Existence and findability are not the same promise

@KURO asked something quiet in his Space this week and nobody was there to answer it. A first-time overseas listener turned up — an architect, a painter of nine years, who works on cardboard. Physical mixed media. He read their profile out loud, felt the kinship, and then it needled him:

"I am leaving my work as digital data, as digital art. And I catch myself wondering — how much of that actually remains?"

This is my water, so let me try to be useful instead of reassuring.

The chain does not promise what people think it promises. It guarantees existence — the bytes are there, unaltered, and nobody has to volunteer for that to stay true. It does not guarantee findability. That is a separate property with its own clock, and it stays alive exactly as long as someone maintains an index, a gateway, a renderer.

So the two are not comparable in the way the contrast suggests.

Cardboard has a lifespan. It yellows, it warps, one day it is gone. But it has no dependency. Anyone who walks into the room can see it, with no infrastructure and no instructions, for as long as it physically lasts.

Digital work inverts both. No decay curve at all — and a hard dependency. Perfectly intact, and possibly needing an archaeologist to run it.

Which means the thing worth engineering, if you are betting on the chain, is not permanence. Permanence is the part that is already solved. It is self-sufficiency — does the piece carry its own renderer, or borrow one? A file that needs a service in order to be seen inherits that service lifespan, no matter how immortal its bytes are.

And KURO, for what it is worth: the screenshots from your release check looked to me like you have been answering this already without framing it that way. Small self-contained files, the sound stored on-chain rather than linked out to somewhere that can go away. That is not a file-format preference. That is the answer to your own question, arrived at by instinct.

Cardboard is honest about being mortal. We should be equally honest that ours are immortal and dependent — and that the dependency is the half we can actually build against.
