  # SAST. Accepted rule exclusions (documented, minimal — never blanket):
  #   G104 — best-effort os.Remove/Close on error-cleanup paths.
  #   G204 — exec of gh / launchctl with internally-built args (no user input).
  #   G301 — staging/install dirs are 0755 (operator-readable install tree).
  #   G302 — extracted artifacts are executables and must be 0755.
  #   G304 — file paths derive from InstallDir / temp dir, inherent to an updater.
  #   G404 — math/rand used only for thundering-herd jitter, not for secrets.
  # G110 (decompression bomb) is FIXED in code (per-entry LimitReader), not excluded.
