# EP-00-T04 (walking skeleton) + EP-16-T01 (grows into the full stack).
#
# `core` profile = M0: gateway + one example MCP server, static routing, no
# enforcement yet. Later milestones add services under additional profiles
# (`identity`, `policy`, `observability`, `llm-observability`, ...) so `docker
# compose --profile core up` stays cheap through M0/M1 instead of requiring
# the whole stack (Keycloak, OPA, Langfuse, ...) just to see the walking
# skeleton trace.
#
# NOT executed against a real Docker daemon in the session this was authored
# in (no `docker` binary in that sandbox) -- validated instead by running the
# same two processes directly on the host (see RI/README.md). Please run
# `docker compose --profile core up --build` on first use and report back if
# anything needs adjusting.
