+## Units
+**All world coordinates are centimetres** (1 Three.js unit = 1 cm): anchor/spawn/building
+positions and sizes, wander radius, calibration readouts. Marker print size stays in mm
+(`sizeMM`); the mm→cm conversion happens once in `fuse.js`.
+
 ## Baked-in AR fixes (hard-won, do not "simplify" these)
-- **POS-IT pose**: rotation used **as-is**; translation **Y and Z negated** (`-t[1]`, `-t[2]`).
+- **POS-IT pose**: **raw** centered image coords into POS-IT (no Y pre-flip — pre-flipping
+  double-inverts the vertical axis and makes tilt respond backwards); rotation used
+  **as-is**; translation **Y and Z negated** (`-t[1]`, `-t[2]`). A/B toggle: `FLIP_INPUT_Y`
+  in `public/js/ar/pose.js`.
 - **Planar-ambiguity flips**: per-marker temporal consistency — pick the POS-IT solution
   closest to the previous frame (`public/js/ar/pose.js`).
 - **Phantom marker IDs**: `maxHammingDistance: 0` (`public/js/ar/detect.js`).
