- `prometheus.yml` – Scrapes both blockchain node and mock coordinator/miner metrics.
- `grafana-dashboard.json` – Panels for block interval, RPC throughput, miner activity, coordinator receipt flow, **plus new gossip queue, subscriber, and publication rate panels**.
- `grafana-dashboard.json` – Panels for block interval (including latest interval gauge), RPC throughput, miner activity, coordinator receipt flow, gossip queue/subscriber/publication metrics, and PoA proposer visibility (rotation counts, blocks proposed per proposer).
- `alerts.yml` – Alertmanager rules highlighting proposer stalls, miner errors, and coordinator receipt drop-offs.
- `gossip-recording-rules.yml` – Prometheus recording rules that derive queue/subscriber gauges and publication rates from gossip metrics.
