Upsilon calculates the portable five-metric core from numeric telemetry. It does not require prompt text, response text, source code, or repository contents.
One architecture, four distinct roles
SignalAF is the umbrella brand. MO§ES™ supplies constitutional governance and methodology. Upsilon is the product and measurement engine. SigRank is the public leaderboard and proof surface.
Measurement boundary: Upsilon describes observable token-processing patterns. It does not, by itself, establish cognition, work quality, employee productivity, or business outcomes.
