📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes

  • Improved Hugging Face endpoint configuration when the HF_ENDPOINT setting is empty.
  • The default Hugging Face service is now used reliably when no valid endpoint is provided.
  • Trailing slashes in configured endpoints continue to be handled correctly.

• Tests

  • Added coverage for empty endpoint configuration scenarios.

Walkthrough

HF_ENDPOINT now falls back to the default Hugging Face registry when unset or empty after trimming trailing slashes. Unit and end-to-end test handling reflects this behavior.

Poem

I’m a bunny with an endpoint to mend,
Empty strings now reach the proper end.
Trim the slash, restore the way,
Tests hop in to guard the day.
