"""
LICITRA-SENTRY Demo Swarm Simulation.

Runs 6 scenarios demonstrating the Chain of Intent pipeline:

    S1: Researcher READ             -> APPROVED
    S2: Researcher FILE_WRITE       -> REJECTED by contract
    S3: Expired token               -> REJECTED by identity
    S4: Relay injection             -> REJECTED by inspector
    S5: PII exfiltration (SSN)      -> REJECTED by inspector
    S6: Unauthorized delegation     -> REJECTED by orchestration

Requires LICITRA-MMR running at http://localhost:8000.

Usage:
    python demo_swarm.py
