|---|---|---|---|
| M0 | Toolchain & scaffold | ✅ | Gradle 9.3.1 + AGP 9.1.0 wrapper, version catalog, app module, Compose theme, debug APK builds, installs and runs on the `phone` AVD: package `de.softwareapp_hb.filemanager.debug`, `versionCode 1`, `minSdk 26`/`targetSdk 36`, **no `INTERNET` permission**, `lintDebug` clean (one expected `UnusedResources` for the not-yet-used notification icon) |
| M1 | Pure-Kotlin core + JVM tests | ✅ | `core/` is **Android-free**: `StoragePath` (normalised absolute paths that cannot escape the root), `FileEntry` + `FileKind` classification, `MimeTypes`, `NaturalOrder` + `SortSpec` (directories first; `file2` before `file10`), `FileSize`, `NameMatcher` (substring + `*`/`?` glob), `NameAllocator` ("name (1)") and `TransferPlanner` (conflict policies, move-into-self). **44 JVM tests** across 10 classes, all green |
| M2 | Storage layer | ⏳ | `StorageSource` interface with `AllFilesSource` (`MANAGE_EXTERNAL_STORAGE`) and `SafSource` (persisted tree URIs); `VolumeRepository` (`StorageManager`/`StorageVolume`, `StatFs`); permission + all-files-access state machine |
| M2 | Storage layer | ✅ | `StorageSource` with two backends — `AllFilesSource` (`java.io.File` under all-files access) and `SafSource` (`DocumentsContract` over a persisted tree URI), the latter split so the tree↔path mapping (`SafDocumentIds`) is exhaustively testable; `SafGrant` for the picker and its persistence; `VolumeRepository` (`StorageManager`/`StorageVolume` + `StatFs`); `StorageAccess` + `StorageAccessPolicy` for the all-files/SAF decision. **76 JVM tests** total (32 added here) |
| M3 | Operations engine + service | ⏳ | create/rename/copy/move/delete, recursive copy with progress + cancellation, conflict resolution, trash via MediaStore, foreground service + progress notification |
| M4 | Compose UI | ⏳ | browser list/grid, breadcrumb + up navigation, sort/filter sheet, multi-select action bar, details sheet, permission prompts, theme |
| M5 | Analysis, archives, viewers | ⏳ | disk-usage analysis, large-file finder, ZIP/TAR/GZ via Commons Compress, image viewer, text editor |
