+# EvidenceLocker
+
+**Status:** Implemented
+**Source:** `src/EvidenceLocker/`
+**Owner:** Platform Team
+
+## Purpose
+
+EvidenceLocker provides sealed, immutable storage for vulnerability scan evidence and audit logs. Ensures tamper-proof evidence chains for compliance and forensic analysis with content-addressable storage and cryptographic sealing.
+
+## Components
+
+**Services:**
+- `StellaOps.EvidenceLocker.WebService` - HTTP API for evidence submission and retrieval
+- `StellaOps.EvidenceLocker.Worker` - Background sealing and archival workers
+
+**Libraries:**
+- `StellaOps.EvidenceLocker.Core` - Evidence sealing, verification, and chain validation
+- `StellaOps.EvidenceLocker.Infrastructure` - Storage adapters and evidence bundle management
+
+## Configuration
+
+See `etc/evidence-locker.yaml.sample` for configuration options (if available).
+
+Key settings:
+- Storage backend (filesystem, object storage)
+- Sealing policy (immediate vs. batch)
+- Retention policies
+- Export destinations
+- Authority integration for access control
+
+## Dependencies
+
+- PostgreSQL (schema: `evidence_locker`)
+- Authority (authentication and authorization)
+- Signer (cryptographic sealing operations)
+- ExportCenter (evidence bundle export)
+
+## Related Documentation
+
+- Operations: `./operations/` (if exists)
+- ExportCenter: `../export-center/`
+- Attestor: `../attestor/`
+- High-Level Architecture: `../../07_HIGH_LEVEL_ARCHITECTURE.md`
+
+## Current Status
+
+Implemented with WebService and Worker components. Supports sealed evidence storage with cryptographic verification. Integrated with ExportCenter for audit bundle generation.
