A quart of working solution will tone ~ 35 prints. That's a lot of prints to tone in one session. How long will the working toner keep in a topped-off brown bottle or container before it becomes useless

Toner doesn't age like developer. My experience is that it lasts until the metal content in the toner solution has been depleted.
I don't tone that often. As a result, I have an 8 ounce bottle that I've used for years. Haven't had a problem.
I hope not. Last year or so, I bought a gallon of the stuff for a lifetime supply. It was something like $45 from Calumet. I think that they were clearing out their stock.
