transfer constructed fixed schedule half logarithm samples to any supplied finer dyadic root at the same index preserving all positive normalizations and both finite errors

None of these finite arithmetic statements closes an IR campaign parent. The analytic identification, interpolation and final positive irrationality certificate remain open.
