- the graph binary is NOT committed: routing/data/.gitignore ignores *.bin (git check-ignore verified) — forks rebuild their own (docs/ROAD-GRAPH.md), so the old assertion message was factually false - CPU3 now mirrors CPU4's law: absent binary -> honest SKIP (not a failure); the run-the-ladder assertions fire only when it is present - reason text aligned with reality: 'gitignored fork-rebuildable artifact'
