## Contract Roles

* `AgentRegistry`: service metadata, capability tags, endpoint URL, STT price, and active status.
* `AgentOrderBook`: escrowed order state machine for agent work.
* `TreasuryPolicy`: spend caps, approval thresholds, allowed tokens, allowlist, and pause state.
* `AgentSpendCardVault`: bounded SOMUSD agent spend cards.
* `SomniaPrivacyVault`: commitment-first privacy intents.
* `AgentInvoiceBook`: STT and SOMUSD invoice lifecycle.
* `AgentReputationBook`: order-backed agent scores, completions, disputes, and evidence URIs.
* `OperatorControls`: claim-code onboarding and webhook circuit-breaker controls.
* `SomniaAgentRiskOracle`: testnet risk request and callback evidence.
