• no dataNo commodity-decomposed scrap or end-of-life flows - No USGS MCS Fig13 scrap rows. EU WEEE / battery EOL flows (Phase 6.1.1) are country-keyed only - see country profiles.
• datedEnvironmental footprint is dated - Cradle-to-gate intensity rows carry a 2008 inventory vintage (Nuss & Eckelman-era LCA). Current-process footprints are not yet in scope.

The eight-stage lens, the observed-vs-estimated membrane, stage-honest supply, per-stage concentration, ownership resolution and the demand lens - the full method is illustrated live on copper, nickel and lithium.

This commodity's rows from strata's GCAM-CMM input bundle - graded supply curves (USGS reserves × benchmark cost model, 1975 USD/kg per GCAM convention), demand intensities, and the basis lineage that says exactly what each figure counts. These are inputs toGCAM: strata is the data; the model and its runs are PNNL's. Every file keeps its provenance header.
