Function driver_candidates 

pub(super) fn driver_candidates(
    idx: &VolumeIndex,
    table: &OffsetTable,
    driver: &Driver,
    skip_excluded: bool,
) -> Vec<EntryId> 

Run a pool-sweep driver and return live (and, when filtering, non- excluded) candidate entries. Hits are validated against entry boundaries: pool bytes from renamed-away names (“stale gaps”) and matches spanning two names map outside their entry’s range and are rejected.
