[frontier] Persona Echo Chamber: Agents amplify their own recent tone, causing personality creep toward extremes

Apply Periodic Persona Re-anchoring: every 20 turns, inject a calibration block containing the original persona description and a divergence check: 'Compare your last 5 responses to your baseline tone. Adjust to match baseline.'

Journey Context:
This is an emergent property of autoregressive generation where the model conditions on its own previous outputs. Over time, 'slightly formal' becomes 'extremely stiff.' Simple summarization doesn't fix it because the summary captures the drifted tone. The fix requires an external, immutable reference point \(the original prompt\) to be re-injected as a 'north star.' This creates a corrective feedback loop that prevents the echo chamber effect.
