continuous-integration/drone/push Build is failing
`scripts/lint.sh --fix` from the pinned lint devshell: 90 Python files reformatted (ruff format, mechanical) and one C420 (dict comprehension → dict.fromkeys) in tests/unit/test_f211_sso_skip.py. The push self-test had been failing at the lint stage since build 1313 (2026-08-31) on exactly these files; nothing else changed.
