+  We use two thresholds:

+    T_enter (larger) : above -> allow direction change (set by sign)
+
+  Behavior:
+    If |diff| <= T_hold  : hold direction
+    If |diff| >= T_enter : set direction by sign
+    Else (between)       : hold direction
+
+  Presets (implemented as multipliers of the calibrated VdiffThreshold):
+    T_hold  = 1.0 * VdiffThreshold
+    T_enter = 2.0 * VdiffThreshold
+
+  Inputs derived from v1, v2: diff = v1 - v2
