The custom undici RetryAgent + aiFetch transport added for issue #140 did not actually heal mid-stream provider drops: undici's retry path is a Range-based download-resume that SSE/chat-completions endpoints cannot satisfy, so a reset after the first byte only swapped ECONNRESET for a "server does not support the range header" error. Its only real effect was reconnecting a poisoned keep-alive socket before the first byte, and PR #141 on top of it turned the 60s headers timeout into deterministic ~61s failures (plus CONTENT_LENGTH_MISMATCH from retrying a POST body after a timeout abort). The root cause is the z.ai coding endpoint, not our transport. Remove the whole layer and return all AI provider calls to Node's default global fetch. - delete integrations/ai/ai-http.ts and its spec - ai.service.ts: drop the aiFetch import, the AI_BYPASS_RESILIENT_FETCH diagnostic toggle, and fetch:aiFetch from every chat/embedding/STT factory; raw STT call back to global fetch - ai-chat.controller.ts: drop the stream-timing START log + startedAt - ai-chat.service.ts: drop the first-chunk/FINISHED/ERROR timing logs - .env.example: drop AI_BYPASS_RESILIENT_FETCH Reverts:1af5d34a,7c308728,b7abb7ea,35fc58ea,d6cd2754,6efb8656. Preserved (not part of the rollback): client-disconnect abort, title generation in onFinish, partial-answer persistence, Safari SSE heartbeat. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
