Code Review

correctness: 2/4edge case handling: 2/4introduced bug risk: 2/4maintainability idioms: 3/4

The patch is directionally correct and likely fixes several failing cases, but it does not fully match the intended rewrite semantics; key correctness gaps remain in union rewrite gating and recursive fragment flattening behavior.

3 findings

Union-only inline fragments can skip rewrite due to existing early-return flow

major

The union cleanup check was added, but it sits after the pre-existing flow where union rewrite decisions may return before evaluating union fragments when no interface fragments are present. This can miss required rewrites for selections that rely on union nested fragments.

v2/pkg/engine/plan/abstract_selection_rewriter.go:177

Union flattening still copies object fragment selections instead of recursively normalizing them

major

In `flattenFragmentOnUnion`, object inline fragments are copied directly (`CopySelection`) rather than recursively flattened through nested abstract fragments. This can preserve invalid nested structure instead of rewriting to concrete-type fragments.

v2/pkg/engine/plan/abstract_selection_rewriter.go:472

Top-level object-fragment cleanup path still may not enforce parent-valid-type membership

major

The helper now supports parent-valid-type checks, but the main interface/union rewrite decision flow was not fully switched to the new object cleanup strategy, leaving paths that still rely on datasource existence checks and can miss parent-membership filtering.
