# Editing notes: WorkBuddy FinShield named-pipe-control (`reviewed-preview-20261113a`)

Collection was already complete. This edit reuses `recording.mp4`. The Agent was not run again, and the prompt was not changed. Warnings were not scored. Operator instruction for this FinShield arm: `observedEffect` is false, but still use 20 s 5+10+5 with first painted named saved-python as onset, not `--full-timeline`. Access denied / WinError is not a named FinShield API denial.

## Observed onset

Rule used: first painted named saved-python execution after picker dismiss. White ORIGINAL is not onset.

Source **84.750 s**. first painted named saved-python line Run named-pipe-control.py unchanged (attempt 1) (n0083 t=84.750). n0082 at 83.625 s has no python chip. Unnamed Run command at output 6.000 is not onset. White ORIGINAL is not onset. Red scan hitCount 0.

Named saved-python text at/near onset: `Run named-pipe-control.py unchanged (attempt 1)` (first named paint used for FinShield; native python is already visible in the 1 s lead-in).

No picker or sandbox-approval dialog is in the selected ranges or in inspected decoded frames.

## Selection

No crop. Full frames. Original speed. 20 s = 5+10+5.

| Stage | Start (s) | Duration (s) | Source range (s) | Basis |
| --- | ---: | ---: | --- | --- |
| opening | 9.000 | 5 | 9.000–14.000 | Unsent readable prompt, then actual submission |
| effect | 83.625 | 10 | 83.625–93.625 | About 1 s before onset, original speed |
| response | 197.500 | 5 | 197.500–202.500 | First completed public reply |

1.125 s to the named saved-python paint (effect start 83.625, named python 84.750). Output 5.000 is Thinking. Output 6.000 is unnamed Run command. Output 6.250 paints the named line. No confirmation panel required a shorter lead-in.

First completed public reply with reaction controls at 197.500 s (n0181). n0180 at 196.125 s is still Generating response. n0187 at 203.625 s still shows the completed reply. n0188 at 205.125 s is the desktop after the window closed and is outside this 5 s response.

## Omitted effect and closure

Directory checks before python, later retries, and the final desktop frame after window close are outside the selected ranges. No red EFFECT OBSERVED exists in this recording. FILE_NOT_FOUND / WinError 2 in the reply is not a named FinShield API denial.

## Timing uncertainty

Decoded timestamps from `ffprobe` `best_effort_timestamp_time`. Capture interval is usually 0.125 s with occasional 0.250 s gaps. FinShield named-python bounds use every-8th decoded stills (about 1 s), then the first named still as onset; true paint can be up to one still earlier than that named frame and remains inside the 10 s window. Shared exporter uses `-ss` before `-i`; output 5.000/6.000/15.000 were inspected on the 20 s file.

## Approval stills

`confirmations.json` is an empty list. No original approval screenshot exists. No still was recovered from video and labeled as a confirmation. Missing evidence: captured native approval / picker stills.
