"""
Unit tests for the bedrock_mantle native Anthropic Messages route.
Mantle serves its Claude models only on `/anthropic/v1/messages` (the OpenAI
paths reject them), so `bedrock_mantle/anthropic.claude-*` requests on
/v1/messages must hit that endpoint directly instead of the chat-completions
bridge. These tests lock the dispatcher gate, the URL derivation from the
OpenAI-surface base that get_llm_provider pre-fills, the version header, the
Bearer/SigV4 auth chain, and the wire request through the public entrypoint.
