What's wrong with this entry?
The model-switch notification now distinguishes between general content flags and domain-specific ones. When a domain is known, the message reads:
> "[Model] has specific safety measures that flag messages with cybersecurity topics. Switched to [other model]. …"
For general flags: "[Model] has specific safety measures that flagged something in this message. This sometimes happens with safe, normal conversations."
The switchModelsOnFlag setting description has also been clarified from "When safety filters block a message" to "When safety measures flag a message", and the consequence updated from "your chat may stop" to "your session will pause instead".
Domain-specific safety message builder (search for "has specific safety measures that flag messages with")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
