The expression "typos are canon" has a long and wordy history, but most of it is discovering that you made a typo and that the thing you wrote became so much better in this unintended form

@Sargoth like http referer headers
@ashfurrow "why are they like this?"
"no reason. it's implemented now, tho, so it's canon"
