# Members DocumentParameter client

The generated `document_parameters` client exposes the governed
`GET /documentparameters`, `POST /documentparameters`, and
`PUT /documentparameters` operations.

Every call requires the caller to provide both the server-held API-key
authentication writer and the native `kvSession` cookie through the request
transport. The Members service enforces the exact
`members:document-parameter:read`, `:create`, or `:update` machine scope.
Active Contributors can read only their own records. Creates and
compare-and-swap updates require tenant Owner or Manager authority.

`DocumentID` is required and validated against the same tenant.
`LastModifiedDate` is the optimistic concurrency token; stale updates return
409. IDs, tenant ownership, and audit fields remain server-owned.
`IsDeleted` and `DeletedDate` are lifecycle-owned, and the client exposes no
generic delete operation.

Folder client generation is deferred because the authoritative Folder schema
contains `AccountID` and a polymorphic `ObjectID`/`ObjectType` pair without
governed same-tenant reference metadata. Publishing those writes would be less
safe than the unambiguous DocumentParameter-to-Document relationship.
