory.
…contains /simplify, four angles. Two agents independently found the same structural miss: extracting existsOrThrow shared 15 lines and left 32 duplicated, because listPackages then became byte-identical in check-test-wiring and check-test-glob-coverage - differing only in a constant's name, 'utf-8' vs 'utf8', and the wording of a 12-line comment that was itself duplicated. The first commit's own docstring argues that two walks kept in agreement by whoever edited one remembering the other "is not a property, it is a habit, and #3347 is what it costs". That argument is exactly as true across two files. scripts/lib/list-workspace-packages.mjs now owns the walk and the parents constant. 58 lines out of one gate, 32 out of the other. It also states the invariant the altitude pass distilled, which is narrower and more useful than "be loud everywhere": unreadable must never shrink a population a gate reports a count of. That explains why a refusal and a calibrated floor are alternatives rather than a hierarchy, and why verify-npm-publish and rust-major-offset are right to warn-and-floor instead. NOT migrated, and the reason is load-bearing: scripts/docs/check-package-readmes.mjs keeps its own copy. Two reviewers ranked folding it in as the top finding, both citing that the repo already documents it as a duplicate. Neither checked why. Its regression harness copyFileSync's THAT ONE FILE into a synthetic tree, so it must stay import-free beyond node builtins; migrating it turned all 9 of its tests red while the gate still passed against the real repo, because the failure only exists in the synthetic tree where ../lib/ does not. The constraint is now written in the file. Three claims of mine that were false: - "A PROJECTION of listPackages, not a second walk" was true of the source and false of the run: it is called once per reader, so there are still two walks. Measured at 0.96 ms of a 100 ms gate, which is why it stays two. - "#3350 fixed exactly this in two sibling gates" - it fixed three. - samePath's realpath half was justified by a symlinked-checkout divergence. Measured on four invocations - through a symlink, with --preserve-symlinks, invoking through the link, and both - and path.resolve matched every time, because getcwd(3) returns the resolved path and Node's ESM loader realpaths the module URL. Kept as defence for unmeasured platforms, but it no longer claims to catch a case that occurs here. check-ci-path-coverage then caught a consequence I had not thought about: moving the apps/ walk into the lib made the allowlist row exempting check-test-wiring from apps/landing stale. Deleted, per that gate's own advice that a stale exemption hides the next hole. 36 reasoned exemptions now, down from 37. 1056 script tests pass, lint clean, all four gates green on the real repo.
…het still sees it /code-review caught that the previous commit silently shrank CI path coverage, and that I then deleted the evidence instead of the gap. deriveInputs (scripts/lib/ci-path-coverage.mjs) reads only a gate's OWN source text and does not follow imports. Moving the ['packages','apps'] literal into the shared walk therefore removed those paths from the census. Measured with the repo's own deriveInputs across both revisions: MAIN check-test-wiring.mjs: .github apps node_modules package.json packages scripts HEAD check-test-wiring.mjs: .github node_modules package.json scripts MAIN check-test-glob-coverage.mjs: apps node_modules package.json packages HEAD check-test-glob-coverage.mjs: node_modules The allowlist row I deleted last commit had not gone stale because the coverage became unnecessary. It went stale because the coverage DISAPPEARED. Deleting it removed the symptom and kept the hole: drop apps/landing from the node-tests path filter and check-test-wiring would stop running on apps/landing changes, with check-ci-path-coverage - whose entire purpose is "a gate may not read a path that cannot trigger it" - saying nothing. Each gate keeps its own PACKAGE_PARENTS literal now, with a comment saying why it must not be hoisted. The WALK stays shared, which was the point. The allowlist is restored byte-identical to main: git diff reports 0 lines. The census reads 288 derived input paths against main's 287, so coverage is slightly wider than before rather than narrower. Also from that review: - existsOrThrow was imported and unused in both gates after the hoist, since both now reach it through the walk. Nothing in the repo would have caught it: check-unused-locals only scans workspace packages with a tsconfig, and no lint config covers scripts/*.mjs. - In exists-or-throw.mjs the import sat BETWEEN the JSDoc block and the function it documents, so the @PARAM annotations attached to nothing. - check-package-readmes.mjs pointed at "check-test-glob-coverage.mjs's listPackages()", which the previous commit deleted. That pointer sits directly under the paragraph explaining why this file deliberately does NOT share the lib, so a reader following it landed on nothing. 1056 script tests, all four gates, check-ci-path-coverage and lint: green.

Closes #3347 and #3362. Two gates that could not say no.
#3347 — an unreadable package left the audit silently
check-test-wiring.mjsdiscovered packages withexistsSync(pkgJsonPath), which returns false for every failure, not just ENOENT. So a package whose manifest could not be read was dropped from the audit and the gate reported OK.That gate is what fails when a package has test files but no
testscript, soturbo testskips it. Which means: a package whose tests never run read exactly like a healthy package.Measured on a synthetic tree, and this is the damage rather than the mechanism:
Becoming unreadable was all it took to turn the finding off.
The refusal is now shared at
scripts/lib/exists-or-throw.mjs, withfailinjected so each gate keeps its own prefix and error type.check-test-glob-coverage.mjsmoved onto it too.#3362 — the repository treated as a package

That is the #2664 misuse the script's own header documents, andparseCliModealready refused the argument form of it but not the cwd form.PR #3363 had just added that path to
.gitignore— correct for diff-noise reasons, but it removed the last visible symptom. Now it refuses, naming--audit/--all/cd <package>.The walk is shared too, not just the refusal
