# polyrouter production image (#22, spec §13): one container serving the SPA,
# the dashboard API, and the inference proxy on one port. Multi-stage: the
# build stage compiles the workspace and prunes dev deps; the runtime stage
# preserves the monorepo layout (/app/packages/...) so the SPA dist lookup and
# the bundled Drizzle migrations resolve unchanged.
#
# Two publishable targets share ONE build stage (add-semantic-dashboard 4.1):
#   * `runtime`          — the BASELINE (default target). musl/alpine, ORT- and
#                          model-free. `docker build .` builds exactly this; the
#                          image-inspection neutrality assertion is its gate.
#   * `runtime-semantic` — the batteries-included `-semantic` variant, built with
#                          `--target runtime-semantic`. glibc base (ORT prebuilts
#                          are glibc-only), the exact-pinned onnxruntime-node, and
#                          the reference embedding model baked in at BUILD time.
# The baseline never sees the semantic stage: it is not a dependency of `runtime`,
# so a default build skips it entirely and stays byte-for-byte the previous image.

ARG ONNXRUNTIME_NODE_VERSION=1.27.0
# glibc base for the semantic variant — onnxruntime-node's prebuilt binaries do
# not run on musl (Alpine); Debian slim keeps it lean while giving glibc.
