## Simple Python lint for fm_shim_frontend.
##
## Scope is intentionally narrow:
##   - usr/lib/python3/dist-packages/fm_shim_frontend/  (the only
##     Python in this repo)
##
## Tools:
##   flake8 --select=F  Pyflakes-class checks only (F-codes:
##                      undefined names, unused imports, unused
##                      local variables, etc.). Skips PEP8 style
##                      (E/W codes) - the codebase uses '##' block
##                      comments which would trigger E266 noise.
##                      flake8 over plain pyflakes because pyflakes
##                      does not honor '# noqa' (the standard
##                      escape-hatch for intentional violations);
##                      flake8 wraps pyflakes and adds that
##                      support. Pylint was deliberately not
##                      enabled here because pylint's interaction
##                      with PyQt5 produces a flood of
##                      'no-name-in-module' false positives (PyQt5
##                      generates its symbols dynamically; pylint
##                      cannot see them statically without a
##                      per-symbol --extension-pkg-allow-list that
##                      defeats the simplicity of this workflow).
##
## Source files in this repo carry a '#<package-tag>' suffix per
## the genmkfile convention. pyflakes discovers sources by file
## extension; ci/codeql-prepare.sh creates extension-clean symlinks
## that re-use that fix.
