# History

> Search the record of chats, terminals, commits, PRs, lane changes, proof, and checkpoints.

History answers the question: what happened in this project?

It records sessions, commits, lane changes, PR events, proof artifacts, checkpoints, and worker activity. Use it to recover context, audit agent work, or pick up where a session ended.

## Search and filters

Filter by lane, event type, date range, agent/provider, PR, or worker. Search text includes titles, summaries, command output snippets, commit messages, and PR metadata.

## Checkpoints

Checkpoints are useful moments in a lane's timeline. They let you inspect what changed around a session or commit and, when needed, branch new follow-up work from that point.

<Note>
  History is local project evidence. It is meant to make agent work inspectable, not to replace Git history or GitHub review.
