+USDA Phytochemical & Ethnobotanical Database — Enriched v2.0
+=============================================================
+
+This archive contains the complete enriched dataset (104,388 records, 24,771
+unique compounds, 2,315 plant species). Each record includes the original USDA
+Dr. Duke's baseline fields (chemical, plant_species, application, dosage) plus
+four quantitative enrichment layers: PubMed citation count (March 2026 snapshot),
+ClinicalTrials.gov study count, ChEMBL bioactivity measurement count, and US
+patent count since 2020 from USPTO PatentsView.
+
+Files included:
+  - ethno_dataset_2026_v2.json      Full dataset (compact JSON, ~23 MB)
+  - ethno_dataset_2026_v2.parquet   Full dataset (Snappy Parquet, ~975 KB)
+  - MANIFEST_v2.json                SHA-256 checksums, record count, field stats
+  - ethno_sample_400.json           400-row reference sample (same schema)
+
+Data sources: USDA Dr. Duke's Phytochemical Database (public domain), NCBI PubMed
+(E-utilities API), ClinicalTrials.gov (bulk XML), ChEMBL 35 (SQLite), USPTO
+PatentsView (bulk TSV). All enrichment pipelines are deterministic, checkpoint-
+resumable, and ran locally against downloaded bulk data — no rate-limited API
+calls. Enrichment completed March 2026.
