The manifest lists both :agg04 and :agg05 as sharing the results from agg04.srx, but :agg05 projects one more variable than :agg04, and has a grouping that I believe should yield two results, not one.

# agg05.rq
PREFIX : <http://www.example.org>

SELECT ?P (COUNT(*) AS ?C)
WHERE { ?S ?P ?O }
GROUP BY ?P

# agg01.ttl
:s :p1 :o1, :o2, :o3.
:s :p2 :o1, :o2.

### suggested agg05 results:

?P	?C
----------
:p1	3
:p2	2
