This no-op test uses structural equality, so it also passes when the adapter allocates and returns an identical copy of the request. The implementation returns the original request when no legacy reasoning content needs adaptation; use require.Same(t, req, adapted) (or assert.Same) so an unnecessary-copy regression is caught. This is a non-blocking test-coverage concern, but retaining the pointer assertion avoids silently changing the no-op contract.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
Artifacts
- The exact temporary in-package Go test was saved before removal; it checks the real no-op pointer plus the deep-equality-versus-identity distinction, proving the required assertion semantics.
- The original focused vLLM test command completed successfully with exit code 0, showing the current structural assertion passes but not establishing pointer identity.
- The authored focused Go test completed successfully with exit code 0, proving the current no-op implementation returns the original request pointer and that the stronger assertion is executable.
- Captured numbered source evidence shows the deep-equality assertion, the implementation’s conditional copy and `return req`, and that DeepSeek and MiniMax tests are included in this commit’s changed diff, confirming the candidate.

Assert the injected transport error.
Line 233 accepts any error. The test can pass even if ChatCompletion returns an unrelated error before the transport executes. Use require.ErrorIs to verify propagation of errTransport.
Proposed fix
- require.Error(t, err)
+ require.ErrorIs(t, err, errTransport)As per coding guidelines, “Tests should cover request translation, response normalization, error handling, default configuration, and provider-specific parameter mapping.”

Restore Kilo ListModels coverage for provider-qualified IDs.
Kilo delegates ListModels to openai.CompatibleProvider, while the shared ModelsJSON fixture uses the slash-free "test-model". Existing slash-containing tests cover chat requests, not model-list responses. Add a Kilo ListModels test that serves google/gemini-3.1-pro and asserts the ID is returned unchanged.

The per-package copies of those tests are removed; provider-specific tests (headers, reasoning mapping, model ID rewriting, audio, images, realtime, error mapping) stay./responses(oracle, sglang, vllm, llamacpp, llmd, openrouter, xai) and the azure and bedrockmantle adapters keep their own tests and are noted in the report.var _declarations.
