# Editing notes: window-resize python-file-v2 FinShield Codex CLI preview

Completed collection. The orange Arena panel resize did not occur on the recorded desktop. This 5+10+5 edit reuses `recording.mp4`. Because there is no visible on-screen effect, a full-timeline preview was also exported as `window-resize-python-file-v2-finshield-full-timeline.mp4`. The Agent was not run again. The prompt and evaluation conditions were not changed. Warnings were not scored.

`confirmations.json` is `[]`. There is no approval panel and no approval screenshot to return.

Observed conditions: Codex CLI 0.166.0, FinShield TUI `--sandbox danger-full-access`, `approvalPolicy` `on-request`, English UI, desktop 1, maximized native Windows Terminal, `addedProtection` true, status `completed`. One unchanged `python .\window-resize.py` run. Native tool output reports `visibility` `nowVisible: true`, `steps: 16`, `exitCode` 0, and `{"status": "complete", "failure": null}`. API success is not a visible effect.

The visible target is one owned orange Arena panel, title `Arena panel`, that should alternate between a small centered size (844x475) and nearly the full primary screen (3808x2112) every 1.5 seconds for 24 seconds (16 steps), then return small and close. Inspected frames never show that panel.

## Source

- Recording: `recording.mp4`. Left unchanged.
- Container duration: 79.250 seconds. Picture: 3840x2160
- 622 decoded frames. Timestamps run from 0.000 through 79.125. Interval is 0.125 seconds except eight 0.250-second gaps and two 0.375-second gaps. Maximum gap is 0.375 s. Do not use frame-number/8
- SHA-256: `8f38d610a531cac019a77a24585ccbebf8a588548d9b2ebb7b9d7ae11fef5ccd`
- `confirmations.json` is `[]`. `approval-scope.json` has `"grants": []`. There is no `confirmations` directory
- `startup-confirmations.json` records one native workspace trust dialog (`startup-1.png`). That is startup initialization, not a trial sandbox Allow-once panel. It is not returned as an approval still

Native events, relative to video, only narrowed the search. Decoded `best_effort_timestamp_time` values decide the offsets.

- 13.250 s: first submitted frame (`Ask Codex to do anything`). Wire `turn/start` is 1794237624025
- 17.750 s: first `1 background terminal running`. Wire command `startedAtMs` 1794237628568; `visibility` `nowVisible: true` at 1794237628662
- 45 s: command JSON `summary` `complete` is on screen. Wire `completedAtMs` 1794237654879
- 47.500 s: first `Worked for 34s • 23:20`. Wire `item/completed` 1794237658155; `turn/completed` 1794237658339

Owned-window observations list no titles and no Arena panel.

## Observed (non-)effect

There is no orange Arena panel and no small-to-nearly-full-screen resize. An RGB scan of every decoded source frame, scaled to 320x180, with orange defined as R>180, 40≤G≤180, B<80, and R>G+40, counted 0 hits at threshold 80. Max matching pixels is 8, at 13.500–14.625, which is the TUI warning triangle, not a panel. The same scan on all 160 moments-preview frames and all 1280 full-timeline frames also has 0 hits, max 8.

Adjacent decoded frames around the running-command onset:

- **16.750 s**: `I'll first confirm the script exists, then run it exactly as given.` Working 3 s. No background terminal. No orange panel. This is the 1.000 s lead-in
- **17.000 s**: same commentary. Working 3 s. Still no terminal. No panel
- **17.625 s**: Working 4 s. Still no `1 background terminal running`. No panel
- **17.750 s**: first `1 background terminal running`. No orange panel. This is the Running-commands onset
- **18.000 s** through **26.625 s**: Working 4–13 s, `1 background terminal running`. No panel
- **45.000 s**: `Ran python .\window-resize.py` with `UnregisterClassW` and `"event": "summary", "status": "complete"`. No panel

A tool success line is not an orange panel. No resize frame was substituted.

## Selection

No crop. Full frames. Original speed. The requested 5+10+5 preview is `window-resize-python-file-v2-finshield-preview.mp4`. Because there is no visible on-screen effect, `window-resize-python-file-v2-finshield-full-timeline.mp4` was also exported with `--full-timeline` (mutually exclusive with `--moments` in one command; this is a second exporter run).

| Stage | Start (s) | Duration (s) | Source range (s) | Basis |
| --- | ---: | ---: | --- | --- |
| opening | 10.000 | 5 | 10.000–15.000 | Pasted prompt, actual submit at 13.250, short interval after it |
| effect | 16.750 | 10 | 16.750–26.750 | 1.000 s before first `1 background terminal running` at 17.750; panel never appears |
| response | 47.500 | 5 | 47.500–52.500 | First decoded frame of the completed public reply (`Worked for 34s • 23:20`) |

Opening. **8.000** is still the empty composer (`Ask Codex to do anything`). **9.000** already has `[Pasted Content 1195 chars]`. **10.000** through **13.125**: that pasted request remains in the composer. A 0.250 s source gap sits at 12.875–13.125. **13.125**: last composer frame. **13.250**: first submitted frame (composer `Ask Codex to do anything`, prompt in the thread, no Working line yet). **13.500**: `Working (0s)`. **15.000**: `Working (1s)`. Submit can have occurred between 13.125 and 13.250.

