# Traceability Matrix

| Field | Value |
|---|---|
| **Document** | Traceability matrix — `SYS-*` → `REQ-*` → design → test |
| **DRD ref** | ECSS-E-ST-40C Rev.1 traceability requirements (Annexes B/C/D <7>, F <6>); ECSS-Q-ST-80C Rev.2 §6.2.6 |
| **Container** | Design Justification File (DJF) — `compliance/traceability/` |
| **Project** | `sar-processor` (gitlab.eopf.copernicus.eu/ipf/sar-processor) |
| **Software criticality** | Category C (ECSS-Q-ST-80C Rev.2 / ECSS-E-ST-40C Annex R) |
| **Baselined at** | PDR (living document, frozen at each review) |
| **Status** | Draft for SRR — skeleton |

> Single cross-document traceability record. Populated as requirements land (SRR/PDR) and closed
> out at QR (every `REQ-*` → verification result).
