# Memory Architecture API Documentation

## Overview

Gemini Flow v1.0.4 features a sophisticated memory architecture built on SQLite with WAL mode, providing high-performance persistent storage for multi-agent coordination, collective intelligence, and cross-session knowledge sharing. The system achieves 396K+ operations per second with <10ms average access times.

  };
}
```

## Memory Management Patterns

### Namespace Organization

```typescript
interface NamespaceStrategy {
  user: 'User-specific data and preferences';
  session: 'Session-scoped temporary data';
  agent: 'Agent-specific memory and state';
  swarm: 'Swarm coordination and shared state';
  task: 'Task execution context and results';
  system: 'System configuration and metadata';
  cache: 'Temporary caching with TTL';
  shared: 'Cross-agent shared knowledge';
}

// Example namespace usage
const userPrefs = await memory.store('preferences', userData, { 
  namespace: 'user',
  ttl: 86400 // 24 hours
});

const sessionData = await memory.store('workflow-state', workflowState, {
  namespace: 'session',
  ttl: 3600 // 1 hour
});
```

### TTL Strategies

```typescript
interface TTLStrategies {
  temporary: 300;      // 5 minutes - temp cache
  session: 3600;       // 1 hour - session data
  user: 86400;         // 24 hours - user preferences
  persistent: null;    // No expiration - permanent data
  weekly: 604800;      // 7 days - analytics data
  monthly: 2592000;    // 30 days - historical data
}
```

### Data Patterns

```typescript
// Agent coordination pattern
interface AgentCoordination {
  store: {
    key: 'agent-{agentId}-status',
    value: AgentStatus,
    namespace: 'agent',
    ttl: 300
  };
  retrieve: {
    pattern: 'agent-*-status',
    namespace: 'agent'
  };
}

// Swarm consensus pattern
interface SwarmConsensus {
  store: {
    key: 'swarm-{swarmId}-proposal-{proposalId}',
    value: ConsensusData,
    namespace: 'swarm',
    ttl: 1800
  };
  search: {
    pattern: 'swarm-{swarmId}-proposal-*',
    namespace: 'swarm'
  };
}

// Task execution pattern
interface TaskExecution {
  store: {
    key: 'task-{taskId}-state',
    value: TaskState,
    namespace: 'task',
    ttl: 7200
  };
  checkpoint: {
    key: 'task-{taskId}-checkpoint-{timestamp}',
    value: TaskCheckpoint,
    namespace: 'task',
    ttl: 86400
  };
}
```

## Advanced Features

### Encryption Support

```typescript
interface EncryptionConfig {
  algorithm: 'aes-256-gcm';
  keyDerivation: 'scrypt';
  autoEncrypt: string[]; // Patterns that auto-encrypt
  encryptionKey: string; // Environment variable
}

// Store encrypted data
await memory.store('sensitive-config', sensitiveData, {
  namespace: 'system',
  encrypted: true,
  ttl: 3600
});
```

### Backup and Recovery

```typescript
interface BackupConfig {
  automatic: {
    enabled: true,
    interval: '6h',
    retention: 30, // days
    location: '.hive-mind/backups'
  };
  manual: {
    command: 'gemini-flow memory backup',
    format: 'sqlite' | 'json' | 'sql',
    compression: 'gzip'
  };
}

// Create backup
await memory.backup({
  path: './backup-2025-08-03.db',
  format: 'sqlite',
  compress: true
});

// Restore from backup
await memory.restore({
  path: './backup-2025-08-03.db',
  merge: false // Replace existing data
});
```

### Migration Support

```typescript
interface MigrationConfig {
  version: '1.0.4',
  migrations: [
    {
      version: '1.0.3',
      description: 'Add neural patterns table',
      up: 'CREATE TABLE neural_patterns...',
      down: 'DROP TABLE neural_patterns'
    }
  ];
}

// Run migrations
await memory.migrate({
  fromVersion: '1.0.3',
  toVersion: '1.0.4',
  dryRun: false
});
```

## TypeScript API

### Core Interfaces

```typescript
import { MemoryManager } from '@clduab11/gemini-flow';

class MemoryManager {
  constructor(config?: MemoryConfig);
  
  // Core operations
  async store(key: string, value: any, options?: StoreOptions): Promise<StoreResult>;
  async retrieve(key: string, options?: RetrieveOptions): Promise<any>;
  async delete(key: string, options?: DeleteOptions): Promise<boolean>;
  async search(pattern: string, options?: SearchOptions): Promise<SearchResult[]>;
  async clear(namespace?: string): Promise<void>;
  
  // Batch operations
  async batchStore(items: MemoryItem[]): Promise<BatchResult>;
  async batchRetrieve(keys: string[], options?: BatchOptions): Promise<any[]>;
  async batchDelete(keys: string[], options?: BatchOptions): Promise<boolean[]>;
  
  // Advanced operations
  async backup(options: BackupOptions): Promise<BackupResult>;
  async restore(options: RestoreOptions): Promise<RestoreResult>;
  async migrate(options: MigrationOptions): Promise<MigrationResult>;
  
