/**
 * Field list 2, W1 acceptance: gstack-tree-receipt proves a real gbrain stamp
 * commit (gbrain 3ffce57b27, "v0.60.270.0 chore(release): restamp onto master
 * v0.60.269.0", 14 one-line stamps) is `same-modulo-stamps` against its
 * parent under gbrain's committed .gstack/ship-policy.json (stamp_files plus
 * stamp_patterns), with negative controls: a non-stamp byte inside a stamp
 * file and a file outside stamp_files are both `changed`. Fixture:
 * test/fixtures/ship-queue/gbrain-stamp-pair.json.
