Evidence limitation
A model hash is not subject identity
Direct limitation
It does not identify one runtime subject, memory history, authority set or continuing actor.
Artifact or claim that may be supported
A hash can identify exact model or artifact bytes.
What the evidence does not establish
It does not identify one runtime subject, memory history, authority set or continuing actor.
Additional evidence required
Multiple subjects can use the same model and one subject can change models.
Mitigation
Maintain separate subject, runtime, model, memory, key and continuity-event records.
Supporting sources
No public source record is assigned; the claim remains bounded by project doctrine, a governed report, or an explicitly unresolved evidence requirement.
