# cancel-in-progress is DELIBERATELY false: CodeQL is a REQUIRED
# code-scanning tool in the estate branch rulesets (a result must upload
# for the head commit before a PR can merge). A cancelled run uploads
# nothing, leaving branch protection stuck "expecting 1 result from CodeQL
# for <sha>" indefinitely — the ghost check that blocks PRs for hours/days.
# Queue rather than cancel so the latest commit's scan always completes and
# uploads. (Non-required read-only workflows may still cancel-in-progress.)

# `startup_failure` with zero jobs. security-events: write is what uploads
