ci: harden trunk gating by kjgbot · Pull Request #488 · AgentWorkforce/relaycast

kjgbot · 2026-10-08T23:04:58Z

Hardens the trunk-only CI gating per review on AgentWorkforce/relay#1932: head repo + base branch checks in every gate; guard via pull_request_target with edited; closed-only workflows ungated.

🤖 Generated with Claude Code

Note

Low Risk
Workflow-only changes that restrict when CI runs and strengthen merge policy; no application or secrets logic changes.

Overview
Tightens trunk → main CI so expensive jobs only run when the PR is this repo’s trunk branch targeting main, not merely when the head ref is named trunk (e.g. forks or wrong bases).

The shared job if in CI, container-integration, and preview cleanup now requires github.event.pull_request.head.repo.full_name == github.repository and github.base_ref == 'main' alongside github.head_ref == 'trunk'.

Trunk guard switches to pull_request_target (with edited), empty permissions, and fails when the head isn’t trunk or the head repo isn’t the upstream repository—so the guard runs from base-branch workflow code and blocks fork or non-trunk merges into main.

- CI gates also require the head repo to be this repository and the base to be main (a fork branch named trunk, or trunk into another branch, no longer runs CI). - Trunk guard runs via pull_request_target (loaded from the base branch, so a PR cannot edit it to pass), re-runs on base edits, and checks head repo. - Workflows that only react to a PR closing are no longer gated.

🟡 Closed preview workers remain deployed

When a feature PR with a preview worker closes, cleanup-preview skips deletion because its head is not trunk. The worker remains deployed after the PR closes.

Learn more

Preview workers were previously deployed for same-repository feature PRs by the deploy-preview job before trunk gating removed it. The current cleanup job runs only on closed events, but the trunk-only predicate discards those events for feature PRs. The remaining predicate already restricts deletion to same-repository PRs, and a closed PR always has a closed state. This leaves previously deployed workers active unless the separate audit runs in removal mode.

Example: PR #400 deployed relaycast-pr-400 before trunk gating. Closing PR #400 from feature/search skips cleanup, leaving the worker active instead of deleting it.

Recommended fix: Gate cleanup-preview only on a closed event from the same repository. Keep the existing same-repository restriction and delete both worker names as before.

Closed cleanup remains trunk-gated

Medium Severity

cleanup-preview still requires a same-repo trunk → main pull request, so closing any other PR skips teardown. This change was supposed to ungate closed-only workflows, but the job kept the trunk gate and added base_ref plus head-repo checks.
