Cost-effective: ~$15,000/year savings vs separate DBs + - Scalable: Handle 1,000+ tenants on single DB + - Simple: Single codebase, single deployment +- **Trade-offs**: Requires careful implementation to prevent cross-tenant data leaks + +**ADR-003: SSO Library Selection** +- **Decision**: ASP.NET Core Native (M1-M2) → Duende IdentityServer (M3+) +- **Rationale**: + - M1-M2: Fast time-to-market, no extra dependencies + - M3+: Enterprise features (advanced SAML, custom IdP) +- **Trade-offs**: Migration effort in M3, but acceptable for enterprise growth + +**ADR-004: MCP Token Format** +- **Decision**: Opaque Token (mcp__) +- **Rationale**: + - Simple: Easy to generate, validate, and revoke + - Secure: No information leakage (unlike JWT) + - Tenant-scoped: Obvious tenant ownership +- **Trade-offs**: Requires database lookup for validation (acceptable overhead) + +**ADR-005: Frontend State Management** +- **Decision**: Zustand (client state) + TanStack Query (server state) +- **Rationale**: + - Zustand: Lightweight, no boilerplate, great TypeScript support + - TanStack Query: Best-in-class server state caching + - Separation: Clear distinction between client and server state +- **Trade-offs**: Learning curve for TanStack Query, but worth it + +**ADR-006: Token Storage Strategy** +- **Decision**: Access Token (memory) + Refresh Token (httpOnly cookie) +- **Rationale**: + - Memory: Secure against XSS (no localStorage) + - httpOnly Cookie: Secure against XSS, automatic sending + - Refresh Logic: Automatic token renewal via interceptor +- **Trade-offs**: Access token lost on page refresh (acceptable, auto-refresh handles it) + +##### Cumulative Documentation Statistics + +**Total Documents Created**: 17 documents (~285KB) + +| Category | Count | Total Size | +|----------|-------|------------| +| Architecture Docs | 5 | 5,150+ lines | +| UI/UX Design Docs | 4 | 38,000+ words | +| Frontend Tech Docs | 4 | 7,100+ lines | +| Project Reports | 4 | 125+ pages | +| **Total** | **17** | **~285KB** | + +**Code Examples in Documentation**: 95+ complete code snippets +**SQL Scripts Provided**: 21+ migration scripts +**Diagrams and Flowcharts**: 30+ visual aids + +##### Backend Code Statistics + +| Metric | Count | +|--------|-------| +| Backend Projects | 3 | +| Test Projects | 2 | +| Source Code Files | 36 (27 Day 1 + 9 Day 2) | +| Unit Tests | 44 (Tenant + User) | +| Integration Tests | 12 (Repository + Filter) | +| Total Tests | 56 | +| Test Pass Rate | 100% | +| Build Status | 0 errors, 0 warnings | + +**Code Structure**: +``` +src/Modules/Identity/ +├── ColaFlow.Modules.Identity.Domain/ (Day 1 -

We need a reliable, performant, and secure method to identify which tenant a user or API request belongs to. + +**Requirements:** +- Must work across web, mobile, and API clients +- Must be stateless (no session storage required) +- Must be secure (prevent tenant spoofing) +- Must be performant (no database lookup per request) +- Must support both human users and AI agents (MCP tokens) +- Must work with subdomain-based URLs (e.g., `acme.colaflow.com`) + +### Decision Drivers + +1. **Performance:** System must handle 10,000+ requests/second without database lookups +2. **Security:** Tenant ID cannot be tampered with by malicious users +3. **Scalability:** Solution must work for mobile apps, APIs, and web simultaneously +4. **Developer Experience:** Easy to implement and maintain across all layers +5. **User Experience:** Friendly tenant selection (via subdomain) + +### Options Considered + +#### Option 1: JWT Claims (Primary) + Subdomain (Secondary) + +**Approach:** +- Store `tenant_id` and `tenant_slug` in JWT access token claims +- Resolve tenant from subdomain on login/registration +- Inject tenant context from JWT claims into all API requests +- No database lookup required after authentication + +**Pros:** +- Stateless: No session storage or database lookup per request +- Secure: JWT signature prevents tampering +- Cross-platform: Works for web, mobile, API, MCP tokens +- Fast: O(1) lookup from JWT claims +- Tenant context available in middleware layer + +**Cons:** +- JWT cannot be updated until refresh (stale tenant info for up to 60 minutes) +- Requires careful token expiration management +- Subdomain only used for