Primitives

The "primitives" are the foundational domain objects that every other feature reads or writes. Most of them are tables in src/Sql/dbo/Tables/ with matching entities under src/Core/<Domain>/Entities/ and repositories under src/Core/<Domain>/Repositories/.

Primitive	Page
User — the human or service identity	user.md
Organization — multi-tenant container	organization.md
Cipher — the encrypted vault item	cipher.md
Collection & CollectionCipher — org-shared cipher buckets	collection.md
Group & GroupUser — organization permission groupings	group.md
Device — registered client device	device.md
Send — encrypted ephemeral share	send.md

These types appear in nearly every feature page; this lens captures them once so other pages can link rather than redefine.
