PR Summary

Low Risk
Observability-only metric renames and a new gauge; no consensus or fee logic changes beyond recording the configured USD target.

Overview
SNIP-35 observability now names Fri gauges explicitly (snip35_fee_*_fri) and adds snip35_fee_target_atto_usd, set when the proposer computes fee_proposal from snip35_target_atto_usd_per_l2_gas.

Grafana’s Dynamic Gas Price (SNIP-35) row picks up the renamed PromQL and a new Fee Target (USD per 1B L2 gas) panel (atto_usd / 1e9). Consensus orchestrator and dashboard code stay aligned on the same metric constants.
