[frontier] Agents fall into behavioral ruts and stop self-correcting due to attention collapse on recent tokens

Deploy entropic forcing: Every K turns, regenerate the agent's current plan using high-temperature sampling \(T=0.8-1.0\) with a different random seed. Compare the high-entropy trajectory against the low-temperature baseline using embedding cosine similarity. If divergence exceeds threshold \(indicating the low-temp path has overfitted to a local minimum\), trigger 'recalibration' of constraints from persistent store.

Journey Context:
As sessions lengthen, agents fall into 'attractor states'—reusing the same patterns and ignoring edge cases they initially checked. This is analogous to mode collapse in GANs or pure exploitation without exploration in RL. The attention mechanism overfits to recent high-reward patterns. By forcing periodic high-temperature 'hallucinations' and measuring trajectory divergence \(similar to Monte Carlo Tree Search restarts\), you detect when the agent has become over-committed to a drifted interpretation. The divergence metric acts as a canary for constraint erosion—if the agent can generate a valid but different plan, it hasn't overfitted to its current \(possibly drifted\) constraints.
