Phase 1 Step 4 follow-up addressing the debt flagged in the worked-example
commit (4a91814).
## mypy --strict policy
Adds backend-compliance/mypy.ini declaring the strict-mode scope:
Fully strict (enforced today):
- compliance/domain/
- compliance/schemas/
- compliance/api/_http_errors.py
- compliance/api/audit_routes.py (refactored in Step 4)
- compliance/services/audit_session_service.py
- compliance/services/audit_signoff_service.py
Loose (ignore_errors=True) with a migration path:
- compliance/db/* — SQLAlchemy 1.x Column[] vs
runtime T; unblocks Phase 1
until a Mapped[T] migration.
- compliance/api/<route>.py — each route file flips to
strict as its own Step 4
refactor lands.
- compliance/services/<legacy util> — 14 utility services
(llm_provider, pdf_extractor,
seeder, ...) that predate the
clean-arch refactor.
- compliance/tests/ — excluded (legacy placeholder
style). The new TestClient-
based integration suite is
type-annotated.
The two new service files carry a scoped `# mypy: disable-error-code="arg-type,assignment"`
header for the ORM Column[T] issue — same underlying SQLAlchemy limitation,
narrowly scoped rather than wholesale ignore_errors.
Flow: `cd backend-compliance && mypy compliance/` -> clean on 119 files.
CI yaml updated to use the config instead of ad-hoc package lists.
## Bugs fixed while enabling strict
mypy --strict surfaced two latent bugs in the pre-refactor code. Both
were invisible because the old `compliance/tests/test_audit_routes.py`
is a placeholder suite that asserts on request-data shape and never
calls the handlers:
- AuditSessionResponse.updated_at is a required field in the schema,
but the original handler didn't pass it. Fixed in
AuditSessionService._to_response.
- PaginationMeta requires has_next + has_prev. The original audit
checklist handler didn't compute them. Fixed in
AuditSignOffService.get_checklist.
Both are behavior-preserving at the HTTP level because the old code
would have raised Pydantic ValidationError at response serialization
had the endpoint actually been exercised.
## Integration test suite
Adds backend-compliance/tests/test_audit_routes_integration.py — 26
real TestClient tests against an in-memory sqlite backend (StaticPool).
Replaces the coverage gap left by the placeholder suite.
Covers:
- Session CRUD + lifecycle transitions (draft -> in_progress -> completed
-> archived), including the 409 paths for illegal transitions
- Checklist pagination, filtering, search
- Sign-off create / update / auto-start-session / count-flipping
- Sign-off 400 (invalid result), 404 (missing requirement), 409 (completed session)
- Get-signoff 404 / 200 round-trip
Uses a module-scoped schema fixture + per-test DELETE-sweep so the
suite runs in ~2.3s despite the ~50-table ORM surface.
Verified:
- 199/199 pytest (173 original + 26 new audit integration) pass
- tests/contracts/test_openapi_baseline.py green, OpenAPI 360/484 unchanged
- mypy compliance/ -> Success: no issues found in 119 source files

Phase 1 Step 4 of PHASE1_RUNBOOK.md, first worked example. Demonstrates
the router -> service delegation pattern for all 18 oversized route
files still above the 500 LOC hard cap.
compliance/api/audit_routes.py (637 LOC) is decomposed into:
compliance/api/audit_routes.py (198) — thin handlers
compliance/services/audit_session_service.py (259) — session lifecycle
compliance/services/audit_signoff_service.py (319) — checklist + sign-off
compliance/api/_http_errors.py ( 43) — reusable error translator
Handlers shrink to 3-6 lines each:
@router.post("/sessions", response_model=AuditSessionResponse)
async def create_audit_session(
request: CreateAuditSessionRequest,
service: AuditSessionService = Depends(get_audit_session_service),
):
with translate_domain_errors():
return service.create(request)
Services are HTTP-agnostic: they raise NotFoundError / ConflictError /
ValidationError from compliance.domain, and the route layer translates
those to HTTPException(404/409/400) via the translate_domain_errors()
context manager in compliance.api._http_errors. The error translator is
reusable by every future Step 4 refactor.
Services take a sqlalchemy Session in the constructor and are wired via
Depends factories (get_audit_session_service / get_audit_signoff_service).
No globals, no module-level state.
Behavior is byte-identical at the HTTP boundary:
- Same paths, methods, status codes, response models
- Same error messages (domain error __str__ preserved)
- Same auto-start-on-first-signoff, same statistics calculation,
same signature hash format, same PDF streaming response
Verified:
- 173/173 pytest compliance/tests/ tests/contracts/ pass
- OpenAPI 360 paths / 484 operations unchanged
- audit_routes.py under soft 300 target
- Both new service files under soft 300 / hard 500
Note: compliance/tests/test_audit_routes.py contains placeholder tests
that do not actually import or call the handler functions — they only
assert on request-data shape. Real behavioral coverage relies on the
contract test. A follow-up commit should add TestClient-based
integration tests for the audit endpoints. Flagged in PHASE1_RUNBOOK.

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
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Phase 1 Step 3 of PHASE1_RUNBOOK.md. compliance/api/schemas.py is
decomposed into 16 per-domain Pydantic schema modules under
compliance/schemas/:
common.py ( 79) — 6 API enums + PaginationMeta
regulation.py ( 52)
requirement.py ( 80)
control.py (119) — Control + Mapping
evidence.py ( 66)
risk.py ( 79)
ai_system.py ( 63)
dashboard.py (195) — Dashboard, Export, Executive Dashboard
service_module.py (121)
bsi.py ( 58) — BSI + PDF extraction
audit_session.py (172)
report.py ( 53)
isms_governance.py (343) — Scope, Context, Policy, Objective, SoA
isms_audit.py (431) — Finding, CAPA, Review, Internal Audit, Readiness, Trail, ISO27001
vvt.py (168)
tom.py ( 71)
compliance/api/schemas.py becomes a 39-line re-export shim so existing
imports (from compliance.api.schemas import RegulationResponse) keep
working unchanged. New code should import from the domain module
directly (from compliance.schemas.regulation import RegulationResponse).
Deferred-from-sweep: all 28 class Config blocks in the original file
were converted to model_config = ConfigDict(...) during the split.
schemas.py-sourced PydanticDeprecatedSince20 warnings are now gone.
Cross-domain references handled via targeted imports (e.g. dashboard.py
imports EvidenceResponse from evidence, RiskResponse from risk). common
API enums + PaginationMeta are imported by every domain module.
Verified:
- 173/173 pytest compliance/tests/ tests/contracts/ pass
- OpenAPI 360 paths / 484 operations unchanged (contract test green)
- All new files under the 500-line hard cap (largest: isms_audit.py

- No file in compliance/schemas/ or compliance/api/schemas.py
exceeds the hard cap

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.
