feat(v4.0.0): the block words are the kernel's -- v3's way in full
Ruled 2026-10-07. BLOCK, BUFFER, UPDATE, SAVE-BUFFERS and EMPTY-BUFFERS are each one kernel request on port 0, by block number only. The node has a window of four slots in its memory, as a v3 VM has; the kernel copies blocks into it, keeps the record of which block is in which slot, and decides when a block is written (v4/system/blocks.c). The node keeps no record and gives the kernel no address, so a request cannot overwrite the node's code. When a block is written stays FORTH-79's: UPDATE marks it. When the chain of devices changes the slots are let go, as in v3. The window is 512 cells more than the two buffers were; the dictionary space ends that much lower, at 13824. MESH.md 8.5 had said, from the review, that a v3 VM's BLOCK is the kernel's buffer. It is not, and the section now says what was reported, what v3 does, and what was ruled. make -C v4 test, sanitize and hosted-check pass; amd64, aarch64 and riscv64 boot, POST 538 of 538, the same hashes on all six: logs/20261007-092835, -093112, -093456.
