Protected behavior

Project creation cannot produce an empty or leaderless aggregate; direct membership rejects ineligible or duplicate current members; leadership changes leave one current term; activation is owning-Mentor-only and rejects invalid Task assignees.

Test method

Plain JUnit drives the aggregate through its public factory and mutation methods. It asserts externally observable state and denials without Spring or database infrastructure.

Hand-derived expected result

A planned Project starts with one current membership and one current leadership term. Adding a different eligible Intern yields two current memberships. Changing Leader closes one term and opens one term while retaining both memberships. Activation changes only PLANNED to ACTIVE when every supplied guard is true.