initial tenant resolution (login page) + +**Example JWT Payload:** +```json +{ + "sub": "user-id-123", + "email": "john@acme.com", + "tenant_id": "tenant-uuid-456", + "tenant_slug": "acme", + "tenant_plan": "Enterprise", + "auth_provider": "AzureAD", + "role": "User", + "exp": 1730678400, + "iat": 1730674800 +} +``` + +#### Option 2: Session-Based Tenant Storage + +**Approach:** +- Store tenant ID in server-side session (Redis) +- Lookup tenant on every request via session ID +- Subdomain used for tenant resolution on login + +**Pros:** +- Can update tenant info without re-login +- Works well for web applications +- Session can store additional context + +**Cons:** +- Not stateless: Requires Redis/session storage infrastructure +- Database/Redis lookup on every request (performance hit) +- Difficult to scale horizontally (session affinity required) +- Doesn't work well for mobile apps or API-only clients +- MCP tokens would still need separate mechanism + +#### Option 3: Subdomain-Only Identification + +**Approach:** +- Parse subdomain from HTTP Host header on every request +- Lookup tenant by slug in database +- No JWT claims for tenant + +**Pros:** +- Simple conceptual model +- User-friendly (URL shows tenant) +- Easy to test locally + +**Cons:** +- Database lookup on every request (performance bottleneck) +- Doesn't work for API clients (no subdomain in API calls) +- Doesn't work for mobile apps +- Vulnerable to DNS spoofing +- MCP tokens cannot carry subdomain context + +#### Option 4: Tenant ID in URL Path + +**Approach:** +- Include tenant ID in every API route: `/api/tenants/{tenantId}/projects` +- Frontend passes tenant ID explicitly + +**Pros:** +- Explicit tenant context in every request +- Easy to debug +- Works across all client types + +**Cons:** +- Poor user experience (ugly URLs) +- Easy to make mistakes (wrong tenant ID) +- Difficult to enforce (requires middleware validation) +- Security risk (users could try other tenant IDs) +- Requires frontend to manage tenant ID everywhere + +### Decision + +**Chosen Option: Option 1 - JWT Claims (Primary) + Subdomain (Secondary)** + +**Rationale:** +1. **Performance:** No database lookup per request; O(1) from JWT claims +2. **Security:** JWT signature prevents tampering; middleware validates on every request +3. **Scalability:** Works for web, mobile, API, and MCP tokens uniformly +4. **Stateless:** No session storage required; easy to scale horizontally +5. **Developer Experience:** TenantContext injected automatically via middleware + +**Implementation Strategy:** +- **Login Flow:** User visits `acme.colaflow.com/login` → Tenant resolved from subdomain → JWT contains `tenant_id` and `tenant_slug` +- **API Requests:** JWT extracted from Authorization header → `tenant_id` injected into TenantContext → EF Core Global Query Filter applies automatic filtering +- **MCP Tokens:** Opaque tokens stored with `tenant_id` → Middleware validates token → Tenant context injected (same as JWT) + +### Consequences + +**Positive:** +- Fast authentication and authorization +- No session storage infrastructure required +- Uniform tenant resolution across all client types +- Easy to test and debug (tenant visible in JWT payload) +- Supports multi-tenant mobile apps + +**Negative:** +- Tenant changes require re-login (or wait for token refresh) +- JWT size increases slightly (+50 bytes for tenant claims) +- Middleware must validate JWT on every request (minor CPU cost) + +**Neutral:** +- Subdomain is only used for initial tenant selection (login page) +- Tenant switching requires logout and login to different subdomain + +**Mitigation Strategies:** +- Keep JWT expiration short (60 minutes) to allow tenant updates on refresh +- Implement automatic token refresh to minimize user disruption +- Cache JWT validation results per request to avoid redundant checks + +### Validation + +**Acceptance Criteria:** +- JWT contains `tenant_id`, `tenant_slug`, and `tenant_plan` claims +- Middleware extracts tenant from JWT and injects into TenantContext +- All database queries automatically filter by tenant via Global Query Filter +- Cross-tenant access attempts return 403 Forbidden +- Performance: <5ms overhead for JWT validation per request + +**Testing:** +- Unit tests: