Major - P3 The ingest table is not backed by the SLS so it should never be set with the WT_BTREE_DISAGGREGATED flag. However, when MongoDB creates the layered cursor, it uses the "block_manager=disagg" config. This config passes to the ingest table creation as well and causing it to be set with the WT_BTREE_DISAGGREGATED flag.
