+Implemented in current pass (Phase 2.101 + 2.102 + 2.103 + 2.104):
+1. Tightened company-anchors and business-scope contracts in deep analysis runtime:
+   - `assistantDeepTurnContextRuntimeAdapter.ts`
+   - `assistantDeepTurnAnalysisRuntimeAdapter.ts`
+   - `companyAnchors` now typed as `CompanyAnchorSet | null`;
+   - `businessScopeResolution` now typed as `AssistantBusinessScopeResolution`.
+2. Aligned composition runtime input to accept typed anchors:
+   - `assistantDeepTurnAnalysisRuntimeAdapter.ts`
+   - `runCompositionRuntime` now expects `CompanyAnchorSet | null`.
+3. Preserved behavior:
+   - no runtime logic changes; type alignment only.
+
+Validation:
+1. `npm run build` passed.
+2. Targeted deep analysis pack passed:
+   - `assistantDeepTurnAnalysisRuntimeAdapter.test.ts`
+   - `assistantDeepTurnAnalysisAttemptRuntimeAdapter.test.ts`
+   - `assistantDeepTurnCompositionRuntimeAdapter.test.ts`
+
+Implemented in current pass (Phase 2.105 + 2.106 + 2.107 + 2.108):
+1. Hardened raw retrieval normalization without changing output:
+   - `retrievalResultNormalizer.ts`
+   - added `normalizeRawRetrievalResult(...)` to avoid unsafe raw casting;
+   - added `normalizeNumberRecord(...)` to replace `Record<string, number>` casts for lifecycle distributions.
+2. Preserved behavior:
+   - no logic changes; only safer normalization of raw payload shapes.
+
+Validation:
+1. `npm run build` passed.
+2. Targeted retrieval normalization pack passed:
+   - `retrievalResultEvidenceEnrichment.test.ts`
+   - `retrievalProblemUnitDualPayload.test.ts`
+   - `retrievalLifecycleRuntimeRollout.test.ts`
+   - `retrievalGraphRuntimeDualPayload.test.ts`
+
+Implemented in current pass (Phase 2.109 + 2.110 + 2.111 + 2.112):
+1. Tightened plan-audit and live-route audit typing for deep grounding:
+   - `assistantDeepTurnPlanRuntimeAdapter.ts`
+   - `assistantDeepTurnGroundingRuntimeAdapter.ts`
+   - `assistantDeepTurnAnalysisRuntimeAdapter.ts`
+   - `rbpPlanAudit` / `faPlanAudit` now use `Record<string, unknown> | null` contract;
+   - live route audits now typed to `RbpLiveRouteAuditDebug | null` / `FaLiveRouteAuditDebug | null`;
+   - grounded eligibility guard now typed to `GroundedAnswerEligibilityGuardDebug`.
