260-295: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winMake the classifier independent of object key order.
sameValuecompares byJSON.stringify, so it is sensitive to property order.actualkeeps the key order produced by the live query result at Line 244.expectedkeeps the literal order fromrecomputeRowsat Lines 226-236. Both agree today only because the Q1selectat Lines 123-147 lists the keys in the same order. If the query engine changes the emitted key order, the classifier returnsfalse,expectDroppedQ2FailureAtrethrows, and the suite reports an unclassified failure instead of the intended#1713classification.Compare structurally instead.

Summary
Adds a layered-query oracle for the publication bug in #1713. The driver compares Q1 and a Q2 built from Q1 against an independent recomputation after each controlled source change.
The expected-failure classifier is narrow: Q1 must be exactly correct, while Q2 must be exactly correct except that both sibling
materialize()fields arenull.Coverage
where,orderBy, andselectpipelinesThis catalogs the existing #1713 publication defect; it did not find a separate bug class.
