PLAYGROUND the real policy engine, in your browser
Set the policy, then fire spend at it. This runs the same decision logic as SpendVeto's policy engine — per-call caps, hourly budget, rate limit, approval threshold, payee allowlist, runaway auto-freeze — entirely client-side. Nothing is sent anywhere; no wallet, no install.
This is a faithful re-implementation of client/policy.js's decision order: freeze → per-call cap → payee allowlist → rate limit → hourly budget → approval threshold. In the real product the same checks run server-side at the payment gate, so an agent can't skip them. See the governance model →
