# publish-transaction-shaped

Fixture for the Buildchain publish transaction contract.

It represents a release unit with three required artifact families:

- npm package metadata;
- OCI image digest;
- binary archive digest.

The fixture does not publish to external services. `lifecycle.publish` writes
generic Buildchain evidence to `BUILDCHAIN_PUBLISH_EVIDENCE`, which is enough for
tests and for consumers to understand the expected shape.
