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 automatic classification and labelling for newly opened or reopened issues.
    • Introduced a standardised catalogue of issue labels covering type, area, priority, status, metadata and scope.
    • Added scheduled label synchronisation to create and update labels while preserving frozen labels.
    • Labels are applied additively without removing existing manually assigned labels.

Walkthrough

Adds a canonical GitHub label catalogue, jq-based issue classification, automatic triage for new or reopened issues, and scheduled label synchronisation. The workflows add labels without deleting existing labels and preserve frozen labels.

Changes

Label automation

Layer / File(s) Summary
Label taxonomy
.github/label-classifier.json, .github/labels.json
Defines 37 labels, classification rules, tier limits, frozen labels, and precedence ordering.
Issue classification
.github/scripts/classify-issue.jq
Normalises titles, resolves bracket and prefix rules, detects keyword signals, enforces tier limits, and prints applicable labels.
Issue triage workflow
.github/workflows/label-triage.yml
Classifies opened or reopened issues and adds matching repository labels without removing existing labels.
Label catalogue synchronisation
.github/workflows/labels.yml
Creates missing labels, updates colour and description drift, and skips frozen labels on configured triggers.

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

Merge Risk: 🟠 High · up to b669d

This PR adds automatic label synchronization and issue triage, but two failure paths can currently report success with stale or incomplete labels or classify an issue from an empty label set, potentially overriding a human classification; merge should be blocked until failed reads are handled explicitly. Concurrency, permission scope, and ambiguous keyword matching also require owner follow-up.

Poem

A rabbit checks each label line,
And sorts the tags in neat design.
jq hops through titles, quick and bright,
Workflows keep the catalogue right.
Frozen marks stay safe and still.

🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Add a per-issue concurrency group and document the write permission.

Two runs can target the same issue: opened followed quickly by reopened, or a workflow_dispatch while the event-driven run is still active. Both runs read HAVE before either writes, so each can add a different label in the same max-1 tier. The lockedtiers guard in .github/scripts/classify-issue.jq cannot see the other run's write. A concurrency group serialises the read-then-write window.

The same block also answers zizmor's undocumented-permissions warning.

Pull Request Overview

While the PR successfully implements the estate-wide requirements of avoiding Python and external GitHub Actions, it currently contains a critical syntax error in the JQ script that will prevent the triage workflow from functioning. Additionally, there is a shell-scripting bug that will cause failures when applying label names containing spaces.

Codacy analysis reports the code is up to standards, but there is a significant gap in verification; none of the required test scenarios for the classification logic (prefixes, bracketed tags, or additive-only behavior) were addressed in this diff. The PR also bypasses standard source auditing by fetching script content via the GitHub API instead of using checkout actions.

About this PR

  • The triage logic in classify-issue.jq is complex and lacks unit tests. Given the strict additive-only policy and the use of regex for natural language processing, automated tests are necessary to verify edge cases such as suffix matching and precedence.
  • The practice of fetching script content via gh api ... | base64 -d in CI bypasses standard source auditing and security analysis tools. Ensure this deviation from standard actions/checkout usage is approved for estate-wide deployment.

Test suggestions

  • Missing recommended test scenario: Issue title with conventional commit prefix (e.g., 'feat:...') triggers 'enhancement' label application.
  • Missing recommended test scenario: Issue title with bracketed tag (e.g., '[docs]...') triggers 'documentation' label application.
  • Missing recommended test scenario: Classifier respects existing 'type' labels and does not add a second conflicting type (e.g., adding 'bug' to an issue already labeled 'enhancement').
  • Missing recommended test scenario: Classifier returns an empty result when no confident 'type' can be matched from keywords or prefixes.
  • Missing recommended test scenario: Label sync workflow updates color/description for existing labels but ignores those listed in the 'frozen' array.
  • Missing recommended test scenario: Workflows correctly fetch configuration and script payloads via GitHub API without using actions/checkout.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Missing recommended test scenario: Issue title with conventional commit prefix (e.g., 'feat:...') triggers 'enhancement' label application.
2. Missing recommended test scenario: Issue title with bracketed tag (e.g., '[docs]...') triggers 'documentation' label application.
3. Missing recommended test scenario: Classifier respects existing 'type' labels and does not add a second conflicting type (e.g., adding 'bug' to an issue already labeled 'enhancement').
4. Missing recommended test scenario: Classifier returns an empty result when no confident 'type' can be matched from keywords or prefixes.
5. Missing recommended test scenario: Label sync workflow updates color/description for existing labels but ignores those listed in the 'frozen' array.
6. Missing recommended test scenario: Workflows correctly fetch configuration and script payloads via GitHub API without using actions/checkout.

🔴 HIGH RISK

The jq expression has unbalanced parentheses. There are three opening parentheses and only two closing ones before the as $matched assignment, which will cause a parse error at runtime.

🟡 MEDIUM RISK

Using $(printf ... %q) relies on shell word splitting, which fails if any label names contain spaces (common in the 'frozen' list). Replace the gh issue edit logic with a Bash array implementation to safely handle these labels.

⚪ LOW RISK

Suggestion: The check for existing type labels at line 140 only recognizes labels defined in the global .github/label-classifier.json. If a repository uses custom type labels not in this set, the classifier will not recognize them as types and may add a redundant canonical type label, violating the 'no-override' goal.

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.

Replace or review short keywords that use inflection-tolerant matching

kwhit enforces an alphanumeric boundary on the left and after the optional suffix. Therefore, port does not match support, report or important, and add does not match address.

However, the matcher permits suffixes such as d, s and es. Consequently, hol matches hold and holes. Review short keywords such as hol and test for unintended matches, or use unambiguous phrases where necessary.

Do not classify when the existing-label read fails.

|| HAVE='[]' treats a failed gh issue view call as an empty-label response. The classifier then skips its max-1 tier locks. For example, a fix: issue can receive bug even when a human already applied enhancement. Exit before the jq call when the label read fails.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Serialize overlapping runs and narrow token permissions in both label workflows.

labels.yml can overlap push, scheduled, and manual runs, allowing concurrent reads to produce duplicate create attempts and false failure counts. Add a workflow-level concurrency group there. label-triage.yml needs a per-issue concurrency group so concurrent events do not classify from stale label data.

Move issues: write and contents: read from workflow scope to the individual jobs in both workflows to reduce unnecessary token exposure.

Guard the existing fetch; an empty result silently disables all drift repair.

set -e is not active, so a failed or truncated gh api ... labels --paginate leaves existing empty and the step continues. Line 66 then finds no current label, so every name takes the create branch. Each create fails with "already exists".

If at least one canonical label is genuinely missing, created is greater than 0. The exit rule on line 101 requires created + updated to equal 0, so the step exits 0. Colour and description drift is skipped for every existing label, and the run reports success. Fail fast when the read does not succeed.

🐛 Proposed fix
-          existing=$(gh api "repos/$GITHUB_REPOSITORY/labels" --paginate \
-                       --jq '.[] | [.name, .color, (.description // "")] | `@tsv`')
+          # LOAD-BEARING: an empty or partial read makes every label look
+          # missing, which turns the whole run into create-only churn and hides
+          # all colour/description drift behind a green check.
+          if ! existing=$(gh api "repos/$GITHUB_REPOSITORY/labels" --paginate \
+                            --jq '.[] | [.name, .color, (.description // "")] | `@tsv`'); then
+            echo "cannot list existing labels - refusing to sync blind"
+            exit 1
+          fi
