Notes
- Story critique pour adoption B2C et crédibilité sécurité
- Zero-Knowledge : biométrie ne dérive JAMAIS K_encryption
- Fallback password obligatoire
- Secure Enclave / Keychain iOS requis
- Refactoring T1/T2 : Migration vers react-native-keychain pour portabilité iOS/Android
- T15 tests : 63 tests passent (policyEngine, biometricKeychain, biometric). Tests orchestrator/audit nécessitent corrections mocking.
- T16 tests : 25 tests hooks passent (useBiometricSettings, useAppUnlock). 6 tests intégration pending (singleton mocking).
- T17 tests : 5 scénarios E2E Detox scaffoldés (activation, unlock, fallback 3 échecs, timeout 30min, révocation MDP).
