+
+## 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

+  }
+```
+
+### Sample Successful Test
+
+**Test**: Register Tenant + Verify Role
+```powershell
+# Request
+POST http://localhost:5167/api/tenants/register
+{
+  "tenantName": "RBAC Test Corp",
+  "tenantSlug": "rbac-8945",
+  "subscriptionPlan": "Professional",
+  "adminEmail": "rbac@test.com",
+  "adminPassword": "Admin@1234",
+  "adminFullName": "RBAC Admin"
+}
+
+# Response
+200 OK
+{
+  "accessToken": "eyJhbGciOiJIUzI1NiIs...",
+  "refreshToken": "CscU32NXsuAkYrDovkdm...",
+  "user": { "id": "...", "email": "rbac@test.com" },
+  "tenant": { "id": "...", "slug": "rbac-8945" }
+}
+
+# Verify Role
+GET http://localhost:5167/api/auth/me
+Authorization: Bearer <accessToken>
+
+# Response
+200 OK
+{
+  "userId": "...",
+  "tenantId": "...",
+  "email": "rbac@test.com",
+  "tenantRole": "TenantOwner",  ✅
+  "role": "TenantOwner",        ✅
+  "claims": [...]
+}
+```
+
+---
+
+## 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.**
