+- **Quaternius bake keeps source detail (2026-11-05, owner):** during the contract bake (§2),
+  keep the Quaternius mesh as close to source as possible — no unnecessary decimation or LOD

+  there is no budget reason to decimate before the silhouette gate. Do not reuse the old
+  7,000-triangle or MPFB decimation targets.
