Many classic problems only constrain end-of-period inventory. + +**Key interaction with the sell constraint:** If the model already has `sell[t] <= stock[t-1]` (grain bought this period cannot be sold this period), the model is bounded even without the after-purchase constraint.

The resulting intermediate has a **uniform composition** ā€” you cannot independently assign different raw materials to different products. + +### Why the standard blending LP is wrong here + +The standard blending LP uses variables `x[i][j]` (amount of raw material `i` in product `j`) and freely allocates each raw material to each product. When raw materials share a mixing step, the proportions of those raw materials must be **identical** in every product that receives the intermediate.

For each fixed `Ļƒ`, the problem is a standard LP (intermediate becomes a virtual raw material with known properties). Solve for a grid of `Ļƒ` values or use the structure to find the optimum analytically. + +3. **Scenario enumeration:** When only 2ā€“3 products exist, enumerate which products receive the intermediate (all-to-A, all-to-B, split).
