+- **작업**: Evaluator 채점 — Follow-up A (float epsilon 구성화) + Follow-up B (JSON-path mask scoping)
+- **Generator commit**: eeee3c2
+- **Verdict**: PASS
+- **관련 이슈**: normalizer follow-ups (see PLAN.md)
+- **소요 시간**: ~6분
+- **Context 사용량**: ~35k 토큰 (single session, no compaction)
+
+## 검증 결과
+
+- `dotnet build recordingtest.sln`: 0 warn / 0 err
+- `dotnet test recordingtest.sln --no-build`: 77 passed / 0 failed (Player 16, Recorder 17, Normalizer 16, EgPlugin 5, DiffReporter 5, Runner 6, EngineBridge.Integration 6, EngineBridge 6)
+- Normalizer.Tests 10 → 16 확인 (6 신규)
+- `VolatileSettingFieldNames` 잔존 없음 (grep src/ empty)
+- Regression trap `SameNameInUnrelatedSubtree_NotMasked` load-bearing 확인 — 구버전 name-based 매칭이면 nested bool GetValue에서 throw
