I have never thought that the codes you reference are super secret or even important - I ignore them.
“The codes and “Route T” stuff make it look like some serious spy communications, but I noticed something about the codes...”
I’ve never thought such codes were “serious spy communications” but instead read over them as “garbage characters” or something meant for others. I do recall Q said “some disinformation is necessary” (not all readers of Q drops are well-intentioned) and I could see the Q group padding posts with such codes.
And I always figured the codes were there for the autists or for outside communications. Way past my expertise.
I think the anons have figured out some of them as referring to papers, briefs, etc. but I couldn’t give you an example. Just seems I’ve read that.
I’m sure some are disinformation also.
In the earlier phases of Qanon. he said that every space, every keystroke mattered. Now, he apologizes for his typos!
