The flip: within each K-instrument chunk (the structural residency bound from the previous commit), all cells run concurrently on rayon's process- global pool — the same pool the engine's member/window fan-out already shares, so cells x members x windows feed one work-stealing scheduler and the per-cell serial seams (ingest transpose, single-threaded bootstrap) overlap with other cells' work. Results land in index-addressed slots and the ordered outputs are rebuilt in document order: byte-identical outcomes across worker counts and bounds (C1). Fault routing, restructured for a loop that cannot mid-iterate abort: member/window faults stay #272-contained inside run_cell; non-containable faults (incl. registry writes — infrastructure, not cell pathology) latch an atomic abort flag so unstarted cells never run, and after the join the lowest document-order fault among completed cells propagates as the run's error. Nothing partial is persisted at run level on the fatal path. Property pins: determinism across thread counts and bounds (1-thread/K=1 == 8-thread/K=2), distinct live instruments never exceed K (refcounting stub runner, 8-thread pool), a dead family store is run-fatal with no partial campaign-run record, member faults stay contained under the parallel loop. E2E fixtures (previous commit) pin the CLI prose and document-order persistence across K. Verified: workspace suite green, clippy -D warnings clean. rayon enters aura-campaign under the amended C16 per-case policy (comment in Cargo.toml, mirroring aura-engine). closes #277
