+# Absurd SQL - Cursor Development Guide
+
+## Project Overview
+Absurd SQL is a backend implementation for sql.js that enables persistent SQLite databases in the browser by using IndexedDB as a block storage system. This guide provides rules and best practices for developing with this project in Cursor.
+
+## Project Structure
+```
+absurd-sql/
+├── src/               # Source code
+├── dist/             # Built files
+├── package.json      # Dependencies and scripts
+├── rollup.config.js  # Build configuration
+└── jest.config.js    # Test configuration
+```
+
+## Development Rules
+
+### 1. Worker Thread Requirements
+- All SQL operations MUST be performed in a worker thread
+- Main thread should only handle worker initialization and communication
+- Never block the main thread with database operations
+
+### 2. Code Organization
+- Keep worker code in separate files (e.g., `*.worker.js`)
+- Use ES modules for imports/exports
+- Follow the project's existing module structure
+
+### 3. Required Headers
+When developing locally or deploying, ensure these headers are set:
+```
+Cross-Origin-Opener-Policy: same-origin
+Cross-Origin-Embedder-Policy: require-corp
+```
+
+### 4. Browser Compatibility
+- Primary target: Modern browsers with SharedArrayBuffer support
+- Fallback mode: Safari (with limitations)
+- Always test in both modes
+
+### 5. Database Configuration
+Recommended database settings:
+```sql
+PRAGMA journal_mode=MEMORY;
+PRAGMA page_size=8192;  -- Optional, but recommended
+```
+
+### 6. Development Workflow
+1. Install dependencies:
+   ```bash
+   yarn add @jlongster/sql.js absurd-sql
+   ```
+
+2. Development commands:
+   - `yarn build` - Build the project
+   - `yarn jest` - Run tests
+   - `yarn serve` - Start development server
+
+### 7. Testing Guidelines
+- Write tests for both SharedArrayBuffer and fallback modes
+- Use Jest for testing
+- Include performance benchmarks for critical operations
+
+### 8. Performance Considerations
+- Use bulk operations when possible
+- Monitor read/write performance
+- Consider using transactions for multiple operations
+- Avoid unnecessary database connections
+
+### 9. Error Handling
+- Implement proper error handling for:
+  - Worker initialization failures
+  - Database connection issues
+  - Concurrent access conflicts (in fallback mode)
+  - Storage quota exceeded scenarios
+
+### 10. Security Best Practices
+- Never expose database operations directly to the client
+- Validate all SQL queries
+- Implement proper access controls
+- Handle sensitive data appropriately
+
+### 11. Code Style
+- Follow ESLint configuration
+- Use async/await for asynchronous operations
+- Document complex database operations
+- Include comments for non-obvious optimizations
+
+### 12. Debugging
+- Use `jest-debug` for debugging tests
+- Monitor IndexedDB usage in browser dev tools
+- Check worker communication in console
+- Use performance monitoring tools
+
+## Common Patterns
+
+### Worker Initialization
+```javascript
+// Main thread
+import { initBackend } from 'absurd-sql/dist/indexeddb-main-thread';
+
+function init() {
+  let worker = new Worker(new URL('./index.worker.js', import.meta.url));
+  initBackend(worker);
+}
+```
+
+### Database Setup
+```javascript
+// Worker thread
+import initSqlJs from '@jlongster/sql.js';
+import { SQLiteFS } from 'absurd-sql';
+import IndexedDBBackend from 'absurd-sql/dist/indexeddb-backend';
+
+async function setupDatabase() {
+  let SQL = await initSqlJs({ locateFile: file => file });
+  let sqlFS = new SQLiteFS(SQL.FS, new IndexedDBBackend());
+  SQL.register_for_idb(sqlFS);
+  
+  SQL.FS.mkdir('/sql');
+  SQL.FS.mount(sqlFS, {}, '/sql');
+  
+  return new SQL.Database('/sql/db.sqlite', { filename: true });
+}
+```
+
+## Troubleshooting
+
+### Common Issues
+1. SharedArrayBuffer not available
+   - Check COOP/COEP headers
+   - Verify browser support
+   - Test fallback mode
+
+2. Worker initialization failures
+   - Check file paths
+   - Verify module imports
+   - Check browser console for errors
+
+3. Performance issues
+   - Monitor IndexedDB usage
+   - Check for unnecessary operations
+   - Verify transaction usage

+  for (const contact of contacts) {
+    await db.run(`
+      INSERT INTO contacts (id, did, name, created_at, updated_at)
+      VALUES (?, ?, ?, ?, ?)
