+# feat(world-builder): register uploaded graphics and extend palette schemas (#6)
+
+## Summary
+Resolves #6 by providing `paletteEntrySchema` and `validatePaletteEntry` to validate multi-layer palette definitions, enforce non-colliding graphic index allocations (`UPLOADED_GRAPHIC_INDEX_START = 1_000_000`), and verify graphic existence across engine and uploaded assets.
+
+### Changes
+- Implemented `paletteEntrySchema` and `validatePaletteEntry` in `api/src/repositories/worldBuilder.ts`.
+- Added unit tests in `api/src/repositories/__tests__/paletteValidation.test.ts`.
+
+Closes #6
