Ships the canonical label set and the classifier that labels newly-filed issues.

Additive only — never removes a label, never overrides a human's classification, silent when unsure, 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 none.

See docs/LABELS.adoc in hyperpolymath/.git-private-farm.

Review Change Stack

📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Added an automated issue-label classification system using titles, tags and issue content.
    • Introduced a consistent label catalogue covering types, areas, priorities, statuses, metadata and scope.
    • Added automatic label synchronisation to keep repository labels aligned with the catalogue.
    • Existing labels are preserved, and uncertain classifications are skipped to avoid incorrect changes.

Walkthrough

The change adds a versioned label catalogue, a jq issue classifier, an issue triage workflow, and a scheduled label synchronisation workflow. The workflows use gh and jq, preserve existing labels, and handle missing or partial operations without unnecessary failures.

Changes

Label automation

Layer / File(s) Summary
Label taxonomy and rules
.github/labels.json, .github/label-classifier.json
Defines canonical labels, classification signals, tier limits, frozen labels, and precedence values.
Issue classification engine
.github/scripts/classify-issue.jq
Normalises titles, resolves prefix and bracket rules, detects keyword signals, enforces tier limits, preserves existing labels, and emits confident canonical labels.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies newly opened or reopened issues, filters results to repository labels, and applies labels additively.
Repository label synchronisation
.github/workflows/labels.yml
Creates missing labels, updates non-frozen label drift, skips existing frozen labels, and reports mutation results.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 7ad35

The PR adds automated repository-wide label mutations and issue triage, but unresolved race conditions and branch-scope and failure-handling issues could apply stale or conflicting labels, while classifier errors may be hidden and metadata may drift. The PR should not merge until these issues are fixed or explicitly accepted.

Pull Request Overview

While this PR successfully adheres to Codacy quality standards, it contains a critical logic error in the triage workflow and is missing necessary configuration for the estate's security policies. Specifically, the shell command used to edit issue labels is vulnerable to word splitting, which will cause failures for any label names containing spaces.

Furthermore, the classification logic relies on complex JQ and regular expressions that are currently untested within the repository's CI/CD pipeline. Given the goal of estate-wide rollout, the lack of unit tests for the 7 required classification scenarios represents a high risk. Finally, there is a discrepancy between the PR description and the provided file list regarding the .github/workflows/actions.lock file; if this file is not updated, the new workflows will fail to start.

About this PR

  • The PR description states that '.github/workflows/actions.lock' was updated, but the file is missing from the PR. In environments with strict action locking, this will cause 'startup_failure' for the new 'labels.yml' and 'label-triage.yml' workflows.

Test suggestions

  • Classification of an issue based on a conventional commit prefix (e.g., 'fix: bug in parser')
  • Classification of an issue based on bracketed tags (e.g., '[p0][security] Title')
  • Keyword-based classification for specific areas (e.g., 'workflow' mapping to 'cicd')
  • Tier enforcement: ensuring only one 'type' label is suggested even if multiple keywords hit
  • Human override protection: classifier skips tiers where a label already exists
  • Label sync creates a missing 'frozen' label (e.g., 'security')
  • Label sync skips updating the definition (color/description) of an existing 'frozen' label
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Classification of an issue based on a conventional commit prefix (e.g., 'fix: bug in parser')
2. Classification of an issue based on bracketed tags (e.g., '[p0][security] Title')
3. Keyword-based classification for specific areas (e.g., 'workflow' mapping to 'cicd')
4. Tier enforcement: ensuring only one 'type' label is suggested even if multiple keywords hit
5. Human override protection: classifier skips tiers where a label already exists
6. Label sync creates a missing 'frozen' label (e.g., 'security')
7. Label sync skips updating the definition (color/description) of an existing 'frozen' label

🟡 MEDIUM RISK

The command expansion will fail for labels containing spaces because the shell performs word splitting on the unquoted result of the substitution. Use a Bash array to safely build and expand the arguments.

Refactor the label application logic in the triage workflow to use a Bash array for building the arguments to gh issue edit (e.g., args+=('--add-label' "$label")), ensuring that labels with spaces are correctly handled without relying on printf %q inside a command substitution.

