/**
- * SQLite initialization for Capacitor Electron
- * Handles database path setup, plugin initialization, and IPC handlers
+ * SQLite Initialization and Management for TimeSafari Electron
*
- * Database Path Handling:
- * - Uses plugin's default path (/home/matthew/Databases/TimeSafari)
- * - Uses modern plugin conventions (Capacitor 6+ / Plugin 6.x+)
- * - Lets plugin handle SQLite suffix and database naming
+ * This module handles the complete lifecycle of SQLite database initialization,
+ * connection management, and IPC communication in the TimeSafari Electron app.
*
- * @author Matthew Raymer
+ * Key Features:
+ * - Database path management with proper permissions
+ * - Plugin initialization and state verification
+ * - Connection lifecycle management
+ * - PRAGMA configuration for optimal performance
+ * - Migration system integration
+ * - Error handling and recovery
+ * - IPC communication layer
+ *
+ * Database Configuration:
+ * - Uses WAL journal mode for better concurrency
+ * - Configures optimal PRAGMA settings
+ * - Implements connection pooling
+ * - Handles encryption (when enabled)
+ *
+ * State Management:
+ * - Tracks plugin initialization state
+ * - Monitors connection health
+ * - Manages transaction state
+ * - Implements recovery mechanisms
+ *
+ * Error Handling:
+ * - Custom SQLiteError class for detailed error tracking
+ * - Comprehensive error logging
+ * - Automatic recovery attempts
+ * - State verification before operations
+ *
+ * Security:
+ * - Proper file permissions (0o755)
+ * - Write access verification
+ * - Connection state validation
+ * - Transaction safety
+ *
+ * Performance:
+ * - WAL mode for better concurrency
+ * - Optimized PRAGMA settings
+ * - Connection pooling
+ * - Efficient state management
+ *

+/**
+ * SQLite Migration System for TimeSafari
+ *
+ * A robust migration system for managing database schema changes in the TimeSafari
+ * application. Provides versioned migrations with transaction safety, rollback
+ * support, and detailed logging.
+ *
+ * Core Features:
+ * - Versioned migrations with tracking
+ * - Atomic transactions per migration
+ * - Comprehensive error handling
+ * - SQL parsing and validation
+ * - State verification and recovery
+ * - Detailed logging and debugging
+ *
+ * Migration Process:
+ * 1. Version tracking via schema_version table
+ * 2. Transaction-based execution
+ * 3. Automatic rollback on failure
+ * 4. State verification before/after
+ * 5. Detailed error logging
+ *
+ * SQL Processing:
+ * - Handles single-line (--) and multi-line comments
+ * - Validates SQL statements
+ * - Proper statement separation
+ * - SQL injection prevention
+ * - Parameter binding safety
+ *
+ * Transaction Management:
+ * - Single transaction per migration
+ * - Automatic rollback on failure
+ * - State verification
+ * - Deadlock prevention
+ * - Connection isolation
+ *
+ * Error Handling:
+ * - Detailed error reporting
+ * - SQL validation
+ * - Transaction state tracking
+ * - Recovery mechanisms
+ * - Debug logging
+ *
+ * Security:
+ * - SQL injection prevention
+ * - Parameter validation
+ * - Transaction isolation
+ * - State verification
+ * - Error sanitization
+ *
+ * Performance:
+ * - Efficient SQL parsing
+ * - Optimized transactions
+ * - Minimal locking
+ * - Connection pooling
+ * - Statement reuse
+ *
