- The split screen is a system, not a mode welded into one game — a new question set is added in lib/versus.ts and nowhere else
- Eight question sets across all four Squares, every one cut from a bank the repo already had — only the arithmetic is generated
- Every wrong option is a real answer to another question — nothing invented, which would be eliminated on sound alone
- 12,800 questions brute-checked by verify:versus — no question has two right answers, and none repeats inside a round
- The round does not end when the first player finishes: their half locks and the other plays on
- Two honours, finished-first and most-right, and the word for losing appears nowhere
- Three wrong in a row offers that half a breath — and the other player never has to know
- Still a gradient: this game has no painted stage of its own yetplanned
- Two players still sit shoulder to shoulder; the across-the-table layout is not builtplanned
✓ = done · ☐ = planned. Every game is built one step at a time like this.
