      # Non-blocking on purpose: the repo currently carries a pre-existing lint
      # baseline of ~60 errors (mostly import-order/unused-import findings from
      # incremental PR-by-PR development). Tighten this to a real gate (drop the
      # `|| true` and/or add `--exit-non-zero-on-fix`) once that baseline is
      # cleaned up — tracked as a follow-up, not a blocker for public release.
