billing_adapter.rs

//! The single permitted gkg-server↔gkg-billing seam.
//!
//! Billing logic lives in `crates/gkg-billing/`. The only data that crosses
//! the boundary is `BillingInputs` (defined there). This file is the
//! complete declaration of which `auth::Claims` fields populate that struct.
//! All billing-related call sites in gkg-server consume `BillingInputs`
//! built via this `From` impl — they never construct `BillingInputs`
//! directly. Per SOX boundary policy, this file plus the `gkg-billing`
//! crate are the entire auditable surface for billing in this repository.
