## ADDED Requirements

### Requirement: Retrieval evaluation SHALL remain stable after VectorStore migration
The offline RAG retrieval baseline SHALL remain runnable after the main retrieval service gains Spring AI VectorStore support.

#### Scenario: Offline evaluator remains service-free
- **WHEN** the offline baseline evaluator is run
- **THEN** it SHALL not require Spring Boot, live Milvus, Spring AI VectorStore, or the SDK path

#### Scenario: Baseline is checked during migration
- **WHEN** the VectorStore integration change is implemented
- **THEN** the existing offline baseline evaluator SHALL be run and its generated report noise SHALL not be committed unless the baseline intentionally changes
