CrossRelay

The CV relay reduced to a point-to-point link, and to its own covariance

Test	What it does	Result
test_relay_covariance	cvmdi_point's conditioned four-mode spectrum converges onto cvmdi_rate's closed form as $1/V_A$, the two sharing no code past the arguments.	✅ pass
test_relay_limit	With a lossless encoder arm cvmdi_rate(1, T) equals the infinite-modulation trusted heterodyne rate at T, extrapolated as (10*K(1e8) - K(1e7))/9.	✅ pass
test_relay_scaling	A finite-modulation link falls short of the relay's asymptotic value by a gap dividing by ten per decade of $V_A$.	✅ pass
