Read progress at line level
Synthetic order O-11 has L1 ordered six, delivered four and open two; L2 ordered three and delivered all three. The preview exposes each line’s own history. It preserves the distinction between a completed line and an unfinished order.
| Input or inspection | Expected view | Business meaning |
|---|---|---|
| Inspect L1 | 6 ordered / 4 delivered / 2 open | L1 unfinished |
| Inspect L2 | 3 ordered / 3 delivered / 0 open | L2 complete |
| Open L1 history | D-1 delivers four against L1 | Evidence belongs to one line |
