Changelog

All notable changes to this project will be documented in this file.

Breaking Changes

• Converted all primary keys from UUID to auto-incrementing integer across all modules (base model, user, todo, tenants, api_key, authorization). Existing databases must run the new Alembic migration to convert id columns and preserve foreign key constraint names and indexes.
• API responses now serialize entity IDs as integers instead of UUID strings.

Added

• Multitenancy support:
  • TenantMixin base model providing tenant_id column on all models.
  • New tenants module with model, entity, repository, and dependencies.
  • TenantMiddleware resolving tenants via header, subdomain, or JWT claims.
  • Tenant dependency registered in the application and default tenant seeding on startup.
  • MULTITENANT_ENABLED configuration flag.
  • Alembic migration for the multitenant schema.
• Module facade pattern replacing the user provider, exposing module capabilities through dedicated facades.

Changed

• Integer primary keys propagated through domain entities, commands, repositories, and application/presentation layers.
• Cursor pagination now parses integer IDs.
• All repositories filter by tenant_id; repository factories and unit of work receive tenant_id.
• Tenant seed relies on database-assigned integer IDs.

Fixed

• Alembic ID conversion migration preserves foreign key constraint names and indexes.
• Entity IDs serialized as integers in response schemas.
• Tenant model registered in seed runner metadata.
• Flush ordering for related records and token update semantics.
