# Changelog

## Score

## Lenses

## Resolved (10)

- Coverage not included — suite not readable by the collector
- Dependency hygiene not measured — dependency manifest found but not parsed for hygiene
- Dormant codebase
- Duplicated block (10 lines × 2) (maple/src/main/java/com/twitter/maple/tap/MemorySinkTap.java)
- Largest orphaned file (scalding-base/src/main/scala/com/twitter/scalding/Execution.scala)
- Largest orphaned file (scalding-base/src/main/scala/com/twitter/scalding/typed/OptimizationRules.scala)
- Largest orphaned file (scalding-core/src/main/scala/com/twitter/scalding/mathematics/Matrix.scala)
- Workflow token permissions not restricted
- complexity unreadable for .rb, .scala — churn × complexity hotspots could not be measured
- dormant codebase — no living knowledge left to concentrate

## New (12)

- Context/problem and consequences are both absent; the body is a single decision statement with no framing (scalding-core/src/test/resources/com/twitter/scalding/test_filesystem/test_data/2013/03/2013-03.txt)
- Context/problem and consequences are both absent; the body is a single decision statement with no rationale (scalding-core/src/test/resources/com/twitter/scalding/test_filesystem/test_data/2013/07/2013-07.txt)
- Context/problem and consequences are both absent; the body is a single decision statement with no rationale (scalding-core/src/test/resources/com/twitter/scalding/test_filesystem/test_data/2013/08/2013-08.txt)
- Coverage not measured — test suite did not build
- Dimension evaluation failed
- Duplicated block (5 lines × 2) (scalding-parquet-scrooge/src/main/java/com/twitter/scalding/parquet/scrooge/ScroogeStructConverter.java)
- No artifact signing
- No context/problem and no consequences; the only visible element is a title '2013-04' with no decision (scalding-core/src/test/resources/com/twitter/scalding/test_filesystem/test_data/2013/04/2013-04.txt)
- No tests found
- early-stage repository — too little history to judge knowledge freshness
- single-commit history — no usable git history window to measure hotspots
- single-maintainer — knowledge-concentration (bus factor) risk
