Work through the True_Test_Matrix_Doc.md test cases systematically. For each test: 1) Run the app and perform the action, 2) Verify the expected outcome, 3) Mark Y (pass) or N (fail) in the document, 4) Add notes for any failures. Start from section 1 and work through each section. Use Playwright tests where possible to automate verification. When ALL 247 tests have Y/N results filled in, output TEST MATRIX COMPLETE
