/**
 * VialOS × Circle — Live Demo Script (Honest Edition)
 *
 * Every number is real. Every tx hash is verifiable.
 * No fake animations. No pre-set results.
 *
 * Usage:
 *   npx tsx --env-file=.env circle-live-demo.ts
 *
 * What this does (live, in order):
 *   1. Query Gene Registry → show real capsule count + top errors
 *   2. Show real Exp A result: 5/5 LLMs trapped (from JSON)
 *   3. Send one live tx on Arc testnet (decimals repair)
 *   4. Show real Exp B result: 60%→100% rate limit (from JSON)
 *   5. Show real Exp C result: 537ms registry inheritance (from JSON)
 *   6. Show real Exp D result: 36%→96% 10-hop workflow (from JSON)
 *   7. Open arcscan.app to verify tx hashes
