COMPREHENSIVE SYSTEM TEST — AI Chatbot
=======================================
Covers the 4 gaps not tested by brutal_load_test.py + accuracy_test.py:

  PHASE 1 — RAG Retrieval Quality    Tests the retrieval layer directly (not just the LLM answer).
                                      Are the RIGHT KB chunks being fetched for each query type?
  PHASE 2 — Admin API Coverage        Every admin endpoint: auth, data structure, edge cases,
                                      rate limiting, boundary inputs, error handling.
  PHASE 3 — Widget Embed Auth         Widget key validation, CORS headers, unauthorized access,
                                      origin spoofing, key reuse across DBs.
  PHASE 4 — Post-Deploy Smoke         10 critical checks in <90s. Run after EVERY deploy.

RATE LIMITS (respected automatically):
  /chat        → 20 req/min per IP  → paced at 3.5s
  /admin/*     → 10 req/min per IP  → paced at 7.0s
  /debug/*     → admin endpoint     → 7.0s
  /config,
  /health      → no limit           → no delay

TOTAL RUNTIME: ~8-10 minutes for all 4 phases.

Usage:
    pip install aiohttp
    python comprehensive_test.py [--url http://localhost:8000] [--phase all|1|2|3|4]
    python comprehensive_test.py --phase 4         # smoke test only (~60s)
