I discussed I7 scope in detail here.
The ‘contents of a transparent closed carried container in darkness are in scope’ quirk is a longstanding unrevised bug/feature of the language- which I recently mentioned again to @GrahamNelson alongside the other quirks mentioned here. It’s a matter of reasonable debate the extent to which invisible possessions, particularly direct possessions, should nevertheless be routinely identifiable to their owner. Sight is not the only sense. I’m not sure whether anything will be changed. Graham naturally has his own views on the rights and wrongs of these things and it’s ultimately his call.
If these edge cases really bug you, you can manually remove things from scope by using Scopability extension by Brady Garvin or add them to scope using After Deciding the Scope rules.
