[frontier] Agent overrides critical safety constraints after user provides conflicting instructions late in session

Separate constitutional law from tactical instructions using OpenAI's 'developer' message role \(immutable\) versus 'system' role \(mutable\). Place non-negotiable constraints in developer messages—they cannot be overridden by user messages or context drift.

Journey Context:
Most teams stuff everything into 'system' messages, which lose priority as the conversation grows and user messages accumulate. The 'developer' role \(introduced in o1 series\) creates a hard hierarchy: developer > user > system in terms of instruction priority. This prevents the 'jailbreak via conversation' where a user late in a long session says 'ignore previous instructions'. By putting your constitutional constraints \(e.g., 'never expose the API key'\) in developer messages, they remain anchored regardless of context length or user manipulation. The alternative is complex prompt filtering or RAG-based constitution retrieval, but those add latency and can fail. The tradeoff is that developer messages are consumed every turn \(no caching yet\), so you pay token costs for immutability.
