data-us

Layer 1 data skill for the US market in the v2.0.0 three-layer architecture (Data / Analysis / Report). This skill is fetch-only — it does not analyze, score, or compose narrative. All output is structured JSON intended for direct handoff to a Layer 2 analysis-* skill or a Layer 3 report-* orchestrator.
