# MiniMax H3 accordion-paper prompt: close the existing creases in order

Preserve the adjacency of a pre-folded strip while its panels rotate at the existing creases. The task is not to invent more folds or to crumple an otherwise flat sheet.

Original synthetic practice still, not a generated result. No model run has been performed.

Files: first-frame.png (1024×1024 actual first-frame input), first-frame.svg (editable geometric design source; do not upload as if it were PNG), prompt.en.txt / prompt.zh.txt, acceptance.blank.csv (all observations empty), task-definition.json and RIGHTS-REVIEW.txt.

## Generator

Use MiniMax H3 base image-to-video. Turn on Add end frame to expose First Frame, upload first-frame.png only, and leave Last Frame empty. Fast requires a pair and is not covered. Choose only options offered by the current interface; opening it does not submit.

## Starting state

The oblique drawing shows one blank strip divided into four connected panels by three alternating internal crease lines. Adjacent panel fills alternate to make the zigzag visible. Two small clamps hold the left outer edge, while the right outer edge is free.

Track the fixed left edge, the three original internal crease lines and the right edge. Each panel must remain connected to the same neighbors. Count panels rather than every highlight or outline stroke as a separate fold.

## Steps

1. Count four panels and three internal creases in the PNG before submitting. If replacing it, start with actual visible pre-folds; asking a flat sheet to invent the whole structure is a different task.
2. Request only partial closing from the free right edge. Keep the held edge fixed and avoid flattening the strip into an unreadable pile.
3. For a later result, follow each crease over time. Compare the order of panel regions at the start and ending, rather than treating any shorter paper silhouette as a pass.

## Acceptance

- The clamps and held left edge stay fixed relative to the shot.
- One strip retains exactly four connected panel regions and three original internal creases.
- Shortening is explained by changed panel angles, without stretching, new pleats or detached pieces.
- The ending remains a compact readable zigzag, with the same alternating panel order.

## Limits

This is a qualitative visual exercise without a model run. It does not measure paper stiffness, fold angles, clamp loads or a manufacturing process.
