"""
Test that server_tool_use (srvtoolu_) is reconstructed as server_tool_use.
Test that a server tool call (srvtoolu_) with no stored result is replayed
as a regular tool_use block.
Fixes: https://github.com/BerriAI/litellm/issues/17737
A server_tool_use block is only valid when paired with its result block, so
an unpaired one must degrade to tool_use for Anthropic to accept the replay.
A paired call still becomes server_tool_use, covered by
test_convert_to_anthropic_tool_invoke_with_web_search_results.
Context: https://github.com/BerriAI/litellm/issues/17737 (original
server_tool_use reconstruction) and LIT-6622 / PR #39144 (unpaired calls
degrade instead of 400ing at Anthropic).
