Gymnasium holds an Evidaxis momentum score of 60.1 of 100 on methodology m3, snapshot 2026-09-26, measured within the Robotics & Embodied AI cohort (n = 16). Axis coverage: 2 of 3 axes measurable. Gate: not computable — reference measurement

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.

points
42

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.

Daily dependents count (unscored)

Downstream packages depending on pypi/gymnasium (deps.dev), captured point-in-time each snapshot. This daily series is unscored. The scored axis in m3 uses weekly partitions.

Measurement states

Gymnasium is under weekly measurement. History: 13 weekly observations; minimum 4. Development velocity axis: measured. Citation source: not measured. Direct-dependents axis: measured. Gate: not computable — reference measurement

This axis measures the frozen-panel trajectory of the package set selected and linkage-verified as of 2026-07-21. Systems outside that panel are not measured on this axis. Residual survivorship beyond the frozen universe is disclosed, not denied.

The earliest weekly points of each series were read from deps.dev's BigQuery history on 2026-07-21; later points are weekly captures. Each record reports how many of its points are reconstructed history.
