 ## Behavior notes
 
+- `counters` holds the values of `number` counters whose definition is
+  `client_visible`; hidden counters are left out. Currency counters are in
+  `wallets`, not in `counters`. Counter changes bump the `profile` revision.
 - Warmed automatically at login (with catalog).
 - Kept fresh by the revision poll; call `reload()` after a module function
-  that mutates wallets.
+  that changes wallets or counters.
 - All fields are optional on the wire (`?`); code defensively.
 - React: `useSyncExternalStore` maps directly onto `onChange` (see the SDK
   README "React recipe").
