    Build and operate Arbol's organization-scoped conversational platform
    through one provider-neutral REST contract. Resources cover Agents,
    channels, contacts, conversations, Knowledge, connected accounts, analytics,
    and evaluation runs. Every bearer is verified by Auth0, every request is
    bound to exactly one Organization, and every operation enforces all scopes
    listed in its security requirement.
