| # Leaderboard slot mapping sparse layout and sentinels | |
| RE-772. Reproduce with `python3 scripts/analyze_qvm_leaderboard_layout.py`; validate with `cargo xtask test-group leaderboard-layout`. See the [machine report](qvm-leaderboard-layout.json). | |
| Recovered complete278587 and284555 using original table31236. The mapping differs from the method-stat classifier. Integer thresholds use-1 and float metric56 uses float32-1. Two record fill patterns independently verify sparse writes and untouched fields. Selector/category semantics and native publication remain open. | |
| No original executable/full VM/native world collision or rendering runs. Supplied callback/native responses and fixture domains remain explicit; complete macOS/Linux Rust/Bevy/Solari gameplay remains open. | |