🟡 MEDIUM RISK

Suggestion: This script contains complex regex-based classification logic. Since the project environment bans Python, parity tests cannot run in this repository's CI. Consider adding a JQ-based test suite to ensure titles are classified correctly.

Create a standalone test script for .github/scripts/classify-issue.jq using bash. The script should iterate over a JSON object of test cases (issue title -> expected labels) and verify that jq -f .github/scripts/classify-issue.jq produces the correct output for each title, failing the CI if any mismatch occurs.

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.

119-162: A jq test suite is still absent.

This concern was already raised on a previous commit. The classification logic here has many branches: bracket, prefix, keyword type, tier limits, and locked tiers. A bash harness that feeds titles and have arrays into jq -f .github/scripts/classify-issue.jq would pin this behaviour without introducing a Python file.

Resolve the security catalogue/frozen overlap.

security has canonical metadata in .github/labels.json and also appears in frozen. The workflow creates missing frozen labels but skips updates for existing frozen labels. Existing security labels can therefore retain colour or description drift indefinitely. Remove security from frozen, or remove it from labels if humans own its complete definition.

Add a per-issue concurrency group.

Two runs can overlap for one issue: an opened event followed quickly by reopened, or a workflow_dispatch during an event run. Both runs read HAVE at lines 82-83 before either run writes at line 114. Each run then sees a state without the other run's label.

The comment at lines 78-81 narrows this window inside a single run, but it cannot close it across runs. The max-1 tier lock at lines 154-157 of .github/scripts/classify-issue.jq depends on HAVE being current, so two overlapping runs can place two labels in the same max-1 tier, for example two type labels. A concurrency group serialises the read-modify-write.

Do not discard classifier stderr.

Line 88 sends jq stderr to /dev/null. A malformed label-classifier.json, a jq syntax error, and a genuine "no confident classification" all produce the same empty output and the same log line at line 90. A future classifier change can then break silently in every repository.

Keep the run green, but record the failure in the log.

GitHub Actions control workflow concurrency cancel-in-progress concurrency group at most one running one pending official documentation

💡 Result:

In GitHub Actions, the concurrency group feature is designed to limit the number of concurrent workflows or jobs [1][2]. By default, each concurrency group allows at most one running job or workflow and one pending job or workflow at any time [1][3]. When a new workflow or job is queued for a concurrency group: - If another job or workflow is currently in progress within that same group, the new job or workflow will be placed in a pending state [1][4]. - By default, if there is already an existing pending job or workflow in that same group, it will be canceled, and the newly queued job or workflow will take its place [1][5]. - You can change this behavior by using the optional queue property (e.g., set to max) to allow up to 100 jobs or workflows to wait in the queue before additional ones are canceled [1][3]. To further control active execution, you can use the cancel-in-progress setting [1][2]: - Setting cancel-in-progress: true will cause any currently running job or workflow in the same concurrency group to be canceled when a new one is queued [1][6]. - By default (or when set to false), running jobs are not canceled, allowing them to complete while the new job stays pending [1][6]. Note that concurrency groups are scoped at the repository level; if multiple workflows use the same concurrency group name, they will be subject to these limits collectively [1][3].

Serialize updates to the repository label set.

The workflow reads existing once, then applies label mutations. Overlapping runs can apply an older catalogue after a newer run and restore stale label metadata. Add a repository-wide concurrency group with cancel-in-progress: true.

Do not fail the workflow for one failed mutation.

If one label is the only required mutation and its gh label create or gh label edit call fails, failed becomes 1 while created + updated remains 0. Line 101 then exits with status 1. This conflicts with the stated policy that one flaky label must not fail the estate. Validate target and token configuration separately, then report individual label failures without failing the workflow.

In @.github/workflows/labels.yml around lines 101 - 103, Update the label-sync
workflow’s failure handling around the failed, created, and updated counters so
an individual gh label create or edit failure does not exit the workflow,
including when it is the only mutation. Validate GH_REPO and token configuration
separately, while continuing to report each label mutation failure and reserving
nonzero exits for invalid target or authentication configuration.
