# Integration Test Fix Coordination Summary

## Quick Reference

| Agent | Category | Files | Tests | Priority | Dependencies |
|-------|----------|-------|-------|----------|--------------|
| 1 | Database Isolation | 4 files | 9 tests | HIGH | None |
| 2 | MSW Setup | 1 file | 6 tests | HIGH | None |
| 3 | MCP Error Handling | 1 file | 16 tests | MEDIUM | Agent 2 |
| 4 | FTS5 Search | 1 file | 7 tests | MEDIUM | Agent 1 |
| 5 | Performance | 2 files | 15 tests | LOW | All others |
| 6 | Session Management | 1 file | 5 tests | MEDIUM | Agents 2, 3 |

## Execution Order

```
Phase 1 (Parallel):
├── Agent 1: Database Isolation
└── Agent 2: MSW Setup

Phase 2 (Parallel):
├── Agent 3: MCP Error Handling (after Agent 2)
├── Agent 4: FTS5 Search (after Agent 1)
└── Agent 6: Session Management (after Agent 2)

Phase 3:
└── Agent 5: Performance (after all others)
```

## Key Shared Resources

### 1. Test Database Configuration
**Owner**: Agent 1
```typescript
// Shared pattern for database isolation
const createTestDatabase = () => {
  return new Database(`:memory:test-${Date.now()}-${Math.random()}`);
};
```

### 2. MSW Server Instance
**Owner**: Agent 2
```typescript
// Global MSW server configuration
const server = setupServer(...handlers);
```

### 3. MCP Client Configuration
**Owner**: Agent 3
```typescript
// Standard MCP client setup
const mcpClient = new MCPClient({ timeout: 10000 });
```

## Communication Points

### Critical Handoffs
1. **Agent 1 → Agent 4**: Database schema and isolation strategy
2. **Agent 2 → Agent 3, 6**: MSW handler patterns and setup
3. **Agent 3 → Agent 6**: Error handling patterns for sessions
4. **All → Agent 5**: Completion status for baseline establishment

### Blocker Protocol
If blocked:
1. Update your progress file immediately
2. Tag the blocking agent in coordination doc
3. Provide specific details of what's needed
4. Consider temporary workaround if possible

## Success Verification

### Individual Agent Verification
```bash
# Agent 1
npm test tests/integration/database/node-repository.test.ts
npm test tests/integration/database/transactions.test.ts
npm test tests/integration/database/connection-management.test.ts
npm test tests/integration/database/template-repository.test.ts

# Agent 2
npm test tests/integration/msw-setup.test.ts

# Agent 3
npm test tests/integration/mcp-protocol/error-handling.test.ts

# Agent 4
npm test tests/integration/database/fts5-search.test.ts

# Agent 5
npm test tests/integration/mcp-protocol/performance.test.ts
npm test tests/integration/database/performance.test.ts

# Agent 6
npm test tests/integration/mcp-protocol/session-management.test.ts
```

### Full Integration Test
```bash
# After all agents complete
npm test tests/integration/

# Expected output: All 58 tests passing
```

## Progress Dashboard

```
Overall Progress: [⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜] 0/58

Agent 1 - Database: [⬜⬜⬜⬜⬜⬜⬜⬜⬜] 0/9
Agent 2 - MSW:      [⬜⬜⬜⬜⬜⬜] 0/6
Agent 3 - MCP:      [⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜] 0/16
Agent 4 - FTS5:     [⬜⬜⬜⬜⬜⬜⬜] 0/7
Agent 5 - Perf:     [⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜⬜] 0/15
Agent 6 - Session:  [⬜⬜⬜⬜⬜] 0/5
```

## Common Patterns Reference

### Error Handling Pattern
```typescript
await expect(async () => {
  await operation();
}).rejects.toThrow(/expected pattern/);
```

### Performance Threshold Pattern
```typescript
const threshold = process.env.CI ? 200 : 100;
expect(duration).toBeLessThan(threshold);
```

### Database Isolation Pattern
```typescript
beforeEach(async () => {
  db = createTestDatabase();
  await initializeSchema(db);
});

afterEach(async () => {
  await db.close();
});
```
