⭐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.
Merged — carried forward the PR's own real value (the first 2 commits: ignore ad-hoc BOT_TOKEN/BOT_URL in env-doc-sync, plus the lock-in test). The branch had accumulated 7 more commits chasing the moving release tip across several rebases (each one re-fixing base-reds that had already moved again by the next rebase) — dropped those since they no longer apply to the current tip, and cherry-picked just the 2 with lasting value, preserving your authorship. 14/14 focused tests pass, changelog gate green. Thanks!
* fix(combo): surface context-overflow before compression so oversized requests fail fast with a clear error (#10225)
* fix(combo): make context-overflow deferral target-aware for native Codex passthrough (#10225)
The deferral added by the prior commit checked only operator-named
compression exclusions when deciding whether at least one target "can
compress" — it never accounted for native Codex Responses passthrough
targets, which chatCore.ts unconditionally excludes from compression
(compressionExcluded = nativeCodexPassthrough || ...). Deferring on such
a target's account let an oversized request skip both the combo preflight
AND compression, reaching fetch() uncompressed.
Thread the same request-shape facts chatCore.ts uses
(shouldUseNativeCodexPassthrough: provider/sourceFormat/endpointPath/body/
headers) down into getKnownContextOverflow so the deferral decision can
never drift from chatCore's own — a native-codex-passthrough target now
never counts as "compressible", so a pool made only of such targets keeps
the fast local 400 instead of a wasted round trip.
Adds regression coverage: the pure getKnownContextOverflow target-aware
check, an end-to-end handleComboChat proof that a native-codex-only pool
fails fast with zero dispatches, and two real handleChatCore-path tests
proving compression actually reduces the dispatched body when eligible,
and that a still-too-large-after-compression request is rejected locally
without an upstream call.
