.alog, RoasTime, Cropster — plus any CSV. Your existing roasts sit alongside your RoastSource historyRoast with Artisan driving the probe, as always. Then RoastSource holds everything around it: which green you used and how much is left, how the cup scored, what blend it went into, and what to change next batch. When import ships, the .alog comes along automatically.
Nothing to install, nothing to configure, nothing to cancel.
