Qualified service over time
The supply chain laboratory
A mine is a beginning.
Delivery is the test.
Follow a disruption through resources, separation, purchased alloys, magnet production and acceptance. Compare what the same budget can protect by the same deadline.
01 / Set up one experiment
Illustrative scenario · Python modelLoading the shared Python research model…
Results will identify the exact assumptions used.
02 / Follow the usable material
Six stages.
One delivery boundary.
Graph widths describe this scenario, not documented trade quantities.
Same budget · same horizon
Compare interventions.
03 / Keep the map and the model distinct
Source-backed contextA documented fragment.
An explicit gap.
Select an evidence path for context. Its places do not supply the model’s assumed capacities, yields, inventories or qualification times.

This is a scenario experiment. It cannot establish actual shipment provenance, supplier eligibility or a national investment optimum.
