Formal successor to §XII's ad hoc exerciser campaign, requested as a
genuine randomized full-factorial design matching this project's own
DoE methodology (capsules/doe.4th's Fisher-Yates shuffle), and written
entirely in FORTH per explicit request -- not host-orchestrated shell
scripting.

experiments/std79-doe/std79-doe.fth: builds a 27-cell (9 identity x 3
replicate) run matrix, Fisher-Yates shuffles it with a fixed seed
(matching doe.4th's own default), then dispatches each of the 24
exerciser test cases directly into the target identity's own live VM
via VM-EXEC -- no console USE redirection, no per-trial host
interaction. The zuse case runs as directly-compiled native code
(RUN-TEST-NATIVE) rather than VM-EXEC targeting "Hera" herself:
VM-EXEC's own vm_state_push/pop only saves rsp/exit_colon/ecw_nesting,
not input_buffer/input_pos, so a self-targeting call while this
capsule's own vm_interpret call is still mid-line would risk exactly
the class of bug the idle-tick reentrancy guards exist for.

amd64: all 27 trials ran with all 9 identities simultaneously live in
one boot -- clean, zero mismatches.

aarch64: hit a real, uninvestigated bug attaching all 9 simultaneously
-- the 6th live VM's birth stalled for 90+ minutes at 100%+ CPU with a
Stadium COOL-dispatch counter already at 335,000+ cycles, versus tens
of thousands at the same checkpoint for earlier identities. Not
root-caused here (flagged in FABRIC-3.md for later); worked around by
splitting into 3 boots of 3 simultaneously-live identities each, every
boot sharing the same seed so the master 27-slot shuffle is identical,
filtered per boot by a new ACTIVE-LO/ACTIVE-HI range
(EXEC-STD79-DOE's signature: seed lo hi -- ). run_id is always the
slot's true position in the master shuffle, so trial order stays
comparable across boots -- standard DoE blocking.

riscv64: same 3-boot pattern, clean.

Grand total: 81/81 trials correct, 0 mismatches, across all three
architectures, all nine identities, all three replicates.

Also flagged (FABRIC-3.md §XIV, not fixed): attaching several WIREBIND
identities near-simultaneously (whether via rapid hotplug or all
present from boot) causes the kernel to silently detect only some of
them -- confirmed at the host/QMP level that every device was genuinely
present. Worked around throughout this campaign by attaching one
identity at a time with confirmed waits; real hardware hotplug could
hit the same gap, so it's a genuine robustness concern, not just a
test-harness inconvenience.
