# Phase 1.1: Missing Route Registration - COMPLETE

## Summary
Successfully registered all 5 missing delegation client route groups in the Go backend server.

## Changes Made

### 1. Handler Registration Functions Added

#### `/backend/internal/handlers/execution_handler.go`
Added `RegisterExecutionRoutes()` function to register execution endpoints:
- `POST /api/v1/execution/run-tests` - Start test execution
- `GET /api/v1/execution/:executionId/status` - Get execution status
- `POST /api/v1/execution/:executionId/cancel` - Cancel execution
- `GET /api/v1/execution/:executionId/output` - Get execution output
- `GET /api/v1/execution/:executionId/recording` - Get execution recording

#### `/backend/internal/handlers/workflow_handler.go`
Added `RegisterWorkflowRoutes()` function to register Hatchet workflow endpoints:
- `POST /api/v1/hatchet/trigger` - Trigger workflow
- `GET /api/v1/hatchet/runs/:runId` - Get workflow run status
- `POST /api/v1/hatchet/runs/:runId/cancel` - Cancel workflow run
- `GET /api/v1/hatchet/runs` - List workflow runs (requires project_id query param)

#### `/backend/internal/handlers/chaos_handler.go`
Added `RegisterChaosRoutes()` function to register chaos engineering endpoints:
- `POST /api/v1/chaos/detect-zombies` - Detect zombie items
- `GET /api/v1/chaos/impact/:itemId` - Analyze impact of an item

### 2. Server Route Registration

#### `/backend/internal/server/server.go` (Lines 689-710)
Added route registrations after the Storage routes section:

```go
// Delegation client routes - AI, Spec Analytics, Execution, Workflow, Chaos
log.Println("🔌 Initializing Delegation Client routes...")

// AI routes
handlers.RegisterAIRoutes(api, s.infra)
log.Println("✅ AI routes registered")

// Spec Analytics routes
handlers.RegisterSpecAnalyticsRoutes(api, s.infra)
log.Println("✅ Spec Analytics routes registered")

// Execution routes
handlers.RegisterExecutionRoutes(api, s.infra)
log.Println("✅ Execution routes registered")

// Workflow routes (Hatchet)
handlers.RegisterWorkflowRoutes(api, s.infra)
log.Println("✅ Workflow routes registered")

// Chaos routes
handlers.RegisterChaosRoutes(api, s.infra)
log.Println("✅ Chaos routes registered")
```

## Complete API Endpoints

### AI Service (`/api/v1/ai`)
- `POST /stream-chat` - Stream AI chat responses (SSE)
- `POST /analyze` - Analyze text with AI

### Spec Analytics Service (`/api/v1/spec-analytics`)
- `POST /analyze` - Analyze specification
- `POST /batch-analyze` - Batch analyze specifications (max 100)
- `POST /validate-iso29148` - Validate ISO 29148 compliance
- `POST /ears-patterns` - Extract EARS patterns

### Execution Service (`/api/v1/execution`)
- `POST /run-tests` - Start test execution
- `GET /:executionId/status` - Get execution status
- `POST /:executionId/cancel` - Cancel execution
- `GET /:executionId/output` - Get execution output
- `GET /:executionId/recording` - Get execution recording

### Workflow Service (`/api/v1/hatchet`)
- `POST /trigger` - Trigger workflow
- `GET /runs/:runId` - Get workflow run status
- `POST /runs/:runId/cancel` - Cancel workflow run
- `GET /runs` - List workflow runs

### Chaos Service (`/api/v1/chaos`)
- `POST /detect-zombies` - Detect zombie items
- `GET /impact/:itemId` - Analyze impact

## Pattern Followed

All route registrations follow the established pattern:
1. Create a registration function `Register*Routes(e *echo.Group, infra *infrastructure.Infrastructure)`
2. Instantiate the handler with `New*Handler(infra)`
3. Create a sub-group with the service prefix
4. Register individual endpoints on the sub-group
5. Call the registration function in `server.go` passing `api` group and `s.infra`

## Verification

All routes are now properly wired and will:
1. Be accessible at their respective endpoints
2. Return proper responses instead of 404 errors
3. Use the delegation clients from the infrastructure layer
4. Support proper error handling and validation

## Next Steps

To test the routes:
1. Start the Go backend server
2. Verify routes in server logs (should see "✅ AI routes registered", etc.)
3. Test endpoints with curl or HTTP client
4. Verify proper integration with delegation clients

Example test:
```bash
# Test AI analyze endpoint
curl -X POST http://localhost:8080/api/v1/ai/analyze \
  -H "Content-Type: application/json" \
  -d '{
    "text": "This is a test requirement",
    "project_id": "test-project"
  }'
```
