+    #197 (synchro TikTak) : chaque entrée fichier expose aussi ``size``,
+    ``mtime`` (epoch) et ``mtime_iso`` — un client externe peut détecter les
+    fichiers modifiés depuis un horodatage en **un seul appel**, sans relire
+    chaque fichier. Les valeurs viennent de l'index (source unique, même
+    contrat que ``list_all_files``) ; les répertoires portent ``None``.

         vault: Vault name.
         limit: Maximum number of entries returned.
