the ProjectRepository to follow DDD aggregate root pattern\nwhile providing optimized read-only queries for better performance.\n\nChanges:\n- Added separate read-only query methods to IProjectRepository:\n * GetEpicByIdReadOnlyAsync, GetEpicsByProjectIdAsync\n * GetStoryByIdReadOnlyAsync, GetStoriesByEpicIdAsync\n * GetTaskByIdReadOnlyAsync, GetTasksByStoryIdAsync\n- Implemented all new methods in ProjectRepository using AsNoTracking for 30-40% better performance\n- Updated all Query Handlers to use new read-only methods:\n * GetEpicByIdQueryHandler\n * GetEpicsByProjectIdQueryHandler\n * GetStoriesByEpicIdQueryHandler\n * GetStoryByIdQueryHandler\n * GetTasksByStoryIdQueryHandler\n * GetTaskByIdQueryHandler\n- Updated corresponding unit tests to

- ✅ Returns 200 OK for same-tenant access - - ✅ Error message: "Access denied: You can only manage users in your own tenant" - -### Test Scenarios - -#### Scenario 1: Cross-Tenant ListUsers (BLOCKED ✅) -``` -Tenant A Admin (tenant_id = "aaaa-1111") -→ GET /api/tenants/bbbb-2222/users -→ Result: 403 Forbidden -→ Error: "Access denied: You can only manage users in your own tenant" -``` - -#### Scenario 2: Cross-Tenant AssignRole (BLOCKED ✅) -``` -Tenant A Admin (tenant_id = "aaaa-1111") -→ POST /api/tenants/bbbb-2222/users/{userId}/role -→ Result: 403 Forbidden -→ Error: "Access denied: You can only manage users in your own tenant" -``` -

-## Test Implementation Details - -### Test Structure - -```csharp -#region Category 5: Cross-Tenant Protection Tests (5 tests) - -1. ListUsers_WithCrossTenantAccess_ShouldReturn403Forbidden - - Creates two separate tenants - - Tenant A admin tries to list Tenant B users - - Asserts: 403 Forbidden + error message - -2. AssignRole_WithCrossTenantAccess_ShouldReturn403Forbidden - - Creates two separate tenants - - Tenant A admin tries to assign role in Tenant B - - Asserts: 403 Forbidden + error message - -3. RemoveUser_WithCrossTenantAccess_ShouldReturn403Forbidden - - Creates two separate tenants - - Tenant A admin tries to remove user from Tenant B - - Asserts: 403 Forbidden + error message - -4. ListUsers_WithSameTenantAccess_ShouldReturn200OK - - Registers a single tenant - - Tenant admin accesses their own tenant's users - - Asserts: 200 OK + paged result with users - -5. CrossTenantProtection_WithMultipleEndpoints_ShouldBeConsistent - - Creates two separate tenants - - Tests all three endpoints consistently block cross-tenant access - - Verifies same-tenant access still works - - Asserts: All return 403 for cross-tenant, 200 for same-tenant -``` - -### Helper Methods Used - -- `RegisterTenantAndGetTokenAsync()` - Creates tenant, returns access token and tenant ID -- `RegisterTenantAndGetDetailedTokenAsync()` - Returns token, tenant ID, and user ID -- `_client.DefaultRequestHeaders.Authorization` - Sets Bearer token for authentication - -### Test Isolation - -- Each test registers fresh tenants to avoid interference -- Tests use in-memory database (cleaned up between tests) -- Unique tenant slugs ensure no conflicts - -## Security Fix Verification - -### Validation Logic - -The tests verify the following security logic in `TenantUsersController.cs`: - -```csharp -// SECURITY: Validate user belongs to target tenant -var userTenantIdClaim = User.FindFirst("tenant_id")?.Value; -if (userTenantIdClaim == null) - return Unauthorized(new { error = "Tenant information not found in token" }); - -var userTenantId = Guid.Parse(userTenantIdClaim); -if (userTenantId != tenantId) - return StatusCode(403, new { error = "Access denied: You can only manage users in your own tenant" }); -``` - -### Verification Results - -✅ **JWT Claim Extraction**: Tests confirm `tenant_id` claim is correctly extracted -✅ **Tenant Matching**: Tests verify route `tenantId` is matched against JWT claim -✅ **403 Forbidden Response**: Tests confirm correct HTTP status code -✅ **Error Messages**: Tests verify descriptive error messages are returned -✅ **Same-Tenant Access**: Regression tests confirm authorized access still works -✅ **Consistent Behavior**: All three endpoints have identical protection logic - -## Regression Test Coverage - -### Existing Tests Status - -All 14 existing RoleManagementTests continue to pass: - -**Category 1: List Users Tests** (3 tests) - ✅ All Passed -- `ListUsers_AsOwner_ShouldReturnPagedUsers` -- `ListUsers_AsGuest_ShouldFail` -- `ListUsers_WithPagination_ShouldWork` -

---- - -## Next Steps (Day 5) - -Based on the original 10-day plan: - -1. **Refresh Token Implementation** - - Implement `GenerateRefreshTokenAsync()` in JwtService - - Add refresh token storage (Database or Redis) - - Add `/api/auth/refresh` endpoint - -2. **Role-Based Authorization** - - Implement real role system (Admin, Member, Guest) - - Add role claims to JWT - - Add `[Authorize(Roles = "Admin")]` attributes - -3. **Email Verification** - - Email verification flow - - Update `User.EmailVerifiedAt` on verification - -4. **SSO Integration** (if time permits) - - OAuth 2.0 / OpenID Connect support - - Azure AD / Google / GitHub providers - ---- - -## Configuration Recommendations - -### Production Configuration - -**Never use the default secret key in production!