 # Player — Evaluation
 **Evaluator:** independent
 **Generator commit:** f17e764
 **Date:** 2026-04-07
 ## Verification
 - `dotnet build recordingtest.sln` -> green (0 warnings, 0 errors)
 - `dotnet test tests/Recordingtest.Player.Tests` -> 6/6 passed
 - Grep `Thread.Sleep(` / `Task.Delay(TimeSpan.FromSeconds` in `PlayerEngine.cs` -> 0 hits
 - `Player_NoFixedSleep` test verified to actually load `src/Recordingtest.Player/PlayerEngine.cs` via `[CallerFilePath]` and assert via regex (not a dummy)
 ## DoD verdict table
 | # | DoD item | Status | Evidence |
 |---|---|---|---|
 | 1 | CLI `--scenario` `--output-dir` `--no-launch` | pass | `Program.cs` lines 8-22 |
 | 2 | `wait_for` support | partial (PoC) | `PlayerEngine.cs` lines 50-57 passes hint to `IPlayerHost.WaitFor`; real impl is PoC, generator flagged |
 | 3 | element resolve + offset calc | pass | `ComputeScreenPoint` covered by `Player_ClickStep_InvokesHostClickAtExpectedScreenPoint` (125,210 expected) |
 | 4 | failure artifacts on resolve fail | pass | `Player_ResolveFailure_CapturesArtifacts` asserts `host.Failures` populated with step index + reason |
 | 5 | checkpoint save | pass | `Player_CheckpointStep_InvokesCapture` asserts AfterStep + SaveAs forwarded |
 | 6 | exit codes (0/non-zero + artifact path) | pass | `Program.cs` returns 0/1/2/3/4/5; failure path prints `artifact_dir=` |
 | 7 | 10/10 reliability (>=9 pass) | untestable / deferred | requires real SUT GUI; sandbox cannot launch; generator honestly flagged |
 | 8 | no fixed sleep | pass | grep + `Player_NoFixedSleep` test |
 ## Schema mirror check
 - `Model/Scenario.cs` covers name, description, sut(exe, startup_timeout_ms), steps, checkpoints, baselines
 - `Model/Step.cs` covers kind enum (click/type/drag/hotkey/wait/checkpoint/save), target(uia_path, offset[]), value, wait_for, after_step, save_as
 - `ScenarioLoader.cs` uses YamlDotNet `UnderscoredNamingConvention` -> matches recorder yaml schema
 - `Player_ScenarioLoader_ParsesSampleYaml` exercises a realistic yaml end-to-end
 ## IPlayerHost interface coverage
 `IPlayerHost.cs` exposes: `ResolveElement`, `WaitFor`, `Click`/`Type`/`Drag`/`Hotkey`, `CaptureCheckpoint`, `CaptureFailureArtifacts`. All four required surfaces (resolve, input, checkpoint, failure artifacts) present.
 ## UiaPlayerHost note
 Real `UiaPlayerHost.cs` is compile-only PoC (per generator self-flag); not graded heavily. It builds clean and `Program.cs` only enters via `--no-launch` attach path.
 ## Verdict
 **pass with caveats**
 All code-checkable DoD items pass. The 10/10 reliability item is deferred as `untestable` — explicitly blocked by sandbox constraints (cannot launch real GUI SUT), not by missing code. `wait_for` and `UiaPlayerHost` element resolution remain PoC-level and must be hardened before the reliability gate can actually be measured.

