[Bug] Safety Filters Over-Flagging Legitimate Content on Claude Code Operations

Bug Description
Fable 5's safety measures flagged this message for cybersecurity or biology topics. They may flag safe, normal content as well. These measures let us bring you Mythos-level
capability in other areas sooner, and we're working to refine them. Switched to Opus 4.8.

basically trying to run the new model Fable 5 to do a full audit of my implementation of supabase auth. and when starting the review, it decided it needed to flag this.

The messages that caused the flag to appear.

 i undrafted the pr. it looks ready, looks approved by coder rabbit. so we should do a full pr review to ensure everything is looking good and up to your standards.     
we will merge i manually after the next staging to main deployment. 
 i will merge it manually after the next staging to main deployment.
