Two claims. Both load-bearing.
A compiler that cannot recompile itself is a rumor. Rail is not a rumor. The binary you hold rebuilds itself byte-for-byte from its own source, every release, on every backend. That's the first claim.
The second is harder to defend. It says that everything else in this stack — the TLS handshake, the plasma sim, the site you're reading — is answerable to physics. Not to npm, not to dependencies you can't audit, not to a runtime that might change under you. When a primitive runs, it runs on transistors you can point at. The distance between the source and the silicon is short and legible.
Most software companies grow by accretion. A library calls a library that calls a runtime that calls a kernel. Each layer promises to hide the one below. Ledatic is built the other way. We remove layers until what's left is small enough to carry in your head.
What's left, in our case, is: a 901 kilobyte binary that speaks TLS 1.3, verifies X.509 chains, runs a 2D magnetohydrodynamics simulation, trains a small transformer, and generates this webpage. Written in a language that compiles itself. Zero C dependencies. Zero invisible runtime.
We don't think this is the only way to build software. We think it's the way worth building the next decade's software in. The world is filling up with code nobody owns. We'd rather own ours.
If you want to watch us do it, the source is public. If you want to verify we're doing it, the entropy beacon ticks every two seconds and signs what we've been up to. The two doors below are how to start.
