compliance/api/email_template_routes.py (823 LOC) -> 295 LOC thin routes
+ 402-line EmailTemplateService + 241-line EmailTemplateVersionService +
61-line schemas file.
Two-service split along natural responsibility seam:
email_template_service.py (402 LOC):
- Template type catalog (TEMPLATE_TYPES constant)
- Template CRUD (list, create, get)
- Stats, settings, send logs, initialization, default content
- Shared _template_to_dict / _version_to_dict / _render_template helpers
email_template_version_service.py (241 LOC):
- Version CRUD (create, list, get, update)
- Workflow transitions (submit, approve, reject, publish)
- Preview and test-send
TEMPLATE_TYPES, VALID_CATEGORIES, VALID_STATUSES re-exported from the
route module for any legacy consumers.
State-transition errors use ValidationError (-> HTTPException 400) to
preserve the original handler's 400 status for "Only draft/review
versions can be ..." checks, since the existing TestClient integration
tests (47 tests) assert status_code == 400.
Verified:
- 47/47 tests/test_email_template_routes.py pass
- OpenAPI 360/484 unchanged
- mypy compliance/ -> Success on 138 source files
- email_template_routes.py 823 -> 295 LOC
- Hard-cap violations: 9 -> 8
