Prerequisite for enabling the merge queue in this repository.

A queued pull request only merges once its required checks report on the
merge_group event, and neither workflow here ran on that event. The check
names GitHub derives from reusable-workflow jobs also differ between
repositories (build / build here, build-and-test / build elsewhere), so
there was no single context a shared ruleset could require.

Both workflows gain a merge_group trigger and an aggregator job that fails if
anything it depends on failed or was cancelled. The resulting checks,
All checks passed and Lint passed, are named the same in every ShipSoft
repository, so one ruleset covers them all.

A skipped job counts as a pass. commit-check only runs on pull_request
events, so it is skipped inside a merge group and commit messages are checked
on the pull request rather than again in the queue.

The ruleset that requires these checks lives in
ShipSoft/.github/repo-config/.
apply-repo-config.sh refuses to apply it until both checks have reported here
and their workflows have a confirmed merge_group trigger, so this has to land
first.

Summary by CodeRabbit

  • Chores
    • Added merge queue validation for build, test, and lint workflows.
    • Added consolidated status checks that clearly report when required validation jobs fail or are cancelled.

Merge queues are being enabled across ShipSoft. A queued pull request only
merges once its required checks report on the merge_group event, and neither
workflow here ran on that event. The check names GitHub derives from
reusable-workflow jobs also differ between repositories, so there was no
single context a shared ruleset could require.

Add a merge_group trigger to both workflows, and an aggregator job to each
that fails if anything it depends on failed or was cancelled. The resulting
checks, "All checks passed" and "Lint passed", are named the same in every
repository, so one ruleset covers them all.

A skipped job counts as a pass. That is deliberate: commit-check only runs on
pull_request events, so it is skipped inside a merge group and commit messages
are checked on the pull request rather than again in the queue.

📝 Walkthrough

Walkthrough

The build and lint workflows now run on merge queue events. Each workflow adds an aggregate job that reports failure when a required job fails or is cancelled.

Changes

CI status checks

Layer / File(s) Summary
Merge queue workflow triggers
.github/workflows/build-test.yml, .github/workflows/lint.yml
Both workflows now include the merge_group trigger.
Aggregate check jobs
.github/workflows/build-test.yml, .github/workflows/lint.yml
Each workflow adds an always-running aggregate job. The job fails when any required job fails or is cancelled. The lint job is named Lint passed.

Merge-queue runs will execute commit-check even though it is intended only for pull requests. Add the event condition before merging to preserve the CI workflow contract.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Limit commit-check to pull request events.

When merge_group starts this workflow, commit-check is eligible because the job has no event condition. This violates the workflow contract. Add if: github.event_name == 'pull_request' to commit-check. The all-checks job will still run and accept the skipped result.
