- Added new ignores from flake8-bugbear (`B007`, `B008`) - Ignored `C901` (high function complexity) for now, pending review - Maintained PyTorch conventions (`N812`, `N817`) - Allowed `E731` (lambda assignments) for flexibility - Consolidated existing ignores (`E402`, `E501`, `F405`, `C408`, `N812`) - Documented rationale for each ignored rule This keeps our linting aligned with project needs while tracking potential fixes.
