+# Lineage UI Sprints - Status Assessment
+
+**Date:** 2025-12-29
+**Assessment:** Comprehensive review of all pending UI sprints
+
+---
+
+## Executive Summary
+
+The StellaOps lineage UI has **36 component files** already implemented with ~70-80% functionality complete. Most components exist but need:
+- ✅ Final polish (styles, dark mode, accessibility)
+- ✅ API wiring verification (some already done)
+- ⚠️ Missing: A few specific components (Node Diff Table, Pinned Explanations UI)
+
+**Quick Win Opportunity:** Complete the remaining 20-30% to deliver a fully functional lineage experience.

+
+## Critical Path to MVP
+
+### Phase 1: P0 - Essential (3-5 days)
+
+1. **Complete Explainer Timeline** (1-2 days)
+   - Add missing SCSS styles
+   - Implement copy-to-clipboard logic
+   - Add dark mode support
+   - Basic accessibility (ARIA labels)
+
+2. **Build Node Diff Table** (2-3 days)
+   - Create component from scratch
+   - Wire to diff API
+   - Add expand/collapse rows
+   - Style with table/grid layout
+
+3. **Verify API Wiring** (0.5 days)
+   - Test all API endpoints
+   - Add export POST call
+   - Verify error handling
+
+### Phase 2: P1 - High Value (4-6 days)
+
+4. **Complete Reachability Gate Diff** (2-3 days)
+   - Add gate chips
+   - Add path comparison
+   - Add confidence bar
+   - Style and polish
+
+5. **Build Proof Studio** (3-4 days)
+   - Create proof chain viewer
+   - Add fact display
+   - Wire to API
+   - Export functionality
+
+### Phase 3: P2 - Nice-to-Have (3-4 days)
+
+6. **Complete Audit Pack Export** (2-3 days)
+   - Format selector
+   - Signing options
+   - Progress tracking
+   - Merkle display
+
+7. **Build Pinned Explanations** (2-3 days)
+   - Pin/unpin UI
+   - Local storage
+   - Export to markdown
+
+---
+
+## Recommended Immediate Actions
+
+### 1. Complete Explainer Timeline (Highest ROI)
+- **Why:** 70% done, high visibility feature
+- **Effort:** 1-2 days
+- **Files to modify:** Add SCSS, implement copy logic
+
+### 2. Build Node Diff Table (Most Critical)
+- **Why:** Core comparison workflow, P0 priority
+- **Effort:** 2-3 days
+- **Files to create:** New component from scratch
+
+### 3. Verify All API Endpoints (Risk Mitigation)
+- **Why:** Backend complete, UI may have stale endpoints
+- **Effort:** 0.5 days
+- **Files to modify:** Services only
