faiss holds an Evidaxis momentum score of 11.0 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.

recency-weighted swing trailing 13-week vs prior 39-week log-slope ratio -1.65, regime recent slope sign differs from prior window. prior slope +0.042, recent slope -0.068 per week. +0.042prior 39w-0.068recent 13w-1.65×
