It does not seem to be boiled anywhere, and sugar content is relatively low, and it is highly possible that this thing is contaminated by lactics by now with all the date and sesame. Which is probably good thing, it would bring some sourness and - as others here mentioned - might prevent further fermentation at some point, although there is no sure bet, as well as with pretty much everything here. If bubbling in pure sugar mixture started after 3 weeks, that’s very late start, my bets are that yeast is not alone there.

So, if it smells nice, it should be safe according to US government regulations (lol yes), can’t be safer - but keep your toilet paper ready and get a plunger before you need it if you don’t have one, just in case.
