# v17g next direction

Formal status: `v17g_reverse_closed_length5_move_qualified`.

Preregister v17h as an effect-blind matched accepted-edge-work start-memory gate. Compare the qualified old length-2-to-4 kernel with the qualified reverse-closed expanded kernel on the same six spaces and both frozen starts. Use independent seeds, stop each arm at the same accepted removed-edge work, and make absolute cross-start distance the primary response. Keep source spectrum and observed effects closed.
