After deskew, horizontal text lines are already straight (~0° slope). Method D was measuring this (always ~0°) instead of the actual vertical shear (column edge drift). This caused it to report 0.112° with 0.96 confidence, overwhelming Method A's correct detection of negative shear. New Method D groups words by X-position into vertical columns, then measures how left-edge X drifts with Y position via linear regression. dx/dy = tan(shear_angle), directly measuring column tilt.