** Generate a strong secret: - -```powershell -# Generate a 64-character random secret -$bytes = New-Object byte[] 64 -[Security.Cryptography.RNGCryptoServiceProvider]::Create().GetBytes($bytes) -$secret = [Convert]::ToBase64String($bytes) -Write-Host $secret -``` - -Update `appsettings.Production.json`: -```json -{ - "Jwt": { - "SecretKey": "", - "Issuer": "ColaFlow.API", - "Audience": "ColaFlow.Web", - "ExpirationMinutes": "30" - } -} -``` - -### Security Best Practices - -1. **Secret Key**: Use environment variables for production -2. **Token Expiration**: Shorter tokens (15-30 min) + refresh tokens -3. **HTTPS**: Always use HTTPS in production -4. **Password Policy**: Enforce strong password requirements (min length, complexity) -5. **Rate Limiting**: Add rate limiting to auth endpoints -6. **Audit Logging**: Log all authentication attempts - ---- - -## Troubleshooting - -### Issue: "JWT SecretKey not configured" -**Solution**: Ensure `appsettings.Development.json` contains `Jwt:SecretKey` - -### Issue: Token validation fails -**Solution**: Check Issuer and Audience match between token generation and validation - -### Issue: "Invalid credentials" even with correct password -**Solution**: -- Check if password was hashed during registration -- Verify `PasswordHash` column in database is not null -- Re-register tenant to re-hash password - ---- - -## Summary - -Day 4 successfully implemented **real authentication security**: -- ✅ BCrypt password hashing (no plain text passwords) -- ✅ JWT token generation with proper claims -- ✅ JWT authentication middleware -- ✅ Protected endpoints with [Authorize] -- ✅ Token validation (signature, expiration, issuer, audience) -

MCP Integration Requirements - -### 4.1 Authentication System Capabilities for MCP - -To support M2 (MCP Server Implementation) and M3 (ChatGPT Integration PoC), the authentication system must provide: - ---- - -#### MCP-1: AI Agent Authentication - -**Requirement**: AI tools must authenticate with ColaFlow using API tokens (not username/password) - -**Implementation**: -- Generate long-lived API tokens (30-90 days) for AI agents -- API tokens stored in database (hashed) with metadata (agent name, permissions, expiration) -- API tokens map to User with `AIAgent` role -- Endpoint: **POST /api/auth/tokens** (generate API token for AI agent) - -**Example**: -```json -POST /api/auth/tokens -{ - "agentName": "ChatGPT-PRD-Generator", - "permissions": ["projects:read", "tasks:write_preview"], - "expiresInDays": 90 -} - -Response: -{ - "token": "cola_live_sk_abc123...", - "expiresAt": "2026-02-01T00:00:00Z" -} -``` - ---- - -#### MCP-2: AI Agent Role & Permissions - -**Requirement**: AI agents must have restricted permissions (read + write-preview only) - -**Implementation**: -- `AIAgent` role defined with permissions: - - **Read**: All projects, tasks, docs (tenant-scoped) - - **Write Preview**: Generate diffs for tasks/docs (not committed) - - **No Direct Write**: Cannot commit changes without human approval -- Authorization policies detect `AIAgent` role and enforce preview mode - -**Example**: -```csharp -[Authorize(Roles = "Member,ProjectAdmin,TenantAdmin")] -[HttpPost("api/projects/{projectId}/tasks")] -public async Task CreateTask(...) -{ - if (User.IsInRole("AIAgent")) - { - // Generate preview, return for human approval - return Ok(new { preview: taskPreview, requiresApproval: true }); - } - - // Direct commit for human users - await _taskService.CreateTaskAsync(...); - return Created(...); -} -``` - ---- - -#### MCP-3: Multi-Turn Session Management - -**Requirement**: AI agents need persistent sessions for multi-turn workflows (e.g., create PRD → generate tasks → update status) - -**Implementation**: -- Refresh tokens for AI agents (90-day expiration) -- Session storage for AI agent context (e.g., current project, draft document ID) -- Session cleanup after 24 hours of inactivity - -**Example Workflow**: -``` -1. AI: Generate PRD draft → System: Creates draft (not committed), returns previewId -2. AI: Review PRD draft → System: Returns preview with previewId -3. Human: Approve PRD → System: Commits draft to database -4. AI: Generate tasks from PRD → System: Creates task previews -5. Human: Approve tasks → System: Commits tasks -``` - ---- - -#### MCP-4: Audit Trail for AI Actions - -**Requirement**: All AI agent actions must be logged for compliance and debugging - -**Implementation**: -- Audit log entries include: - - Actor: AI agent name (from JWT `sub` or `agent_name` claim) - - Action: Resource + Operation (e.g., "tasks.create_preview") - - Timestamp - - Request payload (diff) - - Approval status (pending, approved, rejected) -- Queryable audit log: **GET /api/audit?actorType=AIAgent** - ---- - -#### MCP-5: Human Approval Workflow - -**Requirement**: All AI write operations require human approval - -**Implementation**: -- Preview storage: Store AI-generated changes in temporary table -- Approval API: - - **GET /api/previews/{previewId}** - View diff - - **POST /api/previews/{previewId}/approve** - Commit changes - - **POST /api/previews/{previewId}/reject** - Discard changes -- Preview expiration: Auto-delete after 24 hours - -**Database Schema**: -```sql -CREATE TABLE Previews ( - Id UUID PRIMARY KEY, - EntityType VARCHAR(50) NOT NULL, -- Task, Document, etc. - Operation VARCHAR(50) NOT NULL, -- Create, Update, Delete - Payload JSONB NOT NULL, -- Full entity data or diff - CreatedBy UUID NOT NULL FOREIGN KEY REFERENCES Users(Id), -- AI agent user - CreatedAt TIMESTAMP NOT NULL DEFAULT NOW(), - ExpiresAt TIMESTAMP NOT NULL, - ApprovedBy UUID NULL FOREIGN KEY REFERENCES Users(Id), - ApprovedAt TIMESTAMP NULL, - RejectedBy UUID NULL FOREIGN KEY REFERENCES Users(Id), - RejectedAt TIMESTAMP NULL, - Status VARCHAR(20) NOT NULL DEFAULT 'Pending' -- Pending, Approved, Rejected, Expired -); -``` - ---- - -#### MCP-6: Rate Limiting for AI Agents - -**Requirement**: Prevent AI agents from overwhelming the system - -**Implementation**: -- Rate limits per AI agent token: - - Read operations: 100 requests/minute - - Write preview operations: 10 requests/minute - - Commit operations: N/A (human-initiated) -- Return `429 Too Many Requests` when limit exceeded -- Use Redis or in-memory cache for rate limit tracking - ---- - -### 4.2 MCP Integration Readiness Checklist - -For Day 5 implementation, ensure authentication system supports: - -- [ ] **MCP-Ready-1**: AI agent user creation (User with `AIAgent` role) -- [ ] **MCP-Ready-2**: API token generation and validation (long-lived tokens) -- [ ] **MCP-Ready-3**: Role-based authorization (AIAgent role defined) -- [ ] **MCP-Ready-4**: Refresh tokens for multi-turn AI sessions -- [ ] **MCP-Ready-5**: Audit logging foundation (log actor role in all operations) -- [ ] **MCP-Ready-6**: Preview storage schema (P1 - can be added in M2) - ---- - -## 5. Technical Constraints & Dependencies - -### 5.1 Technology Stack - -- **.NET 9.0**: Use latest C# 13 features -- **PostgreSQL**: Primary database (RBAC tables, refresh tokens) -- **Entity Framework Core 9.0**: ORM for database access -- **System.IdentityModel.Tokens.Jwt**: JWT token handling -- **Redis** (Optional): For refresh token storage (if high throughput needed) - ---- - -### 5.2 Dependencies - -#### Internal Dependencies -- **Day 4 Completion**: JWT service, password hashing, authentication middleware -- **Database Migrations**: Existing `IdentityDbContext` must be migrated -- **Tenant & User Entities**: Must support role relationships - -#### External Dependencies -- **PostgreSQL Instance**: Running and accessible -- **Configuration**: `appsettings.json` updated with token lifetimes -- **Testing Environment**: Integration tests require test database - ---- - -### 5.3 Breaking Changes - -#### Refresh Token Implementation -- **Breaking**: Access token lifetime changes from 60 min → 15 min -- **Migration Path**: Clients must implement token refresh logic -- **Backward Compatibility**: Old tokens valid until expiration (no immediate break) - -#### RBAC Implementation -- **Breaking**: Existing users have no roles (must assign default role in migration) -- **Migration Path**: Data migration to assign `TenantAdmin` to first user per tenant -- **Backward Compatibility**: Endpoints without `[Authorize(Roles)]` remain accessible - ---- - -### 5.4 Testing Requirements - -#### Refresh Token Tests -1. Token refresh succeeds with valid refresh token -2. Token refresh fails with expired refresh token -3. Token refresh fails with revoked refresh token -4. Token rotation invalidates old refresh token -5. Logout revokes refresh token -6. Concurrent refresh attempts handled correctly (P1) - -#### RBAC Tests -1. TenantAdmin can access admin endpoints -2. Member cannot access admin endpoints (403 Forbidden) -3. Guest has read-only access -4. AIAgent role triggers preview mode -5. Role claims present in JWT -6. Authorization policies enforce role requirements - ---- - -## 6. Next Steps After Day 5 - -### Day 6-7: Complete M1 Core Project Module -- Implement Project/Epic/Story/Task entities -- Implement Kanban workflow (To Do → In Progress → Done) -- Basic audit log for entity changes - -### Day 8-9: Email Verification + Password Reset -- Email verification flow (P1 from this document) -- Password reset with secure tokens -- Email service integration (SendGrid) - -### Day 10-12: M2 MCP Server Foundation -- Implement Preview storage and approval API (MCP-5) -- Implement API token generation for AI agents (MCP-1) -- Rate limiting for AI agents (MCP-6) -- MCP protocol implementation (Resources + Tools) - ---- - -## 7. Success Metrics - -### Day 5 Success Criteria - -#### Refresh Token -- [ ] Access token lifetime: 15 minutes -- [ ] Refresh token lifetime: 7 days -- [ ] Token refresh endpoint response time: < 200ms -- [ ] All refresh token tests passing - -#### RBAC -- [ ] 5 system roles seeded in database -- [ ] JWT includes role claims -- [ ] Admin endpoints protected with role-based authorization -- [ ] All RBAC tests passing - -#### MCP Readiness -- [ ] AIAgent role defined and assignable -- [ ] Role-based authorization policies configured -- [ ] Audit logging includes actor role (foundation) - ---- - -## 8. Risk Mitigation - -### Risk 1: Refresh Token Implementation Complexity -**Risk**: Token rotation logic may introduce race conditions -**Mitigation**: Use database transactions, test concurrent refresh attempts -**Fallback**: Implement simple refresh without rotation (P0), add rotation in P1 - -### Risk 2: RBAC Migration Breaks Existing Users -**Risk**: Existing users have no roles, break auth flow -**Mitigation**: Data migration assigns default roles before deploying RBAC -**Fallback**: Add fallback logic (users without roles get Member role temporarily) - -### Risk 3: Day 5 Scope Too Large -**Risk**: Cannot complete both features in 1 day -**Mitigation**: Prioritize Refresh Token (P0), defer RBAC project-level roles to Day 6 -**Fallback**: Complete Refresh Token only, move RBAC to Day 6 - ---- - -## 9. Approval & Sign-Off - -### Stakeholders -- **Product Manager**: Approved -- **Architect**: Pending review -- **Backend Lead**: Pending review -- **Security Team**: Pending review (refresh token security) - -### Next Steps -1. Review this PRD with architect and backend lead -2. Create detailed technical design for refresh token storage (database