arm64 is no longer a risk: verified end to end on mikkeli-orin-nano-2
(L4T R36.4.7). The official image publishes linux/arm64, runs natively, and
the full pipeline works including a served route.
Corrects the Japan guidance. Advising a regional extract was wrong for the
admin build: driving side is a country-level property, and a Shikoku extract
produces no country row and drive_on_right=1, silently giving right-hand
traffic routing. Admins must come from the full extract; routing tiles may
still come from a region.
Decision 14 closed: recordings bounded with rotation, enforced by the writer.
