Artifacts

The checkable subset of Contubernium, served from the project's own domain: enough to run a witness, check a receipt offline, and implement the specification independently against the conformance vectors. Integrity: curl -sO https://contubernium.io/artifacts/SHA256SUMS && sha256sum -c SHA256SUMS

Everything here is source-available for verification, not open source: audit freely, verify freely, run a witness — those grants are permanent. Use beyond that is reserved; see the Verification License. The specification may be implemented independently, and the vectors test any implementation.