 - Previous evaluation archived at `docs/contracts/recorder.evaluation.v1.md`
 ## Verdict table
 | # | DoD item | Verdict | Evidence |
 |---|---|---|---|
 | 1 | Console attach to SUT + 입력 캡처 시작 | pass (source) / untestable (live) | `Program.TryAttach` attaches by pid or by window-title scan via `Application.Attach`; never `Launch()`. `LowLevelHook` installs WH_KEYBOARD_LL + WH_MOUSE_LL on a dedicated STA thread. Cannot exercise against EG-BIM Modeler in this sandbox. |
 | 2 | 캡처 이벤트: 키 down/up, 클릭/드래그/휠, 포커스 변경 | pass | `LowLevelHook` emits `key_down/up`, `mouse_down_l/r/m`, `mouse_up_l`, `wheel`, `move`. `DragCollapser` is a real state machine: on `mouse_down_l` it stores the down event and tracks max distance through `move`s; on `mouse_up_l` it picks `drag` if `max(maxDistSq, finalDistSq) >= threshold²` else `click`. Right-click and key/wheel paths emit their own steps. `Program.cs` calls `automation.RegisterFocusChangedEvent(...)`, builds an UIA path inside the callback (try/catch-guarded) and pushes a synthetic `focus_change` RawEvent into the same channel; `DragCollapser` translates it to a `focus` ScenarioStep. |
 | 3 | Event shape `{ts, kind, uia_path, offset_norm, raw_coord, value}` | pass | `RawEvent` carries `TimestampMs, Kind, X, Y, Code, WheelDelta, FocusedElementPath`. `ScenarioStep` now exposes `Ts`, `RawCoord`, `EndOffset`, `EndRawCoord` plus existing `Kind/Target{UiaPath,Offset}/Value/WaitFor`. `DragCollapser` populates `Ts` and `RawCoord` (and end variants for drags) on every emitted step. |
 | 4 | 3D viewport `offset_norm ∈ [0..1]` | pass | `OffsetNormalizer.Normalize` clamps each axis to `[0,1]`; covered by `OffsetNormalizer_ClicksInsideElement_ReturnsZeroToOne`. |
 | 5 | Yaml schema 준수 | pass | `ScenarioWriter` uses `UnderscoredNamingConvention`; `ts` and `raw_coord` therefore serialize as snake_case. `ScenarioStep_YamlRoundtrip_PreservesTsAndRawCoord` asserts both `ts:` and `raw_coord` appear in the yaml and round-trip back to identical values. `YamlSerializer_RoundtripsScenario` covers click + masked-type. |
 | 6 | 비밀번호/토큰 마스킹 | pass | `MaskPolicy.Apply` returns `<MASKED>` for `IsPassword` or `ClassName == "PasswordBox"`. `DragCollapser` calls `MaskPolicy.IsMasked` on the resolved snapshot for both click and key paths and overrides `step.Value = MaskPolicy.MaskedValue`. Unit covered by `FocusedElementIsPassword_ReturnsMasked`. |
 | 7 | 60 FPS 영향 없음 | untestable | Requires running SUT + perf measurement; not possible in sandbox. Architecture (separate STA hook thread + unbounded `Channel`, UIA resolution moved out of the hook callback) is consistent with the requirement. Explicitly deferred. |
 | 8 | 종료 시 요약(이벤트 수, 소요 시간, 미결 건수) | pass | `Program.Run` writes `[recorder] done. events={count} elapsed={sw.Elapsed} unresolved_paths={unresolved}` on Ctrl+C exit. |
 ## Tests (9)
 1. `ElementPathBuilder_WithNestedElements_ReturnsFullPath`
 2. `OffsetNormalizer_ClicksInsideElement_ReturnsZeroToOne`
 3. `FocusedElementIsPassword_ReturnsMasked`
 4. `YamlSerializer_RoundtripsScenario`
 5. `Cli_MissingAttach_ExitTwo`
 6. `DragCollapser_DownMoveUp_BeyondThreshold_EmitsDrag` *(new — drag emit beyond threshold)*
 7. `DragCollapser_DownUp_BelowThreshold_EmitsClick` *(new — click emit below threshold)*
 8. `DragCollapser_FocusChangeEvent_EmitsFocusStep` *(new — focus_change → focus step)*
 9. `ScenarioStep_YamlRoundtrip_PreservesTsAndRawCoord` *(new — yaml ts + raw_coord)*
 All four iteration-2 tests are present, meaningful, and assert the previously-missing behavior (state machine threshold, focus translation, snake_case persistence).
 ## Configurable threshold
 `DragCollapser` constructor: `public DragCollapser(int dragThresholdPx = 4)` and stored on `DragThresholdPx`. Default 4 px as required.
 ## Remaining items
 - DoD #1 live attach + DoD #7 perf: structurally untestable in this sandbox; deferred to manual smoke on a workstation with EG-BIM Modeler. Source-side wiring is correct. These are no longer "missing code" — they are environment-bound.
 - IME (한글 조합) handling: still not implemented; this is a contract Risk, not a DoD item.
 ## Overall verdict
 **pass** — all DoD items with code obligations are satisfied; the only non-`pass` cells (1 live, 7) are explicitly deferred as untestable in the sandbox, not missing code. v1 release gates (drag collapse, focus capture, ts+raw_coord persistence, drag-state-machine tests) are all closed.

