-/**
- * TimeSafari Database Migration Definitions
- * 
- * This module defines all database schema migrations for the TimeSafari application.
- * Each migration represents a specific version of the database schema and contains
- * the SQL statements needed to upgrade from the previous version.
- * 
- * ## Migration Philosophy
- * 
- * TimeSafari follows a structured approach to database migrations:
- * 
- * 1. **Sequential Numbering**: Migrations are numbered sequentially (001, 002, etc.)
- * 2. **Descriptive Names**: Each migration has a clear, descriptive name
- * 3. **Single Purpose**: Each migration focuses on one logical schema change
- * 4. **Forward-Only**: Migrations are designed to move the schema forward
- * 5. **Idempotent Design**: The migration system handles re-runs gracefully
- * 
- * ## Migration Structure
- * 
- * Each migration follows this pattern:
- * ```typescript
- * {
- *   name: "XXX_descriptive_name",
- *   sql: "SQL statements to execute"
- * }
- * ```
- * 
- * ## Database Architecture
- * 
- * TimeSafari uses SQLite for local data storage with the following core tables:
- * 
- * - **accounts**: User identity and cryptographic keys
- * - **secret**: Encrypted application secrets
- * - **settings**: Application configuration and preferences
- * - **contacts**: User's contact network and trust relationships
- * - **logs**: Application event logging and debugging
- * - **temp**: Temporary data storage for operations
- * 
- * ## Privacy and Security
- * 
- * The database schema is designed with privacy-first principles:
- * - User identifiers (DIDs) are kept separate from personal data
- * - Cryptographic keys are stored securely
- * - Contact visibility is user-controlled
- * - All sensitive data can be encrypted at rest
- * 
- * ## Usage
- * 
- * This file is automatically loaded during application startup. The migrations
- * are registered with the migration service and applied as needed based on the
- * current database state.

+// etc. At the beginning, we'll prompt for a password, then we'll prompt for a
+// PWA so it's not in a browser... and then we hope to be integrated with a
+// real wallet or something else more secure.

- * Migration 001: Initial Database Schema
+ * @param sqlExec - A function that executes a SQL statement and returns the result
- * 
+ * @param extractMigrationNames - A function that extracts the names (string array) from "select name from migrations"
- * This migration creates the foundational database schema for TimeSafari.
- * It establishes the core tables needed for user identity management,
- * contact networks, application settings, and operational logging.
- * 
- * ## Tables Created:
- * 
- * ### accounts
- * Stores user identities and cryptographic key pairs. Each account represents
- * a unique user identity with associated cryptographic capabilities.
- * 
- * - `id`: Primary key for internal references
- * - `did`: Decentralized Identifier (unique across the network)
- * - `privateKeyHex`: Private key for signing and encryption (hex-encoded)
- * - `publicKeyHex`: Public key for verification and encryption (hex-encoded)
- * - `derivationPath`: BIP44 derivation path for hierarchical key generation
- * - `mnemonic`: BIP39 mnemonic phrase for key recovery
- * 
- * ### secret
- * Stores encrypted application secrets and sensitive configuration data.
- * This table contains cryptographic material needed for secure operations.
- * 
- * - `id`: Primary key (always 1 for singleton pattern)
- * - `hex`: Encrypted secret data in hexadecimal format
- * 
- * ### settings
- * Application-wide configuration and user preferences. This table stores
- * both system settings and user-customizable preferences.
- * 
- * - `name`: Setting name/key (unique identifier)
- * - `value`: Setting value (JSON-serializable data)
- * 
- * ### contacts
- * User's contact network and trust relationships. This table manages the
- * social graph and trust network that enables TimeSafari's collaborative features.
- * 
- * - `did`: Contact's Decentralized Identifier (primary key)
- * - `name`: Display name for the contact
- * - `publicKeyHex`: Contact's public key for verification
- * - `endorserApiServer`: API server URL for this contact's endorsements
- * - `registered`: Timestamp when contact was first added
- * - `lastViewedClaimId`: Last claim/activity viewed from this contact
- * - `seenWelcomeScreen`: Whether contact has completed onboarding
- * 
- * ### logs
- * Application event logging for debugging and audit trails. This table
- * captures important application events for troubleshooting and monitoring.
- * 
- * - `id`: Auto-incrementing log entry ID
- * - `message`: Log message content
- * - `level`: Log level (error, warn, info, debug)
- * - `timestamp`: When the log entry was created
- * - `context`: Additional context data (JSON format)
- * 
- * ### temp
- * Temporary data storage for multi-step operations. This table provides
- * transient storage for operations that span multiple user interactions.
- * 
- * - `id`: Unique identifier for the temporary data
- * - `data`: JSON-serialized temporary data
- * - `created`: Timestamp when data was stored
- * - `expires`: Optional expiration timestamp
- * 
- * ## Initial Data
- * 
- * The migration also populates initial configuration:
- * - Default endorser API server URL
- * - Application database secret
- * - Welcome screen tracking

