SigRank — operator-first token efficiency leaderboard (signalaf.com)

Hey YeonGyu — noticed you're @sionic-ai and deep in the AI hacking space. I built SigRank (signalaf.com), the first leaderboard that ranks the operator, not the model. Not volume — token cascade efficiency: Yield = (cache_read * output) / input^2.

The interesting finding: power users often score worse on efficiency than casual users. 22x cache leverage with 0.08 output velocity doesn't pay. Yield demands both.

`npx sigrank` in your terminal — reads your local logs, shows your full cascade + projected rank. Would be genuinely curious where you land.

Happy to close this issue regardless.