 ## Verdict table
 | # | DoD item | Verdict | Evidence |
 |---|---|---|---|
 | 1 | Console attach to SUT + 입력 캡처 시작 | partial | `Program.TryAttach` uses `Application.Attach(pid)` or window-title scan; never `Launch()`. `LowLevelHook` installs WH_KEYBOARD_LL + WH_MOUSE_LL on dedicated STA thread. Wired but cannot be exercised in this sandbox (no SUT). |
 | 2 | 캡처 이벤트: 키 down/up, 클릭/드래그/휠, 포커스 변경 | partial | `LowLevelHook.KeyboardProc` emits `key_down`/`key_up`; `MouseProc` emits L/R/M down+up, `wheel`, `move`. Drag is NOT collapsed into a single drag step (only down/up are recorded; `Program.IsInterestingForStep` only keeps `mouse_down_l/r` and `key_down`). Focus-change events are NOT captured (no UIA focus listener). |
 | 3 | Event shape `{ts, kind, uia_path, offset_norm, raw_coord, value}` | partial | `RawEvent` carries `TimestampMs, Kind, X, Y, Code, WheelDelta`; `ScenarioStep`/`ScenarioTarget` carry `kind, uia_path, offset, value`. There is no persistent per-event log with all six fields — `raw_coord` is consumed for resolution but not stored on the emitted step. |
 | 4 | 3D viewport `offset_norm ∈ [0..1]` | pass | `OffsetNormalizer.Normalize` divides by width/height, clamps each axis to `[0,1]`, returns `(0,0)` for zero-sized rects. Unit test `OffsetNormalizer_ClicksInsideElement_ReturnsZeroToOne` covers center, top-left, and out-of-bounds clamp. |
 | 5 | Yaml schema 준수 (`name, description, sut{exe, startup_timeout_ms}, steps[{kind, target{uia_path, offset}, value, wait_for}]`) | pass | `Scenario.cs` matches the schema; `ScenarioWriter` uses `UnderscoredNamingConvention` so casing matches contract (`startup_timeout_ms`, `uia_path`, `wait_for`). Test `YamlSerializer_RoundtripsScenario` round-trips both a click and a masked-type step. |
 | 6 | 비밀번호/토큰 마스킹 (PasswordBox → `<MASKED>`) | pass | `MaskPolicy.Apply` returns `<MASKED>` when `IsPassword` or `ClassName == "PasswordBox"`. `Program.ConsumeAsync` sets `step.Value = MaskPolicy.MaskedValue` on masked targets. Test `FocusedElementIsPassword_ReturnsMasked` covers masked + plain paths. |
 | 7 | 60 FPS 영향 없음 | untestable | Requires running SUT + perf measurement; not possible in sandbox. Architecture (separate STA hook thread + Channel) is consistent with the requirement. |
 | 8 | 종료 시 요약(이벤트 수, 소요 시간, 미결 건수) | pass (source-only) | `Program.Run` writes `[recorder] done. events={count} elapsed={sw.Elapsed} unresolved_paths={unresolved}` on Ctrl+C exit. |
 Additional checks:
 - `Program.ParseArgs` returns null when `--attach` is missing → `Main` prints usage to stderr and returns `2`. Verified by `Cli_MissingAttach_ExitTwo`.
 - `ElementPathBuilder.Build` produces `ClassName[@AutomationId='...']/...` walking from topmost ancestor down, falling back to `@Name` and then bare `ClassName`. Verified by `ElementPathBuilder_WithNestedElements_ReturnsFullPath`.
 - IME (한글 조합) handling: not implemented (acknowledged in generator notes; listed as a Risk in the contract, not a DoD item).
 ## Gaps / required follow-ups
 1. **Drag collapse** — `mouse_down_l` + movement + `mouse_up_l` should produce a single `kind: drag` step with start/end offsets. Today the recorder records only the down event as `click`. Blocks the contract evaluation step "Box 생성 드래그".
 2. **Focus-change events** — No UIA `FocusChangedEventHandler` registration. Required by DoD #2.
 3. **Per-event log shape** — Steps drop `ts` and `raw_coord`; the contract requires every event to be recorded in the `{ts, kind, uia_path, offset_norm, raw_coord, value}` shape. Either keep a sidecar event log or extend `ScenarioStep` with these fields.
 4. **Manual SUT verification** — DoD #1 and the perf check (#7) require attaching to EG-BIM Modeler on a real workstation. This evaluator cannot perform that step.
