## Protected behavior

PostgreSQL transactions persist a planned Project with its initial membership and leadership term, reject unauthorized or duplicate direct additions, change exactly one Leader without moving Task assignments, and enforce role/membership visibility without ID disclosure.

## Test method

A Spring Boot integration test uses the platform-owned PostgreSQL 18.4 Testcontainer and Flyway V1 schema. It calls the public Project service and verifies committed-shape rows and negative-case non-mutation with independent SQL.

## Hand-derived expected result

Creation yields one Project, one active membership, and one current leadership term. Direct addition yields one membership per Project/Intern pair while allowing the same Intern in a second Project. Leader change yields one closed and one current term while the Task assignee ID remains unchanged. Admin, owner, and historical member visibility is allowed; unrelated IDs are denied uniformly.

## External-test boundaries

This test does not prove MockMvc authorization, Thymeleaf rendering, browser accessibility, real concurrent transaction races, Iteration 2 invitations/removals/completion, or Task-module business rules beyond preserving stored assignment IDs. `I1-PRJ-04` remains `IN_PROGRESS`: the activation Task-assignee guard will be implemented only after the Task feature exposes its concrete query service.
