Reproducible by URL
Reproducibility is usually a promise. In Scellis it is a property of the architecture: any run can be reconstructed, bit-for-bit, from the link you share.
Content-addressed everything#
Every artifact — a dataset slice, a trained checkpoint, an intermediate tensor — is addressed by the hash of its bytes. A hash is a contract: the bytes behind sha256:… never change.

dataset@3 · model@7 · seed 42 · tier prodNote
Before anything is trusted, it is verified against its hash; a mismatch is treated as corruption and refetched — never silently used.
Fixed seeds, stamped provenance#
Determinism is explicit. RNG is seeded and threaded through the run, the determinism tier is never silently defaulted, and every result carries provenance describing exactly how it was produced — which inputs, which versions, which effects.
Put those together and a URL becomes a complete, executable description of a result. Send it to a colleague and they get your run — not a screenshot of it.
