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.

📝 Walkthrough

Summary by CodeRabbit

  • New Features
    • Added automatic issue labelling based on titles, descriptions, keywords and status signals.
    • Added consistent label categories, priorities and scopes while preserving protected labels.
    • Added automatic synchronisation of canonical labels, including descriptions and colours.
    • Label processing runs when issues are opened or reopened, on demand, and on a regular schedule.
  • Bug Fixes
    • Invalid, unavailable or uncertain classifications are safely skipped without failing the workflow.

Walkthrough

Adds generated label contracts, a jq issue classifier, an event-driven triage workflow, and a scheduled label synchronisation workflow. The workflows use repository configuration and GitHub APIs without third-party actions.

Changes

Issue label automation

Layer / File(s) Summary
Label contracts and classification rules
.github/label-classifier.json, .github/labels.json
Adds generated mappings for title prefixes, bracket tags, keywords, signals, tiers, precedence, label metadata, and frozen labels.
Issue classification pipeline
.github/scripts/classify-issue.jq
Normalises issue titles, extracts explicit and keyword signals, applies precedence and tier limits, preserves existing labels, validates results, and emits suggested labels.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies new and reopened issues, validates suggested labels, applies additive changes, and exits successfully when classification or API operations cannot proceed.
Canonical label synchronisation
.github/workflows/labels.yml
Creates missing labels, updates non-frozen metadata drift, preserves frozen labels, and runs on manual, file-change, and monthly triggers.

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

Merge Risk: 🟡 Moderate · up to a2538

The new automation can misreport label-service failures, modify issues that explicitly opt out, and race when multiple runs handle the same repository or issue, potentially causing false failures or duplicate labels. These bounded correctness and maintenance risks remain unresolved, so merge should wait for fixes or explicit owner acceptance.

Pull Request Overview

While the PR is technically 'up to standards' according to Codacy, it contains a critical logic error in the .github/scripts/classify-issue.jq script. The use of capture without fallback handling causes the classification pipeline to halt for any issue that doesn't strictly match the bracketed tag format, preventing the fallback to conventional commit prefixes or keyword matching. This effectively breaks the auto-triage for a large subset of potential issues.

Additionally, there is a significant discrepancy between the PR description and the provided files: the mentioned .github/workflows/actions.lock and tests/test-classifier-parity.py are missing from the diff. This is particularly concerning as the logic is complex and currently has zero coverage. The implementation should not be merged until the logic bugs are resolved and the missing test infrastructure is provided.

About this PR

  • The documentation and code comments reference a parity test (tests/test-classifier-parity.py) which is not present in the PR. Given the complexity of the jq logic, these tests are necessary for verification.
  • The PR description states that .github/workflows/actions.lock was updated, but this file is missing from the provided diff. Please ensure all intended changes are staged and pushed.

Test suggestions

  • Missing recommended test scenario: Verify conventional commit prefixes (e.g., 'feat: ') result in 'enhancement' label
  • Missing recommended test scenario: Verify bracket tags (e.g., '[p0]') result in 'priority:p0' label
  • Missing recommended test scenario: Verify keyword matching for specialized areas (e.g., 'coq' or 'agda' triggers 'proofs')
  • Missing recommended test scenario: Verify that human-applied labels block auto-labeling for the same tier
  • Missing recommended test scenario: Verify label sync creates missing labels and updates existing ones
  • Missing recommended test scenario: Verify label sync skips labels defined in the 'frozen' list
  • Missing automated unit tests for inflection-tolerant regex logic in .github/scripts/classify-issue.jq
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Missing recommended test scenario: Verify conventional commit prefixes (e.g., 'feat: ') result in 'enhancement' label
2. Missing recommended test scenario: Verify bracket tags (e.g., '[p0]') result in 'priority:p0' label
3. Missing recommended test scenario: Verify keyword matching for specialized areas (e.g., 'coq' or 'agda' triggers 'proofs')
4. Missing recommended test scenario: Verify that human-applied labels block auto-labeling for the same tier
5. Missing recommended test scenario: Verify label sync creates missing labels and updates existing ones
6. Missing recommended test scenario: Verify label sync skips labels defined in the 'frozen' list
7. Missing automated unit tests for inflection-tolerant regex logic in `.github/scripts/classify-issue.jq`
Low confidence findings
  • The triage workflow utilizes gh api to fetch the classifier script and rules dynamically. If this API call fails (e.g., due to rate limiting or auth issues), the workflow exits silently. Consider adding a check to fail the workflow or log a clear error message if the resources cannot be retrieved.

🔴 HIGH RISK

Wrap the capture in an array and use .[0] to ensure the pipeline continues with null when no prefix match is found. Without this, issues without a conventional commit prefix will fail to reach the keyword matching logic.

🔴 HIGH RISK

The use of capture causes the pipeline to halt if no match is found, preventing execution of subsequent classification logic. Wrap the expression in an array and take the first element (e.g., [capture("...")] | .[0]) to ensure a null is produced on failure instead of halting the stream.

🟡 MEDIUM RISK

Suggestion: The inflection-tolerant regex generation logic in kwrx is complex and relies on specific stem endings. To ensure reliability and prevent false positives (e.g., 'port' matching 'portion'), consider implementing a dedicated test suite for these functions using jq test syntax or a shell wrapper.

Suggestion: Silencing stderr prevents visibility into why a label might fail to be created or updated (e.g., API permissions or rate limits). Since the script already checks for label existence, stderr should be preserved for observability.

Honour status:do-not-automate before classification.

If HAVE contains status:do-not-automate, exit successfully before the workflow classifies or edits the issue. A manually dispatched issue with that label and a title such as fix: parser fails currently receives bug, despite the label contract stating that bots and sweeps must not touch it.

Distinguish an empty label list from a failed label read.

gh label list sends errors to /dev/null, so an API failure produces an empty DEFINED array. The run then reports this repo defines none of them - run the label sync, which points a maintainer at the label sync instead of the transient API failure. Report the two cases separately.

Proposed fix
           mapfile -t DEFINED < <(gh label list -R "$GITHUB_REPOSITORY" --limit 1000 \
                                    --json name --jq '.[].name' 2>/dev/null)
+          if [[ ${`#DEFINED`[@]} -eq 0 ]]; then
+            echo "could not read this repo's labels - not classifying"
+            exit 0
+          fi

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Serialize concurrent label workflow runs.

The label synchronizer and issue triage workflow can overlap. Two runs may read the same state before either writes: synchronization can report a false mutation failure, while triage can apply two labels from the same max-one tier. Add repository- and issue-scoped concurrency groups with cancel-in-progress: false so conflicting runs queue instead of overlapping.

The same overlap risk applies to concurrent events or manual dispatches for one
issue; use an issue-number-scoped concurrency group.
