Found in the five-node test, each with a check that failed first: - A node with answers it could not give to two stuck senders began no text at all. It now holds back only text from a sender whose own answer is still with it. - KILL waited to tell a stuck node, and a typed line that broke it left the nodes after it untold. GONE is put with the messages waiting, as how text ended is, and goes when it can. - So that 'tell, then wait' still works, AWAIT does what (IDLE) does but for beginning text: it looks through the messages waiting, offers what is to be passed on and what is owed, and sleeps in the wait. A waiting node no longer keeps back what passes through it. - A node in the wait with an offer on a port that turns out to have nothing on it is woken and told so (which port: 2 * V4_PORTS + k); no error is raised on it. (GATE) makes it error 18; (IDLE) and AWAIT let the message go. Before, removing a node raised 'No one on that port' on the unrelated text of a neighbour that had something queued for it. make -C v4 test and sanitize at both widths, hosted-check.

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.
