strata's measured installed demand (deployment × intensity, per-row cited) scaled by the named GCAM scenario's activity index for the mapped model node - a dimensionless ratio, so the node's native unit cancels. The scenario and its runs are PNNL's; the installed base and intensities are strata's.

30 lanes GCAM 8.8 cannot scale - measured reasons
chromium · industry/steel/stainless - no per-grade steel axis (grep 'stainless': zero hits in extdata).
cobalt · industry/battery_cell/nmc - no battery-cell sector and no cathode-chemistry vocabulary ('NMC' absent).
cobalt · industry/hard_metals - no cemented-carbide sector (grep hits only EPA emissions-process accounting).
copper · buildings/floorspace - floorspace lives on GCAM's building-node structure (gcam.consumer resid/comm building nodeInput), not the sector/subsector/technology axis this map targets.
copper · electricity/grid_buildout - GCAM has no line-km/network-capacity buildout node; T&D exists only as an energy-margin pass-through (A26.*).
copper · electricity/solar/c-si - no per-cell-chemistry PV nodes in GCAM 8.8 (solar techs are PV/PV_storage/CSP/CSP_storage only).
copper · transport/ldv/phev - GCAM 8.8 has no PHEV node - 'PHEV'/'plug-in' absent from the whole input/ tree.
copper · transport/vehicle_production - GCAM models transport as SERVICE demand (trn_pass_road_LDV_4W output unit is billion pass-km, A54.sector.csv); vehicle manufacturing has no node.
dysprosium · transport/ldv/phev - GCAM 8.8 has no PHEV node - 'PHEV'/'plug-in' absent from the whole input/ tree.
gallium · electricity/solar/cigs - no per-cell-chemistry PV nodes (grep 'cigs': zero hits).
graphite · industry/battery_cell - no battery-cell MANUFACTURING sector (grep 'battery' hits only NREL ATB electricity-storage cost files).
graphite · industry/foundry - no foundry/castings sector (grep hits only ILO labour-statistics mappings).
graphite · industry/steel/refractories - no refractories node; refractory demand scales with 'iron and steel' sector output, but proxying on it is the consumer's modeling choice, not a node fact.
† withheld: GCAM 8.8's base-year output for this node is near zero, so its growth index is a model-base artifact (measured 335×, past the 25× ceiling this panel enforces), not a projection. Scaling a real installed base by it would manufacture absurd tonnages.
Installed demand is strata's measured base (deployment x intensity, per-row cited). Scenario paths scale it by the mapped GCAM node's physical-output growth index - a dimensionless ratio, so the node's native unit cancels. GCAM and its runs are PNNL's; strata is the data. Scenario outputs captured 2026-08-17 from bundle e1025cd3d2a2… (GCAM 8.8).
industry/battery_cell - no battery-cell MANUFACTURING sector (grep 'battery' hits only NREL ATB electricity-storage cost files).
industry/foundry - no foundry/castings sector (grep hits only ILO labour-statistics mappings).
industry/steel/refractories - no refractories node; refractory demand scales with 'iron and steel' sector output, but proxying on it is the consumer's modeling choice, not a node fact.

indium · electricity/solar/cigs - no per-cell-chemistry PV nodes (grep 'cigs': zero hits).
lithium · industry/battery_cell - no battery-cell MANUFACTURING sector (grep 'battery' hits only NREL ATB electricity-storage cost files).
manganese · industry/battery_cell/nmc - no battery-cell sector and no cathode-chemistry vocabulary ('NMC' absent).
neodymium · ict/consumer_electronics/portable_computers - 'resid computers' exists only in the GCAM-USA state add-on - a USA-only node in a global export would mislead.
neodymium · ict/consumer_electronics/smartphones - no node; GCAM-USA's device roster stops at 'Personal Computers' and is USA-only.
neodymium · transport/ldv/phev - GCAM 8.8 has no PHEV node - 'PHEV'/'plug-in' absent from the whole input/ tree.
nickel · industry/battery_cell/nmc - no battery-cell sector and no cathode-chemistry vocabulary ('NMC' absent).
nickel · industry/steel/stainless - no per-grade steel axis (grep 'stainless': zero hits in extdata).
niobium · industry/steel/hsla - no per-grade steel axis (grep 'HSLA': zero hits).
praseodymium · ict/consumer_electronics/portable_computers - 'resid computers' exists only in the GCAM-USA state add-on - a USA-only node in a global export would mislead.

tungsten · industry/steel/tool - no per-grade steel axis (grep 'tool steel': zero hits).
vanadium · industry/steel/hsla - no per-grade steel axis (grep 'HSLA': zero hits).
