FA-98564 / KV cache position mapping / Member archive
Paged cache resolves through the sequence block table · case 04
A logical page is represented by its local offset instead of the physical slot in that page.
Case contract
block_table maps logical page number to physical block base. Return base + (position modulo page_size). Missing page returns -1.
Why this case matters
A small in-memory model makes the cache address contract explicit for a serving component.
One recorded failure
