# *.sage.py is generated by `sage --preparse` from *.sage sources.
# - F403/F405/F821/E741: Sage's runtime injects hundreds of globals (ZZ, var,
#   matrix, LatticePolytope, ...) via `from sage.all import *` before
#   executing these files, so plain static analysis can't see where names
#   come from.
# - E402/E702/I001: Sage's preparser itself emits an import-then-semicolon-
#   joined-constants preamble (e.g. `_sage_const_1 = Integer(1); ...`) ahead
#   of the file's own imports; that's Sage's boilerplate, not this project's
#   code style.
# - W291/W293: the preparser replaces every integer literal with
#   `_sage_const_N ` (trailing space included) to preserve token boundaries,
#   so trailing-whitespace warnings fire mechanically on almost every line
#   with a number in it -- not something `ruff format` could fix anyway,
#   since it wouldn't change the .sage source that generated it.

# Polytope/ToricPolytope/etc. come from the loaded file.
