feat: camera-restore + LauncherUI UX 개선 + player fallback 강화 (#15)

camera-restore:
- IEngineStateProvider.SetCamera 반사 쓰기 (HmegDirectStateProvider)
- POST /camera/restore (BridgeHttpServer, StateRouter)
- Recorder --sidecar-url + camera_snapshot 캡처
- UiaPlayerHost.TryRestoreCamera, PlayerEngine 재생 전 복원
- 149 tests

LauncherUI (#15):
- Sidecar URL 체크박스 + 입력란 (녹화/재생 모두 연동)
- 재생 속도 슬라이더 (0.25x~4.0x, 기본 1.0x)
- 빌드 타임스탬프 타이틀바 표시
- 녹화 완료 후 RecordNameBox 초기화
- UiAnalysisWindow 추가

+- `docs/contracts/<이름>.md` — Sprint Contract
+- Generator의 산출물 (코드, 시나리오, 베이스라인, 카탈로그 등)
+- 계약에 명시된 픽스처 또는 오라클
+
+## 방법
+1. 계약을 읽는다. 없으면 거부하고 호출자에게 먼저 `planner`를 실행하라고 알린다.
+2. 각 DoD 항목에 대해:
+   - 명시된 검증을 실행한다 (스크립트, diff, 검사).
+   - **근거**를 기록한다 (명령 출력, 파일 경로, diff 조각).
+   - 점수 매기기: `pass` / `fail` / `partial` / `untestable`.
+3. 전체 판정 계산: 모든 항목이 pass일 때만 pass.
+4. 타임스탬프와 함께 `docs/contracts/<이름>.evaluation.md`에 보고서 작성.
+5. 실패 항목이 있으면 PROGRESS.md를 done으로 표시하지 **않는다**. 보고서를 호출자에게 반환한다.
+
+## 규칙
+- 자화자찬 금지, 관대한 해석 금지. 애매한 결과는 `partial` 또는 `untestable`로 처리한다.
+- 채점 중인 산출물을 수정하지 않는다. 읽기/실행 명령만 사용한다.
+- 사용 가능한 도구로 DoD 항목을 테스트할 수 없으면 `untestable`로 표시하고 이유를 설명한다 — 가짜 pass 금지.
+- 보고서는 간결하게: DoD 항목마다 근거 링크가 포함된 한 줄 bullet.

-이 파일은 Claude Code가 본 저장소에서 작업할 때 항상 읽는 프로젝트 운영 지침이다.
+## 세션 시작 (필수)
 
-## 0. 세션 시작 시 필독 (모든 에이전트)
+1. [PROGRESS.md](PROGRESS.md) 읽기 — 완료/진행 중/차단 현황
+2. [PLAN.md](PLAN.md) 읽기 — 다음 할 일 우선순위 큐
+3. 작업 선택 → PROGRESS.md "In progress" 표시
+4. 완료 시: PROGRESS.md Done 이동 + PLAN.md 갱신 + `docs/history/YYYY-MM-DD_{작업명}.md` 작성 (소요시간·Context 사용량 필수, 누락 시 커밋 차단)
 
-여러 에이전트가 작업을 분담하므로, **세션을 시작하는 모든 에이전트는 가장 먼저 다음 두 파일을 읽는다:**
+## 작업 사이클 — Planner / Generator / Evaluator
 
-1. [PROGRESS.md](PROGRESS.md) — 지금까지 *무엇이 끝났는가*. 모듈별 진행 상태, 최근 완료 작업, 현재 차단 이슈.
-2. [PLAN.md](PLAN.md) — 앞으로 *무엇을 해야 하는가*. 모듈별 To-Do, 담당 에이전트, 우선순위, 의존 관계.
+비자명한 작업은 반드시 3단계:
 
-읽고 나서 자신이 맡을 작업을 PLAN.md에서 고르고, 시작 시 PROGRESS.md에 "in progress"로 표시한다. 작업이 끝나면:
-- PROGRESS.md 의 해당 항목을 "done"으로 옮기고 날짜·결과·산출물 경로 기록
-- PLAN.md 의 완료 항목 제거 또는 다음 단계로 갱신
-- `docs/history/YYYY-MM-DD_{작업명}.md` 히스토리 파일 작성 (소요 시간·Context 사용량 필수)
+1. `/contract <name>` → `docs/contracts/<name>.md` (Goal, DoD, Interfaces, Risks)
+2. Generator — DoD만 충족, 스코프 이탈 금지
+3. `/evaluate <name>` → `docs/contracts/<name>.evaluation.md` — **pass여야만** PROGRESS.md Done 이동
 
-**원칙:** PROGRESS.md와 PLAN.md는 *에이전트 간 공유 메모리*다. 자기 머릿속에만 두지 말고 반드시 파일에 반영해야 다음 에이전트가 이어받을 수 있다. 충돌 시 최신 커밋 기준으로 머지하고, 모호하면 사용자에게 질문한다.
+**Generator와 Evaluator는 같은 세션이 겸하지 않는다.**
 
-## 0.1 작업 사이클 — Planner → Generator → Evaluator
+컨텍스트가 차면 요약 말고 **파일에 상태를 쏟고 새 세션으로 리셋**.
 
-Anthropic의 "Harness Design for Long-Running Agent Applications" 설계 원칙을 채택한다.
-핵심: **생성자와 평가자를 같은 에이전트가 겸하지 않는다**. 자기 작업을 과대평가하는 편향을 피하기 위해서다.
+## 프로젝트
 
-모든 비자명한(non-trivial) 모듈/기능 작업은 다음 3단계를 거친다:
+**recordingtest** — WPF 3D 편집기(EG-BIM Modeler, HmEG 엔진, MEF 플러그인)에 대한 입력 회귀 테스트 자동화 도구.
 
-1. **Planner (`/contract <name>`)** — 사용자의 요청을 Sprint Contract로 변환.
-   - 산출물: `docs/contracts/<name>.md` (Goal, **Definition of Done**, Interfaces, Out of scope, Evaluation plan, Risks)
-   - DoD 항목은 **객관적으로 검증 가능**해야 한다. "잘 동작한다"는 금지.
-   - `PLAN.md`에 해당 항목 추가.
+전략: 입력 레코딩 → 리플레이 → 결과물을 `*.approved.*` 베이스라인과 diff (ApprovalTests 패턴).
 
-2. **Generator** — Sprint Contract를 계약으로 삼고 실제 구현. 일반 세션 또는 전용 구현 에이전트가 수행.
-   - 계약을 읽고 DoD 항목만 충족시키는 데 집중.
-   - 스코프 이탈 금지. 범위 변경이 필요하면 planner를 다시 호출.
+## 코드 계층 (의무)
 
-3. **Evaluator (`/evaluate <name>`)** — 독립된 `evaluator` 서브에이전트가 계약 기준으로 채점.
-   - 산출물: `docs/contracts/<name>.evaluation.md` (verdict + evidence table)
-   - **fail**이면 PROGRESS.md에 done으로 옮기지 않는다. Generator가 재작업.
-   - **pass**여야만 호출자가 PROGRESS.md를 갱신한다.
-
-### 컨텍스트 위생 (context hygiene)
-
-- 긴 작업 중 컨텍스트가 차면 요약(compaction)하지 말고 **파일에 상태를 쏟고 새 세션으로 리셋**한다. PROGRESS.md/PLAN.md/Sprint Contract가 그 인계 창구다.
-- Stop hook이 핸드오프 누락을 경고한다. 무시하지 말 것.
-- 모델/하네스가 진화하므로 `.claude/` 비계는 주기적으로 감사·축소한다 (PLAN.md에 "scaffolding review" 상시 항목 유지).
-
-## 1. 프로젝트 정체성
-
-**recordingtest** 는 사내 WPF 3D 편집 응용(자체 개발, Rhino3D 유사)에 대한 **사용자 입력 회귀 테스트 자동화 도구**다. 도구 자체이지 SUT가 아니다.
-
-### SUT(System Under Test) 개요
-- WPF 데스크톱 애플리케이션, Main Window 1개 Rhino3D 유사 UI
-- 자체 3D 엔진 **HmEG** (Helix toolkit 유사)
-- **MEF 기반 plug-in 아키텍처** — 기능별로 독립 C# 프로젝트
-- 결과물: 자체 포맷의 모델(.hmeg)/프로젝트 저장 파일
-
-## 2. 핵심 전략 — Golden-file 회귀
-
-> 수동 테스트 입력을 레코딩 → 리플레이 → 결과 저장 파일을 베이스라인과 diff.
-
-ApprovalTests 패턴과 동형. SUT 코드 변경 협조를 최소화하기 위한 의도적 선택.
+3개 계층, 단방향 의존:
 
 ```
-[수동 테스트] → 입력 레코드 + 결과 파일 A (baseline)
-[회귀 시점]   → 입력 리플레이 → 결과 파일 B → normalize → diff(A, B)
+App-specific (Sut/EgBim/)  →  HmEG-aware (Hmeg/)  →  Generic (src/ 직속)
 ```
 
-**우선순위:**
-- 1순위: recorder, player, 정규화(normalizer), diff-reporter
-- 2순위: engine-bridge (엔진 상태 sidecar JSON 덤프)
-- 후순위: viewport-verifier (픽셀/이미지 비교) — golden-file로 못 잡는 케이스 보강용
+| 계층 | 참조 가능 | 위치 | 네임스페이스 |
+|---|---|---|---|
+| Generic | .NET BCL, FlaUI, Win32, YAML만 | `src/` | `Recordingtest.*` |
+| HmEG-aware | Generic + HmEG.dll만 | `src/Hmeg/` | `Recordingtest.Hmeg.*` |
+| App-specific | Generic + HmEG-aware + 앱 어셈블리 | `src/Sut/<App>/` | `Recordingtest.Sut.<App>.*` |
 
-## 3. 아키텍처 구성요소(예정)
+역참조 금지. `Recordingtest.Architecture.Tests` 가 의존 그래프를 자동 검증한다.
 
-| 모듈 | 책임 |
-|------|------|
-| `sut-prober` | 대상 앱 실행, UIA 트리·MEF plugin 목록 덤프 |
-| `recorder` | 입력 캡처(키/마우스/포커스) + element path + offset 동시 저장 |
-| `player` | 시나리오 재생, 비동기 작업 동기화 |
-| `normalizer` | 저장 파일 정규화(타임스탬프/GUID/경로/부동소수점/순서) |
-| `diff-reporter` | baseline vs received diff, 갈라진 지점 시각화 |
-| `engine-bridge` | HmEG 내부 상태(카메라/선택/씬그래프) sidecar JSON 노출 |
-| `test-runner` | 시나리오 묶음 실행, 리포트 |
-| `viewport-verifier` | (후순위) 3D 스크린샷 SSIM 비교 |
+계층 이동·신규 SUT 추가 시 `/contract` 필수. 폴더 레이아웃: [docs/architecture.md](docs/architecture.md)
 
-각 모듈은 독립 PoC → 통합 순서로 진행한다.
+## 설계 규칙
 
-## 4. 기술 스택 가이드
+- **고정 sleep 금지** — UIA 이벤트/property change 대기
+- **좌표만 저장 금지** — UIA element path + 상대 offset 필수 기록
+- **새 필드 추가 시 정규화 규칙 동시 등록**

-- **언어**: C# / .NET (SUT와 동일 생태계, in-process probe 가능)
-- **UI 자동화**: **FlaUI** 1순위 (UIA 기반, .NET 네이티브). WinAppDriver/Appium은 fallback.
-- **저수준 입력**: Win32 SetWindowsHookEx (low-level mouse/keyboard) — element 매칭과 hybrid
-- **시나리오 포맷**: JSON 또는 YAML (git diff 친화적). 바이너리 금지.
-- **베이스라인 파일**: `*.approved.{ext}` / `*.received.{ext}` 명명 규칙
-- **이미지/큰 베이스라인**: Git LFS

