ADR 0005 first production slice: construct classification, refusal of raw-proportion Pearson, CPU f64 OLS and plausible-value loading recovery, invariance-gated mean comparison, and causal-heuristic refusal. No new migration.

…n T and strong means Stacked on #49 psychometric_core. Not a second invariance crate. Not DSEM, RI-CLPM, MGCFA, or Mislevy PVs. - CWC within/between OLS and Kish ESS WLS (Enders & Tofighi, 2007; Curran & Bauer, 2011; Hamaker et al., 2015; Kish, 1965) - Event-time discrete lag-1 and exact scalar log-rate a = ln(φ)/Δt (Voelkle et al., 2012, Eq. 7; Driver et al., 2017, Eq. 3); difference quotient refused - CWC-then-event-time residual lag, still not DSEM - Rubin T_m = Ū_m + (1+1/m) B_m on draw-level OLS loadings (Rubin, 1996, p. 473) - Two-group OLS latent means only under strong/strict; metric/weak is not enough. #84 metric licenses shared metric meaning only.

Summary
ADR 0005 first executable slice. No new migration (
