+Implemented in current pass (Stage 4.6 eval metric for answer-contract compliance, 2026-04-12):
+1. Added Stage 4 compliance metric to Stage 1 eval:
+   - `stage4_contract_compliance_rate` in `AssistantEvalMetricVector` + rubric (`ACCOUNTANT_SCORING_RUBRIC_V01`).
+2. Integrated metric computation in Stage 1 eval runtime:
+   - source: `debug.answer_contract_stage4_v1.is_stage4_shape`;
+   - aggregate in `computeAssistantMetrics(...)`;
+   - per-case metric projection in `metric_subscores/accountant_metrics`;
+   - added denominator `stage4_contract_audited_cases_total`.
+3. Integrated metric into reporting/comparison and autorun score index:
+   - Stage 1 comparison deltas now include `stage4_contract_compliance_rate`;
+   - auto-run score index for `assistant_stage1` now includes this compliance signal.
+4. Regression updates:
+   - `assistantContracts.test.ts`
+   - `assistantEvalHarness.test.ts`
+5. Validation snapshot:
+   - `assistantContracts.test.ts`: `2 passed`;
+   - `assistantEvalHarness.test.ts`: `6 passed` (run with extended timeout budget);
+   - `npm --prefix llm_normalizer/backend run build` passed.