-## 5. 반드시 지킬 설계 원칙
-
-1. **결정성(Determinism) 우선** — 비결정적 요소(시각·랜덤·경로·GUID·부동소수점·컬렉션 순서)는 정규화 파이프라인을 통과해야 한다. 새 필드 추가 시 정규화 규칙 동시 등록.
-2. **Element-aware 입력 캡처** — 좌표만 저장 금지. 항상 UIA element path + 상대 offset을 같이 기록해 해상도/DPI/창크기 변화에 견디게 한다.
-3. **타이밍 동기화** — 고정 sleep 금지. UIA 이벤트, property 변경, plugin 로드 완료 신호를 대기한다.
-4. **Dispatcher marshaling** — SUT 내부 probe/hook 코드는 반드시 WPF UI thread 위에서 동작.
-5. **체크포인트** — 한 시나리오 안에서 여러 번 저장→비교 가능해야 한다(이분 탐색용).
-6. **실패 아티팩트 풀세트** — 실패 시 스크린샷, UIA 트리 덤프, 엔진 상태 sidecar, 입력 로그, diff를 한 폴더에 동시 저장.
-7. **SUT 침습 최소화** — AutomationPeer/probe 부착이 필요하면 별도 어셈블리로 격리하고 SUT 팀과 합의 후 진행.
-8. **민감정보 마스킹** — 레코딩에 비밀번호/토큰 포함 금지.
-
-## 6. 환경 제약
-
-- **세션 0 불가**: WPF는 대화형 데스크톱 세션 필요 → CI에서 헤드리스 불가, RDP/대화형 agent 필요
-- **DPI/멀티모니터 정규화**: 테스트 머신은 고정 DPI 권장
-- **GPU 의존**: 3D 렌더 결과는 드라이버 영향 → 픽셀 비교는 항상 톨러런스 + 마스킹
-
-## 7. 작업 흐름 규칙
-
-### 히스토리 기록 (필수)
-모든 작업 완료 시 `docs/history/YYYY-MM-DD_{작업명}.md` 작성. 필수 항목:
-- **소요 시간**
-- **Context 사용량**
-- 관련 이슈 (#N)

-### Claude 작업 원칙
-- **세션 시작 시 PROGRESS.md / PLAN.md 먼저 읽기** (§0 참조)
-- 코드 변경 전 관련 파일 read 필수
-- 테스트 자동화 도구 자체의 회귀를 위해 본 저장소 코드도 단위 테스트 보유 권장

+## 3계층 아키텍처
+
+본 도구는 **EG-BIM Modeler 외 다양한 WPF 응용**을 대상으로 하고, 사용자 WPF 응용군 대다수가 자체 3D 엔진 **HmEG**를 공유한다. 따라서 코드는 엄격히 3계층으로 분리된다 (의존 방향 단방향, 자세한 규칙은 [CLAUDE.md §8.1](CLAUDE.md)):
+
+```
+App-specific (e.g. EgBim) ──→ HmEG-aware ──→ Generic
+    (특정 앱만)                (HmEG 호스팅 앱 공통)     (임의 WPF 앱)
+```
+
+`Recordingtest.Architecture.Tests` 가 `Assembly.GetReferencedAssemblies()` 검사로 빌드 시점에 규칙을 강제한다. 새 SUT를 추가할 때는 App-specific 계층에 플러그인 진입점 + 어댑터만 작성하고 Generic + HmEG-aware 전부 재사용.
+

+- **2026-04-08 — Raw 시나리오 E2E 성공** 🎉 수동 cleanup 없이 recorder 원본 `box-v6.yaml`이 그대로 재생되어 Box 생성 (이슈 #14). Player에 null-target fallback, SUT foreground 능동 대기, 선두 alt+tab 노이즈 자동 skip, 스텝 간 타이밍 보존 추가.

+## Notes
+
+- D4 partial: The contract specifies `{"error":"..."}` as the failure body, but the implementation emits `{"ok":false,"error":"..."}`. The extra `ok:false` field is additive and does not break any consumer — no test relies on the absence of `ok`. Marked partial rather than fail because it is a strict-reading deviation only, not a functional defect.
+
+- `StateRouterTests` has no explicit test for `POST /camera/restore` success/failure, but D9 only specifies recorder/player tests and D4 does not mandate a StateRouter unit test. The router logic is covered by code inspection.
+
+- The `CameraRestore_HostReturnsFalse_PlaybackContinues` test (PlayerEngineTests line 322) covers the Risks section's non-blocking playback requirement and verifies steps still execute when restore fails.
+
+- Architecture layer constraints remain intact: `IEngineStateProvider.SetCamera` is in the generic tier; `HmegDirectStateProvider.SetCamera` is in the HmEG-aware tier; no reverse dependencies introduced.

+# Sprint Contract — camera-restore
+
+## Goal
+
+Record the SUT camera state at the start of each recording session; at playback
+time, restore that camera state via the engine-bridge HTTP sidecar so that
+replays are position-independent even when the user left the viewport in a
+different orientation than when the scenario was recorded.
+
+## DoD (Definition of Done)
+
+All items must be met for Evaluator to mark this PASS.
+
+| # | Item |
+|---|------|
+| D1 | `IEngineStateProvider` has `SetCamera(CameraSnapshot)` method. `NullEngineStateProvider`, `ReflectionEngineStateProvider`, `ChainedEngineStateProvider` all compile. |
+| D2 | `HmegDirectStateProvider.SetCamera` applies eye/look/up/fov to the active `CameraCore` via reflection on the UI dispatcher thread. |
+| D3 | `BridgeHttpServer` reads the request body for POST requests and passes it to `StateRouter`. |
+| D4 | `StateRouter` handles `POST /camera/restore`: parses eye/target/up/fov from JSON body, calls `provider.SetCamera(...)`. Returns `{"ok":true}` on success, `{"error":"..."}` on failure. |
+| D5 | `HmEgHttpSnapshot.RestoreCamera(double[] eye, double[] target, double[] up, double fov)` POSTs to `/camera/restore`. |
+| D6 | Recorder `Scenario` model has `CameraSnapshot?` field (YAML: `camera_snapshot`). Recorder captures GET /camera at recording start (via `--sidecar-url` CLI arg, default `http://localhost:38080`) and stores it in `scenario.CameraSnapshot`. |
+| D7 | Player `Scenario` model has `CameraSnapshot?` field (YAML: `camera_snapshot`). `IPlayerHost` has `bool TryRestoreCamera(...)` with default `return false` implementation. `PlayerEngine.Run()` calls `host.TryRestoreCamera(...)` if `scenario.CameraSnapshot != null`, logs result. |
+| D8 | `UiaPlayerHost` accepts optional `string? sidecarUrl` constructor param. `TryRestoreCamera` POSTs to sidecar `/camera/restore`, returns true on HTTP 200, false otherwise. |
+| D9 | At least 3 new unit tests: sidecar-unavailable (recorder captures null camera → no `camera_snapshot` in YAML), player-skip (no camera snapshot in scenario → no restore attempt), player-restore (camera snapshot present → `TryRestoreCamera` called with correct values). |
+| D10 | All existing tests still pass. |
+
+## Interfaces
+
+```csharp
+// Bridge.Abstractions
+public interface IEngineStateProvider
+{
+    // ... existing ...
+    void SetCamera(CameraSnapshot snapshot);
+}
+
+// Player
+public interface IPlayerHost
+{
+    // ... existing ...
+    bool TryRestoreCamera(double[] eye, double[] target, double[] up, double fov) => false;
+}
+
+// HmEgHttpSnapshot (Hmeg.Bridge.Client)
+public void RestoreCamera(double[] eye, double[] target, double[] up, double fov);
+```
+
+### POST /camera/restore
+
+Request body:
+```json
+{"eye":[x,y,z],"target":[x,y,z],"up":[x,y,z],"fov":45.0}
+```
+
+Response (200):
+```json
+{"ok":true}
+```
+
+## Risks
+
+| Risk | Mitigation |
+|------|-----------|
+| WPF DependencyProperty must be set on UI thread | `HmegDirectStateProvider.SetCamera` accepts `Action<Action>? uiDispatch`; `HmEgBridgePlugin` passes `Application.Current.Dispatcher.Invoke`. |

+# Sprint Contract — engine-bridge-v3
+
+## Goal
+
+`Recordingtest.EgPlugin.ReflectionEngineStateProvider`를 v2의 stub에서 진짜 reflection 기반 매핑으로 격상한다. SUT(EG-BIM Modeler)의 HmEG 엔진 내부 상태(카메라/선택/씬)를 in-process plugin에서 reflection으로 읽어 HTTP `/state` 응답에 실제 값을 채운다. 이 값이 골든파일 sidecar JSON으로 들어가 회귀 비교의 핵심 결정성 신호가 된다.
+
+## Background
+
+- v1: 정적 분석으로 HmEG 어셈블리 멤버 후보 8000+ 카탈로그 (`docs/engine-catalog/hmeg-candidates.json`).
+- v2: MEF plugin masquerade + HttpListener + 8 + 3 tests. `ReflectionEngineStateProvider`는 stub만.
+- v3: stub을 실매핑으로 교체. SUT 환경에서 라이브 검증 필요.
+
+## Definition of Done
+
+각 항목은 객관적으로 검증 가능해야 한다.
+
+### D1. AppManager 발견
+- plugin이 SUT 프로세스 안에서 `AppManager`(또는 동등한 root) 인스턴스를 reflection으로 획득한다.
+- 실패 시 `NullEngineStateProvider`로 안전하게 폴백하고 stderr에 한 번만 경고 로그.
+
+### D2. CameraSnapshot 실매핑
+- `GetCamera()`가 활성 뷰포트의 카메라 eye/target/up/fov를 **non-default 값**으로 반환.
+- 검증: 라이브 SUT에서 카메라 이동 후 두 번 호출 → 적어도 한 필드가 달라짐.
+
+### D3. SceneSnapshot 실매핑
+- `GetScene()`가 현재 문서의 객체 수와 (열린 경우) 문서 경로를 반환.
+- 검증: Box 1개 생성 후 `ObjectCount >= 1`, 새 문서 만들면 0.
+
+### D4. SelectedIds 실매핑
+- `GetSelectedIds()`가 현재 선택된 객체의 ID 리스트를 반환 (HmEG 내부 ID 또는 GUID 문자열).
+- 검증: 객체 선택 → 비어있지 않은 리스트.
+
+### D5. 결정성 + 정규화
+- 응답 JSON은 normalizer가 처리 가능한 형태 (정렬된 키, 안정된 부동소수점 표현). normalizer 규칙은 기존 `mask_volatile_settings` / 부동소수점 epsilon으로 충분한지 확인하고 부족하면 신규 규칙 등록.
+
+### D6. 단위 테스트
+- `ReflectionEngineStateProvider`의 reflection 경로를 mockable한 `IAppManagerAccessor` 추상화 뒤로 격리.
+- Fake accessor로 각 D2/D3/D4를 단위 테스트화 (라이브 SUT 없이 CI 가능).
+- 최소 6 신규 테스트, 전체 suite green (현 94+ → 100+).
+
+### D7. 라이브 검증
+- 사용자 SUT 환경에서 plugin 로드 → `/state` GET 응답에 D2/D3/D4 실값 확인.
+- 결과는 `docs/history/2026-04-08_engine-bridge-v3.md` 에 캡처.
+
+### D8. 문서
+- `docs/contracts/engine-bridge-v3.evaluation.md` (Evaluator 산출물)
+- `docs/guides/engine-bridge-deploy.md` 업데이트 (v3 응답 스키마 변경분)
+
+## Out of scope
+
+- HmEG 내부 데이터 변경/쓰기 (read-only)
+- viewport 픽셀 캡처 (별개 모듈)
+- 새 HTTP 엔드포인트 (기존 `/state` 라우트만 채움)
+
+## Interfaces
+
+```csharp
+// 새 추상화 (D6)
+public interface IAppManagerAccessor
+{
+    object? GetAppManager();
+    object? GetActiveDocument();
+    object? GetActiveViewport();
+}
+
+// 기존 IEngineStateProvider 시그니처 유지 — 구현만 교체
+```
+
+## Evaluation plan
+
+1. Evaluator는 `/contract engine-bridge-v3.md` 를 읽고 D1~D8을 차례로 채점.
+2. D2/D3/D4는 단위 테스트(D6)로 검증 가능 → CI에서 자동 grade.
+3. D7은 사용자 라이브 결과 첨부로 grade (orchestrator가 캡처 전달).
+4. fail 1회 → Generator 재작업. 누적 3회 → 자동 중단.
+
+## Risks
+
+- HmEG 내부 타입 이름이 obfuscation/난독화 가능 → reflection by-name이 깨질 수 있음. 완화: `hmeg-candidates.json` 카탈로그를 dictionary로 lookup, fallback 체인 다중화.
+- AppManager singleton 접근 패턴이 SUT 버전마다 다를 수 있음. 완화: D1에서 여러 후보 시도.
+- 카메라 좌표계가 right-handed/left-handed/up-axis 다양 → 정규화 규칙 필요.
+
+## Estimated complexity
+
+중. 단위 테스트만으로는 D2/D3/D4의 실매핑이 옳은지 확인 불가 — 라이브 검증(D7)이 critical path. 1차 사이클은 발견(discovery)에 시간 쏠릴 가능성.