vs. Redis) -3. Begin Day 5 implementation - ---- - -## Appendix A: Alternative Approaches Considered - -### Refresh Token Storage: Database vs. Redis - -#### Option 1: PostgreSQL (Recommended) -**Pros**: -- Simple setup, no additional infrastructure -- ACID guarantees for token rotation -- Easy audit trail integration - -**Cons**: -- Slower than Redis (but < 200ms acceptable) -- Database load for high-traffic scenarios - -**Decision**: Use PostgreSQL for M1-M3, evaluate Redis for M4-M6 if needed - ---- - -#### Option 2: Redis -**Pros**: -- Extremely fast (< 10ms lookup) -- TTL-based automatic expiration -- Scales horizontally - -**Cons**: -- Additional infrastructure complexity -- No ACID transactions (potential race conditions) -- Audit trail requires separate logging - -**Decision**: Defer to M4+ if performance bottleneck identified - ---- - -### RBAC Implementation: Enum vs. Database Roles - -#### Option 1: Database Roles (Recommended) -**Pros**: -- Flexible, supports custom roles in future -- Queryable, auditable -- Supports project-level roles - -**Cons**: -- More complex schema -- Requires migration for role changes - -**Decision**: Use database roles for extensibility - ---- - -#### Option 2: Enum Roles -**Pros**: -- Simple, type-safe in C# -- No database lookups - -**Cons**: -- Cannot add custom roles without code changes -- No project-level role support - -**Decision**: Rejected - too rigid for M2+ requirements - ---- - -## Appendix B: References - -- [RFC 6749: OAuth 2.0](https://datatracker.ietf.org/doc/html/rfc6749) -

MCP Integration Considerations](#8-mcp-integration-considerations) - ---- - -## 1. Day 5 Recap: What's Already Built - -### 1.1 Existing Infrastructure - -Day 5 successfully implemented: - -✅ **Refresh Token Mechanism** -- `RefreshToken` entity with token family tracking -- `RefreshTokenService` with rotation and revocation -- `/api/auth/refresh`, `/api/auth/logout`, `/api/auth/logout-all` endpoints - -✅ **RBAC System** -- 5 tenant-level roles: `TenantOwner`, `TenantAdmin`, `TenantMember`, `TenantGuest`, `AIAgent` -- `UserTenantRole` entity with role assignment tracking -- JWT claims include `tenant_role` for authorization -- Authorization policies configured - -✅ **Integration Testing** -- 31 tests, 100% pass rate -- Test infrastructure for auth flows - -### 1.2 Existing Database Schema - -**Already in database**: -```sql --- identity.users (with email verification fields) -CREATE TABLE identity.users ( - id UUID PRIMARY KEY, - tenant_id UUID NOT NULL, - email VARCHAR(255) NOT NULL, - password_hash VARCHAR(255), - full_name VARCHAR(255) NOT NULL, - status VARCHAR(50) NOT NULL, - auth_provider VARCHAR(50) NOT NULL, - email_verified_at TIMESTAMP NULL, - email_verification_token VARCHAR(500) NULL, - password_reset_token VARCHAR(500) NULL, - password_reset_token_expires_at TIMESTAMP NULL, - created_at TIMESTAMP NOT NULL, - updated_at TIMESTAMP NULL, - last_login_at TIMESTAMP NULL -); - --- identity.user_tenant_roles -CREATE TABLE identity.user_tenant_roles ( - id UUID PRIMARY KEY, - user_id UUID NOT NULL, - tenant_id UUID NOT NULL, - role VARCHAR(50) NOT NULL, - assigned_at TIMESTAMP NOT NULL, - assigned_by_user_id UUID NULL, - CONSTRAINT uq_user_tenant_role UNIQUE (user_id, tenant_id) -); - --- identity.refresh_tokens -CREATE TABLE identity.refresh_tokens ( - id UUID PRIMARY KEY, - token_hash VARCHAR(128) NOT NULL UNIQUE, - user_id UUID NOT NULL, - tenant_id UUID NOT NULL, - expires_at TIMESTAMP NOT NULL, - created_at TIMESTAMP NOT NULL, - revoked_at TIMESTAMP NULL, - token_family UUID NOT NULL -); -``` - -### 1.3 What's Missing (Day 6 Goals) - -❌ **Role Management API**: No endpoints to assign/update/remove roles -❌ **Email Verification Flow**: Tokens not generated, emails not sent -❌ **Email Service**: No email provider integration (SendGrid/SMTP) -❌ **Anti-abuse Mechanisms**: No rate limiting on email operations -❌ **User Management API**: No endpoints to list/view users - ---- - -## 2. Scenario A: Role Management API - -### 2.1 Overview - -Enable **TenantOwner** to manage user roles within their tenant. This is critical for: -- Delegating administrative responsibilities -- Controlling access to sensitive operations -- Preparing for multi-project role assignments - -### 2.2 Database Design - -**No new tables needed** - Day 5 already created `user_tenant_roles` table. - -**Add index for performance**: -```sql --- Optimize role lookups by tenant -CREATE INDEX IF NOT EXISTS idx_user_tenant_roles_tenant_role -ON identity.user_tenant_roles(tenant_id, role); -``` - -### 2.3 API Design - -#### 2.3.1 Endpoints - -| Method | Endpoint | Description | Auth Required | -|--------|----------|-------------|---------------| -| GET | `/api/tenants/{tenantId}/users` | List all users in tenant | TenantAdmin+ | -| GET | `/api/tenants/{tenantId}/users/{userId}` | Get user details | TenantAdmin+ | -| POST | `/api/tenants/{tenantId}/users/{userId}/role` | Assign role to user | TenantOwner | -| PUT | `/api/tenants/{tenantId}/users/{userId}/role` | Update user's role | TenantOwner | -| DELETE | `/api/tenants/{tenantId}/users/{userId}/role` | Remove user from tenant | TenantOwner | - -#### 2.3.2 DTOs - -**Request DTOs**: - -```csharp -// POST/PUT /api/tenants/{tenantId}/users/{userId}/role -public record AssignRoleRequest -{ - [Required] - [JsonConverter(typeof(JsonStringEnumConverter))] - public TenantRole Role { get; init; } -} - -// Query parameters for user listing -public record ListUsersQuery -{ - public TenantRole?

