| # PRE-RELEASE PROCESS | |
| # | |
| # === Automated activities === | |
| # | |
| # 1. [Seal] Bump to release version and export source code with integrity hash | |
| # 2. [Quality check] Restore sealed source code, run tests, linting, security and complexity base line | |
| # 3. [Build] Restore sealed source code, create and export hashed build artifact for PyPi release (wheel, tarball) | |
| # 4. [Provenance] Generates provenance for build, signs attestation with GitHub OIDC claims to confirm it came from this release pipeline, commit, org, repo, branch, hash, etc. | |
| # 5. [Release] Restore built artifact, and publish package to PyPi prod repository | |
| # 6. [PR to bump version] Restore sealed source code, and create a PR to update trunk with latest released project metadata | |
| # NOTE | |
| # | |
| # See MAINTAINERS.md "Releasing a new version" for release mechanisms | |
| # | |
| # Every job is isolated and starts a new fresh container. | |
