Investigate the Safari-only "Lost connection to the AI provider" mid-stream disconnect (Chrome unaffected). Pure instrumentation, no behavior change: the 15s heartbeat interval and all stream callbacks are unchanged. - sse-resilience.ts: startSseHeartbeat() gains an optional onBeat hook fired after each successfully written ping (beat counter). - ai-chat.service.ts: track stream start, first-chunk latency, model-silent gap and heartbeat count; log them on finish/error/abort to classify the drop (idle-gap vs hard wall-clock cap vs slow first chunk). - ai-chat.controller.ts: append elapsed-since-request to the disconnect warn. All blocks tagged "DIAGNOSTIC ... temporary" for easy removal once the Safari failure mode is identified. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
