Volume magpie-model-cache was owned by root, container drops to uid 1000. Fix:
docker run --rm -v magpie-model-cache:/cache alpine chown -R 1000:1000 /cache
+ docker restart magpie-tts. After ~3 GB NGC model download, healthy on :9000.
Aligned with sibling recipes in eugr/spark-vllm-docker. Applies on next swap to each model.
First real swap gemma4 -> qwen36 succeeded in 5:30 with --moe_backend=flashinfer_cutlass.