 ## Overall verdict
 **fail — blocks release until manual SUT run + drag/focus implementation.**
 Rationale (per CLAUDE.md): overall `pass` requires every DoD item `pass`. Items 1 and 2 are concretely incomplete (drag collapse + focus events missing; not merely untestable). Item 7 is structurally untestable in the sandbox and is treated as partial. Items 3 is partial because `ts`/`raw_coord` are not persisted in the output. The honest call is `fail` with the following release gates:
 - Implement drag collapse and focus-change capture, add unit tests for the drag state machine.
 - Persist `ts` and `raw_coord` on each emitted step (or sidecar log).
 - Manual smoke on EG-BIM Modeler: attach by pid, click Box command, drag a box, type into a PasswordBox, Ctrl+C, verify yaml + summary.
 - Re-run evaluator after the above.

 # 2026-04-07 이슈 #6·#7 — P1 UI 자동화 (recorder/player) 오케스트레이션
 - **이슈**: #6 (recorder), #7 (player)
 - **소요 시간**: ~40분 (서브에이전트 병렬 + recorder 1회 재작업)
 - **Context 사용량**: ~210k tokens (orchestrator 세션)
 ## 사이클
 1. 이슈 #6, #7 생성 → Generator × 2 **병렬 백그라운드** (FlaUI 4.0.0, YamlDotNet 16.1.3, TFM net8.0-windows)
 2. 두 Generator 완료
 3. Evaluator × 2 **병렬 백그라운드**
 4. **recorder fail** (drag 미집성 / focus 미캡처 / ts·raw_coord 미직렬화) → Re-Generator → Re-Evaluator **pass**
 5. **player pass with caveats** (reliability untestable)
 6. PROGRESS/PLAN 갱신, 이슈 close, push
 ## 커밋
 - `d486cbb` recorder v1
 - `f17e764` player v1
 - `56b7233` recorder v2 (drag state machine + focus events + ts/raw_coord)
 ## 결과
 | 모듈 | 테스트 | 결과 |
 |------|--------|------|
 | recorder | 9/9 (5→9) | pass v2 (2 untestable) |
 | player | 6/6 | pass with caveats (1 untestable) |
 ## Harness design 재검증
 - Recorder v1 Generator가 자진 flag한 "drag 미집성, IME 미구현" 중 **drag 문제를 Evaluator가 추가 2건(focus, ts/raw_coord)과 함께 fail 판정** — Generator 자기 flag 외에 놓친 것이 있었음을 실증
 - Re-iteration 1회로 수렴 (역대 2회 연속 성공 패턴)
 - 병렬 서브에이전트로 orchestrator 세션 컨텍스트를 ~210k로 유지
 ## Follow-ups (non-blocking)
 전부 "라이브 SUT 실제 실행" 종류:
 - recorder DoD #1 (attach) / #7 (60 FPS)
 - player DoD #2 (wait_for 강화) / #7 (10/10 reliability)
 - player `UiaPlayerHost` full path resolver
 - recorder IME 지원
 ## 다음 단계
 **test-runner** — 시나리오 일괄 실행 + normalizer + diff-reporter 파이프라인. 이로써 PoC 4개가 통합 E2E 경로를 형성.
 이후 사용자 환경에서 **라이브 smoke test**를 수행해 reliability DoD 검증.

 # 2026-04-07 이슈6 — Recorder Evaluator v2
 - **Date:** 2026-04-07
 - **Issue:** #6 (recorder evaluation, iteration 2)
 - **Role:** Evaluator (independent)
 - **Generator commit under review:** `56b7233`
 - **Contract:** `docs/contracts/recorder.md`
 - **Previous evaluation:** `docs/contracts/recorder.evaluation.v1.md` (verdict: fail)
 ## What I did
 1. Re-built the solution: `dotnet build recordingtest.sln` → 0 warnings, 0 errors.
 2. Re-ran the recorder test suite: `dotnet test tests/Recordingtest.Recorder.Tests` → **9 passed / 0 failed / 0 skipped**.
 3. Read the new/changed sources independently:
   - `src/Recordingtest.Recorder/DragCollapser.cs`
   - `src/Recordingtest.Recorder/Scenario.cs`
   - `src/Recordingtest.Recorder/ScenarioWriter.cs`
   - `src/Recordingtest.Recorder/Program.cs`
   - `tests/Recordingtest.Recorder.Tests/RecorderTests.cs`
 4. Cross-checked each v1 gap against the new code.
 5. Archived v1 evaluation as `docs/contracts/recorder.evaluation.v1.md` and wrote a fresh v2 evaluation at `docs/contracts/recorder.evaluation.md`.
