Module snapshot 

A run that stopped, in a form that can be continued.

Everything an interrupted run held that the rest of it needs: the inputs, every binding in scope, working memory, the outputs produced so far, and the counters. It is a JSON document a person can read, and that is a requirement rather than a convenience — it is what rules out serialising a continuation, which in turn is why only a top-level checkpoint is resumable. See RFC-0018 §4.

What is deliberately absent

Persistent memory. It belongs to the agent, not to the interrupted run, and both halves read and write the agent’s store as normal.

A cassette. A resumed run is given one the same way the first half was. Copying the recording into the snapshot would make the two disagree the moment either was re-recorded.
