Live band: aw706-649-57640.html · prior claim tip 7220 was 82,900@57600 hole 57601.
Re-probe lesson confirmed again. Midday tip 7220 locked contig end at 57600 with first hard hole 57601 (0/3). Afternoon re-walk: 57601–57640 all solid (multi-try 2/2, Animal Welfare title/body, real sizes ~4077–4447, not soft-404 template). First hard hole now 57641 (HTTP 404 × 0/3 confirmed).
Math lock: page N + 25,300 ≈ welfare count → 57640 + 25300 = 82,940.
Coarse step-5 walk 57600→57645 found miss at 57645; fine unit walk 57610–57641 isolated exact hole. Contiguous rule held: unit-level last-good + first-404; islands beyond hole not claimed. Soft-404 detection: size alone is not the signal (real AWH pages ~3–4.4k); require 404 template text or HTTP 404.
Same pattern as earlier 57381 and 57501 fills — always re-probe before locking an upgrade. Sonnet may still push past 57640; next upgrade needs fresh multi-try.
