OpenCode holds an Evidaxis momentum score of 52.0 of 100 on methodology m3, snapshot 2026-09-26, measured within the Coding Agents cohort (n = 20). Axis coverage: 2 of 3 axes measurable. Gate: computed weekly across the cohort; no convergence event this week

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.

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.