+    `, [contact.id, contact.did, contact.name, contact.createdAt, contact.updatedAt]);
+  }
+  await db.exec('COMMIT;');
+} catch (error) {
+  await db.exec('ROLLBACK;');
+  throw error;
+}
+```
+
+## Migration Helper Functions
+
+### 1. Data Export (Dexie to JSON)
+```typescript
+async function exportDexieData(): Promise<MigrationData> {
+  const db = new Dexie('TimeSafariDB');
+  
+  return {
+    accounts: await db.accounts.toArray(),
+    settings: await db.settings.toArray(),
+    contacts: await db.contacts.toArray(),
+    metadata: {
+      version: '1.0.0',
+      timestamp: Date.now(),
+      dexieVersion: Dexie.version
+    }
+  };
+}
+```
+
+### 2. Data Import (JSON to absurd-sql)
+```typescript
+async function importToAbsurdSql(data: MigrationData): Promise<void> {
+  await db.exec('BEGIN TRANSACTION;');
+  try {
+    // Import accounts
+    for (const account of data.accounts) {
+      await db.run(`
+        INSERT INTO accounts (did, public_key_hex, created_at, updated_at)
+        VALUES (?, ?, ?, ?)
+      `, [account.did, account.publicKeyHex, account.createdAt, account.updatedAt]);
+    }
+    
+    // Import settings
+    for (const setting of data.settings) {
+      await db.run(`
+        INSERT INTO settings (key, value, updated_at)
+        VALUES (?, ?, ?)
+      `, [setting.key, setting.value, setting.updatedAt]);
+    }
+    
+    // Import contacts
+    for (const contact of data.contacts) {
+      await db.run(`
+        INSERT INTO contacts (id, did, name, created_at, updated_at)
+        VALUES (?, ?, ?, ?, ?)
+      `, [contact.id, contact.did, contact.name, contact.createdAt, contact.updatedAt]);
+    }
+    await db.exec('COMMIT;');
+  } catch (error) {
+    await db.exec('ROLLBACK;');
+    throw error;
+  }
+}
+```
+
+### 3. Verification
+```typescript
+async function verifyMigration(dexieData: MigrationData): Promise<boolean> {
+  // Verify account count
+  const accountResult = await db.exec('SELECT COUNT(*) as count FROM accounts');
+  const accountCount = accountResult[0].values[0][0];
+  if (accountCount !== dexieData.accounts.length) {
+    return false;
+  }
+  
+  // Verify settings count
+  const settingsResult = await db.exec('SELECT COUNT(*) as count FROM settings');
+  const settingsCount = settingsResult[0].values[0][0];
+  if (settingsCount !== dexieData.settings.length) {
+    return false;
+  }
+  
+  // Verify contacts count
+  const contactsResult = await db.exec('SELECT COUNT(*) as count FROM contacts');
+  const contactsCount = contactsResult[0].values[0][0];
+  if (contactsCount !== dexieData.contacts.length) {
+    return false;
+  }
+  
+  // Verify data integrity
+  for (const account of dexieData.accounts) {
+    const result = await db.exec(
+      'SELECT * FROM accounts WHERE did = ?',
+      [account.did]
+    );
+    const migratedAccount = result[0]?.values[0];
+    if (!migratedAccount || 
+        migratedAccount[1] !== account.publicKeyHex) { // public_key_hex is second column
+      return false;
+    }
+  }
+  
+  return true;
+}
+```
+
+## Performance Considerations
+
+### 1. Indexing
+- Dexie automatically creates indexes based on the schema
+- absurd-sql requires explicit index creation
+- Added indexes for frequently queried fields
+- Use `PRAGMA journal_mode=MEMORY;` for better performance
+
+### 2. Batch Operations
+- Dexie has built-in bulk operations
+- absurd-sql uses transactions for batch operations
+- Consider chunking large datasets
