Summary

Uncomment T20 (flake8-print) in the select list. print() calls in library code bypass log levels and pollute stdout — critical for a library consumed by downstream tools.

T201 remains in the unfixable list to prevent ruff check --fix from silently deleting print statements.

Existing violations will be addressed by a stacked compliance PR with noqa directives.

Summary by CodeRabbit

  • Chores
    • Updated code quality checks to prevent print() statements in library code.

Add T20 (flake8-print) to the select list. print() calls in library
code bypass log levels and pollute stdout. T201 remains in the
unfixable list to prevent silent removal of print statements.
Existing violations need compliance fixes (noqa directives).

A single line, a rule set free,
No more prints shall silently be,
Ruff now watches, sharp and keen,
Should we tidy stray debug lines too, wdyt? 🐇
