Convergent validity: AVE in [0.564, 0.658] — all exceed 0.50 threshold. Discriminant validity: HTMT ratios in [0.487, 0.612] — all well below 0.85 threshold, dimensions are empirically distinguishable. Aggregation-method robustness: rank correlation >0.93 against two alternative aggregation schemes. Bootstrap uncertainty: mean 95% CI width = 6.84 points on the 0-100 re_score scale — rankings are stable under plausible weight perturbation. External validity: moderate-to-strong correlation with three independent third-party indices (V-Dem, Fraser EFW, WIPO GII proxy), all in the theoretically expected positive direction. CAVEAT: as documented in methodology-scheme.html and oecd38-re-index.html, the underlying raw data series themselves (WDI/WGI/QoG downloads) were NOT re-executed for this archived log; the numeric values above are the authored, internally-consistent worked example that this download package's script suite is designed to reproduce when run against a live data-acquisition environment. See README.md for the provenance statement covering this entire downloads/ package. ================================================================================
