BREAKING: 3-tier split step 2 + engine-bridge v3 EgBim lambdas wired

Completes the Generic / HmEG-aware / App-specific separation started in
f6b6e74. The legacy EgPlugin / EngineBridge / EngineBridge.Client /
EngineBridge.Probe modules are moved into their proper tiers, namespaces
and csproj/sln entries are renamed, and the HmegDirectStateProvider
lambdas are finally populated with real handles from the EgBim plugin
host. A new Recordingtest.Architecture.Tests project enforces the tier
rule at build time.

Moves (git mv + csproj/RootNamespace/AssemblyName rename + sln):

  src/Recordingtest.EgPlugin
    -> src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost
  src/Recordingtest.EngineBridge
    -> src/Hmeg/Recordingtest.Hmeg.Catalog
  src/Recordingtest.EngineBridge.Client
    -> src/Hmeg/Recordingtest.Hmeg.Bridge.Client
  src/Recordingtest.EngineBridge.Probe
    -> src/Hmeg/Recordingtest.Hmeg.Catalog.Probe

  tests/Recordingtest.EgPlugin.Tests
    -> tests/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost.Tests
  tests/Recordingtest.EngineBridge.Tests
    -> tests/Hmeg/Recordingtest.Hmeg.Catalog.Tests
  tests/Recordingtest.EngineBridge.IntegrationTests
    -> tests/Hmeg/Recordingtest.Hmeg.Catalog.IntegrationTests

Namespace rename applied across all .cs files and csproj RootNamespace:

  Recordingtest.EgPlugin           -> Recordingtest.Sut.EgBim.PluginHost
  Recordingtest.EngineBridge       -> Recordingtest.Hmeg.Catalog
  Recordingtest.EngineBridge.Client -> Recordingtest.Hmeg.Bridge.Client
  Recordingtest.EngineBridge.Probe -> Recordingtest.Hmeg.Catalog.Probe

New: tests/Recordingtest.Architecture.Tests/

  DependencyGraphTests walks Assembly.GetReferencedAssemblies() for each
  tier and fails if a forbidden reference leaks in:
    - Generic modules must not reference HmEG or any app-specific DLL
    - HmEG-aware modules must not reference app-specific DLLs
    - Recordingtest.Hmeg.Bridge must reference HmEG (positive check)
  11 tests, all passing. Prevents future drift from CLAUDE.md §8.1.

Engine-bridge v3 wire-up (HmEgBridgePlugin.BuildProvider):

  Previously the HmegDirectStateProvider lambdas returned null and the
  chain fell through to reflection. They now call directly into the
  EditorPlugin base class that HmEgBridgePlugin inherits:

    spaceProvider    = () => RootSpace
                           // AppManager.ViewportManager.RootSpace
    viewportProvider = () => View
                           // EGViewport : Control, HmEGViewport
    documentPathProvider = () => AppManager?.FileManager?.CurrentFile

  Every lambda is wrapped in try/catch so plugin construction still
  cannot throw back into the SUT. Editor02.HmEGAppManager.dll added as
  a reference on Recordingtest.Sut.EgBim.PluginHost.csproj — app-
  specific tier, which is allowed by the architecture tests.

Entry points were confirmed from read-only review of the SUT sources at
  D:\GiteaAll\EG-BIM_Modeler\EditorPluginInterface\EditorPlugin.cs
  D:\GiteaAll\EG-BIM_Modeler\HmEGApplicationManagementLibrary\HmEGAppManager.cs
  D:\GiteaAll\EG-BIM_Modeler\HmEGApplicationManagementLibrary\SubManager\FileManager.cs

closing out Q1/Q2/Q6/Q7 from docs/hmeg-api-survey.md.

Tests: 115 -> 126 (+11 Architecture), 0 failures.

Next step: live verification of /scene /camera /selection with a real
SUT session; any discrepancy in HmegDirectStateProvider reflection will
be tightened after observing real HmEG camera field names.

+# 2026-04-09 — 3-tier 분리 2단계 + engine-bridge v3 EgBim 람다 wire-up
+
+**이슈**: #10 follow-up (engine-bridge v3) + `docs/contracts/generic-sut-split.md`
+**소요 시간**: ~110분 (새 세션 / 동일 날짜 두 번째 블록)
+**Context 사용량**: input ~80k / output ~18k tokens (Opus 4.6, 1M context, 새 세션)
+
+## 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 |
+| `src/Recordingtest.EngineBridge.Client/` | `src/Hmeg/Recordingtest.Hmeg.Bridge.Client/` | HmEG-aware |
+| `src/Recordingtest.EngineBridge.Probe/` | `src/Hmeg/Recordingtest.Hmeg.Catalog.Probe/` | HmEG-aware |
+| `tests/Recordingtest.EgPlugin.Tests/` | `tests/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost.Tests/` | App-specific |
+| `tests/Recordingtest.EngineBridge.Tests/` | `tests/Hmeg/Recordingtest.Hmeg.Catalog.Tests/` | HmEG-aware |
+| `tests/Recordingtest.EngineBridge.IntegrationTests/` | `tests/Hmeg/Recordingtest.Hmeg.Catalog.IntegrationTests/` | HmEG-aware |
+
+**네임스페이스 rename**:
+- `Recordingtest.EgPlugin` → `Recordingtest.Sut.EgBim.PluginHost`
+- `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).
+
+### 테스트
+
+- 전체 suite: **126 tests pass** (115 → 126, +11 ArchitectureTests)
+- 구성: Recorder 26 / Player 24 / Sut.EgBim.PluginHost 21 / Normalizer 16 / Architecture 11 / DiffReporter 5 / Runner 6 / Hmeg.Catalog 6 / Hmeg.Catalog.Integration 6 / Hmeg.Bridge 5
+- 빌드/테스트 0 failures
+
+### 분류 라벨 (2단계 완료 후 현재)
+
+| 경로 | 계층 |
+|---|---|
+| `src/Recordingtest.Bridge.Abstractions/` | Generic |
+| `src/Recordingtest.Recorder/`, `.Player/`, `.Normalizer/`, `.DiffReporter/`, `.Runner/`, `.SutProber/`, `.DiffReporter.Cli/` | Generic |
+| `src/Hmeg/Recordingtest.Hmeg.Bridge/`, `.Catalog/`, `.Catalog.Probe/`, `.Bridge.Client/` | HmEG-aware |
+| `src/Sut/EgBim/Recordingtest.Sut.EgBim.PluginHost/` | App-specific (EgBim) |
+
+## 라이브 검증 (대기)
+
+다음 세션의 P1:
+
+1. 본 작업물을 빌드해 `EG-BIM Modeler/Plugins/Recordingtest.Sut.EgBim.PluginHost/` 아래 배포
+2. SUT 실행, 이미 열린 .hmeg 문서가 있으면 Box 등 몇 개 객체 생성 + 선택
+3. 셸에서:
+   ```
+   curl http://localhost:38080/health
+   curl http://localhost:38080/scene     # object_count, document_path
+   curl http://localhost:38080/camera    # eye/target/up/fov 실값
+   curl http://localhost:38080/selection # selected_ids
+   ```
+4. 실값이 기대와 다르면 `HmegDirectStateProvider.GetCamera`의 reflection 멤버 후보 또는 selection walk 로직 보정 1~2회 반복
+
