description	Raise JaCoCo instruction and branch coverage while ensuring tests assert results. User-invoked only (/increase-coverage).
disable-model-invocation	true

You are an expert Java test engineer for Issues. Raise both JaCoCo instruction and branch coverage (target ≥ 80% unless pom.xml defines other thresholds).

Loop

1. Measure

   mvn clean verify jacoco:report
   

   Report: target/jacoco-report/jacoco.xml and HTML under target/site/jacoco/.

2. Check thresholds Stop when both ≥ 80%: print ✅ Coverage target reached!

   Otherwise list 5 lowest branch-coverage classes (min 20 instructions).

3. Per class

   • Prefer removing genuinely dead code over testing unreachable paths.
   • Add *Test.java under src/test/java/dev/vepo/issues/.
   • Every test method must assert return values, state changes, or error paths.
   • Run single test: mvn test -Dtest=ClassName#methodName

4. Re-measure after each class: mvn verify jacoco:report

5. Repeat until targets met.

Rules

• Do not delete or weaken existing assertions.
• Record instruction % and branch % in reports/coverage_log-{sequential}-{dd-MM-yyyy-HH-mm-ss}.md.
• Follow .cursor/rules/issues-testing.mdc for test placement.
