-  (agent) Decided 2026-10-24 (docs/DESIGN.md); not built yet.
+  (agent) Bars now pile neatly: a bar that lands snaps into line, and one hanging mostly over a gap
+  tips into it, so piles have no air holes. For storage there's a new Bar rack block ($40) in the
+  Machines tab. Each block holds 50 bars of any kind; stack blocks in a column for more. Bars that
+  land on top go in, the hover shows the counts by kind, and F opens the gate at the bottom so
+  bars come out one at a time, oldest first, onto a belt below. Taking a block back gives its
+  bars to you. Please try a rack under an ingot mold's belt and see if the stacking feels right.
