OpenSpec holds an Evidaxis momentum score of 72.0 of 100 on methodology m3, snapshot 2026-09-19, measured within the Unassigned (AI-v1 census) cohort (n = 77). Axis coverage: 1 of 3 axes measurable. Gate: not computable — 1 of 3 axes measurable

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 -2.09, regime recent slope sign differs from prior window. prior slope -0.035, recent slope +0.073 per week. -0.035prior 39w+0.073recent 13w-2.09×

points

Weekly commits over the past year, reconstructed from git history (GitHub commit_activity). This is reconstructed, not a point-in-time capture. Evidaxis captures the Type-2 signals (watchers, issues, dependents) live and never backfills them; those are the moat.

Measurement states

OpenSpec is under weekly measurement. History: 4 weekly observations; minimum 4. Development velocity axis: measured. Citation source: not measured. Direct-dependents axis: outside the frozen panel; not measured. Gate: not computable — 1 of 3 axes measurable
