What actually pays, what it costs, and where the stake comes from — after Alpenglow, VAT, and the disinflation debate. Full-stack breakeven of ~89K SOL today and ~78K post-Alpenglow at the $30,000 hosting case, ~77K at a measured $21,636 contract. Rebuilt in v11 after the model was found running on last year's inflation rate. Includes the commission asymmetry, and why the existing disinflation schedule does more to breakeven than SIMD-0411 would.
