## User Experience (File Management)

- [x] CHK001 Are loading states displayed while fetching the file list? [Completeness]
- [x] CHK002 Is visual feedback provided immediately after file upload starts? [Clarity]
- [x] CHK003 Are error messages user-friendly when upload fails (e.g., "File too large" vs "Error 413")? [Clarity]
- [x] CHK004 Is a confirmation modal shown before permanently deleting a file? [Safety]
- [x] CHK005 Does the UI clearly distinguish between "Backups" and "Repositories" tabs? [Clarity]
- [x] CHK006 Is the file list sortable by Date and Name? [Usability]
- [x] CHK007 Are file sizes formatted in human-readable units (KB, MB, GB)? [Usability]
- [x] CHK008 Is the download action easily accessible for each file item? [Accessibility]
- [x] CHK009 Does the upload component support drag-and-drop interactions? [Usability]
- [x] CHK010 Is the "Upload" button disabled or hidden when no category is selected? [Consistency]

## Configuration Flexibility

- [x] CHK011 Can the storage root path be configured to any writable directory on the server? [Flexibility]
- [x] CHK012 Does the system support defining custom directory structures using variables like `{environment}`? [Flexibility]
- [x] CHK013 Does the system support defining custom filename patterns using variables like `{timestamp}`? [Flexibility]
- [ ] CHK014 Are the supported pattern variables (e.g., `{dashboard_name}`) clearly documented in the UI? [Clarity]
- [x] CHK015 Can the configuration be updated without restarting the application? [Usability]
- [ ] CHK016 Is the current resolved path shown as a preview when editing patterns? [Usability]
- [ ] CHK017 Does the system allow reverting configuration to default values? [Recovery]

## Edge Cases & Error Handling

- [x] CHK018 Is the UI behavior defined for an empty file list (zero state)? [Coverage]
- [ ] CHK019 Is the behavior defined when the configured storage path becomes inaccessible? [Resilience]
- [x] CHK020 Are long filenames handled gracefully in the UI (e.g., truncation with tooltip)? [Layout]
- [x] CHK021 Is the behavior defined for uploading a file with a duplicate name? [Conflict Resolution]
