Point-in-time research metrics
A Continuity Receipt is a cryptographically verifiable statement that an observer collected sufficient evidence supporting the continuity of a subject over a bounded interval of time.
It is engine-independent: no sensor type, algorithm, or hardware requirement appears in the specification. The protocol standardizes how continuity assertions are represented, exchanged, and verified.
Research engines and verification studies are experimental research artifacts, not production components.
