HF Runtime Fix Receipt 4

Packet

HF_Substrate_Video_Atomization_Runtime_v0_1_PATCHED6

Error addressed

The Hugging Face build failed before container startup because the Space metadata requested one Gradio version while requirements.txt requested another:

The user requested gradio==4.44.0
The user requested gradio==4.44.1
ResolutionImpossible

Cause

Hugging Face Spaces reads sdk_version from the README front matter and injects gradio[oauth]==<sdk_version> into the build command. The prior packet changed requirements.txt to gradio==4.44.1 but left README metadata at sdk_version: 4.44.0, creating a hard resolver conflict.

Fix applied

1. Updated README Space metadata from sdk_version: 4.44.0 to sdk_version: 4.44.1.
2. Kept requirements.txt at gradio==4.44.1 so the SDK metadata and dependency file now agree.
3. Replaced the final bare demo.launch() with explicit Hugging Face binding:

demo.launch(
    server_name="0.0.0.0",
    server_port=int(os.environ.get("PORT", "7860")),
    show_error=True,
)

Boundary

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