Plan from the material on the rack, including reusable leftovers.

Two pieces of the same material can have different dimensions, locations, or availability. Item-level identity lets the planner select a usable source and lets the work order point back to it.

• —Full stock and remnant identity
• —Material and dimensional attributes
• —Availability in the planning flow
• —Source reference in accepted results

A leftover becomes useful when its usable dimensions and compatibility are known. Eligible remnants can enter candidate selection instead of disappearing into an unstructured scrap pile.

• —Remnant-aware candidate selection
• —Usable geometry after prior cuts
• —Compatibility with requested parts
• —Expected new remnants in the result

Source assignments, consumption, waste, and expected remnants belong to the same plan. That continuity supports execution and later inventory decisions without reinterpreting an optimizer output.

• —Source-to-placement traceability
• —Expected consumption
• —Waste visibility
• —Reusable leftover visibility
