+# Phase 5 Plan 03: Integration Verification and Human Sign-Off Summary
+
+**134 tests pass, 22 skipped, 0 fail — single-file EXE (201 MB, 0 loose DLLs) confirmed on clean machine with French locale correct**
+
+## Performance
+
+- **Duration:** ~15 min
+- **Started:** 2026-04-03T14:30:00Z
+- **Completed:** 2026-04-03T15:00:00Z
+- **Tasks:** 2 (1 auto + 1 human-verify)
+- **Files modified:** 0 (verification-only plan)
+
+## Accomplishments
+
+- Full test suite green: 134 pass, 22 skip (known interactive MSAL flows), 0 fail — including all new Phase 5 Plan 01 helpers and locale completeness tests
+- Published SharepointToolbox.exe confirmed as single self-contained file at 201 MB with exactly 0 loose DLL files in ./publish/
+- Human smoke test approved: application launches on clean machine, French diacritics display correctly across all views, all 10 tabs render without crashes
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Run full test suite and verify publish artifact** - `e0e3d55` (chore)
+2. **Task 2: Human smoke test — EXE launch and French locale verification** - Human approved (no code commit)
+
+**Plan metadata:** (this docs commit)
+
+## Files Created/Modified
+
+None — this was a verification-only plan. All prior work was committed in Plans 05-01 and 05-02.
+
+## Decisions Made
+
+None - followed plan as specified. All integration checks passed on first attempt with no fixes required.
+
+## Deviations from Plan
+
+None - plan executed exactly as written. Test suite was green and publish artifact was correct on first run.
+
+## Issues Encountered
+
+None. The FR diacritics test (FrStrings_ContainExpectedDiacritics) passed immediately, confirming Plan 05-02's fixes were complete. Publish produced a single self-contained EXE with no loose DLLs on first attempt.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+Phase 5 (Distribution and Hardening) is complete. All three workstreams integrated successfully:
+- Plan 05-01: helper internals + unit tests
+- Plan 05-02: French locale diacritics + single-file publish config
+- Plan 05-03: full integration gate + human sign-off
+
+The application is ready for distribution. The published EXE is at `./publish/SharepointToolbox.exe`.
