cat <<'EOF_SUMMARY'

Interpretation:
- If responses contain "source":"canary-container" and logs show CANARY_REQUEST, public traffic reached the container.
- If responses show unrelated JSON such as {"data":[]} and logs show no CANARY_REQUEST, the request likely did not reach the container.
- If the response is 404 but logs show CANARY_REQUEST, the proxy reached the container but the path is wrong.
