Portable intent card · signal-normalize
Sigmoid 1/(1+e^{−x}) back to probability space. Call when mapping model scores into probabilities without ML frameworks. Returns probability from score as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
