X Card Deployment Checklist — False Closure / Open Loop Simulator

Use this exact public page URL when posting to X:

https://huggingface.co/spaces/HirModel/false-closure-open-loop-simulator

If X keeps showing an old/default card, use this cache-busting version in the post instead. It still opens the same HF Space:

https://huggingface.co/spaces/HirModel/false-closure-open-loop-simulator?v=014-card

Do not attach the thumbnail image manually to the X post if you want the image itself to behave as the clickable link card. Paste the HF link and let X render the card preview in the composer.

Files that must be committed to the Space root:

• README.md
• index.html
• thumbnail.png
• false-closure-open-loop-thumbnail-v0-1-4.png

Root README frontmatter must contain:

thumbnail: https://huggingface.co/spaces/HirModel/false-closure-open-loop-simulator/resolve/main/false-closure-open-loop-thumbnail-v0-1-4.png

After upload, open the thumbnail URL directly in a private/incognito browser tab. If it loads publicly, X can fetch it.
