# Local-only stack for the Doormile AI retrieval sidecar.
#
# This is DEV TOOLING. The production image is still the static nginx build in
# Dockerfile — nothing here is deployed, and the console works with this stack
# absent (the bot falls back to its deterministic matcher when REACT_APP_AI_URL
# is unset or unreachable).
#
#   docker compose up -d          start Chroma + the sidecar
#   npm --prefix services/ai run seed    build the collections