+- Use prepared statements for repeated queries
+
+### 3. Query Optimization
+- Dexie uses IndexedDB's native indexing
+- absurd-sql requires explicit query optimization
+- Use prepared statements for repeated queries
+- Consider using `PRAGMA synchronous=NORMAL;` for better performance
+
+## Error Handling
+
+### 1. Common Errors
+```typescript
+// Dexie errors
+try {
+  await db.accounts.add(account);
+} catch (error) {
+  if (error instanceof Dexie.ConstraintError) {
+    // Handle duplicate key
+  }
+}
+
+// absurd-sql errors
+try {
+  await db.run(`
+    INSERT INTO accounts (did, public_key_hex, created_at, updated_at)
+    VALUES (?, ?, ?, ?)
+  `, [account.did, account.publicKeyHex, account.createdAt, account.updatedAt]);
+} catch (error) {
+  if (error.message.includes('UNIQUE constraint failed')) {
+    // Handle duplicate key
+  }
+}
+```
+
+### 2. Transaction Recovery
+```typescript
+// Dexie transaction
+try {
+  await db.transaction('rw', db.accounts, async () => {
+    // Operations
+  });
+} catch (error) {
+  // Dexie automatically rolls back
+}
+
+// absurd-sql transaction
+try {
+  await db.exec('BEGIN TRANSACTION;');
+  // Operations
+  await db.exec('COMMIT;');
+} catch (error) {
+  await db.exec('ROLLBACK;');
+  throw error;
+}
+```
+
+## Migration Strategy
+
+1. **Preparation**
+   - Export all Dexie data
+   - Verify data integrity
+   - Create SQLite schema
+   - Setup indexes
+
+2. **Migration**
+   - Import data in transactions
+   - Verify each batch
+   - Handle errors gracefully
+   - Maintain backup
+
+3. **Verification**
+   - Compare record counts
+   - Verify data integrity
+   - Test common queries
+   - Validate relationships
+
+4. **Cleanup**
+   - Remove Dexie database
+   - Clear IndexedDB storage
+   - Update application code
+   - Remove old dependencies

+# Secure Storage Implementation Guide for TimeSafari App
+
+## Overview
+
+This document outlines the implementation of secure storage for the TimeSafari app. The implementation focuses on:
+
+1. **Platform-Specific Storage Solutions**:
+   - Web: SQLite with IndexedDB backend (absurd-sql)
+   - Electron: SQLite with Node.js backend
+   - Native: (Planned) SQLCipher with platform-specific secure storage
+
+2. **Key Features**:
+   - SQLite-based storage using absurd-sql for web
+   - Platform-specific service factory pattern
+   - Consistent API across platforms
+   - Migration support from Dexie.js
+
+## Quick Start
+
+### 1. Installation
+
+```bash
+# Core dependencies
+npm install @jlongster/sql.js
+npm install absurd-sql
+
+# Platform-specific dependencies (for future native support)
+npm install @capacitor/preferences
+npm install @capacitor-community/biometric-auth
+```
+
+### 2. Basic Usage
+
+```typescript
+// Using the platform service
+import { PlatformServiceFactory } from '../services/PlatformServiceFactory';
+
+// Get platform-specific service instance
+const platformService = PlatformServiceFactory.getInstance();
+
+// Example database operations
+async function example() {
+  try {
+    // Query example
+    const result = await platformService.dbQuery(
+      "SELECT * FROM accounts WHERE did = ?",
+      [did]
+    );
+
+    // Execute example
+    await platformService.dbExec(
+      "INSERT INTO accounts (did, public_key_hex) VALUES (?, ?)",
+      [did, publicKeyHex]
+    );
+
+    } catch (error) {
+    console.error('Database operation failed:', error);
+  }
+}
+```
+
+### 3. Platform Detection
+
+```typescript