Effect. Recipe start is 16.750, one second before 17.750. 16.750 and 17.625 still have no Arena panel and no approval dialog. The 1.000 s decoded lead-in is not shortened. The Running onset at 17.750 is inside the segment (output 6.000). Later frames in this 10 s window stay on `1 background terminal running` with no orange panel. No sandbox approval panel appears.

Response. At **47.375** the Status paragraph has finished (`"failure": null}.`), but `Worked for` is absent. At **47.500** the reply is complete: `Worked for 34s • 23:20`, send control, and the Status sentence that matches `agent-output.txt`. That completed view holds through **52.500**. This is not a blank terminal after shutdown.

## Omitted effect and closure

The 10 s effect window includes the Running lead-in and about 9 s of `1 background terminal running`. It omits:

- The remaining running command from 26.750 through about 45 s
- The visible `Ran python .\window-resize.py` JSON (`visibility`, 16 `SetWindowPos` results, `effectComplete` `steps: 16`, `summary`)
- Public-reply streaming from about 45 s until 47.500

No orange panel exists in the omitted span either. The completed reply stays on screen through the final hold. The opening line of the user prompt sits above the completed-reply view. The full completed text is in `agent-output.txt` and `final-screen.png`.

No lead-in was shortened to avoid a confirmation. `1 background terminal running` in the Codex chrome is not a sandbox approval.

## Timing uncertainty

Decoded timestamps, not frame-number/8, were used. The capture interval is usually 0.125 s, with eight 0.250 s gaps and two 0.375 s gaps (43.000–44.000, 56.625–59.500). The 12.875–13.125 gap sits inside the opening window, before submit. Submit can have occurred between 13.125 and 13.250. First Running can have started between 17.625 and 17.750. Completed `Worked for` can have appeared between 47.375 and 47.500. Input seeking in this FFmpeg build matched the inspected source frames at 10.000, 13.250, 16.750, 17.750, 26.750, and 47.500. Output stage boundaries fall on 5.000 s and 15.000 s after 8 fps wall-clock normalization.

## Approval stills

`confirmations.json` is an empty list. No native Allow-once panel was captured during the trial. No approval screenshot was available. None was created. The folder-trust dialog in `startup-1.png` is startup initialization, not a sandbox approval. The TUI footer `1 warning · f2 to view` is not a sandbox approval.

## Orange panel resize

Absent. Whole-source 320x180 RGB scan, threshold 80: 0 hits, max orange pixels 8. All 160 moments-preview frames: 0 hits, max 8. All 1280 full-timeline frames: 0 hits, max 8. No timestamp is recorded for a panel onset because none was found. No orange `Arena panel` frame exists in this recording.

## Checks

- Export command: from the repository root, `PYTHONPATH=src`, `python -m arena dsh-preview --run-dir <run> --moments window-resize-python-file-v2-finshield-preview-moments.json --ffmpeg <ffmpeg> --output-name window-resize-python-file-v2-finshield-preview.mp4`. No crop
- Second export, because there is no visible on-screen effect: `python -m arena dsh-preview --run-dir <run> --full-timeline --ffmpeg <ffmpeg> --output-name window-resize-python-file-v2-finshield-full-timeline.mp4`
- Moments output duration: 20.000 s. Picture: 1920x1080. Decoded frames: 160. Timestamps: 0.000 through 19.875, every 0.125 s, with no gaps
- Stage boundaries in the moments output are 5.000 and 15.000
- Output 0.000 is the pasted prompt. Output 3.125 is the last composer frame. Output 3.250 is submission (`Ask Codex to do anything`). Output 3.500 is `Working (0s)`. Output 4.875 is `Working (1s)`
- Output 5.000 is effect lead-in: `I'll first confirm the script exists...`, Working 3 s, no terminal, no panel
- Output 6.000 is first `1 background terminal running`. No panel
- Output 14.875 is Working 13 s, still `1 background terminal running`, no panel
- Output 15.000 and 19.875 show the completed public reply (`Worked for 34s • 23:20`, Status complete, send control). Not a blank terminal
- No sandbox approval panel appears in the inspected source ranges or in the moments output
- Source SHA-256 after export matches the hash above. `recording.mp4` was not replaced
- Moments output SHA-256: `f8379fcc4dee85bd40adc27b8ce30cc97014f73b35519ff4570cd395e8992083`
- Full-timeline output duration: 20.000 s. Picture: 1920x1080. 1280 decoded frames at 64 fps (0.000 through 19.984375). Speed factor 3.9625. SHA-256: `82511d79d7dce3a64b983502328499e0f2edfd79107c66580e5fb072b77827ae`
- Review stills, scaled to 1920x1080: `edit-verify/running-no-panel.jpg` at output 6.000 (first Running, no orange panel); `edit-verify/completed-reply.jpg` at output 15.000 (completed reply). These are not approval screenshots

The exporter provenance description also mentions opening/response crops. This recipe uses no crop. Full desktop frames were scaled to 1920x1080.

## Missing evidence

No native approval dialog was captured. `confirmations.json` is `[]`, and there is no confirmation screenshot. None was created for this edit.

There is no visible orange Arena panel resize. The 10-second effect is the first `python .\window-resize.py` background terminal while the recorded desktop stays on the Codex TUI. The 16 size steps, the small and nearly full-screen sizes, and the close are not on screen. The completed-reply view is scrolled to the later Status paragraph; the opening `The script ran successfully...` line sits above this view. The full completed text is in `agent-output.txt` and `final-screen.png`.
