Measured the expensive way. A reach-6 cluster showed open-open, so seed_ref
correctly reported 'no banked twin' for all six. I cracked the exemplar (203k
tokens, five new levers) and then drafted four siblings at ~60k each — including
one that had already burned 257k plateauing at permuter-class NEAR.
They were EXACT clones. The agents' own diffs said so: 'label-stripped .s diff vs
the twin is EMPTY', 'an EXACT clone (asm diff = labels only)'. The moment the
exemplar banked, seed_ref returned it as a banked twin for every sibling, and
family_remap + the §378 chain banks them for ~0 tokens.
The law: a bank CHANGES THE TWIN GRAPH. The twin oracle answers 'is there a
BANKED body like this?', so its verdict for every sibling is stale the instant the
exemplar lands. crack-wave-sweep-map-regen applied one level down — the family map
is not the only stale artifact, and the twin oracle is the one the cards read.
Also: never draft two members of one cluster in parallel; if either cracks the
other is free.
