Retargetado para release/v3.8.51 (release/v3.8.50 está congelada — freeze issue #11439). Validado em lote combinado (batch-0824h2, junto de #11435/#11436/#11437) contra o tip de release/v3.8.51: typecheck:core limpo, gates estáticos OK, 127/127 testes focados passando.
Investigação sólida com repro real via container isolado, três causas independentes identificadas e corrigidas com testes de regressão dedicados para cada uma. Obrigado pela contribuição!
⭐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.
* fix(catalog): hash API key in buildCatalogCacheKey so raw credentials never live in the key string (#10313)
* fix(api): yield event loop and bulk-load override tables in catalog build (#9147)
* fix(api): keep bulk hidden-model load inside catalog builder's error boundary
Post-sync-merge fixup for #9147/#10313 against release/v3.8.50:
- Resolve the catalog.ts/catalogCache.ts merge conflicts against several
catalog PRs merged since this branch was cut: keep isModelHiddenBulk()
(this PR's perf fix) alongside isExcludedByProviderConnections() (a
concurrently landed feature), and adopt the already-merged canonical
fingerprintCatalogAuthKey() helper for the cache-key hashing instead of
the now-duplicate inline sha256 computation.
- getHiddenModelsByProvider() was hoisted above buildUnifiedModelsResponseCore's
try/catch, so a read failure there rejected the builder promise instead of
being caught and turned into a sanitized 500 like every other failure in
this function. Combined with the pre-existing promise.finally() dangling
chain in catalogCache.ts's in-flight coalescing, that produced a genuine
unhandled rejection. Move the bulk-load call back inside the try block.
- Align tests/unit/models-catalog-route.test.ts and
tests/unit/10313-catalog-cache-key-hashing.test.ts with the current
implementation (bulk query text/method, truncated fingerprint format).
* perf(api): memoize getConnectionsForProvider in catalog builder
Combining this PR's own bulk hidden-model optimization with the
already-merged isExcludedByProviderConnections() check (from a
different PR) reintroduced an O(connections) scan per model inside
the catalog builder's hot loop, regressing the exact single-stretch
event-loop budget tests/unit/9147-catalog-eventloop-yield.test.ts
enforces (was passing on this PR's own commit before the merge).
Memoizing getConnectionsForProvider() by its (unordered) key-set
substantially reduces the redundant per-model connection scans
(measured ~497ms -> ~210-300ms worst single stretch across repeated
runs), but does NOT fully close the gap to the 150ms budget — still
red. Committing this as a real, safe improvement; flagging for
further investigation (likely getConnectionsForProvider's first-call
cost per provider, or hasEligibleConnectionForModel) before this PR
merges. NOT deciding to relax the test threshold myself.