+# Sprint Contract — generic-sut-split (3-tier)
+
+## Goal
+
+`CLAUDE.md §8.1` 신규 규칙(**Generic / HmEG-aware / App-specific 3계층 분리**)을 코드베이스에 실제로 반영한다. 향후 EG-BIM Modeler 외에도 HmEG를 호스팅하는 다양한 WPF 응용을 추가할 때 Generic 코어와 HmEG-aware 미들 계층을 재사용하고, 앱마다 다른 부분(플러그인 진입점, 명령 lifecycle 어댑터)만 새로 작성하면 되도록 한다.
+
+## Background
+
+지금까지 모든 모듈이 `src/Recordingtest.*` 평면에 있고, `Recordingtest.EgPlugin`/`Recordingtest.EngineBridge`가 "EG-BIM 전용"과 "HmEG 일반"과 "Generic"이 섞인 채로 존재한다. 사용자 디렉티브:
+1. 처음부터 Generic vs SUT-specific 분리
+2. **HmEG는 사용자 WPF 앱군의 공통 엔진** — HmEG-aware 미들 계층을 따로 두어 앱 간 재사용
+
+따라서 분리는 2-tier가 아니라 **3-tier**: Generic → HmEG-aware → App-specific (EgBim).
+
+## Definition of Done
+
+### D1. 폴더/csproj 이동·분할
+
+**Generic 신설**:
+- `src/Recordingtest.Bridge.Abstractions/` — `IEngineStateProvider`, `CameraSnapshot`, `SceneSnapshot`, 향후 `IFocusProbe`/`IHitTestProbe`/`ICommandLifecycle`. **`HmEG.dll` 참조 금지**.
+- `src/Recordingtest.Bridge.Client/` — generic HTTP 클라이언트 (`HttpClient` 래퍼, `BridgeClientException`, `IBridgeClient`)
+
+**HmEG-aware 신설** (`src/Hmeg/` 하위):
+- `src/Hmeg/Recordingtest.Hmeg.Bridge/` — `HmegDirectStateProvider : IEngineStateProvider` (HmEG `Space`/`HmEGViewport`/`CameraCore` 직접 호출), HTTP 서버는 별도. **`HmEG.dll`만 참조**.
+- `src/Hmeg/Recordingtest.Hmeg.TargetResolver/` — 씬 노드 hit-test/포커스 식별 (Gap I 우회의 HmEG-aware 레이어)
+- `src/Hmeg/Recordingtest.Hmeg.Catalog/` — `Recordingtest.EngineBridge`의 정적 분석/CandidateFinder를 이쪽으로 이동
+- `src/Hmeg/Recordingtest.Hmeg.Bridge.Client/` — `HmEgHttpSnapshot` 등 HmEG-shaped 응답 타입 (현 `Recordingtest.EngineBridge.Client`에서 분리)
+
+**App-specific (EgBim) 신설** (`src/Sut/EgBim/` 하위):
+- `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/` — MEF entry. `EditorPlugin` 베이스 상속, `BridgeHttpServer` 부팅. 현재 `Recordingtest.EgPlugin.HmEgBridgePlugin` 이동.
+- `src/Sut/EgBim/Recordingtest.Sut.EgBim.Adapter/` — EG-BIM Modeler `AppManager` 진입점, command lifecycle 어댑터. 현재 `ReflectionAppManagerAccessor`는 여기로 (CI fallback 용도). EG-BIM 전용 SUT 멤버 이름 후보(예: `Editor.AppManager.AppManager`)는 이 모듈에만 등장.
+
+**테스트 이동**:
+- `tests/Recordingtest.Bridge.Abstractions.Tests/` (신규)
+- `tests/Hmeg/Recordingtest.Hmeg.Bridge.Tests/` (현 EgPlugin 테스트의 HmEG 부분)
+- `tests/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost.Tests/` (현 EgPlugin 테스트의 EgBim 부분)
+- `tests/Hmeg/Recordingtest.Hmeg.Catalog.Tests/` (현 EngineBridge.Tests 이동)
+- `tests/Hmeg/Recordingtest.Hmeg.Catalog.IntegrationTests/` (현 EngineBridge.IntegrationTests 이동)
+
+**제거**:
+- 기존 `src/Recordingtest.EgPlugin/`, `src/Recordingtest.EngineBridge/`, `src/Recordingtest.EngineBridge.Client/` 디렉터리 (내용물은 위 3계층으로 분배)
+
+### D2. 네임스페이스 rename
+- `Recordingtest.Bridge.*` (Generic)
+- `Recordingtest.Hmeg.*` (HmEG-aware)
+- `Recordingtest.Sut.EgBim.*` (App-specific)
+- 모든 `using Recordingtest.EgPlugin;` 정리
+- `recordingtest.sln` 프로젝트 경로/이름 갱신
+
+### D3. 인터페이스 추출
+- `IEngineStateProvider`, `CameraSnapshot`, `SceneSnapshot` → `Recordingtest.Bridge.Abstractions` (Generic)
+- 현재 `Recordingtest.EgPlugin` 내 정의 제거, 새 위치를 참조
+
+### D4. HmegDirectStateProvider 골격 신설
+- `src/Hmeg/Recordingtest.Hmeg.Bridge/HmegDirectStateProvider.cs` 작성 (구현은 람다 주입 형태, `docs/hmeg-api-survey.md` §"v3 구현 방향" 참고)
+- 단위 테스트 — fake viewport/space 람다로 D2/D3/D4(원래 v3 contract)에 해당하는 동작 검증
+- **본 contract에서는 골격만**. 실제 HmEG 라이브 검증은 `engine-bridge-v3` 후속 contract.
+
+### D5. EgBim PluginHost 보존
+- 현 `HmEgBridgePlugin`의 동작(MEF 발견, BridgeHttpServer 부팅, ReflectionEngineStateProvider 폴백)은 동일해야 함
+- provider 결정 로직: `HmegDirectStateProvider` 가능하면 사용, 실패 시 `ReflectionEngineStateProvider` 폴백, 최종 실패 시 `NullEngineStateProvider`
+
+### D6. 의존 그래프 검증
+- Generic 모듈의 csproj는 `HmEG.dll` 또는 `Editor*PluginInterface.dll` 을 **직간접 참조하지 않음**
+- HmEG-aware 모듈의 csproj는 `HmEG.dll`만 참조, 특정 앱 어셈블리 참조 금지
+- App-specific 모듈만이 자기 앱 어셈블리 참조
+- 신규 `Recordingtest.Architecture.Tests` — `Assembly.GetReferencedAssemblies()` 검사로 위반 검출. 각 계층별 expected reference set assert.
+
+### D7. 빌드/테스트 green
+- `dotnet build recordingtest.sln` 성공
+- `dotnet test recordingtest.sln` 100+ tests 모두 pass
+- 신규 ArchitectureTests + HmegDirectStateProvider 단위 테스트 통과
+
+### D6. 빌드/테스트 green
+- `dotnet build recordingtest.sln` 성공
+- `dotnet test recordingtest.sln` 100+ tests 모두 pass (현재 상태 유지)
+- 신규 ArchitectureTests 통과
+
+### D8. PROGRESS/PLAN 갱신 + history
+- PROGRESS.md Done에 항목 추가
+- PLAN.md에서 본 contract 제거
+- `docs/history/YYYY-MM-DD_generic-sut-split.md` 작성
+- CLAUDE.md §8.1 표(현재 모듈 분류)를 마이그레이션 후 상태로 갱신
+
+### D9. 단일 커밋(권장) 또는 2단 커밋
+- 옵션 A: 단일 커밋 — sln 무결성 보장, BREAKING 명시
+- 옵션 B: (1) git mv만, (2) 내용 변경 — git rename detection 보존
+- Generator 판단. 어느 쪽이든 메시지 prefix `BREAKING:`
+
+## Out of scope
+
+- 새 SUT(다른 WPF 앱) 추가 — 본 contract는 구조만 만든다
+- engine-bridge v3의 `HmEgDirectStateProvider` 구현 — 그건 별도 contract `engine-bridge-v3` 후속
+- generic 코어의 기능 변경 — 순수 rename/이동만
+
+## Interfaces
+
+```csharp
+// src/Recordingtest.Bridge.Abstractions/IEngineStateProvider.cs (generic)
+namespace Recordingtest.Bridge;
+
+public interface IEngineStateProvider
+{
+    IReadOnlyList<string> GetSelectedIds();
+    CameraSnapshot GetCamera();
+    SceneSnapshot GetScene();
+    bool GetRenderComplete();
+}
+
+public sealed record CameraSnapshot(double[] Eye, double[] Target, double[] Up, double Fov);
+public sealed record SceneSnapshot(int ObjectCount, string? DocumentPath);
+```
+
+```csharp
+// src/Sut/EgBim/Recordingtest.Sut.EgBim.Plugin/HmEgDirectStateProvider.cs (SUT)
+namespace Recordingtest.Sut.EgBim.Plugin;
+using Recordingtest.Bridge;
+public sealed class HmEgDirectStateProvider : IEngineStateProvider { ... }
+```
+
+## Risks
+
+- **sln 경로 깨짐**: csproj 이동 시 sln 갱신을 빠뜨리면 빌드 깨짐. 완화: D6에서 솔루션 빌드 + 테스트 강제.
+- **using 구문 누락**: 네임스페이스 rename 시 다른 프로젝트의 using이 깨짐. 완화: 빌드가 잡아냄.
+- **engine-bridge v3 진행 중 방해**: scaffold 미커밋 상태(IAppManagerAccessor 등). 본 refactor 전에 v3 scaffold를 먼저 커밋해 두는 게 안전.
+- **git rename detection**: 폴더 이동 + 내용 변경이 동시에 들어가면 git이 rename 인식을 못 할 수 있음. 완화: 가능한 한 "이동만" 한 번 커밋, "내용 변경"은 후속 커밋. (단일 커밋 vs rename 보존 trade-off — D8과 충돌 가능. Generator 판단.)
+
+## Estimated complexity
+
+중. 코드 로직 변경은 거의 없고 mass rename + 폴더 이동 + sln 정리. 시간보다 손실 위험 관리가 핵심.
+
+## Evaluation plan
+
+Evaluator는:
+1. D1~D5를 파일/폴더/csproj 검사로 채점
+2. D5의 ArchitectureTests 실행
+3. D6의 전체 build/test 실행
+4. D8의 git log 단일 커밋 확인
+
+fail 1회 → Generator 재작업. 누적 3회 → 자동 중단.

+# 2026-04-08 — Gap I-1 (recorder focus poller) deferred
+
+**소요 시간**: ~45분
+**Context 사용량**: ~25k tokens (Opus 4.6, 동일 세션 누적)
+
+## 시도
+
+issue #14의 recorder Gap I-1: type 스텝 target이 항상 null로 남는 문제를 root에서 풀기 위해 시도.
+
+접근:
+1. 백그라운드 Task가 100ms 주기로 `automation.FocusedElement()` 폴링
+2. 결과 path를 `LowLevelHook.CurrentFocusedPath` volatile 필드에 저장
+3. `KeyboardProc`가 key_down RawEvent 생성 시 이 필드를 `FocusedElementPath`에 stamp
+4. `DragCollapser`가 type burst 시작 시 `typeFocusPath` 로컬에 캡처, FlushType fallback에서 우선 사용
+5. 진단 카운터 추가 (success/null_focus/wrong_pid/errors/last_path)
+
+## 결과
+
+box-v7.yaml 녹화 → `null_target_steps=13` (이전 12와 사실상 동일). type 스텝의 `target:` 여전히 비어있음.
+
+## 원인
+
+UIA `FocusedElement()`는 **AutomationPeer가 부착된 컨트롤만** 보고할 수 있다. EG-BIM Modeler의 CommandBox 등 핵심 입력 컨트롤은 AutomationPeer가 없어서 UIA 트리에 의미 있게 노출되지 않음. 외부 프로세스에서 어떤 UIA API를 호출해도 동일한 한계.
+
+WPF의 진짜 포커스(`Keyboard.FocusedElement`)는 **in-process API**라 외부 recorder에서는 직접 호출 불가.
+
+## 결정
+
+**Gap I-1 deferred.** 현재는 Player fallback이 공식 전략:
+- Type with null target → OS 레벨 키보드 입력 (SUT의 WPF가 자기 포커스 컨트롤로 라우팅)
+- Click with null target + raw_coord → 화면 절대좌표 클릭
+
+이 fallback으로 box-v6/v7 모두 E2E 재생 성공 확인됨. 결정성/진단성은 떨어지지만 실행 자체엔 충분.
+
+## 향후 옵션 (선결 PoC 필요)
+
+1. **Generic WPF DLL injection** — CreateRemoteThread + LoadLibrary로 임의 WPF 프로세스에 probe DLL 주입, Dispatcher 위에서 `Keyboard.FocusedElement` 읽어 named pipe로 노출. 권한 이슈 있음.
+2. **AutomationPeer AI 부착 PoC** (메모리 `project_recordingtest_automationpeer_ai.md`) — SUT fork에 AI로 AutomationPeer 자동 부착하는 별도 PR 트랙. SUT 협조 필요.
+
+둘 다 본 이슈 범위를 벗어나므로 별도 트랙. PLAN.md에서 제거됨.
+
+## 남긴 코드
+
+진단 가능한 형태로 commit (revert하지 않음). 향후 generic injection PoC가 들어올 때 같은 stamping 메커니즘(`LowLevelHook.CurrentFocusedPath` → `RawEvent.FocusedElementPath` → `DragCollapser.typeFocusPath`) 그대로 재사용 가능.

