The violet layer is the anticipation inventory a level-loaded plan carries: it builds where the green line runs above the blue bars and drains through the peak. Policy-implied — no on-hand feed exists to track the actual position against it.

Anticipation stock = run rate × Σ(seasonal index − 1) over above-average months; seasonal max = safety stock + anticipation stock. All engine-recommended — the workbook snapshot carries no pre-build plan to compare against. Capacity feasibility of each build is unchecked until routings extend past the Huntsville flexi line (the standing data ask on the Schedule Board).
