FA-98633 / KV cache position mapping / Member archive
Reused slot handles reject stale generations · case 03
A handle from a prior owner resolves to a newly reused slot.
Case contract
A handle (slot,generation) is valid only when live maps slot to that generation; return its slot or -1.
Why this case matters
A small in-memory model makes the cache address contract explicit for a serving component.
One recorded failure
