+name: evaluator
+description: 완료된 모듈 또는 기능을 Sprint Contract 기준으로 채점한다. Generator와 독립적으로 동작 — 계약을 읽고 산출물을 검토하며, 각 DoD 항목을 pass/fail로 평가해 보고한다. Generator가 "완료"를 보고한 후, 작업이 머지되거나 PROGRESS.md에 완료로 표시되기 전에 사용한다.
+tools: Read, Grep, Glob, Bash
+model: sonnet

+
+당신은 **evaluator**다. 의도적으로 해당 기능을 만든 에이전트가 아니다. 독립적인 검증이 당신의 가치다.
+
+## 입력
+- `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.
+
+## 출력 형식
+
+```markdown
+# Evaluation — <이름>  (<YYYY-MM-DD HH:MM>)
+
+Verdict: **pass** | **fail**

 # CLAUDE.md — recordingtest

-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
-
-## 3. 아키텍처 구성요소(예정)
-
-| 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 |
-
-각 모듈은 독립 PoC → 통합 순서로 진행한다.
-
-## 4. 기술 스택 가이드
-
- **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)
-
-누락 시 저장이 차단된다.
-
-### 저장소
- Origin: https://gitea.hmac.kr/kimminsung/recordingtest
- 이슈 트래커: 동일 Gitea
- PR/커밋 메시지에 이슈 번호(#N) 참조
-
-### 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
- 의존성 추가는 사전에 사용자 확인
- 메모리 시스템(`~/.claude/projects/.../memory/`)에 프로젝트 진행 상태/전략 결정 보존
- 작업 종료 시 PROGRESS.md / PLAN.md 업데이트 + 히스토리 파일 작성 (3종 세트)
-
-## 8. 디렉터리 구조 (예정 — 셋업 시 확정)

- 단위 테스트 프레임워크 대체
-
-## 8.1 코드 계층 분리 (의무 규칙)
-
-본 도구는 **EG-BIM Modeler 외에도 다양한 WPF 응용**을 회귀 자동화 대상으로 삼는다. 또한 사용자 WPF 응용군의 **대다수가 자체 3D 엔진 `HmEG`를 공유**한다. 따라서 코드는 다음 **3개 계층** 중 하나에 명시적으로 속한다.
-
-| 계층 | 의미 | 의존 가능 | 폴더/네이밍 |
+| 계층 | 참조 가능 | 위치 | 네임스페이스 |
 |---|---|---|---|

+## 설계 규칙

-### 강제 사항
+- **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**
+- **SUT in-process 코드는 WPF UI thread에서 실행**
+- 베이스라인 명명: `*.approved.*` / `*.received.*`
+- 실패 아티팩트: 스크린샷 + UIA 트리 + sidecar JSON + diff를 한 폴더에

-1. **Generic 코드는 어떤 SUT 어셈블리도 참조하지 않는다.** `HmEG.dll`도 안 됨.
-2. **HmEG-aware 코드는 `HmEG.dll`만 참조**한다. 특정 앱(`Editor03.PluginInterface.dll` 등)은 참조 금지.
-3. **App-specific 코드만이 자기 앱의 어셈블리를 참조**한다.
-4. **확장 지점은 항상 한 계층 아래에 인터페이스로 둔다.** 예:
-   - `IEngineStateProvider` (Generic) ← `HmegEngineStateProvider` (HmEG-aware) ← `EgBimAppManagerAdapter` (App-specific 진입점만 제공)
-   - `ITargetResolver` (Generic) ← `HmegSceneNodeTargetResolver` (HmEG-aware) ← ...
-5. **시나리오 포맷, 베이스라인 포맷, 정규화 규칙은 Generic.** HmEG/앱 특화 정규화 규칙이 필요하면 그 계층에서 plugin 식으로 등록한다.
-6. **새 SUT를 추가할 때 HmEG-aware 코드는 재사용**한다. 새로 작성하지 말 것. 앱마다 다른 부분만 App-specific에 둔다 (보통: 플러그인 호스트 진입점 + 명령 lifecycle 이벤트 어댑터).

