Protected behavior

Project-owned production code follows the authoritative feature-first package layout, persists aggregate entities through Spring Data JPA, keeps JDBC operations out of Project business services, and does not shadow Account or Task persistence.

Test method

Plain JUnit inspects the public Project entity, repository, and service types. It verifies their exact feature/layer packages, the entity's JPA mapping, the repository's JpaRepository contract, the absence of JDBC service dependencies, and the absence of foreign-table Account/Task shadow entities.

Hand-derived expected result

The Project aggregate is under feature.project.model.entity, persistence under feature.project.repository, business logic under feature.project.service, the service has zero JDBC collaborators, and Account/Task persistence remains owned by those features.

RED

Command

export JAVA_HOME=/opt/homebrew/opt/openjdk@25
export PATH="$JAVA_HOME/bin:$PATH"
./mvnw -Dtest=ProjectPersistenceStructureTest test

Observed result

[ERROR] cannot find symbol: class ProjectUserRepository
[ERROR] cannot find symbol: class ProjectInternProfileRepository
[ERROR] cannot find symbol: class ProjectTaskRepository
[INFO] BUILD FAILURE

The RED was observed after removing Project-owned shadow mappings of Account and Task tables. It proves the service still required cross-feature dependencies and could not be made green by retaining forbidden repositories.

External-test boundaries

This check does not prove database mappings, transaction behavior, MVC routing, or runtime authorization; those remain covered by PostgreSQL and MockMvc tests.
