 ## Simulation vs production
 
-- The CronJob compresses "drone lands, docks, offloads, prunes" into a
-  periodic rsync-style copy. Production offload is event-driven per docking
-  and verifies checksums from the flight's partition manifest before pruning
-  the on-board lake.
-- MinIO credentials here are throwaway defaults; production credentials are
-  sealed per site and never in state or VCS.
+- Sim CronJob: `cp -ru` + `mc mirror` on a schedule — shortcut for "lands, offloads, prunes". Production: event-driven per dock, rsync or `mc mirror`, checksum audit before prune ([03 — Data platform](../../../docs/03-data-platform.md)).
+- MinIO credentials here are throwaway defaults; production credentials sealed per site, never in state or VCS.
