Outstanding flake8 findings (manual fix required)

1,173 findings remain — none are auto-fixable by black/isort. Breakdown by error code:

Code	Count	Description
E501	737	Line too long (> 88 chars)
F401	330	Imported but unused
F841	51	Local variable assigned but never used
F541	19	f-string without placeholders
F405	14	May be undefined from star import
E402	8	Module level import not at top of file
F811	7	Redefinition of unused name
F403	5	Star import used
F821	2	Undefined name

These require manual attention. The most impactful quick wins would be addressing F401 (unused imports) and F841 (unused variables).
