Kdocs versions, buyer links, signatures, and audit history

Versions stay explicit#

Editing a document creates or advances a stored version instead of rewriting the buyer history. Review the current version and document hash before activating a share.

Private buyer links#

• A buyer link is unguessable and tied to one document.
• The link works only while the share is active.
• Revoking a share stops future access without deleting the workspace's audit history.
• A room can share a specific document version so later edits do not quietly change what that buyer received.

Signatures and exports#

A typed signature is accepted only for the active, unchanged document. Export and download actions remain scoped to authorized workspace users and are disabled during support viewing.
