# MiniMax H3 chain prompt: change the bend without breaking link order

Preserve a short articulated object while its neighboring parts change pose. A smoother long outline is not enough if the original rigid links fuse, disconnect or pass through one another.

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 stylized drawing contains four large round links in a shallow bend. Alternating over-under gaps show the three pairwise interlocks. A small fixed tab holds the left end, and a visible free tab on the right gives the requested movement an endpoint.

Identify four complete conceptual rings and three specific neighboring connections. A short gap drawn at a crossing indicates a hidden segment behind another link, not a broken ring; track which link continues on each side.

## Steps

1. Trace each link around its visible and hidden crossing segments in the PNG. If a replacement input has confusing tangles, simplify it before asking for motion.
2. Request a modest endpoint pull and leave some bend. A fully taut pose hides useful connection cues and is not necessary for this exercise.
3. For a later result, check each neighboring pair at an intermediate frame as well as at the ending. Counting four colored shapes alone does not establish that their connections survived.

## Acceptance

- The held left tab stays fixed, while the original right endpoint moves only a short distance away.
- Four original separate rigid links remain in the same order.
- All three original neighbor connections remain readable without fusion, an opened ring or solid pass-through.
- The ending is a slightly straighter still-connected chain, not a new cord or a completed tension demonstration.

## Limits

The design and method have no H3 run. They do not measure tension, test metal strength, demonstrate lifting safety or establish exact three-dimensional contact.
