# ELIDA Demo Script
# Demonstrates security features with simulated multi-user traffic
#
# Usage:
#   ./scripts/demo.sh                    # Full demo
#   ./scripts/demo.sh --quick            # Quick demo (fewer requests)
#   ./scripts/demo.sh --attack-only      # Only run attack scenarios
#
# Prerequisites:
#   - ELIDA running on localhost:8080 (proxy) and localhost:9090 (control)
#   - A backend LLM or mock server
#
# To start ELIDA with policy + capture-all enabled:
#   ELIDA_POLICY_ENABLED=true ELIDA_POLICY_PRESET=standard ELIDA_STORAGE_ENABLED=true ELIDA_STORAGE_CAPTURE_MODE=all make run
#
# Or use the mock backend:
#   ./scripts/demo.sh --with-mock
