## 1. Current State Analysis

### 1.1 Codebase Overview

```
Claude-Flow v2.7.47
├── Source Files: 376 TypeScript files (~130,000 lines)
├── Dependencies: agentic-flow (^1.9.4), ruv-swarm, flow-nexus
├── Architecture: Multi-layered (CLI, Core, MCP, Swarm, Hive-Mind)
└── Configuration: 14.2 MB across 7 directories
```

### 1.2 Architectural Strengths (Preserve)

- ✅ Event-driven architecture with centralized EventBus
- ✅ Interface-based design with dependency injection
- ✅ Clean backend abstraction (Memory, Transport)
- ✅ Circuit breaker patterns for reliability
- ✅ MCP protocol compliance (2024.11.5)
- ✅ Comprehensive agent template system (10+ templates)

### 1.3 Critical Weaknesses (Redesign)

| Issue | Current | Impact | v3 Solution |
|-------|---------|--------|-------------|
| **4 coordination systems** | SwarmCoordinator, Hive Mind, Maestro, AgentManager | Confusion, duplication | Single unified coordinator |
| **God objects** | Orchestrator (1,440 lines), AgentManager (1,736 lines) | Maintenance nightmare | Domain-driven decomposition |
| **Monolithic files** | index.ts (108KB), enterprise.ts (68KB) | Poor modularity | Microkernel architecture |
| **6 memory implementations** | No clear differentiation | Redundancy | AgentDB unified backend |
| **agentic-flow as add-on** | Not leveraged properly | Missing performance | Native foundation |

### 1.4 Dead Code Analysis

**Total Removable**: 15-20% of codebase (~8,000-12,000 lines)

| Category | Lines | Files | Priority |
|----------|-------|-------|----------|
| Deprecated API files | 524 | 3 | HIGH |
| Duplicate variants | 3,500 | 13 | HIGH |
| Backup/disabled files | ~500 | 8 | MEDIUM |
| Dual hive-mind implementation | 150-200KB | Multiple | MEDIUM |
| Incomplete TODO/FIXME | 50+ items | Various | LOW |

**Key Files to Remove**:
- `src/api/claude-client-v2.5.ts` (deprecated)
- `bin/pair-old.js`, `bin/pair-enhanced.backup.js`
- `bin/stream-chain.js.backup`, `bin/training-pipeline-old.js.bak`
- 8 pair programming variants (keep only `pair.js`)
- 5 stream-chain variants (keep only `stream-chain.js`)

## 2. Security Remediation (CRITICAL)

### 2.1 Critical Vulnerabilities (Fix Immediately)

#### CVE-1: Vulnerable Dependencies
```bash
# Immediate fix required
npm update @anthropic-ai/claude-code@^2.0.31
npm update @modelcontextprotocol/sdk@^1.24.0
npm audit fix --force
```

**Impact**: 13 vulnerabilities (7 high, 3 moderate, 3 low)

#### CVE-2: Weak Password Hashing
**Location**: `src/api/auth-service.ts:580-588`

```typescript
// CURRENT (INSECURE)
const hash = crypto.createHash('sha256')
  .update('salt' + password)  // Hardcoded salt!
  .digest('hex');

// v3 FIX (SECURE)
import * as bcrypt from 'bcrypt';
const SALT_ROUNDS = 12;
const hash = await bcrypt.hash(password, SALT_ROUNDS);
```

#### CVE-3: Hardcoded Default Credentials
**Location**: `src/api/auth-service.ts:602-643`

```typescript
// REMOVE these hardcoded credentials
email: 'admin@claude-flow.local'
password: 'admin123'  // CRITICAL RISK

// v3: Generate random on installation
const adminPassword = crypto.randomBytes(32).toString('hex');
```

### 2.2 High-Priority Issues

| Issue | Location | Fix |
|-------|----------|-----|
| Command injection | Multiple `spawn()` with `shell: true` | Use `execFile()` without shell |
| Path traversal | User-provided file paths | Validate with `path.resolve()` |
| Weak token generation | `Math.random()` | Use `crypto.randomBytes()` |
| Input validation gaps | Config commands | Add Joi/Zod schema validation |

### 2.3 Security Score Targets

| Stage | Score | Status |
|-------|-------|--------|
| Current (v2.7.47) | 45/100 | ❌ Not production ready |
| After critical fixes | 70/100 | ⚠️ Acceptable |
| v3.0.0 target | 90/100 | ✅ Production ready |

