Excel export (from TWG feedback) - src/analysis/xlsx.js: a dependency-free XLSX writer — an .xlsx is a ZIP of XML, so this packs the required parts with a small stored-ZIP writer. Avoids SheetJS (stale npm package with advisories) and ExcelJS (heavy for an offline-first field app), and does not rely on the JSZip that only reaches us transitively via shp-write. Lazy-loaded as a ~5.6 kB chunk. - After a zonal run the Analysis panel offers "Export table (Excel)", writing a two-sheet workbook: Results (figures as real numbers) and Parameters (zone and input layers with feature counts, the "Apply to" scope, membership rule, statistics, numeric field and export time) — so a table can be verified or reproduced later rather than being an unattributed set of numbers. The button is hidden for overlay runs and cleared when the mode changes. - Verified against two independent readers: openpyxl loads it with zero warnings and correct numeric types, and LibreOffice Calc opens it as a spreadsheet. Also exercised end-to-end through the real zonal pipeline. COG raster entry point - Add External Layer gains a COG type alongside WMS/WFS/XYZ, with a URL pre-flight check that distinguishes a web page, a 404, a CORS block and a server without byte-range support — geotiff.js otherwise reports these only as an opaque "AggregateError: Request failed". Digital Earth Africa ETL - etl/deafrica_dem_to_minio.py exports a DE Africa DEM for a district as a COG and uploads it to the LUSPA MinIO bucket raster-objects, then verifies the object is anonymously readable and range-capable. Credentials come from the environment; the existing PHP integration hardcodes them and an earlier key pair reached Gitea. NOTE: not yet run against the Sandbox — start with --list-products to confirm the DEM product name. Documents - Concept note: Digital Earth Africa added as a raster source (§6.3), separating the live WMS route from the batch Sandbox export; corrected the in-house contour table's provenance to OpenTopography (gdal_contour over an SRTM 30 m / Copernicus 30 m DEM), and added the ToR §2.4.2 / FS §2 alignment chapter. - TWG presentation, architecture and two integration workflow charts (SVG sources kept in the repo so they stay editable), and a user guide for the Analyse tools. Service worker v13 -> v14. .gitignore: exclude Python bytecode from etl/. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
