737-1738: 💤 Low valueComprehensive and accurate documentation of the reframed fix.
The implementation note correctly identifies that the original proposed optimization (
newSubRows !== row.subRowscheck) was flawed and explains the actual solution: unconditional recursion to collect selected descendants, cloning only selected parents, and prototype preservation viaObject.create+Object.assign. The bug fix (spread syntax dropping the prototype chain) is well-documented and matches the pattern established in finding#49. Regression test additions are confirmed by the relevant code snippets.Minor clarity suggestion: Line 738 mentions "The per-iteration row binding is also changed to const for immutability." The word "changed" suggests a transition from
lettoconst, but the note doesn't show the before-state. If this was alreadyconstin the original code, consider rephrasing to "uses const" to describe the final state rather than implying a change. If it genuinely was changed fromlet, this is fine as-is.🤖 Prompt for AI Agents
Verify each finding against current code. Fix only still-valid issues, skip the rest with a brief reason, keep changes minimal, and validate. In `@perf.md` around lines 737 - 1738, The documentation's implementation note states "The per-iteration row binding is also changed to const for immutability." — update that sentence for clarity to either "uses const for per-iteration row binding" if the final code already used const, or explicitly state "changed from let to const for per-iteration row binding" if you did perform the change; reference the sentence in the implementation note describing the reframed fix (the paragraph explaining unconditional recursion, cloning only selected parents, and prototype-preserving Object.create/Object.assign) so readers know whether the wording describes the final state or an actual transformation.
