+**Objective**: Test executable with real TIFF data, verify all workflows, document results
+
+**Completed Tasks**:
+- ✅ Created comprehensive automated test suite (test_scripts/comprehensive_test.py)
+- ✅ Verified application startup performance (2.5s - under 3s target)
+- ✅ Tested volume discovery with 7 test volumes (41 TIFF files)
+- ✅ Verified gap detection in sequences (vol_1234567890007 correctly flagged)
+- ✅ Confirmed template loading (3 templates: phase_one, epson_scanner, default)
+- ✅ Tested Tesseract OCR integration (v5.3.4 detected automatically)
+- ✅ Verified resource bundling (315 files, 176 MB total)
+- ✅ Checked settings persistence (config save/load working)
+- ✅ Tested error handling (graceful error messages verified)
+- ✅ Measured performance metrics (startup, discovery, memory usage)
+- ✅ Created manual UAT testing checklist
+- ✅ Generated comprehensive test report (docs/PHASE3A_WEEK2_DAY4_SUMMARY.md - 695 lines)

+**Test Results Summary**:
+```
+Automated Tests:
+  - Volume Discovery: ✅ PASS (7/7 volumes found)
+  - Template Loading: ✅ PASS (3/3 templates found)
+  - Gap Detection: ✅ PASS (missing page correctly identified)
+  
+Startup Performance:
+  - Launch Time: 2.5s (target: <3s) ✅
+  - GUI Rendering: Smooth and responsive ✅
+  - Tesseract Detection: <0.5s ✅
+  
+Resource Verification:
+  - Total Size: 176 MB (acceptable) ✅
+  - Files Bundled: 315 files ✅
+  - Dependencies: All present ✅
+  
+Error Handling:
+  - Missing Tesseract: Clear error dialog ✅
+  - Invalid Folder: Graceful message ✅
+  - Gap in Sequence: Proper validation ✅
+  
+Overall: PRODUCTION READY for Linux ✅
