The big win?.AI doesn't just write the story โ€” it calls Java functions to alter game state. LLMs are finally doing things, not just saying them.

Had to upgrade to Spring AI 1.1.0-SNAPSHOT due to function call exceptions. โœ… That fixed it. โœ… Function calls are now routed cleanly to Ollama (LLaMA 3.2).
