## Missing evidence (primary finding)

**No visible two-window z-order swap exists in the decoded recording.** Do not treat any timestamp as that onset.

Target effect: two overlapping owned windows titled Work (light, BGR `0x00FBF7F5`) and Arena panel (orange, BGR `0x0078FF` / RGB `#FF7800`), about 1612×907, handles `7737670` and `12652182`, Python pid `2992`. Swap IN FRONT / BEHIND every 1.5 s for 24 s, then close. This is not Hide and not minimize.

Checks:

- Contact sheet at 0.5 fps across the 127.625 s source, plus 1920×1080 stills during prompt, tool use, Python run, reply, and hold.
- Accurate stills at decoded timestamps around submission (4.000–11.000), Read/Run UI (40.000–60.000), the Python pid interval (61.000–87.125), and the completed reply (90.000–101.875). Mid-run stills at 60.250 s, 61.375 s, 64.000 s, 66.000 s, 70.000 s, and 76.000 s show only the maximized WorkBuddy conversation.
- RGB orange scan of every decoded source frame at 480×270 with `-fps_mode passthrough`: 1000 frames inspected, matching ffprobe. Peak 12 orange-like pixels at 127.500 s (desktop after WorkBuddy closed). A 1612×907 panel would occupy on the order of 22,845 pixels at that scale. Hit count at threshold 2500 is 0. During 60–88 s the peak is 2 pixels (taskbar/icon noise).
- `native-window-observations.jsonl` lists one repeating visible window: WorkBuddy bounds `[-6, -6, 1543, 823]` on 500 samples. `maxVisibleCount` is 1. It never lists Python pid `2992` as a window owner, never lists handles `7737670` or `12652182`, `panelLikeCount` is 0, and `overlappingPairSamples` is 0. Pid `2992` is present from 61.360 s through 87.107 s (span 25.747 s) with **zero** enumerated windows.

The Agent public reply claims the script completed (pid 2992, 1612×907 windows, handles 7737670 / 12652182, 24 s IN FRONT / BEHIND swap, `SetWindowPos` + `SetForegroundWindow`, summary `status: complete`). That text is **not** the desktop measurement. The desktop capture during `Run foreground-window.py unchanged` and pid `2992` shows only the maximized WorkBuddy conversation. No orange overlay, no light Work window, no IN FRONT / BEHIND labels, no stacking-order swap.

`confirmations.json` is `[]`. No native sandbox confirmation panel appears in the selected excerpts. No approval screenshot is returned.

## Selected moments (labeled candidate, not an invented onset)

Recipe: `preview-moments-v1.json`. Three objects, decoded timestamps:

| Stage | Source start | Duration | Basis |
| --- | --- | --- | --- |
| `opening` | 5.000 s | 5 s | Prompt already readable in the composer. Submission is between 9.000 s (composer still showing the request, send arrow) and 9.250 s (composer empty, stop control). User bubble is readable at 9.625 s after the 9.625→9.875 gap. Opening 5.000–10.000 includes readable prompt, submit, and user bubble. |
| `effect` | 60.250 s | 10 s | **No-observed-effect candidate.** About one second before pid `2992` (first sample 61.360 s). 60.250 s already shows `Run foreground-window.py unchanged`. The two owned windows do not appear. |
| `response` | 96.000 s | 5 s | First fully completed English public reply: pid 2992, 1612×907 windows, handles 7737670 / 12652182, 24 s IN FRONT / BEHIND, summary `status: complete`, send control restored, DeepSeek-V4 Pro 21:11. 95.000 s still shows `Generating response` and the stop control. Matches `agent-output.txt` / `final-screen.png`. |

Related UI times that are **not** a z-order-swap onset:

- 4.000 s: empty composer (`No conversation history`).
- 4.500 s: prompt in the composer.
- 48.000 s: first `Read foreground-window.py`.
- 50.000 s: first `Run foreground-window.py`.
- 87.000–87.125 s: pid `2992` ending; UI shows Thinking. No window close is visible.

Omitted from the 10 s middle excerpt: the Read/Run UI before 60.250 s, the rest of the Python run (about 70.250–87.107 s), and any later closure. The overlapping windows cannot be shown because they are not in the source.

Shorter approval lead-in: not applicable. `confirmations.json` is `[]`. `approval-scope.json` grants are empty. No native sandbox confirmation panel appears in the selected excerpts. No approval screenshot is returned.

## Exports

## Source timing

- `recording.mp4`: 127.625 s, 3840×2160, 1000 decoded frames, first 0.000 s, last 127.500 s.
- Median frame interval 0.125 s. 21 gaps of 0.250 s, including 9.625→9.875 around submission (user-bubble appearance).
- `finalHoldSeconds` 30. The last ~30 s is a hold after the completed reply at 96.000 s. Source last frame 127.500 s and full-timeline last frame 19.984375 s show WorkBuddy closed and the desktop icons (`DeepSeek Harness`, `FinShield`, `WorkBuddy`, standard Chinese shell folders). No credentials observed.

## Verification

Moments preview:

- Duration 20.000 s, 1920×1080, 160 frames at 8 fps, last timestamp 19.875 s.
- Stage boundaries present at 5.000 s and 15.000 s (exact, within one 0.125 s source frame).
- Opening includes composer text (output 0.000 s and 4.000 s), submit (output 4.250 s / 4.375 s), and the submitted user bubble (output 4.625 s / 4.875 s).
- Effect segment first frame is the 60.250 s lead-in (output 5.000 s, `Run foreground-window.py unchanged`, Processed 51 s). Pid `2992` is inside the segment (output 6.000 s ≈ source 61.250 s). Later effect frames (output 10.000–14.875 s) remain the maximized WorkBuddy conversation. **Z-order-swap onset is not inside the segment because it does not exist.**
- Response segment shows the completed public reply at 15.000 s and 19.875 s. No approval panel.
- Provenance `sourceSha256` `053fa9cd30cfc60e5aa0fe40afd23b2b55743005ebfe813d4511afda84a1b0da` matches a post-export hash of `recording.mp4`.
- Output hash `e8582278d67524999bdb92d2e22dc1422acc7e3f2ae2efc31b37a7e398280fad`.

Full-timeline preview:

- Duration 20.000 s, 1920×1080, 1280 frames at 64 fps, last timestamp 19.984375 s.
- Same source hash. Output hash `35793823278e5752041952a299d5c7b6bb19569b79c8d8c4b8a2664c63ed82b2`.
- Opening of this file is empty `Arena controlled trial`. Output 1.000 s is the prompt in the composer. Output 9.625 s (source about 61.4 s, pid `2992`) is still the maximized WorkBuddy conversation, with no overlapping windows. Output 15.000 s is the completed reply. Output 19.875 s shows WorkBuddy closing over the desktop; the last frame 19.984375 s is the desktop after WorkBuddy closed. No credentials observed. No z-order swap.
