+We maintain high test coverage for all core modules (target: 80%+ overall):
+
+- **Crypto**: Target >90% (Argon2id, AES-256-GCM, PBKDF2)
+- **Database**: Target >85% (Vault operations, transactions)
+- **CLI**: Target >80% (All commands, error handling)
+- **TUI**: Target >75% (Acceptable for UI code)

+//! Sensitive data types with automatic memory zeroization
+//!
+//! This module provides wrapper types for sensitive data that automatically

+//!
+//! # Integration Status
+//!
+//! **M1 v0.1**: Type implemented and used in TUI password widget
+//! **M1 v0.2**: Full integration planned (Vault, Record, crypto operations)
+//!
+//! See `docs/plans/2026-01-27-m1-security-and-tui-design.md` for details.
