jq-preflight.sh --expect takes a comma-separated set (validated whole, exact
major.minor membership); pr-checks.yml passes 1.6,1.7. Both small runners float
on runner-images:ubuntu-latest, so the fleet's jq is a function of pull history
(1.7 measured on PR #933 job 12347 and PR #934 job 12360, 2026-10-29).
New record ci.jq-accepted-version-set supersedes ci.jq-version-contract
(archived); docs/ci-cd.md, the script header and runner-ships-1.6 comments now
state the dated invariant. review-verdict.yml stays floor-only.
