RCP-CWK-003 Cowork Mid-Session Checkpoint
The AI captures a snapshot of your session progress so far — what you have accomplished, which files were touched, and your current priorities. It writes this as a partial handoff to your chat history file (or updates an existing partial if one already exists from an earlier checkpoint). A lightweight validation confirms the checkpoint data matches actual git state. Then it creates a git commit so the checkpoint is recoverable even if the session ends unexpectedly.
