pub fn dominant_identifier(group: &CloneGroup) -> Option<String>Expand description
Best-effort name for the extracted function, derived from the most frequent non-generic identifier in the representative fragment.
Returns None when the dominant identifier is generic (data, result,
loop counters), appears only once, or ties with another, so absence is the
low-confidence signal for both human and agent consumers. This is a
lexical heuristic over the raw fragment, not an AST analysis; it is advisory
and consumers should verify before applying.
