AgentOven Integration Test — Customer Support Ticket Triage Pipeline
=====================================================================

Real-world scenario:
  A SaaS company (BrightBud) uses AgentOven to build an automated support
  ticket triage system. The pipeline has three agents:

  1. "triage-classifier"   — reads a ticket, classifies severity & category
  2. "knowledge-retriever" — searches the company knowledge base (RAG) for
                             relevant articles before escalating
  3. "response-drafter"    — drafts an initial customer response

  These agents are wired into a recipe ("support-triage-pipeline") with a
  DAG: classifier → retriever → drafter, plus a human gate after the drafter
  so a support lead can approve before sending.

What this test exercises (NO embedding drivers — pure HTTP API):
  • Agent CRUD (register, list, get, update, bake, delete)
  • Recipe CRUD (create, get, list, bake/run, history, delete)
  • RAG Ingest  (POST /api/v1/rag/ingest — push docs into the pipeline)
  • RAG Query   (POST /api/v1/rag/query  — semantic retrieval)
  • Recipe Run lifecycle (submitted → check status → history)
  • Cross-entity references (recipe steps referencing agents)
  • Cleanup (delete everything at the end)

Prerequisites:
  - Control plane running at http://localhost:8080
  - In-memory store (default — no PG needed)

Run:
    cd ent-agent-core
    python3 sdk/python/tests/test_agent_recipe_rag.py
