Nov 1, 2025November 2025 monthly summary for betagouv/france-chaleur-urbaine: Delivered targeted business-value updates across data metrics, developer experience, spatial data integrity, and API reliability. Key features/updates include: (1) Statistics data update for November 2025 to reflect current metrics (CO2 tons, connections, iFrame integrations, housing units, last activity date); (2) Enabled ErrorLens extension to improve in-editor error visibility and developer experience; (3) Spatial data validation and cleanup with geometry validation, a helper to map GeoJSON types to PostGIS dimensions, and a migration to fix invalid geometries ensuring data integrity for spatial operations; (4) Bug fix to eligibility status API return value by refactoring eligibility status and city network routes, removing redundant type conversions and correcting eligibility checks. These changes were implemented via commits fb07d5e26cc89a0d2bf7e696c1b3805fa440083f; b913bd32add450d269a2d620aa069f845afd68e8; 10418ca2605fb079da4be2876a74c63511f917be; 68981ae34039feab343a882b7c0297affe00ffea; c616af572a076949498bb34747886d1d66186d9b. Overall impact includes more accurate operational dashboards, faster debugging, robust spatial data processing, and reliable eligibility outcomes, enhancing decision-making and user trust.
