+# Phase 03 Plan 06: Localization — Phase 3 EN and FR Keys Summary
+
+**54 new EN/FR localization keys added across Storage, File Search, and Duplicates tabs with strongly-typed Strings.Designer.cs accessors using dot-to-underscore naming convention**
+
+## Performance
+
+- **Duration:** ~5 min
+- **Started:** 2026-04-02T13:27:00Z
+- **Completed:** 2026-04-02T13:31:33Z
+- **Tasks:** 1
+- **Files modified:** 3
+
+## Accomplishments
+- Added 14 Storage tab keys in both EN (Strings.resx) and FR (Strings.fr.resx): per-library breakdown, subsites, note, generate/open buttons, 7 column headers, 2 radio buttons
+- Added 26 File Search tab keys in both EN and FR: search filters group, extensions/regex/date filters, creator/modifier inputs, library filter, site URL, run/open buttons, 8 column headers, 2 radio buttons
+- Added 14 Duplicates tab keys in both EN and FR: duplicate type radio buttons, comparison criteria group, 5 criteria checkboxes, subsites checkbox, library placeholder, run/open buttons
+- Added 54 static properties to Strings.Designer.cs following established dot-to-underscore naming convention
+- Build verified: 0 errors after all localization changes
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Add Phase 3 keys to Strings.resx, Strings.fr.resx, and Strings.Designer.cs** - `938de30` (feat)
+
+**Plan metadata:** (to be added by final commit)
+
+## Files Created/Modified
+- `SharepointToolbox/Localization/Strings.resx` - 54 new EN data entries for Phase 3 tabs
+- `SharepointToolbox/Localization/Strings.fr.resx` - 54 new FR data entries for Phase 3 tabs
+- `SharepointToolbox/Localization/Strings.Designer.cs` - 54 new static property accessors
+
+## Decisions Made
+None - followed plan as specified. Pre-existing keys verified with git stash/pop workflow to confirm build was clean before changes, and test failures confirmed pre-existing (from export service stubs planned for 03-03/03-05).
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+**Note:** Build had a transient CS1929 error on first invocation (stale compiled artifacts). Second `dotnet build` succeeded with 0 errors. The 9 test failures are pre-existing (export service stubs from plans 03-03/03-05, verified by stashing changes).
+
+## Issues Encountered
+- Transient build error CS1929 on first `dotnet build` invocation (stale .NET temp project files). Resolved automatically on second build.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- All Phase 3 localization keys now present — plans 03-07 and 03-08 can use `TranslationSource.Instance["key"]` XAML bindings without missing-key issues
+- Wave 3: StorageViewModel/View (03-07) is unblocked
+- Wave 4: SearchViewModel + DuplicatesViewModel + Views (03-08) is unblocked
