Thin wrapper over multiuser-doe.4th's own MU-EXEC-CAMPAIGN, which already implements the ratified 6-cell factorial generically -- adds only what FABRIC-3.md §XXXIV.4's per-ISA pivot needed: one fixed seed per ISA, N=3 reps/cell=18 trials/ISA (ratified over §XXXV.5's own N=2 safety-margin recommendation, Captain Bob's explicit choice), an ISA tag threaded into the trial marker so records from all 3 ISAs' sequential campaigns can be told apart on the shared disk/artemis.img, and three single-word no-argument entry points (RUN-AMD64-CAMPAIGN/RUN-AARCH64-CAMPAIGN/ RUN-RISCV64-CAMPAIGN). Blocks 5117-5119 -- the only 3 remaining in the [2048,5120) user block namespace; mkcapsule --lint caught the first draft going one block past the ceiling. Verified live, load-only: both capsules load with zero UNKNOWN WORD/redefinition/error lines, all 3 entry words resolve, constants compile correctly. No campaign trial has been run yet -- build+verify only, per explicit scope for this pass. FABRIC-3.md §XXXV.8/.9 records the decision and verification.

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.