### 3.3 Core Adapter Implementation

```typescript
// src/v3/integrations/agentic-flow-adapter.ts
import { EnhancedAgentDBWrapper, AttentionCoordinator } from 'agentic-flow/core';

export class AgenticFlowAdapter {
  private wrapper: EnhancedAgentDBWrapper;
  private coordinator: AttentionCoordinator;

  constructor(config: AgenticFlowConfig) {
    this.wrapper = new EnhancedAgentDBWrapper({
      enableAttention: config.enableAttention ?? true,
      enableGNN: config.enableGNN ?? true,
      attentionConfig: { type: config.attentionType ?? 'flash' },
      runtimePreference: config.runtime ?? 'napi'
    });
  }

  async initialize(): Promise<void> {
    await this.wrapper.initialize();
    this.coordinator = new AttentionCoordinator(
      this.wrapper.getAttentionService()
    );
  }

  // Backward compatible agent creation
  async createAgent(template: string, options?: AgentOptions): Promise<string> {
    return await this.wrapper.spawnAgent(template, {
      sonaProfile: options?.learning ?? 'balanced',
      reflexionEnabled: options?.reflexion ?? true
    });
  }

  // Enhanced search with GNN
  async searchPatterns(query: string, k = 5): Promise<Pattern[]> {
    return await this.wrapper.gnnEnhancedSearch(query, { k });
  }

  // Consensus-based coordination
  async coordinateAgents(outputs: AgentOutput[]): Promise<Consensus> {
    return await this.coordinator.coordinateAgents(outputs, 'flash');
  }
}
```

### 3.4 Migration Strategy

#### Phase 1: Non-Breaking (v3.0.0)
- Add agentic-flow as optional enhancement
- Feature flag: `config.agenticFlow.enabled`
- All existing APIs continue to work

#### Phase 2: Gradual Enhancement (v3.1.0-v3.4.0)
- v3.1.0: Memory → AgentDB vector search
- v3.2.0: Coordination → Flash Attention
- v3.3.0: Agent selection → GNN-enhanced
- v3.4.0: Full SONA learning profiles

#### Phase 3: Unified (v4.0.0)
- agentic-flow as default engine
- Deprecate legacy implementations
- Full performance benefits

## 4. Windows Support via sql.js

### 4.1 Current Problem

```
Windows Installation Failure:
- better-sqlite3 requires native compilation
- node-gyp build fails on many Windows systems
- 17 files directly use better-sqlite3
```

### 4.2 Solution: Dual-Mode Provider

```typescript
// src/v3/memory/backends/database-provider.ts
export type DatabaseProvider = 'better-sqlite3' | 'sql.js' | 'json' | 'auto';

export async function createDatabase(
  path: string,
  options: { provider?: DatabaseProvider } = {}
): Promise<Database> {
  const provider = options.provider ?? 'auto';

  if (provider === 'auto') {
    // Platform-aware selection
    if (process.platform === 'win32') {
      try {
        // Try native first (if build tools available)
        return await createBetterSqlite(path);
      } catch {
        // Fall back to sql.js (always works)
        return await createSqlJs(path);
      }
    } else {
      // Linux/macOS: native is reliable
      return await createBetterSqlite(path);
    }
  }

  // Explicit provider selection
  switch (provider) {
    case 'better-sqlite3': return await createBetterSqlite(path);
    case 'sql.js': return await createSqlJs(path);
    case 'json': return await createJsonFallback(path);
  }
}
```

### 4.3 sql.js Implementation

```typescript
// src/v3/memory/backends/sqljs-backend.ts
import initSqlJs, { Database as SqlJsDatabase } from 'sql.js';

export class SqlJsBackend implements DatabaseBackend {
  private db: SqlJsDatabase;
  private wasmUrl: string;

  async initialize(path: string): Promise<void> {
    const SQL = await initSqlJs({
      locateFile: file => `${this.wasmUrl}/${file}`
    });

    // Load existing data or create new
    if (await fileExists(path)) {
      const buffer = await fs.readFile(path);
      this.db = new SQL.Database(buffer);
    } else {
      this.db = new SQL.Database();
    }
  }

  // Same interface as better-sqlite3
  prepare(sql: string): Statement {
    return new SqlJsStatement(this.db.prepare(sql));
  }

  exec(sql: string): void {
    this.db.exec(sql);
  }

  // Persist changes
  async persist(): Promise<void> {
    const data = this.db.export();
    await fs.writeFile(this.path, Buffer.from(data));
  }
}
```

