# Changelog

## Score

- CAI 50 → 27 (-22.6)
- Rubric changed (rubric-2026.08.18 → rubric-2026.08.15) — scores are not directly comparable.

## Lenses

- Code Health 97 → 97 (+0.7)
- Architecture 100 → 96 (-4.4)
- Maturity 38 → 64 (+26.2)
- Readiness 50 → 23 (-26.5)
- Security 51 → 1 (-50.0)

## Resolved (13)

- Coverage not included — suite not readable by the collector
- Dependency hygiene not measured — dependency manifest found but not parsed for hygiene
- Dormant codebase
- FileTooLong: types/TypeConverter.scala (driver/src/main/scala/com/datastax/spark/connector/types/TypeConverter.scala)
- Largest orphaned file (connector/src/main/java/com/datastax/spark/connector/japi/CassandraJavaUtil.java)
- Largest orphaned file (connector/src/main/java/com/datastax/spark/connector/japi/RDDAndDStreamCommonJavaFunctions.java)
- Largest orphaned file (driver/src/main/scala/com/datastax/spark/connector/types/TypeConverter.scala)
- TooManyMethods: PriorityHashMap (connector/src/main/scala/com/datastax/spark/connector/util/PriorityHashMap.scala)
- TooManyMethods: ScalaGettableByIndexData (driver/src/main/scala/com/datastax/spark/connector/ScalaGettableByIndexData.scala)
- TooManyMethods: ScalaGettableData (driver/src/main/scala/com/datastax/spark/connector/ScalaGettableData.scala)
- TooManyMethods: TypeConverter (driver/src/main/scala/com/datastax/spark/connector/types/TypeConverter.scala)
- complexity unreadable for .java, .scala — churn × complexity hotspots could not be measured
- dormant codebase — no living knowledge left to concentrate