  // Monitoring and metrics
  async getMetrics(): Promise<MemoryMetrics>;
  async getStats(namespace?: string): Promise<MemoryStats>;
  async healthCheck(): Promise<HealthStatus>;
}

interface StoreOptions {
  namespace?: string;
  ttl?: number;
  tags?: string[];
  encrypted?: boolean;
  metadata?: object;
}

interface SearchOptions {
  namespace?: string;
  limit?: number;
  offset?: number;
  sortBy?: 'key' | 'created_at' | 'access_count';
  sortOrder?: 'asc' | 'desc';
  includeExpired?: boolean;
}

interface MemoryMetrics {
  totalKeys: number;
  totalSize: number;
  namespaces: Record<string, NamespaceStats>;
  performance: PerformanceStats;
  cache: CacheStats;
}
```

### Usage Examples

```typescript
import { MemoryManager } from '@clduab11/gemini-flow';

// Initialize memory manager
const memory = new MemoryManager({
  dbPath: './.hive-mind/hive.db',
  walMode: true,
  cacheSize: 32768
});

// Store agent state
await memory.store('agent-status', {
  id: 'agent-1234',
  status: 'active',
  capabilities: ['coder', 'reviewer'],
  lastActivity: Date.now()
}, {
  namespace: 'agents',
  ttl: 300,
  tags: ['status', 'agent']
});

// Retrieve and update
const agentStatus = await memory.retrieve('agent-status', {
  namespace: 'agents'
});

// Search for similar agents
const activeAgents = await memory.search('agent-*', {
  namespace: 'agents',
  limit: 10
});

// Batch operations for efficiency
const batchData = [
  { key: 'task-1', value: { status: 'completed' }},
  { key: 'task-2', value: { status: 'running' }},
  { key: 'task-3', value: { status: 'pending' }}
];

await memory.batchStore(batchData.map(item => ({
  ...item,
  namespace: 'tasks',
  ttl: 3600
})));

// Performance monitoring
const metrics = await memory.getMetrics();
console.log(`Cache hit rate: ${metrics.cache.hitRate}%`);
console.log(`Average read time: ${metrics.performance.avgReadTime}ms`);
```

## Error Handling

### Error Types

```typescript
enum MemoryErrorTypes {
  CONNECTION_FAILED = 'CONNECTION_FAILED',
  INVALID_KEY = 'INVALID_KEY',
  VALUE_TOO_LARGE = 'VALUE_TOO_LARGE',
  NAMESPACE_NOT_FOUND = 'NAMESPACE_NOT_FOUND',
  ENCRYPTION_FAILED = 'ENCRYPTION_FAILED',
  TTL_EXPIRED = 'TTL_EXPIRED',
  PERMISSION_DENIED = 'PERMISSION_DENIED',
  QUOTA_EXCEEDED = 'QUOTA_EXCEEDED',
  BACKUP_FAILED = 'BACKUP_FAILED',
  MIGRATION_FAILED = 'MIGRATION_FAILED'
}

class MemoryError extends Error {
  constructor(
    message: string,
    public code: MemoryErrorTypes,
    public recoverable: boolean = true,
    public metadata?: object
  ) {
    super(message);
  }
}
```

### Recovery Strategies

```typescript
async function robustMemoryOperation<T>(
  operation: () => Promise<T>,
  retries: number = 3
): Promise<T> {
  for (let attempt = 1; attempt <= retries; attempt++) {
    try {
      return await operation();
    } catch (error) {
      if (error instanceof MemoryError) {
        switch (error.code) {
          case MemoryErrorTypes.CONNECTION_FAILED:
            if (attempt < retries) {
              await delay(1000 * attempt); // Exponential backoff
              continue;
            }
            break;
            
          case MemoryErrorTypes.VALUE_TOO_LARGE:
            // Compress or split the value
            throw new Error('Value too large - consider compression');
            
          case MemoryErrorTypes.TTL_EXPIRED:
            // Refresh the data
            return await refreshData();
            
          case MemoryErrorTypes.QUOTA_EXCEEDED:
            // Clean up expired entries
            await cleanupExpiredEntries();
            continue;
        }
      }
      
      if (attempt === retries) {
        throw error;
      }
    }
  }
}
```

## Security Considerations

### Access Control

```typescript
interface SecurityConfig {
  authentication: {
    enabled: true,
    method: 'api-key' | 'jwt' | 'oauth',
    keyRotation: '30d'
  };
  authorization: {
    enabled: true,
    roleBasedAccess: true,
    namespaceIsolation: true
  };
  encryption: {
    atRest: true,
    inTransit: true,
    keyManagement: 'vault' | 'env' | 'file'
  };
  audit: {
    enabled: true,
    logLevel: 'info',
    retention: '90d'
  };
}
```

### Data Protection

```typescript
// Sensitive data handling
const sensitiveData = {
  apiKeys: 'encrypted',
  userCredentials: 'hashed',
  personalData: 'encrypted',
  financialData: 'encrypted+audit'
};

// Automatic encryption patterns
const autoEncryptPatterns = [
  '*-credentials',
  '*-api-key',
  'user-*-personal',
  '*-financial-*'
];
```
