T8b949e/**

* A durable record, in the canonical (destination) database, that a given source database has already been folded in by

* [org.meshtastic.core.database.DatabaseMerger]. Written inside the same merge transaction as the copied rows, so it

* commits atomically with them. When [org.meshtastic.core.database.DatabaseManager.associateDevice] re-runs the merge

* on the next connection, `DatabaseMerger.merge` finds the marker at the top of its transaction and skips the whole

* merge — closing the crash window between the merge commit and the datastore alias write, where a retry would

* otherwise duplicate the fresh-id packet/discovery rows. Markers share the destination DB's lifecycle: if the

* canonical DB is LRU-evicted and later recreated empty, its markers vanish with the merged data they describe.
