# Sprint Completion Summary - 2026-01-03
|
|
|
|
## SPRINT_20260103_001_FE - Filter Presets & Patch Map Explorer
|
|
|
|
**Status:** ✅ COMPLETE (All 11 tasks)
|
|
|
|
### Overview
|
|
Implemented two UX polish features for the vulnerability explorer:
|
|
1. **Filter Preset Pills** - Always-visible filter chips with URL synchronization for shareable filter states
|
|
2. **Patch Map Explorer** - Interactive heatmap showing vendor backport coverage across fleet
|
|
|
|
### Key Deliverables
|
|
|
|
#### Filter Presets (4 tasks)
|
|
- Extended `TriageFilters` with noise-gating fields (runtimeExecuted, environment, backportProved, semverMismatch)
|
|
- Created 7 standard presets: actionable, prod-runtime, backport-verified, critical-only, needs-review, vex-applied, all-findings
|
|
- `FilterUrlSyncService` for bidirectional URL synchronization
|
|
- `FilterPresetPillsComponent` with horizontal scrolling and copy URL
|
|
|
|
#### Patch Coverage Backend (3 tasks)
|
|
- Added 3 interface methods to `IDeltaSignatureRepository`
|
|
- Implemented PostgreSQL aggregation queries with CTEs
|
|
- Created `PatchCoverageController` with 3 REST endpoints:
|
|
- `GET /api/v1/stats/patch-coverage` - Aggregated coverage by CVE
|
|
- `GET /api/v1/stats/patch-coverage/{cveId}/details` - Function-level breakdown
|
|
- `GET /api/v1/stats/patch-coverage/{cveId}/matches` - Paginated affected images
|
|
|
|
#### Patch Map Frontend (4 tasks)
|
|
- Created `patch-coverage.models.ts` and `patch-coverage.client.ts`
|
|
- Created `PatchMapComponent` with heatmap, details, and matches views
|
|
- Added route `/analyze/patch-map` and navigation entry
|
|
- Linked from `binary-evidence-panel` header
|
|
|
|
### Files Created
|

| Frontend | `filter-preset.models.ts`, `filter-preset-pills.component.ts`, `filter-url-sync.service.ts`, `patch-coverage.models.ts`, `patch-coverage.client.ts`, `patch-map.component.ts` |
|
|
| Backend | `PatchCoverageController.cs` |
|
|
|
|
### Files Modified
|
|
| File | Change |
|
|
|------|--------|
|
|
| `evidence-subgraph.models.ts` | Added noise-gating fields |
|
|
| `app.routes.ts` | Added patch-map route |
|
|
| `navigation.config.ts` | Added Patch Map nav entry |
|
|
| `binary-evidence-panel.component.ts` | Added Patch Map link |
|

|
|
|
|
### Decisions
|
|
- CSS Grid for heatmap (accessibility compliance)
|
|
- Severity-based color coding (critical=red, high=orange, medium=yellow, low=blue, safe=green)
|
|
|
|
### Build Status
|
|
- Backend: ✅ Builds successfully (0 errors)
|
|
- Frontend: ⚠️ Pre-existing errors in other components (not sprint-related)
