Procedural Generation 2D

Generate semantic game data deterministically, validate it, then map it to engine resources and visuals.

Define the generation contract

1. Inspect engine version, map representation, tile size, collision and navigation rules, content catalogs, and save compatibility.
2. Define inputs: seed, generator version, catalog version, dimensions, difficulty, biome, and required landmarks.
3. Define outputs as semantic layers rather than atlas coordinates.
4. List hard invariants and soft quality goals separately.
5. Choose the simplest algorithm family that meets the topology.