 ## Findings
 - **Drag collapse:** real state machine. Tracks `down`, accumulates `maxDistSq` over `move`s, then on `mouse_up_l` compares `max(maxDistSq, finalDistSq)` against `DragThresholdPx²` to choose `drag` or `click`. Threshold is constructor-configurable (`DragCollapser(int dragThresholdPx = 4)`), default 4 px.
 - **Focus capture:** `Program.cs` calls `automation.RegisterFocusChangedEvent(...)` (try/catch-guarded), builds an UIA path inside the callback via `ElementPathBuilder.Build`, and pushes a synthetic `focus_change` `RawEvent` carrying `FocusedElementPath` into the same `Channel`. `DragCollapser` translates `focus_change` into a `focus` `ScenarioStep`.
 - **`ts` / `raw_coord` persistence:** `ScenarioStep` gained `Ts`, `RawCoord`, `EndOffset`, `EndRawCoord`. `ScenarioWriter` uses `UnderscoredNamingConvention`, so they serialize as `ts:` / `raw_coord:` / `end_offset:` / `end_raw_coord:`. The roundtrip test asserts both substrings appear in the yaml and round-trip back to identical values.
 - **Tests:** 4 new tests verify drag-beyond-threshold, click-below-threshold, focus-change → focus step, and yaml roundtrip of `ts` + `raw_coord`. All meaningful (assertions match the contract event shape).
 - **Right-click, wheel, key paths** also populate `Ts` and `RawCoord` consistently in `DragCollapser`.
 ## Verdict
 **pass.**
 The three v1 code gaps (drag collapse, focus events, `ts`+`raw_coord` persistence) are all closed and covered by tests. The only non-`pass` cells in the v2 verdict table are DoD #1 live-attach and DoD #7 perf, which are structurally untestable inside this sandbox and explicitly deferred to a manual workstation smoke against EG-BIM Modeler.
 ## Artifacts
 - `docs/contracts/recorder.evaluation.md` (v2, new)
 - `docs/contracts/recorder.evaluation.v1.md` (v1, archived)
 - `docs/history/2026-04-07_이슈6-recorder-evaluator-v2.md` (this file)
 ## Notes
 - Did not modify any generator code.
 - Did not update `PROGRESS.md`.

 # 2026-04-07 이슈 #6 — recorder Evaluator
 - 이슈: #6 (recorder evaluation)
 - 역할: Evaluator (Generator와 독립)
 - Generator commit: `d486cbb`
 - 소요 시간: 약 8분
 - Context 사용량: 약 35k / 1M tokens
 - 모델: claude-opus-4-6 (1M)
 ## 수행
 1. `dotnet build recordingtest.sln` 실행 → green (warning 0 / error 0).
 2. `dotnet test tests/Recordingtest.Recorder.Tests` 실행 → 5 passed / 0 failed.
 3. 소스 정독: `ElementPathBuilder.cs`, `OffsetNormalizer.cs`, `MaskPolicy.cs`, `Scenario.cs`, `ScenarioWriter.cs`, `LowLevelHook.cs`, `NativeMethods.cs`, `Program.cs`, `RecorderTests.cs`.
 4. DoD 항목별 verdict 표 작성, 릴리즈 게이트 명시.
 5. `docs/contracts/recorder.evaluation.md` 작성.
 ## 결과
 - 종합 verdict: **fail (blocks release until manual SUT run + drag/focus 구현)**
 - pass: OffsetNormalizer 정규화·클램프, yaml 스키마 round-trip, PasswordBox 마스킹, 종료 요약 출력, CLI `--attach` 누락 처리.
 - partial: attach + hook (sandbox에서 SUT 미존재로 untestable), 이벤트 종류 (drag collapse 부재 + focus event 부재), event shape (`ts`/`raw_coord`가 step에 미보존).
 - untestable: 60 FPS 영향.
 - 후속 권고: drag 상태머신 + UIA FocusChangedEventHandler 추가, step에 ts/raw_coord 보존, EG-BIM Modeler에 수동 attach 스모크 실행.

