Fix architectural issue where tenant isolation logic was incorrectly placed in the Application layer (Handlers) instead of the Infrastructure layer (DbContext/Repository). Changes: - Removed ITenantContext injection from 12 Command/Query Handlers - Removed manual tenant verification code from all handlers - Tenant isolation now handled exclusively by Global Query Filters in PMDbContext - Handlers now focus purely on business logic, not cross-cutting concerns Architecture Benefits: - Proper separation of concerns (Handler = business logic, DbContext = tenant filtering) - Eliminates code duplication across handlers - Follows Repository pattern correctly - Single Responsibility Principle compliance - Cleaner, more maintainable code Affected Handlers: - CreateEpicCommandHandler - UpdateEpicCommandHandler - CreateStoryCommandHandler - UpdateStoryCommandHandler - AssignStoryCommandHandler - DeleteStoryCommandHandler - CreateTaskCommandHandler - UpdateTaskCommandHandler - AssignTaskCommandHandler - DeleteTaskCommandHandler - UpdateTaskStatusCommandHandler - GetEpicByIdQueryHandler Technical Notes: - PMDbContext already has Global Query Filters configured correctly - Project aggregate passes TenantId when creating child entities - Repository queries automatically filtered by tenant via EF Core filters 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
