Hey @Gareth Brickman Adding

externally-merged

label to the PR before merging worked. I wrote a GH Actions script and we were able to automate this, and the Linear auto-transition is fixed now:

name: Linear - mark externally-merged when queued in Graphite

on:
  issue_comment:
    types: [created]

permissions:
  pull-requests: write

jobs:
  label:
    runs-on: ubuntu-latest
    steps:
      - name: Add externally-merged label
        uses: actions/github-script@v7
        with:
          github-token: ${{ secrets.GITHUB_TOKEN }}
          script: |
            if (!context.payload.issue.pull_request) return;

            const commentAuthor = context.payload.comment.user.login;
            if (commentAuthor !== 'graphite-app[bot]') return;

            const comment = context.payload.comment.body;
            const queuePhrase = 'added this pull request to the [Graphite merge queue]';
            if (!comment.includes(queuePhrase)) return;

            const prNumber = context.payload.issue.number;

            await github.rest.issues.addLabels({
              owner: context.repo.owner,
              repo: context.repo.repo,
              issue_number: prNumber,
              labels: ['externally-merged']
            });

It's not the most robust way of handling it since it could break if the queuePhrase changes, but it works for now at least.

awesome, thanks for sharing!

You're welcome, hope this helps if it comes up with any other customers on your end.
