# Smoke test for a running mana-geocoding service.
#
# Runs a handful of real-world queries against the wrapper and asserts
# that each returns at least one result with sensible category mapping.
# Fails fast on the first unexpected response.
#
# Usage:
#   ./scripts/smoke-test.sh                         # default http://localhost:3018
#   ./scripts/smoke-test.sh http://mana-geocoding:3018
#   BASE=http://mana-geocoding:3018 ./scripts/smoke-test.sh
#
# This is NOT a substitute for the unit tests in src/lib/__tests__/ — it
# requires a fully deployed Pelias stack with the DACH index already
# loaded. It's the test to run after a deploy to confirm the full pipeline
# is healthy.
