This repository uses a dual license, matching the sibling agentrust-io
repositories: Apache-2.0 for code, CC BY 4.0 for the registry data, schemas,
and documentation.

Markdown files at the repository root)

WHY THE SPLIT
=============
The repository was previously declared CC BY 4.0 in full, including the
Python under src/, tools/, and aggregator/. Creative Commons explicitly
recommends against CC licenses for software: they grant no patent rights,
carry no software-tailored warranty disclaimer, and are not OSI-approved,
which some corporate policies reject outright. Anyone who needs to mirror
this registry has to run that code, so the code needs a license written for
software.

Registry entries, proofs, and schemas stay under CC BY 4.0. They are data
and specification material, which is what CC BY is for.