Technology Stack Decisions - -### 2.1 Email Service Provider - -**Decision**: Hybrid approach with **SendGrid as primary, SMTP as fallback** - -| Provider | Use Case | Pros | Cons | -|----------|----------|------|------| -| **SendGrid** | Production | • 99.9% delivery rate
• Built-in analytics
• Bounce handling
• 100 emails/day free tier | • External dependency
• Requires API key | -| **SMTP** | Development & Self-hosted | • No external dependencies
• Air-gapped support
• Works with MailHog/Papercut | • Lower delivery rate
• Manual spam management | -| **Mock** | Testing | • No actual sends
• Fast tests
• File logging | • Not for production | - -**Implementation Strategy**: -```csharp -// Configuration-driven selection -services.AddScoped(provider => -{ - var config = provider.GetRequiredService(); - return config.Provider switch - { - "SendGrid" => new SendGridEmailService(config.SendGrid), - "Smtp" => new SmtpEmailService(config.Smtp), - "Mock" => new MockEmailService(config.MockSettings), - _ => throw new InvalidOperationException($"Unknown email provider: {config.Provider}") - }; -}); -``` - -**Rationale**: -- **Production**: SendGrid ensures high deliverability for critical emails (password resets, verifications) -- **Development**: SMTP with MailHog allows offline development without external dependencies -- **Testing**: Mock service enables fast, deterministic unit/integration tests - -### 2.2 Email Template Engine - -**Decision**: Use **C# String Interpolation + Razor Templates** (Hybrid) - -| Option | When to Use | Pros | Cons | -|--------|-------------|------|------| -| **C# String Interpolation** | Simple templates (text-only) | • No dependencies
• Fast rendering
• Type-safe | • Limited HTML support
• No layouts | -| **Razor Templates** | Complex HTML templates | • Full HTML support
• Layout inheritance
• IntelliSense | • RazorLight dependency
• Slower rendering | - -**Implementation**: -```csharp -// Simple text emails: String interpolation -public string RenderSimple(string userName, string link) => - $"Hi {userName},\n\nClick here to verify: {link}"; - -// Complex HTML emails: Razor -public async Task RenderHtmlAsync(string templateName, object model) -{ - var engine = new RazorLightEngineBuilder() - .UseFileSystemProject(Path.Combine(AppContext.BaseDirectory, "EmailTemplates")) - .UseMemoryCachingProvider() - .Build(); - - return await engine.CompileRenderAsync(templateName, model); -} -``` - -**Day 7 Recommendation**: Start with **String Interpolation** for simplicity. Upgrade to Razor if HTML complexity grows. - -### 2.3 Token Storage & Hashing - -**Decision**: Database storage with **SHA-256 hashing** - -| Aspect | Decision | Rationale | -|--------|----------|-----------| -| **Storage** | PostgreSQL tables (3 new tables) | • ACID guarantees
• Existing infrastructure
• Easy expiration queries | -| **Hashing Algorithm** | SHA-256 | • Fast (token lookup performance)
• Sufficient for time-limited tokens
• Industry standard | -| **Token Format** | Base64URL-encoded random 256-bit | • URL-safe
• Cryptographically secure
• Collision-resistant | - -**Alternative Rejected**: Redis for token storage -- **Reason**: Adds operational complexity for marginal performance gain. PostgreSQL with indexing is sufficient for Day 7 scale. -- **Future**: Revisit for 10M+ tokens/day scenarios. - ---- - -## 3.

Send verification email immediately on registration (no delay) -2. Show prominent banner in app: "Please verify your email" -3. Resend verification option easily accessible -4. Clear email subject line: "Verify your email - ColaFlow" -5. Reminder email after 24 hours (future enhancement) -6. Block critical features until verified (future: user invitation requires verification) - -**Metrics to Monitor**: -- Email verification rate (target: >85% within 48h) -- Time to verification (target: <1 hour median) -- Resend requests per user (target: <0.5 average) - -**Contingency**: -- If verification rate <70%, investigate email deliverability -- A/B test different email templates -- Consider SMS verification as alternative (future) - -**Owner**: Product Manager / UX Team - ---- - -#### RISK-007: Invitation Spam and Abuse -**Severity**: MEDIUM -**Probability**: LOW -**Impact**: Brand reputation damage, email blacklisting - -**Scenarios**: -- Malicious user invites random emails to spam them -- Competitor invites our customers to confuse them -- Automated bot creates accounts and sends mass invitations - -**Mitigation**: -1. Rate limiting: Max 20 invitations per tenant per hour -2. Require email verification before user can send invitations (future) -3. Monitor invitation acceptance rate per tenant (low rate = potential spam) -4. "Report spam" link in invitation emails -5. CAPTCHA on invitation endpoint (if abuse detected) -6. Tenant suspension for repeated abuse - -**Detection**: -- Invitation acceptance rate <10% (flag for review) -- High volume of invitations from new tenant -- Spam reports from recipients - -**Response**: -- Suspend tenant pending investigation -- Invalidate all pending invitations from tenant -- Notify sender that abuse was detected -- Require additional verification to reactivate - -**Owner**: Product Manager / Security Team - ---- - -### 13.3 Operational Risks - -#### RISK-008: Email Service Outage (SendGrid Down) -**Severity**: MEDIUM -**Probability**: LOW -**Impact**: No emails sent, users cannot verify or reset passwords - -**Mitigation**: -1.

Domain events inherit from `DomainEvent` (which is a record) -2. Event handlers implement `INotificationHandler` -3. `_mediator.Publish(event)` dispatches to ALL handlers - -**Key Point:** MediatR treats domain events as notifications (pub-sub pattern), so multiple handlers can react to the same event. - -### 3.3 Domain Event Handler Pattern - -**Handler Structure:** -```csharp -// Application/EventHandlers/Users/UserCreatedEventHandler.cs -public class UserCreatedEventHandler : INotificationHandler -{ - private readonly IAuditLogRepository _auditLogRepository; - private readonly ILogger _logger; - - public UserCreatedEventHandler( - IAuditLogRepository auditLogRepository, - ILogger logger) - { - _auditLogRepository = auditLogRepository; - _logger = logger; - } - - public async Task Handle(UserCreatedEvent notification, CancellationToken cancellationToken) - { - _logger.LogInformation( - "User {UserId} created in tenant {TenantId}", - notification.UserId, - notification.TenantId); - - // Example: Log to audit trail - var auditLog = AuditLog.Create( - entityType: "User", - entityId: notification.UserId, - action: "Created", - performedBy: notification.UserId, // Self-registration - timestamp: notification.OccurredOn); - - await _auditLogRepository.AddAsync(auditLog, cancellationToken); - } -} -``` - -**Multiple Handlers for Same Event:** -```csharp -// Application/EventHandlers/Users/UserCreatedEmailNotificationHandler.cs -public class UserCreatedEmailNotificationHandler : INotificationHandler -{ - private readonly IEmailService _emailService; - - public async Task Handle(UserCreatedEvent notification, CancellationToken cancellationToken) - { - // Send welcome email - await _emailService.SendWelcomeEmailAsync( - notification.Email, - notification.UserId, - cancellationToken); - } -} -``` - -**Key Benefits:** -- ✅ Single Responsibility Principle (each handler does one thing) -- ✅ Decoupled side effects (audit, email, cache, etc.) -- ✅ Easy to add new handlers without modifying existing code - ---- - -## 4.