+
+Verdict: **pass**
+
+| # | DoD item | Score | Evidence |

+| D1 | `IEngineStateProvider` has `SetCamera(CameraSnapshot)`. `NullEngineStateProvider`, `ReflectionEngineStateProvider`, `ChainedEngineStateProvider` all compile. | pass | `src/Recordingtest.Bridge.Abstractions/IEngineStateProvider.cs` line 23 (`void SetCamera(CameraSnapshot snapshot)`); `NullEngineStateProvider.SetCamera` line 43 (no-op); `ReflectionEngineStateProvider.SetCamera` in `src/Sut/EgBim/.../IEngineStateProvider.cs` line 84 (no-op); `ChainedEngineStateProvider.SetCamera` line 56 (delegates to primary). All pass `dotnet test` build. |
+| D2 | `HmegDirectStateProvider.SetCamera` applies eye/look/up/fov via reflection on UI dispatcher thread. | pass | `src/Hmeg/Recordingtest.Hmeg.Bridge/HmegDirectStateProvider.cs` lines 167–201: `SetCamera` computes lookDir from target-eye, calls `WriteVec3`/`WriteDouble` via reflection. Dispatches via `_uiDispatch` when not null (lines 192–195). `HmEgBridgePlugin` wires `Application.Current.Dispatcher.Invoke` at line 116. |
+| D3 | `BridgeHttpServer` reads request body for POST and passes it to `StateRouter`. | pass | `src/Sut/EgBim/.../BridgeHttpServer.cs` lines 46–56: reads `ctx.Request.InputStream` when `HasEntityBody`; passes `requestBody` to `_router.Route(method, path, requestBody)` at line 57. |
+| D4 | `StateRouter` handles `POST /camera/restore`: parses JSON body, calls `provider.SetCamera(...)`. Returns `{"ok":true}` on success, `{"error":"..."}` on failure. | partial | `src/Sut/EgBim/.../StateRouter.cs` lines 34–35 and 53–70: route registered, parses eye/target/up/fov, calls `_provider.SetCamera(...)`, returns `{"ok":true}`. On failure returns `{"ok":false,"error":"..."}` (line 68), not the bare `{"error":"..."}` specified in the contract. Minor extra field present; functionally compatible. |
+| D5 | `HmEgHttpSnapshot.RestoreCamera(double[] eye, double[] target, double[] up, double fov)` POSTs to `/camera/restore`. | pass | `src/Hmeg/Recordingtest.Hmeg.Bridge.Client/HmEgHttpSnapshot.cs` lines 94–115: method exists, POSTs to `_baseUrl + "/camera/restore"` with JSON body built by `BuildCameraJson`. |
+| D6 | Recorder `Scenario` model has `CameraSnapshot?` field (YAML: `camera_snapshot`). Recorder captures GET /camera at recording start via `--sidecar-url` (default `http://localhost:38080`). | pass | `src/Recordingtest.Recorder/Scenario.cs` line 13: `public RecordedCameraSnapshot? CameraSnapshot`. `Program.cs` line 118: `TryCaptureCamera(args.SidecarUrl)` called before recording. `ParseArgs` line 61 defaults `sidecarUrl` to `"http://localhost:38080"`. `ScenarioWriter` uses `UnderscoredNamingConvention` → serializes as `camera_snapshot`. |
+| D7 | Player `Scenario` model has `CameraSnapshot?` field. `IPlayerHost.TryRestoreCamera(...)` defaults to `return false`. `PlayerEngine.Run()` calls it when snapshot not null, logs result. | pass | `src/Recordingtest.Player/Model/Scenario.cs` line 10: `public ScenarioCameraSnapshot?

Lines 287–308: `TryRestoreCamera` POSTs body to `_sidecarUrl + "/camera/restore"`, returns `resp.IsSuccessStatusCode`, catches all exceptions and returns false. |

+
+## 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`. |
+| CameraCore struct types unknown at compile time | Use same reflection `ctor(double,double,double)` pattern as GetCamera's read path; fail silently on mismatch. |
+| Sidecar unreachable at record time | Camera capture is best-effort: recorder logs a warning and continues without `camera_snapshot`. |
+| Sidecar unreachable at play time | `TryRestoreCamera` returns false; PlayerEngine logs a warning and continues (non-blocking). |
+| Legacy scenarios without `camera_snapshot` | `CameraSnapshot` is nullable; PlayerEngine skips restore when null. Fully backwards-compatible. |

+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

+# 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
+
+### New files
+- `docs/contracts/camera-restore.md` — Sprint Contract with 10 DoD items
+
+### Modified files
+
+| File | Change |
+|------|--------|
+| `src/Recordingtest.Bridge.Abstractions/IEngineStateProvider.cs` | Added `SetCamera(CameraSnapshot)` to interface + `NullEngineStateProvider` no-op |
+| `src/Hmeg/Recordingtest.Hmeg.Bridge/HmegDirectStateProvider.cs` | Added `SetCamera` via reflection (`WriteVec3`/`WriteDouble`), optional `uiDispatch: Action<Action>` ctor param |
+| `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/IEngineStateProvider.cs` | `ReflectionEngineStateProvider.SetCamera` no-op |
+| `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/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/HmEgBridgePlugin.cs` | Passes `Application.Current.Dispatcher.Invoke` as `uiDispatch` to `HmegDirectStateProvider` |
+| `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).

+# 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)

+
+3단계 — 인간 주도

+```
+
+### 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.

