+- **A-209** (design 46 approval mark §13, §677, §73; principles 3 and 7) A digest in a key is escaped with mesh-sdk's
+  `keys.EscapeName`, the one escape form for every name in a key, in both gates: `<node>.act.<escaped digest>`. The
+  kind (a test's in-memory state accepting a key the bus refuses) is fixed where it lives: mesh-sdk's in-memory state
+  for tests refuses every key the bus would.
