OSINT Argus — Gemma 4 12B QAT, unified news + social OSINT (W4A16, tri-modal)
All numbers on this card are measured on the deployed int4 artifact (previous cards quoted bf16-checkpoint numbers; the int4 reality is ~10pp lower on schema tasks — that discrepancy was the programme's audit finding A1, now fixed).
Unified build (2026-09): full-parameter QAT on the unified trunk — no adapter, no merge. Lineage: social-media soup (25-Aug) -> news track v20/v21 (120,747-record corpus: 40% news core — article veracity in Bengali/Hindi/Urdu/25-language x-fact + Reddit-format Fakeddit, FEVER-family claim adjudication, XL-Sum summaries in 9 languages, article political bias — plus full social/multimodal replay). Exported through the corrected int4 grid (earlier revisions shipped fq(fq(W)); fixed 31-Aug, verified lossless: baked-checkpoint == export). Selected over v20/v22 and the deployed soup-int4 on combined social/multimodal + news gates.
