## Flags

- **[medium · inference] SambaNova ships raw chain-of-thought as the answer when truncation lands mid-thought** - With thinking on, a max_tokens cut that lands inside the thought returns the entire raw thought channel - literal template marker included - in the content field, with the reasoning field empty and no answer at all. Deterministic, three of three identical runs; a cut landing mid-answer splits cleanly, so only the mid-thought cut leaks.
