Temporal evolution 3-seed: protocol fires at DFA epoch 3-4 on all seeds

  s42: (a)+(b) fire at epoch 4, DFA final acc 0.3076
  s123: (a)+(b) fire at epoch 4, DFA final acc 0.3203
  s456: (a)+(b) fire at epoch 3, DFA final acc 0.2998

BP never fires on any seed (final acc 0.61-0.63).

The 'protocol catches it 96 epochs early' finding is fully reproducible
across seeds.
