+Implemented in current pass (Phase 2.26):
+1. Extracted living-chat finalization/response tail from `assistantService` into dedicated runtime adapter:
+   - `assistantLivingChatTurnFinalizeRuntimeAdapter.ts`
+   - introduced:
+     - `finalizeAssistantLivingChatTurn(...)`
+2. Centralized living-chat finalization runtime sequence (behavior-preserving):
+   - assistant item creation for chat lane;
+   - structured `assistant_message_chat` processed-event payload build;
+   - turn commit/persist/log via shared commit runtime adapter;
+   - API success response assembly from committed conversation state.
+3. Rewired `assistantService` `tryHandleLivingChat(...)` finalize path to consume adapter output (behavior-preserving).
+4. Added focused unit tests:
+   - `assistantLivingChatTurnFinalizeRuntimeAdapter.test.ts`
+
+Validation:
+1. `npm run build` passed.
+2. Targeted living/address/deep finalize pack passed:
+   - `assistantLivingChatTurnFinalizeRuntimeAdapter.test.ts`

+   - `assistantDeepTurnFinalizeRuntimeAdapter.test.ts`
+   - `assistantLivingChatMode.test.ts`

+3. Additional safety regressions passed:
