bq. Is there a simple way to create a situation where a repair requires
streaming?
The easiest way is to nuke one node after writing data to all nodes.
So, for example, you create 3 nodes cluster, create keyspace with RF=3, fill
data in, clear one node(ccm node1 clear), bring it up again, then repair.
bq. Somehow the streaming repair is getting done somewhere other than
Differencer#run.
Differencer creates StreamingRepairTask at the end which creates StreamPlan and
executes.
In order to log streaming, you can add StreamEventHandler to catch streaming
events.
For mode detail see http://wiki.apache.org/cassandra/Streaming2.
For example, BulkLoader/SSTableLoader uses StreamEvent to track progress.

> I think it would be nice to log repair stats and results like query tracing
> stores traces to system keyspace. With it, you don't have to lookup each log
> file to see what was the status and how it performed the repair you invoked.
> Instead, you can query the repair log with session ID to see the state and
> stats of all nodes involved in that repair session.
