The clean model: one Organization UIID per legal entity, not per brand.
If your sub-brands sit under the same legal entity, they typically don't need separate identities. Represent them through aliases created by the organization, or through internal roles and permissions, rather than issuing a new Organization UIID for every product line.
If a sub-brand is actually a separate legal entity — a subsidiary with its own registration — it should get its own Organization UIID. This mirrors how LINKSPREED itself is structured: LINKSPREED LLC and LINKSPREED UG are two separate legal entities serving different regions, and each holds its own registered identity rather than sharing one.
Why this distinction matters in practice: an Organization UIID can apply for Verifier status, hold application registrations, and authorize AI agents. Splitting these across too many identities makes governance harder; consolidating unrelated legal entities into one identity makes accountability murkier if something goes wrong in one part of the business.
