 Interlune's milestone-gated financing structure suggests investors are managing the 'launch cost competition' risk by deferring capital deployment until technology proves out. The $23M raised vs. $500M+ contracts ratio shows investors won't fund full-scale infrastructure until extraction is demonstrated, precisely because falling launch costs create uncertainty about whether lunar He-3 can compete with terrestrial alternatives or Earth-launched supplies.

+ADR systems using frustrated magnets (KYb3F10) achieved 27.2 mK in July 2025, approaching superconducting qubit temperatures and demonstrating that He-3 substitution technology is advancing faster than previously assumed. The gap between research ADR (27.2 mK) and qubit requirements (10-15 mK) is now only ~2x, compared to commercial ADR at 100-300 mK (4-10x gap). This accelerates the substitution timeline for He-3 demand in quantum computing, the primary terrestrial application driving cislunar He-3 extraction economics.

 PRIMARY CONNECTION: Pattern 4 (He-3 demand temporal bound) — this is the key technical evidence on the He-3 substitution timeline
 WHY ARCHIVED: Most important technical finding of the session — resolves the "does ADR plateau at 100-500 mK?" question with evidence that research ADR is now approaching superconducting qubit temperatures
 EXTRACTION HINT: Focus on the gap between 27.2 mK achieved and 10-15 mK needed — this gap (~2x) is much smaller than the commercial ADR gap (100-300 mK, or 4-10x). Extractor should calibrate substitution timeline: research at 27 mK now, commercial products likely 5-8 years from here.
