| Two defects had silently disabled the LLM paraphrase, and the service looked |
| healthy the whole time because falling back to the Stage-1 template is a |
| correct, safe outcome -- indistinguishable from success from the outside. It |
| was only caught by noticing the live response was byte-identical to the |
| template string. |
| |
| 1. the model id qwen/qwen3.6-27b had been decommissioned (Groq answers it |
| with 404 model_not_found); |
| 2. the payload sent a system-only message list, which the model rejects with |
| 400 "No user query found in messages" -- so the call would have failed |
| even with the id corrected. |
| |
| Both are verified here against the source rather than by calling Groq, so the |
| test needs no key and cannot flake on the network. |
