OpenCode holds an Evidaxis momentum score of 57.2 of 100 on methodology m4, snapshot 2026-10-10, 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.

Measurement states
OpenCode is under weekly measurement. History: 15 weekly observations; minimum 4. Development velocity axis: measured. Citation source: not measured. Direct-dependents axis: measured. Gate: computed weekly across the cohort; no convergence event this week
This axis measures the trajectory of a system's own packages: declared in its own tree, published under that name, and not attributed by deps.dev to another repository. A package with no repository link is unverified and stays. The self-name exclusion list is fixed at the v2h.1 panel. Systems with no admitted package are not measured on this axis. Points that cannot be derived exactly are withheld, and the series restarts after a withheld point.
The earliest weekly points of each series were read from deps.dev's BigQuery history on 2026-07-21; later points are weekly captures. m4 does not replay those partitions: each point is the stored system total, one package's unique_direct, or a complete sketch union, and a point that is not exact is withheld. Each record reports how many of its points are reconstructed history.
