What
Sandbox diagnostics now flag permission rules that name an IPv6 address without square brackets, both for domain rules and for injected hosts, so a rule that silently fails to match gets called out.
Details
Two new checks, one for domains and one for inject hosts; the existing Linux glob-pattern warning summary now shares a common formatter.
