From 740e19276768da083b17cdf2f50549de8c6592ac Mon Sep 17 00:00:00 2001 From: mavrick Date: Fri, 30 Oct 2026 02:27:21 -0500 Subject: [PATCH 1/2] test(engine): run everyday jobs end to end, and on Census data nightly workflows.rs joins a CSV to parcels by leading-zero ids, overlays zoning, totals area by zone against the closed-form ellipsoid area, exports a map, saves, reopens and exports GeoPackage and CSV. A saved model gives byte-identical output in two sessions and after a reopen; bad input stops it and leaves the project untouched. An ignored case checks Shelby County's 249 census tracts against the areas the Census Bureau publishes; nightly downloads the pinned files and runs it.

The tract check allows a square metre of rounding on top of 1e-5.
