The final review of step 6e, by a fresh reviewer told to break it, and what was ruled: fix them all, test first. Each has a test that failed before the mend. - Two texts from one node could be begun in the wrong order when room for their answers came between the node's look at the first and at the second. Texts whose answers go by the same port are begun in the order they came: (D-MASK), quit.v4. 102 of 700 timings were wrong before. - A word written with PORT! to a node that speaks whole messages, or to a console's port, blocked its writer for ever and cut off every node beyond it. It is error 18 now, whether that node is asleep, running or stuck: fabric.c, node.c. - A node asleep for room on one wire is woken when another of its wires is cut. - A line there was no room for on the lone node's wire was reported as a fault and ended the hosted program. It is Message refused, and the prompt comes back: V4_BOOT_LINE_REFUSED. hosted-check has the case; no bare-metal boot has typed it. - Ruled: text behind held output for the same port is refused though it would fit. MESH.md 7d.4 said otherwise and is corrected. - The removal test also cuts and re-makes a wire, and has an exchange in which output is held at a full wire: 26,814 disturbances in all. - MESH.md and v4/README.md no longer say that a stuck node holds up no other node, that only printing waits, or that no node is left waiting on one that is gone; 7d.6 lists the limits and what the products do that they did not before. make -C v4 test and sanitize at both widths, hosted-check, lint. Three bare-metal boots: logs/20261013-194827 (amd64), -195131 (aarch64), -195518 (riscv64). POST 538 of 538, word_count=317, dict_hash=0xe5a57f3eb72ff94a on all six; the three sessions are the same character for character. The boots were built with the working tree's uncommitted change to kernel/Makefile that adds the ISA to the kernel's version line. 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.
