# 2026-04-07 이슈 #12 Smoke 2회차 fix — Generator

- **이슈**: #12
- **롤**: Generator (Planner/Generator/Evaluator 사이클)
- **소요 시간**: ~50분
- **Context 사용량**: ~75k tokens

## 작업 요약

Smoke 1회차에서 발견된 4개 구조적 gap을 unit test 가능한 형태로 수정.

| Gap | 위치 | 수정 |
|-----|------|------|
| A | Player full-path resolver | `UiaPathParser` + `IUiaTreeNode`/`UiaPathResolver` 신규. `UiaPlayerHost.ResolveElement`가 FlaUI tree adapter로 segment chain descend |
| B | Recorder type step target inheritance | `DragCollapser`에 `lastFocusPath`/`lastMousePath` 추적, `FlushType()`이 typeRes 없을 때 fallback |
| C | SUT 외 창 필터 | `IWindowFilter` + `SutProcessWindowFilter` 도입, `LowLevelHook.Filter`가 mouse/key 모두 필터링. `Program.cs`에서 `WindowFromPoint`/`GetForegroundWindow` 와이어업 |
| D | UTF-8 BOM 없는 yaml 명시 | `ScenarioWriter.WriteToFile`이 `new UTF8Encoding(false)`로 저장 |

## 새 테스트 (10건)

Player.Tests:
- `UiaPathParser_ParsesMultiSegment_WithClassAndId`
- `UiaPathParser_ParsesNameAttribute`
