- Added optional FetchImpl fields to compaction, proxy, AI, coding-agent, and mnemopi options.
- Threaded injected fetch implementations through OAuth, discovery, and search/LLM request flows.
- Removed exported hookFetch utility and its package entrypoint from utils.
- Replaced global-fetch test monkeypatching with per-test FetchImpl mocks across test suites.
Reviewer noted that an unconditional ExaProvider.isAvailable steered the auto chain into the public MCP fallback before any later-configured provider could run. Restored the credential-gated isAvailable, then split out isExplicitlyAvailable so resolveProviderChain still routes an explicit Exa selection through MCP without affecting other providers.\n\nRefs #1860
Restored Exa's unauthenticated MCP fallback when neither auth storage nor EXA_API_KEY provides credentials. Preserved API-key search ordering and bounded the MCP request with the web-search hard timeout. Updated provider copy and regression coverage for the no-key path.\n\nFixes #1860
ExaProvider.isAvailable() and searchExa() now consult AuthStorage so Exa credentials configured through the broker/credential store work alongside EXA_API_KEY, matching the other API-key search providers.

Adds a shared classifyProviderHttpError helper that maps the well-known
failure shapes (status 401/402/403 and bodies matching credits / quota
/ insufficient) into compact SearchProviderError messages so the
orchestrator advances to the next provider instead of bailing.
Wired into every HTTP-talking provider (codex, exa, gemini, anthropic,
brave, jina, kimi, perplexity, searxng, synthetic, tavily, zai) and the
two wrapped-error providers (kagi via KagiApiError, parallel via
ParallelApiError). The orchestrator now collects per-provider failures
and emits a joined summary ("exa: 403 forbidden; codex: credits
exhausted; ...") when the whole chain fails.
Test updates: web-search-{exa,tavily,kagi} message expectations now
assert the compact "<id>: <status> <reason>" form.
- Replaced vi.spyOn fetch mocking pattern with hookFetch utility across 5 test files.
- Migrated fetch mocks to use resource management with 'using' keyword for automatic cleanup.
- Removed @ts-expect-error comments related to fetch.preconnect type issues.
- Updated ts-hook-fetch rule documentation with expanded patterns and clearer lifecycle guidance.
Request contents.summary from Exa /search API and combine up to
3 non-empty summaries into SearchResponse.answer, replacing the
previous 'No answer text returned' output.
Changes:
- Add contents.summary to every Exa search request body
- Add summary field to ExaSearchResult interface
- Export synthesizeAnswer() to build combined answer from summaries
- Export buildExaRequestBody() for testability
- Export normalizeSearchType() (was private)
- Prefer summary over text/highlights for snippet field (falsy check)
- Only synthesize answer from results that have a URL (mirrors sources filter)
Tests: 37 new tests covering normalizeSearchType, buildExaRequestBody,
synthesizeAnswer (pure unit tests) and searchExa (mocked fetch)
