# Wald-4B v2 /v1/systemone server: vLLM 0.30.0 (bf16) on the weights as a loopback-only sidecar + wald-serve-native.
#
#   docker build -t wald-serve .
#   docker run --gpus all -v /path/to/Wald-4B:/model:ro -p 8000:8000 wald-serve
#   # ready when GET http://127.0.0.1:8000/health returns {"ok": true, ...}

# The weights directory holds config, tokenizer, chat template, model.safetensors, temperature.json and serving.json
# (native v2 engine, effort, prompt format). Another policy: -e WALD_EFFORT=none (none | auto | always).
