This is my first set of tubeless tires so I claim total ignorance. What happened here? Tire didn’t go flat or lose any air but clearly the sealant exploded out of it from somewhere. What do I need to do now aside from clean up the spew? Add more sealant? Look for a puncture to patch?

Looks to me like you had a small punny and after a few rotations it sealed itself….that explains the sealant sprayed over your tube…..I had a similar experience recently and didn’t raise till the end of my ride…but in my instance I could still make out the small hole that had sealed itself..300km later it’s still fine and no more leaks…
You may need to add a bit more sealant, I haven’t yet
Did you KOM?
Yes, add more sealant. You clearly lost a little.
If you didn’t go flat, then your sealant did the thing. You got a knick or a hole or a small slash, which allowed pressure (and sealant) to escape the system. When the sealant was exposed to air under pressure, it coagulated, and sealed the puncture. It usually takes 1 or 2 spins for the hole to seal, but in that time it is open and spewing sealant.
Now, if you made it home and it’s still holding air, you’ve got two options.
1. Keep riding! Either the clot will hold, and nothing else happens *or* the clot eventually blows out, and the process repeats itself.
2. Take the tire off and properly patch the hole. I personally prefer the Lezyne plug-patch things. If you go this route, it’ll get messy, but it is a longer-lasting fix for sure.
Welcome to the world of tubeless. Heads up, it usually ruins clothes.
