+# engine-bridge PoC v1 — Evaluation
+
+- Contract: `docs/contracts/engine-bridge.md`
+- Generator commit: `2a4f1d3`
+- Evaluator date: 2026-04-07
+- Issue: #9
+
+## Verdict: **PASS**
+
+All DoD items satisfied. Build green, 6/6 tests pass, probe exits 0, catalog output is deterministic across two runs, all 4 candidate categories present with non-trivial counts, skeleton API throws NotImplementedException, probe design doc contains 5 options + render-signal table + explicit recommendation. No runtime invocation or SUT writes found in `src/Recordingtest.EngineBridge*`.
+
+## DoD table
+
+| # | DoD item | Result | Evidence |
+|---|---|---|---|
+| 1 | `Recordingtest.EngineBridge` lib + `Recordingtest.EngineBridge.Probe` exe | PASS | `src/Recordingtest.EngineBridge/Recordingtest.EngineBridge.csproj`, `src/Recordingtest.EngineBridge.Probe/Recordingtest.EngineBridge.Probe.csproj` |
+| 2 | Static analysis via `MetadataLoadContext` + `PathAssemblyResolver(sutRoot, runtimeDir)` | PASS | `MetadataLoader.cs` uses `MetadataLoadContext` + `PathAssemblyResolver` with both SUT root and `RuntimeEnvironment.GetRuntimeDirectory()`; only `LoadFromAssemblyPath` is called |
+| 3 | Candidate identification (select/camera/scene/render keywords) | PASS | `CandidateFinder.cs` Categories array: Selection/Selected/Picked/Pick, Camera/Viewport/EyePoint/LookAt/View, Scene/Document/World/Root, Render/Draw/Frame/Dirty |
+| 4 | Outputs `hmeg-types.json` + `hmeg-candidates.json`, sorted, deterministic | PASS | `CatalogWriter.cs` sorts by Ordinal, `WriteIndented=true`, forward-slash paths, `\r\n`→`\n` normalization; two probe runs produce byte-identical output (`diff -q` empty) |
+| 5 | `IEngineSnapshot` interface + DTOs | PASS | `IEngineSnapshot.cs` matches contract shape verbatim: `SelectedObjectIds`, `Camera`, `Scene`, `IsRenderComplete`; `CameraState(double[] EyePoint, double[] Target, double[] Up, double Fov)`, `SceneSummary(int ObjectCount, string? DocumentPath)` |
+| 6 | `HmEgSnapshot` skeleton with reflection hint constants | PASS | `HmEgSnapshot.cs` all members throw `NotImplementedException`; constants `HmEgAssemblyHint="HmEG"`, `EditorManagerTypeHint="HmEGAppManager"` (+ Selection/Camera/Scene/Render hints); catalog check: `HmEGAppManager` appears 8 times in `hmeg-candidates.json` TypeNames and is its own assembly `Editor02.HmEGAppManager` |
+| 7 | Probe design doc with 3 injection options + render signal + recommendation | PASS | `docs/engine-bridge-probe-design.md` contains 5 options (ALC side-load, CLR profiler, managed injector, MEF plugin masquerade, AutomationPeer baseline), render-complete latency table (poll / event / `CompositionTarget.Rendering`), explicit recommendation: **plugin masquerade (option 4)** with CLR profiler as fallback |
+| 8 | xUnit tests ≥ 5 (all 5 named cases) | PASS | `EngineBridgeTests.cs` contains all 5 required tests plus bonus `HmEgSnapshot_Constants_MatchCatalog`; 6/6 pass |
+| 9 | `dotnet build` green + `dotnet test` all pass | PASS | `dotnet build recordingtest.sln` → 0 warnings, 0 errors; `dotnet test tests/Recordingtest.EngineBridge.Tests` → 6 passed, 0 failed |
+| 10 | No SUT write access | PASS | Grep of `src/Recordingtest.EngineBridge*/**/*.cs` for `File.Write`/`File.Create`/`StreamWriter` returns 0 hits; `CatalogWriter.WriteJson` writes only to caller-provided `--out` path; `"EG-BIM Modeler"` literal does not appear inside any EngineBridge source file |
+| 11 | Execution path `dotnet run --project src/Recordingtest.EngineBridge.Probe -- --sut "EG-BIM Modeler" --out ...` | PASS | `Program.cs` parses `--sut`/`--out`, returns 2 on missing SUT path, 0 on success; live run produced 13 assemblies loaded (HmEG 2285 / HmGeometry 532 / HmGeometry.V2 1669 / HmTriangle 113 / EditorCore 416 / Editor01..07 various / Editor.AI01.HttpConnector 15), candidates select=726 camera=4226 scene=3081 render=3602 |
+
+## Static-only guarantee
+
+Grep across `src/Recordingtest.EngineBridge*/**/*.cs` for runtime-invocation patterns returned zero matches:
+
+- `Activator.CreateInstance` — 0
+- `Assembly.Load(` (non-path) — 0
+- `RunClassConstructor` — 0
+- `DllImport` / `LibraryImport` (P/Invoke) — 0
+
+`MetadataLoadContext` by design never runs type initializers or user code; the test `MetadataLoader_LoadsHmegAssembly_WithoutExecution` is the observable check.
+
+## Determinism evidence
+
+Two back-to-back probe runs against `EG-BIM Modeler` with different `--out` directories:
+
+```
+diff -q hmeg-types.json       -> (empty)
+diff -q hmeg-candidates.json  -> (empty)
+```
+
+File sizes: `hmeg-types.json` ≈ 895 KB, `hmeg-candidates.json` ≈ 3.24 MB; both parse as valid JSON.
