Whole-row replacement. Sending `plan_id` attaches the customer to that plan: the plan supplies the mode, overage stance, rate card, windows and markups, and when the plan carries a minted invoice container the customer's subscription gains its overage line (a minimal monthly subscription is opened when they have none). Choosing wallet mode opens the customer's wallet if they have none; credits mode opens their pot. Both open EMPTY — the policy makes the customer billable, it grants them nothing. ## OpenAPI ````yaml put /v1/ai/billing/customers/{customer_id}/policy openapi: 3.1.0 info: title: Hyperline API version: 0.0.0 servers: - url: https://api.hyperline.co - url: https://sandbox.api.hyperline.co security: [] paths: /v1/ai/billing/customers/{customer_id}/policy: put: tags: - AI > Billing summary: Configure a customer's agent billing policy description: >- Create or replace one billing scope — the default policy, or one agent's own when `agent` is passed.
