[frontier] Individual agent identity blurs in multi-agent debates or workflows after 20\+ rounds of interaction

Implement 'Identity Stamping': require each agent to prefix outputs with 'As \[AgentName\], I...' and maintain separate context buffers per agent that don't get concatenated into a single shared history; use a moderator to synthesize cross-agent state without blending voices.

Journey Context:
In multi-agent systems \(AutoGen, CrewAI, etc.\), the standard pattern is to concatenate all agent outputs into a single shared context window. After 20\+ rounds of debate or workflow, this creates 'Identity Fragmentation' where the attention mechanism can no longer distinguish which statements came from which agent. The model starts to hallucinate that Agent A said things that Agent B said, or worse, adopts a blended personality that ignores specific constraints of individual agents. The naive fix of 'label each message with the agent name' is insufficient because the content still gets processed through the same attention layers. The robust fix is architectural separation: maintain separate context windows or use 'Identity Stamping' where the model is forced to generate self-referential identity statements that strengthen the attention pathway between the agent name and the content, and use a moderator agent to synthesize information without concatenating raw histories.
