An artifact, or draft, is a single reviewable email in the Workbench, stored as a structured block document with stable block IDs. Block-level annotations and supported direct edits are live; document-level chat re-drafting remains design-only.
For example, pin an instruction to one paragraph. If the patch passes its checks, Deloosh creates a new document version without replacing unrelated blocks.
