01
Model shared user identity with an abstract User and a Role enumeration to keep cross-organization roles explicit.
02
Separate InternshipPlacement, AttendanceRecord, and EvaluationReport as distinct aggregates linked by association rather than inheritance.
03
Use composition from EvaluationReport to EvaluationCriterion because criteria exist only within a report.
Reuse for any internship or work-integrated learning platform that must track placement, daily attendance, approvals, and multi-role evaluations across organizations.
