Hugging Face Docker Space Deployment Steps — v3.3.1

1. Create a new Hugging Face Space.
2. Choose Docker as the SDK.
3. Keep it private for first testing.
4. Upload the extracted contents of this packet to the repository root.
5. Add Space secret:

SUBSTRATE_ACTION_KEY=<long random secret>

6. Build the Space.
7. Open:

https://YOUR-HF-SPACE.hf.space/v1/mesh/health

8. Confirm status is HELD and auth_configured is true.
9. Test /v1/mesh/command with the same Bearer token.
10. Only after that, connect GPT Actions.

Do not place the bearer token in README, Knowledge files, OpenAPI YAML, or public code.
