+# STAF data: the browser mirror
+
+The data the static STAF web app (EASI, SFARI and DEEP; the Stream Tiered Assessment Framework,
+https://usace-wrises.github.io/staf/) reads by HTTP range. Every file mirrors an asset of a GitHub
+release of https://github.com/USACE-WRISES/staf, which stays the source:
+
+- `bundle/`: the STAF data bundle (`staf-data-current`), unzipped: NHDPlus HR flowlines, catchments
+  and their shared borders, precomputed per-catchment values, the NHDPlus V2 crosswalk with
+  StreamCat, and national point tables (WQP, NID, NWIS, NAS), for the lower 48.
+- `xs/`: the national cross-section grid (`staf-xs-current`, published region by region): every
+  section's scoring numbers, what drawing or pulling a section needs, one profile per segment.
+- `library/`: the STAF assessment library (`library`): DEEP's regional assessments, calculators and
+  EASI's method packages.
+
+Files are stored under content-hashed names and never change in place; `web-manifest.json` (updated
+last) maps each logical name to its file, size and sha256. Built from public federal datasets (USGS,
+EPA, USACE, NOAA, USDA, FWS); see the STAF repository for sources and methods.