### 4.4 Performance Comparison

| Operation | better-sqlite3 | sql.js | Verdict |
|-----------|----------------|--------|---------|
| Create swarm | 0.5ms | 1.5ms | ✅ Acceptable |
| Store memory | 1ms | 3ms | ✅ Acceptable |
| Query agents | 2ms | 6ms | ✅ Acceptable |
| Bulk insert (1000) | 10ms | 30ms | ⚠️ Noticeable |

**Optimization strategies**:
- Batch transactions (80% overhead reduction)
- Lazy persistence (30s intervals)
- Prepared statement caching

### 4.5 Package Changes

```json
// package.json
{
  "dependencies": {
    "sql.js": "^1.10.0"  // +1.2MB (WASM)
  },
  "optionalDependencies": {
    "better-sqlite3": "^12.2.0"  // Native, optional
  }
}
```

### 4.6 Feature Matrix

| Provider | Core Features | ReasoningBank | Vector Search | Platform |
|----------|---------------|---------------|---------------|----------|
| better-sqlite3 | ✅ | ✅ | ✅ | Linux/macOS |
| sql.js | ✅ | ❌ | ❌ | All (Windows) |
| JSON | ✅ | ❌ | ❌ | All (fallback) |

### 6.3 Settings Consolidation

**Current**: 9 settings files with overlapping content

**v3**: 4 purpose-specific files

```typescript
// settings.prod.json - Production configuration
{
  "hooks": {
    "PreToolUse": [...],     // Full hook suite
    "PostToolUse": [...],
    "PreCompact": [...],
    "Stop": [...]
  },
  "neural": { "enabled": true },
  "agenticFlow": { "enabled": true, "sona": "balanced" }
}

// settings.dev.json - Development configuration
{
  "hooks": {
    "PreToolUse": [...],     // Debug hooks
  },
  "debug": { "verbose": true, "tracing": true }
}

// settings.github.json - GitHub automation
{
  "hooks": {
    "PreToolUse": [...],     // GitHub-specific
  },
  "github": { "autoReview": true, "swarmReview": true }
}
```

### 6.4 Checkpoint Cleanup

```bash
# Archive old checkpoints (keep last 20)
cd .claude/checkpoints

# Count current
ls -1 | wc -l  # 3,720 files!

# Archive old ones
mkdir -p archive
find . -maxdepth 1 -name "*.json" -mtime +7 -exec mv {} archive/ \;

# Compress archive
tar -czf archive.tar.gz archive/
rm -rf archive/

# Result: 8.4MB → ~500KB
```

#### v3: 28 skills in 5 domain groups

```yaml
# .claude/skills/ai-coordination/swarm-orchestration/SKILL.md
---
name: swarm-orchestration
domain: ai-coordination
version: 3.0.0
triggers:
  - "orchestrate swarm"
  - "multi-agent"
  - "parallel agents"
agentic-flow:
  required: true
  features:
    - flash-attention
    - consensus-coordination
---
```

### 7.3 Commands Optimization

#### Current: 93 commands across 16 categories
#### v3: 93 commands in 5 logical groups

```
commands/
├── core/           # agents, swarm, sparc (18 commands)
├── platform/       # github, hive-mind, flow-nexus (22 commands)
├── operations/     # memory, training, monitoring (25 commands)
├── automation/     # hooks, workflows, coordination (18 commands)
└── utilities/      # analysis, optimization, helpers (10 commands)
```

### 7.4 Hooks Consolidation

**Problem**: Hooks defined in 3 places
- `.claude/settings-enhanced.json`
- `.claude/settings-complete.json`
- `.claude-plugin/hooks/hooks.json`

**v3 Solution**: Single source in `config.json`

```typescript

### 7.5 Hook Integration with agentic-flow

```typescript
// src/v3/hooks/learning-hooks.ts
export const agenticFlowHooks = {
  PreToolUse: async (context: HookContext) => {
    // Query similar past operations
    const patterns = await agenticFlow.searchPatterns(context.tool);
    if (patterns.length > 0) {
      context.suggestions = patterns.map(p => p.recommendation);
    }
  },

