PrefixSet: git-backed CIDR files via gitshallow, refreshed every 47 min. DomainSet: takes pre-parsed (staticPrefixes, domains []string); resolves hostnames every 5 min, retaining stale IPs on failure. Both use atomic-swapped ipcohort.Cohort for lock-free reads. ParseDomainSet(RecordReader) parses rows into prefixes and hostnames; caller constructs the record reader (e.g. csv.Reader with delimiter, comment char). RecordReader interface is satisfied by *csv.Reader. commaify uses plain string concat (integers max ~7 groups).
