Direct answer
The ledger shows why a claim is supportable—or why it is not
This is a public claim index and change-history surface, not a compliance register. Every record keeps its claim class, support status, source identity, observation environment, verification method, scope, limitations, defeaters, and change lineage separate.
A repository source does not prove a deployed host. A target does not prove completion. An unavailable check is not favorable evidence. A hash proves byte identity within its stated scope, not factual truth.