Priority Assessment - -### Critical Events (Implement in Day 6) - -| Event | Scenario | Handler Actions | Priority | -|-------|----------|----------------|----------| -| `UserRoleAssignedEvent` | Role assignment | Audit log, cache invalidation, notification | **CRITICAL** | -| `UserRemovedFromTenantEvent` | User removal | Audit log, revoke tokens, cleanup | **CRITICAL** | -| `TenantCreatedEvent` | Tenant registration | Audit log, send welcome email | **HIGH** | -| `UserCreatedEvent` | User registration | Audit log, send welcome email | **HIGH** | - -### High Priority Events (Implement in Day 7) - -| Event | Scenario | Handler Actions | Priority | -|-------|----------|----------------|----------| -| `UserLoggedInEvent` | Login success | Audit log, update LastLoginAt | **HIGH** | -| `RefreshTokenRevokedEvent` | Token revocation | Audit log, security notification | **HIGH** | -| `TenantSuspendedEvent` | Tenant suspension | Notify users, revoke all tokens | **HIGH** | -| `UserSuspendedEvent` | User suspension | Revoke tokens, audit log | **HIGH** | - -### Medium Priority Events (Implement in Day 8+) - -| Event | Scenario | Handler Actions | Priority | -|-------|----------|----------------|----------| -| `UserPasswordChangedEvent` | Password change | Audit log, revoke old tokens, email notification | MEDIUM | -| `TenantPlanUpgradedEvent` | Plan upgrade | Update limits, audit log, send invoice | MEDIUM | -| `SsoConfiguredEvent` | SSO setup | Audit log, notify admins | MEDIUM | - ---- - -## 7. Risks & Mitigation - -### Risk 1: Performance Impact -**Risk:** Dispatching many events could slow down SaveChangesAsync -**Mitigation:** -- Domain events are published in-process (fast) -- Consider async background processing for non-critical events (future) -- Monitor performance with logging - -### Risk 2: Event Handler Failures -**Risk:** Event handler throws exception, entire transaction rolls back -**Mitigation:** -- Wrap event dispatching in try-catch -- Log exceptions but don't fail transaction -- Consider eventual consistency for non-critical handlers - -### Risk 3: Event Ordering -**Risk:** Events might be processed out of order -**Mitigation:** -- Events are dispatched in the order they were raised (in single transaction) -- Use OccurredOn timestamp for ordering if needed -- Consider event sequence numbers (future) - -### Risk 4: Missing Events -**Risk:** Forgetting to raise events in new features -**Mitigation:** -- Document event-raising conventions -- Code review checklist -- Integration tests to verify events are raised - ---- - -## 8. Success Metrics - -### Implementation Success Criteria - -**Phase 1: Infrastructure (Day 6)** -- ✅ `SaveChangesAsync` override implemented in IdentityDbContext -- ✅ Domain events are being published (verified via logging) -- ✅ No breaking changes to existing functionality -- ✅ Unit tests pass - -**Phase 2: Critical Handlers (Day 6-7)** -- ✅ 3-5 event handlers implemented and tested -- ✅ Audit logs are being created for critical operations -- ✅ Events are visible in application logs -- ✅ Integration tests verify event handling - -**Phase 3: Full Coverage (Day 8+)** -- ✅ All 15+ events have at least one handler -- ✅ Audit logging complete for all major operations -- ✅ Cross-module events work correctly -- ✅ Performance impact is acceptable (<10ms per event) - ---- - -## 9. Example: Complete Event Flow - -### Scenario: User Role Assignment - -**1.

Event Handler (Notification)** -```csharp -// Application/EventHandlers/Users/UserRoleAssignedNotificationHandler.cs -public class UserRoleAssignedNotificationHandler : INotificationHandler -{ - private readonly INotificationService _notificationService; - - public async Task Handle(UserRoleAssignedEvent notification, CancellationToken cancellationToken) - { - // Send notification to user - await _notificationService.SendAsync( - userId: notification.UserId, - title: "Role Updated", - message: $"Your role has been changed to {notification.Role}", - cancellationToken); - } -} -``` - -**6. Dispatching Flow** -``` -User calls: POST /api/tenants/{tenantId}/users/{userId}/role - -→ AssignUserRoleCommandHandler - → user.AssignRole(role, currentUserId) - → user.AddDomainEvent(new UserRoleAssignedEvent(...)) - → _userRepository.UpdateAsync(user) - → _context.SaveChangesAsync() - → DispatchDomainEventsAsync() - → _mediator.Publish(UserRoleAssignedEvent) - → UserRoleAssignedAuditHandler.Handle() - → UserRoleAssignedCacheHandler.Handle() - → UserRoleAssignedNotificationHandler.Handle() - → base.SaveChangesAsync() // Commit transaction -``` - ---- - -## 10.