+| G — player 재실행 | **Box 생성 완료 ✅** |
+
+## 발견된 추가 Gap (smoke 3회차 대상)
+
+### Gap E — `UiaPlayerHost.Hotkey` named key 미지원 (fix 완료)
+single-character만 처리하고 `"enter"`, `"tab"`, `"escape"` 같은 5글자 이름은 default 브랜치에서 길이 체크 탈락 → **아무 키도 누르지 않음**.
+
+**Fix**: switch에 20+ named key 매핑 추가 (return/tab/esc/space/backspace/delete/home/end/arrows/F1-F9). commit 대기 중.
+
+### Gap F — recorder focus_change 필터 미작동
+`box-v5.yaml` 상단에 VS Code / PowerShell / 기타 창의 focus_change 스텝 40+ 개. Gap C (#12)가 mouse/key만 필터하고 focus는 UIA 콜백이라 SUT-scoped라 가정했지만 **실측 결과 시스템 전역 focus 이벤트 수신**.
+
+### Gap G — 뷰포트 클릭이 Console Window로 잡힘
+사용자가 뷰포트 위를 클릭해도 recorder의 `FromPoint`가 PowerShell 콘솔을 반환하는 경우 발견. Console이 최근 활성이었거나 top-level z-order 때문으로 추정. `WindowFromPoint` 기반 필터도 부족.
+
+### Gap H — cleaned yaml의 offset은 추측값
+뷰포트 클릭 offset `(0.35, 0.55)`, `(0.5, 0.35)`는 orchestrator가 임의 지정. 실제 geometry가 원본과 다른 모양 (길쭉한 박스)으로 생성된 원인. 원본 녹화의 정확한 offset을 쓰려면 뷰포트 호스팅 컨트롤을 recorder가 올바르게 식별해야 함 (Gap G와 연결).
+
+## 결정적 진전
+
+이번 라운드가 입증한 것:
+1. **recorder + player 코어 파이프라인이 실전 작동**
+2. **UiaPathResolver ancestor chain 매칭이 정확** (CommandBox/CB 정확히 찾음)
+3. **DragCollapser type target 상속 완벽 작동**
+4. **FlaUI 입력 합성이 안정적** (clicks/type/hotkey)
+5. **harness design 사이클의 가치** — 샌드박스 77 tests green에도 라이브에서 hotkey bug 발견, 즉석 fix, 재실행으로 E2E 성공
+
+## Box 모양이 다른 이유
+
+좌표 재현의 본질적 한계가 아님. 단순히 cleaned yaml의 offset이 추측값이었기 때문. recorder가 뷰포트를 올바른 컨트롤로 잡기만 하면 offset_norm으로 완벽 재현 가능.
+
+## 다음 단계 권장
+
+**이슈 #13 등록** — Gap E(hotkey fix는 즉시 commit) + F/G/H:
+- Gap E: hotkey named key (fix 완료, commit 필요)
+- Gap F: focus_change 이벤트 SUT 필터
+- Gap G: `FromPoint`가 Console/Foreground 반환하는 경우 재귀 검색
+- Gap H: (Gap G 해결되면 자동 해결)
+
+그 후 smoke 3회차로 **원본 녹화 그대로 재생 가능한지** 검증.
+
+## 종합 평가
+
+**Smoke 2회차 성공**. PoC가 샌드박스에서만 아니라 실전에서도 기초 경로 동작함을 실증. E2E 최초 Box 생성은 프로젝트 milestone.

+# 2026-04-08 이슈 #13 — smoke 2차 gap fix (Generator + orchestrator 수습)
+
+- **이슈**: #13
+- **소요 시간**: ~40분 (Generator 3회 시도 중 첫 2번 API 529 overload, 3번째가 실질 완료 후 529로 종료되어 orchestrator가 history/commit만 수습)
+- **Context 사용량**: ~500k tokens (orchestrator 누적)
+
+## 요약
+
+Smoke 2회차 후속 4개 gap 중 E/F/G 수정. Generator 서브에이전트가 세 번째 시도에서 약 30회 tool 호출 후 Anthropic API 529 overload로 조기 종료되었으나, 실제 코드 작성은 사실상 완료된 상태였음. Orchestrator가 빌드/테스트 검증 후 history/commit 단계만 수습.
+
+## 수정 내역
+
+### Gap E — Hotkey named key (단위 테스트 추가)
+`src/Recordingtest.Player/UiaPlayerHost.cs`:
+- `internal sealed record ParsedHotkey(IReadOnlyList<VirtualKeyShort> Modifiers, VirtualKeyShort? Main)` 신규
+- `internal static ParsedHotkey ParseHotkey(string keys)` 메서드로 기존 switch body 추출
+- `Hotkey(string keys)` 는 이제 `ParseHotkey` 호출 후 press/release만 수행
+- 신규 테스트: `tests/Recordingtest.Player.Tests/HotkeyParseTests.cs` — **8 tests** (enter/tab/a/ctrl+c/ctrl+shift+s/f5/alt+f4/empty)
+
+### Gap F — recorder focus_change SUT 필터
+`src/Recordingtest.Recorder/FocusEventFilter.cs` 신규:
+```csharp
+public static bool ShouldAccept(int candidatePid, int sutPid) {
+    if (sutPid <= 0) return true;       // unknown SUT: permissive
+    if (candidatePid <= 0) return false; // unknown element pid: drop
+    return candidatePid == sutPid;
+}
+```
+`Program.cs`의 `automation.RegisterFocusChangedEvent` 콜백에서 element.ProcessId 확인 후 `FocusEventFilter.ShouldAccept` 호출 — false면 큐 쓰기 skip.
+
+신규 테스트: `tests/Recordingtest.Recorder.Tests/FocusEventFilterTests.cs` — **4 tests** (same/different/unknownCandidate/unknownSut)
+
+### Gap G — viewport picking foreign-process fallback
+`src/Recordingtest.Recorder/WindowPointResolver.cs` 신규:
+- `IWindowPointSource` 인터페이스 (`GetProcessIdAt`, `GetElementAt`, `GetElementFromSutScope`)
+- `WindowPointResolver.Resolve(source, x, y, sutPid)` — primary element의 process가 SUT가 아니면 SUT-scoped fallback 시도, fallback null이면 primary 유지 (last resort)
+
+`Program.cs` 내부 `FlaUiPointSource` 구현체로 wire. `GetElementFromSutScope`는 현재 mainWindow 기반 best-effort hit-test (라이브 SUT 없이 완전 검증 불가 → **honest partial**).
+
+신규 테스트: `tests/Recordingtest.Recorder.Tests/WindowPointResolverTests.cs` — **5 tests** (samePid/differentPid/unknownPid/zeroPid/fallbackNull)
+
+## 테스트 결과
+
+| 프로젝트 | Before | After |
+|---------|--------|-------|
+| Player.Tests | 16 | **24** |
+| Recorder.Tests | 17 | **26** |
+| 기타 | 변경 없음 | |
+| **합계** | **77** | **94** |
+
+Build: 0 warn / 0 err. 모든 테스트 green.
+
+## Honest partial — Gap G
+
+`FlaUiPointSource.GetElementFromSutScope`는 라이브 SUT 환경에서만 완전 검증 가능. Pure `WindowPointResolver` 로직은 fake-backed로 완전히 테스트됨. smoke 3회차에서 실환경 검증 예정.
+
+## Regression trap
+
+- HotkeyParseTests: 각 테스트가 pre-refactor의 `p.Length == 1` 체크만으로는 실패 — named key entries 필수
+- FocusEventFilterTests: 기존 `Program.cs`에는 이 static이 없었으므로 compile trap
+- WindowPointResolverTests: 기존에 없던 새 타입 → compile trap + behavior assertion
+
+## 커밋 (wip)
+
+Generator가 커밋 전 529로 터져서 orchestrator가 대신 커밋.
+
+## Anthropic API 주의
+
+3회 연속 시도 중 2회 즉시 529, 3회째는 작업 거의 완료 후 529로 종료. 서브에이전트 세션의 "중단 후 부분 작업 보존" 동작이 유용함을 실증 — 파일이 디스크에 이미 쓰인 상태라 orchestrator가 이어받아 마무리 가능.

+## Harness 원칙 관련 관찰
+
+Anthropic API 529가 연속 발생하는 상황에서도 **서브에이전트의 중간 파일 쓰기가 보존**되어 orchestrator가 이어받아 마무리 가능했음. Generator가 완벽히 작업을 완료하지 못했음에도, 3번째 시도가 실질 핵심 작업을 디스크에 쓴 시점에 529로 중단 → orchestrator가 build/test로 검증 후 부족한 부분(history/commit)만 수행. "세션 경계에서의 graceful degradation" 사례.
+
+## 비용
+
+Generator 3회 합계 ~2.2k (대부분 529 조기 종료) + Orchestrator 수습 ~12k + Evaluator ~40k = **~54k**. 예외적으로 저비용.
+
+## 다음 단계
+
+**Smoke 3회차** — 사용자 환경에서 box-v5.yaml 원본 또는 유사 녹화를 재생하여 Gap F/G fix가 실제로 동작하는지 검증.

+# 2026-04-08 — 이슈 #14 Raw 시나리오 E2E 성공
+
+**이슈**: #14 Raw 레코딩 시나리오를 수동 cleanup 없이 재생 가능하게
+**소요 시간**: ~90분
+**Context 사용량**: ~60k tokens (Opus 4.6)
+
+## 결과
+
+🎉 **`scenarios/box-v6.yaml` 원본(AI 후처리 없음)** → Player 재생 → **SUT에 Box geometry 생성 확인**.
+
+이전 box-v5-clean.yaml E2E 성공은 AI가 focus 이벤트 40+개 제거, target UIA 경로 리타기팅(ItemsControl→CommandBox), 뷰포트 offset 박음질 등 수작업 후편집의 결과였다. 이번 작업으로 **수작업 없이 recorder 원본을 그대로 재생**하는 경로가 처음으로 열렸다.
+
+## 문제 분해
+
+레코더 원본은 다음 4가지 이유로 재생 불가였다:
+
+1. **Type/Click null target** — recorder가 key/mouse 이벤트 발생 시 focused element를 resolve 못 해 `target: null`로 저장. Player는 "#11에서 null skip" 정책이라 아예 실행 안 함.
+2. **Player 실행 시 포커스** — `dotnet run` 한 PowerShell이 foreground라 첫 type("BOX")이 PowerShell로 들어감.
+3. **선두 alt+tab 노이즈** — 녹화 시작 시 사용자가 에디터→SUT로 전환하려던 alt+tab 2개가 재생 시 SUT를 오히려 off-foreground로 보냄.
+4. **스텝 간 타이밍 없음** — 엔진이 즉시 연속 실행 → SUT가 BOX 명령 → 모서리 픽 전환할 틈 없음.
+
+## 구현 (Player 쪽 포스트프로세싱)
+
+### 1. Null-target fallback (PlayerEngine)
+- `Type + null target` → 현재 포커스로 그대로 `host.Type()` (SUT CommandBox 포커스 가정)
+- `Click + null target + raw_coord` → screen-absolute 좌표로 직접 `host.Click()`
+- 기타 null target → 여전히 skip (안전)
+- `Step.RawCoord: int[]?` 추가, YAML `raw_coord` 자동 매핑
+
+### 2. SUT foreground 강제 (UiaPlayerHost.BringSutToForeground)
+- `_app.GetMainWindow().SetForeground() + Focus()`
+- 600ms settle (150 → 600으로 상향; 초기 char 드롭 관찰 후)
+- Program.cs가 engine.Run 이전에 1회 호출
+
+### 3. 선두 alt+tab 자동 skip (PlayerEngine.Run)
+- 녹화 startup 노이즈 제거. SUT가 이미 foreground인 상태에서 alt+tab 실행은 오히려 유해.
+
+### 4. 스텝 간 타이밍 복원 (PlayerEngine + IPlayerHost.Delay)
+- `Step.Ts: long?` 추가
+- `PlayerEngineOptions.PreserveTiming` (기본 on)
+- `ts_i - ts_{i-1}` 를 150ms~3s로 클램프해 host.Delay 호출
+- **엔진 내부 `Thread.Sleep` 금지 DoD를 유지하기 위해** 딜레이는 `IPlayerHost.Delay`로 위임. `UiaPlayerHost`만 실제 sleep, `FakePlayerHost`는 기록만.
+- 첫 스텝도 MinStepDelay 받도록 prevTs 시드
+
+### 5. 스텝 로그
+- `[player] step {i} kind={kind} value={value}` — 라이브 디버깅용
+
+## 테스트
+
+- `PlayerEngine_NullTarget_SkipsWithoutCalling` → `PlayerEngine_NullTarget_Fallback_Issue14`로 교체
+  - click(null+raw_coord) → clicks[0] 검증, type(null+value) → types[0] 검증
+  - click(null, no raw_coord), drag(null) → 여전히 skip
+- 전체 suite green: 94+ tests (Player 24, Runner 6, Recorder 26, Normalizer 16, ...)
+
+## 라이브 검증 (사용자 환경)
+
+```
+dotnet run --project src\Recordingtest.Player -- --scenario scenarios\box-v6.yaml --output-dir artifacts\replay-v6-raw --no-launch
+```
+
+첫 시도는 BOX 타이핑이 누락 (`[player] step 2 kind=Type value=BOX` 로그는 찍혔지만 SUT command box에 안 들어감). 두 번째 시도에서 Box geometry 생성 성공.
+
+## 남은 과제 (PLAN.md P1에 등록)
+
+- **foreground settle 경계선 문제** — 600ms가 가끔 부족. `SetForegroundWindow` 후 능동 대기(`GetForegroundWindow == sut_hwnd` polling) 또는 첫 type 이전에 Keyboard warm-up 필요.
+- **recorder Gap I-1** — null_target_steps를 근본적으로 줄이려면 recorder가 key_down 시점에 `Automation.FocusedElement`를 직접 쿼리해서 typeRes를 채워야 함. 현재는 player fallback으로 우회 중.
+
+## 관련 커밋

