# Supervisor image build.
#
# The final image carries the static `openshell-sandbox` binary used by Docker
# extraction, Podman image volumes, and Kubernetes side-loading. It also carries
# a materialized helper runtime used for trusted network setup and enforcement.
#
# The Rust binary is built natively before this image build runs and staged at:
# deploy/docker/.build/prebuilt-binaries/<arch>/openshell-sandbox
#
# Use tasks/scripts/docker-build-image.sh supervisor (or `mise run build:docker:supervisor`)
# to stage the binary and build the image in one step. CI builds the binary
# per-architecture via the `rust-native-build.yml` workflow (with the musl
# target) and uploads it as an artifact, which is downloaded into the same
# staging directory before the image build job runs.
