Pull Request Overview
The implementation correctly establishes a canonical label taxonomy and triage system that adheres to the estate-wide Python ban by utilizing jq. The system successfully handles conventional commit prefixes and respects existing 'type' labels to prevent over-classification.
However, a high-severity logic error was identified in the triage workflow: labels containing spaces (e.g., 'good first issue') will cause the GitHub CLI command to fail due to incorrect word splitting during shell expansion. Additionally, the label synchronization logic in labels.yml uses an O(N*M) loop that will become a performance bottleneck as the label set grows across the estate. These issues should be resolved before merging to ensure the system is robust and scalable.

line 107🔴 HIGH RISK
Arguments with spaces are not correctly preserved when expanded fromprintf %qinside a subshell. This will cause theghcommand to fail for any label containing a space (e.g., 'help wanted'). Refactor the label application logic to use a Bash array for arguments instead of command substitution to ensure labels with spaces are handled correctly.
Test suggestions
- Issue title with conventional commit prefix results in appropriate label application.
- Issue already has a 'type' label; classifier must not add a second 'type' label even if title matches.
- Title containing only keyword-area matches results in no labels being applied.
- Label sync creates missing labels and updates colors/descriptions for non-frozen labels.
- Label sync skips color/description updates for labels in the 'frozen' list.

⚪ LOW RISK
Suggestion: The label synchronization loop performs a linear search using awk on the entire list of existing labels for every canonical label, resulting in O(N*M) complexity. For better scalability across the estate, refactor this to load existing labels into Bash associative arrays (e.g., exists_col and exists_desc) before iterating, or use a single JQ pass to calculate the diff.
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 classification.
status:do-not-automate is present in HAVE, but the classifier only locks its status tier. It can still return type and area labels, which Lines 112-115 then add to an issue whose canonical label says bots must not touch it. Exit before classification when this label is present.
Proposed fix
[[ -n "$HAVE" ]] || HAVE='[]'
+ if jq -e 'index("status:do-not-automate") != null' <<<"$HAVE" >/dev/null; then
+ echo "status:do-not-automate present - leaving the issue unchanged"
+ exit 0
+ fi

Serialise label mutations.
Two runs can both detect the same missing label. One run can create it while the other run records an already exists error. If the second run has no successful mutation, lines 101-103 fail the workflow although the repository has converged.
Add a repository-scoped concurrency group with cancel-in-progress: false.
