Check loader and version before Groq or Ollama
A Java mod can fail before the AI layer ever runs. If you place a Forge file into a NeoForge profile, use a 1.20.1 jar in a 1.21.1 profile, or add old dependencies from a video, Minecraft may crash or skip the mod. The first diagnosis should always be edition, version, loader, and dependency. Only after the game launches cleanly should you debug Groq, Ollama, voice, or the behavior of the Verity entity.
Build a clean test profile. Install the matching loader. Run the profile once. Add only the required Verity JE file and documented dependencies. Launch again. If that works, create a test world and confirm the basic mod behavior. After that, configure AI or voice. This order prevents a provider error from looking like a broken download.
