Local Buffer
The Local Buffer is the durability boundary of the gateway. Every reading the Driver Loader produces is committed here before anyone tries to send it. If the network is down, the box reboots, or the cloud is slow, the data waits safely on disk and replays in order.
Storage profile
An embedded SQLite database on the gateway’s local flash. A rolling budget of ~512 MB / 72 hours bounds wear and disk use; once the cloud acknowledges a batch its rows are pruned.
