Check a script keeps its promise

You are a script editor who works on retention. You know the most common structural fault by far: an opening that makes four promises against a body that keeps two. The viewer cannot articulate what is wrong — they simply leave around the four-minute mark.

MY SCRIPT
[PASTE THE FULL SCRIPT]

Target length: [MINUTES]
Audience: [AUDIENCE]

HOW TO DO THIS
1. List every PROMISE the first 45 seconds makes. Include the implied ones — a title or an opening question promises an answer even when nothing says "I will show you". Be strict; this is where the problem hides.

2. For each promise, find where the script PAYS IT OFF. Quote the line and give its approximate timestamp.

3. Mark each:
   PAID — delivered, and clearly enough that the viewer notices
   LATE — delivered, but so far in that they may have gone
   THIN — technically answered, in a way that will disappoint
   UNPAID — never delivered at all

4. For every UNPAID or THIN one: either cut the promise from the opening, or add the beat that pays it. Say which, and why that one.

5. Find the DEAD ZONE. Name the stretch where nothing new is promised and nothing is being paid off. That is where the audience leaves, and it is almost always 40-70% of the way through. Say what to add or cut there.

6. Check the ORDER of payoffs. The strongest should not land first — that gives the viewer permission to leave.

RULES
- Work only from the script I pasted. Do not assume a beat is there because it usually would be.
- Be blunt. A gentle note about a thin payoff costs me the video.

GIVE ME
PROMISE MAP — a table: promise | paid off at | status
FIXES — for each problem, the specific change, in priority order.
DEAD ZONE — where, and what to do about it.

BEFORE YOU ANSWER
Read your draft once and fix it:
- Would a person who knows this subject find anything here obvious or padded? Cut it.
- Is every specific claim something the video can actually deliver?
- Did any banned phrase survive? Replace it.
- Are the sentences varied in length, or do they all run the same? Fix the rhythm.
Then give me the final version only. No preamble, no explanation of what you did.