+# 2026-04-09 — 3-tier 분리 1단계 (incremental)
+
+**이슈**: #10 follow-up (engine-bridge v3) + 사용자 디렉티브 (Generic / HmEG-aware / App-specific 분리)
+**소요 시간**: ~70분
+**Context 사용량**: input ~205k / output ~38k tokens (Opus 4.6, 1M context, 동일 세션 누적)
+
+## 작업
+
+CLAUDE.md §8.1 의 3-tier 규칙을 incremental하게 코드에 반영. 기존 `EgPlugin`/`EngineBridge` mass-rename은 2단계로 미루고, **새 계층 모듈을 신설**해 wire-up까지 끝냄.
+
+### 신설 (Generic 계층)
+
+- `src/Recordingtest.Bridge.Abstractions/` (csproj, net8.0)
+  - `IEngineStateProvider`, `CameraSnapshot`, `SceneSnapshot`, `NullEngineStateProvider`
+  - SUT 어셈블리 참조 0개. CI 안전.
+- 기존 `Recordingtest.EgPlugin`의 `IEngineStateProvider`/`CameraSnapshot`/`SceneSnapshot`/`NullEngineStateProvider` 정의 제거 → Bridge.Abstractions로 위임 (`using Recordingtest.Bridge;`)
+
+### 신설 (HmEG-aware 계층)
+
+- `src/Hmeg/Recordingtest.Hmeg.Bridge/` (csproj, net8.0-windows + WPF + HmEG.dll 직접 참조)
+  - `HmegDirectStateProvider : IEngineStateProvider`
+    - 람다 주입: `Func<HmEG.Space?>`, `Func<HmEG.HmEGViewport?>`, `Func<string?>?`
+    - `GetSelectedIds`: Space 트리 walk → `ISelectable.IsSelected` 노드의 `Uid` 수집. `ModelBase` 직접 타입 참조 회피 (MemoryPack 의존 차단), 대신 `object` + 패턴 매칭 + 늦은 바인딩 `Uid` 프로퍼티 읽기
+    - `GetCamera`: `viewport.CameraCore`에서 `Position`/`LookDirection`/`UpDirection`/`FieldOfView`를 reflection으로 읽어 `CameraSnapshot`. Target = Eye + LookDir.
+    - `GetScene`: `space.ItemsCount` + 외부 documentPathProvider 람다
+    - 모든 호출 try/catch → safe default 폴백
+- `tests/Hmeg/Recordingtest.Hmeg.Bridge.Tests/` (csproj, HmEG.dll Private=true로 출력 폴더 복사)
+  - `HmegDirectStateProviderTests` 5개 (null lambdas / throwing lambdas / document path / null arg)
+
+### EgPlugin wire-up
+
+- `HmEgBridgePlugin.BuildProvider()` 신설:
+  ```
+  HmegDirectStateProvider (1순위, lambdas는 일단 null 반환)
+    ↓ default → 
+  ReflectionEngineStateProvider (2순위, EgBim AppManager 후보 탐색)
+  ```
+  체인: `ChainedEngineStateProvider`
+- `ChainedEngineStateProvider` 신설 — primary 결과가 default/empty면 fallback 호출. signal별 판정:
+  - SelectedIds 빈 리스트
+  - Camera Eye=(0,0,0) AND Target=(0,0,0)
+  - Scene ObjectCount=0 AND DocumentPath=null
+  - RenderComplete: primary always wins
+- 단위 테스트 7개 (`ChainedEngineStateProviderTests`)
+
+EgBim adapter(Q1~Q7 답)가 채워지면 `BuildProvider`의 두 람다만 실값으로 바꾸면 라이브 검증으로 이어진다.
+
+### sln/build/test
+
+- `dotnet sln add` 로 3개 신규 csproj 등록
+  - `Recordingtest.Bridge.Abstractions`
+  - `Recordingtest.Hmeg.Bridge`
+  - `Recordingtest.Hmeg.Bridge.Tests`
+- `dotnet build` 성공 (HmEG.dll의 ModelBase가 MemoryPack 의존성을 transitively 요구해서 1차 빌드 실패 → ModelBase 직접 참조 제거로 우회)
+- `dotnet test recordingtest.sln`: **0 failures, 115 passed** (94 → 115, +21)
+

+## 작업
+
+### 1. 3-tier 분리 2단계 (mass-rename + move)
+
+기존 EgPlugin/EngineBridge 모듈을 새 계층 폴더로 이동하고 네임스페이스를 일괄 rename.
+
+**소스 이동 (git mv)**:
+| 원본 | 대상 | 계층 |
+|---|---|---|
+| `src/Recordingtest.EgPlugin/` | `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/` | App-specific |
+| `src/Recordingtest.EngineBridge/` | `src/Hmeg/Recordingtest.Hmeg.Catalog/` | HmEG-aware |

+- `Recordingtest.EngineBridge` → `Recordingtest.Hmeg.Catalog`
+- `Recordingtest.EngineBridge.Client` → `Recordingtest.Hmeg.Bridge.Client`
+- `Recordingtest.EngineBridge.Probe` → `Recordingtest.Hmeg.Catalog.Probe`
+
+**csproj rename** + `<RootNamespace>` / `<AssemblyName>` + ProjectReference 경로 갱신 + `recordingtest.sln` 에서 remove/add.
+
+**문제/해결**:
+- `git mv`가 bin/obj 폴더 때문에 일부 실패 → 해당 폴더 삭제 후 재시도
+- `EngineBridge.Client` 전체 폴더 이동이 계속 permission denied → 파일 단위로 `git mv`해서 해결
+- `Directory.Build.props`의 자동 RootNamespace와 csproj의 수동 RootNamespace 정리 (Sut.EgBim.PluginHost는 수동, Hmeg.Catalog는 수동 덮어쓰기)
+
+### 2. Architecture Tests 추가
+
+`tests/Recordingtest.Architecture.Tests/` — 3-tier 규칙 강제.
+
+- Generic 모듈 (`Bridge.Abstractions`, `Recorder`, `Player`, `Normalizer`, `DiffReporter`, `Runner`, `SutProber`) 각각이 `HmEG.dll` 또는 `Editor03.PluginInterface` / `Editor02.HmEGAppManager` / `EditorCore` 를 **참조하지 않음** (Theory, 7건)
+- HmEG-aware 모듈 (`Hmeg.Bridge`, `Hmeg.Catalog`, `Hmeg.Bridge.Client`) 각각이 app-specific DLL을 **참조하지 않음** (3건)
+- `Hmeg.Bridge` 는 `HmEG.dll` 을 **참조함** (positive check, 1건)
+
+총 11건, 모두 pass. 향후 누가 실수로 generic 모듈에 HmEG 참조를 추가하면 여기서 red.
+
+### 3. engine-bridge v3 EgBim 람다 wire-up (Q1~Q7 답)
+
+사용자가 `D:\GiteaAll\EG-BIM_Modeler\EditorPluginInterface` 경로 공유 → read-only survey.
+
+**확정 (single-file find)**: `EditorPluginInterface/EditorPlugin.cs`
+
+```csharp
+public HmEGAppManager AppManager { get => TriggerStateService.AppManager; set; }
+public Space RootSpace { get => AppManager.ViewportManager.RootSpace; }
+public ViewportManager ViewportManager { get => AppManager.ViewportManager; }
+public EGViewport View { get; set; }     // deprecated but still usable
+```
+
+**HmEGAppManager** (`D:\GiteaAll\EG-BIM_Modeler\HmEGApplicationManagementLibrary\HmEGAppManager.cs`):
+- `ViewportManager` — RootSpace 진입점
+- `SelectionManager` — 중앙 선택 상태 (필요 시 hook, 현재는 walk)
+- `FileManager` — 저장 파일 경로
+- `AppModeManager` — 명령 lifecycle (Q4 후속)
+
+**`EGViewport : Control, HmEGViewport`** (`HmEG/Controls/HmEGViewport.cs:43`) — 그대로 HmEG-aware provider에 넘길 수 있음.
+
+**`FileManager.CurrentFile : string`** — 저장 문서 경로.
+
+**Q 답 매핑**:
+- Q1 Space: `this.RootSpace` ✅
+- Q2 Viewport: `this.View` (EGViewport: HmEGViewport) ✅
+- Q3 Selection: 중앙 리스트 없음. Space walk + `ISelectable.IsSelected` (이미 구현됨)
+- Q4 Command lifecycle: `AppModeManager`, `TriggerStateService.TriggerEnded` (별도 contract)
+- Q5 Fov: `PerspectiveCamera` cast, `HmegDirectStateProvider.GetCamera`의 reflection `FieldOfView` 후보 chain이 이미 잡음
+- Q6 DocumentPath: `AppManager.FileManager.CurrentFile` ✅
+- Q7 EGViewport↔HmEGViewport: `EGViewport : Control, HmEGViewport` ✅
+
+**구현**: `HmEgBridgePlugin.BuildProvider()`가 이제 실 람다 주입:
+
+```csharp
+Func<Space?> spaceProvider = () => { try { return RootSpace; } catch { return null; } };
+Func<HmEGViewport?> viewportProvider = () => { try { return View; } catch { return null; } };
+Func<string?> documentPathProvider = () =>
+{
+    try { var p = AppManager?.FileManager?.CurrentFile; return string.IsNullOrEmpty(p) ? null : p; }
+    catch { return null; }
+};
+```
+
+**csproj 추가 참조**: `Editor02.HmEGAppManager.dll` — `HmEGAppManager.FileManager.CurrentFile` 접근을 위해. app-specific tier이므로 허용 (ArchitectureTests는 이 tier를 검사하지 않음).

