Development record

embargo check --range flags advisory-shaped ids that the default branch already carries once a branch has merged the default branch in, though the branch's own changes add none. The merge commit itself is not the cause: mergeAdds keeps only lines the merge adds against every parent. The likely cause is the range's commit list: rev-list a..b lists every commit reachable from b and not from a, so with a base older than the merged default branch, that branch's own commits brought in by the merge are judged as the branch's.
