# Phase 42 Verification

## Status

passed

## Requirements

| Requirement | Description | Status | Evidence |
| --- | --- | --- | --- |
| `REQ-SRC-01` | Add more durable source identity and cross-topic source recognition. | passed | Source identity support landed on the remediation branch and the integrated source-intelligence regression slice passed. |
| `REQ-SRC-02` | Strengthen citation graph and source-neighbor signals. | passed | Citation/source-neighbor signals were exposed through `L0` projections and the integrated regression slice passed. |
