Summary

Replaces the single-workflow release model with the two-phase release process defined by RFC 0020. Every release is now split into two manually-triggered workflows with a PR-based human review gate between them, satisfying segregation-of-duties requirements and preventing phantom releases.

  • Pre-release workflow — validates the version, creates the release branch (if needed), updates version references, opens a release PR against the release branch, and opens a dev-bump PR against the source branch
  • Version gate — a CI check on release-branch PRs that validates release.yaml contains a concrete version (not the 0.0.0 sentinel) and that all declared dependencies have published GitHub Releases
  • Release workflow — reads the version from release.yaml, runs smoke tests, creates the git tag, builds the WASM binary and container image, and creates the GitHub Release as the final step
  • release.yaml — introduced as the machine-readable source of truth for version and dependency information, using 0.0.0 as the sentinel value on main

The old automated-release and sector-release workflows are removed. The build-image workflow is refactored to support workflow_call so the release workflow can invoke it directly with explicit image tags and git ref, and the KUADRANT_DEV_PAT secret dependency is eliminated in favor of GITHUB_TOKEN. The container registry org is now configurable via the IMG_REGISTRY_ORG repository variable, enabling forks to build images to their own registry namespace.

RELEASE.md is rewritten to document the new process including quick start, standard minor release, patch release, and repository configuration requirements.

Testing Artifacts

A full end-to-end testing was performed on a fork to validate the workflow:

Step Link
Pre-release workflow run Run #4
Release PR PR #6 — chore: prepare release v0.14.0
Version gate check Validate Release Version
Dev-bump PR PR #7 — chore: bump version to 0.15.0-dev
Release workflow run Run #2
Release branch release-0.14
GitHub Release v0.14.0

📝 Walkthrough

Walkthrough

The release process now separates pre-release preparation from release execution. It validates version metadata, creates release pull requests, runs release checks, builds artefacts, and publishes tagged WASM and container releases. Automated and sector release workflows are removed.

Changes

Release metadata and validation

Layer / File(s) Summary
Release metadata and validation
.github/scripts/*, .github/actions/install-yq/action.yaml, .github/workflows/version-gate.yaml, release.yaml, RELEASE.md
Cargo metadata is authoritative. Scripts synchronise and validate release.yaml. Workflow gates run the checks. Documentation describes the two-phase process.

Pre-release orchestration

Layer / File(s) Summary
Pre-release orchestration
.github/workflows/pre-release.yaml, .github/actions/prepare-release/action.yaml, .github/actions/setup-rust-wasm/action.yaml
The workflow validates the requested version, creates release branches, prepares version files, opens pull requests, and creates a follow-up development-version update from main.

Release execution

Layer / File(s) Summary
Release execution
.github/workflows/release.yaml
The workflow validates the release branch, runs smoke tests, creates a tag, builds WASM and container artefacts, and publishes the GitHub release.

Reusable image build

Layer / File(s) Summary
Reusable image build
.github/workflows/build-image.yaml
The image workflow supports reusable calls, supplied references and tags, registry secrets, and resolved commit SHA build arguments.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to ec8ee

This PR changes the release process, but the current configuration includes a workflow setup step that can prevent dependent workflows from loading, release inputs that may execute commands before validation, and broader write permissions than necessary. These issues can block releases or allow unintended repository changes, so the PR is not merge-ready until they are addressed.

Tag creation is not idempotent — failed runs after tagging require manual recovery

The read-version job checks for an existing GitHub Release (line 52) but not for an existing git tag. If the workflow fails after the tag job pushes the tag but before create-release completes, re-running will pass the release-existence check but fail at git tag with "tag already exists". The user must manually delete the tag to recover.

Pass inputs.image-tags via environment variables to prevent shell injection

${{ inputs.image-tags }} is interpolated directly into shell commands. When called from release.yaml, the value derives from release.yaml's version field, which is not semver-validated at release time. A crafted version could inject arbitrary shell commands.

Missing semver format validation across version gate and release workflow

Both the version gate and the release workflow's read-version job check only for 0.0.0 and empty, but neither validates semver format. The pre-release workflow validates semver with a regex (line 33), but if someone manually edits release.yaml on a release branch, the version gate will not catch a non-semver version, and the release workflow will use it without validation — producing invalid tags and enabling template injection in downstream shell commands.

  • .github/workflows/version-gate.yaml#L22-L33: Add a semver regex check (e.g., ^[0-9]+\.[0-9]+\.[0-9]+(-[0-9A-Za-z.-]+)?(\+[0-9A-Za-z.-]+)?$) to the "Validate version is not sentinel" step, matching the pattern already used in pre-release.yaml line 33.
  • .github/workflows/release.yaml#L29-L45: Add the same semver regex check to the "Parse version from release.yaml" step, after the 0.0.0 check and before computing TAG.

Avoid interpolating inputs.version directly into the shell command. GitHub expands ${{ inputs.version }} before Bash runs, so a crafted value can break out of the quoted URL. Pass it via env, validate the version format, and use the shell variable instead.

This PR uses the same release.yaml as version source of truth pattern as limitador#500, where I raised a concern about version drift between release.yaml and Cargo.toml (review). That thread is still open.

Since wasm-shim implements the identical scheme (release.yaml version + 0.0.0 sentinel, Cargo.toml updated separately in prepare-release/action.yaml), whatever we land on there should apply here too. I'd suggest holding this implementation detail open until the limitador discussion converges, so we don't merge one pattern here and then have to rework it once #500 settles.

# Release Scripts

Helper scripts for the two-phase release process. All scripts use `release.yaml` as the default path but accept an override as the first positional argument.

Correct the override argument description.

validate-release-yaml.sh takes the branch name first and release.yaml third. Its documented signature at line 54 already shows this. Limit the first-positional-argument statement to the other scripts.

arguments to exclude validate-release-yaml.sh from the claim that release.yaml
overrides are accepted as the first positional argument. Preserve its documented

first-argument override description for the other scripts.

Prevent command execution from workflow inputs.

Line 36 interpolates inputs.version before validation. Lines 61 and 195 interpolate the unvalidated inputs.source-branch. A crafted dispatch input can alter shell parsing and run commands with the workflow token.

Pass dispatcher-controlled values through env, then expand only shell variables such as "$VERSION" and "$SOURCE_BRANCH". Validate SOURCE_BRANCH as a branch name before use.

Use one strict SemVer validator.

The same pattern in pre-release.yaml and prepare-release/action.yaml accepts 01.2.3, 1.2.3-01, and 1.2.3-alpha..1. Replace both checks with one strict SemVer validator.

Not sure I follow what you are saying here. The bumping of the dev version PR is created after the release PR is created. Are you wondering if the dev bump PR should be created after release PR is merged?

To clarify what I meant: the workflow should first create the release PR, then create PR for bumping the dev version. bump-dev should depend on open-release-pr succeeding, not just prepare-release. If open-release-pr fails, bump-dev could still succeed and open its PR. Limitador does this already.
