 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.

+
+DARPA's urgent January 2026 call for He-3-free cryocoolers demonstrates the substitution threat mechanism in action: defense establishment is actively accelerating terrestrial alternatives (ADR-based sub-kelvin cooling) specifically because He-3 supply is constrained. The 'urgent' designation indicates this is not speculative research but a strategic vulnerability requiring near-term solution. This extends the paradox beyond launch cost competition to include demand-side substitution driven by supply chain risk assessment.

 PRIMARY CONNECTION: Pattern 4 (He-3 demand temporal bound) — DARPA urgency is institutional evidence that the US defense market intends to exit He-3 dependence
 WHY ARCHIVED: US defense is a major He-3 demand segment; DARPA urgency is not a speculative indicator but an institutional signal of planned demand reduction
 EXTRACTION HINT: Frame as complementary to LEMON and KYb3F10 findings — three independent pressures (European research program, Chinese materials science, US defense commercialization) all pointing at He-3-free alternatives reaching qubit temperatures within Interlune's delivery window
