Researcher's candidate 8977d907 (patch 843fdee9), approved by Filbert in #1669 comment 29193. Built on d58c9c5cd and applied on 04155deff without fuzz; the patch's +/- lines hash the same on both bases. Row 171's one broker.mjs line (project-name-is-repo, at :2256) is the only change on a manifest path between them.
