- 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.

Step 6e, tasks 2 and 3 (docs/v4.0.0/MESH.md 7d). The nucleus puts, looks
at, takes, moves and drops whole messages through the six addresses after
its ports; its own ring of messages waiting, the refusals owed, (GATE) and
the looking words' use are gone. SEND, an answer, a NACK and a GONE go or
are refused at once; what a text prints waits for room; a text is not
begun until the wire its answer goes by has room for it, and that room is
kept. The lone node's host (v4/system/boot.c) keeps its two wires and
does its operations; the test hosts' consoles put and take whole messages
through the fabric. New: tests/test_host_depth.c, every message path of
a mesh node at every depth of both stacks.
