feat(labels): estate label tooling + auto-triage for new issues - #105

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe change adds generated label taxonomy files, a jq classifier, and GitHub Actions workflows. The workflows synchronise repository labels and add confident labels to newly opened or reopened issues. ChangesLabel automation
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The new labeling workflows can silently skip registry synchronization on API or decoding errors, classify issues from stale labels, and let overlapping runs apply stale metadata. These are bounded correctness and operational risks, so the PR is mergeable with explicit owner awareness and follow-up. Sequence Diagram(s)sequenceDiagram

Serialise label synchronisation runs.
If two push-triggered runs overlap, each uses its own $GITHUB_SHA. A slower run for an older commit can edit labels after a newer run and restore stale colours or descriptions.
Add workflow-level concurrency so the newest synchronisation run wins.

Pull Request Overview
While this PR successfully implements a canonical label taxonomy and triage automation without external dependencies, it contains a critical logic error in the JQ classifier's regex escaping function. Specifically, the reesc function uses invalid interpolation syntax, which will cause the classifier to fail for any keywords containing symbols or punctuation (e.g., 'ci/cd' or bracketed tags).
Furthermore, although the automation logic is complex, no test files were included in this PR to verify the classifier's behavior. Codacy analysis indicates the PR is up to standards, but the implementation of the label-sync workflow is inefficient for larger label sets and sensitive to character encoding in label descriptions. These issues should be addressed before merging to ensure the automation is reliable and maintainable.
About this PR
- The PR contains zero test files to verify the logic in the JQ classifier. While external tests may exist, this repository requires local validation for its specific classification rules to prevent regressions.
Test suggestions
- Issue with recognized conventional-commit prefix (e.g., 'feat:') is classified with the correct 'type' label.
- Issue with bracketed tag (e.g., '[p0]') is correctly classified with the corresponding priority label.
- Classifier handles inflections correctly (e.g., 'tests' vs 'test') without triggering false positives (e.g., 'lean' in 'clean').
- Classifier returns empty result when the issue already has a label in the suggested label's tier (preventing human override).
- The label sync workflow correctly creates missing labels and updates colors/descriptions of existing ones.
- Labels in the 'frozen' list are ignored by the sync workflow to prevent breaking external automation.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Issue with recognized conventional-commit prefix (e.g., 'feat:') is classified with the correct 'type' label.
2. Issue with bracketed tag (e.g., '[p0]') is correctly classified with the corresponding priority label.
3. Classifier handles inflections correctly (e.g., 'tests' vs 'test') without triggering false positives (e.g., 'lean' in 'clean').
4. Classifier returns empty result when the issue already has a label in the suggested label's tier (preventing human override).
5. The label sync workflow correctly creates missing labels and updates colors/descriptions of existing ones.
6. Labels in the 'frozen' list are ignored by the sync workflow to prevent breaking external automation.
Low confidence findings
- The triage workflow relies on fetching file contents via the GitHub API at specific SHAs to avoid a full checkout. This makes the system dependent on API response formats and specific permission scopes remaining static.
- The 'No uses:' constraint has resulted in significant shell boilerplate for API interactions (base64 decoding and manual loops). This increases the maintenance surface and fragility of the automation compared to standard GitHub Actions.

🔴 HIGH RISK
The reesc function incorrectly uses JQ interpolation \(.c) to reference a regex capture group. In jq, gsub replacement strings use & for the whole match or \1 for numbered groups. As written, this will replace special characters with the literal string 'null', breaking the regex for any keyword containing punctuation (e.g., 'ci/cd', '[p0]').

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.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win
Re-check labels before applying the result.
HAVE is read at Line 82 before classification and before gh issue edit. If a human adds a max-1 label during this interval, the classifier uses stale state and adds a second label in that tier. This breaks the stated rule that the classifier stays out of a tier already classified by a human.
Re-read the labels and re-run classification immediately before the edit. Serialise triage runs per issue. Use a conditional update if this invariant must be strict.
