Hosts connect their Google account. Events on the calendars they choose block their availability, kept current by push notifications and a renewal cron. Confirmed bookings are written to their calendar as events, with Google Meet links when asked. Firestore and Supabase/Postgres are both carried.

The design turns on keeping the two directions apart. **Busy time is a disposable mirror of a time window, rebuilt by a full resync and diffed by deterministic ids. Booking events are addressed by an id derived from the booking, and never read back as busy time.**
