1. User sends message via Portal / API

2. FIM One (ReAct mode):
   Think: I need to query the finance DB for overdue contracts, then push to Lark.

3. Act: contract_query(status="overdue", days_past_due=">30")
   → Connector Governance: audit log, read_only check (pass)
   → MCP Server: translates to SQL
   → Client DB: SELECT * FROM contracts WHERE status='overdue' AND ...
   ← Returns 7 overdue contracts

4. Think: Found 7 overdue contracts. I'll summarize and push.

5. Act: lark_push(message="7 overdue contracts found: ...")
   → Connector Governance: audit log, write operation → confirmation gate
   → User approves via Portal
   → MCP Server: POST to Lark webhook
   ← Push successful

6. Answer: "Found 7 overdue contracts. Summary pushed to Lark group."
