### 4. Node Diff Table Component
**File:** `SPRINT_20251229_001_006_FE_node_diff_table.md`
**Status:** ✅ DONE (100%)
**Module:** Lineage / Frontend

**What Was Delivered:**

**Core Features:**
1. Tabular view of component changes (added/removed/version-changed/license-changed)
2. Row expansion for detailed version/license/CVE info
3. Filter chips (Added, Removed, Changed, Vulnerable Only)
4. Debounced search by component name or PURL (300ms delay)
5. Multi-column sorting (name, version, license, change type)
6. Row selection with bulk actions (export to CSV, create ticket, pin)
7. Stats bar (total, added, removed, changed, vulnerable counts)
8. **Pagination** with page size selector (10/25/50/100 items)
9. API integration (dual mode: direct rows or API fetch via fromDigest/toDigest/tenantId)
10. Loading and error states
11. Dark mode support
12. Full ARIA accessibility

**Enhancements (Post-Implementation):**
13. **Search debouncing** - Prevents excessive re-renders during typing
14. **Copy PURL action** - One-click copy for debugging/tickets
15. **Export to CSV** - Generate CSV file for selected components
16. **Create ticket markdown** - Generate formatted markdown for Jira/GitHub
17. **Keyboard shortcuts** - Ctrl+A to select all, Esc to clear selection
18. **Saved preferences** - Remember page size and sort across sessions (localStorage)

**Testing:**
- Comprehensive unit test suite (450+ lines)
- ~90% code coverage
- Tests for: initialization, API integration, filtering, sorting, expansion, selection, pagination, stats, data transformation

**Files Created:**
- `diff-table.component.ts` - 700+ lines (TypeScript)
- `diff-table.component.html` - 315+ lines (template)
- `diff-table.component.scss` - 710+ lines (styles)
- `models/diff-table.models.ts` - 137 lines (interfaces)
- `diff-table.component.spec.ts` - 450+ lines (unit tests)
