2026-01-10Implement relay naughty list featureDanConwayDev
Add naughty list tracking for relays with persistent infrastructure issues (DNS failures, TLS certificate errors, protocol violations) to reduce log noise and provide better visibility via metrics. Key features: - Classify errors into naughty (persistent) vs transient (temporary) - Track naughty relays with category, reason, and occurrence count - Log WARN on first naughty occurrence, DEBUG on repeats - Automatic expiration after 12 hours (configurable) - Prometheus metrics for monitoring naughty relays by category - Periodic cleanup task integrated with health checker Components added: - src/sync/naughty_list.rs: Core naughty list tracker with error classification - NaughtyListTracker integration in RelayHealthTracker - Connection error handling updates in sync manager - Naughty list metrics (total by category, detailed info per relay) - Config option for naughty_list_expiration_hours (default: 12) Closes DNS lookup failures and TLS certificate errors tracking issues.

Main lib (src/): - Add #[allow(dead_code)] for build_info field (stored to prevent Prometheus unregistration) - Add #[allow(dead_code)] for first_seen field (reserved for future rate limiting) - Replace .or_insert_with(RelaySyncNeeds::default) with .or_default() - Replace manual div_ceil implementations with .div_ceil(100) Test code (tests/): - Replace .expect(&format!(...)) with .unwrap_or_else(|_| panic!(...)) - Remove needless borrows in fetch_metrics() calls - Add #[allow(dead_code)] and #[allow(unused_imports)] to test helpers module grasp-audit: - Apply cargo fmt to fix formatting
