- Parsers: Superpower for all (Directive, FileLine, Include, DhcpHost, Leases, Hosts) - Shared ConfParserHelpers (Token, OptionalCommentPrefix) - DnsmasqConfOptionRegistry + DnsmasqOptionKind: typed options (ConfFile, ConfDir, Domain, DhcpRange, Server, Local, Address, DhcpOption, DhcpHost, Path, Flag, etc.) - EnsureManagedConfigHostedService: append conf-dir= to main config if missing, then create managed file; DnsmasqOptions + Dockerfile comments for permissions - Renames: ConfigLine->DnsmasqConfLine, ConfigSet->DnsmasqConfigSet, etc. - Test harness: entrypoint in scripts/, prepare-test-mount improvements - Status/Reload API and UI: stdout+stderr, exit code
