883ef702ac tech-debt: mypy --strict config + integration tests for audit routes
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

4a91814bfc refactor(backend/api): extract AuditSession service layer (Step 4 worked example)
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.

3320ef94fc refactor: phase 0 guardrails + phase 1 step 2 (models.py split)
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.

## Verification

  backend-compliance/.venv-phase1: uv python install 3.12 + pip -r requirements.txt
  PYTHONPATH=. pytest compliance/tests/ tests/contracts/
  -> 173 passed, 0 failed, 35 warnings, OpenAPI 360/484 unchanged
