From 5812e0599ab6e3119bef670410c1c36ac8035576 Mon Sep 17 00:00:00 2001 From: CleverThis Date: Sun, 19 Apr 2026 13:21:06 +0000 Subject: [PATCH 1/3] [AUTO-INF-3B] features/environment.py uses # type: ignore comments in _install_fast_sleep_patch() violating CONTRIBUTING.md strict typing policy Removed 6 `# type: ignore` suppressions from `_install_fast_sleep_patch()` in `features/environment.py`. Used `cast(Any, module)` + direct attribute assignment instead of `setattr()` (which ruff B010 disallows) and `# type: ignore` comments. Added `from collections.abc import Callable` and `from typing import cast` imports. Added new feature file `features/test_infra_sleep_patch.feature` with 4 scenarios verifying the behavior. Added new steps file `features/steps/test_infra_sleep_patch_steps.py`.
