The notice for the oath typically states that the applicant must bring the supporting documents much the same as to the test and interview.
In practice, however, it appears that oath officials only check and collect the PR card . . . that is how it went at my oath ceremony as well.
I brought the documents as instructed, and had a couple of them in hand, and the official (same woman as who interviewed me two days earlier at test event) said "all I need is your PR card." Same for those in line in front of me, and following me.
And the reports in forums are generally consistent with that as well.
Nonetheless I would bring all documents instructed but not be concerned about any further review let alone assessment of them.
Note, however, it is not over until the oath has been taken. Probably better to not take much for granted.
Mostly, however, show up, deliver the PR card, take the oath, enjoy the day.
