Pull Request Overview
The PR successfully implements the core label taxonomy and triage automation without external dependencies or Python, adhering to the project's strict environment policies. While the Codacy analysis is up to standards, several functional issues must be addressed before merging.
There is a discrepancy between the PR description and the provided changes: the .github/workflows/actions.lock file and the referenced tests/test-classifier-parity.py test suite are missing from the diff. Additionally, the triage logic contains shell expansion bugs that will fail on labels containing spaces, and the synchronization check is case-sensitive, which conflicts with GitHub's case-insensitive label uniqueness. Finally, the regex for issue classification currently fails to handle multiple title tags, which may lead to missed classifications.
About this PR
- The PR description references the inclusion of
tests/test-classifier-parity.pyand updates to.github/workflows/actions.lock, but these files are not present in the PR. Please ensure all intended files are staged. - The workflows fetch their own content via
gh apiand$GITHUB_SHAinstead of using standard checkout actions. While this avoids action lock issues, it introduces a hard dependency on GitHub API availability and requires the GITHUB_TOKEN to have explicit read permissions for repository content.

The changes to '.github/workflows/actions.lock' mentioned in the PR description are missing from the diff.
Test suggestions
- Verify 'prefix:' titles (e.g., fix:, feat:) map to correct 'type' and 'area' labels.
- Verify '[tag]' titles map to corresponding meta or area labels.
- Verify that an issue with an existing 'type' label is not assigned a second 'type' label by the classifier.
- Verify keyword-based area matching (e.g., 'wasm' in title adds 'bindings').
- Verify label synchronization workflow correctly updates non-frozen label descriptions/colors.
- Verify that 'frozen' labels are created if missing but not updated if they already exist.
- Verify multi-tag stripping (e.g., [scope][feat]) identifies prefixes correctly.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify 'prefix:' titles (e.g., fix:, feat:) map to correct 'type' and 'area' labels.
2. Verify '[tag]' titles map to corresponding meta or area labels.
3. Verify that an issue with an existing 'type' label is not assigned a second 'type' label by the classifier.
4. Verify keyword-based area matching (e.g., 'wasm' in title adds 'bindings').
5. Verify label synchronization workflow correctly updates non-frozen label descriptions/colors.
6. Verify that 'frozen' labels are created if missing but not updated if they already exist.
7. Verify multi-tag stripping (e.g., [scope][feat]) identifies prefixes correctly.

🟡 MEDIUM RISK
The comparison $1==n in awk is case-sensitive, but GitHub labels are case-insensitive for uniqueness. If a label exists with different casing, this check will fail to identify it, leading to redundant creation attempts and inaccurate sync reporting.
| cur=$(printf '%s\n' "$existing" | awk -F'\t' -v n="$name" '$1==n{print;exit}') | |

There was a problem hiding this comment.
🟡 MEDIUM RISK
The command substitution $(printf -- '--add-label %q ' "${apply[@]}") will fail for labels containing spaces because the shell performs word splitting on the result. For example, a label named 'priority: p0' would be split into '--add-label', 'priority:', and 'p0'.
Refactor the label application logic in the triage workflow to build an array of arguments (e.g., args+=(--add-label "$label")) and then pass that array to the gh issue edit command to ensure safe handling of spaces.

🟡 MEDIUM RISK
Suggestion: The bracket stripping logic only handles a single leading tag. If an issue title contains multiple tags, the subsequent tags will block conventional commit prefix detection. This might be a simple fix:
| (($t | capture("^[[:space:]]*(?<w>[A-Za-z][A-Za-z0-9_./-]{1,24})(?:[[:space:]]*\\([^)]*\\))?[[:space:]]*:")) // null) as $m | |
| rest: ($t | sub("^([[:space:]]*\\[[^\\]]{1,25}\\][[:space:]]*)+"; "")) } |
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
Honour status:do-not-automate before emitting labels.
When $have contains status:do-not-automate, this branch can still emit bug, area, or meta labels. The label definition states that bots and sweeps must not touch the issue. Return an empty result before the normal confidence checks.
Proposed fix
- | if ($matched | not) then []
+ | if ($have | index("status:do-not-automate")) then []

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
