Chapter 20:
Professor Quirrell raised his wand and said something that Harry's ears and mind couldn't grasp at all, words that bypassed awareness and vanished into oblivion.
Chapter 43:
Harry wouldn't let his mind see something false, and so he didn't see anything, like the part of his visual cortex getting that signal was just ceasing to exist. There was a blind spot under the cloak. Harry couldn't know what was under there.
There are blind spots in Harry's mind, and in 20 he doesn't even seem to notice it.
Doesn't the Interdict of Merlin imply that either blind spots are easily magically manufactured or that everyone has them?