+// src/services/PlatformServiceFactory.ts
+export class PlatformServiceFactory {
+  static getInstance(): PlatformService {
+    if (process.env.ELECTRON) {
+      // Electron platform
+      return new ElectronPlatformService();
+    } else {
+      // Web platform (default)
+      return new AbsurdSqlDatabaseService();
+    }
+  }
+}
+```
+
+### 4. Current Implementation Details
+
+#### Web Platform (AbsurdSqlDatabaseService)
+
+The web platform uses absurd-sql with IndexedDB backend:
+
+```typescript
+// src/services/AbsurdSqlDatabaseService.ts
+export class AbsurdSqlDatabaseService implements PlatformService {
+  private static instance: AbsurdSqlDatabaseService | null = null;
+  private db: AbsurdSqlDatabase | null = null;
+  private initialized: boolean = false;
+      
+  // Singleton pattern
+  static getInstance(): AbsurdSqlDatabaseService {
+    if (!AbsurdSqlDatabaseService.instance) {
+      AbsurdSqlDatabaseService.instance = new AbsurdSqlDatabaseService();
+    }
+    return AbsurdSqlDatabaseService.instance;
+  }
+
+  // Database operations
+  async dbQuery(sql: string, params: unknown[] = []): Promise<QueryExecResult[]> {
+    await this.waitForInitialization();
+    return this.queueOperation<QueryExecResult[]>("query", sql, params);
+    }
+
+  async dbExec(sql: string, params: unknown[] = []): Promise<void> {
+    await this.waitForInitialization();
+    await this.queueOperation<void>("run", sql, params);
+  }
+}
+```
+
+Key features:
+- Uses absurd-sql for SQLite in the browser
+- Implements operation queuing for thread safety
+- Handles initialization and connection management
+- Provides consistent API across platforms
+
+### 5. Migration from Dexie.js
+
+The current implementation supports gradual migration from Dexie.js:
+
+```typescript
+// Example of dual-storage pattern
+async function getAccount(did: string): Promise<Account | undefined> {
+  // Try SQLite first
+  const platform = PlatformServiceFactory.getInstance();
+  let account = await platform.dbQuery(
+    "SELECT * FROM accounts WHERE did = ?",
+    [did]
+  );
+
+  // Fallback to Dexie if needed
+  if (USE_DEXIE_DB) {
+    account = await db.accounts.get(did);
+  }
+
+  return account;
+   }
+```
+
+#### A. Modifying Code
+
+When converting from Dexie.js to SQL-based implementation, follow these patterns:
+
+1. **Database Access Pattern**
+   ```typescript
+   // Before (Dexie)
+   const result = await db.table.where("field").equals(value).first();
+
+   // After (SQL)
+   const platform = PlatformServiceFactory.getInstance();
+   let result = await platform.dbQuery(
+     "SELECT * FROM table WHERE field = ?",
+     [value]
+   );
+   result = databaseUtil.mapQueryResultToValues(result);
+   
+   // Fallback to Dexie if needed
+   if (USE_DEXIE_DB) {
+     result = await db.table.where("field").equals(value).first();
+   }
+   ```
+
+2. **Update Operations**
+   ```typescript
+   // Before (Dexie)
+   await db.table.where("id").equals(id).modify(changes);
+
+   // After (SQL)
+   // For settings updates, use the utility methods:
+   await databaseUtil.updateDefaultSettings(changes);
+   // OR
+   await databaseUtil.updateAccountSettings(did, changes);
+
+   // For other tables, use direct SQL:
+   const platform = PlatformServiceFactory.getInstance();
+   await platform.dbExec(
+     "UPDATE table SET field1 = ?, field2 = ? WHERE id = ?",
+     [changes.field1, changes.field2, id]
+   );
+
+   // Fallback to Dexie if needed
+   if (USE_DEXIE_DB) {
