Collaborative Document Workspace

A shared workspace where multiple authors concurrently draft, comment, redline, and version a single document in place. Presence, suggestion mode, and thread-level comments replace the email-and-attachment loop — the workspace is the artefact, live and singular.

Mechanism

Provides a shared document / space where multiple authors concurrently co-author, comment, redline, and version a single artefact in place — the workspace itself IS the artefact-in-progress.

Why this is a primitive

Cannot be decomposed — the operation is one act of being-a-multi-author-document-workspace: concurrent edit, presence, comment, redline, version history, on a single shared artefact. Strip the multi-author concurrency and you have a single-author editor (no primitive). Strip the document-as-shared-artefact and you have a chat tool. The combination — many authors on one document-shaped artefact — is irreducible. Note: this primitive sits at the share-it / act-on-it-together seam. Routes to share-it because the load-bearing operation is authoring-an-artefact-together (the artefact is the transmission), not coordinating multi-party WORK on shared state (no per-instance lifecycle, no routing, no gating). When the workspace is wrapped with approvals / state machines / cross-org checklists, it composes with act-on-it-together primitives (see deal-room composition).
