Dockerfile

# context-guru-proxy: the LLM-proxy integration and eval-containers gateway.
#
# The module uses a local `replace github.com/maximhq/bifrost/core => ../bifrost/core`,
# so the build context MUST be the PARENT directory that contains both repos:
#
#   docker build -f lab-context-engineering/Dockerfile -t context-guru-proxy .
#
# (run from .../context-engineering/). CI that builds standalone should either
# `go mod vendor` first or switch the replace to a pinned published bifrost.
#
# CGO is required (tree-sitter for the skeleton component), so the final image is
# glibc-based. It also carries a shell + curl for the eval-containers
# start/health scripts under /opt/gateway.
