The two root causes behind what the reviews of the wait found, both in the code as it stands. Each with a check that failed first. EMIT stored its character and only then looked whether the buffer was exactly full. A flush that ended in a fault -- the stack too deep to begin a message -- left the buffer full, and the fault's own message was then put past its end, with (OUT^) never again at the end to be flushed. The 28 cells after the buffer happen to be unused, so nothing showed; the wait had put the ports there, and the node blocked writing to one. EMIT now sends a buffer it finds full before it stores. AWAIT, and (GATE) when a neighbour is writing, read a message's first word and then used stack that was not known to be there. With 27 or 28 values on the stack, or 28 or 29 calls deep, a line typed during AWAIT was taken and never answered. (ROOM) tries six cells and four return entries first: if they are not there the text ends 'Stack overflow' with nothing read. (GATE) tries the three cells its writing needs before a first word goes; it was safe before only by the order things were done. v4/tools/depthsweep.py runs every message path of the hosted product at every depth of both stacks: each line typed must be answered and the node must come back. hosted-check runs 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.
