Tubeless tire repair?
Yesterday one of my relatively new Schwalbe Pro One tubeless was punctured by dog knows what - I was on a gravel path at the time - I now know these tires are not suitable for light off road. The hole is on the tread and not the sidewall. Tried bacon plugs (2 separate attempts) and both failed, and one backed out. Perhaps the remaining sealant was inhibiting proper adhesion? The hole is probably .25mm in size. Was thinking of using a standard tube patch on the inside of the tire and then cover the patch with some Gorilla Tape.
Who has had success with an internal patch and what did you use?

For bigger holes or cuts you use mutiple plugs.

Dynaplug® Online Store |Dynaplug® DynaPlugger? - Tubeless Bicycle Tire Repair Kit
I just got the plastic Dynaplug. Haven't used it yet. It gets good reviews and Dynaplug has been making these type things for cars and motorcycles long before bicycle tubeless was invented.

1. Is the Dynaplug® repair permanent?
The plug material makes a permanent repair when one tire repair plug is used and the puncture is made by an object no larger than a 16d (16 penny) common nail.

I carry Stan's darts and might use them for the first time today. But that's at MTB pressure

not very successful at patching a tubeless tire once it's been goop'd with sealant... & I expect such when attempt in doing so.. basically, testing of luck.
If a plug is not able to seal the deal, then I hit the easy button & start back off with a fresh TLR tire.
Plug it your dump it.

Another vote here for Dynaplugs. I use the Dynaplug Racer tool, which is very easy to carry in a pocket and extremely quick to use. The conical brass tips prevent the plugs from backing out. I've only had to use it a couple of times over the past few years and it worked perfectly each time.
Another tip is to carry a tube of superglue, which can be helpful with sealing around plugs. Although I've never had to use it on road tyres to date.

I've had decent success gluing some waterproof canvas to the inside of the tire, but that was on a tubed tire. I've also glued fabric-reinforced rubber sheet, but that's pretty stiff material (I have that in the GP5000 tire I'm using now, and it's holding fine).
Maybe the tube patch idea to make it for sure air tight, then the canvas on top would do. The canvas prevents the hole in the tire from opening up.
I use Super Glue, but others have reported using contact cement to glue down the canvas.

A .25mm puncture is basically a pinprick, and should've sealed up before you noticed it. What sealant are you running, and what psi? Have you checked your sealant level lately?
Anyway, I would plug it carefully and ride on. If for whatever weird reason it didn't seal up by itself, a plug should work. Otherwise pull the tire and use a tire boot like the ones from Park Tools.
+1 on the Dynaplug recommendation. Bacon strips are pretty primitive in comparison.

Yeah it’s funny on the things I cheap-out on. I have successfully used bacon strips on my Conti 5000s and rode 3000 miles after with never a hitch, so I figure they were good. Should just go the Dyna-plug route and make life easy.
There still was a fair amount of sealant left in the tire case when removed but when I flatted, the pressure (70 lbs) went down remarkably fast to I guess about 30 psi. Quite the mess on the frame, etc.

I carry bacon strips on my mtn bikes but I splurged and bought a dynaplug for the road bike. I haven't used one yet but I really didn't want to worry about the higher pressure tires blowing bacon strips out.

0.25 mm is something I would need a low-magnification microscope lens to see. Are you sure you don't mean 2.5 cm, which is about an inch?

If its really only 0.25 mm you can use "super glue". Works with tubes too. Else there are proper patches for gluing to the inside of the tyre. Rema has some. They are blue, forget the name.

FWIW, & it may not apply to the OP exactly but I've had good luck with a smear of Shoo-Goo on problematic sidewalls. It's made to adhere to latex rubber shoe soles. Since tubeless sealant and many tires have a strong latex content the 2 products seem compatible for bicycle use.
I don't see how it's a big deal to let the sealant dry, rub off all that will come off & then apply Shoo-Goo in whatever rubber area needs a little extra help. If it's co-opted to help a bacon strip so so much the better.
(I've also glued down a patch of rip-stop nylon for emergency sidewall repair to good effect. Tubed, of course.)

Tubeless....amirite?
I have had luck with Effetto Mariposo's tappabuco strips. In the tread. Granted at gravel pressures.
Darts from Stans - I have had 50/50 luck with them.
Dynaplug - 50/50 luck.
Using an innertube - 100% luck.

After reaming the hole with the spiny hole reamer tool (the imagination reals) to roughen up the casing - the hole was considerably larger to insert the bacon. Mystery solved.
Gave up on the idea of patching the tire since the *&%*% thing is so tight to get on and off, it wasn’t worth the effort for a failed experiment. My thumbs and finger tips are still sore from the efforts. So, instead of replacing with the Pro Ones, I used Conti’s latest GP 5000 variant and it popped right on and seated immediately. No struggle, no muss or fuss.
I have ridden my original Conti GP5000s on miles of gravel with never an issue, so no more uber expensive Schwalbes.

The nice thing, however, is tubeless is vastly more convenient and makes tires immune to flats.

In the instance I had a large nail get jammed into my tire. I had to use pliers to pull the nail out. I put 2 plugs in, but I still had a minor leak that would not seal. The tire only had 200 miles, so I decided to pull the tire, clear it really good, let it dry, then I put some Gorilla Glue super glue on the plugs. Since I did that, I've put over 1800 miles on the fix since and not had an issue with the tire since, and it is a rear tire to boot.

I saw the OP already ordered Dynplugs and that is my preferred plug. But I have had small leaks that won't stay sealed from ride to ride. In those cases, I have patched the tire from the inside. I use a regular inner tube patch and apply the same way. I do everything I can to clean the area and rough it up a bit. This has worked very well for me. I've put hundreds and in some cases probably well over a thousand miles on a tire with this type of patch and it holds fine until the tire is worn out.
If I have had to plug the tire, I just leave well enough alone. I've never removed a plug and attempted to patch.
As for sealant, I use Orange Seal. I do think Stan's work really well to plug punctures. But many tires seem to come with leaky side walls and I've had tires that Stans would simply never stop the sidewalls from leaking. Orange Seal seems to do that fine.
