cp, hamu, json, sqdt, thdif, visc

Purpose

TEMP_MOD holds physics at each shell for rotational mixing: specific heat, mean molecular weight, a density derivative, and the radiative diffusivity and viscosity. Shared by 5 routines. It replaces COMMON/TEMP/ (MHP via Claude, 10/14/26); JSON comes from DIMENSIONS_MOD.

What its variables hold, who sets them, who reads them.

CP, SQDT (JSON each): $c_P$ and $\partial\ln\rho/\partial\ln T$ (QCP, QDT), and HAMU(JSON): the mean molecular weight of a fully ionized gas, set by PHYSIC. CP is read by VISCOS, HAMU by GETW.
VISC(JSON): the viscosity, radiative plus molecular, and THDIF(JSON): the radiative diffusivity $16\sigma T^3/(3\kappa\rho^2 c_P)$, set by VISCOS.
All five are read by HPOINT and MIDMOD, HPOINT saves them as the values at the start of the step, and MIDMOD interpolates between those and the current ones.

Design

A blanket USE TEMP_MOD in each routine.

That matches COMMON's semantics. 19 MODULE TEMP_MOD 20C 10/20/26 MHP via Claude 21C code changed to take JSON from DIMENSIONS_MOD instead of declaring 22C a PRIVATE copy here. 23 USE DIMENSIONS_MOD 24 25 IMPLICIT NONE 26 SAVE 27 28 REAL*8 :: CP(JSON) 29 REAL*8 :: HAMU(JSON) 30 REAL*8 :: SQDT(JSON) 31 REAL*8 :: THDIF(JSON) 32 REAL*8 :: VISC(JSON) 33 34 END MODULE TEMP_MOD
