 `--model <name>` accepts only the values above; any other slug is refused at startup with the supported list. The same whitelist drives the inline `/model` picker, so the two surfaces never disagree about which models exist.

 Provider mapping:
 
 - **OpenAI** sends `reasoning.effort`; `off` maps to minimal reasoning and suppresses reasoning summaries.
-- **Claude Fable 5, Opus 4.7, and Sonnet 4.6** use adaptive thinking. The provider chooses the token budget from the effort level.
+- **Claude Fable 5, Opus 4.8, and Sonnet 4.6** use adaptive thinking. The provider chooses the token budget from the effort level.
 - **Claude Haiku 4.5** uses fixed legacy thinking budgets for `low`, `medium`, and `high`. `off` disables extended thinking.
