Resolve "audio or video avoids automatically playing audio"

[ ] I think duration needs to be removed from the applicability. Of the input rules, one essentially handles <3 seconds and the other handles > 3 seconds, saying all videos are > 3 seconds essentially only makes the second rule apply.
[ ] Custom controls video 'play/pause' button shows play even when the video is autoplaying instead of the expected 'pause' to stop the video.

[ ] The data isn't 100% consistent. Given this is because of technical issues, and I do not believe there is anything in the missing test data that would cause issues, I am personally satisfied with the amount of data there is.
[ ] It seems to me this rule can be done in one of two ways. Either as a composite rule like is now, but then the "3 second" thing in the applicability is unnecessary, or we could have just a single atomic rule that maps directly to 1.4.2, by putting the 3 second audio exception into the applicability. I personally would prefer that solution. It seems cleaner to me, but I'd be okay with either solution.

[ ] With mechanism assumptions, is it necessary to use "instrument"? -- Suggest splitting Passed Ex 1 into two separate examples: one for pause/stop and one for volume control Splitting hairs but Passed Ex 2, which does not play for longer than 3 secs, would be not applicable for 1.4.2, not pass.
[ ] WCAG Non-interference is listed as "Not required to conformance to any W3C accessibility recommendation." but https://www.w3.org/WAI/WCAG21/Understanding/conformance, under Understanding Conformance Requirements, "There are five requirements that must be met in order for content to be classified as 'conforming' to WCAG 2.0." Non-interference is Requirement 5.
[ ] One of the Expectations is that the target passes Audio Or Video That Plays Automatically Has No Audio That Lasts More Than 3 Seconds. 1.4.2 only applies to audio that lasts for more than 3 seconds, so [...] no audio that lasts more than 3 seconds would be inapplicable, not pass.
