Source notes and corrections
Source H unit scale is unresolved; not a normalized warping constant.
Source d, ratios, u, x and classifications are retained for reference only, never used for substitution.
Page 32 repeats inconsistent d and slenderness values in 39 rows; no guessed corrections.
Imperial d is labelled mm in the PDF; no inferred unit correction.
