# Interface CapabilityInvocationResult

The blocking-RPC result the caller receives, host-validated.

```typescript
interface CapabilityInvocationResult {
    channel: CapabilityResultChannel;
    envelope?: CapabilityResultEnvelope;
    error?: string;
    errorCode?:
        | "outcome-unknown"
        | "cancelled"
        | "interrupted"
        | "schema-invalid"
        | "denied"
        | "no-descriptor"
        | "egress-blocked"
        | "worker-mismatch"
        | "worker-error"
        | "idempotency-conflict"
        | "integrity-failed"
        | "outside-reviewed-eligibility"
        | "apply-failed"
        | "consent-pending"
        | "consent-expired"
        | "policy-blocked"
        | "precondition-unmet";
    invocationId: string;
    ok: boolean;
    resourceArtifacts?: {
        byteLength: number;
        digest: string;
        kind: "files"
