Out of scope

  • Frank.GameEngine.Rendering.* (per gameengine-reference-policy.md)
  • Classic 2.5D raycaster, WAD loader, multiplayer, audio bindings
  • GameObject, Scene, Scene2D, Sprite2D engine graph

Dependencies

  • Novolis.Math.Geometry → Novolis.Math.Arrays (for DenseGrid<byte> in collision)
  • Dogfood app → Novolis.Raylib, Novolis.Math.Arrays, Novolis.Math.Geometry
  • Phase 2: Novolis.Physics + math arrays

Assets

  • Kenney Tiny Dungeon (CC0) — vendored subset under apps/DoomLite3D/Assets/ with CREDITS.md
  • No id Software Doom/Wolfenstein art

Done when

  • dotnet build / dotnet run --project apps/DoomLite3D from novolis-dogfooding
  • New math APIs have TUnit tests
  • Raylib billboards/plane in generated World + RayGameContext
  • CREDITS.md lists every external file and source URL
