Unpack XKeen into a temp dir, verify, then move into place so an interrupted update never leaves a half-written install. Add a gzip -t pre-check for the mihomo archive with backup restore, and a minimum-size guard for core downloads to reject truncated/stub files.
Enable geo-auto-update in the generated mihomo config (mihomo manages its own GeoSite/GeoIP/ASN, XKeen's xray dat files are unused for it). Make 'xkeen -ug' aware of the active core: for mihomo it explains geo-auto-update and only reapplies GeoIPSET instead of touching unused xray dat files.
Make the mihomo Go GC soft memory limit configurable via xkeen.json (.xkeen.gomemlimit_percent / .xkeen.gomemlimit_mb) instead of a hardcoded value. Default stays at 50% of RAM (unchanged behaviour); an explicit MiB value has no default. An external GOMEMLIMIT still wins.
On short DHCP leases NDM invokes netfilter.d every renew, usually with the same WAN IP. Remember the last WAN IP and, if it hasn't changed and the chains are intact, skip the redundant route/rule work.

Что и зачем
На коротких DHCP-lease NDM вызывает
netfilter.dна каждый renew, обычно с тем же WAN IP. Запоминаем последний WAN IP и, если он не сменился и цепочки целы, пропускаем лишнюю работу по маршрутам/правилам.Как проверял
На роутере Keenetic (mihomo/TProxy) с частыми renew: цепочки остаются целыми, лишняя работа не выполняется;
sh -n.Часть 6/8 — после части 5.
Часть стека харденинга. Полный порядок влития: 1 inject_var → 2 RCI/dry-run → 3 установка → 4 mihomo-geo → 5 GOMEMLIMIT → 6 WAN-skip → 7 hook-renew → 8 serialize. Ветка включает коммиты предыдущих частей — diff очистится после их мержа.
