mattrobball / mathlib4_fork
The math library of Lean 4
mattrobball/mathlib4_fork tiene un índice de salud de 37 sobre 100, lo que lo sitúa en la banda En riesgo. Su puntuación más alta es Sustainability & Governance (75/100) y la más baja, Community & Adoption (12/100). Se actualizó por última vez hace 129 días. 12 personas concentran la mayor parte del trabajo reciente.
37
global / 100Índice de salud del software
Las métricas se agrupan en categorías ponderadas sobre una escala de 1 a 100. El resultado global parte de su media; cuando la evidencia pública activa la Política de Jurisdicciones de Alto Riesgo, la calificación se ajusta y recibe el límite 49 (En riesgo). Preparación para IA queda fuera.
37
Excelente85-100Ejemplar; cumple prácticamente todos los criterios evaluados
Bueno70-84Saludable; carencias menores
Moderado50-69Aceptable con carencias notables; se recomienda revisión
En riesgo30-49Debilidades significativas; su adopción exige cautela
Crítico1-29Problemas graves (proyecto abandonado, un solo mantenedor, sin higiene)
Perfil de puntuación
Cada eje es una categoría. La forma importa más que la media: un proyecto sano llena toda la figura, mientras que un perfil de picos y cráteres indica que la fortaleza en una dimensión enmascara el riesgo en otra.
Abandonment Policy applies a 85% multiplier to weighted overall health.

Alerta de abandono
Ha llegado trabajo y nadie se ha ocupado de él
ningún commit humano en 411 díascommits automatizados excluidospublicaciones detenidasOpenSSF Scorecard lo reporta sin mantenimiento
El silencio por sí solo nunca es el hallazgo: una biblioteca pequeña y terminada puede no necesitar commits durante años. Esta alerta exige ambas cosas: mucho tiempo sin un commit humano y obligaciones que el proyecto visiblemente no atiende. Los commits automatizados no cuentan como mantenimiento.

OpenSSF Scorecard 3.8 / 10
3.8agregado
Evaluación de seguridad independiente y agnóstica en cuanto a herramientas, procedente del proyecto de código abierto OpenSSF Scorecard. Cada comprobación premia una práctica de seguridad, no la herramienta de un proveedor concreto. Las comprobaciones que Scorecard no pudo determinar se marcan como n/d y se excluyen de la puntuación de seguridad (nunca se cuentan como cero).
