Done adds project feedback and frozen receipts for agent work

Done’s [October 30 update](https://trydone.app/changelog) says recent grades and notes are read on the next task in the same project. Approvals graded 1 or 2 no longer count toward Full autonomy suggestions.

Approved agent work gets a receipt of the request, actions, proof and cost. It can be shared as a public link to a frozen copy, and that link can be revoked. The changelog reports context use, not demonstrated model training. Original map: recent project grades and notes inform the next task; public receipts are frozen copies of approved work, with revocable links.