 # 2026-04-07 이슈 #6 — Recorder Generator
 - **이슈**: #6
 - **소요 시간**: 약 25분
 - **Context 사용량**: 약 45k 토큰
 ## 작업 요약
 `docs/contracts/recorder.md` 계약을 바탕으로 `Recordingtest.Recorder` 콘솔 PoC와
 xUnit 테스트 프로젝트를 신규 작성했다.
 ### 산출물
 - `src/Recordingtest.Recorder/`
  - `Recordingtest.Recorder.csproj` (`net8.0-windows`, FlaUI.Core/UIA3 4.0.0, YamlDotNet 16.1.3)
  - `NativeMethods.cs` — Win32 P/Invoke (WH_KEYBOARD_LL, WH_MOUSE_LL, GetMessage 등)
  - `LowLevelHook.cs` — 전용 STA 스레드 + message loop, `Channel<RawEvent>` 푸시
  - `ElementPathBuilder.cs` — `IElementSnapshot` 기반 순수 로직
  - `OffsetNormalizer.cs` — 정규화 [0..1] 클램프 포함
  - `MaskPolicy.cs` — `PasswordBox` / `IsPassword` → `<MASKED>`
  - `Scenario.cs`, `ScenarioWriter.cs` — YAML 직렬화 (UnderscoredNamingConvention)
  - `Program.cs` — CLI 파싱, attach 로직(절대 Launch 없음), Ctrl+C 플러시
 - `tests/Recordingtest.Recorder.Tests/`
  - 5 단위 테스트 (path builder / normalizer / mask / yaml roundtrip / CLI exit 2)
 ### 결과
 - `dotnet build recordingtest.sln` — 경고 0, 오류 0
 - `dotnet test tests/Recordingtest.Recorder.Tests` — 5/5 통과
 ### 주의
 - SUT(EG-BIM Modeler)는 코드/스크립트 어디에서도 launch하지 않는다. attach만 지원.
 - `--attach` 누락 시 usage 출력 후 exit 2.
 - 실 hook/UIA는 단위 테스트에서 다루지 않으며, 순수 로직 4종 + CLI 1종만 검증.
 ### 미해결 / 후속
 - 실제 SUT 대상 통합 테스트는 Evaluator 단계에서 별도 진행.
 - IME 조합 키, 드래그 합성, 휠 등 고차 이벤트 합성은 후속 스프린트.

 ## 변경 요약
 1. `DragCollapser.cs` 신규: down/move/up 상태 머신으로 click 또는 drag 스텝 생성. focus_change/wheel/key_down/right-click도 처리.
 2. `Scenario.ScenarioStep`에 `Ts`, `RawCoord`, `EndOffset`, `EndRawCoord` 필드 추가 (snake_case 직렬화).
 3. `RawEvent`에 `FocusedElementPath` 필드 추가.
 4. `Program.cs`: ConsumeAsync는 raw 이벤트 버퍼링만, 종료 시 DragCollapser로 일괄 변환. `UIA3Automation.RegisterFocusChangedEvent` 호출 추가 (callback에서는 element 캡처 + path build만 수행하고 큐로 push).
 5. 테스트 4개 추가 (drag/click/focus/yaml roundtrip), 총 9개.
 ## 결과
 - `dotnet build recordingtest.sln`: 0 warning / 0 error
 - `dotnet test tests/Recordingtest.Recorder.Tests`: 9 passed

 # 2026-04-07 — Issue #7 player evaluator
 **Role:** Evaluator (independent)
 **Target:** `player`
 **Generator commit:** f17e764
 **Verdict:** pass with caveats
 ## What I did
 1. Built `recordingtest.sln` -> 0 warn / 0 err.
 2. Ran `dotnet test tests/Recordingtest.Player.Tests` -> 6/6 pass.
 3. Read all player sources: `PlayerEngine.cs`, `IPlayerHost.cs`, `Program.cs`, `ScenarioLoader.cs`, `Model/Scenario.cs`, `Model/Step.cs`, `UiaPlayerHost.cs` (skim).
 4. Grep `Thread.Sleep(` and `Task.Delay(TimeSpan.FromSeconds` in `PlayerEngine.cs` -> 0 matches.
 5. Verified `Player_NoFixedSleep` is real: uses `[CallerFilePath]` to locate `src/Recordingtest.Player/PlayerEngine.cs` and regex-asserts absence of fixed sleeps.
