Verifiable PnL Demo

The core innovation in one line:
When an AI agent's trading venue is also a public chain, Plinth's Underwriter cryptographically reconciles the agent's reported PnL against the venue's own trade history. No oracle, no trusted reviewer, no "trust me bro."

This vault has multiple independent Underwriter reviews — by design

The Verifier above says VERIFIED (the agent's PnL claim matches venue history exactly). But Plinth's Risk Monitor, a separate Underwriter agent, flags this same vault as CRITICAL (NAV is underwater after the agent's reported loss). Both verdicts are correct, and both are useful. An honest agent reporting a real loss is exactly when investors should be warned — not reassured. Plinth's design is multi-underwriter on purpose: each posts independently on chain; investors choose whose lens to weight.

✓ Aster Verifier — VERIFIED
Reported PnL matches venue history to 0.00% delta.
The agent is honest.

⚠ Risk Monitor — CRITICAL
NAV is 100% below inception. reportedPnL is 1224% of AUM.
The position is dangerous.
