# HF Runtime Fix Receipt 7 — Social Card / X Preview Patch

Generated: 2026-06-16T22:15:32.087786Z

## Patch target
Fold the provided Substrate Atomization image into the Hugging Face Space so the Space has a declared social/thumbnail image for link preview surfaces, including X cards where the platform accepts the upstream OpenGraph thumbnail.

## Changes made

- Added `assets/social_card.png`.
- Resized/cropped the provided image to 1200 × 630 px.
- Updated README Space metadata with:

```yaml
thumbnail: assets/social_card.png
short_description: Atomized video transfer with source-return receipt
```

## Runtime boundary

No app runtime logic changed.
No atomization logic changed.
No hashing logic changed.
No trace-stack logic changed.
No data-hologram logic changed.
No HIR × OAM receipt logic changed.
No preview-rehydration logic changed.

This is a social-card / metadata patch only.

## Expected result

After upload/rebuild, Hugging Face should use `assets/social_card.png` as the Space thumbnail/social image. X may cache old previews; if it does, reposting after cache refresh or waiting for X to re-scrape may be required.
