[project troubleshooting notes]: For groq.RateLimitError, wait before retrying (check current limits at console.groq.com) or temporarily switch providers. For groq.AuthenticationError, verify the key format (Groq keys start with gsk_) and grab a fresh key from console.groq.com if needed. For groq.NotFoundError: Model not found, Groq retires models, so check the live model list at console.groq.com/docs/models and update the model name in config.

Context: Three Groq API errors keep recurring in integrations: groq.RateLimitError (Rate limit exceeded), groq.AuthenticationError (Invalid API key), and groq.NotFoundError (Model not found). Each has a distinct fix, and mixing them up wastes debugging time.
