Function enumerated_identity_confidence 

pub fn enumerated_identity_confidence(present: usize, total: usize) -> f32

Identity as an enumerated state ([[principle-identifiers-not-identity]]): its confidence is the share of its total cryptographic anchors (identifiers + related datasets) currently present. One identifier of many → low confidence; the full enumerated fabric → high. 0.0 if total == 0 (an enumeration of nothing is not an identity).
