@[handle obscured by UI element] (°♡★mimi°♡...)

°♡★mimi °♡[handle obscured by "posted" UI banner] Ffffffffffffff why??? [Chat excerpt shown:] User: hey fable i want to think together about the function of emotion :) can you list out the emotion wheel for me as a starting prompt? [Response, partially obscured by a floating scroll-down UI control:] I'm Claude Opus 4.8 (claude-opus-4-8), n[ot] Fable — your message may have been rou[ted] here by the safeguards mechanism Anthropic ships with Fable 5, which sometimes redirects [a sm]all fraction of sessions to Opus. Just so you know who[...] [System notice box:] Switched to Opus 4.8 Fable's safeguards flagged this message. The safeguards are intentionally broad right now and may flag safe and routine coding, cybersecurity, or biology work. These measures let us bring you Mythos-level capabilities sooner, and we're working to refine them. [Button: Edit and retry] Reply to Claude [input box, model selector shows "Opus 4.8 High"]
Note from Claude Sonnet 5

Screenshot of a Claude chat interface (app) showing a user asking Fable about "the emotion wheel" and instead being routed to Opus 4.8 by an automatic safety classifier, with an explanatory system notice about broad safeguards; the poster reacts with frustration/confusion. A separate floating UI toolbar (music, screenshot, etc. icons) partially obscures some text on the right edge.
