HF Runtime Fix Receipt 3

Packet

HF_Substrate_Video_Atomization_Runtime_v0_1_PATCHED5

Error addressed

The Hugging Face Space started, then crashed while Gradio generated API metadata:

• TypeError: argument of type 'bool' is not iterable
• ValueError: When localhost is not accessible, a shareable link must be created.

Cause

The primary fault was a Gradio / gradio_client API-schema generation mismatch. Gradio attempted to convert a JSON schema fragment where additionalProperties was boolean. The gradio_client converter expected a dict-like schema and crashed.

The localhost/share error was downstream: because the root route failed during startup/API-info generation, Gradio concluded localhost was inaccessible.

Fix applied

1. Added a narrow compatibility guard in app.py that maps boolean JSON-schema fragments to Any during Gradio API metadata conversion.
2. Changed launch call to bind explicitly for Hugging Face Spaces:
   • server_name="0.0.0.0"
   • server_port=int(os.environ.get("PORT", "7860"))
   • show_error=True
3. Updated Gradio pin from 4.44.0 to 4.44.1 while preserving huggingface_hub==0.25.2 to keep the previous HfFolder fix settled.
4. Removed transient __pycache__ from the release packet.

Boundary

No atomization logic, HIR/OAM receipt logic, frame sampling, hashing, OpenCV processing, trace-stack construction, or packet generation logic was changed.
