🟡 Cycle counts lost for class relationships
For a cyclic class edge outside edgesToRemove, cycleCount becomes zero. classEdgeCycleCounts only contains removal candidates, so package details misreport class-cycle participation.
Learn more
Count class-cycle membership for every nested relationship, not only removal candidates. Example: In a two-edge cycle, only one edge is selected for removal, leaving the other reported as zero. Recommended fix: Compute counts from all class cycles.

✅ Action performedFull review finished. |
Problem (line 876) .cycleCount(classEdgeCycleCounts.getOrDefault(classEdge, 0)) — classEdgeCycleCounts is populated by CycleRemovalComputer only for feedback-arc-set edges, so nested class edges behind a package edge (which are generally not FAS members) were always reported as members of zero class cycles, even when they participate in cycles. Fix (TDD red → green) - Red: PackageRelationshipClassEdgeCycleCountTest — a class graph with an Alpha ↔ Beta cycle plus a non-cycle Delta → Beta edge, both crossing a package edge; asserted cycleCount == 1 for the cycled edge. Failed with expected: <1> but was: <0>. - Green (JsonGenerator.java): - buildClassRelationshipsToBreakPackage now computes cycle membership for every class edge before constructing the DTOs (first pass builds a Map<edge, count>, second pass builds DTOs), via the new countClassCyclesContaining helper that iterates all classCycles values with containsEdge — the exact counting CycleRemovalComputer applies to FAS edges. Null-safe (no cycles → 0). - The classEdgeCycleCounts parameter was dropped (now redundant); method made package-private for direct testing. - Updated PackageRelationshipClassEdgeOrderTest to the new 3-arg direct call. Verification - Report module: 97 tests pass; full mvn clean install passes; spotless clean. - Regenerated jsonReport end-to-end: nested DTOs now carry computed counts. The zeros in this repo are truthful — the class graph's only class cycle is the same-package ReportWriter$SecureDirectoryOps cycle, and package cycles can exist without class cycles; the unit test proves non-cycle edges get 1+ when cycles actually contain them.

87-106: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winExercise a positive cycle edge that PageRankFAS does not select.
The test’s positive-count edge, Alpha → Beta, is selected by PageRankFAS for the two-edge cycle. Add Beta → Alpha to the helper input and assert its count is 1. That edge belongs to the same cycle but is not selected, so using only the feedback-arc-set count map would produce an incorrect nested DTO count that the current assertions miss.

42-53: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAdd a same-source pair to the ordering fixture.
The order test uses distinct sources, and the other tests that call the HTML or JSON builders do not assert target order. Add two edges with one source and differently ordered targets, then assert their target order in both outputs. This would catch a regression in the target tie-break without implying that the current implementation sorts incorrectly.

PackageRelationshipClassEdgeCycleCountTest - Added the Beta → Alpha edge (the cycle's reverse edge) to the nested set alongside Alpha → Beta and Delta → Beta. - New assertion: the Beta → Alpha DTO reports cycleCount == 1 (it's a member of the Alpha/Beta class cycle). - Existing assertions retained: Alpha → Beta == 1, Delta → Beta == 0. PackageRelationshipClassEdgeOrderTest - createClassGraph now adds a shared source pkgA.Multi with two edges inserted TargetZ first, then TargetB — so the targets' natural (sorted) order deliberately differs from their insertion order. - New JSON assertion: the Multi relationships list targets as [TargetB, TargetZ] (target-FQN order, not insertion order). - New HTML assertion: Multi → TargetB renders before Multi → TargetZ in the class-relationship cell, matching the JSON order. - Existing coverage retained: all 24 rotation comparisons (HTML cell + JSON order stable across set insertion orders), the full expected-cell reconstruction, and the HTML/JSON parity assertion — the shared-source pair now also flows through all of those.
