fix(router): mirror last-wins for stripped/wildcard dict fallback resolution 
_resolve_dict_fallback_targets returned the first stripped or wildcard match,
but get_fallback_model_group keeps overwriting and uses the last match in each
of those tiers. With duplicate stripped keys (or wildcards), the runtime
fallback hop calls the last target while the capability scan only saw the
first, so a Sonnet 4.6+ deployment hidden behind a prefill-supporting first
hit was never detected and the mid-stream resume still sent assistant prefill
and got a 400.

Mirror the helper's per-tier semantics: exact still first-wins-and-breaks;
stripped and wildcard now pick the last match in their tier.

Testing for litellm/

This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.

The point of this is to:

  1. Increase test coverage of litellm/
  2. Make it easy for contributors to add tests for the litellm/ package and easily run tests without needing LLM API keys.

File name conventions

  • litellm/proxy/test_caching_routes.py maps to litellm/proxy/caching_routes.py
  • test_<filename>.py maps to litellm/<filename>.py