TenantContext injection +- Integration tests: Cross-tenant isolation +- Performance tests: 10,000 req/s with JWT validation +- Security tests: Attempt to access other tenant's data (should fail) + +### References +- Architecture Doc: `docs/architecture/multi-tenancy-architecture.md` +- JWT Implementation: `docs/architecture/jwt-authentication-architecture.md` +- MCP Token Format: `docs/architecture/mcp-authentication-architecture.md` + +--- + +## ADR-002: Data Isolation Strategy + +### Status +**Accepted** - 2025-11-03 + +### Context + +In a multi-tenant system, data isolation is critical to ensure that one tenant cannot access another tenant's data. We need to choose an isolation strategy that balances security, performance, cost, and maintainability. + +**Requirements:** +- Strong data isolation (no cross-tenant leaks) +- Good query performance (<50ms for typical queries) +- Cost-effective (avoid database proliferation) +- Easy to maintain and backup +- Scalable to 10,000+ tenants +- Support for per-tenant data export (GDPR compliance) + +### Decision Drivers + +1. **Security:** Absolute data isolation between tenants +2. **Cost:** Minimize infrastructure costs (PostgreSQL instances, storage) +3. **Performance:** Fast queries with proper indexing +4. **Scalability:** Support thousands of tenants on shared infrastructure +5. **Maintainability:** Easy schema migrations, backups, monitoring + +### Options Considered + +#### Option 1: Shared Database + tenant_id Column + Global Query Filter + +**Approach:** +- All tenants share one PostgreSQL database +- Every table has a `tenant_id` column (NOT NULL) +- EF Core Global Query Filter automatically adds `.Where(e => e.TenantId == currentTenantId)` to all queries +- Composite indexes: `(tenant_id, other_columns)` + +**Schema Example:** +```sql +CREATE TABLE projects ( + id UUID PRIMARY KEY, + tenant_id UUID NOT NULL REFERENCES tenants(id) ON DELETE CASCADE, + name VARCHAR(200) NOT NULL, + key VARCHAR(20) NOT NULL, + created_at TIMESTAMP NOT NULL DEFAULT NOW(), + CONSTRAINT uq_projects_tenant_key UNIQUE (tenant_id, key) +); + +CREATE INDEX idx_projects_tenant_id ON projects(tenant_id); +CREATE INDEX idx_projects_tenant_key ON projects(tenant_id, key); +``` + +**EF Core Configuration:** +```csharp +protected override void OnModelCreating(ModelBuilder modelBuilder) +{ + modelBuilder.Entity().HasQueryFilter( + p => p.TenantId == _tenantContext.CurrentTenantId + ); +} +``` + +**Pros:** +- Cost-effective: One database for all tenants +- Easy to maintain: Single schema, one backup process +- Good performance with proper indexing (composite indexes) +- Easy to add new tenants (just insert into `tenants` table) +- Per-tenant data export is SQL query: `SELECT * FROM projects WHERE tenant_id = 'xxx'` +- Scales to 10,000+ tenants on one database +- Automatic filtering via Global Query Filter (developer-friendly) + +**Cons:** +- Risk of data leak if Global Query Filter is bypassed (`.IgnoreQueryFilters()`) +- All tenants affected by database downtime +- Cannot isolate noisy neighbors (one tenant's heavy queries affect others) +- Database size grows with all tenants (monitoring required) + +**Cost Estimate:** 1 database instance (~$100-200/month for medium workload) + +#### Option 2: Database-per-Tenant + +**Approach:** +- Each tenant gets a dedicated PostgreSQL database +- Connection string stored in `tenants` table +- Middleware switches database context per request + +**Schema Example:** +```sql +-- Shared management database +CREATE TABLE tenants ( + id UUID PRIMARY KEY, + slug VARCHAR(50) UNIQUE NOT NULL, + connection_string TEXT NOT NULL -- Encrypted +); + +-- Tenant-specific database (one per tenant) +CREATE DATABASE tenant_acme; +CREATE DATABASE tenant_beta; +``` + +**Pros:** +- Strong isolation: One tenant's database cannot access another +- Tenant-specific customization (different schema versions) +- Easy to back up per tenant +- Noisy neighbors don't affect each other +- Easy to migrate tenant to different database server + +**Cons:** +- Expensive: N databases for N tenants (~$10-20/month per tenant minimum) +- Complex maintenance: Schema migrations across 1000s of databases +- Connection pool exhaustion (need one pool per tenant) +- Difficult to implement