 - `bootstrap`: emits at most 2 KiB of protocol navigation, never memory content.
 - `verify`: validates a recursively addressed causal tree and the 10-child limit.
+- `review`: reviews one leaf or the full tree for causal transitions, non-generic why, rejected-route reasons, and retrievable sources. It reports problems to the current model; it never writes memory itself.
 - `route`: ranks only the current node's child summaries and returns at most three paths.
 - `read-node`: reads one selected node with a hard byte limit.
