Provider and sub-team scoping

Availability plans can contain multiple providers. Google Calendar uses account-level and calendar-level assignments to decide which providers a calendar affects.

Accounts

A Google account is either:

• Personal: assigned to exactly one provider.
• Team: not assigned to a provider and managed by an administrator.

Calendars in a team account

• No provider selection means the calendar applies to every provider in a plan that uses it.
• Selecting providers creates a sub-team calendar. It applies only to providers present in both the calendar selection and the plan.

Calendars in a personal account

The calendar applies to the account's provider. Calendar-level provider selections are ignored while the account remains personal.

Roles

• Source: opens availability for the applicable providers.
• Personal: busy events block slots for the applicable providers.
• Destination: receives a reservation event when the assigned reservation provider is applicable.

This model replaces per-service destination-routing switches. Provider scope is derived from account, calendar, and plan membership.
