Authoring model

Canonical modules for new games (humans and agents), available in Java, Python, JavaScript, TypeScript, and C under the same contract (contracts/):

NeedUse
Game loopLanguage game base + bootstrap
Top-down tilesWorld + Actor + Trigger
Map as dataGameSpec world.* / spawn.* / trigger.* / state.initial
Platformer physicsBody2D + AABB solids
AssetsGameSpec image.* / audio.* / spritesheet.* / font (Java fullest)
VerifyHeadless harness, pixel assert, playtest script, audio probe

Java remains the reference implementation for edge cases. Other languages ship the agent subset first (see package READMEs under packages/).
