# Tears down stage `pr-<n>` when `relay:preview` is removed or the PR closes,
# and retries teardown for closed labeled PRs on a schedule. A label stays on a
# PR only while its teardown is outstanding, so the scheduled retry lists
# exactly the failures.
#
# This runs under pull_request_target, so the workflow and the Alchemy program
# come from the default branch. No PR code runs here, which is why it needs no
# reviewer approval and why a PR cannot edit its own teardown to reach secrets.

🩺 Stability & Availability | Minor | ⚡ Quick win

Workflow-level concurrency can drop a queued teardown.

Every labeled, synchronize and reopened event creates a run that claims the relay-preview-<n> group, even when the job if is false. relay-preview-cleanup.yml uses a job-level group for this reason.

Assume a deploy run is waiting for approval or still running, and a user removes the label. The cleanup job then queues in the same group. If the user pushes a new commit, a new deploy run queues in that group. GitHub replaces the pending cleanup job with it, so the teardown is canceled. The label is already gone, so the nightly retry never lists the PR. The pr-<n> stage leaks until someone removes it by hand.

Move the group to the job, so a skipped job does not take the pending slot.

Move the concurrency group from workflow level into the deploy_preview job so
skipped jobs do not claim a pending slot; preserve the existing group expression
and cancel-in-progress setting.

🔒 Security & Privacy | Major | 🏗️ Heavy lift

The relay-preview environment gate does not protect repository-level secrets.

This workflow runs on pull_request for same-repository PRs, so GitHub uses the workflow file from the PR head. A user with write access can push a branch that changes this file and removes environment:. They can also drop the label check and add any step they want. The job then starts without approval and still receives repository-level secrets.

docs/operations/release.md lists CLOUDFLARE_API_TOKEN, PLANETSCALE_API_TOKEN_ID, PLANETSCALE_API_TOKEN and AXIOM_TOKEN as repository secrets. These secrets are therefore readable without approval. The reviewer gate only protects secrets that are defined in the environment.

Move the secrets this workflow uses into the relay-preview and relay-preview-cleanup environments only. Use preview-scoped credentials that are separate from the prod credentials. Remove the repository-level copies, and update deploy-relay.yml to read the prod credentials from the production environment. The PR description already lists this as a known gap. Close it before the label-gated flow can be treated as approval-protected.

Based on learnings: "flag reliance on Environment required reviewers as their sole safeguard: the actor can omit environment: and still access repository secrets".

Review comment at @.github/workflows/relay-preview.yml around lines 77 - 81:
Update the secret configuration used by the relay preview workflows so preview
credentials are available only through the protected relay-preview and
relay-preview-cleanup environments, not as repository-level secrets. Keep
preview credentials separate from production credentials, and have
deploy-relay.yml read production credentials from the production environment.
