Pull request overview
This PR splits the “switch production environment” workflow so ENSNode routing can be switched independently of ENSDb Playground routing, and expands ENSNode’s switcher to support a third (yellow) environment.
Changes:
- Add
yellowas a selectable target environment for ENSNode switching, and remove ENSDb Playground routing from the ENSNode switch workflow. - Introduce a new, dedicated workflow to switch ENSDb Playground routing between blue/green.

Greptile SummaryThis PR splits the previously unified environment-switch workflow into two independent workflows — one for ENSNode and one for ENSDb Playground — and replaces the Railway GraphQL API version lookup with a direct call to the ENSNode
Confidence Score: 4/5Safe to merge with awareness that triggering a yellow switch will leave the Promote steps in a broken state until a guard is added. The two Promote steps in the ENSNode workflow run unconditionally for all three targets. When yellow is selected, the promote script calls

promote_vercel_deployment.sh reconstructs the ENSIndexer image tag from the reported semver version (ensindexer:<version>), which does not exist for release-candidate/preview deployments, so skopeo inspect fails — and because the promote steps run after the irreversible Traefik routing switch, the workflow aborts with production already moved to the new backend but the frontend left un-promoted.

Serialize ENSDb Playground environment switches.
This workflow mutates a single Traefik production routing key; overlapping manual dispatches can race and leave routing determined by the last Redis write, not operator intent. Add a workflow-level deployment lock.

actions/checkout persist-credentials default documentation hash pinning recommendation
💡 Result:
The actions/checkout action, maintained by GitHub, includes a persist-credentials input that controls whether authentication credentials (the GitHub token or a provided SSH key) are configured in the local Git configuration [1][2]. Default Behavior and Recommendation: The default value for persist-credentials is true [3][4]. When enabled, the action configures the runner's local Git environment with credentials, which allows subsequent steps in the same job to execute authenticated Git commands [1][5]. Security experts and industry guidance, including the OWASP GitHub Actions Security Cheat Sheet, strongly recommend setting persist-credentials: false unless your workflow explicitly requires authenticated Git operations [6][7]. This practice is recommended to minimize the attack surface by preventing credentials from being stored in the environment, thereby reducing the risk of accidental exposure if the workflow is compromised [6][7]. Action Versioning and Hash Pinning: Regarding hash pinning, it is a recommended security best practice to pin all GitHub Actions to a specific commit SHA rather than using tags (like v4) [6][7]. This ensures that your workflow consistently runs the exact same code, protecting against potential supply chain attacks where a tag might be updated to point to malicious code [7]. Example Configuration: To implement these security recommendations, use the following pattern in your workflow YAML: - uses: actions/checkout@<FULL_COMMIT_SHA> with: persist-credentials: false Replace <FULL_COMMIT_SHA> with the specific 40-character commit hash of the version you intend to use [6][7].

Harden the checkout step.
actions/checkout@v6 is tag-pinned instead of SHA-pinned, and persist-credentials defaults to true, which leaves GITHUB_TOKEN in the local git config. Pin to a full commit SHA and set persist-credentials: false unless later steps need authenticated git access.

GitHub Actions action.yml top-level description required local action metadata actionlint local action missing description
💡 Result:
In GitHub Actions, the description field in the action.yml metadata file is required [1][2]. The official GitHub Actions metadata syntax documentation explicitly lists description as a required top-level key for defining an action [1][3]. Regarding actionlint, this static analysis tool enforces metadata requirements for local actions. Since version 1.7.0, actionlint has included checks for the action metadata file (action.yml or action.yaml) [4]. If the top-level description field is missing from your action.yml file, actionlint will report an error (e.g., 'description' section is missing) [4]. Because actionlint primarily focuses on checking workflow files rather than independently validating action.yml files in isolation, you may need to ensure your action is being referenced in a workflow or test file that actionlint scans, or verify your linting configuration, to see the error reported [4].
