+# 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.

 ## Runtime compatibility patch 3
 
 This packet removes `type="filepath"` from the `gr.Video(...)` upload component because Gradio 4.44.x rejects that keyword on `Video.__init__`. The callback still receives the uploaded video path, so the source-bound atomization route is unchanged.

+## Social card / X preview
+
+This packet includes `assets/social_card.png` and declares it in the Space README front matter as:
+
+```yaml

+
+The image is a 1200 × 630 social-card render for link preview surfaces. It is display metadata only; it does not alter runtime atomization, trace stack, receipt, preview, or packet logic.
