+# Anomalous-accuracy scoreboard: score a jfjoch anomalous merge against XDS on the HEWL S/Cl
+# anomalous signal. Accuracy (not just precision): ANODE puts the anomalous density peaks at the
+# model's real anomalous atoms, and the peak height (sigma) is how strongly the data sees them.
+#
+#   ./anomalous_scoreboard.sh <jfjoch_anomalous.hkl> [label]
+#
+# <jfjoch_anomalous.hkl> is a jfjoch `--scaling-output txt` file produced with -A (anomalous):
+# whitespace-separated "h k l I sigma [rfree]". Prints <d"/sig> per shell (SHELXC) and the averaged
+# anomalous peak height at SD_MET / SG_CYS / CL_CL for the input vs XDS, with the XDS/input ratio
+# (1.0 = matched XDS). The XDS reference is computed once and cached (delete .anom_xds_cache to redo).
+#
+# The SHELX binaries are run under qemu-user because this WSL2 kernel sets vsyscall=none, which the
+# old static SHELX builds need (otherwise they exit 174 silently). Paths are overridable via env.
+# (No set -e/-u: sourcing CCP4's setup trips -u, and many greps below legitimately find nothing.)
