# MiniMax H3 connector prompt: insert one aligned plug into a fixed port

Advance an already aligned connector into a fixed socket, then stop seated. The changing visible insertion depth is the task; no electrical behavior or device activation is requested.

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 original side-view illustration shows a rounded teal socket block, a pale recess and an orange connector facing the recess from the left. A cable continues out of the connector body. This is a fictional low-detail prop, not a named connector standard.

Track the port centerline, the exposed connector tip and the junction between cable and body. The socket block must not travel toward the plug to fake insertion.

## Steps

1. Check that the first frame already shows a clear gap and compatible visual alignment. Correct an unsuitable source image rather than asking a hidden rotation and an insertion to happen together.
2. Keep the port and camera fixed. Ask for one approach and seat, without claiming a click, charging result or standards compliance.
3. Inspect the last visible tip, the seated boundary and the cable attachment. A disappearing tip is only useful when it enters the actual recess and the body retains its size.

## Acceptance

- The port block and its centerline remain stationary.
- The exposed tip shortens at the recess as the connector body advances without shrinking.
- The cable stays connected to the same connector body.
- The ending is a seated connector with no invented activation or second port.

## Limits

This visual exercise neither identifies an actual connector standard nor verifies safe electrical connection, charging or power transfer.
