+Public prerelease review heads can retain `origin/main` while RNM and virtualized-lists have the same prerelease version and neither is private or ignored. They are distinct from the placeholder development graph; stable publication and version-wrapper branch guards still apply. The fork-local lists dependency uses `workspace:*` in source so Changesets tracks it, and Yarn packs it as the exact public version, including its prerelease suffix. Upstream registry dependencies keep their exact React Native peer version.
