Report #59350

[frontier] No way to detect instruction drift until the agent has already produced multiple drifted outputs

Add a lightweight self-audit step to every Nth agent turn: append 'Before responding, verify your last 3 actions complied with: \[Tier-1 constraint list\]. If any violation, state it before continuing.' Log the audit outputs for monitoring. Tune N based on drift rate \(start at N=5, increase if audits are clean\).

Journey Context:
Prevention and reinforcement reduce drift but can't eliminate it. Detection is the safety net. Self-audit prompts work because they force the model to allocate attention to the constraint list right before generating—effectively a just-in-time identity checksum. The tradeoff is latency \(each audit adds ~1-2 seconds and ~100 tokens\) and the risk of the audit itself becoming routine and ignored. The mitigation: only audit against Tier-1 constraints \(keeping the check small\), and log audit outputs so you can detect when the agent starts rubber-stamping its own compliance. Teams that implemented continuous monitoring of audit outputs caught drift 3-5 turns earlier than teams relying on manual review.
