Validado numa worktree combinada com a onda de persistência desta leva sobre `release/v3.8.51`: check-file-size e check-changelog-integrity OK, typecheck:core limpo, check-api-typecheck OK (289). Revalidei o head atual mergeado com o tip: typecheck:core limpo e **36/36** entre `db-rate-limit-guard` e as suítes desta PR.
Levantar o cooldown do escopo pai sem deixar os filhos aninhados presos é o miolo — um cooldown órfão em filho é invisível no dashboard e mantém a conexão fora de rota sem explicação.
**Nota de coordenação:** o `setConnectionRateLimitUntil` colidiu com o #12788 (guard contra timestamp não-finito ou já expirado), que mergeei nesta mesma onda. Eu tinha resolvido a integração na minha worktree, mas ao empurrar o push foi rejeitado — você já tinha empurrado `441fd44`, `f853ba5` e `af2ed01` com a integração feita, e a sua ordenação é equivalente à minha. Descartei a minha e mantive a sua; o crédito é seu inteiro. Fica o registro de que push rejeitado não é erro leve: se eu tivesse mergeado sem reler, teria levado a branch errada.
* test(infra): retry recursive temp-dir removal instead of failing a shard on ENOTEMPTY (#11966)
Two shards on release/v3.8.51 went red in one day with the same signature —
"ENOTEMPTY, Directory not empty: /tmp/omniroute-<test>-XXXXXX" — from
combo-same-provider-cascade (Unit Tests fast-path 4/4, on a PR that touches only
.github/) and auth-policy-embeddings-webfetch-7785 (the 20k-test TIA step). Both pass
alone and on re-run: the cleanup races something still writing into the directory
(SQLite WAL/-shm checkpoint, a worker, the backup) and under a loaded hosted runner
the window opens. 1154 test files do their own cleanup with
fs.rmSync(dir, { recursive: true, force: true }); 57 already asked for retries.
One-shot codemod (scripts/ad-hoc/codemod-rm-maxretries.mjs, kept for the record):
every rm / rmSync / rmdirSync option object with `recursive: true` and no
`maxRetries` gains `maxRetries: 5, retryDelay: 100` — Node itself then retries
ENOTEMPTY/EBUSY/EPERM for up to ~0.5 s before giving up. 2243 call sites in 1292
files under tests/, the shared tests/_setup/isolateDataDir.ts exit hook included.
Only the option object changes: no call site, assertion or import is touched.
Validation: prettier and ESLint (with the frozen suppressions) clean on all 1292
files; a random 20-file sample runs green (quota-redis-store hangs identically on
the untouched tree — it needs a Redis on localhost, an environment matter). The
four unit shards on this PR are the full run.
* fix(quality): let check-forgotten-sibling-tests read a 1,000-file diff
The gate shells out to `git diff` through execFileSync with Node's default 1 MB
maxBuffer; the 1,292-file codemod in this PR is the first diff large enough to
overflow it, and the gate died with `spawnSync git ENOBUFS` before comparing
anything. 64 MB is far above any real PR and costs nothing when unused.
