Hm, certainly don't want indirectly hackable lore entries due to manually assigned queries on a local terminal like the case you mentioned (actually the only case in the game I think xD)*, but I'm seeing that the "local access only" response on derelict terminals was an intentional decision, likely to avoid confusing players who might think they typed it incorrectly, added long before the "local access" terminals were a thing, and even before hacking autocompletion, so maybe it's not necessary anymore.
*Edit: Oh, funny enough I already took this into consideration in the code, but not for that one particular terminal xD
Edit 2: Oh, hm... well there's notes that this particular instance is supposed to be allowed as an indirect way to get more info from the database, since technically terminals like this are still connected to the network, just indirect hacks aren't possible... Guess I should change it if it might confuse people, even though such a change will conflict with lore elsewhere implying that these terminals are still actually in some ways interacting with the network on a limited basis, which is why it was this way in the first place...
