129 of 154 endpoint codes have at least one main ancestry link; 25 still need a distinct predecessor. A documented link may be qualified and does not complete every earlier stage. No endpoint is declared de novo.
The inherited scope maps to 153 currency identities. This is a complete graph-coverage check, not a fresh independent review of every existing historical claim.
