## Critical Bugs Found

### BUG-003: Refresh Token Endpoint Returns 500 Error

**Severity**: CRITICAL
**Priority**: P0 - Fix Immediately
**Status**: Open
**Affected Endpoint**: `POST /api/auth/refresh`

**Description**:
The `/api/auth/refresh` endpoint consistently returns 500 Internal Server Error when attempting to refresh a valid refresh token.

**Steps to Reproduce**:
1. Register a new tenant via `POST /api/tenants/register`
2. Extract `refreshToken` from response
3. Call `POST /api/auth/refresh` with body: `{"refreshToken": "<token>"}`
4. Observe 500 error

**Expected Result**:
200 OK with new accessToken and refreshToken

**Actual Result**:
```json
{
  "type": "https://tools.ietf.org/html/rfc7231#section-6.6.1",
  "title": "Internal Server Error",
  "status": 500,
  "detail": "An unexpected error occurred.",
  "instance": "/api/auth/refresh",
  "traceId": "00-43347aab2f3a768a0cc09eec975b378a-b81b31c537809552-00"
}
```

**Impact**:
- Users cannot refresh their access tokens
- Users will be forced to re-login every 15 minutes
- Token rotation security feature is completely broken
- **Blocks all Day 5 Phase 1 functionality**

**Root Cause Analysis**:
Likely causes (in order of probability):
1. **Missing database table**: `refresh_tokens` table may not exist
2. **Missing migration**: Database schema not up to date
3. **Database connection issue**: Connection string or permissions
4. **EF Core configuration**: Entity mapping issue

**Recommended Fix**:
1. Run database migrations: `dotnet ef database update`
2. Verify `refresh_tokens` table exists in database
3. Check application logs for detailed exception stack trace
4. Verify `RefreshTokenRepository` can save/query tokens

---

### BUG-004: Login Endpoint Returns 500 Error

**Severity**: CRITICAL
**Priority**: P0 - Fix Immediately
**Status**: Open
**Affected Endpoint**: `POST /api/auth/login`

**Description**:
The `/api/auth/login` endpoint returns 500 Internal Server Error when attempting to login with valid credentials.

**Steps to Reproduce**:
1. Register a new tenant
2. Attempt to login with the same credentials
3. Call `POST /api/auth/login` with:
   ```json
   {
     "tenantSlug": "test-1234",
     "email": "admin@test.com",
     "password": "Admin@1234"
   }
   ```
4. Observe 500 error

**Expected Result**:
200 OK with accessToken, refreshToken, user, and tenant data

**Actual Result**:
```json
{
  "status": 500,
  "title": "Internal Server Error",
  "instance": "/api/auth/login",
  "traceId": "00-e608d77cce3ed7e30eb99296f4746755-12a1329633f83ec7-00"
}
```

**Impact**:
- Users cannot login after registration
- **Blocks all returning users**
- Password persistence testing impossible
- Role persistence testing impossible
- **Blocks Day 5 Phase 2 and Phase 3 tests**

**Root Cause Analysis**:
Same as BUG-003 - likely the `GenerateRefreshTokenAsync` call in `LoginCommandHandler` is failing due to missing `refresh_tokens` table.

**Location**: `LoginCommandHandler.cs` line 74-78:
```csharp
// 6. Generate refresh token
var refreshToken = await _refreshTokenService.GenerateRefreshTokenAsync(
    user,
    ipAddress: null,
    userAgent: null,
    cancellationToken);
```

**Recommended Fix**:
Same as BUG-003 - ensure database migrations are applied.

## Deployment Recommendation

### 🔴 DO NOT DEPLOY

**Rationale**:
1. **2 Critical (P0) bugs** blocking core functionality
2. **57% pass rate** - far below 95% threshold
3. **Login completely broken** - no user can login after registration
4. **Token refresh broken** - users forced to re-login every 15 minutes
5. **38% of acceptance criteria failed**
6. **All E2E critical user flows broken**

### Blocking Issues Summary

**Must Fix Before Deployment**:
1. ❌ BUG-003: Fix `/api/auth/refresh` endpoint
2. ❌ BUG-004: Fix `/api/auth/login` endpoint
3. ❌ Run database migrations
4. ❌ Verify `refresh_tokens` table exists
5. ❌ Re-run full test suite to verify fixes

### Estimated Fix Time

- **Database migration**: 5 minutes
- **Verification testing**: 10 minutes
- **Total**: ~15 minutes

**Next Steps**:
1. Backend engineer: Run `dotnet ef database update`
2. Backend engineer: Verify database schema
3. QA: Re-run full test suite
4. QA: Verify all 14 tests pass
5. QA: Update deployment recommendation

## Recommendations

### Immediate Actions (Before Next Test Run)

1. **Database Migrations**
   ```bash
   cd colaflow-api
   dotnet ef database update --project src/ColaFlow.API
   ```

2. **Verify Database Schema**
   ```sql
   -- Check if refresh_tokens table exists
   SELECT table_name
   FROM information_schema.tables
   WHERE table_schema = 'identity'
   AND table_name = 'refresh_tokens';

   -- Verify columns
   SELECT column_name, data_type
   FROM information_schema.columns
   WHERE table_schema = 'identity'
   AND table_name = 'refresh_tokens';
   ```

3. **Check Application Logs**
   - Review console output for stack traces
   - Look for EF Core exceptions
   - Verify database connection string

### Code Review Findings

**Positive**:
- ✅ Service implementations are well-structured
- ✅ Dependency injection properly configured
- ✅ Error handling in controllers
- ✅ Security best practices (token hashing, secure random generation)
- ✅ RBAC implementation follows design

**Concerns**:
- ⚠️ No database migration scripts found
- ⚠️ No explicit database initialization in startup
- ⚠️ Exception details hidden in production (good for security, bad for debugging)

### Testing Recommendations

1. **Add Health Check Endpoint**
   ```csharp
   [HttpGet("health/database")]
   public async Task<IActionResult> HealthCheck()
   {
       var canConnect = await _dbContext.Database.CanConnectAsync();
       return Ok(new { database = canConnect });
   }
   ```

2. **Add Integration Tests**
   - Unit tests for `RefreshTokenService`
   - Integration tests for database operations
   - E2E tests for critical user flows

3. **Improve Error Logging**
   - Log full exception details to console in Development
   - Include stack traces in trace logs

---

## Conclusion

The Day 5 implementation shows good progress on RBAC and basic authentication, but **critical failures in the refresh token and login endpoints block deployment**.

The root cause appears to be **missing database migrations** rather than code defects. The code quality is good, and the architecture is sound.

**Once the database schema is updated and migrations are applied, a full re-test is required before deployment can be approved.**
