## 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.
