transactionWithResult

updateReadForEntities

fun updateReadForEntities(readAt: Long, entity_name: String, entity_keys: Collection<String>)

Bulk-updates entity.read_at for entity_keys. An empty collection is a deliberate no-op: SQLite rejects IN () as a syntax error, and KeyValueStorage.updateReadAt routinely passes an empty list when a selectAll(...) Flow emits an empty result set.
