Report #79918

[frontier] Agent gradually reinterprets 'never do X' as 'prefer not to do X' over extended sessions

Deploy Constitutional AI critique loops: freeze the original system prompt as a 'constitution', then use a separate critique model instance to evaluate agent outputs against this frozen baseline every N turns

Journey Context:
Instruction entropy accumulates because language models treat repeated instructions as 'softening' evidence. Simple string matching fails to catch semantic drift. Constitutional AI provides a frozen reference frame. The critique model detects when 'never' has drifted to 'rarely' even when the agent's own state claims compliance.
