+# Phase 5 Plan 02: French Locale Fix and Single-File Publish Summary
+
+**27 French diacritic corrections across all Phase 4 UI string keys, plus conditional win-x64 single-file publish producing one ~200 MB EXE with zero loose DLLs**
+
+## Performance
+
+- **Duration:** ~3 min
+- **Started:** 2026-04-03T11:53:46Z
+- **Completed:** 2026-04-03T11:56:06Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- Fixed all 27 French strings missing diacritics (accents, cedillas) across Transfer, BulkMembers, BulkSites, FolderStruct, Templates, and shared bulk-operation keys
+- Added conditional `<PropertyGroup>` to csproj enabling `dotnet publish -p:PublishSingleFile=true` to produce a single self-contained EXE for win-x64
+- Full test suite remains green: 134 pass, 22 skip (interactive MSAL tests — expected)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **Task 1: Fix French diacritic-missing strings** - `f7829f0` (fix)
+2. **Task 2: Add self-contained single-file publish configuration** - `39517d8` (feat)
+
+## Files Created/Modified
+
+- `SharepointToolbox/Localization/Strings.fr.resx` — 27 string values corrected with proper French diacritics
+- `SharepointToolbox/SharepointToolbox.csproj` — Added conditional PropertyGroup for PublishSingleFile + SelfContained + IncludeNativeLibrariesForSelfExtract
+
+## Decisions Made
+
+- `PublishSingleFile` PropertyGroup uses condition `'$(PublishSingleFile)' == 'true'` so normal builds and test runs are unaffected — no RuntimeIdentifier lock-in during development
+- `IncludeNativeLibrariesForSelfExtract=true` is necessary because PnP.Framework includes native binaries that must be bundled
+- `PublishTrimmed` stays false (pre-established project decision — PnP.Framework and MSAL rely on reflection)
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+Also corrected `bulk.confirm.title` ("Confirmer l'operation" -> "Confirmer l'opération") and `templates.empty` ("Aucun modele enregistre." -> "Aucun modèle enregistré.") and `templates.opt.settings` ("Parametres du site" -> "Paramètres du site") which were not in the plan's numbered list but were clearly broken diacritics in the same file. These fell under Rule 1 (auto-fix bugs) as they were defects in the same file being edited.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- French locale is now complete with proper diacritics across all 4 phases of UI strings
+- Single-file publish is ready: `dotnet publish SharepointToolbox/SharepointToolbox.csproj -c Release -p:PublishSingleFile=true -o ./publish`
+- Two Phase 5 success criteria (French locale + single EXE) now satisfied
+- Remaining Phase 5 work: Plan 01 (tests), Plan 03 (installer/README), Plan 04 (final QA)
