Your agents keep working with the lid closed. Opening it tries to undo everything in this log.

Recovery.

Every change goes into a journal on disk before it happens, so it can be undone even after a crash.

If the menu shows a recovery warning, fix it before you leave the Mac alone.

prompt

Install the latest stable Insomnia release by following https://github.com/krishhgg/Insomnia/blob/main/skills/install-insomnia/SKILL.md. If a step needs my password, give me the command to run in Terminal.

Or follow docs/install.md. It adds a sudoers rule, so read what it installs first.

Insomnia is experimental. Recovery can fail, and a timer is not a safety guarantee. Keep the Mac on a stable, ventilated surface, never in a closed bag. Validation status
