Will the comprehensive rulebook of Magic: The Gathering contain no errors at any point before 2030?

Wizards of the Coast's rules page says:

The Comprehensive Rules of Magic is a reference document that holds all of the rules and possible corner cases found in Magic.

This is false. There are all sorts of errors, omissions, and ambiguities, which are well known in the Magic rules community. Situations that the rulebook doesn't cover regularly come up at high level tournaments, and judges have to make fiat rulings, check the Twitter posts of Magic's rules manger, dig through the forums for precedent, etc.

If they update their rulebook to remove all significant ambiguities, this market resolves YES. If they haven't done so by the beginning of 2030, it resolves NO.

In order to resolve YES, the rulebook need only cover the standard two-player game rules. It doesn't need to fully cover multiplayer, Commander, or any other variants, nor the Arena-only mechanics. It doesn't need to cover tournament policy or other things that aren't really the domain of the rulebook, such as it currently touches on in sections 728 and 729. Nor does it need to precicely define every English term in pseudocode; if a fluent English-speaker with a technically-oriented mindset can know what it means with high confidence, that's good enough.

If Wizards comes out and says "yes we know the rulebook doesn't cover anything, that's intentional", that isn't sufficient to resolve this market to YES, even though it wouldn't technically be an "error" after that point.
