Checkpoints and resume

JoyMux checkpoints bind integrity over session, client, lane, correlation, terminal state, and event cursor (joymux.checkpoint.integrity.v1).

Resume modes:

• EventReplayOnly — replay durable events; do not claim live PTY reattach after restart
• RestartRequired — work must be restarted
• NotResumable — no continuation

ask --approve --request-id <id> resumes a pipeline checkpoint that was waiting for approval without re-inferring natural language. Checkpoints do not expand privileges across clients.
