- Add _MixinBase abstract class to _helpers.py: declares _session(),
_deserialize_attacker(), _assert_pending(), _check_and_bump_version(),
and list_running_topology_deckies() so mypy can see cross-mixin contracts
- Add _require(val, msg) helper for narrowing T | None → T
- Inherit _MixinBase in all 26 leaf mixin classes
- Wrap SQLAlchemy column method calls (.is_(), .like(), .notin_(), .in_(),
.contains()) with col() from sqlmodel — fixes attr-defined false positives
caused by pydantic plugin typing class-level fields as Python value types
- Wrap select(Model.field) with select(col(Model.field)) for column projections
- Add pyproject.toml [[tool.mypy.overrides]] to disable arg-type in
sqlmodel_repo.*: pydantic plugin resolves .where(Model.field == v) as
where(bool), a false positive; call-arg still catches real argument errors
- Remove 9 stale # type: ignore comments (logging, helpers, credentials)
- Fix telemetry.py traced() overload no-redef + misc
- Fix logs.py datetime/str operator and nullable PK comparison with col()
- sqlmodel_repo/ now has 0 mypy errors
dict[str, Any] and X | Y union syntax require Python 3.10+. Containers
running centos7/ubuntu20/rocky9 base images ship Python 3.6-3.9 and
crashed on import. Adding the __future__ import makes all annotations
lazy strings, compatible back to Python 3.7.
Affected: templates/decnet_logging.py (+ all 22 template copies),
decnet/logging/syslog_formatter.py, decnet/logging/file_handler.py
