Users (end-users)
Portal identities for people at customer companies.
Users in the team nav are end-users (portal people), not staff members.
Staff members are managed under Settings → Members.
What an end-user record holds
- Display name and email
- Parent company (Acme)
- Host
externalId - Optional attributes used by restricted visibility (e.g.
plan=enterprise)

How they get into the product
- Host SaaS upserts the end-user (or they are created when a ticket is filed on their behalf).
- Host mints a MagicLink for that end-user.
- They land on the customer portal for a single session.
They never set a SolutionDesk password.
