Function engine_files_for_sm 

Source 
pub(crate) fn engine_files_for_sm(
    engine_dir: &Path,
    sm: Option<&str>,
) -> Vec<PathBuf>
Expand description

Returns full paths of .engine files under engine_dir that match the requested SM, or all .engine files when sm is None.

Single source of truth for engine enumeration: every other function in this module that needs to enumerate engine plans (count, basenames, operator log line) delegates here. Centralising the filter is the design constraint behind the SM-aware refactor — a future caller that grew its own read_dir loop would silently regress the heterogeneous-SM safety invariant.

Failure modes (directory missing or unreadable) collapse to an empty Vec, mirroring the legacy count_engine_files behaviour and the “operator-visible, not load-bearing” stance of this module.