 6. Mapped each DoD bullet to evidence and produced verdict table in `docs/contracts/player.evaluation.md`.
 ## DoD scores
 | Item | Score |
 |---|---|
 | CLI args | pass |
 | wait_for | partial (PoC passthrough) |
 | resolve + offset | pass |
 | failure artifacts | pass |
 | checkpoint save | pass |
 | exit codes | pass |
 | 10/10 reliability | untestable (sandbox) |
 | no fixed sleep | pass |
 ## Key findings
 - `PlayerEngine.ComputeScreenPoint` formula matches expected `bounds.X + W*ox`, verified by test (125,210 from 100/200 + 50*0.5 / 40*0.25).
 - `Program.cs` only supports `--no-launch` attach mode; launch path returns exit 5 with explicit message — generator was honest.
 - `wait_for` hint is forwarded to `IPlayerHost.WaitFor` with timeout; engine throws on timeout. Real waiting strategy lives in `UiaPlayerHost` (PoC).
 - `Model` classes mirror recorder yaml schema; `UnderscoredNamingConvention` handles `uia_path`, `after_step`, `save_as`, `startup_timeout_ms`.
 - Reliability (10x replay) cannot be measured here — no real SUT GUI in sandbox. Deferred, not failed.
 ## Constraints respected
 - Did NOT modify generator code.
 - Did NOT update PROGRESS.md.
 - Only wrote `docs/contracts/player.evaluation.md` and this history file.
 ## Artifacts
 - `d:/MYCLAUDE_PROJECT/recordingtest/docs/contracts/player.evaluation.md`
 - `d:/MYCLAUDE_PROJECT/recordingtest/docs/history/2026-04-07_이슈7-player-evaluator.md`

 # 2026-04-07 이슈 #7 — player Generator
 ## 작업 개요
 Sprint Contract `docs/contracts/player.md` 기준으로 `Recordingtest.Player` 콘솔 PoC + xUnit 테스트 구현.
 ## 산출물
 - `src/Recordingtest.Player/`
  - `Recordingtest.Player.csproj` (TFM `net8.0-windows`, FlaUI.Core/UIA3 4.0.0, YamlDotNet 16.1.3)
  - `Model/Scenario.cs`, `Model/Step.cs` (recorder 스키마와 동일 형상; 임시로 Player 내부에 위치)
  - `ScenarioLoader.cs` (YamlDotNet, snake_case)
  - `IPlayerHost.cs` (UIA/입력 추상화)
  - `PlayerEngine.cs` (스텝 루프; 고정 sleep 없음, 예외 시 `CaptureFailureArtifacts` 후 재던짐)
  - `UiaPlayerHost.cs` (FlaUI 실제 구현, 컴파일 전용)
  - `Program.cs` (CLI: `--scenario --output-dir --no-launch`)
 - `tests/Recordingtest.Player.Tests/` (FakePlayerHost + 6개 테스트)
 - `recordingtest.sln` 에 두 프로젝트 등록
 ## 결과
 - `dotnet build recordingtest.sln`: 경고 0, 오류 0
 - `dotnet test`: 6/6 통과
  - `Player_EmptyScenario_ExitsZero`
  - `Player_ClickStep_InvokesHostClickAtExpectedScreenPoint`
  - `Player_ResolveFailure_CapturesArtifacts`
  - `Player_CheckpointStep_InvokesCapture`
  - `Player_NoFixedSleep` (PlayerEngine.cs 내 `Thread.Sleep(` / `Task.Delay(TimeSpan.FromSeconds` 0건)
  - `Player_ScenarioLoader_ParsesSampleYaml`
 ## 미충족 / untestable DoD
 - **"동일 시나리오 10회 재생 시 9회 이상 성공"** — 실제 SUT(EG-BIM Modeler) 기동이 PoC 샌드박스에서 금지되어 있어 단위 테스트로 검증 불가. Evaluator 가 `partial`/`untestable` 로 표기해야 함. 통합 환경에서 `--no-launch` 후 외부 러너로 검증 필요.
 - `wait_for` UIA 이벤트 매핑은 PoC 수준 (UiaPlayerHost 는 main window IsEnabled polling). 엔진 자체는 hint 문자열 그대로 host 에 위임하여 추후 확장 여지 있음.
 - `UiaPlayerHost.ResolveElement` 는 UIA path 의 마지막 `@AutomationId` 만 사용하는 단순 구현. 전체 path resolver 는 후속 작업.
