+### Hand-item fit on the Quaternius rig
+
+The hand attach point moved from Godot y 0.78 (procedural wrist) to **y 1.017** (Quaternius
+wrist), so `fit` measures hand gear against the new wrist instead of the authored attach offset.
+Run `blender_assets.py fit`; per item it reports the grip drop, the lowest point at rest, whether
+that clears the hip line (0.95) and `size_vs_head` — the proportion that makes "reads oversized"
+measurable on the 0.20 m head.
+
+| Item | Drop (m) | Lowest at rest | Clears hip | Longest | × head |
+| --- | --- | --- | --- | --- | --- |
+| `camera` | 0.053 | 0.964 | yes | 0.138 | 0.69 |
+| `phone` | 0.105 | 0.912 | no | 0.150 | 0.75 |
+| `cup` | 0.110 | 0.907 | no | 0.142 | 0.71 |
+| `radio` | 0.108 | 0.909 | no | 0.203 | 1.01 |
+| `flashlight` | 0.077 | 0.940 | no | 0.243 | 1.14 |
+| `wand` | 0.125 | 0.892 | no | 0.400 | 1.87 |
+| `umbrella` | 0.201 | 0.816 | no | 0.900 | 4.48 |
+| `clipboard` | 0.375 | 0.642 | no | 0.305 | 1.63 |
+| `protest_sign` | 0.250 | 0.767 | no | 1.230 | 6.12 |
+
+Falling below the hip line is normal for a carried object; the number that matters is whether the
+item was *authored* for the new grip. Only the `clipboard` was: its grip sat in the middle of the
+board, so it swung through the thigh. It now grips the top edge (0.22 × 0.30 m) like a carried
+clipboard, and `HAND_ITEM_AUTHORED_SIZE` in the tool flags any future drift past 10 %.
