family A: 64 points; family B (same seed): 64 points
reproducible: family(seed=0xABCDEF) == family(seed=0xABCDEF)  OK

first 3 points, seed 0xABCDEF vs 0x123456:
  #0: [6,21,0.9149]   vs   [2,10,2.8858]
  #1: [5,16,2.0410]   vs   [4,20,1.5472]
  #2: [3,10,2.7001]   vs   [8,22,2.4252]
seed-sensitive: family(0xABCDEF) != family(0x123456)  OK

wide-range probe: param-space slot 0 = idnode.k : I64
RandomSpace::new(full i64 range) accepted -> 8 points
points() over the full i64 range produced 8 points (no panic):

wide-range I64 sampler: no panic  OK

OK: reproducible + seed-sensitive; wide-range probe survived.
