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:

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.
