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 automated classification for newly opened or reopened issues, applying relevant labels based on titles and existing labels.
    • Added a central label catalogue covering types, areas, priorities, statuses, metadata and scopes.
    • Added automatic synchronisation to create or update repository labels while protecting designated labels.
    • Added manual, scheduled and change-triggered options for maintaining the label set.
    • Human-applied labels are preserved, and uncertain classifications are left unchanged.

Walkthrough

The change adds canonical GitHub label definitions, generated classification rules, a jq-based issue classifier, an issue triage workflow, and a label synchronisation workflow.

Changes

Label automation

Layer / File(s) Summary
Canonical label and classifier data
.github/labels.json, .github/label-classifier.json
Defines label tiers, metadata, frozen labels, title rules, bracket tags, keyword signals, tier limits, and precedence values.
jq issue classification
.github/scripts/classify-issue.jq
Parses issue titles, matches rules and keywords, derives labels, enforces tier limits, and excludes labels already present.
Canonical label synchronisation
.github/workflows/labels.yml
Creates missing labels, updates mutable label metadata, skips frozen existing labels, and reports operation results.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened, reopened, or manually selected issues and applies only defined labels without removing existing labels.

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

Merge Risk: 🟡 Moderate · up to 2c2c5

The workflows can silently skip canonical label synchronization and may treat unreadable existing labels as absent, allowing automated classification to add labels over a human’s classification. This creates a concrete correctness risk, so the PR is not merge-ready until both failure paths are handled safely.

Poem

A rabbit reads the labels bright

jq sorts each tag just right
Workflows hop from issue to queue
Frozen names stay firm and true
New labels bloom in GitHub light
Carrots celebrate the night

Pull Request Overview

While Codacy results indicate the PR is up to standards, there are significant risks concerning the newly introduced automation logic. Specifically, .github/scripts/classify-issue.jq is identified as a complex, high-risk file with 0% test coverage for its sophisticated regex-based classification. This script handles estate-wide label triage, yet the PR is missing the local test suite and generator scripts referenced in its own documentation and file headers. Furthermore, the PR description mentions updates to .github/workflows/actions.lock which are not present in the diff, creating a potential policy violation regarding dependency management. These gaps in testing and verification for high-impact automation logic should be addressed before merging.

About this PR

  • The PR description states that '.github/workflows/actions.lock' was updated, but these changes are not included in the PR diff. Ensure the lockfile is included to satisfy environment constraints and prevent dependency drift.
  • The PR is missing several critical files referenced in the description and code headers: the external test suite ('tests/test-classifier-parity.py') and the generator scripts ('scripts/gen-*.py') required to maintain the JSON configuration files. Please include these or clarify their location.

Test suggestions

  • Classification of issues using conventional commit prefixes (e.g., 'feat:', 'fix:') maps to correct type labels.
  • Classification of issues using bracketed tags (e.g., '[security]') correctly assigns area/meta labels.
  • Keyword-based detection (e.g., 'wasm' or 'ffi' in title) triggers correct area labels.
  • Verification that existing 'type' or 'priority' labels prevent the classifier from adding a second label in the same exclusive tier.
  • Label sync workflow correctly updates modified label descriptions and colors without deleting existing labels.
  • Automatable unit test suite for .github/scripts/classify-issue.jq regex logic against a standard title corpus.

🟡 MEDIUM RISK

This script contains complex regex logic and precedence rules for estate-wide label triage. Since it lacks local test coverage, consider adding a Bash-based test suite that exercises the jq logic against known issue titles (e.g., 'fix: bug', 'feature: [estate] thing') to ensure accuracy and prevent regression.

# A rule must actually have FIRED: keyword-area hits alone are not enough.
| if ($matched | not) then []
# a type is mandatory
elif ((($out + $have) | any(. as $x | $types | index($x))) | not) then []

⚪ LOW RISK

Suggestion: The classifier will return an empty set if a 'type' label is not identified, even if 'area' or 'meta' labels were successfully matched. Ensure this 'type-mandatory' behavior is the desired behavior for all automated triage.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Do not treat a failed label read as an empty label set.

Line 83 converts every gh issue view failure into []. During a transient API failure, an issue that already has enhancement can be classified from fix: and receive bug. This violates the additive-only rule for human classifications.

Exit successfully without mutation when the label read fails or returns no payload.

Proposed fix
-          HAVE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" \
-                   --json labels --jq '[.labels[].name]' 2>/dev/null) || HAVE='[]'
-          [[ -n "$HAVE" ]] || HAVE='[]'
+          if ! HAVE=$(gh issue view "$NUM" -R "$GITHUB_REPOSITORY" \
+                       --json labels --jq '[.labels[].name]' 2>/dev/null); then
+            echo "cannot read existing labels - leaving for a human"
+            exit 0
+          fi
+          if [[ -z "$HAVE" ]]; then

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Fail when canonical label retrieval fails.

At Line 52, || true accepts GitHub API, token, and Base64 decode failures. Line 53 then exits with success and performs no synchronisation. This can leave required labels undefined and prevent downstream triage from applying them.

Proposed fix
-          gh api "repos/$GITHUB_REPOSITORY/contents/.github/labels.json?ref=$GITHUB_SHA" \
-            --jq '.content' 2>/dev/null | base64 -d > "$PAYLOAD" || true
