"""Tests for Arcee Trinity Large Thinking per-model overrides.

Arcee Trinity Large Thinking is a reasoning model that wants:
- Fixed temperature=0.5 (vs the global default)
- Compression threshold=0.75 (delay compression to preserve reasoning context)

The helpers must match the bare model name, including when it arrives via
OpenRouter as ``arcee-ai/trinity-large-thinking``, but must NOT hit sibling
Arcee models like trinity-large-preview or trinity-mini.
