5-5: Consider removing the duplicatetypingimport at line 13.Since
typingis now imported at line 5, the second import at line 13 inside the try-except block is redundant. The module-level import at line 5 ensurestypingis always available.♻️ Consolidate typing imports
At line 13, you can remove the duplicate import:
try: - import typing - import typing_inspect # type: ignore[import-untyped]🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@src/bioetl/__init__.py` at line 5, The module-level import typing at the top makes the second import typing inside the try-except redundant; remove the duplicate import statement in src/bioetl/__init__.py (the one inside the try/except block) so the module uses the single top-level typing import and the try/except only wraps platform-specific imports or definitions without re-importing typing.

In `@src/bioetl/__init__.py`:
- Line 123: The __getattr__ function currently uses the overly-broad return type
typing.Any which loses information about returning module objects; update the
annotations to return types.ModuleType by adding a TYPE_CHECKING guard that
imports ModuleType only for static analysis (i.e., add "from typing import
TYPE_CHECKING" and under "if TYPE_CHECKING:" import ModuleType from types), then
change the signature of __getattr__ to return ModuleType so callers and type
checkers get the correct module type without adding runtime import overhead.

Type safety regression: typing.Any loses semantic information about module returns.
The return type typing.Any weakens type checking. The function returns module objects (types.ModuleType), and downstream code benefits from knowing this. Since from __future__ import annotations is active (line 3), you can preserve the accurate type hint without runtime import overhead using a TYPE_CHECKING guard:
🔒 Preserve type safety with TYPE_CHECKING guard
Add this import block near the top of the file (after line 5):
from typing import TYPE_CHECKING
if TYPE_CHECKING:
from types import ModuleTypeThen use the accurate return type:
-def __getattr__(name: str) -> typing.Any:
+def __getattr__(name: str) -> ModuleType:
"""Lazily expose top-level package namespaces for patch/import stability."""This imports ModuleType only during static analysis (not at runtime), preserving both type safety and the goal of minimal runtime imports.

🎯 What: Moved
import_moduleinto__getattr__and replacedtypes.ModuleTypewithtyping.Anyas the return type hint insrc/bioetl/__init__.py.💡 Why: This removes top-level standard library imports that are technically only utilized within the local module's
__getattr__lazily, thus addressing the code health goal of removing strictly "unused" top-level imports and making the file PEP-562 compliant for module-level__getattr__hints, all without removing critical side-effect imports likepandera.backends.pandas.builtin_checks.✅ Verification: Ran
uv run ruff check src/bioetl/__init__.pyto ensure no linting warnings exist. Ranuv run pytest tests/architecture/test_forbidden_imports.py tests/architecture/test_composition_factory_import_boundaries.pyto confirm no architecture import boundaries or tests are broken.✨ Result: A cleaner
__init__.pyfile without unused/stray top-level imports, adhering strictly to code health guidelines without compromising functional dependencies or validation checks.PR created automatically by Jules for task 16272366326348512427 started by @SatoryKono
