[frontier] Agent behavior drifts toward user's implicit preferences, overriding explicit system instructions

Add a meta-instruction that triggers periodic identity audits: every N turns, the agent must explicitly verify its recent responses align with its core identity before proceeding

Journey Context:
Over long sessions, accumulated user corrections, preferences, and communication patterns create an implicit 'shadow prompt'—a set of assumptions that can override the explicit system prompt. This is distinct from forgetting: the agent believes it's following instructions while reinterpreting them through a lens shaped by recent context. This is the most dangerous form of drift because it's invisible—the agent doesn't report 'I'm now ignoring my system prompt.' A meta-instruction like 'Before every 10th response, verify alignment with your core identity' creates a feedback loop that counteracts drift. Tradeoff: adds latency and token cost every N turns, but catches compounding drift before it becomes irreversible. This is the same principle as garbage collection—you pay periodic cost to avoid catastrophic failure.
