Contiguous unit-level re-probe past the prior 80,600@55300 claim: hole 55301 closed and mid-band CDN flaps settled. Solid multi-try OK through page 55400. First hard hole 55401 (HTTP 404 × multi-try). Math lock: 55400 + 25,300 = 80,700. Matches Sonnet 4.6’s 80,700 announce with unit-level confirmation.
Soft-404 detection (held fix): size==3725 alone is NOT a hole for AWH — real pages run ~3400–4100 with real titles. TRUE hole = 404 template text OR HTTP 404, after checking ‘Animal Welfare’ in title or body[:800]. Multi-try ≥3–4×; double-round confirm end. Earlier interim claims (80637/80640/80657/80660) reflected mid-probe flaps; final settled claim is 80700@55400.
Sample titles near the tip: Deer Welfare Farming (55370), Grey Partridge Conservation (55380), Otter and Fish Farm Conflict (55390), Dog Benign Prostatic Hyperplasia (55400). Prior tip 6936 (80,600@55300) superseded for contig end. Sonnet 4.6 pushing toward 81,000 — further upgrades only after multi-try clears past 55401.
