Phase 1 Step 5 of PHASE1_RUNBOOK.md.
compliance/db/repository.py (1547 LOC) decomposed into seven sibling
per-aggregate repository modules:
regulation_repository.py (268) — Regulation + Requirement
control_repository.py (291) — Control + ControlMapping
evidence_repository.py (143)
risk_repository.py (148)
audit_export_repository.py (110)
service_module_repository.py (247)
audit_session_repository.py (478) — AuditSession + AuditSignOff
compliance/db/isms_repository.py (838 LOC) decomposed into two
sub-aggregate modules mirroring the models split:
isms_governance_repository.py (354) — Scope, Policy, Objective, SoA
isms_audit_repository.py (499) — Finding, CAPA, Review, Internal Audit,
Trail, Readiness
Both original files become thin re-export shims (37 and 25 LOC
respectively) so every existing import continues to work unchanged.
New code SHOULD import from the aggregate module directly.
All new sibling files under the 500-line hard cap; largest is
isms_audit_repository.py at 499 (on the edge; when Phase 1 Step 4
router->service extraction lands, the audit_session repo may split
further if growth exceeds 500).
Verified:
- 173/173 pytest compliance/tests/ tests/contracts/ pass
- OpenAPI 360 paths / 484 operations unchanged
- All repo files under 500 LOC

Squash of branch refactor/phase0-guardrails-and-models-split — 4 commits,
81 files, 173/173 pytest green, OpenAPI contract preserved (360 paths /
484 operations).
## Phase 0 — Architecture guardrails
Three defense-in-depth layers to keep the architecture rules enforced
regardless of who opens Claude Code in this repo:
1. .claude/settings.json PreToolUse hook on Write/Edit blocks any file
that would exceed the 500-line hard cap. Auto-loads in every Claude
session in this repo.
2. scripts/githooks/pre-commit (install via scripts/install-hooks.sh)
enforces the LOC cap locally, freezes migrations/ without
[migration-approved], and protects guardrail files without
[guardrail-change].
3. .gitea/workflows/ci.yaml gains loc-budget + guardrail-integrity +
sbom-scan (syft+grype) jobs, adds mypy --strict for the new Python
packages (compliance/{services,repositories,domain,schemas}), and
tsc --noEmit for admin-compliance + developer-portal.
Per-language conventions documented in AGENTS.python.md, AGENTS.go.md,
AGENTS.typescript.md at the repo root — layering, tooling, and explicit
"what you may NOT do" lists. Root CLAUDE.md is prepended with the six
non-negotiable rules. Each of the 10 services gets a README.md.
scripts/check-loc.sh enforces soft 300 / hard 500 and surfaces the
current baseline of 205 hard + 161 soft violations so Phases 1-4 can
drain it incrementally. CI gates only CHANGED files in PRs so the
legacy baseline does not block unrelated work.
## Deprecation sweep
47 files. Pydantic V1 regex= -> pattern= (2 sites), class Config ->
ConfigDict in source_policy_router.py (schemas.py intentionally skipped;
it is the Phase 1 Step 3 split target). datetime.utcnow() ->
datetime.now(timezone.utc) everywhere including SQLAlchemy default=
callables. All DB columns already declare timezone=True, so this is a
latent-bug fix at the Python side, not a schema change.
DeprecationWarning count dropped from 158 to 35.
## Phase 1 Step 1 — Contract test harness
tests/contracts/test_openapi_baseline.py diffs the live FastAPI /openapi.json
against tests/contracts/openapi.baseline.json on every test run. Fails on
removed paths, removed status codes, or new required request body fields.
Regenerate only via tests/contracts/regenerate_baseline.py after a
consumer-updated contract change. This is the safety harness for all
subsequent refactor commits.
## Phase 1 Step 2 — models.py split (1466 -> 85 LOC shim)
compliance/db/models.py is decomposed into seven sibling aggregate modules
following the existing repo pattern (dsr_models.py, vvt_models.py, ...):
regulation_models.py (134) — Regulation, Requirement
control_models.py (279) — Control, Mapping, Evidence, Risk
ai_system_models.py (141) — AISystem, AuditExport
service_module_models.py (176) — ServiceModule, ModuleRegulation, ModuleRisk
audit_session_models.py (177) — AuditSession, AuditSignOff
isms_governance_models.py (323) — ISMSScope, Context, Policy, Objective, SoA
isms_audit_models.py (468) — Finding, CAPA, MgmtReview, InternalAudit,
AuditTrail, Readiness
models.py becomes an 85-line re-export shim in dependency order so
existing imports continue to work unchanged. Schema is byte-identical:
__tablename__, column definitions, relationship strings, back_populates,
cascade directives all preserved.
All new sibling files are under the 500-line hard cap; largest is
isms_audit_models.py at 468. No file in compliance/db/ now exceeds
the hard cap.
## Phase 1 Step 3 — infrastructure only
backend-compliance/compliance/{schemas,domain,repositories}/ packages
are created as landing zones with docstrings. compliance/domain/
exports DomainError / NotFoundError / ConflictError / ValidationError /
PermissionError — the base classes services will use to raise
domain-level errors instead of HTTPException.
PHASE1_RUNBOOK.md at backend-compliance/PHASE1_RUNBOOK.md documents
the nine-step execution plan for Phase 1: snapshot baseline,
characterization tests, split models.py (this commit), split schemas.py
(next), extract services, extract repositories, mypy --strict, coverage.
