IHistorianDataSource.SupportedAggregates (default: every HistoryAggregateType) is the one authority for both ServerCapabilities/AggregateFunctions (i=2997) and HistoryServerCapabilities/AggregateFunctions (i=11201) and for the up-front BadAggregateNotSupported in HistoryRead-Processed. Gateway declares AggregateModeMapper.Served (4), SqlServer/QuestDB AggregateFamilies.Served (17), Null none. Only the folder references are trimmed; the SDK's calculator factories stay so live AggregateFilter subscriptions keep working. Co-Authored-By: Claude <noreply@anthropic.com>
