vespa holds an Evidaxis momentum score of 45.0 of 100 on methodology m3, snapshot 2026-09-26, measured within the Unassigned (AI-v1 census) cohort (n = 5778). Axis coverage: 1 of 3 axes measurable. Gate: not computable — history 1 of 4 weekly observations

Derived signals

second-order reads, computed from the published series

Three signals ship when the commit series is statistically sufficient; the rest are held in a reserved state until the data supports them. A reserved signal shows its reason, never a fabricated number. How these are computed.