+```
+
+이것이 곧 golden-file 회귀 테스트의 결정성 신호 축이 된다.
+
+## 과정
+
+### 1. 배포 스크립트 `scripts/deploy-egbim-plugin.bat`
+
+사용자가 더블클릭 한 번에 빌드→복사 가능하도록:
+1. `EG-BIM Modeler.exe` 실행 여부 체크 (DLL 잠금 방지)
+2. `dotnet build` Debug
+3. 기존 `Plugins/Recordingtest.EgPlugin/` (legacy) + 기존 `Plugins/Recordingtest.Sut.EgBim.PluginHost/` 삭제
+4. 3개 DLL(+PDB) 복사:
+   - `Recordingtest.Sut.EgBim.PluginHost.dll` (App-specific)
+   - `Recordingtest.Hmeg.Bridge.dll` (HmEG-aware)
+   - `Recordingtest.Bridge.Abstractions.dll` (Generic)
+5. 배포 목록 + curl 명령 안내
+
+`HmEG.dll` / `Editor*.dll`은 SUT에 이미 있으므로 복사 안 함.
+
+### 2. 1차 라이브 결과 (camera 실패)
+
+```
+/scene    → object_count=4 ✅
+/camera   → eye/target/up 전부 (0,0,0) ❌
+/selection → 2 GUID ✅
+```
+
+`/scene` 이 작동했으므로 `AppManager.ViewportManager.RootSpace` 경로는 OK. 즉 `spaceProvider` 정상.
+
+`/camera` 는 default fallback. 원인: `HmEgBridgePlugin`의 `viewportProvider = () => this.View`에서 `View`가 항상 null.
+
+### 3. 원인 분석
+
+`EditorPlugin.View` 는 **플러그인이 `Run()` 될 때만 주입**되는 값. 우리 bridge plugin은 constructor에서 HTTP server만 돌리고 MEF trigger로 실행되지 않으므로 `View` 세터가 한 번도 호출되지 않음.
+
+반면 `AppManager` 는 `TriggerStateService.AppManager` 를 통해 얻어지며 SUT 전역 상태라 즉시 접근 가능. 그래서 `RootSpace` 는 동작하지만 `View` 만 null이었던 것.
+
+### 4. Fix — ViewportManager.FocusedViewport 경유
+
+`D:\GiteaAll\EG-BIM_Modeler\HmEGApplicationManagementLibrary\SubManager\ViewportManager.cs` (read-only) 확인:
+
+```csharp
+public HashSet<EGViewport> Viewports { get; set; }
+public EGViewport FocusedViewport { get; ... }
+public ObservableCollection<HmModel> SelectedModels { get; ... }
+```
+
+`FocusedViewport` 는 활성 뷰포트를 직접 노출. `viewportProvider` 를 다음으로 교체:
+
+```csharp
+var vm = AppManager?.ViewportManager;
+if (vm is null) return null;
+var focused = vm.FocusedViewport;
+if (focused is not null) return focused;
+foreach (var v in vm.Viewports) if (v is not null) return v;
+return null;
+```
+
+### 5. 2차 라이브 결과 — 전부 성공
+
+재빌드 → 배포 → SUT 재실행 → curl:
+- `/camera` eye/target/up 실 좌표
+- `fov=45` (PerspectiveCameraCore 기본값이 45라 실값인지 fallback인지 구분 안 되지만 reflection이 Position/LookDirection/UpDirection에서 성공한 이상 FieldOfView 도 동일 경로로 성공했다고 판단)
+- `/selection` 2 GUID 유지
+- `/scene` object_count=4 유지
+
+### 6. 부수 관찰
+
+- `document_path="NewSpace0"` — `FileManager.CurrentFile` 이 빈 파일에 대해 Space 이름을 반환하는 듯. 저장된 `.hmeg` 파일일 때 진짜 경로 확인 필요 (follow-up).
+- `HmegDirectStateProvider` 의 Selection walk (Space.Children 재귀 + `ISelectable.IsSelected`) 가 잘 동작. 대안 `ViewportManager.SelectedModels` 로 단순화 가능하나 현재 walk 방식이 결정적이고 테스트 친화적이라 그대로 유지.
+
+## 남은 것 (다음 단계 P1)
+
+- **Runner ↔ engine-bridge sidecar 연결** — 시나리오 재생 종료 시점에 `/scene` `/camera` `/selection` 한 번 더 호출해 sidecar JSON으로 베이스라인에 포함. `.received.json` 정규화 규칙 추가. 이게 진짜 golden-file 회귀 파이프라인의 마지막 조각.
+- `document_path` 의 unsaved vs saved 문서 케이스 확인
+- (선택) `SelectionManager.SelectedModels` 직접 사용 옵션 비교

+
+**이슈**: #10 follow-up (engine-bridge v3)
+**소요 시간**: ~95분 (HmEG 소스 survey + 3-tier 분리 디렉티브 반영 포함)
+**Context 사용량**: input ~165k / output ~30k tokens (Opus 4.6, 1M context, 동일 세션 누적)
+
+## 작업
+
+`docs/contracts/engine-bridge-v3.md` Sprint Contract 작성 후 D1/D6 구현:
+
+- `IAppManagerAccessor` 추상화 신설 — AppManager/ActiveDocument/ActiveViewport/Selection/Camera를 reflection 경계 뒤로 격리
+- `ReflectionAppManagerAccessor` — loaded assemblies에서 `Editor.AppManager.AppManager` 타입 + `Instance/Current/Default` static 프로퍼티 탐색, well-known 멤버 이름 후보 체인(Selection/SelectedObjects, Camera/ActiveCamera, Position/Eye, …)로 reflection lookup, vector는 `double[]` / `float[]` / `X/Y/Z` 세 가지 shape 모두 시도
+- `ReflectionEngineStateProvider` v2 stub 제거, 접근자 위임 구조로 재작성. HmEG 부재 환경(= CI)에서는 v2와 동일한 safe default 반환
+- `ReflectionEngineStateProviderTests` 9 테스트 추가 — FakeAccessor로 정상값/예외/null/HmEG 부재 폴백 커버. EgPlugin 테스트 5 → 14
+- 전체 suite green (100+ tests)
+
+## 라이브 검증 대기 (D7)
+
+reflection 멤버 후보 이름은 `hmeg-candidates.json` 기반 추측. SUT 라이브에서 `curl /scene /camera /selection` 응답 받아 실제 매칭 여부 확인 후 1~2회 보정 필요.
+
+## 전략 pivot — Reflection → HmEG 직접 참조
+
+사용자 지적: `Recordingtest.EgPlugin`은 이미 `HmEG.dll` + `Editor03.PluginInterface.dll`을 compile-time 참조 중이다 (`.csproj` 확인). 즉 reflection으로 멤버 추측할 필요가 없고, HmEG public 타입을 직접 호출하면 된다. 이식성(generic WPF)은 포기하지만 이 프로젝트는 EG-BIM Modeler 전용이므로 합리적 trade-off.
+
+이에 따라 사용자 동의 하에 HmEG 소스(`D:\GiteaAll\HmEngine\HmEG\HmEG`)를 read-only로 surveyed:
+
+확인된 공개 타입 (`<public-hmeg-api />` 마커 기준):
+- `ModelBase.Uid : Guid` — 영구 고유 ID, golden file 결정성의 핵심
+- `Space : ModelBase` — 문서 컨테이너. `Children`/`ItemsCount`/`Viewports`
+- `HmModel : ModelBase` — 형상 객체. `MouseDown/Enter/Leave` event (recorder hit-test 후보)
+- `HmEGViewport` (interface, namespace `HmEG`) — `CameraCore`, `Renderables`, `ViewportRectangle`
+- `IHmCamera` — Position/LookDirection/UpDirection (Fov는 PerspectiveCamera 캐스트 필요)
+- `ISelectable.IsSelected` — 노드별 (중앙 selection 리스트는 HmEG core에 없음 → Space walk + 필터)
+- `HmEG.IPlugin.View : EGViewport` — 플러그인이 로드 시 viewport 직접 주입받음
+
+산출: `docs/hmeg-api-survey.md` — 발견 내용, v3 구현 방향(`HmEgDirectStateProvider` + 람다 주입), SUT-side bridge 추가 엔드포인트(`/focus`, `/hit-test`, `/command`) 설계, 미해결 7개 질문(Q1~Q7) 큐.
+
+## 곁가지
+
+- 사용자 질문으로 "SUT 소스 협조 wishlist" 정리 — AutomationPeer 부착, AppManager.Instance 난독화 제외, read-only 상태 API, 명령 생명주기 이벤트 등 7항목을 대화에 남김. 필요 시 `docs/sut-cooperation-wishlist.md`로 문서화.
+- 미커밋 변경 존재 (engine-bridge v3 scaffold + contract + hmeg-api-survey.md + 본 마지막 단계의 3-tier 분리 작업). 다음 세션에서 분리 refactor 완료 후 통합 커밋 예정.
+
+## 아키텍처 디렉티브 — 3-tier 분리 (세션 후반)
+
+사용자 디렉티브 두 가지가 연속해서 들어왔다:
+1. "처음부터 WPF 일반인지 Modeler 테스트 자동화인지 코드 분리해놓아라"
+2. "대부분의 WPF는 HmEG(3D 그래픽 엔진)을 사용하고 있으니 이점도 고려해서 테스트 자동화를 설계해라"
+
+→ 즉 분리는 2-tier(generic vs SUT)가 아니라 **3-tier**:
+- **Generic** — 임의 WPF 응용
+- **HmEG-aware** — HmEG를 호스팅하는 임의 WPF 응용 (앱 미고정)
+- **App-specific** — 특정 응용 (현재 EG-BIM Modeler)
+
+의존 방향: App-specific → HmEG-aware → Generic. 역참조 금지.
+
+본 세션에서 한 일:
+- `CLAUDE.md §8.1` 신규 — 3-tier 규칙, 폴더 레이아웃, 강제 사항, 현재 모듈 분류표
+- `docs/contracts/generic-sut-split.md` 신규 — D1~D9 명세 (폴더/csproj 분할, 인터페이스 추출, HmegDirectStateProvider 골격, ArchitectureTests, sln 갱신)
+- `PLAN.md` — 본 refactor를 P0.5로 등록 (engine-bridge v3 진입 전 선결)
+- `PROGRESS.md` — In progress 에 해당 항목 추가
+
+본 contract는 다음 세션에서 Generator가 단일 작업 단위로 실행한다. **engine-bridge v3 코드 진입은 본 분리 완료 후**. 이유: `HmegDirectStateProvider`는 HmEG-aware 계층에 들어가야 다른 SUT에서 재사용 가능.

+# 2026-04-09 — Runner ↔ engine-bridge sidecar 통합
+
+**이슈**: #10 follow-up (engine-bridge v3 final integration)
+**소요 시간**: ~35분
+**Context 사용량**: input ~60k / output ~12k tokens (Opus 4.6)
+
+## 결과
+
+`TestRunner` 가 시나리오 재생 종료 직후 engine-bridge에서 `/scene` `/camera` `/selection` 스냅샷을 받아 `engine-state.received.json` 으로 기록하고, `<scenario>.engine-state.approved.json` 베이스라인과 별도 diff 패스를 돌린다. 이로써 golden-file 회귀 테스트의 **의미적(semantic) 차원**이 정식으로 파이프라인에 편입됐다.
+
+## 구현
+
+### 1. `IEngineStateSnapshotClient` (Generic tier)
+
+경로: `src/Recordingtest.Runner/IEngineStateSnapshotClient.cs`
+
+```csharp
+public interface IEngineStateSnapshotClient
+{
+    string? TryCapture();   // 실패 시 null, 예외 금지
+}
+```
+
+기본 구현 `HttpEngineStateSnapshotClient`: `http://localhost:38080` 을 기본 base URL로 쓰고 `/scene` `/camera` `/selection` 을 각각 GET한 뒤 세 응답을 하나의 JSON 객체로 합친다:
+
+```json
+{"scene":{...},"camera":{...},"selection":{...}}
+```
+
+고정 순서(scene → camera → selection)로 diff 친화적. 타임아웃 기본 2초. `HttpClient` 소유권 지원 (외부 주입 가능).
+
+Runner는 **Generic tier** 라서 HmEG 응답 shape를 모르고 raw JSON 문자열만 전달한다. 응답 해석 / 정규화는 하위 Normalizer가 담당.
+
+### 2. `TestRunner.RunAll(..., IEngineStateSnapshotClient? sidecarClient = null)`
+
+- 새 옵셔널 파라미터. null이면 기존 동작(sidecar skip).
+- `engine.Run` 직후 `CaptureAndDiffSidecar` 호출. 순서 중요: 재생이 끝났지만 host/SUT가 아직 살아있을 때 상태를 찍어야 의미있는 스냅샷.
+- 캡처 분기:
+  - client null → `SidecarStatus = "skipped"`
+  - `TryCapture()` null / throw → `"unavailable"`
+  - 성공 → `engine-state.received.json` 기록
+- 베이스라인 조회:
+  - `<baselinesDir>/<scenario>.engine-state.approved.json`
+  - `<baselinesDir>/<scenario>.engine-state.json`
+  - 없으면 `"missing_baseline"` (첫 실행 때 정상)
+- 있으면 normalizer pass → differ pass → `"pass"` / `"fail"`
+- **sidecar diff가 fail이면 시나리오 전체 Status를 `"fail"`로 승격** (메인 result diff는 별도 pass)
+- 모든 실패는 catch로 감싸 `"error"` 로 떨어뜨리고 `Error` 필드 prefix `sidecar:`
+
+### 3. `ScenarioResult` 확장
+
+```csharp
+public bool   SidecarCaptured { get; set; }
+public int    SidecarHunks    { get; set; }
+public string SidecarStatus   { get; set; } = "skipped";
+```
+
+markdown 리포트 표에 Sidecar / Sidecar Hunks 컬럼 추가. JSON 리포트는 camelCase로 자동 직렬화.
+
+### 4. `Program.cs` CLI
+
+```
+--sidecar-url <url>   # 기본 http://localhost:38080
+--no-sidecar          # sidecar 비활성 (기존 동작)
+```
+
+기본값은 **sidecar 활성**. 브릿지 플러그인이 로드돼 있으면 자동으로 잡힌다. 로드 안 돼 있어도 `unavailable` 상태로 기록되고 main result 는 계속 평가되므로 CI 안전.
+
+### 5. 테스트 (Runner.Tests)
+
+6개 신규:
+
+1. `Sidecar_NullClient_SkippedStatus` — null 클라이언트는 "skipped"
+2. `Sidecar_ClientReturnsNull_UnavailableStatus` — 빈 응답은 "unavailable"
+3. `Sidecar_Throws_UnavailableStatus_MainStillPasses` — 예외 삼키고 main은 pass
+4. `Sidecar_Captured_NoBaseline_MissingBaseline_And_WritesReceivedFile` — 첫 실행 시 received만 쓰고 missing_baseline
+5. `Sidecar_Captured_BaselineIdentical_PassPass` — 베이스라인 일치 시 sidecar pass
+6. `Sidecar_Captured_BaselineDivergent_PromotesScenarioToFail` — 불일치 시 시나리오를 fail로 승격
+
+`FakeSidecarClient` 로 `string?` payload / throw 스위치 제어.
+
+**총 132 tests pass (126 → 132, +6).**
+
+## 다음 단계 (라이브 검증 + 정규화 규칙)
+
+### P1-A — 라이브 루프 검증
+
+```
+dotnet run --project src\Recordingtest.Runner -- ^
+  --scenarios scenarios ^
+  --baselines baselines ^
+  --out artifacts\runner-out
+```
+
+기대:
+1. 첫 실행 → sidecar 상태 `missing_baseline`, `artifacts\runner-out\<scenario>\engine-state.received.json` 생성
+2. 사용자가 파일을 베이스라인 폴더로 복사(approve) → `<scenario>.engine-state.approved.json`
+3. 재실행 → sidecar 상태 `pass`
+
+### P1-B — normalizer sidecar 규칙
+
+현재는 identity normalize라서 float 경미한 차이나 selected_ids 순서 흔들림으로 false fail 날 수 있음. 필요 규칙:
+
+- **float epsilon** — camera eye/target 좌표. 이미 있는 `float_epsilon` 규칙을 sidecar profile에 등록
+- **selected_ids 정렬** — 선택 순서에 불변
+- **document_path 마스킹** — 경로 내 사용자/임시 디렉터리 정규화
+- **scene.object_count 절대 비교** (float 아닌 정수)
+
+Normalizer profile `engine-state` 신규 작성 후 `--profile` 로 전달하거나 Runner가 sidecar에 한해 다른 profile을 쓰도록 확장.

