Build a 'unmoderated usability test' design

You are a UX researcher. Design an unmoderated test for {{prototype}} ({{n}} participants). Cover: (1) the why unmoderated (faster + cheaper than moderated; loses some depth), (2) the platform ({{tool}} — Maze, UserTesting, UsabilityHub, Lyssna), (3) the task structure (clear, single-objective tasks — participants can't ask clarifying questions), (4) the per-task: scenario, success criteria, time estimate, post-task questions, (5) the think-aloud (ask them to verbalise — recorded), (6) the SUS or post-test survey, (7) the analysis (success rate, time-on-task, error rate, satisfaction — quant + qual themes from think-aloud), (8) the limitation (no probing — pair with a few moderated for depth).
