Outbound LLM calls used Node's default global undici agent (default keep-alive pooling, no transport-level reconnect), so a TCP RST on a reused/poisoned keep-alive socket surfaced as "Cannot connect to API: read ECONNRESET" and failed the chat stream and title generation after the AI SDK's own retries were exhausted. Add a dedicated resilient outbound HTTP layer (ai-http.ts): a shared undici RetryAgent over a tuned Agent, exposed as `aiFetch` and injected into every AI provider factory (createOpenAI chat/embeddings/STT, createGoogleGenerativeAI, createOllama) plus the raw JSON STT fetch. The RetryAgent reconnects on connection-level errors (ECONNRESET, ...) on a FRESH socket, opts POST into the retry methods (undici's default list excludes POST), and leaves HTTP-status retries (429/5xx + Retry-After) to the AI SDK to avoid double-retry. - ai-http.ts: shared RetryAgent(Agent) + aiFetch (maxRetries 2, conservative keep-alive, connect timeout, streaming-safe timeouts) - ai.service.ts: inject fetch: aiFetch into every provider factory - ai-http.spec.ts: regression test that aiFetch injects the RetryAgent dispatcher into the underlying fetch Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
