+# SPRINT_4300 Summary - Explainable Triage Gaps
+
+## Overview
+
+This sprint series closes the remaining gaps between the "Designing Explainable Triage and Proof-Linked Evidence" advisory (18-Dec-2025) and the current implementation.
+
+**Origin Advisory:** `docs/product-advisories/18-Dec-2025 - Designing Explainable Triage and Proof‑Linked Evidence.md`
+
+**Gap Analysis:** `docs/implplan/analysis/4300_explainable_triage_gap_analysis.md`
+
+## Executive Summary
+
+**IMPORTANT: This summary file describes the ORIGINAL plan from advisory 18-Dec-2025.**
+
+**The ACTUAL implemented sprints under SPRINT_4300 are DIFFERENT and focus on moat hardening features:**
+
+| Sprint | Title | Status | Tasks |
+|--------|-------|--------|-------|
+| 4300.0002.0001 | Unknowns Budget Policy Integration | ✅ DONE | 20/20 |
+| 4300.0002.0002 | Unknowns Attestation Predicates | ✅ DONE | 8/8 |
+| 4300.0003.0001 | Sealed Knowledge Snapshot Export/Import | ✅ DONE | 20/20 |
+
+**Total Tasks Completed:** 48/48 (100%)
+
+---
+
+## ORIGINAL Plan (Not Implemented)
+
+The advisory defined a comprehensive vision for explainable, evidence-linked triage. **~85% was already implemented** through prior sprints (3800, 3801, 4100, 4200 series). This series addresses the remaining **6 gaps**:
+
+| Gap | Description | Sprint | Priority | Effort |
+|-----|-------------|--------|----------|--------|
+| G1 | CLI attestation chain verify command | 4300.0001.0001 | HIGH | M |
+| G6 | Findings evidence API endpoint | 4300.0001.0002 | MEDIUM | S |
+| G2 | Evidence privacy controls | 4300.0002.0001 | MEDIUM | M |
+| G3 | Evidence TTL enforcement | 4300.0002.0002 | MEDIUM | S |
+| G4 | Predicate JSON schemas | 4300.0003.0001 | LOW | S |
+| G5 | Attestation completeness metrics | 4300.0003.0002 | LOW | M |
+
+**Note:** The above gaps from the original plan were not implemented under SPRINT_4300.
