langchain holds an Evidaxis momentum score of 39.6 of 100 on methodology m2, snapshot 2026-08-08, measured within the Unassigned (AI-v1 census) cohort (n = 10). No axis is currently rising within the cohort, and no second (citation) axis is available, so it sits below the two-axis gate.

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.

Verdict

langchain is tracked. No axis is currently rising relative to its cohort, and it has no second (citation) axis available.

Path to Rising: needs development velocity to turn positive within its cohort; a second measurable axis to exist (no academic paper is currently tracked).
