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 labelling for newly opened and reopened issues based on their titles and content.
    • Added support for synchronising the repository’s label set, including creating missing labels and updating permitted label changes.
    • Added manual and scheduled options for maintaining labels.
  • Improvements

    • Existing labels are preserved, and uncertain classifications are left unchanged.
    • Label management now avoids altering protected labels and handles partial failures safely.

Walkthrough

Adds a generated GitHub label taxonomy, a jq issue classifier, and workflows that synchronise labels and apply additive classifications to issues.

Changes

GitHub label automation

Layer / File(s) Summary
Label taxonomy and classification rules
.github/label-classifier.json, .github/labels.json
Defines 39 labels, classification mappings, signals, tier limits, frozen labels, and precedence values.
jq issue classifier
.github/scripts/classify-issue.jq
Normalises titles, resolves prefixes and bracket tags, detects signals, enforces tier limits, and emits valid labels.
GitHub label workflows
.github/workflows/labels.yml, .github/workflows/label-triage.yml
Synchronises canonical labels and applies classifier results to opened, reopened, or manually selected issues. API and payload failures exit successfully on a best-effort basis.

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

Merge Risk: 🔵 Low · up to 4eafe

The new auto-triage behavior may still add labels to issues marked status:do-not-automate, contrary to the repository’s automation policy. The PR is otherwise mergeable, but this bounded correctness issue should be addressed or explicitly accepted by the owner.

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.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Respect status:do-not-automate before emitting labels.

If an issue already has status:do-not-automate, this function can still emit labels from a prefix, bracket tag, or keyword signal. The triage workflow then modifies an issue that the canonical label definition excludes from bot activity. Return an empty result when $have contains this status label.

Proposed fix
-  | if ($matched | not) then []
+  | if ($have | index("status:do-not-automate")) then []
+    elif ($matched | not) then []
     # a type is mandatory
     elif ((($out + $have) | any(. as $x | $types | index($x))) | not) then []
     else ($out | sort) end;