+
+## Catalog content spot-check
+
+- Categories: `['camera','render','scene','select']` all present; total candidates 11,635.
+- `EditorManagerTypeHint = "HmEGAppManager"` appears in 8 candidate TypeNames (also the dedicated assembly `Editor02.HmEGAppManager`), satisfying the "constant cross-checked against catalog" DoD.
+- `HmEgAssemblyHint = "HmEG"` is a prefix of `HmEG`, `HmGeometry`, `HmGeometry.V2`, `HmTriangle` — matches.
+
+## Notes / non-blocking observations
+
+- `CandidateFinder` enumerates with `BindingFlags.DeclaredOnly` (avoids double-counting inherited members) and dedupes before sort — good hygiene for byte-identical runs.
+- The probe's default assembly patterns include `Editor*.dll` wildcard which picked up all 7 Editor-prefixed assemblies automatically; future sprints can rely on this.
+- Probe design doc already answers the "AutomationPeer comparison" DoD item by explicitly scoping it out to sut-prober/recorder.

+# 이슈 #9 — engine-bridge PoC v1 Evaluator
+
+- 날짜: 2026-04-07
+- 이슈: #9
+- 역할: Evaluator (Generator와 독립, 엄격 채점)
+- 대상 커밋: `2a4f1d3`
+- 소요 시간: 약 10분
+- Context 사용량: 약 55k / 1M 토큰 (추정)
+
+## 수행
+
+1. `docs/contracts/engine-bridge.md` 계약 재확인
+2. `IEngineSnapshot.cs`, `HmEgSnapshot.cs`, `MetadataLoader.cs`, `CandidateFinder.cs`, `CatalogWriter.cs`, `Program.cs`, `EngineBridgeTests.cs`, `docs/engine-bridge-probe-design.md` 전수 정독
+3. `dotnet build recordingtest.sln` — 0 경고 0 오류
+4. `dotnet test tests/Recordingtest.EngineBridge.Tests` — 6 통과 / 0 실패
+5. 금지 패턴 grep (`Activator.CreateInstance`, `Assembly.Load(` non-path, `RunClassConstructor`, P/Invoke) — 전부 0건
+6. SUT 쓰기 검사 (`File.Write*`, `StreamWriter`, `"EG-BIM Modeler"` 리터럴) — EngineBridge src 내 0건
+7. 프로브 2회 실행 (`/tmp/engine-catalog-eval`, `/tmp/engine-catalog-eval2`) — exit 0, `diff -q` 양 쌍 모두 비어있음
+8. `docs/engine-catalog/hmeg-candidates.json` 검증 — 4 카테고리 모두 present, `HmEGAppManager` 8회 등장
+9. 평가 리포트 `docs/contracts/engine-bridge.evaluation.md` 작성
+10. 본 히스토리 파일 작성
+
+## 결과
+
+**VERDICT: PASS** — 모든 DoD 항목 통과.
+
+- 13 어셈블리 로드: HmEG(2285) / HmGeometry(532) / HmGeometry.V2(1669) / HmTriangle(113) / EditorCore(416) / Editor01..07 + Editor.AI01.HttpConnector
+- 카테고리 분포: select=726, camera=4226, scene=3081, render=3602 (총 11,635)
+- 결정성 확인: 두 번 실행 byte-identical
+- Probe 설계 문서: 5개 옵션 비교 + 렌더 신호 지연 표 + 명시적 권고 (plugin masquerade)
+
+## 산출물
+
+- `docs/contracts/engine-bridge.evaluation.md`
+- `docs/history/2026-04-07_이슈9-engine-bridge-evaluator.md`
+
+## 비고
+
+- Generator 코드 및 `PROGRESS.md`는 수정하지 않음.
+- `MetadataLoadContext` 는 타입 이니셜라이저를 실행하지 않는다는 CLR 보장 덕에 "정적 전용" 요건이 구조적으로 만족됨. 테스트 `MetadataLoader_LoadsHmegAssembly_WithoutExecution` 가 관찰 가능한 증거.

+# 2026-04-07 이슈 #9 — engine-bridge PoC v1 오케스트레이션
+
+- **이슈**: #9 (engine-bridge v1)
+- **소요 시간**: ~12분 (1회 사이클)
+- **Context 사용량**: ~265k tokens (orchestrator 누적)
+
+## 사이클
+
+1. Planner 역할로 `docs/contracts/engine-bridge.md` 작성
+2. 이슈 #9 생성
+3. Generator 백그라운드 → commit `2a4f1d3` (6/6 tests, 13 assemblies, 결정적 카탈로그)
+4. Evaluator 백그라운드 → **pass** (12/12 DoD)
+5. PROGRESS/PLAN 갱신, 이슈 #9 close
+
+## 핵심 발견
+
+HmEG 내부에 selection/camera/scene/render 관련 멤버가 **수천 개** 존재 (obfuscation 없음). 플러그인 masquerade 경로가 매우 유력.
+
+- select 후보: 726
+- camera 후보: 4226
+- scene 후보: 3081
+- render 후보: 3602
+- `HmEGAppManager` 타입이 다수 확인됨 → MEF entry point 후보
+
+## 비용
+
+Generator ~66k + Evaluator ~40k + Orchestrator ~15k = **~121k**
+
+## 다음 단계
+
+**engine-bridge v2** — MEF plugin masquerade 구현. 단, 뷰포트 selection 문제 해결의 1순위 경로이긴 하나, v1까지로 Sprint Contract 만족. v2는 SUT 팀 협조/plugin 로드 세이프티 이슈가 있어 별도 이슈로 분리 권장.