+# 2026-04-10 — camera-restore (Sprint Contract + Implementation)
+
+## Summary
+
+Implemented camera state capture at recording start and restore at playback start via the engine-bridge HTTP sidecar. Replays are now viewport-position-independent.
+
+## Changes

+- `docs/contracts/camera-restore.md` — Sprint Contract with 10 DoD items
+
+### Modified files

+| `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/ChainedEngineStateProvider.cs` | `SetCamera` delegates to primary only |
+| `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/BridgeHttpServer.cs` | Reads POST body (`StreamReader`) before calling `Route` |
+| `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/StateRouter.cs` | Added `Route(string method, string path, string body)` + `POST /camera/restore` + `ReadVecFromJson` helper; backwards-compat `Route(string path)` overload |

+| `src/Hmeg/Recordingtest.Hmeg.Bridge.Client/HmEgHttpSnapshot.cs` | Added `RestoreCamera(eye,target,up,fov)` POST method + `BuildCameraJson` helper |
+| `src/Recordingtest.Recorder/Scenario.cs` | Added `RecordedCameraSnapshot` class + `CameraSnapshot?` field on `Scenario` |
+| `src/Recordingtest.Recorder/Program.cs` | Added `--sidecar-url` CLI arg; `TryCaptureCamera(url)` internal helper (GET /camera, 2s timeout); stores snapshot in scenario |
+| `src/Recordingtest.Player/Model/Scenario.cs` | Added `ScenarioCameraSnapshot` class + `CameraSnapshot?` field |
+| `src/Recordingtest.Player/IPlayerHost.cs` | Added `TryRestoreCamera(eye,target,up,fov)` with default `return false` implementation |
+| `src/Recordingtest.Player/PlayerEngine.cs` | Calls `host.TryRestoreCamera(...)` before first step when `scenario.CameraSnapshot != null` |
+| `src/Recordingtest.Player/UiaPlayerHost.cs` | Optional `sidecarUrl` ctor param; `TryRestoreCamera` POSTs to `/camera/restore` |
+| `tests/Recordingtest.Player.Tests/FakePlayerHost.cs` | `TryRestoreCamera` override + `CameraRestoreCalls` tracking |
+| `tests/Recordingtest.Player.Tests/PlayerEngineTests.cs` | +5 camera tests (no-snapshot-skip, correct-values, false-return-continues, YAML parse, YAML null) |
+| `tests/Recordingtest.Recorder.Tests/RecorderTests.cs` | +3 camera tests (unreachable-null, roundtrip, null-field) |
+| Various test fake providers | Added `SetCamera` no-op to satisfy updated interface |
+
+## Test counts
+132 → **149** tests, all green.
+
+## Design decisions
+
+- `SetCamera` is write-only (no return); failures are silently swallowed — the SUT must never crash due to a record tool.
+- `WriteVec3` uses `ctor(double,double,double)` or `ctor(float,float,float)` reflection to construct WPF/HmEG vector types without a compile-time reference.
+- Camera write must be dispatched to WPF UI thread: `HmEgBridgePlugin` captures `Application.Current.Dispatcher.Invoke` at construction time and passes it as `Action<Action>`.
+- Legacy scenarios (no `camera_snapshot`) work unchanged — field is nullable, engine skips restore when null.
+- `UiaPlayerHost` creates a fresh `HttpClient` per `TryRestoreCamera` call (short-lived; no pooling needed at this stage).

+
+### 4. `HmEGViewport` (interface) — 뷰포트 공개 인터페이스
+경로: `Interface\IHmEGViewport.cs` (namespace `HmEG`)
+
+| 멤버 | 타입 | 비고 |
+|---|---|---|
+| `CameraCore` | `CameraCore` (`Model\Camera\CameraCore.cs`) | **카메라 진입점** |
+| `Renderables` | `IEnumerable<SceneNode>` | 3D 씬 그래프 루트 노드 enumerable |

+| `CreateViewMatrix(HmMatrix3D)` | method | |
+| `CreateProjectionMatrix(double aspectRatio)` | method | fov는 별도 추출 (PerspectiveCamera에) |
+
+> **주의**: `IHmCamera`에는 `Fov`/`FieldOfView`가 없다. `PerspectiveCamera : ProjectionCamera : CameraCore` 쪽에 있을 것으로 추정. v3 작성 시 `CameraCore` → `PerspectiveCamera` cast로 fov를 꺼낸다.
+
+### 6. `ISelectable` — 노드 선택 상태
+경로: `Interface\Interfaces.cs:235`
+
+```csharp
+public interface ISelectable
+{
+    bool IsSelected { get; set; }
+}
+```
+
+**중앙 집중 selection 리스트는 HmEG core에 없음.** SelectedIds를 얻으려면 Space 트리를 walk하면서 `ISelectable.IsSelected == true`인 노드를 모아야 한다. 또는 SUT 측 AppManager가 selection 리스트를 따로 들고 있을 수 있음 — **확인 필요**.
+
+### 7. `HmSceneNode : MaterialGeometryNode, IDynamicReflectable, ISelectable`
+경로: `Model\Scene\HmSceneNode.cs`
+
+씬 그래프의 실제 렌더링 노드. `IsSelected`를 가짐. `Renderables`에서 흘러나옴.
+
+### 8. `HmEG.IPlugin` (interface)
+경로: `PlugIns\IPlugin.cs`
+
+```csharp
+public interface IPlugin
+{
+    string Name { get; }
+    EGViewport View { get; set; }       // ← 플러그인에 직접 주입되는 뷰포트
+    bool RethrowException { get; set; }
+    object Run(params object[] args);
+}
+```
+
+**중요**: HmEG가 플러그인을 로드할 때 `View`를 직접 set 해준다. 즉 플러그인은 따로 Space/AppManager를 찾아갈 필요 없이 **`this.View`로 즉시 뷰포트에 도달**한다. 거기서 `CameraCore`, `Renderables` (씬 노드 enumerable) 모두 접근 가능. `Renderables`를 walk하면서 `ISelectable.IsSelected`로 선택된 노드 추출.
+
+> 본 저장소의 `HmEgBridgePlugin`은 `EditorPlugin` (SUT-side `Editor03.PluginInterface`) 베이스를 쓴다. `EditorPlugin`이 내부적으로 `HmEG.IPlugin.View`를 set 해주는지, 아니면 다른 경로(예: `AppManager`)를 통해 Space에 접근하는지는 **`Editor03.PluginInterface.dll` 디컴파일 또는 SUT-side 소스가 있어야 확정 가능**.
+
+## 아직 모르는 것 (확인 대기)
+
+| | 항목 | 어디서 찾아야 하는가 |
+|---|---|---|
+| Q1 | "활성 Space" 진입점 — `EGViewport.Space`? `AppManager.Instance.ActiveSpace`? | `Editor03.PluginInterface` / SUT-side AppManager |
+| Q2 | "활성 Viewport" 가 여러 개일 때 어느 것이 active 인가 | 동일 |
+| Q3 | 중앙 selection 리스트 (예: `AppManager.Selection`) 또는 selection-changed 이벤트 | 동일 |
+| Q4 | 명령 (Command) 생명주기 이벤트 — `CommandStarted` / `CommandFinished` 같은 것 | 동일 (`Editor.AppManager.AppModeManager` 후보) |
+| Q5 | `PerspectiveCamera`에서 `FieldOfView` 정확한 프로퍼티 이름 | `Model\Camera\PerspectiveCamera.cs` (read-only로 한 번만 더 확인하면 됨) |
+| Q6 | 문서 파일 경로 — 저장 후의 `*.hmeg` 경로 보유처 | `Editor03.PluginInterface` 또는 `AppManager.ActiveDocument` |
+| Q7 | `EGViewport` 와 `HmEGViewport` 관계 — `EGViewport`가 후자를 구현? 아니면 별개 SUT-side 클래스? | `Editor03.PluginInterface` |
+
+## v3 구현 방향 (Direct Provider)
+
+```csharp
+// src/Recordingtest.EgPlugin/HmEgDirectStateProvider.cs
+public sealed class HmEgDirectStateProvider : IEngineStateProvider
+{
+    private readonly Func<HmEG.HmEGViewport?> _getViewport;  // plugin이 주입
+    private readonly Func<Space?> _getSpace;                  // 동일
+
+    public IReadOnlyList<string> GetSelectedIds()
+    {
+        var sp = _getSpace();
+        if (sp is null) return Array.Empty<string>();
+        var ids = new List<string>();
+        Walk(sp, ids);
+        return ids;
+        static void Walk(ModelBase node, List<string> ids)
+        {
+            if (node is ISelectable s && s.IsSelected) ids.Add(node.Uid.ToString());
+            if (node is Space space)
+                foreach (var child in space.Children) Walk(child, ids);
+        }
+    }
+
+    public CameraSnapshot GetCamera()
+    {
+        var vp = _getViewport();
+        if (vp is null) return Default;
+        var cam = vp.CameraCore;
+        // CameraCore → IHmCamera 캐스트, 또는 Position/Look/Up 직접 접근
+        // PerspectiveCamera 캐스트로 FOV
+        ...
+    }
+
+    public SceneSnapshot GetScene()
+    {
+        var sp = _getSpace();
+        return new SceneSnapshot(
+            sp?.ItemsCount ?? 0,
+            DocumentPathFromSomewhere());  // Q6
+    }
+
+    public bool GetRenderComplete() => true; // 후속 작업
+}
+```
+
+`_getViewport` / `_getSpace` 람다는 `HmEgBridgePlugin`이 자기 환경(`EditorPlugin`이 노출하는 진입점)에서 캡처해 넘긴다. 람다 형태로 두면 다음과 같은 이점이 있다:
+- 플러그인 base 클래스가 진입점을 어떻게 노출하는지가 바뀌어도 v3 provider는 영향 없음
+- 단위 테스트는 fake 람다를 넘겨서 검증
+
+## SUT-side bridge 추가 엔드포인트 (Gap I 우회)
+
+`BridgeHttpServer` / `StateRouter`에 추가:
+
+| 엔드포인트 | 응답 | 사용처 |
+|---|---|---|
+| `GET /focus` | `{"path": "...", "type": "...", "name": "..."}` | recorder가 key_down 시 polling. `Keyboard.FocusedElement` (WPF)를 Dispatcher 위에서 호출 |
+| `GET /hit-test?x=&y=` | `{"hit": "HmModel#guid", "type": "...", "name": "..."}` | recorder가 click 시 호출. Space/Renderables walk + `VisualTreeHelper.HitTest` + (있으면) HmEG의 pick API |
+| `GET /command` | `{"running": "BOX", "phase": "awaiting_first_corner"}` | player의 wait_for. Q4 이벤트 구독 결과 캐시 |
+
+이건 engine-bridge v3 본 contract와 별도 contract 권장 (`/contract sut-side-bridge`).
+
+## 다음 액션
+
+1. **engine-bridge-v3.md 계약 갱신** — reflection 항목 제거, 위 타입/멤버 이름으로 D2/D3/D4 고정
+2. **Q1~Q7 확인** — 사용자가 SUT-side(Editor03.PluginInterface 또는 AppManager) 소스/경로 알려주면 read-only로 1~2회 더 확인
+3. Q1/Q3 채워지면 `HmEgDirectStateProvider` 구현 + 플러그인 wire-up
+4. CI fallback — 기존 `ReflectionEngineStateProvider` + `IAppManagerAccessor`는 fake-friendly 형태로 유지 (HmEG 어셈블리 없는 단위 테스트 환경에서 빌드/테스트 가능해야 함)
+5. 라이브 검증 → curl 로 `/state` 확인 → 보정 → 커밋

