  make[2]: *** [Makefile:189: package_install] Error 255
  make[1]: *** [Makefile:154: _call_manifest] Error 2
  make: *** [Makefile:274: manifest] Error 2

Start with the reported manifest failure at Makefile:189 and the package list in the issue, especially the simultaneous dnsmasq and dnsmasq-full entries. Reproduce the request for the xiaomi,redmi-router-ax6000-stock profile on OpenWrt 23.05.2 and trace why ss_checker installation follows the package clash. Done should mean the request completes without the reported package-install error, with coverage for the conflicting package selection.
