Findings

• Public type contract drift still exists across the node-transform family, not just setNodes: legacy Transforms.* and editor.* methods were generic over T extends Node, while current v2 still narrows most of them to non-generic option bags and instance signatures.
• packages/slate/src/transforms-node/* same-path files are still rewrite-heavy rather than source-close legacy ports. That is not automatically wrong, but it means the family is not "recovered" in source terms.
• The strongest proven gap was setNodes<T> and it is now fixed. The same failure mode still appears likely for insertNodes, liftNodes, mergeNodes, moveNodes, removeNodes, splitNodes, unsetNodes, unwrapNodes, and wrapNodes.
• Current docs/ledgers already admit partial transform-family closure rather than full same-path parity, especially for broader path/match/selection/void lanes.
