- The result of every take is looked at: a wire cut between the look and the take leaves nothing acted on (the text before run again, a refusal counted, a wait ended by an old answer, a way forgotten). - A node with no room to pass on what another printed, or its word of how text ended, leaves it on the wire it came by and moves it when there is room; what is behind it for the same port waits too. Sleep for room (9) is woken by room on any of the node's wires (engine; MESH.md 7d.3). - The lone node's host keeps no queue for the kernel's port: a message to it is error 18. The step limit is counted while the node waits for room. - A text waiting for room to print is not interrupted by console text; AWAIT is, as before. (BREAK?) is gone. - A GONE is believed only by the centre's port; unawaited answers let go are counted; nothing past a message's last character goes on a wire; AWAIT sets (AWAIT-FROM) only once the stack has been tried. - test_host_depth.c: ten paths, each run works or ends in one named stack error; it fails with (ROOM) or (ROOM-SERVE) taken out.

FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