-/**
- * Migration 002: Add Content Visibility Control to Contacts
- * 
- * This migration enhances the contacts table with privacy controls, allowing
- * users to manage what content they want to see from each contact. This supports
- * TimeSafari's privacy-first approach by giving users granular control over
- * their information exposure.
- * 
- * ## Changes Made:
- * 
- * ### contacts.iViewContent
- * New boolean column that controls whether the user wants to see content
- * (activities, projects, offers) from this contact in their feeds and views.
- * 
- * - `TRUE` (default): User sees all content from this contact
- * - `FALSE`: User's interface filters out content from this contact
- * 
- * ## Use Cases:
- * 
- * 1. **Privacy Management**: Users can maintain contacts for trust/verification
- *    purposes while limiting information exposure
- * 
- * 2. **Feed Curation**: Users can curate their activity feeds by selectively
- *    hiding content from certain contacts
- * 
- * 3. **Professional Separation**: Users can separate professional and personal
- *    networks while maintaining cryptographic trust relationships
- * 
- * 4. **Graduated Privacy**: Users can add contacts with limited visibility
- *    initially, then expand access as trust develops
- * 
- * ## Privacy Architecture:
- * 
- * This column works in conjunction with TimeSafari's broader privacy model:
- * - Contact relationships are still maintained for verification
- * - Cryptographic trust is preserved regardless of content visibility
- * - Users can change visibility settings at any time
- * - The setting only affects the local user's view, not the contact's capabilities
- * 
- * ## Default Behavior:
- * 
- * All existing contacts default to `TRUE` (visible) to maintain current
- * user experience. New contacts will also default to visible, with users
- * able to adjust visibility as needed.
- */
-registerMigration({
-  name: "002_add_iViewContent_to_contacts",
-  sql: `
-    -- Add content visibility control to contacts table
-    -- This allows users to manage what content they see from each contact
-    -- while maintaining the cryptographic trust relationship
-    ALTER TABLE contacts ADD COLUMN iViewContent BOOLEAN DEFAULT TRUE;
-  `,
-});
-
-/**
- * Template for Future Migrations
- * 
- * When adding new migrations, follow this pattern:
- * 
- * ```typescript
- * registerMigration({
- *   name: "003_descriptive_name",
- *   sql: `
- *     -- Clear comment explaining what this migration does
- *     -- and why it's needed
- *     
- *     ALTER TABLE existing_table ADD COLUMN new_column TYPE DEFAULT value;
- *     
- *     -- Or create new tables:
- *     CREATE TABLE new_table (
- *       id INTEGER PRIMARY KEY,
- *       -- ... other columns with comments
- *     );
- *     
- *     -- Initialize any required data
- *     INSERT INTO new_table (column) VALUES ('initial_value');
- *   `,
- * });
- * ```
- * 
- * ## Migration Best Practices:
- * 
- * 1. **Clear Naming**: Use descriptive names that explain the change
- * 2. **Documentation**: Document the purpose and impact of each change
- * 3. **Backward Compatibility**: Consider how changes affect existing data
- * 4. **Default Values**: Provide sensible defaults for new columns
- * 5. **Data Migration**: Include any necessary data transformation
- * 6. **Testing**: Test migrations on representative data sets
- * 7. **Performance**: Consider the impact on large datasets
- * 
- * ## Schema Evolution Guidelines:
- * 
- * - **Additive Changes**: Prefer adding new tables/columns over modifying existing ones
- * - **Nullable Columns**: New columns should be nullable or have defaults
- * - **Index Creation**: Add indexes for new query patterns
- * - **Data Integrity**: Maintain referential integrity and constraints
- * - **Privacy Preservation**: Ensure new schema respects privacy principles
