Promotion Process Constraints

Every code change is tied to a change request

Developers sign their modification using GPG

Master branch integrity is preserved by the

pull request process

The pipeline builds and tests the code for pull requests

The pipeline publishes the smart contract to the artifact repository when changes are tagged

Each organization receives a notification when

a new version is available
