 Full architecture, task-authoring guide, the asset-gotcha table and the verification workflow:
 [`source/bimanual/yam/README.md`](source/bimanual/yam/README.md).
+Every non-obvious failure and the measurement that settled it:
+[`DIAGNOSTICS.md`](DIAGNOSTICS.md) — read this before debugging a new asset.
+
+### The one habit that matters
+
+When a grasp or a joint misbehaves, **measure the asset offline before touching a parameter.**
+Most of the hard bugs here looked like tuning problems and were not:
+
+```bash
+# where is the graspable part, and is the mesh origin even on the object?
+python -c "
+import trimesh, numpy as np
+m = trimesh.load('objects/083_brush/visual/base0.glb', force='mesh'); v = m.vertices
+tall = int(np.argmax(m.extents)); oth = [a for a in range(3) if a != tall]
+lo, hi = v[:,tall].min(), v[:,tall].max()
+for i in range(8):                      # cross-section along the long axis
+    s = v[(v[:,tall] >= lo+(hi-lo)*i/8) & (v[:,tall] < lo+(hi-lo)*(i+1)/8)]
+    print(f'{i/8:.0%}', s[:,oth[0]].ptp(), s[:,oth[1]].ptp(), 'centroid', s[:,oth].mean(0))
+"
+```
+
+That one command found the brush's 1 cm handle **and** the 3.7 cm offset between the mesh and the
+body origin that `object_pos()` reports — two separate bugs that both presented as `gap 0.0 cm`.
+The same check on the kettle found a 4.7 cm offset. For articulated assets, read the URDF's joint
+`axis` and `bounding_box.json` rather than inferring anything from the USD.
+
+## What actually works
+
+Honest status, regenerated from the run logs — not a wish list. A task counts as **passing** only
+when its numeric conditions pass **and** the rendered contact sheet was inspected and agrees.
+
+The numeric checks are deliberately strict, and three of them were caught *lying* during
+development (see [`DIAGNOSTICS.md`](DIAGNOSTICS.md)): a pour that reported success with a failed
+grasp, and two joints that "moved" on gravity alone. Each was tightened rather than worked
+around, so several tasks moved from green to red on purpose.
+
+Run `python scripts/status.py` to regenerate the table below from `outputs/tasks/*.log`.
+
