Compatible transfer and finite precision

Thus channel closeness can transfer a fixed decoder on a correctly identified common interface. It does not install the decoder, grant forbidden access, or prove its laboratory calibration. Comparisons mixing physical $B$ into the receiver are not access preserving CheungHawk04D.

Haar matrices and the ideal decoder may have arbitrary real coefficients. Exact finite-alphabet compilation is not presumed. Finite-precision implementations belong to the allowance $\eta +\iota$.
