A ledger that survives

5 min read6 min readReviewed 26 October 2026

In short

A progress ledger is an agent programme's working memory: append only, one fact per line, evidence not claims. After a break, read the ledger, match it against the version history, check half-done work, then continue from the first unfinished task.

After this lesson you can

  • Write a progress ledger another agent can continue
  • Recover work from the ledger and version history after a session breaks
