Idempotent and never destructive: a customer already on the default plan comes back `applied: false`, a customer on any OTHER arrangement is a 409 — an applied default must never overwrite a choice somebody made. 404 when no default plan is marked. A credits-mode default draws down the pot of the product that adopted its rate card; 400 when no product has adopted it, or several have, since the pot then has to be picked on the policy surface. ## OpenAPI ````yaml post /v1/agents/customers/{customer_id}/apply-default-plan 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/agents/customers/{customer_id}/apply-default-plan: post: tags: - Agents summary: Apply the default plan to a customer description: >- Puts an unpriced customer on the workspace's default plan through the ordinary policy write — mode pinning, wallet provisioning (an empty wallet is opened on demand in wallet mode) and the plan's invoice container attach all hold exactly as on the policy PUT.
