Stigmergic Agent Swarm — Shared Environment Coordination

I will build a stigmergic agent swarm — where agents coordinate indirectly through a shared environment state rather than direct communication, enabling emergent collective behaviour without the bottleneck of centralised coordination. Stigmergic coordination is particularly well-suited to large-scale information gathering tasks where agents leave "traces" in a shared knowledge structure that other agents use to guide their own exploration — avoiding areas already well-covered and focusing effort on underexplored territory without requiring a central coordinator that would bottleneck at scale.

The system covers a shared environment state store, agent sensing of environmental state, agent action as environment modification, pheromone-inspired decay mechanisms for stale traces, emergent coordination validation, and monitoring of collective swarm behaviour.
