-## Sprint Overview
-
-| Field | Value |
-|-------|-------|
-| **Sprint ID** | SPRINT_20260102_001_BE |
-| **Title** | Binary Delta Signatures for Patch Detection |
-| **Working Directory** | `src/BinaryIndex/` |
-| **Duration** | 4-6 weeks |
-| **Dependencies** | None (foundational sprint) |
-| **Advisory Source** | `docs/product-advisories/30-Dec-2025 - Binary Diff Signatures for Patch Detection.md` |
-
-## Problem Statement
-
-Vulnerability scanners today rely on version string comparison to determine if a package is vulnerable. But Linux distributions (RHEL, Debian, Ubuntu, SUSE, Alpine) routinely **backport** security fixes into older versions without bumping the upstream version number.
-
-**Example:** OpenSSL 1.0.1e on RHEL 6 has Heartbleed patched, but upstream says `1.0.1e < 1.0.1g` (the fix version), so scanners flag it as vulnerable. This is **wrong**.
-
-**Solution:** Examine the compiled binary itself. Hash the normalized code of affected functions. Compare against known "patched" and "vulnerable" signatures. This provides **cryptographic proof** the fix is present.
-
-## Technical Design
-
-### Disassembly Engine Selection
-
-**Chosen: B2R2** (fully managed .NET, MIT license)
-
-Rationale:
- **Purely managed (.NET)** - no P/Invoke, runs anywhere .NET runs
- **Multi-format** - ELF, PE, Mach-O (covers Linux, Windows, macOS)
- **Multi-ISA** - x86-64, ARM64 (covers server + Apple Silicon + ARM servers)
- **MIT license** - compatible with AGPL-3.0
- **Lifting capability** - can convert to IR for semantic normalization
- **Performance** - Second fastest after Iced in benchmarks
-
-NuGet: `B2R2.FrontEnd.API` (targets net9.0, compatible with net10.0)
-

+# 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
+| Location | Files |
+|----------|-------|
+| 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 |
+| `IDeltaSignatureRepository.cs` | Added 3 methods + 6 DTOs |
+| `DeltaSignatureRepository.cs` | Implemented aggregation queries |
+| `BinaryIndex.WebService.csproj` | Added Persistence project reference |
+
+### 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)

+# Sprint 20260103_001_FE_preset_pills_patch_map - Filter Presets & Patch Map Explorer
+
+## Topic & Scope
+- Implement two UX polish features identified from product advisory feedback:
+  1. **Filter Preset Pills**: Always-visible filter chips above triage results with URL synchronization for shareable filter states
+  2. **Patch Map Explorer**: Interactive heatmap showing vendor backport coverage across fleet with drill-down to function-level and affected images
+- **Working directory:** `src/Web/StellaOps.Web` (Frontend), `src/BinaryIndex` (Backend)
+
+## Dependencies & Concurrency
+- Extends existing `TriageFilters` model in vuln-explorer feature
+- Requires delta signature data in BinaryIndex for patch coverage queries
+- Can run independently of other sprints
+
+## Documentation Prerequisites
+- `docs/modules/binary-index/architecture.md`
+- `docs/modules/vuln-explorer/architecture.md`

+## Decisions & Risks
+- Decision: Use CSS Grid for heatmap instead of Canvas/SVG for accessibility compliance
+- Decision: Color coding follows severity palette (critical=red, high=orange, medium=yellow, low=blue, safe=green)
+- Risk: Large fleet datasets may require pagination optimization; mitigated with server-side aggregation and limits
