Contradicting returns of `/irrelevant/file` and `/explain`

Given the example background knowledge, /irrelevant/file reports /A/B/Filename2.exe to be irrelevant and /A/B/Filename.exeto be not irrelevant. However, retrieving an explanation for /A/B/Filename.exe succeeds while requesting an explanation for /A/B/Filename2.exe results in a Bad Request response as /A/B/Filename2.exe is not irrelevant.
