The verification chain passes end-to-end at write-up time: './verify.sh' exited 0 — rebuild from source; term-by-term A038134 b-file diff below 10^6; deterministic reproduction (counts + FNV hash) of the two fixed high blocks [5e12, 5.01e12) and [9.99e12, 1e13); and 20 of 20 independent Miller-Rabin spot checks OK, covering sampled non-cluster witnesses, demoted-survivor witnesses, full cluster verdicts, and the anchors 97 and 11,519,999,994,329 — with one remaining caveat: the third fixed-block comparison, [0,1e9), prints 'skip' because that range was swept as three sub-blocks so no single results.csv line matches; additionally, differential validation of the production classifier against the structurally different v1 implementation is archived for a 2e8-wide block at 5e12 with identical counts and FNV hash.
