Infratier Closure Physics - Tilt and Twist Costs in Frame Compression

The spin-selection theorem leaves two coefficients free. We derive their ratio from a proposed law for which small changes of an ordinary spatial frame contribute to compression. A phase reference records twist about a marked axis. A second coupling can give extra weight to changes of that axis under tilt. Let be the ratio of the squared responses to a tilt and a twist through the same angle. A maximum-entropy distribution at fixed mean response and a uniform distribution below a fixed response threshold both give a tilt-to-twist coefficient ratio of in the small-step generator. A single spin-one-half doublet then decays most slowly precisely when . Both the response ratio and the step distribution can be measured before testing for spin. The sampling law and access to the spinor lift remain physical hypotheses.
