When does lunar surface manufacturing become cheaper than Earth launch for orbital infrastructure?

Full leaf pass complete on q4-gear-ratio. 14 claims (10 high-conf, 4 medium). Codex tag-team caught real overclaims in calc and orphan numerical claims in write — both corrected per protocol. Leaf answer: ~35x threshold model-contingent, attainable per published TEAs (tent sublimation 10x headroom), LEO requires non-chemical architecture, TAI-grade automation compresses headroom further. Two flags for Avi: orphan claims minor cleanup pending, ξ time-evolution model needs rigorous treatment.

First-principles φ-threshold derivation. Tsiolkovsky math + Γ_X physics solid (Codex confirmed). Cost-parameter sweep collapses to ∞ thresholds — flagged in audit, deferred to reconcile. 5 claims added to claims.yaml.

Metzger 2023 fetched + full extract written. Pass-01 research log captures sources, key insights, public figures for review. No claims yet (per protocol).

Tree v1 created with 8 leaves; key addition q4-gear-ratio (Metzger 35x threshold). 6 public figures identified for future source reviews. 9 seed sources catalogued.
