Two healed hemispherical emitters at y=±d/2 radiate forward. We compute detector intensity at x=L by coherent sum and compare measured peak rows to analytic maxima rows. Fixes in this version: removed a stray duplicate block that caused a syntax error, unified pixel coordinates, filtered to in‑frame maxima, side‑aware matching, adaptive thresholding, and optional phase‑spaced fronts.
