# Selected EXPLICITLY, not inherited from ruff's default. This used to be
# `ignore`-only, relying on ruff defaulting to E4/E7/E9/F — until ruff 0.16
# widened that default and the gate went from clean to 547 errors across the
# repo on a routine tool update. None of the 547 were E* or F* (i.e. no
# correctness findings): 189 blind-except, 85 import-order, 70 B008, 51
# subprocess-without-check, 30 try-except-pass, ~30 more families. Adopting
# them means a repo-wide reformat plus suppressions for zero bugs found, so
# the gate stays narrow — and now says so, independent of tool version.
# CI pins the ruff version too (.github/workflows/ci.yml); both are needed:
# this stops rule-set drift, the pin stops behaviour drift within these rules.

# churn in unrelated files. Correctness rules (F401 unused-import, F811
# redefinition, F821 undefined-name, F-string, E711/E712) stay ON.
