Known-answer control for the deCIFer PXRD-to-CIF route, .xy format for direct route input. Simulated powder pattern of rock-salt NaCl (Fm-3m, a=5.6402 A), 2theta 10-90 deg, Cu K-alpha, Gaussian broadening + mild noise. Physics-verified peak positions (31.7/45.4/56.5/75.3 deg, sin-theta ratios 1:sqrt2:sqrt3:sqrt5) and 111 intensity. Supersedes the retracted Q-axis control (ce879116, buggy unit conversion). Same data as the 2theta CSV control (61729fcf).
