  title: Questra Program API
  version: 0.0.1
  description: >-
    REST API for the Questra Program product. Browser users authenticate through
    Questra Auth SSO; automation uses workspace-scoped API keys (`Authorization:
    Bearer qpk_live_…`). API keys carry scopes enforced before handlers.
    Outbound webhooks follow Standard Webhooks (at-least-once delivery;
    consumers must be idempotent).
