|
| ## 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. |
