nx_arousal_fit.nx

nx_arousal_fit.nx -- fits the perfusion time-constant tau to OBSERVED data by coarse-to-fine sweep over the shared nx_arousal_lib objective. This is the rung that lets the twin EXCEED the published literature instead of inheriting its ceiling: the orgasm/perfusion parameters rest on tiny old samples (Bohlen n=11, 1982), so the honest move is to make them FITTABLE, not fixed. Reports seed_residual alongside the fitted one so a run that did NOT improve is visible rather than silently reported as a fit. A fitter that always claims success measures nothing. usage: nx_arousal_fit tau <drive> <t1> <o1> <t2> <o2> [lo_ms] [hi_ms] nx_arousal_fit selftest license_tier: ORIGINAL expect_exit: 0
