feat(labels): estate label tooling + auto-triage for new issues - #119
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe change adds a canonical GitHub label catalogue, title classification rules, a jq classifier, and workflows for issue triage and label synchronisation. ChangesLabel automation
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The new label automation can race, silently skip synchronization errors, add conflicting labels from stale state, and modify issues marked not to be automated. The PR is otherwise mergeable with explicit owner awareness and follow-up for these bounded workflow-correctness risks. Sequence Diagram(s)sequenceDiagram

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.

existing-label gh api read fail the job rather than yielding an empty existing
set; ensure both reads complete successfully before any label mutation occurs.

Revalidate labels immediately before mutation.
Line 82 reads a label snapshot before classification and filtering. If a human adds enhancement after that read for an issue titled fix: ..., Line 114 can add bug from stale input. The issue then has two type labels despite the max-one tier contract.
Move the HAVE read and classification as close as possible to gh issue edit, and re-run the classifier from that refreshed label set before building edit_args.

GitHub Actions official documentation concurrency workflow runs same concurrency group cancel-in-progress false
💡 Result:
In GitHub Actions, the concurrency setting dictates how multiple workflow runs or jobs within the same concurrency group behave when triggered simultaneously [1][2]. When you set cancel-in-progress: false (which is the default behavior if not specified), GitHub Actions manages queued runs as follows: 1. Running Jobs: Jobs currently in progress are protected and will not be canceled by new incoming workflow runs [3]. 2. Queued Jobs: By default, the system allows only one pending (queued) job per concurrency group [1][4]. If a new workflow run is triggered while a job is already queued in that group, the existing pending job is canceled and replaced by the new run [1][3]. As of May 2026, GitHub introduced the ability to allow larger queues for concurrency groups [5]. You can now configure a concurrency group to hold up to 100 queued runs by adding queue: max to your concurrency block [5]. This allows pending runs to wait in line and execute sequentially rather than being automatically canceled [4][5]. Configuration Example: To use the larger queue feature (preventing cancellation of queued runs), you can use: concurrency: group: my-group-name cancel-in-progress: false queue: max Important Notes: - The cancel-in-progress setting specifically governs running jobs, not queued ones [3]. - Combining queue: max with cancel-in-progress: true is not supported and will result in a validation error [6][2]. - Always ensure your concurrency group names are scoped (e.g., using ${{ github.workflow }}-${{ github.ref }}) if you want to avoid unintentional cancellations across different workflows in the same repository [1][2].

Serialise label synchronisation runs.
These triggers can overlap. Each run reads the labels once at .github/workflows/labels.yml:58-59, then applies mutations from that snapshot. An older run can finish after a newer run and restore an outdated colour or description. Concurrent creates can also produce spurious failures.
Add a repository-scoped workflow concurrency group with cancel-in-progress: false.

Fail on payload or label-list read errors.
Line 52 maps fetch, API, and decoding failures to the successful no-op at line 53. Line 58 also leaves existing empty when gh api fails because the script does not enable errexit. The workflow can then create a missing label, exit successfully at line 101, and leave existing labels unchanged. Distinguish an intentional missing payload from other errors, validate the JSON, and fail before mutation when either read fails.
