MESH.md step 4, the fault found there, as ruled (section 7a): a node writes only to a neighbour that is reading, keeps what it takes in meanwhile, and loses and counts what it has no room for. Engine: two more addresses after a node's ports -- which ports have a neighbour waiting to write to it, which to read from it. Nucleus: (GATE) before every message; the messages waiting, a ring of 400 cells, dealt with when the node is idle. Of two neighbours the lower number may wait to write (ruled after it was built); NEIGHBOUR tells a node who is on each port. test_host_mesh.c, 44 checks: the case that stopped the nodes passes; six messages from each node to each at once all arrive; 800 at once, the nodes come to rest and every message arrived or was counted (287 arrived, 714 of all kinds let go). test_fabric.c: the two looks. Both widths, ASan+UBSan. POST: twelve cases handed HERE, a cell address on v4, to words that take a byte address, and so wrote into or read from the nucleus's code at cell HERE/4. Ruled: left out, marked OPEN, until HERE and the byte words are made to agree as its own step. POST is 538 cases. hosted-check on three ISAs, 538/538. Bare metal: logs/20261006-134817 (amd64), -135044 (aarch64), -135440 (riscv64). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

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.
