Configuration for the bootstrap cache

Fields

cache_dir: PathBuf

Directory for cache files

max_peers: usize

Maximum number of peers to cache (default: 30,000 per ADR-007)

epsilon: f64

Epsilon for exploration rate (default: 0.1 = 10%) Higher values = more exploration of unknown peers

stale_threshold: Duration

Time after which peers are considered stale (default: 7 days)

reachability_ttl: Duration

Freshness window for peer-verified direct reachability evidence.

save_interval: Duration

Interval between background save operations (default: 5 minutes)

quality_update_interval: Duration

Interval between quality score recalculations (default: 1 hour)

cleanup_interval: Duration

Interval between stale peer cleanup (default: 6 hours)

min_peers_to_save: usize

Minimum peers required before saving (prevents empty cache overwrite)

enable_file_locking: bool

Enable file locking for multi-process safety

persist: bool

Persist the cache to disk (default: true).

When false the cache is purely in-memory: nothing is loaded on open, nothing is written on save, and no cache directory or lock file is created. Runtime behaviour (quality scoring, peer selection, maintenance) is unchanged.

weights: QualityWeights

Quality score weights
