Logs

Conversations are saved in Inspect format to logs/. View with:

Copyinspect view --log-dir logs/

Session Checkpoints

Session checkpoints are JSON files saved to sessions/ by default. They contain:

• Path to the associated .eval log file

Use checkpoints to:

• Resume interrupted sessions
• Branch conversations from a specific point
• Archive sessions for later reference
