Stratum Verification Notes

Methodology: Workshop telemetry and physical constants compiled from official Unreal Engine string tables (GCMC-Windows.pak / Game.locres). Metal ores (such as Malachite and Pyrite) are broken down directly with hammers to harvest base metals for workbench upgrades rather than faceted for fine jewellery.
