Screen

FilesScreen -- sealed interface FilesRoute : NavKey with single route Files (@Serializable data object). Lists uploaded files with upload and delete actions.

ViewModel

FilesViewModel depends on FileRepository and application Context (for content resolver).

State

FilesUiState: files: List<FileObject>, isLoading, isRefreshing, isUploading, error

Operations

Action	Method	Notes
Load	`loadFiles()`	`FileRepository.getFiles()`
Refresh	`refresh()`	Same endpoint, sets `isRefreshing`
Upload	`uploadFile(uri)`	Reads bytes via ContentResolver, gets filename from `OpenableColumns.DISPLAY_NAME`, calls `FileRepository.uploadFile(bytes, filename, mimeType)`
Delete	`deleteFile(fileId)`	`FileRepository.deleteFiles(listOf(fileId))`, removes from local list

Upload Flow

User picks file via SAF (ActivityResultContracts.GetContent)
ContentResolver reads bytes and resolves filename + MIME type
Multipart upload via FilesApi in :core:network
New file prepended to list on success

Image Viewing

FullscreenImageViewer (in feature:chat/components/) provides pinch-to-zoom and pan
Image URLs: /api/files/download/:userId/:file_id for server files
Loaded via Coil AsyncImage with placeholder and error states

Data Layer

FileRepository in :core:data wraps FilesApi from :core:network
API endpoints: GET /api/files (list), POST /api/files (upload, multipart), DELETE /api/files (batch delete)

Spec Notes (not yet implemented)

Multi-select mode for bulk deletion
File preview on tap (non-image files)

File Type Filtering

FileTypeFilterBar — horizontal FilterChip row: All, Images, Documents, Audio, Video
Filters by MIME type prefix in FilesViewModel

Upload Progress

UploadProgressCard — animated card with filename, LinearProgressIndicator, cancel button
Replaces the old fullscreen CircularProgressIndicator overlay
FilesViewModel tracks uploadProgress and uploadFilename in state
Cancel via stored upload Job reference
