# Ruff configuration — pinned deliberately.
#
# Before this file existed the repo had no Ruff config, so `ruff check .` ran whatever the
# installed Ruff version enables by default (Ruff 0.16 turns on a very broad set). Findings
# were therefore not reproducible between machines. Never rely on tool defaults.
#
# Policy, decided from the measured findings:
#
#   * `select` is explicit: high-signal correctness rules first, then the mechanical
#     modernisation rules only.
#   * BLE001 is selected so existing reasoned suppressions stay *used* and RUF100 cannot
#     delete their rationale. Broad catches around Blender/environment probing are legitimate.
#     BLE001 is NOT part of the gate.
#   * S110 / S112 / E722 ARE part of the gate. The Blender scripts are the riskiest place for
#     a silent swallow: they run headless, so a swallowed error becomes a silently wrong or
#     missing artefact rather than a visible crash.
#   * B023 (loop-variable closure) matters here more than anywhere else in the workspace —
#     the geometry/patch scripts define callbacks inside loops over axes and signs.
#   * RUF100 is `unfixable`: a machine must not remove a suppression whose comment records
#     why it exists.
#   * The mechanical sweep never uses `--unsafe-fixes`.
#
# The gate selects the narrow set explicitly:
#
#   tools/lint_gate.py                     # the gate: changed files, machine-readable
