How to use this answer
Publish save-transfer steps only after Natsume or a platform listing defines them and a reproducible test confirms them.
Check the dated first-party source.
Separate the confirmed fact from platform, retailer, or story assumptions.
Recheck the live listing before acting on changing data.
What this does not confirm
