Set up Husky at repository root to run automated checks before commits.
Changes:
- Installed Husky 9.1.7 in project root
- Created .husky/pre-commit hook
- Hook runs TypeScript compilation check (tsc --noEmit)
- Hook runs lint-staged for fast linting on staged files only
- Added package.json and package-lock.json for Husky dependency
Pre-commit workflow:
1. cd colaflow-web
2. Run TypeScript check on all files
3. Run lint-staged (ESLint + Prettier) on staged files only
Note: Using --no-verify for this commit to avoid chicken-egg problem.

Fixed BUG-007 where database migrations failed during initialization because the
user_tenant_roles table was never created by any migration, but a later migration
tried to modify it.
Root Cause:
- The user_tenant_roles table was configured in IdentityDbContext but missing from InitialIdentityModule migration
- Migration 20251103150353_FixUserTenantRolesIgnoreNavigation tried to drop/recreate foreign keys on a non-existent table
- This caused application startup to fail with "relation user_tenant_roles does not exist"
Solution:
- Made the migration idempotent by checking table existence before operations
- If table doesn't exist, create it with proper schema, indexes, and constraints
- Drop foreign keys only if they exist (safe for both first run and re-runs)
- Corrected principal schema references (users/tenants are in default schema at this migration point)
- Removed duplicate ix_user_tenant_roles_tenant_role index (created by later migration)
Testing:
- Clean database initialization: ✅ SUCCESS
- All migrations applied successfully: ✅ SUCCESS
- Application starts and listens: ✅ SUCCESS
- Foreign keys created correctly: ✅ SUCCESS
Impact:
- Fixes P0 CRITICAL bug blocking Docker environment delivery
- Enables clean database initialization from scratch
- Maintains backward compatibility with existing databases

Fixed critical P0 bug where application failed to start due to missing
IApplicationDbContext registration in dependency injection container.
Root Cause:
- Sprint command handlers (CreateSprint, UpdateSprint, etc.) depend on IApplicationDbContext
- PMDbContext implements IApplicationDbContext but interface was not registered in DI
- ASP.NET Core DI validation failed at application startup
Solution:
- Added IApplicationDbContext interface registration in ModuleExtensions.cs
- Maps interface to PMDbContext implementation using service provider
Impact:
- Application can now start successfully
- All Sprint command handlers can resolve their dependencies
- Docker container startup will succeed
Testing:
- Local build: SUCCESS
- Docker build: PENDING QA validation

CRITICAL SECURITY FIX: Implemented Defense in Depth security pattern by adding
explicit TenantId verification to all Epic/Story/Task Query and Command Handlers.
Security Impact:
- BEFORE: Relied solely on EF Core global query filters (single layer)
- AFTER: Explicit TenantId validation + EF Core filters (defense in depth)
This ensures that even if EF Core query filters are accidentally disabled or bypassed,
tenant isolation is still maintained at the application layer.
Changes:
Query Handlers (6 handlers):
- GetEpicByIdQueryHandler: Added ITenantContext injection + explicit TenantId check
- GetStoryByIdQueryHandler: Added ITenantContext injection + explicit TenantId check
- GetTaskByIdQueryHandler: Added ITenantContext injection + explicit TenantId check
- GetEpicsByProjectIdQueryHandler: Verify Project.TenantId before querying Epics
- GetStoriesByEpicIdQueryHandler: Verify Epic.TenantId before querying Stories
- GetTasksByStoryIdQueryHandler: Verify Story.TenantId before querying Tasks
Command Handlers (5 handlers):
- UpdateEpicCommandHandler: Verify Project.TenantId before updating
- UpdateStoryCommandHandler: Verify Project.TenantId before updating
- UpdateTaskCommandHandler: Verify Project.TenantId before updating
- DeleteStoryCommandHandler: Verify Project.TenantId before deleting
- DeleteTaskCommandHandler: Verify Project.TenantId before deleting
Unit Tests:
- Updated 5 unit test files to mock ITenantContext
- All 32 unit tests passing
- All 7 multi-tenant isolation integration tests passing
Defense Layers (Security in Depth):
Layer 1: EF Core global query filters (database level)
Layer 2: Application-layer explicit TenantId validation (handler level)
Layer 3: Integration tests verifying tenant isolation (test level)
Test Results:
- Unit Tests: 32/32 PASSING
- Integration Tests: 7/7 PASSING (multi-tenant isolation)
This fix addresses a critical security vulnerability where we relied on a single
layer of defense (EF Core query filters) for tenant data isolation. Now we have
multiple layers ensuring no cross-tenant data leaks can occur.

CRITICAL SECURITY FIX: Removed client-provided TenantId parameter from
CreateProjectCommand to prevent tenant impersonation attacks.
Changes:
- Removed TenantId property from CreateProjectCommand
- Injected ITenantContext into CreateProjectCommandHandler
- Now retrieves authenticated TenantId from JWT token via TenantContext
- Prevents malicious users from creating projects under other tenants
Security Impact:
- Before: Client could provide any TenantId (HIGH RISK)
- After: TenantId extracted from authenticated JWT token (SECURE)
Note: CreateEpic, CreateStory, and CreateTask commands were already secure
as they inherit TenantId from parent entities loaded via Global Query Filters.
