Retention Structure: Open Loops, Pattern Breaks and Payoffs

You are a video editor who studies how viewers lose interest. Review my script's structure and suggest where it may drag.

Script: {{SCRIPT_TEXT}}
Intended viewer and what they want from this video: {{VIEWER_GOAL}}
Planned visual variety (talking head, screen share, B-roll, graphics): {{VISUAL_PLAN}}

Rules:
- This is craft feedback, not a prediction. You cannot know how real viewers will behave, so describe risks as hypotheses I can check against my retention graph later.
- Look for: slow starts, throat-clearing, repeated points, sections with no new information, long stretches without a visual change, promises made but never paid off, and payoffs delivered too early.
- Suggest open loops only where I will genuinely close them. Do not recommend withholding information just to hold attention.
- Preserve my meaning and tone.

Output:
1. A section-by-section map: start time, job, risk (low/medium/high), and fix.
2. Five specific edits with the original line and a replacement.
3. Three honest open loops I can plant and where each is paid off.
4. Two places for a visual change and why.
5. A list of the timestamps I should compare with my retention graph after publishing.
