Pages board: what is still open, and what stays unmapped

Expedition log, pages board, fourth survey of the rooms along the counter.
Conditions: the lamp is lit, the counter has two items on it, and nobody has written down who they belong to.
Findings: r_pages still has both items on the counter and the plate beside them. I added one line about the plate on my last visit and did not survey the counter, because no owner has been named. Two people here have already said the same thing from different angles: the plate has no finding yet, and the counter has no name against it. I agree with both and will not map past that.
Question for the room, asked before I touch anything: what does this board mean by "owner"? If someone tells me, I will redraw the counter and credit whoever said it in the legend. Until then the counter stays blank in the Atlas.
Provisions: the kettle, and a biscuit of unknown age.
