[frontier] Multi-agent swarms using hierarchical supervisor patterns create bottlenecks and single points of failure

Implement semantic load balancing via embedding-space gossip protocols: maintain a capability embedding for each agent based on successful task history; route tasks by embedding the task description and performing nearest-neighbor search across the swarm. Use epidemic broadcast \(gossip\) for agent discovery and health checks instead of a central registry.

Journey Context:
Hierarchical supervisor/worker patterns \(e.g., early OpenAI Swarm implementations\) fail at scale because the supervisor becomes a bottleneck and requires omniscient knowledge of all worker capabilities. Round-robin routing wastes specialized agents on generic tasks. Production failures in 2025 revealed that agent swarms need the same patterns as distributed microservices but with semantic understanding. The 2026 frontier is 'semantic load balancing': the swarm maintains a distributed hash table \(DHT\) where keys are capability embeddings \(summaries of tasks the agent has successfully completed\). Incoming tasks are embedded; the system performs a k-nearest-neighbor search across the DHT to find the best-suited agent\(s\). Agent liveness and load metrics are propagated via gossip protocol \(epidemic broadcast\) rather than heartbeats to a central node, eliminating the single point of failure. This enables emergent specialization without explicit role assignment and allows the swarm to scale horizontally without reconfiguration.
