- Around line 313-328: Update
test_dry_run_refuses_case_only_duplicates_before_any_api_call to assert the
duplicate-label validation error from sync.main, rather than merely asserting
SystemExit, so the test distinguishes manifest validation from an earlier
missing-credentials exit.

Thanks @wanjinhao1, the duplicate-label guard is well covered and looks good to merge once checks pass. CLA Assistant is still red; please sign the CLA on the PR :) |

Addressed the CodeRabbit finding: replaced |

Thanks @wanjinhao1. Updated with main and addressed the remaining bot findings: the tests now require the duplicate diagnostic, the suite stays stdlib-only, and non-string label names produce a validation error. The new test-only commit failed in CI with the numeric-name AttributeError; the repair commit is green. All 71 tests pass under python3 -S, independent review is clean, and bot threads are resolved. This is ready once CLA Assistant passes. OrchardSpoon g1 🌀 |

Fixes #16193
Problem
scripts/ci/sync_labels.pytracked duplicate manifest names with exact spelling (if name in seen), but GitHub label names are case-insensitively unique —fetch_existingalready lower-cases for exactly that reason. A manifest containing botharea: cloudandArea: Cloudpassedload_manifestand--dry-run, then either failed partway through (POST conflict in an empty repo) or silently applied whichever entry came last.Change
load_manifestnow normalizes names withcasefold()for duplicate detection only; the manifest spelling is still what gets sent to GitHub, and the error names the case-insensitivity explicitly.tests/test_triage_rules.py(ManifestTests): case-only duplicates are refused by the pure validator, and--dry-runfails on them before any API operation (load_manifestruns ahead of the token check, so no credentials or network are needed).Verification
python3 -m unittest discover -s tests -p test_triage_rules.py→ 70 passed (was 68; both new tests included).python3 scripts/ci/sync_labels.py --dry-runon the real manifest →0 created, 0 updated, 33 already matching(unchanged behavior for valid manifests).AI assistance: this fix was prepared with the help of an AI coding agent, reviewed and tested by the account owner.
Summary by cubic
Fixes #16193: the labels manifest now refuses case-only duplicate label names, since GitHub treats
area: cloudandArea: Cloudas the same label.load_manifestusescasefold()for duplicate detection, and requires label names to be non-empty strings, but the manifest spelling is still what gets sent to GitHub; the error message names the case-insensitivity.--dry-run, then either hit a POST conflict or silently applied whichever entry came last.--dry-runfailing before any API call, and non-string label names getting a validation error.Written for commit 46780b1. Summary will update on new commits.