+     await db.table.where("id").equals(id).modify(changes);
+   }
+   ```
+
+3. **Insert Operations**
+   ```typescript
+   // Before (Dexie)
+   await db.table.add(item);
+
+   // After (SQL)
+   const platform = PlatformServiceFactory.getInstance();
+   const columns = Object.keys(item);
+   const values = Object.values(item);
+   const placeholders = values.map(() => '?').join(', ');
+   const sql = `INSERT INTO table (${columns.join(', ')}) VALUES (${placeholders})`;
+   await platform.dbExec(sql, values);
+
+   // Fallback to Dexie if needed
+   if (USE_DEXIE_DB) {
+     await db.table.add(item);
+   }
+   ```
+
+4. **Delete Operations**
+   ```typescript
+   // Before (Dexie)
+   await db.table.where("id").equals(id).delete();
+
+   // After (SQL)
+   const platform = PlatformServiceFactory.getInstance();
+   await platform.dbExec("DELETE FROM table WHERE id = ?", [id]);
+
+   // Fallback to Dexie if needed
+   if (USE_DEXIE_DB) {
+     await db.table.where("id").equals(id).delete();
+   }
+   ```
+
+5. **Result Processing**
+   ```typescript
+   // Before (Dexie)
+   const items = await db.table.toArray();
+
+   // After (SQL)
+   const platform = PlatformServiceFactory.getInstance();
+   let items = await platform.dbQuery("SELECT * FROM table");
+   items = databaseUtil.mapQueryResultToValues(items);
+
+   // Fallback to Dexie if needed
+   if (USE_DEXIE_DB) {
+     items = await db.table.toArray();
+   }
+   ```
+
+6. **Using Utility Methods**
+
+When working with settings or other common operations, use the utility methods in `db/index.ts`:
+
+```typescript
+// Settings operations
+await databaseUtil.updateDefaultSettings(settings);
+await databaseUtil.updateAccountSettings(did, settings);
+const settings = await databaseUtil.retrieveSettingsForDefaultAccount();
+const settings = await databaseUtil.retrieveSettingsForActiveAccount();
+
+// Logging operations
+await databaseUtil.logToDb(message);
+await databaseUtil.logConsoleAndDb(message, showInConsole);
+```
+
+Key Considerations:
+- Always use `databaseUtil.mapQueryResultToValues()` to process SQL query results
+- Use utility methods from `db/index.ts` when available instead of direct SQL
+- Keep Dexie fallbacks wrapped in `if (USE_DEXIE_DB)` checks
+- For queries that return results, use `let` variables to allow Dexie fallback to override
+- For updates/inserts/deletes, execute both SQL and Dexie operations when `USE_DEXIE_DB` is true
+
+Example Migration:
+```typescript
+// Before (Dexie)
+export async function updateSettings(settings: Settings): Promise<void> {
+  await db.settings.put(settings);
+}
+
+// After (SQL)
+export async function updateSettings(settings: Settings): Promise<void> {
+  const platform = PlatformServiceFactory.getInstance();
+  const { sql, params } = generateUpdateStatement(
+    settings,
+    "settings",
+    "id = ?",
+    [settings.id]
+  );
+  await platform.dbExec(sql, params);
+}
+```
+
+Remember to:
+- Create database access code to use the platform service, putting it in front of the Dexie version
+- Instead of removing Dexie-specific code, keep it.
+
+  - For creates & updates & deletes, the duplicate code is fine.
+
+  - For queries where we use the results, make the setting from SQL into a 'let' variable, then wrap the Dexie code in a check for USE_DEXIE_DB from app.ts and if
+it's true then use that result instead of the SQL code's result.
+
+- Consider data migration needs, and warn if there are any potential migration problems
