feat(labels): estate label tooling + auto-triage for new issues - #58

📝 WalkthroughSummary by CodeRabbit
WalkthroughAdds a label taxonomy, a jq-based issue classifier, and two GitHub Actions workflows. The workflows classify opened or reopened issues and synchronise repository labels while preserving frozen labels. ChangesGitHub label automation
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds automated label synchronization and issue triage. Current workflows may silently succeed after payload-read failures, bypass frozen-label protections when state is malformed, fail during concurrent synchronization, or apply stale classifications that create conflicting labels. These are bounded risks requiring owner awareness or follow-up, but the supplied evidence does not indicate a high-impact or release-blocking issue. Sequence Diagram(s)sequenceDiagram

Pull Request Overview
While the PR is technically 'up to standards' according to automated quality gates, there are several significant issues that should be addressed before merging. Most notably, the PR description claims to update .github/workflows/actions.lock, but this file is missing from the commit.
A logic bug in the JQ-based classifier results in incorrect keyword matching (e.g., 'theoryies'), and the label sync workflow contains inefficient shell loops that will impact performance as the taxonomy grows. Furthermore, the complex classification logic is currently unverified by any unit tests, posing a high risk for regressions in issue triage.
About this PR
- The complex JQ-based classification logic lacks unit tests. Given the risk of incorrect issue categorization, automated tests should be added to verify regex patterns and inflection rules.
- There is a discrepancy between the PR description and the files changed:
.github/workflows/actions.lockwas not found in this PR despite being mentioned as updated.
Test suggestions
- Verify an issue title with a 'feat:' prefix correctly applies the 'enhancement' label.
- Verify a bracket tag like '[p1]' correctly applies the 'priority:p1' label.
- Verify keywords such as 'broken' or 'crash' in the title correctly apply the 'bug' label.
- Confirm that existing labels on an issue prevent the classifier from adding a second label of the same tier (e.g., prevent adding 'enhancement' if 'bug' is already present).
- Ensure 'frozen' labels (e.g., dependencies, security) are not modified or updated by the label sync workflow.
- Check that the label sync workflow correctly updates the color and description for non-frozen labels when drift is detected.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify an issue title with a 'feat:' prefix correctly applies the 'enhancement' label.
2. Verify a bracket tag like '[p1]' correctly applies the 'priority:p1' label.
3. Verify keywords such as 'broken' or 'crash' in the title correctly apply the 'bug' label.
4. Confirm that existing labels on an issue prevent the classifier from adding a second label of the same tier (e.g., prevent adding 'enhancement' if 'bug' is already present).
5. Ensure 'frozen' labels (e.g., dependencies, security) are not modified or updated by the label sync workflow.
6. Check that the label sync workflow correctly updates the color and description for non-frozen labels when drift is detected.
Low confidence findings
- Fetching the classification script via
gh apiusing$GITHUB_SHAintroduces a runtime dependency on the GitHub API. While this supports portability, ensure the workflow handles API rate limits or transient failures gracefully.

🟡 MEDIUM RISK
Suggestion: The nested loop with awk and printf is inefficient. Refactor the sync job to use a Bash associative array to store and look up existing label metadata, eliminating the need to fork processes inside the loop.

⚪ LOW RISK
The inflection logic for keywords ending in 'y' results in incorrect plural matching (e.g., 'theoryies' instead of 'theories'). Consider stemming keywords in the JSON or updating the logic to correctly transform 'y' to 'ies'.

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.

Refresh HAVE immediately before applying labels.
If a maintainer adds enhancement after the current read, classify-issue.jq can emit bug from the stale snapshot. The additive gh issue edit --add-label call can then leave both labels in the type tier. Re-read labels and re-run classification or filter apply against the latest snapshot. This narrows the race but does not make the update atomic.

GitHub Actions official documentation concurrency group runs concurrently cancel-in-progress false
💡 Result:
In GitHub Actions, setting cancel-in-progress: false does not mean that all subsequent workflow runs will be queued; instead, it specifically dictates how the system handles a running job when a new one is triggered [1][2][3]. Here is how the system behaves when cancel-in-progress: false (the default) is configured for a concurrency group: 1. Running Jobs are Protected: If a job or workflow is currently in progress within the defined concurrency group, it will be allowed to complete its execution [1][2][3]. It will not be interrupted or canceled by newer runs [1][3]. 2. Queue Management: By default, GitHub Actions maintains a capacity of at most one running job and one pending (queued) job per concurrency group [4][5][3]. 3. Eviction of Queued Runs: If a new run is triggered while one job is already running and another is already in the "pending" (queued) state, the existing pending run is canceled, and the newest run takes its place in the queue [1][3]. Consequently, cancel-in-progress: false only ensures that the running job is not canceled; it does not prevent the "last-in-wins" behavior for queued jobs [1][3]. To allow more than one job to wait in line, you can now use queue: max in your concurrency configuration [4][5]. When queue: max is enabled, GitHub Actions allows up to 100 jobs to be queued sequentially within the concurrency group, rather than canceling older pending runs [4][5]. Note that queue: max cannot be used in combination with cancel-in-progress: true [6][7].

Serialise label synchronisation runs.
Concurrent runs can read the same missing-label state. One gh label create call can then fail with an already-exists error, and the affected run exits with status 1 when no other mutation succeeds.
Add a workflow concurrency group with cancel-in-progress: false.

Fail when the canonical payload cannot be read.
.github/labels.json is present and contains the canonical label set. Line 52 masks gh api and Base64 decoding failures. Line 53 then treats an empty payload as a successful no-op. An API failure can therefore report a successful sync without making changes.
Capture the read result separately. Fail for API or decode errors. Keep the successful no-op path only for an explicitly supported missing-file response.

Validate frozen before label mutations.
If .frozen is missing or has the wrong shape, jq can fail inside process substitution while mapfile still populates an empty FROZEN array. The mutation loop can then edit frozen labels. Validate that .frozen is an array of strings and that .labels is an array before populating FROZEN.
