A comprehensive stall detection system has been added that logs timing information for:
- Stream idle partials:
[Stall] stream_idle_partial lastChunkAgeMs=... - Classifier requests: start, progress, and finish with timing and outcome
- Tool dispatch: start, end, and post-error with tool name and permission decision timing
- Agent completion events
This helps diagnose performance bottlenecks and stuck sessions.
Evidence
Stall detection logs (search for "[Stall]"), with fields like promptTokensEst= and permissionDecisionMs=.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
