3. Explainer Timeline Component

File: SPRINT_20251229_001_005_FE_explainer_timeline.md Status: ✅ DONE (100%) Module: Lineage / Frontend

What Was Delivered:

• Step-by-step verdict explanation visualization
• Expand/collapse animations for detailed steps

• Confidence contribution indicators
• Dark mode support (CSS variables)
• Full ARIA accessibility (WCAG 2.1 compliant)
• Keyboard navigation support (Enter/Space to expand, Tab navigation)
• Replay button for CGS replay integration

Files Enhanced:

• explainer-timeline.component.ts - Copy logic, markdown generation
• explainer-timeline.component.html - ARIA attributes, semantic HTML
• explainer-timeline.component.scss - List styles, dark mode
• explainer-step.component.html - Keyboard handlers

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)
