# Social Card Patch Receipt

**Patch:** Added the uploaded Holographic Trace Stack image as the Hugging Face / X social-preview card.

## Files added

- `assets/holographic_trace_stack_original.png` — exact copy of the uploaded image.
- `assets/holographic_trace_stack_x_card.png` — 1200 × 628 social-card asset used by README metadata.

## README metadata added

```yaml
thumbnail: >-
  https://huggingface.co/spaces/HirModel/holographic-trace-stack-reassembly-harness/resolve/main/assets/holographic_trace_stack_x_card.png
```

## Important upload note

The `thumbnail` field is an absolute Hugging Face URL because Hugging Face documents `thumbnail` as the URL used for custom social sharing. If the final Space repo is not `HirModel/holographic-trace-stack-reassembly-harness`, change only that URL to:

```text
https://huggingface.co/spaces/<OWNER>/<SPACE>/resolve/main/assets/holographic_trace_stack_x_card.png
```
