- Fix keyframe 6-tuple → 4-tuple mismatch crashing ExportRunner - Fix ws.broadcast() using wrong event loop from background threads - Fix export counter hardcoded to 1, now auto-increments - Add path traversal protection to file/stream/delete endpoints - Use proper HTTP error codes (was returning 200 for errors) - Add thread safety to WebSocket connection list - Record exports to DB so markers appear - Move WS endpoint to /ws/export (was /api/ws/export) - Prune dead threads from cache job tracker Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
