[watsonx troubleshooting guides]: 'Model ID not found' means the model is deprecated or unavailable in your region or plan: list live model IDs with get_model_specs and check the model lifecycle before pinning an ID. Truncated generate_text output means max_new_tokens is too low or a stop sequence fired: raise max_new_tokens and inspect the raw generate results. For 429 throttling on bulk calls, lower the concurrency limit and batch with backoff instead of retrying hot.

Context: Model ID errors and truncated generations have one-line fixes each.
