Reading the report
Direction before conclusion.
This is a reproducible discovery snapshot, not a recommendation to adopt a dependency. Use movement to choose what deserves a deeper security, license, governance, and compatibility review.
Four explainable inputs
Recent work, contributor participation, community response, and release cadence shape the score.
A fixed comparison window
Every dated report uses the same 7-day signal and the nearest preceding stored UTC snapshot.
