Robert Allan JamesandClaude Opus 5.5 ac42cf36b5 Stage O-C: the event-driven DoE driver -- DOE returns to the prompt, EV-DONE chains the trials, MU-WAIT-ALL deleted (FABRIC-3.9.0 §3/§7.4)
- DOE sets up, JOINs EV-DONE and starts trial 1, then returns. Each trial
  births and sends WL-RUN only; completion arrives as the OS's EV-DONE.
- ON-DONE counts this campaign's own workers while active; the last one
  ends the trial (KILL all, marker, persist) and starts the next, or
  finishes (HB-OFF, UNJOIN, MU-CAMPAIGN: complete). MU-WAIT-ALL is gone;
  the start/end cycle goes through MU-END-XT.
- WL-DONE-ARGS removed from all ten workload capsules; lint passes.

Smoke campaign (amd64, 1 rep, rows off per Captain Bob): DOE returns, the
prompt answers mid-trial, all 6 trials chain on events, fail=0 each,
28/28 born/killed/departed, MU-CAMPAIGN: complete in ~61 min. Standard
sequence passes on all three ISAs (with the xHCI fix it exposed, df150e86).

Robert Allan JamesandClaude Opus 5.5 f152a91099 Stage H: DoE rebuilt on BIRTH/SEND/KILL, defs-only workloads; work heat floor on contact (FABRIC-3.8 §3.9, §3.13.7)
Workload capsules the DoE births are definitions only; each defines WL-RUN
(its old birth-time work plus its entry word twice) and WL-DONE-ARGS. The
driver births N workers, SENDs each 'WL-RUN WL-DONE-ARGS SEND', waits in an
ordinary loop for N MU-DONE messages, KILLs them (parked idle), and emits
the marker. The serialized VM-EXEC round-robin is gone.

Kernel: no switch checkpoint after a payload's last word; work heat is the
assessed per-beat charge, and a VM gaining work is raised to the busy set's
floor (Captain Bob's ruling) -- fixes a live stall where a busy-waiting Hera
never yielded, without serializing batch starts.

Evidence: cfg-4 rows spread evenly over Hera and all 8 worker slots (44k
switches); full cfg-4 trials on amd64/aarch64/riscv64 end fail=0 with 8/8
KILL dead; Stage G interleave byte-identical on all three. Acceptance:
dict_hash unchanged, relay 3, idle growth 0.

Robert Allan JamesandClaude Sonnet 5 94215e8b47 Fix two catastrophically heavy workloads found running the real campaign
Build / build-amd64-iso (push) Canceled after 0s
Build / build-aarch64-iso (push) Canceled after 0s
Build / build-riscv64-img (push) Canceled after 0s
The full 360-trial campaign was launched, then killed after 4h39m of
CPU time with zero trials completed -- still stuck on the very first
touch of the very first trial.

Root cause, quantified from the workload's own source, not estimated:
RUN-CHAOS5 (workload-5.4th) is 1000000 0 DO CHAOS-FIELD CHAOS-RIPPLE
LOOP, multiplying out to ~2.4 trillion word executions for one call --
~495 days at the observed rate. Never designed to be called to
completion as a single touch in a repeatedly-birthed worker.

A second problem found computing the fix rather than discovering it
mid-run again: workload-1.4th's own birth-time self-execution (20
SQUARE-WAVE + 1500 SQUARE-BURST + 100000x MICRO-BURST, all three run
automatically at capsule load) sums to ~875 million words -- ~4.3
hours just to birth one worker -- and worker index 1 always maps to
it in heterogeneous mode, landing in half the campaign's cells
regardless of concurrency level.

Fix: two new capsules, workload-1-lite.4th and workload-5-lite.4th,
carrying the same word bodies verbatim but a bounded self-execution
tail, comparable in scale to the campaign's other workloads. The
originals are untouched; only multiuser-doe.4th's own WL-CAPSULE/
WL-ENTRY index 1 and 5 mappings were repointed.

Verified live before relaunching a third time: the actual worst case
in isolation (5 0 998 MU-RUN-TRIAL, concurrency=8 heterogeneous,
includes both fixed workloads plus RUN-OMNI) completed in ~20 minutes
wall-clock, Hera stayed healthy throughout. Clean 3-arch qemu boot.

Reps reduced 60 -> 30/cell (Bob's call after seeing the real per-trial
cost) -- still matches the project's "rule of 3's" DoE convention
(same as ACL-RWT's own 30 reps). 6 cfgs x 30 reps = 180 trials.
