Unity Grid Level Editor

Use unity-cli and unity-game-dev for repository readiness and tooling. Read the authoring recipe before changing draft, geometry, save, preview or solver behavior. Inspect the runtime board rules and existing authoring authority first.

Establish ownership

Choose one authored data authority per dataset. A draft, recovery record, runtime catalog and scene preview are separate owned projections, never additional editable sources. Follow the current JSON/ScriptableObject choice; do not add import/merge/export round trips without a request.

Name allowed code paths, exact writable datasets/settings and test scratch paths. Save only owned assets, never globally with AssetDatabase.SaveAssets or a vendor helper that saves all dirty assets. Asset/schema/scene/settings changes retain their target approval. Tests must leave unrelated dirty assets and production data untouched.
