The published song is the part the world sees. Everything that made it is the iceberg underneath. The voice memo from a hotel room. The loop you stole from a beat tape you made in 2019. The cover photo your friend shot on a disposable.
For a long time we've tried to glue that iceberg together out of Dropbox folders, DAW sessions, iMessage threads, and the one Notion page you swore you'd keep updated. It doesn't work. Things move, things get renamed, things end up on a hard drive in a closet. The lineage between them, this sample came from that loop, which came from that jam, exists only in your head.
Casset's bet is that this layer deserves to be a real thing, with a real contract.
The release stays canonical
This isn't a pivot away from releases. Releases are still the canonical published artifact. They have rights. They have a manifest. They have provenance you can sign. That layer is doing its job.
What we're adding sits underneath it. A typed reference to any creative asset, whether that's a track, a sample, an instrument, or a release, that tools and agents can consume without caring what kind of thing it is. One contract. Many asset types. The release layer projects out of the asset layer at publish time, so the two histories don't drift.
Why "operating system"
Because the value isn't any one tool. The value is that every tool gets to assume the same primitives.
A creative runtime that wants to remix your catalog shouldn't have to invent its own notion of "a thing that exists." It asks for an asset, it gets one, and the lineage, the rights decision, and the provenance come along for the ride.
The OS is the boring part. The runtimes on top are where things get interesting.
What changes for you
In the near term: almost nothing visible. The point of plumbing is that you stop noticing it.
In the medium term: the answer to "where did this come from?" stops being archaeology.
In the long term: a creative tool can ask your archive a question and get a real answer, because the archive is finally one shape, not twelve.
