+"""Issue #1160 — a closed document must not stay 'active' and leak into new chats.
+
+Closing a document tab detaches it (session_id -> NULL) or deletes it, but the
+in-memory active-document pointer was never cleared, so the last-resort doc
+injection re-surfaced the closed doc in later, unrelated chats. The document
+routes now call clear_active_document() on detach/delete; this pins that helper.
