Pre-Release

Pre-Release #69

Workflow file for this run

name: Pre-Release
# 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.
