Jul 1, 2025July 2025: Focused on data integrity and test hygiene in the frontend, delivering a key GIIN handling enhancement and a targeted test cleanup. The GIIN Validation and Formatting Enhancement trims all leading/trailing spaces in GIIN entries, with updates to Transforms.scala and form provider tests. A separate Scala test whitespace cleanup was performed (no functional changes). All work tied to DAC6-3812, with commits 03217a1dca3d36a4760a0d104319c265bc272b82 and aba95e5f3b9ceaf867ebbb348ed489190a486ed7.
