G1c FINO-style adapter: metadata guidance offsets SSL-globalization directionally (+0.014) but no CI-significant recovery; F1b not de-risked at adapter scale (honest)

position vs FINO (Meta FAIR, arXiv:2606.05107): orthogonal frozen-probe vs metadata adaptation; de-risks F1b; complementary experiment noted

consolidation: RESEARCH_OVERVIEW; figures w/ multi-seed error bars + cross-objective + closed-form law; polished 3 drafts (selector numbers, refs, figure callouts)
