Recovery

NineLives maintains durable session events and checkpoints.

Recovery behavior includes:

• restart reconciliation;
• uncertain-action detection;
• preserved isolated worktrees;
• session resume;
• manual checkpoints;
• isolated rollback;
• partial-output preservation after cancellation;
• lease-conflict handling.

Interrupted actions are not automatically replayed. When the runtime cannot prove whether an action completed, it marks the result as uncertain and requires review.

Resume

purrcode resume

Resumes a paused plan in the same session. purrcode resume --tui reattaches the terminal Workbench.

Rollback

purrcode rollback

Rolls back isolated work. Rollback requires an exact preview digest and explicit acknowledgement of any unattributed effects; invalid event append or replay fails loudly.
