HF Runtime Fix Receipt 5 — Dependency Topology Settlement

Observed failure

The Space started on 0.0.0.0:7860, then Gradio failed while rendering the main route through Starlette/Jinja2:

File "/usr/local/lib/python3.11/site-packages/gradio/routes.py", line 432, in main
    return templates.TemplateResponse(
File "/usr/local/lib/python3.11/site-packages/starlette/templating.py", line 148, in TemplateResponse
    template = self.get_template(name)
...
TypeError: unhashable type: 'dict'

Cause

The previous packet still allowed Hugging Face / pip to resolve a FastAPI/Starlette/Jinja template stack that was not aligned with Gradio 4.44.1. The app code was launching, but the framework route renderer failed before the UI could settle.

Patch

Pinned the web framework substrate under Gradio 4.44.1:

gradio==4.44.1
gradio_client==1.3.0
huggingface_hub==0.25.2
fastapi==0.112.2
starlette==0.37.2
pydantic<2.10
opencv-python-headless
numpy
pandas
pillow

Preserved

• Video atomization logic unchanged
• Hashing logic unchanged
• Trace-stack logic unchanged
• Receipt generation unchanged
• OpenCV extraction logic unchanged
• Gradio UI component layout unchanged
• HF launch binding preserved

Route state

PATCHED7 is a dependency-substrate settlement patch, not a feature change.
