This commit completes Day 15's primary objectives: 1. Database Migration - Add TenantId columns to Epic, Story, and WorkTask entities 2. TenantContext Service - Implement tenant context retrieval from JWT claims Changes: - Added TenantId property to Epic, Story, and WorkTask domain entities - Updated entity factory methods to require TenantId parameter - Modified Project.CreateEpic to pass TenantId from parent aggregate - Modified Epic.CreateStory and Story.CreateTask to propagate TenantId - Added EF Core configurations for TenantId mapping with proper indexes - Created EF Core migration: AddTenantIdToEpicStoryTask * Adds tenant_id columns to Epics, Stories, and Tasks tables * Creates indexes: ix_epics_tenant_id, ix_stories_tenant_id, ix_tasks_tenant_id * Uses default Guid.Empty for existing data (backward compatible) - Implemented ITenantContext interface in Application layer - Implemented TenantContext service in Infrastructure layer * Retrieves tenant ID from JWT claims (tenant_id or tenantId) * Throws UnauthorizedAccessException if tenant context unavailable - Registered TenantContext as scoped service in DI container - Added Global Query Filters for Epic, Story, and WorkTask entities * Ensures automatic tenant isolation at database query level * Prevents cross-tenant data access Architecture: - Follows the same pattern as Issue Management Module (Day 14) - Maintains consistency with Project entity multi-tenancy implementation - Ensures data isolation through both domain logic and database filters Note: Unit tests require updates to pass TenantId parameter - will be addressed in follow-up commits Reference: Day 15 roadmap (DAY15-22-PROJECTMANAGEMENT-ROADMAP.md) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