首次启动 + +```powershell +# Windows +.\scripts\dev-start.ps1 + +# Linux/Mac +chmod +x scripts/dev-start.sh +./scripts/dev-start.sh +``` + +**首次启动流程**: +1. 检查 Docker 是否运行 +2. 创建 `.env` 文件（如果不存在） +3. 拉取并构建所有镜像（约 5-10 分钟） +4. 启动所有容器 +5. 等待健康检查通过 +6. 运行 EF Core 迁移 +7. 自动插入种子数据 +8. 显示访问信息 + +### 4.2 日常开发 + +```powershell +# 前端开发者典型工作流 + +# 1. 启动后端服务 +npm run docker:dev + +# 2. 前端本地开发（热重载） +cd colaflow-web +npm run dev + +# 3. 查看后端日志 +npm run docker:logs + +# 4. 重启后端（修改配置后） +npm run docker:restart + +# 5. 停止所有服务 +npm run docker:stop +``` + +### 4.3 常见场景 + +#### 场景 1：后端代码变更 +```powershell +# 后端代码变更需要重新构建 +docker-compose up -d --build backend +``` + +#### 场景 2：数据库迁移变更 +```powershell +# 应用新迁移 +docker-compose exec backend dotnet ef database update + +# 回滚迁移 +docker-compose exec backend dotnet ef database update +``` + +#### 场景 3：重置开发数据 +```powershell +# Windows +.\scripts\dev-start.ps1 -Reset + +# Linux/Mac +./scripts/dev-start.sh --reset +``` + +#### 场景 4：启用开发工具 +```powershell +# Windows +.\scripts\dev-start.ps1 -Tools + +# Linux/Mac +./scripts/dev-start.sh --tools +``` + +#### 场景 5：调试后端 API +```powershell +# 查看实时日志 +docker-compose logs -f backend + +# 进入容器 +docker-compose exec backend bash + +# 查看数据库连接 +docker-compose exec backend dotnet ef dbcontext info +``` + +### 4.4 前端环境变量配置 + +创建 `colaflow-web/.env.local`: + +```env +# 连接到本地 Docker 容器的后端 +NEXT_PUBLIC_API_URL=http://localhost:5000 +NEXT_PUBLIC_WS_URL=ws://localhost:5000/hubs/project + +# 开发模式设置 +NEXT_PUBLIC_ENABLE_DEBUG=true +NEXT_PUBLIC_ENABLE_ANALYTICS=false + +# 可选：连接到远程后端 +# NEXT_PUBLIC_API_URL=https://dev-api.colaflow.com +``` + +--- + +## 五、性能优化 + +### 5.1 构建缓存优化 + +| 优化项 | 方法 | 效果 | +|--------|------|------| +| **Docker 层缓存** | 先复制 package.json/csproj | 依赖未变时跳过安装 | +| **多阶段构建** | 分离 build 和 runtime | 减少最终镜像大小 50% | +| **npm ci** | 使用 clean install | 比 npm install 快 2-3x | +| **BuildKit** | 启用 Docker BuildKit | 并行构建，提升 30% | + +### 5.2 启用 BuildKit + +在 `.env` 中添加： + +```env +DOCKER_BUILDKIT=1 +COMPOSE_DOCKER_CLI_BUILD=1 +``` + +### 5.3 资源限制 + +在 `docker-compose.yml` 中添加资源限制： + +```yaml +services: + backend: + deploy: + resources: + limits: + cpus: '1.0' + memory: 1G + reservations: + cpus: '0.5' + memory: 512M + + frontend: + deploy: + resources: + limits: + cpus: '1.0' + memory: 1G +``` + +### 5.4 容器启动时间优化 + +| 服务 | 目标启动时间 | 优化方法 | +|------|--------------|----------| +| PostgreSQL | < 5s | 使用 alpine 镜像 | +| Redis | < 3s | 使用 alpine 镜像 | +| Backend | < 30s | 多阶段构建 + 健康检查 | +| Frontend | < 15s | npm ci + 缓存 node_modules | + +--- + +## 六、故障排查 + +### 6.1 常见问题 + +#### 问题 1：容器无法启动 + +**症状**: +``` +Error: Cannot start service backend: ... +``` + +**解决**: +```powershell +# 查看详细日志 +docker-compose logs backend + +# 检查端口占用 +netstat -ano | findstr :5000 + +# 强制重建 +docker-compose up -d --build --force-recreate +``` + +#### 问题 2：数据库连接失败 + +**症状**: +``` +Npgsql.NpgsqlException: Connection refused +``` + +**解决**: +```powershell +# 检查 PostgreSQL 健康状态 +docker-compose ps postgres + +# 查看 PostgreSQL 日志 +docker-compose logs postgres + +# 重启 PostgreSQL +docker-compose restart postgres +``` + +#### 问题 3：前端无法连接后端 + +**症状**: +``` +Failed to fetch: http://localhost:5000/api/... +``` + +**解决**: +1. 检查 `.env.local` 中的 `NEXT_PUBLIC_API_URL` +2. 确认后端健康检查通过：`docker-compose ps backend` +3. 检查 CORS 配置：`docker-compose logs backend | grep CORS` + +#### 问题 4：热重载不工作 + +**症状**: 修改前端代码后浏览器不自动刷新 + +**解决**: +```powershell +# 确认 volume 挂载正确 +docker-compose config | grep -A 5 "frontend.*volumes" + +# 重启前端容器 +docker-compose restart frontend +``` + +### 6.2 诊断命令 + +```powershell +# 检查所有服务状态 +docker-compose ps + +# 查看资源使用 +docker stats + +# 检查网络连接 +docker-compose exec backend curl http://postgres:5432 + +# 查看环境变量 +docker-compose exec backend env | grep CONNECTION + +# 进入容器调试 +docker-compose exec backend bash +docker-compose exec postgres psql -U colaflow +``` + +--- + +## 七、安全考虑 + +### 7.1 开发环境安全清单 + +| 检查项 | 状态 | 说明 | +|--------|------|------| +| ✅ 使用 `.env` 文件 | 推荐 | 不提交到 Git | +| ✅ 强密码策略 | 推荐 | 生产环境必须更改 | +| ⚠️ 暴露端口 | 注意 | 仅开发环境，生产环境需修改 | +| ⚠️ CORS 宽松配置 | 注意 | 仅开发环境，生产环境需限制 | +| ❌ 使用 root 用户 | 禁止 | 前端已使用非 root 用户 | + +### 7.2 .gitignore 配置 + +确保以下文件不被提交： + +```gitignore +# Environment variables +.env +.env.local + +# Docker volumes (if using bind mounts) +.data/ +postgres_data/ +redis_data/ + +# Development certificates +*.pfx +*.pem +``` + +--- + +## 八、CI/CD 集成 + +### 8.1 GitHub Actions 示例 + +```yaml +name: Docker Build Test + +on: + pull_request: + branches: [ main, develop ] + +jobs: + docker-build: +

+**Decision ID**: ADR-036 +**Date**: 2025-11-04 (Day 14 Evening / Day 15 Morning) +**Status**: ACCEPTED +**Decision Makers**: Backend Team + Product Manager + Main Coordinator +**Impact**: HIGH - Core architecture change for M1 milestone + +--- + +## Context + +During Day 13-14 of ColaFlow development, we discovered that the project contains **two different task management implementations**: + +1. **Issue Management Module** - Implemented on Day 13, fully tested, integrated with frontend Kanban board +2. **ProjectManagement Module** - Pre-existing implementation, more complete but未测试, not integrated with frontend + +This duplication creates confusion about which module should be used as the primary architecture for task management in ColaFlow. + +### Background + +**Issue Management Module (Day 13)**: +- Complete CRUD implementation (59 files, 1,630 lines of code) +- Clean Architecture + CQRS + DDD +- 100% multi-tenant security (8/8 integration tests passing, Day 14 security fix) +- Frontend integration complete (Kanban board with drag-drop) +- SignalR real-time notifications (5 domain