Tabby holds an Evidaxis momentum score of 57.6 of 100 on methodology m3, snapshot 2026-09-26, measured within the Coding Agents cohort (n = 20). 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.

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

Tabby is under weekly measurement. History: 13 weekly observations; minimum 4. Development velocity axis: measured. Citation source: not measured. Direct-dependents axis: minimum of 14 clean points and 5 latest dependents not met. Gate: not computable — 1 of 3 axes measurable
