## ADDED Requirements

### Requirement: Retrieval evaluation SHALL provide live post-reindex acceptance
The retrieval evaluation system SHALL provide an opt-in live acceptance flow for validating retrieval behavior after embedding input changes require a knowledge-base reindex.

#### Scenario: Live acceptance requires a running service
- **WHEN** live retrieval acceptance is run
- **THEN** it SHALL call the configured Spring Boot retrieval endpoint
- **AND** it SHALL not be required by the offline fixture baseline

#### Scenario: Live acceptance records retrieval evidence
- **WHEN** a live retrieval case is executed
- **THEN** the report SHALL include the query, requested topK, result count, top candidate titles or sources, score labels, and raw response fields needed for review

#### Scenario: Reindex prerequisite is documented
- **WHEN** a developer prepares to validate breadcrumb-aware embedding behavior
- **THEN** the repository SHALL explain that existing vectors must be reindexed before live validation can reflect the new embedding text

#### Scenario: Live report is reviewable
- **WHEN** the live acceptance script completes
- **THEN** it SHALL write JSON and Markdown outputs that can be inspected or attached to interview evidence
