# Lint config for the test tree, which ruff.toml excludes from `ruff check`.
#
# Deliberately one rule. F821 is the cheapest guard against a test that cannot fail:
# a name that does not exist raises NameError, and a test whose body is wrapped in
# `except Exception: pass` swallows that NameError and reports green. Widening this
# select list means ratcheting thousands of pre-existing findings, so new rules go in
# one at a time, each with its violations already fixed.
#
# No target-version here on purpose: it resolves from requires-python (>=3.10), so
# 3.11-only builtins like BaseExceptionGroup are correctly flagged in a tree that
# still has to run on 3.10.
