@@ -78,6 +78,7 @@ Scripts using shared IMAP folder handling:
 - Default mode is dry-run; real moves require `--uitvoeren` and an interactive `JA` confirmation.
 - Account selection is explicit with `--account <naam>`; use `--account backup` for the disposable backup mailbox. The script prints both the config account name and mailbox address before connecting.
 - `--audit` is available only in dry-run mode. It suppresses per-message dry-run lines and prints planned move counts grouped by source folder and destination folder for step 2 and step 3.
+- Long scans show progress counters: source folders are printed as `[current/total]`, and audit mode prints `Gescand: processed/total` every 250 messages and at folder completion.
 - IMAP `LIST`, `SELECT`, `UID SEARCH`, and `UID FETCH` aborts are logged and retried once after reconnecting. If reconnect also fails, the script records an `ABORT`/`ERROR` in `verplaats_log.json` instead of printing a Python traceback.
 - `MAP_RENAMES` is intentionally empty.
 - Source folders are selected by shared `list_folders()` plus `mail_routes.is_source_folder()`.
