+### Stage 3 Exit Audit (2026-04-11)
+1. Functional gate:
+   - `npm --prefix llm_normalizer/backend run build` passed.
+2. Regression gate:
+   - Stage 3 focused suite passed: `9 files / 356 tests`.
+   - (`addressQueryRuntimeM23`, `assistantWave17RunRegression20260411`, `assistantWave18ManualCommentsRegression`,
+      `assistantLivingRouter`, `assistantLivingChatMode`, `assistantSoftPolicyReply`,
+      `assistantBoundaryFallbackReply`, `assistantAnswerPolicyV11`, `assistantSemanticExtractionContract`).
+3. Runtime stability gate:
+   - address lane includes protective fallback for legacy MCP schema error (`SubcontoDt1`) and avoids hard execution drop for debt-lifecycle receivables prompts.
+4. Manual smoke:
+   - reviewer confirmed fixed questions on latest spot checks; domain breadth expansion is tracked separately and is not a Stage 3 blocker.
+5. Full backend suite note (non-blocking for Stage 4 kickoff):
+   - `npm --prefix llm_normalizer/backend run test` reports red integration groups with `5000ms` timeout budget (`assistantEvalHarness`, `assistantP0EvalHarness`, `assistantStage2EvalHarness`, `assistantStage3LifecycleAcceptanceProbe`, part of `assistantEndpoint`/`assistantBroadGuard`).
+   - one user-facing policy assertion currently diverges when live MCP returns aborted fetch (`This operation was aborted`), producing execution-error soft reply instead of expected clarification template.
+   - these failures are tracked as stability/infra debt and do not block Stage 4 answer-layer kickoff for already green Stage 3 focused contract pack.

+Status: Completed (Stage 3 gate approved; domain expansion moved to Stage 5 backlog)
