utils/file_length/_tables.py

"""Exemption tables for the 250-line file-length cap.

The data half: which extensions are capped, and which paths are generated,
vendored, third-party or session artifacts. :mod:`file_length.exemptions`
holds the rules that read these, and :mod:`file_length.config` re-exports
both as the public surface.

Duplicating these lists in shell is what lets a gate and a survey silently
disagree, so they live here once.
