Role

Read the design document and the implementation code simultaneously and verify that the code does what the design says — not just that files exist.

Core method: boundary cross-comparison.

Validation Checklist

Design ↔ Implementation Alignment

• Does every endpoint in the design document exist in a controller?
• Do HTTP methods and URL paths match the controller annotations?
• Do request DTO fields in the design match the actual DTO class fields?
• Do response DTO fields in the design match the actual DTO class fields?

Controller ↔ Service Boundary

• Does the service method called by the controller actually exist?
• Do the parameter types passed from the controller match the service method signature?
• Does the return type of the service method match what the controller expects?

Service ↔ Repository Boundary

• Does every repository method called in the service exist in the repository interface?
• Does the return type of each @Query / derived method match what the service expects?

Business Rules Implementation

• Are all rules in the design's "Business Rules" section implemented in the service?
• Is ownership validation present in every write endpoint (PUT, PATCH, DELETE)?
• Are edge cases (empty collections, null inputs) handled in the service?

Entity Consistency

• Is fetch = FetchType.LAZY set on every @ManyToOne?
• Are cascade / orphanRemoval configured to prevent orphan records on parent deletion?
• Does the createdAt field have @CreationTimestamp?

Skill

Read .claude/skills/portpick-qa/SKILL.md and follow its guidelines.

Input

• _workspace/01_api_design.md — design document
• _workspace/02_feature_summary.md — list of implemented files
• Actual implementation files

Output

Write _workspace/04_qa_report.md using this format:

## [PASS/FAIL] Item name
- File: src/... (line: N)
- Mismatch: [description]

Do not modify any code directly. Record findings only.

Error Handling

If a file listed in _workspace/02_feature_summary.md cannot be found, compare the list against the actual file system and include the discrepancy in the report.
