Possibly, but I'm not finding slime or mold or anything anywhere else in the basin. It wasn't even slick when I did the original inspection.

Or maybe your inspection removed some slime mold which was allowing water to leak past?

Okay. So it seems the tank was a little off kilter--one or two degrees off vertical. Making it vertical has seemed to solve the problem.

This one is maybe ten years old, which seems young to me. But I'm aware they don't make things like they used to. I got in there and simply wiped the inner valve surfaces down, feeling for any deformities. I found none. No cracks, bends, pits, warts, or blistering. I let it fill back up and get seated, and the self-flush seems to have stopped. I'll keep an eye on it.

They get hard with age and stop sealing so well. replace it if that's no cure than drain the tank and inspect the valve seat. Hard acidic water can cause pitting in brass fittings. Feel the seat with your fingers and if it's all roughed up and pitted that 'll be the culprit. I've popped 'em off and trimmed 'em back into fine shape on a lathe, others I've treated with a heavy coat of epoxy then used a flat piece of wood and some abrasive paper double sticky taped on to get a flat sealing seat Use progressively fine abrasives starting with maybe 180 or 220 then a fine abrasive like 600 or 800 at the end.

My toilet has started to do a partial flush by itself. Lasts a couple of seconds and stops. There is no external leak, and the water level never goes above the overflow tube. The ball-cock / flush-valve appears to work properly and doesn't hang on anything. I guess the culprit must be the flapper valve?
