[frontier] Catastrophic forgetting of negative constraints in long contexts

Apply constraint rehearsal scheduling: every N turns \(where N = context\_length / 10\), explicitly query the agent to list all 'forbidden' actions and verify against a golden constraint list; use spaced repetition algorithms to optimize rehearsal intervals.

Journey Context:
Agents excel at remembering capabilities \(what they CAN do\) but suffer catastrophic forgetting of constraints \(what they MUST NOT do\) as context grows. This asymmetry arises because capabilities are reinforced by usage while constraints are only tested by violation. Simple 'remember the rules' reminders suffer from the spacing effect—too frequent and they get ignored, too sparse and forgetting occurs. The rehearsal schedule treats constraints as learnable material requiring active recall, similar to educational spaced repetition systems. This pattern is being adopted from cognitive science into agent architectures by teams at Google DeepMind and Anthropic for safety-critical coding agents.
