# Changelog

## Score

- CAI 55 → 48 (-6.7)
- Rubric changed (rubric-2026.08.18 → rubric-2026.08.15) — scores are not directly comparable.

## Lenses

- Code Health 96 → 94 (-1.8)
- Architecture 100 → 94 (-5.9)
- Maturity 37 → 50 (+12.7)
- Readiness 57 → 28 (-29.0)
- Security 71 → 71 (+0.0)

## Resolved (12)

- Coverage not included — suite not readable by the collector
- Dependency hygiene not measured — dependency manifest found but not parsed for hygiene
- Dormant codebase
- FileTooLong: pipeline/GenericPipeline.scala (training/src/main/scala/com/airbnb/aerosolve/training/pipeline/GenericPipeline.scala)
- FileTooLong: trainer/BinaryRegressionTrainer.scala (airlearner/airlearner-strategy/src/main/scala/com/airbnb/common/ml/strategy/trainer/BinaryRegressionTrainer.scala)
- FileTooLong: training/AdditiveModelTrainer.scala (training/src/main/scala/com/airbnb/aerosolve/training/AdditiveModelTrainer.scala)
- Largest orphaned file (airlearner/airlearner-strategy/src/main/scala/com/airbnb/common/ml/strategy/trainer/BinaryRegressionTrainer.scala)
- Largest orphaned file (training/src/main/scala/com/airbnb/aerosolve/training/AdditiveModelTrainer.scala)
- Largest orphaned file (training/src/main/scala/com/airbnb/aerosolve/training/pipeline/GenericPipeline.scala)
- TooManyMethods: PipelineUtil (airlearner/airlearner-utils/src/main/scala/com/airbnb/common/ml/util/PipelineUtil.scala)
- complexity unreadable for .java, .scala — churn × complexity hotspots could not be measured
- dormant codebase — no living knowledge left to concentrate
