Feb 1, 2026February 2026: Delivered two core features in selfxyz/self, focusing on maintainability and user actionability. The UUID Namespace was refactored to a constant, improving code clarity and reducing the risk of namespace drift across KycSuccessScreen and notification service. Introduced an Inactive Document Indicator with a reactivation flow, including a visual badge on the ID card layout and a guided onboarding path, enhancing user awareness and remediation speed. Minor fixes accompanying the inactive flow (lint cleanup and proving button reliability) contributed to stability. These efforts reduce maintenance overhead, improve the developer experience, and deliver clearer, faster user workflows with measurable business value.
