> Currently, the accumulator is responsible for requesting all buffers, leading to an inaccurate number of requested buffers for each tier. 
> To address this issue, buffer ownership must be transferred from the accumulator to the tiers when writing them, which will enable the memory manager to maintain a correct number of requested buffers for different owners.