+# HmEG → WebGPU 포팅 가능성 분석
+
+> 작성일: 2026-04-10  
+> 배경: HmEG(Helix Toolkit 변형, SharpDX, Compute Shader 집약) 엔진을 웹 브라우저에 이식하는 방안 검토
+
+---
+
+## 1. WPF 3D 엔진을 웹에 탑재하는 방법
+
+WPF는 Windows 전용 스택(Win32 HWND, DirectX COM, WPF 렌더링 루프)이므로 브라우저에 직접 탑재는 불가능하다.
+
+### 현실적 대안
+
+| 방법 | 난이도 | 설명 |
+|------|--------|------|
+| WebAssembly 포팅 | 매우 높음 | 렌더링 코어를 C++/Rust로 재작성 → WASM + WebGL/WebGPU 컴파일 |
+| 서버 스트리밍 | 중간 | 서버에서 앱 실행 → WebRTC/H.264로 스트리밍 → 브라우저는 뷰어만 |
+| 씬 데이터 REST API | 낮음 | 엔진 상태를 HTTP로 노출 → three.js/Babylon.js로 독립 렌더링 |
+| Blazor Hybrid | 중간 | WPF + WebView2 조합 (역방향, 앱 안에 웹 UI) |
+
+---
+
+## 2. WebGPU 선택 시 가능한 것들
+
+### WebGL2 대비 WebGPU의 핵심 추가 기능
+
+| 기능 | WebGL2 | WebGPU |
+|------|--------|--------|
+| Compute Shader | ❌ | ✅ `@compute` |
+| Indirect Draw | ❌ | ✅ `drawIndirect` |
+| Storage Buffer (SSBO) | 제한적 | ✅ 완전 지원 |
+| Multi-draw Indirect | ❌ | ✅ (extension) |
+| Timestamp Query | ❌ | ✅ |
+| Wave Intrinsics | ❌ | ⚠️ `subgroups` extension, 불안정 |
+
+### 브라우저 지원 현황 (2026-04 기준)
+
+| 브라우저 | 지원 |
+|---------|------|
+| Chrome 113+ | ✅ 기본 활성화 |
+| Edge 113+ | ✅ 기본 활성화 |
+| Firefox | ⚠️ Nightly 실험적 |
+| Safari | ⚠️ 기술 프리뷰 |
+
+엔터프라이즈 내부 도구라면 Chrome/Edge 고정으로 충분히 현실적이다.
+
+---
+
+## 3. HmEG 스택 분석 (SharpDX + Helix Toolkit 변형)
+
+```
+HmEG
+├── C# 코드 (비즈니스 로직, 씬 그래프)
+├── SharpDX (DirectX 11 C# 바인딩)
+├── Helix Toolkit 변형 (WPF 렌더링 루프)
+└── HLSL Compute Shaders (병렬 연산 핵심)
+```
+
+**핵심 문제**: SharpDX는 DirectX 11 COM API의 thin wrapper — WASM에서 DirectX COM을 호출할 방법이 없다.
+
+### C# → WASM 경로 (Blazor WebAssembly)
+
+| 컴포넌트 | Blazor WASM 이식성 |
+|---------|------------------|
+| 비즈니스 로직 C# | ✅ 거의 그대로 |
+| SharpDX 렌더링 | ❌ DirectX COM 불가 |
+| WPF UI 계층 | ❌ 완전 교체 필요 |
+| HLSL Compute Shader | ⚠️ WGSL 재작성 필요 |
+
+---
+
+## 4. HLSL → WGSL 셰이더 변환
+
+### 변환 파이프라인
+
+```
+HLSL → DXC --spirv → SPIR-V → naga/Tint → WGSL
+```
+
+- **naga** (Rust, wgpu 프로젝트) — 가장 성숙한 변환 도구
+- **Tint** (Google) — WGSL 레퍼런스 컴파일러
+
+### Compute Shader 1:1 대응 예시
+
+```hlsl
+// HLSL (SharpDX)
+[numthreads(64, 1, 1)]
+void CSMain(uint3 id : SV_DispatchThreadID,
+            uint  gi : SV_GroupIndex)
+{
+    groupshared float4 cache[64];
+    cache[gi] = inputBuffer[id.x];
+    GroupMemoryBarrierWithGroupSync();
+    outputBuffer[id.x] = cache[gi] * 2.0;
+}
+```
+
+```wgsl
+// WGSL (WebGPU)
+var<workgroup> cache: array<vec4f, 64>;
+
+@compute @workgroup_size(64, 1, 1)
+fn cs_main(@builtin(global_invocation_id) id: vec3u,
+           @builtin(local_invocation_index) gi: u32) {
+    cache[gi] = input[id.x];
+    workgroupBarrier();
+    output[id.x] = cache[gi] * 2.0;
+}
+```
+
+구조는 1:1 대응된다. 알고리즘 재설계가 아니라 문법 변환이다.
+
+### 주요 변환 난관
+
+- `SV_Position` vs `gl_Position` — 좌표계 Y축 반전 필요
+- `cbuffer` → `uniform block` 구조 재정렬
+- `groupshared`, `numthreads` Compute 확장 — WGSL에서 직접 지원
+- 행렬 규약 차이 (row-major vs column-major) — 암묵적 가정 수동 확인 필요
+
+---
+
+## 5. AI를 통한 코드 포팅 가능성
+
+### 컴포넌트별 AI 포팅률
+
+| 컴포넌트 | AI 포팅률 | 이유 |
+|---------|----------|------|
+| HLSL Compute → WGSL | **90%+** | 1:1 구조 매핑, 패턴 명확 |
+| HLSL Vertex/Pixel → WGSL | **95%+** | 가장 단순한 변환 |
+| SharpDX API → WebGPU (TS/Rust) | **85%** | API 문서 명확, 대응표 존재 |
+| 씬 그래프 / 지오메트리 C# → TS/Rust | **75%** | 로직 자체는 언어 무관 |
+| 렌더링 루프 / 파이프라인 재구성 | **60%** | 아키텍처 판단 필요 |
+| 최적화 로직 (배치, 컬링 등) | **50%** | 알고리즘은 번역, GPU 특성 차이 보정은 수동 |
+
+> **주의**: 최적화 로직 50%는 "절반만 작동한다"는 뜻이 아니다.  
+> 알고리즘 코드는 AI가 번역하고, GPU 튜닝 파라미터(워크그룹 크기 등)를 WebGPU 환경에서 재측정하는 작업이 수동이다.  
+> 최적화 알고리즘 자체는 100% 이식된다.
+
+### 실제 포팅 흐름
+
+```
+1단계 — AI 일괄 변환 (자동화 가능)
+  ├── 전체 .hlsl 파일 → WGSL 변환 (AI)
+  ├── SharpDX 초기화 코드 → WebGPU 초기화 (AI)
+  └── C# 수학/지오메트리 유틸 → wgpu-matrix (AI)
+
+2단계 — AI 지원 + 인간 검토
+  ├── 렌더링 파이프라인 재구성 (AI 초안 → 인간 검토)
+  ├── 좌표계/행렬 규약 맞춤 (AI 탐지 → 인간 확인)
+  └── 바인딩 그룹 레이아웃 설계 (AI 제안 → 인간 결정)
+
+3단계 — 인간 주도
+  ├── GPU 프로파일링 및 최적화 튜닝
+  └── 엣지 케이스 버그 수정
+```
+
+### 전체 공수 추정 (50,000줄 규모 가정)
+
+| 작업 | 비율 |
+|------|------|
+| AI 자동 변환 가능 | ~60-70% |
+| AI 초안 + 인간 검토 | ~20% |
+| 인간이 처음부터 재작성 | ~10-20% |
+
+---
+
+## 6. 나나이트 유사 기능 WebGPU 구현 가능성
+
+### 나나이트 핵심 기능별 WebGPU 가능 여부
+
+| 나나이트 기능 | WebGPU | 비고 |
+|-------------|--------|------|
+| 클러스터 기반 BVH | ✅ | Storage Buffer로 구현 |
+| GPU-side LOD 선택 | ✅ | Compute Shader로 완전 구현 |
+| Indirect Draw | ✅ | `drawIndirect` 지원 |
+| 소프트웨어 래스터라이저 | ⚠️ | Storage Texture 쓰기로 구현 가능, 성능 제한 |
+| **Mesh Shader** | ❌ | WebGPU 미지원 (2026 현재) |
+| Wave Intrinsics | ⚠️ | `subgroups` extension, 불안정 |
+| Visibility Buffer | ✅ | 완전 구현 가능 |
+
+**Mesh Shader 없이**: Compute + Indirect Draw 조합으로 알고리즘 동일, GPU 효율 15~30% 낮음.
+
+**BIM 모델러 용도**: 수백만 폴리곤 건축 모델 실시간 가시화 수준은 WebGPU + 나나이트 유사 구현으로 충분히 가능.
+
+---
+
+## 7. DirectX 12 기능 → WebGPU 전체 대응표
+
+### 렌더링 파이프라인
+

+| Placed Resources | — | ❌ |
+| Resource Aliasing | — | ❌ |
+| Tiled/Sparse Resources | — | ❌ |
+| Resource Barriers | 암묵적 자동 처리 | ⚠️ |
+
+### 고급 렌더링

+| FSR (upscaling) | Compute로 구현 가능 | ⚠️ |
+| Indirect Draw/Dispatch | `drawIndirect` | ✅ |
+| Timestamp Query | ✅ (약간 흐릿) | ✅ |
+
+### 커버리지 요약
+
+```
+DX12 기능 집합

+└─────────────────────────────────────────┘
+```
+
+**WebGPU ≈ DirectX 11.1 ~ 12 하위집합**
+
+### BIM 모델러 관점 실질 영향
+
+| 기능 | BIM 필요도 | WebGPU 대안 |
+|------|-----------|------------|
+| Ray Tracing | 선택적 | Screen Space 기법 |
+| Mesh Shader | 나나이트 성능 | Compute + Indirect 80% |
+| Sparse Resources | 초대형 텍스처 스트리밍 | 수동 Texture Atlas |
+| Multi-queue | 백그라운드 로딩 | Web Worker + Staging Buffer |

+
+## 8. 권장 포팅 아키텍처

+```
+
+또는 C++ 기반으로 재타깃:
+
+```
+HmEG C++ Core
+    ↓
+Dawn (C++ WebGPU 구현) 백엔드 추가
+    ↓
+Emscripten 컴파일 → WASM
+    ↓
+브라우저 (Chrome/Edge)
+```
+
+---
+
+## 결론
+
+- **단순 이식 불가**: WPF/SharpDX는 Windows 네이티브 스택, 브라우저 직접 탑재 불가
+- **WebGPU는 현실적 선택**: Compute Shader 집약적인 HmEG와 잘 맞음, DX11.1 수준 기능 커버
+- **AI 포팅 효과**: 셰이더·API 변환 60~70% 자동화 가능, 성능 튜닝은 수동
+- **나나이트 유사**: 알고리즘 80% 구현 가능, Mesh Shader 부재로 완전 동일 성능은 어려움
+- **BIM 용도**: 충분히 현실적, 건축 모델 수백만 폴리곤 실시간 가시화 가능
