# Model-to-upstream resolution
#
# Map a stable public model ID to an existing upstream cluster and target model.
# Unmapped models and paths use the fallback backend without a body rewrite.
# Responses retain the target model unless a provider response adapter restores
# the public ID. Cluster application-provider metadata is optional for routing.
#
# Usage:
#   cargo run -p praxis-ai-proxy -- -c examples/configs/model-to-provider.yaml
