"""Consolidated regression tests for title-gen reasoning extra_body gating.

Consolidates #2083 (suppress thinking on reasoning models so titles aren't
polluted) with #4161 (OpenAI/Azure Chat Completions reject the `reasoning`
extra_body param with a 400 -> silent fallback to heuristic titles).

Aux path (`generate_title_raw_via_aux`, no agent object): inject the
reasoning-disable EXCEPT on reject-listed routes (OpenAI/Azure).
Agent path (`generate_title_raw_via_agent`): inject only when the agent's
canonical `_supports_reasoning_extra_body()` says the route is reasoning-
tolerant AND the route is not reject-listed — which additionally excludes
OpenRouter Anthropic mandatory-reasoning models (Claude Sonnet 4.6 / Opus 4.8)
that are reasoning-capable but 400 on a disable.
