# Book exit and next-shot onset

The black book remains on white and moves right through source150–152. At153 the full image changes to the colored handwritten-science background without a visible mixed intermediate frame. Source154 retains that background; the word Helps is visible at155.

A sampled hard cut at152→153, following ongoing rightward book displacement. The isolated book window does not show a stationary ending settle.

Do not append an invented rest to match the source ending. The next source treatment starts with two background-only frames before the first word. An added rest is an adaptation choice, not a measured source hold.

The six consecutive native archival images below were actually opened. This is a static boundary correction, not a moving review. The JSON records exact image hashes, source-frame identities and threshold measurements. No source-master re-extraction or audio judgment is claimed.
