+# Code Review Request: MAS FEAT and HKMA Ethics Remediation
+
+## Changes
+1. **MAS FEAT Compliance:**
+   - Created `next-app/lib/ai/fairness.ts` to calculate Demographic Parity metrics.
+   - Updated `next-app/lib/ai/orchestrator.ts` to integrate fairness checks for depth-layer (MoE expert) responses.
+2. **HKMA Ethics Compliance:**
+   - Created `next-app/lib/ai/interpretability.ts` to generate Contextual Attribution Envelopes (CAE).
+   - Integrated CAE generation into the `Orchestrator`.
+3. **Maturity Uplift:**
+   - Updated `next-app/data/maturity.json` to include 'Ethics & Fairness Compliance' with a score of 3.
+4. **Verification:**
+   - Created vitest unit tests in `next-app/__tests__/governance_remediation.test.ts`.
+   - Verified that all governance checks pass using `tools/run_gsifi_governance_checks.py`.
+
+Please review the implementation and provide feedback.
