+
+**File management API endpoints and UI for viewing/deleting CSV files from flash memory**
+
+## Performance
+
+- **Duration:** 31 min
+- **Started:** 2026-03-11T23:39:10Z
+- **Completed:** 2026-03-12T00:10:22Z
+- **Tasks:** 4
+- **Files modified:** 5
+
+## Accomplishments
+- Created file management API endpoints (GET /api/files, GET /api/files/<filename>, DELETE /api/files/<filename>)
+- Created files.html template with file list, view modal, and delete functionality
+- Added /files route to Flask app for the file management page
+- Added Files navigation link to all main pages (Dashboard, Settings, Calibration)
+
+## Task Commits
+
+Each task was committed atomically:
+
+1. **task 1: Add file management API endpoints** - API endpoints for list/view/delete
+2. **task 2: Create files.html template** - File management UI
+3. **task 3: Add /files route to Flask app** - Route for file management page
+4. **task 4: Add Files menu item to navigation** - `1b92754` (feat)
+
+**Plan metadata:** `253b8ec` (from prior session), `1b92754` (navigation)
+
+## Files Created/Modified
+- `src/app.py` - Added file management API endpoints and /files route
+- `src/templates/files.html` - File management UI with list, view modal, delete
+- `src/templates/dashboard.html` - Added Files navigation link
+- `src/templates/settings.html` - Added Files navigation link
+- `src/templates/calibration.html` - Added Files navigation link
+
+## Decisions Made
+- Used /myvscada/logger as primary storage path, falling back to src/data/logger
+- File listing returns name, size, and created timestamp for each CSV file
+- Used Bootstrap Icons (bi-folder) for Files navigation
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Issues Encountered
+
+None - all tasks completed successfully.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+- File management foundation complete - ready for data transmission (Plan 02-03)
+- tidEDA export already implemented in Plan 02-02
