Tip For best results, initiate chat on the files or code changes.
The duplicate legacy map sources are removed. The unified terrain path now validates finite coordinates and a finite, positive radius before integer conversion. This resolves the reported ARM64 and x86_64 determinism risk. The Conventional Commit warning does not apply to unchanged upstream commit ✏️ Learnings added
