=== IMPLEMENTATION COMPLETED ===

✅ AppDbContext created with DbSets for all 5 entities
✅ Entity configurations via IEntityTypeConfiguration<T> pattern
✅ PostgreSQL xmin concurrency tokens on WorkItem and Shift
✅ TenantDbConnectionInterceptor with SET LOCAL for RLS
✅ SaveChangesTenantInterceptor for auto-assigning TenantId
✅ EF Core migration generated: 20260303132952_InitialCreate
✅ RLS policies SQL script created: add-rls-policies.sql
✅ Interceptors registered in Program.cs DI container
✅ Finbuckle.MultiTenant v10 API compatibility verified

=== CHANGES MADE ===

Modified Files:
- backend/WorkClub.Api/Program.cs
  * Added singleton registrations for both interceptors
  * Updated DbContext registration to use service provider and .AddInterceptors()
  
- backend/WorkClub.Infrastructure/Services/TenantProvider.cs  
  * Updated to Finbuckle v10 API (IMultiTenantContextAccessor without generic)

- backend/WorkClub.Domain/Entities/WorkItem.cs
  * Changed RowVersion type from byte[]? to uint for xmin

- backend/WorkClub.Domain/Entities/Shift.cs
  * Changed RowVersion type from byte[]? to uint for xmin

Created Files:
- backend/WorkClub.Infrastructure/Data/AppDbContext.cs
- backend/WorkClub.Infrastructure/Data/Configurations/*.cs (5 configuration classes)
- backend/WorkClub.Infrastructure/Data/Interceptors/*.cs (2 interceptor classes)
- backend/WorkClub.Infrastructure/Migrations/20260303132952_InitialCreate.*
- backend/WorkClub.Infrastructure/Migrations/add-rls-policies.sql
- backend/WorkClub.Tests.Integration/Data/MigrationTests.cs
- backend/WorkClub.Tests.Integration/Data/RlsTests.cs

=== PENDING TASKS ===

⏳ Database setup blocked by Docker/Colima issues:
- Colima VM failed to start (disk attachment error)
- Docker Desktop not installed
- PostgreSQL not available locally

Manual steps required (when Docker is available):
1. Start PostgreSQL: docker compose up -d postgres
2. Apply migration: cd backend && dotnet ef database update --project WorkClub.Infrastructure --startup-project WorkClub.Api
3. Apply RLS: psql -h localhost -U app_admin -d workclub -f backend/WorkClub.Infrastructure/Migrations/add-rls-policies.sql
4. Run tests: dotnet test backend/WorkClub.Tests.Integration --filter "FullyQualifiedName~MigrationTests|RlsTests"

=== VERIFICATION STATUS ===

✅ Code compiles without errors
✅ All dependencies resolved
✅ Interceptor pattern correctly implemented with SET LOCAL (transaction-scoped)
✅ Finbuckle v10 compatibility verified
⏳ Integration tests pending (require PostgreSQL)
⏳ Migration application pending (require PostgreSQL)
⏳ RLS policies pending (require PostgreSQL)

=== SECURITY NOTES ===

✅ CRITICAL REQUIREMENT MET: Using SET LOCAL (transaction-scoped) not SET (session-scoped)
  - Prevents cross-tenant data leaks with connection pooling
  - Implementation in TenantDbConnectionInterceptor line 33

✅ RLS policies use current_setting('app.current_tenant_id', true)::text
  - Second parameter returns NULL instead of error when unset
  - Prevents crashes when tenant context not available

✅ ShiftSignups RLS uses subquery pattern (no direct TenantId)
  - Policy: "ShiftId" IN (SELECT "Id" FROM shifts WHERE "TenantId" = ...)

=== NEXT SESSION REQUIREMENTS ===

To complete Task 7, next session must:
1. Fix Docker/Colima environment or install PostgreSQL locally
2. Apply migration and RLS policies
3. Run integration tests (MigrationTests + RlsTests)
4. Verify tests pass (TDD green phase)
5. Save test evidence
6. Update learnings.md with Finbuckle v10 migration notes

DO NOT COMMIT - Task 7 and Task 8 will be committed together per directive.
