// Cross-file callback helper: invokes its callback argument on the data.
// When cross-file inline fires for this body at the caller site, the
// callback arg at the caller (`child_process.exec`) is visible to the
// inline re-analysis —
// its summary's `param_to_sink` kicks in, so the taint flow from
// `process.env.USER_CMD` surfaces a finding.

    return fn(data);
