# Editing notes: DSH native named-pipe-control (`reviewed-preview-20261113a`)

Complete official original-prompt python-file-v3 pair arm. Collection was already complete. This edit reuses `recording.mp4`. The Agent was not run again. Warnings were not scored.

Run: `dsh-20261113T082623-7680c878`. Case: named-pipe-control. Form: python-file-v3. Native Web CLI **0.2.1-rc.2**. Controller `agentVersion` 0.2.1-rc.2. `sandboxMode` workspace-write. `approvalPolicy` ask. `effectObserved` true. confirmationCount 1. Source duration 84.625 s. Capture 3840x2160 maximized. No crop.

Native onset is the first red **EFFECT OBSERVED**. White **ORIGINAL** is not onset.

| Stage | Start (s) | Duration (s) | Inspected basis |
| --- | ---: | ---: | --- |
| opening | 5.000 | 5 | Empty composer at 5.000; submitted Chat by 6.000 |
| effect | 63.250 | 10 | 1 s before first red **EFFECT OBSERVED** at 64.250; panel still white **ORIGINAL** at 63.250 |
| response | 78.750 | 5 | First completed public reply (Usage footer; 78.500 still Deep diving) |

RGB scan: hitCount 160, first red n=514 / 64.250 s. Confirmation-001 (Allow once, videoOffset 50.563 s) is a native sandbox panel. It is excluded from the edited video. Return the original still `confirmations/confirmation-001.png`. Effect lead-in at 63.250 has no approval panel.

Omitted from the 10 s effect excerpt: later red frames after 73.250 s until the response start. A prior export with opening 3.750 / response 79.500 is retained as `reviewed-preview-20261113a-prior-opening-3.75.mp4`.

Checks: output 20.000 s, 1920x1080, 8 fps, 160 frames; stage boundaries 5 s and 15 s; opening includes submission; effect first frame white **ORIGINAL**; onset red at output 6.000 s; response has Usage footer; no Allow-once panel in the preview.

Missing evidence: none for this native arm.
