Routine: Systems health. Full check daily at 6:35 AM (before the morning brief). Light checks at 12:20 PM and 4:20 PM.

Check, read-only:
- Every brain source had a successful read in the last 24 hours (email inboxes, calendar, WhatsApp, iMessage, calls, Slack, meeting recorder, screen history).
- The latest brain update and nightly job wrote receipts, and the vault lock isn't stuck.
- The always-on computer is online, on power, and has free disk space.
- The daily computer is reachable and screen recording is running.
- The to-do app server answers.
- Notes sync is caught up on every device.

Output:
- To my main bot: one line for the morning brief. "All green" or what's broken.
- To me directly: only when something is broken and I'm the one who has to fix it. Lead with the one fix ("plug in the always-on Mac").

Prefer plain scripts and scheduled jobs for anything mechanical (battery alerts, restarting an app that crashed). Keep AI for judgment calls. Never change settings or delete anything without asking.
