# Regression script for Task 1: business fields must survive WeCom sync.
#
# Pre-requisites:
#   - mci-server is running (default http://localhost/msg-platform)
#   - WeCom sync client is mocked or the real client returns a conversation
#     whose channelConversationId matches the one created below.
#   - The conversation API currently does NOT expose contractId/institutionId/
#     supplierId/channelCode, so after creating the conversation via API you
#     must set contract_id = 100 directly in the DB (or extend the DTO).
#   - jq and curl are installed.
