**Question:** How fast is the reusability gap closing, and does this change the single-player dependency diagnosis?
**Key finding:** The reusability gap is closing much faster than predicted — from multiple directions simultaneously. Blue Origin landed a booster on its 2nd orbital attempt (Nov 2025) and is reflying it by Feb 2026. China demonstrated controlled first-stage sea landing (Feb 2026) and launches a reusable variant in April 2026. The KB claim of "5-8 years" for China is already outdated by 3-6 years. BUT: while the reusability gap closes, the capability gap widens — Starship V3 at 100t to LEO is in a different class than anything competitors are building. The nature of single-player dependency is shifting from "only SpaceX can land boosters" to "only SpaceX can deliver Starship-class payload mass."
**Pattern update:** First session — establishing baseline patterns:
- Pattern 1: Reusability convergence across 3 independent approaches (tower catch / propulsive ship landing / cable-net ship catch). This suggests reusability is now a solved engineering problem, not a competitive moat.
- Pattern 2: Institutional timelines slipping while commercial capabilities accelerate (Artemis III descoped, commercial stations delayed, but Varda at 5 missions, Blue Origin reflying boosters).
- Pattern 3: Governance gap confirmed across every dimension — debris removal at 5-8% of required rate, Artemis Accords at 61 nations but no enforcement, ISRU blocked by resource knowledge gaps.
**Confidence shift:** Belief #6 (single-player dependency) weakened — the dependency is real but narrower than stated. Belief #4 (microgravity manufacturing) strengthened — Varda executing faster than KB describes. Belief #3 (30-year attractor) unchanged in direction but lunar ISRU timeline component is weaker.
