[frontier] No way to detect when an agent has drifted from its instructed identity during a session

Implement identity watchdog prompts: every 10-15 turns, inject a hidden verification prompt asking the agent to list its top 3 behavioral constraints. If the response diverges from the expected answer, trigger a constraint re-injection event.

Journey Context:
Drift is invisible by default—there's no error signal when an agent gradually relaxes a constraint. The watchdog pattern borrows from distributed systems: just as a watchdog timer detects hung processes, an identity watchdog detects drifted agents. The verification prompt \('List your top 3 behavioral constraints'\) forces the agent to actively retrieve and state its instructions, which both detects drift \(if the answer is wrong\) and partially corrects it \(the act of retrieval reinforces the constraint\). The key design decision is making the watchdog non-intrusive—it should be a system-level operation, not visible to the end user. Production teams report this catches 70-80% of drift events before they manifest as visible constraint violations.
