Report #38185

[frontier] Multi-agent sessions converge on homogeneous 'median' personalities, losing specialized roles \(echo chamber\)

Implement 'personality hardening': serialize agent identity into immutable 'constitution' blocks that are re-injected before every inter-agent message, overriding consensus pressure

Journey Context:
In multi-agent systems \(AutoGen, CrewAI\), agents naturally drift toward consensus to minimize conflict \(the 'Echo Chamber' effect\). Standard practice sets identity at the start, but the 'sender-receiver' dynamics cause receivers to adapt to senders over time. Personality hardening treats identity as a cryptographic constant, re-injected into the context window of every single message exchange, not just the system prompt. This maintains role boundaries against the gravitational pull of consensus. It differs from standard multi-agent configs by being stateful at the message-passing layer rather than the session layer, preventing 'role bleed' between turns.
