wall_collision Oracle False Positive — pacY=$00 Is The In-Maze Top Row

Game: Pac-Man (NA) Goal: G-A2600-001 (Pac-Man wall collision correctness) Concern: the wall_collision oracle in phase2/console_loop.py was failing on every 1800-frame Pac-Man run with pacY=$00 = off-maze top boundary. Iter 1 (Finding 25) added Y-write telemetry on the assumption that the writer at $FA23 was bypassing a missing maze-top guard.
