This commit completes the migration to a fully module-driven architecture:
## Models Migration
- Moved all domain models from models/database/ to their respective modules:
- tenancy: User, Admin, Vendor, Company, Platform, VendorDomain, etc.
- cms: MediaFile, VendorTheme
- messaging: Email, VendorEmailSettings, VendorEmailTemplate
- core: AdminMenuConfig
- models/database/ now only contains Base and TimestampMixin (infrastructure)
## Schemas Migration
- Moved all domain schemas from models/schema/ to their respective modules:
- tenancy: company, vendor, admin, team, vendor_domain
- cms: media, image, vendor_theme
- messaging: email
- models/schema/ now only contains base.py and auth.py (infrastructure)
## Routes Migration
- Moved admin routes from app/api/v1/admin/ to modules:
- menu_config.py -> core module
- modules.py -> tenancy module
- module_config.py -> tenancy module
- app/api/v1/admin/ now only aggregates auto-discovered module routes
## Menu System
- Implemented module-driven menu system with MenuDiscoveryService
- Extended FrontendType enum: PLATFORM, ADMIN, VENDOR, STOREFRONT
- Added MenuItemDefinition and MenuSectionDefinition dataclasses
- Each module now defines its own menu items in definition.py
- MenuService integrates with MenuDiscoveryService for template rendering
## Documentation
- Updated docs/architecture/models-structure.md
- Updated docs/architecture/menu-management.md
- Updated architecture validation rules for new exceptions
## Architecture Validation
- Updated MOD-019 rule to allow base.py in models/schema/
- Created core module exceptions.py and schemas/ directory
- All validation errors resolved (only warnings remain)

MIGRATION:
- Delete app/api/v1/vendor/analytics.py (duplicate - analytics module already auto-discovered)
- Move usage routes from app/api/v1/vendor/usage.py to billing module
- Move onboarding routes from app/api/v1/vendor/onboarding.py to marketplace module
- Move features routes to billing module (admin + vendor)
- Move inventory routes to inventory module (admin + vendor)
- Move marketplace/letzshop routes to marketplace module
- Move orders routes to orders module
- Delete legacy letzshop service files (moved to marketplace module)
DOCUMENTATION:
- Add docs/development/migration/module-autodiscovery-migration.md with full migration history
- Update docs/architecture/module-system.md with Entity Auto-Discovery Reference section
- Add detailed sections for each entity type: routes, services, models, schemas, tasks,
exceptions, templates, static files, locales, configuration
ARCHITECTURE VALIDATION:
- Add MOD-016: Routes must be in modules, not app/api/v1/
- Add MOD-017: Services must be in modules, not app/services/
- Add MOD-018: Tasks must be in modules, not app/tasks/
- Add MOD-019: Schemas must be in modules, not models/schema/
- Update scripts/validate_architecture.py with _validate_legacy_locations method
- Update .architecture-rules/module.yaml with legacy location rules
These rules enforce that all entities must be in self-contained modules.
Legacy locations now trigger ERROR severity violations.

Transform CMS from a thin wrapper into a fully self-contained module with
all code living within app/modules/cms/:
Module Structure:
- models/: ContentPage model (canonical location with dynamic discovery)
- schemas/: Pydantic schemas for API validation
- services/: ContentPageService business logic
- exceptions/: Module-specific exceptions
- routes/api/: REST API endpoints (admin, vendor, shop)
- routes/pages/: HTML page routes (admin, vendor)
- templates/cms/: Jinja2 templates (namespaced)
- static/: JavaScript files (admin/vendor)
- locales/: i18n translations (en, fr, de, lb)
Key Changes:
- Move ContentPage model to module with dynamic model discovery
- Create Pydantic schemas package for request/response validation
- Extract API routes from app/api/v1/*/ to module
- Extract page routes from admin_pages.py/vendor_pages.py to module
- Move static JS files to module with dedicated mount point
- Update templates to use cms_static for module assets
- Add module static file mounting in main.py
- Delete old scattered files (no shims - hard errors on old imports)
This establishes the pattern for migrating other modules to be
fully autonomous and independently deployable.
