MESH.md step 4. Each node has a table of destinations and the port toward each, and a port for everything else (ROUTE, DEFAULT-ROUTE, NO-ROUTES). A message not for this node is passed on whole; one with nowhere to go is dropped and counted. What text prints and how it ended go back to the node it came from by the same table. SEND sends text to another node. test_host_mesh.c: three StarForth nodes in a row behind a console, 28 checks at both widths and under ASan+UBSan. hosted-check on three ISAs. Bare metal: logs/20261006-115225 (amd64), -115501 (aarch64), -115849 (riscv64). NOT DONE. Two neighbours that write to each other at once wait for ever: a write blocks until the neighbour reads, and a node that is writing is not reading. The last check in test_host_mesh.c shows it (KNOWN FAULT). MESH.md section 7a sets out the ways out; none is chosen. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
capsules/
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.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
