Struct OfflineRetentionPolicy 

pub struct OfflineRetentionPolicy {
    pub online_ttl: Duration,
    pub offline_ttl: Duration,
    pub keep_last_n: usize,
}

Offline retention policy for connectivity-aware lifecycle

When a node is offline, it cannot contribute to the mesh anyway. More aggressive eviction saves storage and battery while preserving the ability to re-sync latest state from peers when reconnected.

Fields

online_ttl: Duration

TTL when node is online (normal retention)

offline_ttl: Duration

TTL when node is offline (aggressive eviction)

Typically 10x shorter than online_ttl to free resources

keep_last_n: usize

Always keep last N items per collection, even when offline
