* Add rc.sortBy custom operator Orders an array by a key computed per item, ascending, with ties keeping their input order. Keys must be all strings or all numbers so the two engines never have to invent a cross-type ordering. Co-authored-by: Cursor <cursoragent@cursor.com> * Reject non-finite rc.sortBy keys A NaN key compares false in both directions, so every pair tied and the input came back unsorted with no error. Negating a string key to attempt a descending sort produced exactly that. Co-authored-by: Cursor <cursoragent@cursor.com> * Note ascending order in the rc.sortBy summary Co-authored-by: Cursor <cursoragent@cursor.com> * Trim the rc.sortBy doc comment Co-authored-by: Cursor <cursoragent@cursor.com> * Trim the rc.sortBy stability comment Co-authored-by: Cursor <cursoragent@cursor.com> * Order rc.sortBy string keys by UTF-16 code unit Swift's < orders by Unicode scalar and treats canonically equivalent strings as equal, while JS and Kotlin order by UTF-16 code unit. The two disagree once a scalar above the surrogate range meets an astral one, so the same rule would sort differently on iOS and Android. Co-authored-by: Cursor <cursoragent@cursor.com> * Keep the rc.sortBy ordering fixtures platform-neutral The fixture files are byte-identical across the iOS and Android engines, so a description that explains the contract in terms of one host language's string comparison does not read correctly in the other repository.
