Pull Request Overview
This PR implements a label management and auto-triage system. While the code adheres to Codacy standards, the Intent agent identified a significant discrepancy: several files mentioned in the PR description (documentation, test suites, and action locks) are missing from the commit.
Technically, the workflows rely on shell scripts that have risks regarding case-sensitivity and argument parsing. These should be addressed to ensure the 'additive-only' and 'no-override' requirements are reliably met. Specifically, label matching is currently case-sensitive, which contradicts GitHub's case-insensitive label behavior.
About this PR
- The following files mentioned in the PR description are missing from the PR:
.github/workflows/actions.lock,docs/LABELS.adoc, andtests/test-classifier-parity.py. Please ensure all intended files are staged and committed.
Test suggestions
- Missing recommended test scenario: Classification of issue using conventional commit prefixes (e.g., 'feat: ...' -> enhancement).
- Missing recommended test scenario: Classification of issue using bracket tags (e.g., '[p0]' -> priority:p0).
- Missing recommended test scenario: Keyword-based area matching (e.g., 'implement proof obligation' -> proofs).
- Missing recommended test scenario: Verification that existing human labels prevent auto-triage from adding a second label in the same 'max-1' tier (e.g., type, priority).
- Missing recommended test scenario: Label sync creates missing labels and updates color/description for drifting existing labels.
- Missing recommended test scenario: Label sync skips labels defined in the 'frozen' list.
- Missing recommended test scenario: Classifier returns empty list (silence) when keywords match an area but no 'type' can be determined.

🟡 MEDIUM RISK
Building command arguments with printf %q inside unquoted substitution is fragile and fails if label names contain spaces. Use a Bash array to safely collect and pass the arguments.
Update the triage workflow to collect the --add-label flags into a Bash array and pass that array to the gh issue edit command.

⚪ LOW RISK
Suggestion: The label lookup is case-sensitive, while GitHub labels are case-insensitive. This can cause the script to attempt to create labels that already exist with different casing.

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
Add the missing p3 bracket rule.
priority:p3 is a canonical label, but [p3] has no mapping. A title such as [p3] feat: ... does not receive priority:p3, and the unstripped bracket can prevent prefix classification.

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win
Add a concurrency group, and scope the token to the job.
The three triggers can overlap. A push run and the monthly schedule run can each read existing before the other creates a label, so both attempt the same create, one create fails, and failed increases without any real defect. A concurrency group removes that overlap. Moving permissions to the sync job and naming the job also clears the zizmor findings on Lines 29 and 33.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
A failed payload fetch produces the silent no-op this workflow was written to prevent.
Lines 51-52 discard stderr and swallow the exit status. Line 53 then treats an empty file as "nothing to do" and exits 0. A missing file and a failed API call are indistinguishable. On the push trigger the path filter guarantees .github/labels.json exists at $GITHUB_SHA, so an empty $PAYLOAD there always means the fetch failed. The step reports success, and the failure detector at Line 101 never runs because the script has already exited.
Separate the two cases: exit 0 only on HTTP 404, and fail on any other error.
🐛 Proposed fix to separate "absent" from "fetch failed"

- gh api "repos/$GITHUB_REPOSITORY/contents/.github/labels.json?ref=$GITHUB_SHA" \
