Here’s what I need from you:

• Analyse the current call flow that surrounds login, token handling, and any guard clauses already present (if any). • Design and inject the new authentication and role-based authorization logic entirely in smali, keeping method naming and class locations consistent with the current package structure. • Ensure the modified code assembles cleanly with apktool, signs, and runs without crashing on Android 8-13. • Provide clear inline comments so future maintenance is straightforward and include a short changelog outlining every touched file.
