+# SPRINT 3200 - Attestation Ecosystem Interop - Implementation Status
+
+> **Date:** 2025-12-23
+> **Status:** Phase 1 Complete (Standard Predicates Library)
+> **Progress:** 35% Complete
+
+---
+
+## Executive Summary
+
+**Strategic Objective:** Position StellaOps as the **only scanner** with full SPDX + CycloneDX attestation support, capturing the market opportunity created by Trivy's incomplete SPDX attestation implementation.
+
+**Current Achievement:** Core foundation library (`StellaOps.Attestor.StandardPredicates`) implemented and building successfully. This library enables StellaOps to parse and extract SBOMs from third-party attestations (Cosign, Trivy, Syft).
+
+**Next Steps:**
+1. Integrate StandardPredicates into Attestor service
+2. Extend BYOS to accept DSSE-wrapped SBOMs
+3. Implement CLI commands for attestation workflows
+4. Complete documentation suite
+
+---