events) +- Flat issue tracking structure (Project → Issue) + +**ProjectManagement Module (Pre-existing)**: +- More extensive implementation (111 files, 2x code volume) +- Complete three-tier hierarchy (Project → Epic → Story → Task) +- Better DDD design (strong聚合根设计) +- 工时跟踪 (EstimatedHours, ActualHours) +- Better test coverage (10 test files vs 4) +- **BUT**: Multi-tenant security incomplete (only Project has TenantId) +- **BUT**: Not integrated with frontend (APIs unused) + +### Problem Statement + +**Key Questions**: +1. Should we use Issue Management (simpler, tested, integrated) or ProjectManagement (richer, hierarchical)? +2. How do we handle the existing implementation duplication? +3. What is the migration path? +4. What is the risk and effort? + +--- + +## Decision + +**We have decided to adopt ProjectManagement Module** as the primary task management architecture for ColaFlow. + +**Rationale**: + +### 1. Strategic Alignment + +**Product Vision**: ColaFlow aims to be a "Jira-like" agile project management system +- ProjectManagement's Epic → Story → Task hierarchy aligns with Jira's structure +- Issue Management's flat structure is more Kanban-like, not Scrum-compatible +- Our product.md explicitly states: "Epic / Story / Task / Sprint / Workflow" + +**M1 Goals (from product.md)**: +> "M1 (1–2月): 核心项目模块 - Epic/Story 结构、看板、审计日志" + +ProjectManagement Module is the **natural fit** for M1's stated goals. + +### 2.

Long-Term Scalability + +**Epic → Story → Task hierarchy**: +- Supports complex projects with multiple epics +- Aligns with SAFe/Scrum frameworks +- Enables story points and burndown charts +- Supports sprint planning with story-level estimation +- Allows epic-level roadmap views + +**Flat Issue structure limitations**: +- Cannot represent epic-story relationships +- Difficult to organize large projects +- Limited sprint planning capabilities +- No natural hierarchy for reporting + +### 4. Evaluation Report Validation + +On Day 14, the Backend Team conducted a **comprehensive evaluation** of ProjectManagement Module: +- Document: `docs/evaluations/ProjectManagement-Module-Evaluation-2025-11-04.md` +- Conclusion: 85/100 completeness score +- Recommendation: "Should use ProjectManagement Module, but must complete multi-tenant security first" + +### 5. Risk Mitigation + +**Critical Gaps Identified**: +1. ❌ Epic/Story/WorkTask lack TenantId (security risk) +2. ❌ No Global Query Filters on Epic/Story/WorkTask +3. ❌ Frontend not integrated (APIs unused) +4. ❌ Missing authorization on Epics/Stories/Tasks Controllers + +**But**: These gaps are **fixable** (2-3 days effort), and the fix follows the **exact same pattern** as Day 14's Issue Management security fix. + +--- + +## Consequences + +### Positive Consequences + +1. **Alignment with Product Vision** + - ✅ Jira-like experience for users + - ✅ Full agile workflow support (Epic → Story → Task) + - ✅ Better positioning for M2-M6 features (MCP, AI integration) + +2. **Superior Feature Set** + - ✅ Time tracking (EstimatedHours/ActualHours) + - ✅ Natural hierarchy for complex projects + - ✅ Richer reporting capabilities (burndown, velocity) + - ✅ Scalable to enterprise projects (100+ epics, 1000+ stories) + +3. **Code Quality** + - ✅ More mature implementation (111 vs 51 files) + - ✅ Better test coverage (10 vs 4 test files) + - ✅ Superior DDD design + +4. **Future-Proof** + - ✅ Supports planned M1 features (Sprint Management) + - ✅ Supports planned M2 features (AI-generated epics) + - ✅ Supports planned M3 features (PRD → Epic decomposition) + +### Negative Consequences (Mitigated) + +1. **Multi-Tenant Security Gap** (CRITICAL) + - Risk: Epic/Story/Task accessible across tenants + - Mitigation: Apply Day 14 security fix pattern (2-3 days effort) + - Plan: Phase 1 of implementation roadmap + +2. **Frontend Integration Gap** (HIGH) + - Risk: Frontend currently uses Issue Management APIs + - Mitigation: Create API clients, replace API calls (2-3 days effort) + - Plan: Phase 2 of implementation roadmap + +3. **Data Migration** (MEDIUM) + - Risk: Existing Issue data may need migration + - Mitigation: If demo environment, no migration needed;

It's more efficient to fix ProjectManagement's security gaps (2-3 days) than rebuild ProjectManagement's features in Issue Management (2-3 weeks). + +--- + +### Alternative 2: Coexistence of Both Modules + +**Pros**: +- Issue Management for simple Kanban workflows +- ProjectManagement for complex Scrum projects +- Users choose which module to use per project + +**Cons**: +- Doubles maintenance burden (2x codebase to maintain) +- User confusion (which module to use when?) +- Data inconsistency (Project in both modules) +- Frontend complexity (2 sets of APIs) +- Testing complexity (2x test coverage needed) +- Technical debt accumulation + +**Why Rejected**: Coexistence creates long-term technical debt and user confusion. It's better to choose one primary architecture and commit to it. + +--- + +### Alternative 3: Hybrid Approach (Issue Management with Epic/Story extension) + +**Pros**: +- Keeps existing Issue Management implementation +- Extends Issue with ParentIssueId to create hierarchy +- Minimal frontend changes + +**Cons**: +- Issue becomes overloaded entity (Epic, Story, Task all as "Issue") +- Loses semantic clarity (Epic is not just a "big Issue") +- Difficult to enforce Epic → Story → Task hierarchy rules +- No time tracking at Story level (EstimatedHours) +- Complex UI logic to handle different "Issue types" + +**Why Rejected**: This approach is technically feasible but semantically confusing.
