No queries: a handler that reads fails, naming what the node lacks.

The queries of api by tenant, as a node and a test alike build them: those of a TenantQueryApi, the node's, which pins the tenant as trusted code (TenantQueryApi.tenant); for any other API, a test's fake say, QueryApi.of a caller of that tenant with no owner, space, subject or attribute, the rest NodeQueryApi.trusted.
