detection_model kept an empty-string base_model, so base_model: '' in a
deployment's litellm_params disabled the o-series/gpt-5 family and
response_format gates (fail-open: v2 served max_tokens where v1 routes
AzureOpenAIO1Config and emits max_completion_tokens). One-token fix to
'deps.base_model or model'; the docstring's 'exactly like v1' claim is
now true. Pinning corpus row uses base_model='' with the non-prefix
family substring deployment name prod-o3-mini per verifier-azure (the
shared openai prefix gate cannot catch it); row fails without the fix.
