Before flipping control-mapping rows, wire the Phase 0 promises that had
no code behind them yet:
- SI-11 / C.5.7.43: app-wide exception handler returns
{"error":"internal_error","request_id":...} and the X-Request-ID header.
Logs exception type + stack frames, not the message — driver errors
echo bound parameters and key values. Engine set to hide_parameters.
- AU-11 / SI-12 (plan §7 risk): create_app refuses to start if any
mapped table lacks a retention policy.
- CM-3: migrations/IMMUTABLE.sha256 pins every merged revision; a test
fails on any edit or on an unpinned new revision.
- migrations/env.py: fileConfig(disable_existing_loggers=False) so
in-process Alembic (the drift test) doesn't silence app loggers.
163 tests passing; ruff, mypy, bandit, gitleaks clean.

Every mapped table resolves a retention policy; a report-only job runs
over all of them and logs "N records to purge". ARCH §6.4; NIST AU-11,
SI-12; source RFP C.5.7.42.
- framework/retention.py: RetentionPolicy (data class, disposal, period,
anchor column, cadence, approved, authority), run_retention(), and a
`python -m ypms.framework.retention` entrypoint. Phase 0 never mutates
data: interim-period rows are counted (interim_eligible), approved-period
rows are counted (to_purge), nothing is purged. One retention_run audit
row per run.
- retention_classes.py: PIA §9 data classes at their interim periods, all
approved=False pending YPMS-POAM-054. Classes without a PIA basis
(hosts, operational logs, accounts, consent-derived) are unset and logged
by name with their governing POA&M item. Vendored framework tables are
mapped by table name so vendored files stay unchanged.
- stub_models.py + migration 0004: id + mixin models for the 26 stub
entities so each can carry a policy. Migration uses a literal table list.
- ypms/models.py: single import-all module used by Alembic env, the job,
and the test fixtures.
- Drift guard: test upgrades a scratch SQLite DB to head and compares to
Base.metadata. Found pre-existing drift in 0002 (named unique
constraints duplicating the unique indexes on roles.code, users.username,
users.email); allow-listed, follow-up noted in PHASE0_STATUS.
156 tests passing; ruff + mypy clean.

Registrant model + schemas + router + migration 0003, exercising the
vendored framework end-to-end (CRUDService, RBAC, audit, version history).
- SSN app-layer encrypted (AES-256-GCM, HKDF key, column-bound AAD,
versioned format) in security/column_crypto.py; write-only on the model;
serializer exposes only ssn_masked (XXX-XX-1234). C.5.7.50 / SC-28.
- pii_read audit on GET, list (one row per page with ids), and history.
C.5.6.9 #5 / AU-14.
- Portal-only callers (YOUTH/PARENT/HOST) limited to own row via
Registrant.user_id; out-of-scope is 404. PARENT_USER sees nothing until
Guardian lands. History gated on VersionHistory, not View.
- minor_flag derived from dob at read time.
Framework changes (flag to OWC on re-vendor):
- crud._to_dict honors __audit_redact__, keeping ciphertext out of
audit_log and version_history.
- crud._to_dict serializes date (not only datetime) for JSON columns.
- CRUDService.history annotation uses builtins.list (method shadowed it).
98 tests passing, 94.83% coverage; ruff + mypy clean.

Brings in a working generic-CRUD framework plus its dependencies from OWC
(../owc-system/src/owc/, snapshot 2026-04-20). Every vendored module carries
a header comment naming the source; the OWC → ypms rename is the only
mechanical change.
Vendored modules:
- framework/base.py TimestampMixin, SoftDeleteMixin, VersionedMixin
- framework/pagination.py Page[T] with to_dict()
- framework/version_history.py Snapshot table
- framework/crud.py CRUDService with audit emission
- framework/bulk.py BulkOps (BulkResult / BulkUpdateItem)
- framework/router.py make_router() factory (kept without
`from __future__ import annotations` for
FastAPI type introspection — see the module
docstring)
- audit/models.py AuditLog
- audit/service.py record()
- security/models.py Permission
- security/rbac.py can() + require_permission() dependency
(DOES_SYSTEM_ADMIN as the super-role)
- users/models.py User, Role, UserRole (YPMS adds
mfa_verified and assurance_level; drops
OWC-specific claimant_id)
- auth/deps.py get_current_user() placeholder — real JWT
verify lands in 0.3
YPMS-specific additions on top of the vendored framework:
- framework/pii_audit.py emit_pii_read() — NIST AU-14 / source RFP
C.5.6.9 #5. OWC doesn't need this because
its case-management surface is staff-only;
YPMS must audit reads of minors' PII, SSN,
banking, FERPA-covered OSSE records, and
CFSA foster/ward flags.
Bugfix vs. upstream OWC:
- framework/crud.py Pagination `next_cursor` was previously the
peek-ahead row's id, which combined with
`where id > cursor` on the next page
silently dropped one row per boundary.
Caught by test_list_pagination_forwards_cursor.
Fixed here; noted in the module header so
re-vendoring OWC surfaces it upstream.
Migrations:
- 0002_framework_tables.py Baseline for users, roles, user_roles,
permissions, audit_log, version_history.
Immutable once merged per CONTRIBUTING.md.
- migrations/env.py Imports the new model modules so
autogenerate compares against them.
Tests (26 passing, 93.10% coverage, floor 80%):
- tests/framework/test_crud.py CRUDService lifecycle + snapshots
+ audit emission (7 tests)
- tests/framework/test_bulk.py BulkOps happy paths + failure
reporting (4 tests)
- tests/framework/test_pagination.py Page.to_dict serializer contract
(2 tests)
- tests/framework/test_pii_audit.py emit_pii_read row shape,
anonymous case (2 tests)
- tests/security/test_rbac.py can() + admin bypass + role union
(4 tests)
- tests/test_readyz.py /readyz smoke (1 test)
- tests/test_logging.py sanitize_for_log contract (3 tests)
Green locally: ruff clean, mypy clean (with a targeted override on
framework/router.py and framework/crud.py for TypeVar limitations that
OWC also accepts).
Advances YPMS-POAM-040. Prepares milestone 0.3 (JWT auth) and 0.4 (RBAC
seed) to plug into an already-live framework.
