No network calls; data baked into the repo.MEO basket weights & audit
Frozen reference for the 8 Oct 2025 basket. Caps and weights come from the bundled CSV/JSON; invariants are checked at render time. Use this as the readable counterpart to /demo and /equations.

World pool
$108,400,000,000,000
Aggregated fiat, metals, and crypto caps in USD.
MEO price
$108,400,000
Identity P_USD^{MEO} = κ · M_world.

Weights and USD market caps
Derived from the snapshot caps; should reconcile to Σ w_j ≈ 1.

| ETH | 0.4% | $433,600,000,000 | 0.4% δ=0.00e+0 |
δ shows |w_derived − w_reported|. In this offline build we derive weights from caps, so δ → 0 barring rounding.
Methodology (concise)
- Caps: MC_j^{USD} = P_j^{USD} · Q_j. Fiat uses M2 and FX; metals use above-ground stock and LBMA spot; crypto uses circulating supply and coin USD price.
- World pool: M_world = Σ_j MC_j^{USD}. Price: P_USD^{MEO} = κ · M_world, κ = 10^-6.
- Weights: w_j = MC_j^{USD} / M_world, with Σ w_j = 1. Invariants are asserted at runtime.
Integrity checks
|Σ w_j − 1| < 1e-9
Enforced after computing weights from caps.
|P_USD^{MEO} − κ Σ MC^{USD}| / P_USD^{MEO} < 1e-6
