ci-flakes.yml

name: ci-flakes

# Files one `ci-flake` issue per CI check that failed and then passed on a re-run of the same
# commit, and reopens a closed one when its flake recurs (scripts/report-ci-flakes.ts). The
# three-day lookback overlaps the daily schedule on purpose: the script skips occurrences an issue
# already lists, so a missed or repeated run neither drops nor double-counts one.
