+"""Associate documents with the knowledge space they were ingested into.
+
+No production row exists yet (ingestion was never wired to a worker handler
+until this change), so this adds the column as NOT NULL directly rather than
+nullable-then-backfill-then-constrain: there is nothing to backfill.
+
+Deliberately no FK to control.spaces: content.documents.workspace_id already
+has no FK to control.workspaces (control and content are separate bounded
+contexts in this schema, and cross-schema FKs have no other precedent in
+this codebase), so space_id follows the same established convention --
+indexed, not foreign-key-enforced.
