test: validate v1.1.2 on clean Apple Silicon macOS

Summary

Run v1.1.2 end to end on a genuinely clean supported Apple Silicon Mac and attach reproducible acceptance evidence.

Proposed Approach

• Use a clean Apple Silicon Mac with at least 16 GB RAM and no checkout or Answer Engine state.
• Download and verify assets anonymously.
• Complete dependency preflight, desktop/runtime launch, consented import, and grounded recall.
• Reboot and verify background recovery.
• Exercise repair, rollback, and uninstall/reinstall.
• Capture redacted evidence.

Acceptance Criteria

• Clean supported hardware and starting state are recorded.
• Assets download and verify anonymously.
• Dependencies are discovered or installed with clear consent.
• Desktop, API/UI, background service, import, and grounded recall succeed.
• Reboot, repair, rollback, and uninstall/reinstall match documentation.
• Evidence contains no secrets or personal content.

Start with the v1.1.2 assets and the documented dependency preflight on a clean supported Apple Silicon Mac. Exercise the desktop, API/UI, background service, import, recall, reboot, repair, rollback, and uninstall/reinstall flows; done means every acceptance criterion is recorded with reproducible, redacted evidence.
