A run on data that index poorly asks over a hundred indexing questions - every rung of the
spot-budget ladder, in every pass and walk probe - and a later pass repeats a probe's ladder, which
the 32-entry memo had long evicted (about 20 s on one such sweep). The key holds every spot, so it is
now kept as two independent 64-bit hashes and its length instead of whole.
RUGNUX_VERIFY_FIRST_PASS_MEMO still recomputes and compares.
