ffprobe reports H.264, 1920x1080, 30/1 fps, and 120.000 s. Build and runtime provenance are recorded in build.txt, integration-build.txt, and inspection.txt. The inspection log reports the compositor seed and removal messages with commit_seq=6; those logs are not used here as proof of physical display continuity.

Method

I reviewed the full recording at 5-second cadence:

ffmpeg -y -hide_banner -loglevel error \
  -i docs/evidence/splash-initial-scene-ready/20260922T222835Z-initial-scene-panel-ready-boot.mp4 \
  -vf 'fps=1/5,scale=480:-1,tile=5x5' -frames:v 1 /tmp/ready-audit/broad.jpg

The handoff was sampled at 5 fps over 68.0–77.8 s, 10 fps over 72.0–73.9 s, and 10 fps over 72.5–73.4 s:

ffmpeg -y -hide_banner -loglevel error -ss 68 -t 10 \
  -i docs/evidence/splash-initial-scene-ready/20260922T222835Z-initial-scene-panel-ready-boot.mp4 \
  -vf 'fps=5,scale=320:-1,tile=10x5' -frames:v 1 /tmp/ready-audit/transition.jpg
ffmpeg -y -hide_banner -loglevel error -ss 72 -t 2 \
  -i docs/evidence/splash-initial-scene-ready/20260922T222835Z-initial-scene-panel-ready-boot.mp4 \
  -vf 'fps=10,scale=480:-1,tile=10x2' -frames:v 1 /tmp/ready-audit/fine.jpg
ffmpeg -y -hide_banner -loglevel error -ss 72.5 -t 1 \
  -i docs/evidence/splash-initial-scene-ready/20260922T222835Z-initial-scene-panel-ready-boot.mp4 \
  -vf 'fps=10,scale=960:-1' -frames:v 1 panel-ready-transition.png
ffmpeg -y -hide_banner -loglevel error -ss 88 -t 1 \
  -i docs/evidence/splash-initial-scene-ready/20260922T222835Z-initial-scene-panel-ready-boot.mp4 \
  -vf 'fps=1,scale=960:-1' -frames:v 1 panel-ready-shell.png

Observations

The initial K230 scene remains visible in the broad samples through about 72.5 s. In the dense sequence, the logo is visible at approximately 72.5 and 72.6 s; the first shell top-bar pixels appear around 72.7 s, with the shell clearly established by about 72.8–72.9 s. No dark camera frame was observed around this handoff. The camera therefore brackets the visible change at roughly 72.6–72.7 s and again does not reproduce the earlier 1.1–1.2 s dark interval from the first preserve-image trial.

The handoff still has camera-frame limits: it cannot exclude a sub-frame or exposure transition and does not prove uninterrupted electrical scanout. The physical panel is oblique and reflective. The extracted initial-scene frame (SHA-256 15d4fdc1a82bae8c09d97218ba0ff9484480e969dd65d757e648342b5e8804a6) shows the lower-panel K230 scene; shell frame (SHA-256 d093fcf3768834ef40205f558e17832bf22d0404de0451b5430239377ed8690d) shows the first Linux portrait shell bar and terminal.

The shell is visibly in the expected portrait orientation, without an obvious horizontal wrap or magenta color swap in these frames. This is a visual observation rather than calibrated geometry or color evidence. It does not establish battery-only boot, real-finger input, or that the result generalizes beyond this captured boot; the runtime seed/remove log and the camera recording are evidence from the same trial, not independent proof of physical continuity.
