* 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.
⭐5 — Provider x-search de primeira classe (SuperGrok/xAI x_search) em POST /v1/search e MCP omniroute_x_search. Fallback de credenciais xai-oauth→xao→xai; distinto de web search e do X Developer MCP.
Reconciliado com o release tip (que já incluía #10981 "skip catalog-default SearXNG" deste mesmo lote): merge trouxe 5 conflitos reais de contagem gerada (llm.txt/README.md/AGENTS.md/PROVIDER_REFERENCE.md/SVGs/46 mirrors i18n, todos verificados como bump puro 347→348, sem perda de conteúdo do HEAD) + 1 conflito real de mergeable=CONFLICTING.
Durante a validação, os 3 testes novos de SearXNG expuseram um bug real de interação com #10981: `isUnconfiguredLoopbackSearchProvider()` checava o baseUrl ESTÁTICO do catálogo em vez do baseUrl efetivo (após override de `provider_options.baseUrl` ou `providerSpecificData.baseUrl` da conexão), então QUALQUER request a searxng-search — mesmo com override customizado — era rejeitado como se fosse o default não-configurado. Corrigido em `open-sse/handlers/search.ts` (resolve o baseUrl efetivo via `resolveSearchBaseUrl()` antes do skip-check, tanto para o provider primário quanto o alternate). Um teste do próprio #10988 que assumia o comportamento pré-#10981 (default localhost:8888 sempre atendido) foi atualizado para refletir o comportamento já mesclado e intencional (503 quando não configurado).
Validação completa: typecheck limpo, 70/70 testes unit (search-route/search-registry/x-search-provider/searxng-loopback-default), 24/24 vitest MCP, 14/14 integration (search-providers-catalog), lint limpo nos arquivos tocados, docs-counts-sync OK (2 drifts soft pré-existentes, não relacionados), gates estáticos (file-size/complexity/cognitive/dead-code/changelog) todos OK.