cross-tenant features (analytics, admin tools) +- Onboarding delay (new database provisioning takes time) + +**Cost Estimate:** 1000 tenants × $15/month = $15,000/month (vs $200 for shared) + +#### Option 3: Schema-per-Tenant (PostgreSQL Schemas) + +**Approach:** +- One database with multiple PostgreSQL schemas +- Each tenant gets a schema: `tenant_acme.projects`, `tenant_beta.projects` +- Middleware switches search_path per request: `SET search_path = tenant_acme;` + +**Pros:** +- Better isolation than shared database +- Lower cost than database-per-tenant +- All tenants in one PostgreSQL instance (easier backups) +- Can support ~1000 schemas per database + +**Cons:** +- PostgreSQL schema limit (~1000 schemas per database) +- Schema creation overhead for new tenants +- Complex schema migrations (run migration on each schema) +- Search_path switching per request (performance overhead) +- Difficult to enforce (easy to forget to set search_path) + +**Cost Estimate:** Same as shared database, but limited scalability + +#### Option 4: Separate Infrastructure per Tenant (Fully Isolated) + +**Approach:** +- Each tenant gets dedicated Kubernetes namespace, database, Redis, etc. +- Complete infrastructure isolation + +**Pros:** +- Maximum isolation and security +- Per-tenant scaling and customization +- Enterprise customers often require this + +**Cons:** +- Extremely expensive (hundreds of dollars per tenant) +- Complex to manage (orchestration required) +- Overkill for most tenants +- Long onboarding time + +**Cost Estimate:** 1000 tenants × $500/month = $500,000/month (prohibitive) + +### Decision + +**Chosen Option: Option 1 - Shared Database + tenant_id Column + Global Query Filter** + +**Rationale:** +1. **Cost-Effective:** $200/month vs $15,000/month for database-per-tenant +2. **Scalable:** PostgreSQL handles 10,000+ tenants with proper indexing +3. **Maintainable:** One schema, one backup process, one monitoring dashboard +4. **Developer-Friendly:** EF Core Global Query Filter ensures automatic filtering +5. **Performance:** Composite indexes provide excellent query performance +6. **Proven Pattern:** Used by GitHub, Slack, Heroku, and many successful SaaS products + +**Implementation Strategy:** +- Add `tenant_id` column to all business tables +- Create composite indexes: `(tenant_id, primary_key)`, `(tenant_id, foreign_key)` +- Configure EF Core Global Query Filter in `OnModelCreating` +- Create TenantContext service to inject current tenant +- Add database-level constraints: `CHECK (tenant_id IS NOT NULL)` +- Update unique constraints to be tenant-scoped: `UNIQUE (tenant_id, email)` + +**Migration Path:** +- Create `tenants` table +- Create default tenant for existing data +- Add `tenant_id` columns (nullable initially) +- Migrate existing data to default tenant +- Set `tenant_id` as NOT NULL +- Add indexes and constraints + +### Consequences + +**Positive:** +- Low infrastructure cost (1 database vs thousands) +- Easy to maintain and monitor +- Fast schema migrations (one database) +- Automatic tenant filtering (developer safety) +- Good query performance with indexes +- Per-tenant data export is straightforward SQL + +**Negative:** +- Risk of data leak if developer bypasses Global Query Filter +- All tenants share database resources (monitoring required) +- Cannot isolate noisy neighbors at database level +- Database backup contains all tenants (larger backup size) + +**Neutral:** +- Tenant onboarding is instant (no new database needed) +- Cross-tenant analytics require explicit filtering +- Database size monitoring required as tenant count grows + +**Mitigation Strategies:** +- **Data Leak Prevention:** + - Code review requirement for any `.IgnoreQueryFilters()` usage + - Integration tests verify cross-tenant isolation + - Automated security testing (attempt cross-tenant access) +- **Performance Monitoring:** + - Alert on slow queries (>100ms) + - Index usage monitoring (pg_stat_user_indexes) + - Per-tenant query cost tracking +- **Noisy Neighbor Protection:** + - Query timeout limits (5 seconds max) + - Rate limiting per tenant + - Connection pool limits + - Option to migrate large tenant to dedicated database later + +**Upgrade Path:** +If a tenant grows too large or requires dedicated