Privacy protection in harbour apps

I've read that jolla applies several restrictions to apps that are being released in the harbour (some of these restrictions are mentioned in https://harbour.jolla.com/faq), but what are those restrictions precisely? Can an harbour app e.g. 1. Access the contacts ? 2. Access the calendar ? 3. Access Emails ? 4. See which email accounts (email addresses and passwords) are configured ? 5. Access the clipboard ? 6. Run other apps ? 7. Scan nearby wifi hotspots ? 8. Access configured wifi hotspots (username, password, BSSID) ? 9. Read phone and SIM identifiers (IMEI, IMSI, ... ) ? How does jolla check whether an closed source app complies with these restrictions?
