feat(labels): estate label tooling + auto-triage for new issues - #46
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a canonical GitHub label configuration, a jq issue classifier, and workflows that synchronise labels and apply additive labels to newly opened or reopened issues. ChangesGitHub label automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The change is mergeable with follow-up: label synchronization can silently skip updates after a fetch or decode failure, concurrent runs can fail despite the repository being correct, and generic regression reports may receive an inaccurate performance label.

Ships the canonical label set and the classifier that labels newly-filed issues. Additive only: it never removes a label, never overrides a human's classification, stays silent when unsure, and never fails an issue. Also adds this repo's two new workflows to .github/workflows/actions.lock as '[]'. That lock is keyed by workflow path and refuses any workflow it does not list -- a startup_failure, which produces no check run and is therefore silent. `gh actions-lock` cannot add these: it records action versions, and both workflows deliberately use no actions.

Remove the generic regression performance signal.
A title such as fix: parser regression emits both bug and performance. A generic regression does not establish a performance concern. Remove regression, or replace it with a specific phrase such as performance regression.

GitHub CLI gh label create already exists error documentation GitHub Actions concurrency group cancel-in-progress false workflow
💡 Result:
When using the GitHub CLI (gh) to create a label, you may encounter an error if the label already exists [1][2]. To handle this, use the --force flag with the gh label create command [3][4]. This flag allows the command to update an existing label's color and description if the name already exists, rather than failing with an "already_exists" (HTTP 422) error [3][5][4]. Regarding GitHub Actions concurrency with cancel-in-progress: false: 1. Behavior: When cancel-in-progress is set to false (which is the default), any currently running job in the concurrency group is protected and will be allowed to complete [6][7]. However, if there is already a job in the queue (pending state) for that same concurrency group, it will be canceled and replaced by the new incoming run [8][6][9]. 2. Queueing: As of May 2026, GitHub Actions allows for larger queues within concurrency groups [10]. You can now enable support for up to 100 queued jobs per concurrency group by specifying queue: max in your concurrency block when cancel-in-progress is set to false [10]. This prevents the standard behavior where only one pending job is allowed to wait at a time [10][6]. In summary, cancel-in-progress: false ensures that active, running jobs are not interrupted, but it does not inherently prevent the replacement of queued (pending) jobs unless you configure the newer queuing features [10][6][7].

Serialise label mutation runs.
When two runs read the same missing label, both can call gh label create. One call can fail with an already_exists error after the other run creates the label. If every mutation in that run fails, Lines 101–103 fail the workflow even though the repository is correct. Add a workflow-level concurrency group, such as labels-${{ github.repository }}, with cancel-in-progress: false.

Do not report a fetch failure as an absent configuration.
|| true masks contents API and Base64 decode failures. The next check then exits successfully with no .github/labels.json - nothing to do, so label synchronisation does not run. Fail the job when the canonical payload cannot be fetched or decoded.
