Pull Request Overview
The PR implements a label taxonomy and automated triage system using native GitHub CLI and JQ, successfully adhering to the constraint of avoiding external GitHub Actions to prevent lockfile drift. While Codacy reports the changes are up to standards, there is a critical discrepancy: the PR description mentions a test suite (tests/test-classifier-parity.py) and lockfile updates that are missing from the current diff.
The classification logic implemented in JQ is sophisticated, covering conventional commits and tier constraints, but it is currently unverified within the codebase. Furthermore, the label synchronization workflow contains an inefficiency that causes unnecessary delays during no-op runs. These missing verification scripts and workflow optimizations should be addressed before merging.
About this PR
- The PR description references a test suite (
tests/test-classifier-parity.py) and lockfile updates, but these files are not included in the PR. Please ensure all intended assets are committed. - The complex JQ classification logic lacks accompanying verification scripts. Without the 'test-classifier-parity.py' mentioned in the description, there is no automated way to ensure classification accuracy or adherence to tier constraints.
Test suggestions
- Classification via conventional commit prefix (e.g., 'feat: ...')
- Classification via bracket tags (e.g., '[p0] ...')
- Area assignment from title keywords (e.g., 'z3' triggering 'proofs')
- Mandatory 'type' label enforcement logic
- Prevention of multiple labels within a max-1 tier (tier_max: 1)
- Preservation of existing human-applied labels during triage
- Idempotent label synchronization (creation of missing labels)
- Protection of 'frozen' label definitions during sync

⚪ LOW RISK
Suggestion: Move the sleep 0.4 call inside the if blocks for gh label create and gh label edit. Currently, it executes for every label defined in the taxonomy, causing significant mandatory delay even when labels are already perfectly synced. Relocating it ensures the workflow only waits when a mutation occurs, respecting secondary rate limits without wasting time on skipped labels.

⚪ LOW RISK
Nitpick: Use printf -- '%s\n' "$existing" to safely handle strings that might start with a hyphen, preventing the shell from interpreting the value as a command flag.
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.

Do not continue with an empty label set after a failed label read.
The fallback assigns HAVE='[]' when gh issue view fails. The classifier can then add a type, priority, status, meta, or scope label that already exists on the issue. This breaks the additive-only contract and can override a human classification.
Exit without changes when the label read fails or does not produce a JSON array.

Honour status:do-not-automate before classification.
An issue with status:do-not-automate can still receive a type or area label. The canonical label definition states that bots and sweeps must not touch these issues. Exit before the classifier and gh issue edit when this label exists.
Proposed fix
echo "already has: $HAVE"
+ if jq -e 'index("status:do-not-automate") != null' >/dev/null <<<"$HAVE"; then

GitHub CLI gh label create existing label exit status documentation
💡 Result:
When using the GitHub CLI (gh) command gh label create, attempting to create a label that already exists will cause the command to fail with an exit status of 1 and an error message typically indicating a 422 HTTP validation error (e.g., Label.name already exists) [1][2][3]. To avoid this failure and make the command idempotent, you can use the --force flag [3][4]. When --force is provided, the command will update the existing label's color and description instead of failing [5][6][4]. This is the recommended practice for automation and CI/CD scripts to prevent errors during repeated executions [3].

Serialise label synchronisation runs.
When concurrent runs both snapshot a label as absent, both enter the gh label create branch. The losing command returns non-zero because the label now exists, and the workflow can fail at Lines 101–103 when it has no successful mutation. Add a repository-scoped concurrency group with cancel-in-progress: false.

site:docs.github.com/en/actions events that trigger workflows push workflow file default branch GITHUB_SHA ref
💡 Result:
In GitHub Actions, when a workflow is triggered, GitHub uses the version of the workflow file that exists at the specific commit SHA or Git ref associated with that event [1][2]. The environment variables GITHUB_SHA and GITHUB_REF are automatically set by GitHub in the runner environment to provide information about the event that triggered the run [1][3]: 1. GITHUB_SHA: This represents the commit SHA that triggered the workflow [4][3]. For a push event, it is the SHA of the commit that was pushed [4][3]. 2. GITHUB_REF: This represents the fully-formed ref of the branch or tag that triggered the workflow [4][3]. For push events, it is the branch or tag ref that was pushed (e.g., refs/heads/main) [4][3]. While most event-driven workflows use the workflow file as it exists in the triggering commit, some specific events require the workflow file to exist on the default branch of the repository in order to trigger at all [1][2]. Examples of such triggers include workflow_dispatch and workflow_run [5][6]. For a push event, the workflow runs using the version of the workflow file present in the pushed commit [1][2]. If you need a workflow to behave differently depending on whether it is running on the default branch versus another branch, you can check the GITHUB_REF variable within your workflow steps or use branch filters in the on configuration [5][7].

Restrict label mutation to the default branch.
The unfiltered push trigger can run when a feature branch changes .github/labels.json. The step fetches that branch commit through GITHUB_SHA and uses its definitions to create or edit repository-global labels. Add a job condition that permits sync only when github.ref matches the default-branch ref.
