# @suaveplan/network-plugin-circuit-breaker - Circuit-breaker plugin for mesh relay paths: per-path state machine, registry, half-open probes, and relay middleware integration

## Summary

Mesh-level circuit breakers: per-path state machine (`CLOSED → OPEN → HALF_OPEN`), registry, half-open probe loop, and relay middleware integration. Fast-fails dead relay paths so retries don't cascade.
