Write the archive to a .tmp file then rename into place so a concurrent prune can never delete a half-written archive, and run prune.sh after every save: keep the 3 newest archives per key-prefix family, expire anything older than 7 days, hard-cap the store at 2 GB (oldest first, trumping the keep set), never touch files younger than 1h, and drop stale run workspaces under ~/.cache/act older than 2 days.
