The monolithic compliance/db/models.py is decomposed into seven sibling
aggregate modules following the existing repo pattern (dsr_models.py,
vvt_models.py, tom_models.py, etc.):
regulation_models.py (134 LOC) — RegulationDB, RequirementDB
control_models.py (279 LOC) — ControlDB, ControlMappingDB, EvidenceDB, RiskDB
ai_system_models.py (141 LOC) — AISystemDB, AuditExportDB
service_module_models.py (176 LOC) — ServiceModuleDB, ModuleRegulationMappingDB, ModuleRiskDB
audit_session_models.py (177 LOC) — AuditSessionDB, AuditSignOffDB
isms_governance_models.py (323 LOC) — ISMSScope, Context, Policy, Objective, SoA
isms_audit_models.py (468 LOC) — AuditFinding, CAPA, ManagementReview, InternalAudit,
AuditTrail, ReadinessCheck
models.py becomes an 85-line re-export shim — every public symbol is
re-exported in dependency order so existing imports work unchanged:
from compliance.db.models import RegulationDB, ControlDB, AuditFindingDB # still works
New code SHOULD import from the aggregate module directly; the shim is
for backwards compatibility during the migration.
Schema freeze preserved:
- __tablename__ byte-identical
- Column names, types, indexes, constraints byte-identical
- relationship() string references and back_populates unchanged
- cascade directives unchanged
Verified:
- 173/173 pytest compliance/tests/ pass
- tests/contracts/test_openapi_baseline.py passes (360 paths,
484 operations — identical to baseline)
- All new sibling files under the 500-line hard cap
(largest: isms_audit_models.py at 468 LOC)
- No file in compliance/db/ now exceeds the hard cap
This is Phase 1 Step 2 from PHASE1_RUNBOOK.md. Phase 1 Step 3 (split
compliance/api/schemas.py, 1899 LOC) is the next target.
