compliance/api/tom_routes.py (609 LOC) -> 215 LOC thin routes + 434-line TOMService. Request bodies (TOMStateBody, TOMMeasureCreate, TOMMeasureUpdate, TOMMeasureBulkItem, TOMMeasureBulkBody) moved to compliance/schemas/tom.py (joining the existing response models from the Step 3 split). Single-service split (not two like banner): state, measures CRUD + bulk upsert, stats, export, and version lookups are all tightly coupled around the TOMMeasureDB aggregate, so splitting would create artificial boundaries. TOMService is 434 LOC — comfortably under the 500 hard cap. Domain error mapping: - ConflictError -> 409 (version conflict on state save; duplicate control_id on create) - NotFoundError -> 404 (missing measure on update; missing version) - ValidationError -> 400 (missing tenant_id on DELETE /state) Legacy test compat: the existing tests/test_tom_routes.py imports TOMMeasureBulkItem, _parse_dt, _measure_to_dict, and DEFAULT_TENANT_ID directly from compliance.api.tom_routes. All re-exported via __all__ so the 44-test file runs unchanged. mypy.ini flips compliance.api.tom_routes from ignore_errors=True to False. TOMService carries the scoped Column[T] header. Verified: - 217/217 pytest (173 baseline + 44 TOM) pass - OpenAPI 360/484 unchanged - mypy compliance/ -> Success on 124 source files - tom_routes.py 609 -> 215 LOC - Hard-cap violations: 16 -> 15 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
