Notes from building Spacepal: how it works, what macOS makes hard, and what testing found.

• Which of my Claude Code sessions is waiting for me? (13 November 2026): using Claude Code hooks to mark the desktop whose session needs you, jumping to its terminal, and the idle-prompt mistake from the first day.
• Bringing Claude Code sessions back to the right desktop after a restart (9 November 2026): finding which terminal belongs to which Space, waiting for apps to come back, and the bug a real restart test found.
