| 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 | ✅ | `domain/FileOperations` composes the backend primitives into copy/move/delete/rename with recursive walking, an honest progress total, cooperative cancellation between entries and per-item failure reporting; conflicts are decided through the M1 `TransferPlanner` (`ASK` is surfaced for the UI to resolve). `service/FileOpService` is a `dataSync` foreground service mirroring progress into a notification (`FileOpNotifications` + `text/TextRes`). **99 JVM tests** total (23 added here) |
| M4 | Compose UI | ✅ | `BrowserViewModel` + `BrowserUiState` over `StorageLocation`; browser screen with list/grid, breadcrumbs, in-folder search, a sort/hidden-files/view sheet, multi-select action bar, details sheet, and new-folder/rename/delete/conflict dialogs; a roots view and the "All files access" + SAF-folder prompts; `data/MediaStoreDeleter` routes a delete through the platform's own dialog where it can and falls back to a direct delete; a `FileProvider` backs "open with" and share. **115 JVM tests** total (16 added here) |
| M5 | Analysis, archives, viewers | ⏳ | disk-usage analysis, large-file finder, ZIP/TAR/GZ via Commons Compress, image viewer, text editor |
| M5 | Analysis, archives, viewers | ✅ | `domain/UsageAnalysis` measures recursive folder sizes and finds the largest files, shown by a bar-per-row storage-usage screen; `domain/ArchiveEngine` creates ZIP and extracts ZIP/TAR/TAR.GZ/GZ/BZ2/XZ using `java.util.zip` + Commons Compress (no native code), with **every entry name filtered through `core/ArchivePath` against zip-slip**; a Coil-backed image viewer, thumbnails in the list and grid, a text editor, and compress/extract in the selection bar. **141 JVM tests** total (26 added here) |
| M6 | Release config & Play readiness | ⏳ | R8/minify, optional signing, `.aab`; [PLAY_RELEASE_CHECKLIST](PLAY_RELEASE_CHECKLIST.md) (incl. the **Permissions Declaration Form**), [PRIVACY.md](../PRIVACY.md), README |
| M7 | On-device validation & hardening | ⏳ | AVD + real-device checks, per-operation error boundaries, edge-case fixtures |
| M8 | Localisation groundwork | ⏳ | every user-visible string in `res/values/strings.xml` with real `<plurals>`; `text/` mapping |
