Under the hood
Human accounts outside the organization are now marked with an 'outside' flag in serialized account data
What
When a human account is flagged internally as being outside the organization, that fact is now included in the serialized account object as outside: true. The corresponding data schema gained a matching optional outside field alongside the existing access field.
Why
This lets other parts of the system (such as artifact or comment handling) know when an account belongs to someone outside the org, which was not previously exposed.
