 ### Phase 7 — Finalisation (later)
 
+- [ ] 7.0 Open items carried over from Phase 6 (none blocks 7.1):
+  - Q2 board asymmetry (deferred by the developer).
+  - 6.4.1 chance square (parked, D49).
+  - Heuristic bots draw a Nebbia card on only 2.3% of turns (6.6): card effects are measured mostly through the casual bot.
+  - Remaining small bot tie-breaks by absolute board order (Tunnel destination; the engine keeps the first path per outcome): corner residual 24.0–25.4% after D51.
+  - At 6 players the two seats alone in a Safe Room win 17–20% vs 13–17% for the four sharing (6.2.3); accepted with D52.
 - [ ] 7.1 Freeze rules.
 - [ ] 7.2 Italian edition.
 - [ ] 7.3 Physical tracking method and components; printable board.