resources, we can migrate them to a separate database while keeping the shared model for other tenants. + +### Validation + +**Acceptance Criteria:** +- All queries automatically filter by tenant +- Cross-tenant access attempts fail with 403 Forbidden +- Query performance <50ms for typical workloads (with 10,000 records per tenant) +- Integration tests verify tenant isolation +- Data export per tenant completes in <1 minute + +**Testing:** +- Unit tests: Global Query Filter applied to all entities +- Integration tests: Create data in Tenant A, verify Tenant B cannot access +- Performance tests: Query time with 1 million total records (100 tenants × 10,000 records) +- Load tests: 10,000 concurrent requests across 100 tenants + +### References +- Architecture Doc:

+**Build Status:** +- Compilation: Success +- Warnings: 0 +- Errors: 0 + +--- + +## Key Architecture Decisions (ADR Summary) + +### Decision 1: Tenant Identification Strategy +**Decision:** JWT Claims (Primary) + Subdomain (Secondary) +**Rationale:** +- JWT claims enable stateless authentication +- No database lookup on every request +- Subdomain provides user-friendly tenant selection +- Supports cross-platform authentication (mobile, API, MCP) + +**Alternatives Considered:** +- Database session-based (rejected: not stateless) +- Subdomain only (rejected: doesn't work for API tokens) +- Tenant ID in URL path (rejected: poor UX) + +### Decision 2: Data Isolation Strategy +**Decision:** Shared Database + tenant_id Column + EF Core Global Query Filter +**Rationale:** +- Cost-effective (no database proliferation) +- Easy to maintain and backup +- Good performance with proper indexing +- Scales to thousands of tenants + +**Alternatives Considered:** +- Database-per-tenant (rejected: maintenance complexity, cost) +- Schema-per-tenant (rejected: limited scalability) +- Separate infrastructure per tenant (rejected: over-engineered for current scale) + +### Decision 3: SSO Library Selection +**Decision:** ASP.NET Core Native OIDC/SAML (M1-M2), Consider IdentityServer (M3+) +**Rationale:** +- Built-in to .NET 9, no licensing costs +- Covers 80% of enterprise SSO needs +- Fast implementation (OIDC: 2-3 days, SAML: 3-4 days) +- Can migrate to IdentityServer if complex requirements emerge + +**Alternatives Considered:** +- Auth0 (rejected: expensive, vendor lock-in) +- Okta (rejected: expensive, overkill for MVP) +- IdentityServer4/Duende (deferred: complex, consider for M3+ if needed) + +### Decision 4: MCP Token Format +**Decision:** Opaque Tokens (`mcp__`) +**Rationale:** +- Revocable (database lookup allows instant revocation) +- Fine-grained permissions stored server-side +- Secure (SHA256 hashed, never stored plain-text) +- Tenant-scoped (slug prefix for easy identification) + +**Alternatives Considered:** +- JWT tokens for MCP (rejected: cannot revoke without blacklist) +- API keys without prefix (rejected: no tenant identification) +- Random UUIDs (rejected: less user-friendly, no tenant context) + +### Decision 5: Frontend State Management +**Decision:** Zustand (Client State) + TanStack Query v5 (Server State) +**Rationale:** +- Zustand: Lightweight, TypeScript-first, no boilerplate +- TanStack Query: Built-in caching, automatic refetching, mutations +- Clear separation: Auth in Zustand, API data in TanStack Query +- Performance: Minimal re-renders + +**Alternatives Considered:** +- Redux Toolkit (rejected: too much boilerplate) +- React Context only (rejected: no caching, performance issues) +- Jotai/Recoil (rejected: less mature ecosystem) + +### Decision 6: Token Storage Strategy +**Decision:** Access Token in Memory (Zustand), Refresh Token in httpOnly Cookie +**Rationale:** +- Access token in memory: XSS protection (not in localStorage) +- Refresh token in httpOnly cookie: XSS + CSRF protection +- Short-lived access token (60 min): Limited exposure window +- Automatic refresh: Seamless UX + +**Alternatives Considered:** +- Both in localStorage (rejected: XSS vulnerability) +- Both in cookies (rejected: CSRF vulnerability without careful mitigation) +- Session-based auth (rejected: not stateless, poor mobile support) + +--- + +## Project Metrics + +### Documentation Metrics (Today's Output) + +| Category | Count | Lines/Words | Storage Size |
