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 issue labelling based on title and content signals.
    • Added workflows to apply labels to new or reopened issues and synchronise the repository’s label set.
    • Added support for preserving existing and protected labels during automation.
    • Added scheduled and manual options for refreshing repository labels.
    • Added safeguards to apply only recognised, confidently matched labels and continue safely when classification information is unavailable.

Walkthrough

Added JSON label definitions and classifier rules. Added jq-based issue classification and triage. Added workflows that synchronise repository labels on demand, on changes, and monthly.

Changes

Issue label automation

Layer / File(s) Summary
Label and classifier contracts
.github/labels.json, .github/label-classifier.json
Defines 37 repository labels, frozen labels, classification mappings, tier limits, valid types, and precedence rules.
Issue classification and triage
.github/scripts/classify-issue.jq, .github/workflows/label-triage.yml
Classifies issue titles and applies confident, repository-defined labels while preserving existing labels and handling unavailable data without workflow failure.
Repository label synchronisation
.github/workflows/labels.yml
Creates missing labels, updates non-frozen labels when their colour or description differs, and reports mutation counts. Frozen labels are not modified after creation.

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

Merge Risk: 🟡 Moderate · up to 7508c

This change adds automatic repository label updates and issue triage. As written, a feature-branch push could update shared labels before review, and a failed label lookup could trigger incorrect creation attempts and misleading failures; these workflow risks should be fixed or explicitly accepted before merging.

Suggested reviewers: metadatastician

Poem

A rabbit checks each label line,

And sorts the tags in neat design.
The jq paths hop, the workflows run,
Frozen names stay safely done.
New issue clues find homes just right.

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

Harden the label synchronization workflow before merge.

Two independent safeguards are missing:

  1. The push trigger is not restricted to the default branch, so edits to .github/labels.json on any branch can apply label changes before merge. Add a default-branch filter.
  2. The existing-label API call is unchecked. If it fails, the workflow treats all labels as missing, attempts failing creates, reports zero changes, and exits successfully. Handle the listing failure explicitly and refuse to continue.

These changes prevent unreviewed updates and silent synchronization failures.

20-26: 🗄️ Data Integrity & Integration | ⚡ Quick win

Both previously reported safeguards are still missing.

The push trigger at lines 22-24 still has no branches filter, so a change to .github/labels.json on any branch mutates repository labels before review. The gh api .../labels call at lines 58-59 still has no exit-status check, so a failed listing makes every canonical label look absent, turns the run into a series of failing creates, and can end in the misleading every label mutation failed path.

🛠️ Proposed change
   push:
+    branches:
+      - main
     paths:
       - '.github/labels.json'
-          existing=$(gh api "repos/$GITHUB_REPOSITORY/labels" --paginate \
-                       --jq '.[] | [.name, .color, (.description // "")] | `@tsv`')

+                            --jq '.[] | [.name, .color, (.description // "")] | `@tsv`'); then

No colour normalisation is required. .github/labels.json stores its label colours without a leading #, so the comparison already uses matching formats.

312-351: 🎯 Functional Correctness

No change required: keyword matching is boundary-aware.

kwhit uses kwrx, which requires a non-alphanumeric left boundary and a non-alphanumeric right boundary. Therefore, hol, nif, and port do not match within whole, manifest, or support.

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

Move permissions to the job, name the job, and add a per-issue concurrency group.

Three static analysis findings apply, and all three fixes are behaviour-preserving:

  1. issues: write sits at workflow level while only one job needs it. Declare it on the triage job.
  2. The job has no name.
  3. The workflow has no concurrency. A dispatch that runs while the opened event is still in flight can interleave the HAVE read at line 82 with the edit at line 114. The classifier is additive, so the result is a redundant edit attempt rather than a wrong label. A per-issue group closes the window that lines 78-81 describe.
