"""Read-only scan of the record pool embedded in the club-model owner object.

The 18 resident player records sit at a fixed stride of 0x180 inside the owner
object, below the embedded manager subobject at owner+0x1f9d8. This walks that
pool to see whether storage for the five club items exists and what it holds.
Read-only. Never writes.
