Zones, address sets (IPv4 and IPv6 mixed, dynamic sets with timeouts) and services, ordered rules in the early, input, forward and output chains, port forwards with hairpin NAT and IPv6 pinholes, source NAT, redirects, and switchable built-ins (loopback, conntrack, ICMPv6, antispoofing, MSS clamping, DHCPv6 client, flowtable). Every change is validated, checked with nft -c and applied in one transaction to Housecarl's own table, inet housecarl; changes made over the network roll back unless confirmed, and the confirmed ruleset is loaded at boot by housecarl-ruleset.service. An empty configuration applies nothing. Also: hit counters and the drop log (nflog), 'hc import' of an existing nftables ruleset and 'hc takeover', the hc CLI, the REST API and the web UI, users, scoped tokens (sets:write:NAME), the audit log, the web UI's certificate through Jarl, Debian packages, docs, unit tests with real nft 1.1.3, and an e2e test with real traffic (71 checks).
