+# Evaluation — smoke2 gap fix (issue #12)
+
+- Commit graded: `8784fec`
+- Evaluator: independent session (Opus 4.6 [1m])
+- Date: 2026-04-07
+- Note: Issue #12 used a free-form issue body instead of a Sprint Contract
+  (`docs/contracts/smoke2-gap-fix.md` does not exist). Acceptable per
+  CLAUDE.md §0.1 for follow-up bug fixes, but recorded here.
+
+## Verdict: **PASS**
+
+## Verdict table
+
+| Item | Required | Observed | Status |
+|---|---|---|---|
+| Build | 0 warn / 0 err (TWAE) | Clean, 0/0 | pass |
+| Tests total | 71 pass / 0 fail / 0 skip | 71 pass / 0 fail / 0 skip (16+10+17+5+5+6+6+6) | pass |
+| Gap A — full path resolver | UiaPathParser splits `/`, parses `(Class, AutomationId?, Name?)`; `IUiaTreeNode` adapter; descend chain id→name→class; bounded fallback; UiaPlayerHost wired; null on miss | All present. `UiaPathParser.cs` quote-aware split, attribute parser. `IUiaPathResolver.cs` defines `IUiaTreeNode` + `UiaPathResolver` with `MatchRoot` + `FindChild` + `DescendantsBounded(maxDepth:4)` documented fallback. `Matches` priority AutomationId > Name > ClassName. `UiaPlayerHost.ResolveElement` uses `UiaPathResolver.Resolve(new FlaUiTreeNode(window), uiaPath)` via `Retry.WhileNull`, returns null on miss (engine handles throw). Old `ExtractAutomationId` shortcut removed. | pass |
+| Gap B — type target inheritance | `_lastFocusPath` / `_lastMousePath` state; FlushType fallback chain (typeRes → focus → mouse) | `DragCollapser` adds `lastFocusPath` + `lastMousePath` locals (line 46-47); `FlushType` fallback `typeRes ?? lastFocusPath ?? lastMousePath` (line 72); focus_change updates `lastFocusPath` (line 332); mouse_down_l/r updates `lastMousePath` from downRes (line 128, 188). | pass |
+| Gap C — window filter | `ShouldKeep`; mouse uses `WindowFromPoint`; key uses `GetForegroundWindow`; wired to SUT pid in Program | `WindowFilter.cs`: `IWindowFilter`, `PassThroughWindowFilter`, `SutProcessWindowFilter` with two pluggable lookups. Mouse path → `processFromPoint`, key path → `processFromForeground`, focus_change always kept, pid==0 permissive. `Program.cs` lines 87-107 wires `SutProcessWindowFilter` to `app.ProcessId` using `WindowFromPoint`+`GetWindowThreadProcessId` and `GetForegroundWindow`. `LowLevelHook` exposes mutable `Filter` and applies it in both Keyboard/Mouse procs. | pass |
+| Gap D — UTF-8 BOM-less | Explicit `UTF8Encoding(false)`; round-trip test with Korean strings + no BOM | `ScenarioWriter.WriteToFile` line 43-44: `new UTF8Encoding(encoderShouldEmitUTF8Identifier: false)`. Round-trip test `ScenarioWriter_RoundTrip_PreservesKorean` asserts byte[0..2] != EF BB BF and Korean Name/Description/Path round-trip. | pass |
+| Thread.Sleep in PlayerEngine | 0 | 0 (grep) | pass |
+| EG-BIM Modeler writes | none | none | pass |
+
+## Regression-trap analysis
+
+| New test | Would have failed pre-fix? | Why |
+|---|---|---|
+| `UiaPathParser_ParsesMultiSegment_WithClassAndId` | yes — `UiaPathParser` did not exist | Compile-trap |
+| `UiaPathParser_ParsesNameAttribute` | yes | Compile-trap |
+| `UiaPathResolver_Descend_FindsNestedElement` | yes | Compile-trap; also exercises chain descent |
+| `UiaPathResolver_LastSegmentWithoutId_UsesClassName` | yes | Validates ClassName fallback in `Matches` |
+| `UiaPathResolver_NotFound_ReturnsNull` | yes | Validates null-not-throw contract |
+| `SmokeRegression_BoxV4CleanLike_ParsesAndResolves` | yes — explicitly proves the resolver no longer collapses to "first descendant" (Assert.NotSame) | Direct guard against the smoke 1차 bug |
+| `DragCollapser_TypeAfterFocusChange_InheritsTarget` | yes — pre-fix `FlushType` only used `typeRes`; with all-null resolver result, `Target` would be null. Test asserts `Target.UiaPath == focusPath`. | Direct guard for Gap B |
+| `DragCollapser_TypeAfterMouseDown_FallbackToMouseTarget` | yes — same reason; asserts mouse path inheritance | Direct guard |
+| `WindowFilter_ExternalCoord_DropsEvent` | yes — `SutProcessWindowFilter` did not exist | Compile-trap; also asserts drop semantics |
+| `WindowFilter_SutCoord_KeepsEvent` | yes | Compile-trap; asserts keep + permissive pid=0 |
+| `ScenarioWriter_RoundTrip_PreservesKorean` | yes — pre-fix relied on default overload; the explicit byte-level `EF BB BF` assertion + Korean round-trip would only deterministically pass with the explicit encoder | Direct guard for Gap D |
+
+All new tests are load-bearing.
+
+## Notes
+
+- `docs/guides/smoke-test.md` Gap D tip section confirmed (commit diff shows +18 lines).
+- No partial hacks observed; all four gaps are real code-level fixes with
+  unit coverage and reasonable abstractions (pluggable lookups for the
+  filter, pure adapter for the path resolver).
+- Recommend Generator update PROGRESS.md to mark issue #12 done.

+# 2026-04-07 이슈 #12 — Smoke 2차 gap fix 오케스트레이션
+
+- **이슈**: #12 (smoke 1회차 후속 4-gap fix)
+- **소요 시간**: ~15분 (Generator ~6분 + Evaluator ~2분 + orchestrator 마무리)
+- **Context 사용량**: ~400k tokens (orchestrator 누적)
+
+## 사이클
+
+1. Smoke 1회차 발견 4-gap 이슈화 (#12 open)
+2. Generator 백그라운드 → commit `8784fec` (60 → 71 tests)
+3. Evaluator 백그라운드 → **pass** (4/4 gap pass + regression trap 검증)
+4. PROGRESS 갱신, 이슈 close, commit + push
+
+## 수정 요약
+
+- **Gap A**: `UiaPathParser` + `UiaPathResolver` + `IUiaTreeNode` 새 추상화. 기존 last-AutomationId 휴리스틱 제거. ancestor chain 따라 descend하며 id→name→class 우선.
+- **Gap B**: `DragCollapser`에 `lastFocusPath`/`lastMousePath` 추가. `FlushType` fallback chain 적용.
+- **Gap C**: `SutProcessWindowFilter` + P/Invoke `WindowFromPoint`/`GetForegroundWindow`. `Program.cs`가 attached pid로 wire.
+- **Gap D**: `ScenarioWriter`가 UTF-8 BOM-less 명시. 한글 round-trip 테스트 + BOM 부재 assertion.
+
+## 비용
+
+Generator ~92k + Evaluator ~58k + Orchestrator ~15k = **~165k**
+
+## 다음 단계
+
+**Smoke 2회차** — 실제 EG-BIM Modeler에서 짧은 Box 시나리오 재검증. 기대:
+- click이 정확한 element 잡음
+- type "BOX"/"10" 실제로 입력됨
+- SUT 외 이벤트 필터됨
+- Box가 화면에 실제로 그려짐
