Instance methods

bump_age

Shared across worker threads in think_smp (each searcher's own @tt is the same instance) — must be a real atomic RMW. A plain UInt8 field bumped from multiple threads concurrently can lose increments or hand out a torn read to store's replacement-policy check, both of which are silent correctness bugs, not just noise.
