Report #55331

[frontier] Multi-agent swarms experience role confusion after 50\+ turns as agents accumulate cross-context contamination

Implement Role Re-anchoring Protocol - every 25 turns, agents broadcast a 'role checksum' \(hash of core competencies\) via structured JSON handshake and re-negotiate task boundaries if semantic drift >20% detected

Journey Context:
Swarms often assume static role assignments, but long sessions cause 'capability creep' where agents start handling tasks outside their specialization due to context contamination during handoffs. Teams try to fix this with stricter handoff filters, but this breaks fluidity. The protocol creates an explicit 'barrier' moment where agents must declare their identity in a structured format \(JSON checksum, not natural language\) that is parsed programmatically. If the drift detection \(comparing current role checksum to baseline\) exceeds 20%, the swarm triggers a 're-balancing' event, redistributing tasks to restore specialization. This differs from simple 'agent.refresh\(\)' because it preserves task state while clearing role contamination, and uses a decentralized handshake rather than a central orchestrator.
