mikkeli	0e0ff7c4b4	Add report: Valhalla arm64 verification and the driving-side trap ... Records the investigation including the dead end — a sub-region admin build succeeds silently while producing right-hand-traffic routing — since that is the part worth keeping.

mikkeli	8ee3d4cde5	Correct admin build: must use full Japan extract, not a sub-region ... Verified on the Orin. A Shikoku extract yields only admin_level=4 prefecture rows with no country record, and drive_on_right=1 on every one, so tiles built against it route as right-hand traffic. The full Japan extract yields the JP country row with drive_on_right=0. The failure is silent, so every build now verifies the country row before tiles are considered usable.
