+
+## fix: Activity spinner stuck spinning forever
+
+The viewer UI activity spinner would spin indefinitely because `isAnySessionProcessing()` queried all pending/processing messages in the database globally — including orphaned messages from dead sessions that no generator would ever process. These orphans caused `isProcessing=true` forever.
+
+### Changes
+
+- Scoped `isAnySessionProcessing()` and `hasPendingMessages()` to only check sessions in the active in-memory Map, so orphaned DB messages no longer affect the spinner
+- Added `terminateSession()` method enforcing a restart-or-terminate invariant — every generator exit must either restart or fully clean up
+- Fixed 3 zombie paths in the `.finally()` handler that previously left sessions alive in memory with no generator running
+- Fixed idle-timeout race condition where fresh messages arriving between idle abort and cleanup could be silently dropped
+- Removed redundant bare `isProcessing: true` broadcast and eliminated double-iteration in `broadcastProcessingStatus()`
+- Replaced inline `require()` with proper accessor via `sessionManager.getPendingMessageStore()`
+- Added 8 regression tests for session termination invariant

-## Bug Fixes

-### Hook Framework JSON Status Output (#655)
-
-Fixed an issue where the worker service startup wasn't producing proper JSON status output for the Claude Code hook framework. This caused hooks to appear stuck or unresponsive during worker initialization.
-
-**Changes:**
-- Added `buildStatusOutput()` function for generating structured JSON status output
-- Worker now outputs JSON with `status`, `message`, and `continue` fields on stdout
-- Proper exit code 0 ensures Windows Terminal compatibility (no tab accumulation)
-- `continue: true` flag ensures Claude Code continues processing after hook execution
-
-**Technical Details:**
-- Extracted status output generation into a pure, testable function
-- Added comprehensive test coverage in `tests/infrastructure/worker-json-status.test.ts`
-- 23 passing tests covering unit, CLI integration, and hook framework compatibility
-
-## Housekeeping
-
-- Removed obsolete error handling baseline file
