+- Preserve fractional top-k replacements regardless of delta order, including left-join updates, and honor B-tree lookup fallbacks after node splits. Preserve own JSON data properties such as `__proto__` during mutation detachment and offline transaction serialization. ([#1816](https://github.com/TanStack/db/pull/1816))
+
+  Compare same-key top-k values directly instead of hashing every replacement. This preserves cyclic payloads and avoids unnecessary full-payload traversal for ordinary updates.
+
+  Cancel structurally equal mapped top-k deltas before applying replacements. Escape Date-marker-shaped user objects in new offline records while retaining read support for the original record format.
+
+  Offline storage compatibility: new records use `valueEncoding: 2`. Older clients
+  cannot decode escaped marker-shaped objects correctly, so do not mix old and
+  new clients against the same pending outbox or downgrade while new records
+  remain. New clients still read the original unversioned format. Unknown
+  encodings and corrupt records are reported through warnings and left in
+  storage, not silently discarded; recovery policy is tracked in RFC #1659.
+
+  Reject malformed escaped-object markers rather than inventing empty mutation
+  data. Avoid redundant transfer work for zero-width fractional top-k windows
+  and avoid descriptor writes for ordinary keys during draft copying.
