+The model pass took the pump from **1064 to 2412** triangles and raised
+the ceiling **2200 → 2600**. Two lighting-and-paint passes had left it the
+plainest object in its asset sheet: a smooth two-step column on a box. It
+now carries the cast detail a village pump has: a turned lower barrel with
+a moulded foot and a spout boss, eight flutes on the upper barrel, a
+moulded collar at the socket, a domed cap and ball finial on the head, a
+rolled drip lip on the nozzle, a counterweighted tail on the handle, and a
+turned grip. A coopered bucket with two iron hoops stands under the spout,
+clear of the plinth. The spout's reach grew 0.13 → 0.17 m (`SPOUT_R`) so
+the nozzle clears the plinth and falls inside the bucket mouth. The outer
+AABB grew in y (0.382 → 0.521 m) for the bucket and in z (1.052 → 1.055 m)
+for the finial. The collider stays under its 220 ceiling because its
+source turns the bucket at 8 staves without hoops (`BUCKET_PROXY_SEGS`); at
+16 staves the hull ran to 267, past Unity's 255 convex-collider limit. The
+foot (0.068 m) and spout boss (0.067 m) stay within `COL_R_TOL` of
+`COL_R_LO`, so the column-radius budget still reads the barrel. The flange
+classifier now also requires a shell centred on the column axis: the
+bucket's lower hoop is as wide and as low as the flange, and would
+otherwise mask `--float-flange`. The new **bucket** budget gets its own
+falsifier, `--shift-bucket` (exit 20).
+
+Earlier, base triangles dropped from **1164 to 1064** in the quality pass: seven
 sausage cylinders became one gooseneck tube, and the wood grip is no
 longer beveled with the plinth. Outer AABB is 0.610 × 0.382 × 1.052 m
 (was 0.610 × 0.364 × 1.049 m).
