From 7190c8429e78ee5ab3f13eb3756dcaa23a18c398 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 10 Jul 2026 20:44:54 +0000 Subject: [PATCH 1/7] fix: stop aborting live answer streams at a flat 60s timeout Live answer generation failed with 'Answer generation timed out. Please try again.' whenever the fast answer failed a quality gate and escalated to the strong model: the pipeline (fast <=30s + strong <=30s + optional strong quality repair <=30s, plus retrieval) legitimately exceeds 60s, but the dashboard aborted every answer request at a flat 60s wall clock even while tokens were still streaming. - Replace the flat timer with a stall watchdog: the 60s window now resets on every received stream chunk, so a slow-but-live generation is never aborted mid-stream; a 180s absolute ceiling still bounds runaway requests. Document searches keep the old flat 60s behavior. - Emit SSE comment heartbeats every 15s from /api/answer/stream so silent generation windows (strong-route reasoning before the first output token) stay visibly alive to proxies and the stall detector. - Guard controller.close() against an already-cancelled stream.
