A node writing to a node that was stuck, and was then killed, stayed blocked for ever: killing a stuck node could cost its neighbours. And on the hosted and bare-metal products a write to an empty port, 5 7 PORT!, ended the program with "the node stopped". Now a node that can take an error, blocked writing to or reading from one port that nothing is wired to -- nothing ever was, or what was there has been killed or the wire cut -- has error 18, No one on that port, raised on it and goes on. A bare node waits as on the fabric; so does a node whose neighbour is asleep, and one reading "any port". test_host_unit.c: Hera kills node 14 while node 12 is blocked writing to it. It failed first: 12 stayed blocked. test_fabric.c: a bare node still waits. hosted-check types 5 7 PORT! and goes on; it failed first too. make -C v4 test, sanitize and hosted-check pass; amd64, aarch64 and riscv64 boot, POST 538 of 538, dict_hash 0x5f0a949a6fc8ef2b on all six: logs/20261007-121743, -122008, -122337.

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