Letta holds an Evidaxis momentum score of 45.2 of 100 on methodology m5, snapshot 2026-11-07, measured within the Agent Frameworks cohort (n = 17). 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.

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.

Downstream packages depending on pypi/letta (deps.dev), captured point-in-time each snapshot. This daily series is unscored. The scored axis in m5 uses weekly partitions.

Measurement states

Letta is under weekly measurement. History: 19 weekly observations; minimum 4. Development velocity axis: measured. Citation axis: measured. Direct-dependents axis: no admitted own package; not measured. Gate: computed weekly across the cohort; no convergence event this week
