     // R-R (docs/cultnet-selection-cut.md, Self's rulings 2026-09-22) corrects the earlier commit-2
     // ruling this test used to pin: an explicit empty recordKeys array is a real filter, not "no
-    // filter". ResolveDefaultSelection must not fall back to the type's own schema default just
-    // because the caller's recordKeys happened to be empty - the wire must carry recordKeys=[] and
-    // no schema default, and the answer is empty, exactly as v0 answered before this cut
-    // (CultNetDatabase.CreateShardSnapshotResponse at b3d9cf7 tests RecordKeys != null, not a length).

+    // reported rather than silently resolved: at CultMesh's typed convenience layer this selection
+    // never reaches the wire at all. ResolveDefaultSelection now produces Keys=[] instead of Keys=null,
+    // and EnsureV0Compatible - CultMesh's own client-side door, landed under the earlier ruling R-F -
+    // already refuses an empty selection.keys before any request is sent ("Keys=[]/[\"\"] is refused
+    // rather than silently lowered to 'every key'", CultMeshSnapshots.cs:836-841). R-R's "recordKeys:
+    // [] answers empty" therefore only holds for the raw v0 wire protocol server, which any v0 peer
+    // can call directly without CultMesh's typed wrapper - see
+    // CultNetDocumentRegistry_RawSnapshot_ExplicitEmptyRecordKeys_AnswersEmpty in NetworkingTests.cs.
