Metals framework

The plant climbs a fixed ladder. Each layer has one job. Consumption (the Ambient workspace, business intelligence, and regulatory exports) reads Titanium only, never raw layers.

Platinum sits after the ladder. It is a catalyst, not a higher medal. Models, features, and agents consume certified data there. They do not replace the plant.

Older medallion names, as aliases only: Bronze = Bronze. Silver = Aluminum. Gold = Titanium.

Organizations still on Stone or Copper engage Ivan Damnjanovic directly first. Once data is ready to import, Ambient Systems Limited delivers Bronze through Titanium on the ladder. Platinum is the after-ladder catalyst.
