Jan 1, 2026Month: 2026-01 — Summary focused on stabilizing member form processing in svthalia/concrexit. Delivered a robust handling for missing 'length' field in member registration and renewal flows by adding validation, guards, and tests. This prevents crashes when data is incomplete, improves data integrity, and reduces downstream errors in onboarding and renewals. The work includes a targeted fix with code changes and tests, tracked under commit 45beae32188120c8426027ab9214788a3f00cbf8, including the following changes: Prevent crash on missing length field; added tests verifying the new behavior; included additional non-vibe-coded tests.
