//! Property-based tests proving error sanitization invariants.
//!
//! These tests use proptest! to verify that FraiseQL error sanitization
//! never leaks secrets, always maintains consistent structure, and prevents
//! `DoS` via error messages.
//!
//! # Sanitization Invariants
//!
//! All tests verify:
//! 1. **No Secrets** - Passwords, tokens, DB URLs never appear in user messages
//! 2. **No SQL Keywords** - Dangerous SQL keywords hidden from production
//! 3. **Bounded Size** - Messages truncated to prevent `DoS`
//! 4. **Consistent Structure** - All errors follow same format
//! 5. **Deterministic Hash** - Same error always produces same hash
//! 6. **No File Paths** - System paths redacted from user messages
//! 7. **No Connection Details** - Database URLs, hosts, ports hidden
//! 8. **No Stack Traces** - Implementation details redacted
//!
//! # Example Attack Patterns
//!
//! These tests protect against:
//! - Error messages revealing database schema: `error: Column 'password_hash' doesn't exist`
//! - Connection string leakage: `error: postgresql://user:pass@host/db connection failed`
//! - File system disclosure: `error: /root/.ssh/id_rsa permission denied`
//! - SQL injection signatures: `error: unexpected token DROP`
