Big WTF moment for me. I've helped several people learn how to use this device (not my recommendation; it's what they wanted), and I've burned thrpugh quote a few of these slots, learning and showing all the features. If I actually intended use a ColdCard, I'd be slightly pissed. Why does clearing the secure element have anything to do with the finite consumable resources on the MCU?

I do not think loading temporary seeds uses slots.

You are correct. It doesnt use the SE or slots. Interestingly, they still give you the option of exporting the passphrase for temp seeds to microSD. But it doesnt work. Wonder if that's a bug.

I have so many hardware signers it's embarrassing. And I do own a Q, which is a magnificent device. The slots thing would get deeply under my skin if it would get used up by temporary seeds. Thus, ephemeral seeds, as well, which don't have to be saved to the seed vault. I don't think the possibility of me using up all 256 slots is very high the way that I use the Q. But it certainly begs the question of why. I haven't found a reasonable explanation yet. And if the why is literally planef obsolescence, that would be extraordinarily uncool.