  PostToolUse: async (context: HookContext) => {
    // Store for learning
    await agenticFlow.storePattern(
      context.tool,
      context.result,
      context.success ? 1.0 : 0.0
    );
  },

  PostTask: async (context: HookContext) => {
    // Update agent skill library
    if (context.success && context.quality > 0.8) {
      await agenticFlow.addToSkillLibrary(
        context.agentId,
        context.taskType,
        context.output
      );
    }
  }
};
```

## 8. Backward Compatibility

### 8.1 Compatibility Layer Design

```typescript
// src/v3/compatibility/v2-adapter.ts
import { SwarmCoordinator as V3Coordinator } from '../coordination';
import { AgenticFlowAdapter } from '../integrations';

/**
 * v2 API compatibility layer
 * All v2.x code continues to work unchanged
 */
export class SwarmCoordinator {
  private v3: V3Coordinator;
  private adapter: AgenticFlowAdapter;

  // v2 API method signatures preserved
  async spawnAgent(profile: AgentProfile): Promise<string> {
    // Internally uses v3 with agentic-flow
    return await this.v3.createAgent(profile.type, {
      learning: true,  // v3 enhancement, transparent to v2 callers
      ...profile
    });
  }

  async assignTask(task: Task): Promise<void> {
    // v2 behavior preserved, v3 enhancements automatic
    await this.v3.executeTask(task);
  }

  // v2 event emissions preserved
  on(event: string, handler: Function): void {
    this.v3.on(event, handler);
  }
}
```

### 8.2 Configuration Migration

```typescript
// src/v3/compatibility/config-migrator.ts
export async function migrateConfig(v2Config: V2Config): Promise<V3Config> {
  return {
    version: '3.0.0',

    // Preserve all v2 settings
    ...v2Config,

    // Add v3 enhancements with sensible defaults
    agenticFlow: {
      enabled: true,
      attention: 'flash',
      sona: 'balanced',
      learning: true
    },

    // Migrate deprecated fields
    hooks: migrateHooks(v2Config.hooks),
    agents: migrateAgents(v2Config.agents)
  };
}

// Auto-migration on first run
export async function autoMigrate(): Promise<void> {
  const configPath = '.claude/config.json';
  const config = await loadConfig(configPath);

  if (!config.version || config.version < '3.0.0') {
    const migrated = await migrateConfig(config);
    await saveConfig(configPath, migrated);
    await backupConfig(configPath + '.v2.backup', config);
    console.log('✅ Configuration migrated to v3');
  }
}
```

### 8.3 Deprecation Strategy

```typescript
// Phase 1 (v3.0.0): Warnings only
/** @deprecated Use AgenticFlowAdapter.createAgent() instead */
export async function legacySpawnAgent(profile: AgentProfile): Promise<string> {
  console.warn('⚠️ legacySpawnAgent is deprecated. Use AgenticFlowAdapter.');
  return await agenticFlow.createAgent(profile.type, profile);
}

// Phase 2 (v3.2.0): Loud warnings
// Phase 3 (v4.0.0): Remove deprecated APIs
```

### 8.4 Testing Backward Compatibility

```typescript
// tests/v3/backward-compatibility.test.ts
describe('v2 API Compatibility', () => {
  it('should work with v2 SwarmCoordinator API', async () => {
    // v2 code unchanged
    const coordinator = new SwarmCoordinator();
    const agentId = await coordinator.spawnAgent({ type: 'coder' });
    await coordinator.assignTask({ description: 'test' });

    expect(agentId).toBeDefined();
  });

  it('should emit v2 events', async () => {
    const events: string[] = [];
    coordinator.on('agent:spawned', () => events.push('spawned'));
    coordinator.on('task:completed', () => events.push('completed'));

    await coordinator.spawnAgent({ type: 'coder' });
    await coordinator.assignTask({ description: 'test' });

    expect(events).toContain('spawned');
    expect(events).toContain('completed');
  });

  it('should migrate v2 config automatically', async () => {
    const v2Config = { agents: [...], hooks: [...] };  // v2 format
    const v3Config = await migrateConfig(v2Config);

    expect(v3Config.version).toBe('3.0.0');
    expect(v3Config.agenticFlow.enabled).toBe(true);
  });
});
```
