+        The document's changes, newest first: each with when (its writer's clock, Unix
+        ms; 0 for a remake's snapshot), the node that made it (`node`, its node ID) and,
+        for a write through the API, the user it was made for (`user`), and the store
+        paths it touched (a list's items by index). Every node holds every change, so
+        any node answers for the whole swarm, as far as it has synced; history before
+        the last remake is gone with it (`remakes.md`). Changes made before nodes
+        recorded their writers have neither `node` nor `user`.
