headroom holds an Evidaxis momentum score of 44.1 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.

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
headroom 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
