ColaFlow Day 6 Executive Summary
Date: 2025-11-03 Prepared By: Product Manager Agent Target Audience: Development Team, Stakeholders Status: Ready for Implementation
TL;DR (60-Second Summary)
Recommendation: Implement Role Management API on Day 6
Why: Completes tenant user management loop, enables self-service user onboarding, and provides foundation for project-level roles and MCP integration.
Scope: 4 API endpoints, 15+ integration tests, 6-8 hours development time
Risk: LOW (builds on existing RBAC system from Day 5)
Value: HIGH (critical for multi-tenant SaaS operations)
Decision Summary
Day 6 Priority Ranking
| Rank | Feature | Time | Priority | Recommendation |
|---|---|---|---|---|
| 1st | Role Management API | 6-8h | P0 | ✅ IMPLEMENT DAY 6 |
| 2nd | Email Verification | 8-10h | P1 | Defer to Day 7 |
| 3rd | Password Reset | 6-8h | P1 | Defer to Day 7 |
| 4th | Project-Level Roles | 10-12h | P1 | Defer to Day 8 |
| 5th | User Invitations | 10-12h | P1 | Defer to Day 8-9 |
Why Role Management API Won
✅ Immediate Business Value: Tenant admins can manage users (critical for SaaS) ✅ Technical Readiness: RBAC system already complete (Day 5) ✅ Low Risk: No database migrations, no new architecture ✅ Realistic Scope: 6-8 hours fits Day 6 budget ✅ Foundation: Prepares for project roles (Day 8) and MCP (M2)
Day 6 Deliverables
API Endpoints (4 total)
-
POST /api/tenants/{tenantId}/users/{userId}/role
- Assign or update user role
- Authorization: TenantOwner or TenantAdmin
- Security: Cannot assign TenantOwner unless requester is TenantOwner
-
DELETE /api/tenants/{tenantId}/users/{userId}/role
- Remove user from tenant
- Authorization: TenantOwner or TenantAdmin
- Security: Cannot remove last TenantOwner
-
GET /api/tenants/{tenantId}/users
- List all users with roles
- Pagination, filtering, search
- Authorization: TenantMember or higher
-
GET /api/tenants/{tenantId}/roles
- List available roles
- Shows which roles requester can assign
- Authorization: TenantMember or higher
Security Features
- ✅ Role-based authorization policies
- ✅ Privilege escalation prevention
- ✅ Cross-tenant access protection
- ✅ Audit logging (who, what, when)
- ✅ Business rule enforcement (last owner protection, self-modification prevention)
Test Coverage
- 15+ Integration Tests: Full API endpoint coverage
- Edge Cases: Unauthorized access, privilege escalation, cross-tenant
- Security Tests: Token validation, role verification
- Business Rules: Last owner, self-modification, invalid roles
User Stories (Top 3)
US-1: Assign Role to User
As a TenantOwner, I want to assign a role to a user in my tenant, so that I can control their access level to resources.
US-2: Update User Role
As a TenantOwner, I want to change a user's role, so that I can adjust their permissions as their responsibilities change.
US-3: Remove User from Tenant
As a TenantOwner, I want to remove a user from my tenant, so that I can revoke their access when they leave the organization.
Technical Architecture
Database Schema
Table: identity.user_tenant_roles (Already exists from Day 5 ✅)
No migrations required - just add API layer
Existing Repository Methods:
- GetByUserAndTenantAsync ✅
- GetByTenantAsync ✅
- AddAsync ✅
- UpdateAsync ✅
- DeleteAsync ✅
New Method Needed:
- CountByTenantAndRoleAsync (to check if last TenantOwner)
Authorization Rules
| Requester | Can Assign | Cannot Assign | Special Rules |
|---|---|---|---|
| TenantOwner | All roles | - | Full control |
| TenantAdmin | Member, Guest | Owner, Admin | Limited control |
| Others | None | All | No access |
Global Rules:
- Cannot modify own role
- Cannot remove last TenantOwner
- Cannot access other tenants

Why Not Other Options?
Email Verification (Option 2) - Deferred to Day 7
Reasons:
- ❌ Requires email service setup (adds complexity)
- ❌ 8-10 hours (exceeds Day 6 budget)
- ❌ Not critical for MVP (can launch without)
- ✅ Better combined with Password Reset on Day 7
Password Reset (Option 3) - Deferred to Day 7
Reasons:
- ❌ Needs email service (same as Option 2)
- ✅ Better implemented together with Email Verification
- ✅ Day 7 has full email infrastructure
Project-Level Roles (Option 4) - Deferred to Day 8
Reasons:
- ❌ High complexity (10-12 hours)
- ❌ Requires architectural decisions (role inheritance)
- ❌ Depends on Projects module (not yet multi-tenant)
- ✅ Better after tenant roles are stable
User Invitations (Option 5) - Deferred to Day 8-9
Reasons:
- ❌ Requires email service
- ❌ 10-12 hours (too much for Day 6)
- ❌ Complex workflow (invitation → email → acceptance)
- ✅ Better after email service is ready
Strategic Value
Immediate Value (Day 6)
- Self-Service User Management: Tenant admins manage their own users
- Reduced Support Burden: No need to manually assign roles

- Project-Level Roles (Day 8): Build on tenant role patterns
- MCP Integration (M2): AI agents use same role system
- Audit Compliance: Role changes tracked for compliance
- Scalability: Foundation for 1000+ user organizations
