Technically, yes it's a side mission - but you don't get a chance to refuse it - so it behaves like a storyline mission, with a time limit.

It's fuck-upable too because of its conditionality (see task manager.ltx) so my contention is that it IS storyline because you get to a certain point and presto Sid gets on the horn and asigns it.
