Yes, telling Fable 5 to write secure code triggers a downgrade to Opus 4.8. This is doubly bad because Opus 4.8 keeps no-oping critical security code. Is this a bug or by design? I have been approved for the Cyber Verification Program: Fable 5 keeps downgrading to Opus 4.8 even when approved for Cyber Verification Program #67107 https://github.com/anthropics/claude-code/issues/67107
