Baseline was 207 diagnostics. Two real bugs were hiding in the noise:
- tools/run_destructive_tests.py imported ctypes.wintypes at module scope,
which raises on non-Windows, and called fcntl unconditionally. The Windows
and POSIX implementations now live under a module-level sys.platform split.
- tests/ui/test_sources_page.py constructed Source(...) without document_id.
Structural fixes, not suppressions:
- New src/transcription/db/loading.py owns the SQLModel-field to
QueryableAttribute reinterpretation via orm_attribute()/selectinload()/
defer(). This removed 42 "# pyright: ignore[reportArgumentType]" comments
across documents/jobs/people/sources. Its docstring records that
selectinload(A.b, B.c) is NOT equivalent to the chained form: varargs
applies the selectin strategy only to the last path element, which under
lazy="raise" raises InvalidRequestError at render time.
- db/session.py transaction_scope no longer accepts or yields
AsyncSessionTransaction. No caller ever passed one, sessionmaker.begin()
yields an AsyncSession, and the dead branch was latently buggy because
services call .exec(). Cleared 7 workflows.py diagnostics.
- services/registry.py RegistryService is bound by a new RegistryEntry
Protocol instead of bare SQLModel, so the shared implementation can read
id/label/normalized_label/is_active. Cleared 9 diagnostics.
- Column expressions in sources.py/jobs.py/test_store.py wrap in sqlmodel
col(), the idiom already used in registry.py.
- read_source_navigation wraps its literal tuple bounds in literal().
- normalization.py narrows with isinstance(image, TiffImageFile) rather than
comparing image.format, since tag_v2 is TIFF-only.
- linked_people.render uses @ui.refreshable_method, the NiceGUI API for bound
methods.
- The OpenRouter capturing client re-raises ResponseNotRead when the response
stream is not async rather than mis-wrapping it.
Tooling gate:
- New .pre-commit-config.yaml runs ruff check and ty check as blocking hooks.
No pre-commit config previously existed. Negative-tested: injecting a type
error fails both hooks.
- The last two "# pyright: ignore" comments (config.py) are removed; ty does
not honor pyright directives. One "# ty: ignore" remains, in
tests/test_prompts.py, where the test deliberately assigns to a frozen
field to assert ValidationError.
- asyncio_default_fixture_loop_scope is pinned to "function" so
pytest-asyncio behavior does not shift on upgrade.
Verification: ruff check clean, ty check reports 0 diagnostics, 292 passed
and 4 skipped, pre-commit passes and demonstrably fails on a regression, and
tools/run_destructive_tests.py runs on Windows.

Removes the duplicated registry CRUD, the hand-written not-found raises, and
the three divergent media writers. Behavior is preserved: every existing
Document Type and Person Role test passes unchanged, which is the primary
proof for MED-11.
[MED-11] Generic registry service
- New services/registry.py owns RegistryService[ModelT]: list, list with
counts, create with IntegrityError -> conflict mapping, read, update,
delete with built-in and referenced guards, is_referenced, and label
normalization/casefold keying.
- DocumentTypeRegistry and PersonRoleRegistry declare only the model, error
class, noun, short noun, retainer phrase, and reference columns.
- DocumentService and PeopleService keep their public method names and
delegate. Every user-facing message, error category, and suggestion string
is reproduced verbatim; only the noun is templated.
- Deleted _normalize_registry_label, _document_type_label_key,
_normalize_role_label, _person_role_label_key,
_document_type_is_referenced, and _person_role_is_referenced.
[MED-12] Shared not-found lookup
- ServiceBase._get_or_raise(model, id, *, session, error, noun, suggestion,
options) loads by primary key or raises the caller's error type.
- documents.py: local _get_document_or_raise deleted; replaced by _read_document
and adopted at read_document, delete_document, and set_document_type, which
previously bypassed the helper and hand-wrote the raise.
- sources.py: 8 identical Source raises and 1 Job raise collapsed into
_read_source / _get_or_raise.
- jobs.py and people.py already funneled through local _not_found builders and
were left alone.
[MED-13][MED-01] Single media writer
- New services/media_storage.py owns validate -> name -> mkdir -> write ->
wrap OSError. The write runs in asyncio.to_thread, so uploads no longer block
the event loop.
- store_source_file, store_person_portrait, and store_homepage_image now share
it and are async. Callers in store.py, people_page.py, and home_page.py await
them. mkdir failures are now also translated to a domain error instead of
escaping as a raw OSError.
- homepage_store gains HomepageStorageError so its write reports like the others.
[MED-14, partial] Service independence
- New services/source_media.py owns SOURCE_MIME_TYPES, SOURCE_EXTENSIONS,
lookup_source_mime_type, and supported_source_formats.
- documents.py no longer imports services/sources.py. Its print projection uses
the non-raising lookup and raises DocumentError, so DocumentService no longer
emits a TranscriptionError.
- api/v4_print.py imports the mapping from the policy module.
- store.py and workflows.py still import sources.py; both are orchestration
modules, which services.instructions.md:75-77 explicitly permits.
- Splitting SourceService itself remains deferred to V4.7.
[LOW-08] Query shape
- list_sources_detail filters job_id with a JOIN on JobSource instead of
loading every Source and filtering in Python.
- read_source_navigation replaces the full ordered-id scan and .index() with
two row-value comparisons bounded by LIMIT 1.
- list_processing_artifacts gains the limit parameter its summary sibling
already had.
- build_evidence_export runs artifact integrity hashing and file reads through
asyncio.to_thread.
Tests
- tests/test_service_boundaries.py: AST guard asserting no service module
imports a sibling service module, plus a guard that the scan is non-empty.
- tests/services/test_transcription_service.py: asserts the job_id filter emits
a JOIN, and that navigation emits exactly two LIMIT queries.
- tests/services/test_store.py: the two storage tests are now async.
Verified: 276 passed, 4 skipped; ruff check clean.
