compliance/api/evidence_routes.py (641 LOC) -> 240 LOC thin routes + 460-line
EvidenceService. Manages evidence CRUD, file upload, CI/CD evidence
collection (SAST/dependency/SBOM/container scans), and CI status dashboard.
Service injection pattern: EvidenceService takes the EvidenceRepository,
ControlRepository, and AutoRiskUpdater classes as constructor parameters.
The route's get_evidence_service factory reads these class references from
its own module namespace so tests that
``patch("compliance.api.evidence_routes.EvidenceRepository", ...)`` still
take effect through the factory.
The `_store_evidence` and `_update_risks` helpers stay as module-level
callables in evidence_service and are re-exported from the route module.
The collect_ci_evidence handler remains inline (not delegated to a service
method) so tests can patch
`compliance.api.evidence_routes._store_evidence` and have the patch take
effect at the handler's call site.
Legacy re-exports via __all__: SOURCE_CONTROL_MAP, EvidenceRepository,
ControlRepository, AutoRiskUpdater, _parse_ci_evidence,
_extract_findings_detail, _store_evidence, _update_risks.
Verified:
- 208/208 pytest (core + 35 evidence tests) pass
- OpenAPI 360/484 unchanged
- mypy compliance/ -> Success on 135 source files
- evidence_routes.py 641 -> 240 LOC
- Hard-cap violations: 10 -> 9