+- **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

minsung	e28a029704	runner: engine-bridge sidecar integration (#10 ) At the end of each scenario playback the runner now fetches a state snapshot from the engine-bridge HTTP server and diffs it against an approved engine-state baseline. This closes the engine-bridge v3 loop and adds a semantic-state axis to the golden-file regression strategy — diffs can now catch "camera moved" or "wrong selection after command" even when the main saved-file diff still passes. New: src/Recordingtest.Runner/IEngineStateSnapshotClient.cs IEngineStateSnapshotClient.TryCapture() -> string? (never throws) HttpEngineStateSnapshotClient — GETs /scene /camera /selection off a base URL (default http://localhost:38080), composes them into { "scene": {...}, "camera": {...}, "selection": {...} } with stable ordering so the downstream differ stays friendly. Runner is Generic tier, so this client carries zero HmEG knowledge; it forwards raw JSON strings. TestRunner.RunAll now takes an optional IEngineStateSnapshotClient. After engine.Run() completes, CaptureAndDiffSidecar(): - null client -> SidecarStatus = "skipped" - TryCapture null/throw -> "unavailable" (main result still evaluated) - success -> writes engine-state.received.json - baseline found -> normalize + diff + "pass"/"fail" - baseline missing -> "missing_baseline" (first run convention) A sidecar "fail" promotes the overall scenario Status to "fail" so exit code reflects semantic divergence even when the save-file diff agrees. ScenarioResult: SidecarCaptured / SidecarHunks / SidecarStatus. Markdown report grows Sidecar + Sidecar Hunks columns; JSON report picks up the new fields automatically via camelCase serialization. Program.cs: --sidecar-url <url> (default localhost:38080) and --no-sidecar. Default behaviour is sidecar-on so that a loaded bridge plugin is picked up automatically; when the plugin is not deployed the client silently reports "unavailable" and CI still runs. Baseline lookup (new): <baselinesDir>/<scenario>.engine-state.approved.json <baselinesDir>/<scenario>.engine-state.json Tests (Recordingtest.Runner.Tests, +6): - Sidecar_NullClient_SkippedStatus - Sidecar_ClientReturnsNull_UnavailableStatus - Sidecar_Throws_UnavailableStatus_MainStillPasses - Sidecar_Captured_NoBaseline_MissingBaseline_And_WritesReceivedFile - Sidecar_Captured_BaselineIdentical_PassPass - Sidecar_Captured_BaselineDivergent_PromotesScenarioToFail Full suite 126 -> 132, 0 failures. Follow-ups (PLAN.md): - Live loop: first run writes received, user approves, rerun passes. - Normalizer profile for engine-state (float epsilon for camera coords, selected_ids sort, document_path masking). Currently runs through the default profile as identity, so false fails are possible for sensitive camera moves until this lands. Ref: #10 engine-bridge v3 final integration.

minsung	062a285462	engine-bridge v3 live: /scene /camera /selection all real (#10 ) Live end-to-end verification against EG-BIM Modeler succeeded on the second attempt: /health -> {"status":"ok","port":38080} /scene -> {"object_count":4,"document_path":"NewSpace0"} /camera -> {"eye":[192.97,-328.52,170.72], "target":[33.03,-72.61,10.78], "up":[0,0,1],"fov":45} /selection -> {"selected_ids":["ac0380a2-...","d9a287ee-..."]} 1st attempt returned default-zero camera. Root cause: the viewport lambda used EditorPlugin.View, which is only populated when the plugin is actually Run() by a user trigger; our bridge plugin just boots an HTTP server from its constructor and never runs a command, so View stayed null. Space access worked because RootSpace goes through AppManager, which is populated for the whole app. Fix (HmEgBridgePlugin.BuildProvider): Before: viewportProvider = () => View; After: viewportProvider = () => { var vm = AppManager?.ViewportManager; if (vm is null) return null; return vm.FocusedViewport ?? vm.Viewports.FirstOrDefault(); }; Confirmed against read-only view of HmEGApplicationManagementLibrary/SubManager/ViewportManager.cs which exposes FocusedViewport and Viewports. EGViewport : HmEGViewport so the lambda matches the Func<HmEGViewport?> contract directly. Plus: scripts/deploy-egbim-plugin.bat for one-click deploy. Checks for a running SUT, builds Debug, purges the legacy Recordingtest.EgPlugin folder, cleans the destination, copies 3 DLLs (+ PDBs) into EG-BIM Modeler/Plugins/Recordingtest.Sut.EgBim.PluginHost/ and prints the curl commands for verification. HmEG.dll and the Editor*.dll assemblies are deliberately NOT copied — the SUT already supplies them. PROGRESS.md: engine-bridge v3 row finalized; the long-running "라이브 검증 대기" item is done. PLAN.md P1 advances to the Runner <-> sidecar integration (snapshot /scene /camera /selection at scenario end and include in the golden baseline). Follow-up (noted in history): document_path returned "NewSpace0" for an unsaved scratch document — need to retest with a saved .hmeg file to confirm the real FileManager.CurrentFile round-trip. Ref: #10 follow-up, engine-bridge-v3 contract DoD D7 satisfied. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-09 11:38:51 +09:00
