• no forecastAntimony: no free authoritative demand forecast - No free numeric antimony demand forecast exists: the International Antimony Association (i2a) publishes no market forecasts; USGS MCS 2026 has no forward numeric line; the SCRREEN3 2025 outlook is explicitly qualitative (it calls consumption estimates 'highly opaque'); the EC JRC ICT slice is ~0.4% of the ~100-142 kt/yr market (flame retardants + lead-acid are out of its scope).
• datedMaterial-flow analysis is historical - All 5 material-flow records date to 2000 or earlier (Yale STAF era). They describe the anthropogenic cycle of that period, not today's system.
• 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.
• datedExport-restriction inventory ends 2020 - The OECD industrial-raw-materials inventory (vendored snapshot) reports HS-line measures only through 2020; restrictions enacted since are not reflected in the measure table.
• narrowConsumption geography is single-economy (United States) - Reported consumption covers one economy only - the world usage split must be read from trade flows, not from a consumption table.

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.
