My Lovable Project is already built out; I’m now at the stage where only the final touches stand between it and launch. The design is locked, so the focus is purely on Functionality and features as well as Testing and bug fixing. What I need from you • Complete and harden User authentication—registration, login, password reset, and session handling must be airtight. • Finish Data management tasks, ensuring that all create-read-update-delete flows are solid, validated, and persist correctly. • Run a full round of manual and automated tests, then squash every bug you uncover until the build is clean. Acceptance criteria 1. All authentication scenarios succeed without exposing security issues or edge-case failures. 2. Data operations perform reliably, with proper error handling and no data loss. 3. The test suite passes 100 %, and no critical bugs remain in the issue tracker. Hand off the updated code, a concise change log, and any new test scripts so I can push straight to production.
