Verified releases

YEA is software that holds authority over your money and calendar, so you should be able to check that what you install is what this repository built. Every release is built and published by GitHub Actions (release.yml, docker.yml) from a tagged commit:

Artifact	How it's published	Provenance
npm @yea-protocol/sdk, @yea-protocol/mcp, @yea-protocol/cli and @yea-protocol/stripe	npm trusted publishing (OIDC), except the first release; see below	npm provenance (--provenance) plus a GitHub build attestation of each .tgz
PyPI yea-sdk and yea-mcp	PyPI trusted publishing, from the first release	GitHub build attestations of each wheel and sdist
ghcr.io/yea-protocol/yea	Docker build on release tags	GitHub build attestation of the image
GitHub release	The npm and PyPI artifacts, plus SHA256SUMS

The first npm release uses a token. npm only lets a trusted publisher be added to a package that already exists, so v0.1.0 of the four npm packages is published with a scoped automation token stored as a repository secret. Once they exist, trusted publishing takes over and the token is revoked (#31). Provenance and build attestations apply to every release either way, so the checks below work for v0.1.0 too.

Checksums, from the release page:

sha256sum -c SHA256SUMS

A verified attestation tells you the artifact was built by this repository's workflow, from the commit it names. It doesn't tell you the code is correct: for that, there's the conformance suite, the tests and the security model.
