# Platform Billing Defaults

Owner-level billing configuration. Loaded from KV at key `billing:_platform`; seeded
at deploy time. Plans, models, and metered rates are defined as the TypeScript constant
`PLATFORM_BILLING_CONFIG` in `src/lib/billing-config.ts` and are the authoritative source.

Mutate via the `/_platform/billing` owner dashboard (O2). After mutation the KV key is
invalidated and reseeded from the updated constant + any owner overrides.
