 **Labels:** release-blocker, major, refactor, concurrency
+**Status:** RESOLVED (2026-04-22)

+## Resolution
+
+`run_live_session` was split around two explicit state holders:
+
+- `ActiveCapture` owns the cpal stream handle, audio receiver, and
+  optional runtime-error channel.
+- `LiveLoopState` owns the mutable per-session loop state: resampler,
+  capture buffer, WAV writer, buffer offsets, dropped-audio accounting,
+  in-flight inference task, and duplicate-history buffer.
+
+The top-level worker is now `LiveSessionRuntime`, with focused methods
+for:
+
+- polling in-flight inference
+- draining microphone runtime warnings
+- receiving + resampling an audio chunk
+- dropping pending-buffer overflow
+- flushing the resampler tail when stop is requested
+- dispatching inference when enough audio is buffered
+- draining the last in-flight task
+- finalising the progressive WAV writer
+
+This keeps behaviour intact but removes the "everything in one mutable
+loop" shape that made concurrency review hard. The refactor also made
+RB-01 straightforward enough to land immediately afterward.
