 Each tier can be pointed at any Claude model via `ANTHROPIC_SMALL_MODEL` / `ANTHROPIC_MEDIUM_MODEL` / `ANTHROPIC_LARGE_MODEL` (or the setup wizard). If you set a tier to `claude-fable-5`, note that Fable's safety classifiers route cybersecurity tasks to Opus 4.8, so those phases run on Opus 4.8 regardless.
