Why a field shows "—": A dash means the value is not published by the source registry for that package. Quanteta never fills in a guessed value — a missing field stays blank.

Derived indices (computation method published)

Quanteta-computed from the registry values below. This is a derived index, not a measured registry metric. See the formula on the Data & Sources page.

Q-Vitality Quanteta 74.3 / 100 Maintenance activity index (release cadence + download level).
Q-Trust Quanteta 1.4 / 100 Adoption / stability index (community size + download stability + age).
Q-Risk Quanteta 8.5 / 100 Dependency-surface index. Higher = more risk factors detected.
