A block request with fewer than two values on the stack is refused; it had acted on whatever the stack ring held and stopped the node. Bare metal: when the kernel's chain takes the place of POST's block RAM the node's two buffers are emptied, so it no longer holds POST's copy of a block; and the chain's fast RAM is cleared, so a node cannot read what was in the kernel's heap. blocks.c is built with each test under that test's own warnings and sanitizers; it had been left out of both. The hosted link cleans its object directory first: it had linked the withdrawn store_v3.o left there from the day before. node.h and DECOMPOSITION.md D-19 no longer describe the message device or the four registers as current. MESH.md 8.5 records two findings for ruling: a node's own copy of a block, and a block read over a node's code. From a clean build: make -C v4 test, sanitize and hosted-check pass; amd64, aarch64 and riscv64 boot, POST 538 of 538, same hashes, blocks 1 and 2047 clean at the prompt: logs/20261007-085017, -085254, -085636.

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.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
