# Blend mixnet: find the (hops, delay) regime where ONE uncle stops being enough.
# More relay hops and larger per-hop mixing delay push block visibility later -> more concurrent
# proposals -> more orphaned honest blocks per canonical block. A block can reference at most U
# uncles, so once the number of orphans per canonical block exceeds ~1, U=1 can no longer recover
# the full block density and the stake estimate stays low. This sweep brackets that transition.
# Latency is in SLOTS (1 slot = 1 s). Sweep axes (cartesian product x replicates).
