Layer 4 Agent Oracle — Palette Shift Between f=800 and f=1500

Game: Pac-Man (NA) Goal: G-A2600-001 (Pac-Man wall collision correctness) Concern: Iter 3 fired the Layer 4 sub-agent oracle (/vision-style) on the four standard PPM screenshots (f=50/400/800/1500) to independently verify Finding 26's claim that Pac-Man is at the top maze row when pacY=$00. The agent classified the build as broken (0.95 confidence) and flagged a palette-shift artifact that Finding 26 did not catch.
