Critical: - Replace DISPATCH_TIME_FOREVER with 120s/30s timeouts in ObjC - Log failed asset IDs and error messages in cmdExport/backupTree - Show failed count in export summaries Cleanup: - Remove legacy Bridge methods (ExportAlbumPreviews, ExportAlbumOriginals, BackupAll) - Remove legacy ObjC functions and C stub equivalents - Remove photos.go delegates (package-level pass-throughs) - Remove InterpretExportResult (only used by legacy methods) - Clean up mockBridge fields (rename Fn2 -> Fn) - Fix rc race condition in main_main.go (atomic.Int32) - Remove unused variables (_ = grandTotal, _ = sig) Design: - Fix resolveAlbumID: ListAlbums first (cheap), then direct ID - Unify Cloud type: Asset.Cloud string (was bool) - Extract shared export logic into exportAssets/exportOne - Add worker pool for parallel exports (3 workers when assets >= 4) - Fix backupTree progress bar counter and directory prefix Robustness: - Add nil checks for stringWithUTF8String: in ObjC - Log directory creation errors in ensure_directory (ObjC) Quality: - Add go vet and -race flag to Makefile test target - Add ADR for performSelector cloudIdentifier decision - Add sync comments between Go/ObjC sanitizePathComponent - Add package-level doc comment - Add tests: partial failure, skipped album, album-not-found message

ADR 001: Cloud Status Detection via performSelector
Status
Accepted
Context
We need to detect whether a photo asset is stored locally or in iCloud. Apple's PhotoKit does not expose PHAsset.cloudIdentifier as a public property on macOS. The PHAsset class has this property on iOS but it is undocumented on macOS.
Decision
Use performSelector:@selector(cloudIdentifier) with @try/@catch to detect cloud status. If the selector returns a non-null value, the asset is in iCloud. If it throws an exception, fall back to checking PHAssetResource.isLocallyAvailable (also via performSelector).
Consequences
- This accesses an undocumented Apple API. It may break in any macOS update without warning.
- The
@try/@catchpattern prevents crashes if the selector is removed. - If both checks fail or throw, we default to "local" — this may incorrectly report cloud-only assets as local.
- This approach could cause notarization issues if Apple enforces stricter private API checks in the future.
- No alternative public API exists on macOS for this purpose as of macOS 14.
