+// Document source trees keep ONE physical `mem_tree_trees` row per
+// connection (e.g. `notion:{connection_id}`), but inside it each document
+// rolls up to its own **doc-root** summary, and those doc-roots merge into
+// the connection root. To get that shape without re-keying the shared
+// `(tree, level)` buffer — the exact path chat/email seal through — the
+// per-document subtree is built as an **isolated side-cascade**
+// ([`seal_document_subtree`]) that never touches a shared buffer or the
+// tree root. Only the cross-document **merge tier** uses the shared buffer
+// + the existing [`cascade_all_from`] engine, starting at
+// [`MERGE_LEVEL_BASE`].
+//
+// Versioning is forward-only: editing a Notion page calls
+// [`seal_document_subtree`] again with a higher `version_ms`, producing a
+// *new* doc-root that is appended to the merge buffer alongside the old
+// one. Nothing is rewritten or tombstoned; retrieval keeps `max(version_ms)`
+// per `doc_id` at read time (see the retrieval layer).
+
+/// Level offset where the cross-document merge tier lives inside a document
+/// source tree.
+///
+/// Per-document subtrees occupy small levels (1, 2, …) and are built by
+/// [`seal_document_subtree`] as a side-cascade that never enters a shared
+/// `(tree, level)` buffer. The merge tier — which summarises *across*
+/// documents — uses the shared buffer and the existing cascade engine,
+/// starting here. The wide gap guarantees per-doc nodes (small levels) and
+/// merge nodes (≥ `MERGE_LEVEL_BASE`) can never collide on `(tree, level)`,

+///    leaves. Every node is tagged `(doc_id, version_ms)`.
+/// 2. Append the doc-root to the connection tree's merge buffer at
+///    [`MERGE_LEVEL_BASE`] and run the existing cascade so it folds into the
