Pick a company to see where it actually produces — every country in its footprint, shaded by capacity share — overlaid with the countries whose register actions name it (severity ring + action count), plus violet arcs to the chokepoint countries its material inputs depend on. The map is a lens; the dossier and register are the source of record.
SK Hynix Inc. produces across 3 countries — 78% of mapped capacity sits in 🇰🇷 South Korea (HQ 🇰🇷 South Korea).
material exposures: silicon-wafers · photoresist-euv · rare-earth-magnets · helium
15 register actions name SK Hynix Inc., issued from 2 countries (top: 🇰🇷 South Korea ×8) — 2 of those also sit in its production footprint (regulator ∩ producer).

Its 3 scored input materials trace to 2 supplier countries — 1 refines >70% in a single country. Top input chokepoint: 🇨🇳 China (neodymium 85%, silicon 80%) — nearest ex-🇨🇳 neodymium producer: 🇲🇾 Malaysia ~8% — ~6-12mo to ramp (share-of-stage heuristic, not a sourced qualification time). (1 exposure without scored production data: photoresist-euv)Armed chokepoint: 🇨🇳 China has itself issued 17 register actions restricting the inputs it already dominates — neodymium (7), rare-earth-elements (6), rare-earths (5), silicon (2) — max severity 5/5.

Triple-overlap node: 🇺🇸 United States sits in all three layers at once — 7% of mapped capacity · 7 actions naming SK Hynix Inc. (max sev 5/5) · dominant world supplier of 1 scored input (helium 43%). One disruption there hits output, regulation and inputs together — the correlated tail a single-layer view misses. its US actions →Also multi-layer: 🇰🇷 South Korea (produces + regulates) · 🇨🇳 China (produces + supplies)
Named counterparties: this dossier names 2 firms with a source; 0 are in this corpus with a mapped footprint.1 other dossier names SK Hynix Inc. from the other side (supplier). 2 named firms could not be placed on the map — named in a primary source but not yet onboarded as a dossier, or onboarded without a production footprint. Named, not missing.
Reading the map: green shading = the company's production countries by capacity share, with dots at facility cities (dashed = approximate, country-level). Violet arcs = INPUT DEPENDENCIES — they run from the country that dominates world production/refining of a material the company consumes to the company's base; the % is that country's share of world supply at the named stage, NOT an import/export volume. Severity rings = countries whose register actions name the company.
