pub fn orbit_representatives(n: usize, generators: &[CubeSym]) -> Vec<Corner> ⓘExpand description
Orbit partition of the 2ⁿ corners under a set of generators, each a verified automorphism.
Returns one representative per orbit (the orbit-collapsed corner set the cover check needs).
Materializes a 2ⁿ seen-bitmap, so this is itself bounded by the hypercube size — it measures
the collapse rather than escaping it; the counting/parity shadows are what decide totality
without the 2ⁿ walk. Honest by construction.
