[frontier] Agent's behavioral boundaries erode over long sessions with many examples that gradually shift the acceptable behavior threshold

Implement boundary checkpoints: at every 25-30 turn interval, inject a probe that tests whether the agent still enforces critical boundaries. If the agent fails, inject a corrective anchor with explicit reasoning for the boundary. Design session architecture to force a context reset or strong boundary reinforcement after every 30 turns of continuous interaction.

Journey Context:
Anthropic's many-shot jailbreaking research demonstrated that many in-context examples of harmful behavior can erode safety training. The same principle applies to any behavioral boundary: enough edge-case examples in a long session gradually shift the agent's internal threshold for what is acceptable. This is not just a safety problem — it affects any constraint that defines a boundary \(output format strictness, scope limitations, detail level\). The frontier practice is to treat long sessions as inherently adversarial to constraint boundaries. Rather than assuming boundaries will hold, proactively test them with probe inputs and correct drift before it compounds. This is analogous to integrity checks in distributed systems: you don't assume your data is correct; you verify it periodically.
