From the project's README
As published by sunrisesillneversee/sigrank-app in README.md. This repository publishes several servers, so only the opening is shown here.
Upsilon is the privacy-preserving measurement engine. SigRank is the public leaderboard and proof surface at signalaf.com. Run
npx sigrankto calculate Yield from four token counts. Never prompts or code.
Upsilon measures. SigRank proves. MO§ES™ governs. SignalAF is the brand.
SigRank evaluates the human using the AI, not the AI model itself. Most platforms reward volume. SigRank SignalAF rewards structure.
