Any identity could have arbitrary FORTH run as Zuse: KH-ELEVATE-SEND and KH-BLK-ATTACH-SEND sent any text to Hera, from any VM (shown live). And the drain popped a message after running it, so a payload calling a colon word ran twice. Both fixed test first (FABRIC-3 SXXXVII): - KH-BLK-ATTACH-SEND is ( dev-addr ok? -- sent? ), Artemis only; the kernel writes the reply text. BLK-ATTACH-ACK is Hera's only. - The drain pops before it runs. - Elevation, ruled not needed: KH-ELEVATE-SEND, message type 8, zuse-eligibility.4th, ZUSE-ELIGIBLE?/ZUSE-ELIGIBILITY-ADD/ ELEVATE-PUBKEY-UNPACK and the eligibility list removed; its disk area stays reserved, unused. FABRIC-3.7 closed. Three ISAs: POST 1052 passed; new parity baseline word_count=523 hash=0xb73b58052d591638 (deliberate). 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.
| 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.
