+    provides: All Phase 1 implementation complete (WPF shell, 8-tab layout, profiles, settings, log panel, MSAL, localization)
+provides:
+  - Confirmed zero-failure test suite (44 pass, 1 skip)
+  - Confirmed zero-warning, zero-error build with -warnaserror
+  - Green light for Phase 2 pending human visual checkpoint approval
+affects:
+  - 02-permissions (blocked until human-verify checkpoint approved)

+# Phase 1 Plan 08: Final Verification Summary
+
+**Full test suite passes (44/44 non-interactive tests green) and build is warning-free under -warnaserror; awaiting human visual checkpoint to confirm WPF shell, localization, and profile UI look and behave correctly**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-04-02T10:41:13Z
+- **Completed:** 2026-04-02T10:46:00Z (Task 1 only — checkpoint pause)
+- **Tasks:** 1 of 2 completed (Task 2 is a human-verify checkpoint)
+- **Files modified:** 1 (.planning/config.json — orchestrator flag)
+
+## Accomplishments
+
+- dotnet build SharepointToolbox.slnx with -warnaserror: 0 warnings, 0 errors
+- dotnet test: 44 passed, 1 skipped (interactive MSAL — expected), 0 failed
+- Build time 1.58s, test run 0.87s — fast baseline confirmed
+
+## Task Commits
+
+Each task committed atomically:
+
+1. **Task 1: Run full test suite and verify zero failures** - `334a5f1` (chore)
+
+**Plan metadata commit:** pending (after human checkpoint approval)
+
+## Files Created/Modified
+
+- `.planning/config.json` - Added `_auto_chain_active: false` flag by orchestrator (minor)
+
+## Decisions Made
+
+- Solution file is `.slnx` (not `.sln`) — all dotnet commands must reference `SharepointToolbox.slnx`
+- 45 tests total: 44 pass, 1 deliberate skip for interactive MSAL browser flow
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None — build and tests clean on first run.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- All automated checks passed
+- Awaiting human visual verification checkpoint (Task 2) to confirm:
+  - WPF shell launches with 8 tabs, log panel, status bar
+  - Language switching (EN/FR) works without restart
+  - Profile management dialog (add/rename/delete) functions correctly
+  - Log panel shows timestamped colored entries
+- Once human approves checkpoint: Phase 1 is complete, ready to begin Phase 2 (Permissions)
