rajamesandClaude Opus 5.5 2cf37aab4f fix(v4.0.0): step 6d after its review -- no error in the middle of the messages waiting, no offer left standing ...

Ruled 2026-10-08: A, B, C, D and the guard for a half message.  Each with
a scene in test_host_mesh.c that failed first.

A. The words of a message after its first are written from the passes
   over the messages waiting by (!W): an offer and a wait for that offer
   only (a new engine address).  A reader removed in mid-message makes no
   error; the rest is let go and counted.  Before, the error left the
   messages waiting in pieces and the node going round for ever.
B. A store to the wait withdraws every offer; (GATE1) and (PAY-SET) do it
   first.  Before, text begun after a node went round without sleeping
   could go to the port of an older offer: text for one node was done by
   another.
C. What a finished text printed is put with the messages waiting, as how
   it ended is.  With no room either is let go and counted; neither is
   begun as a message from (FINISH) any more, where a stuck node on the
   way held the whole node.
D. Only what a sender is owed from an earlier text -- its output, how it
   ended -- holds that sender's next text back; a GONE does not; and what
   cannot be noted holds nothing.  A node's own messages keep the order
   they were made in.
-  A message half taken in when its writer is removed is let go
   ((MQ-MEND)), not kept as if whole.
-  Smaller: a refused line no longer ends a waiting text 'Interrupted';
   a node's own queued messages may be passed on by 16 nodes, not 15; no
   value is left on the stack when a port goes in mid-refusal.

make -C v4 test and sanitize at both widths, hosted-check.
