Claude 1811d42d79 feat: skip local hashing for iCloud assets, use server-computed checksum
Instead of downloading iCloud assets twice (once to hash, once to upload),
skip local hashing for iCloud-only assets and let the server return its
computed SHA1 checksum in the upload response. The mobile app stores this
checksum locally to prevent re-uploads.

Changes:
- Server returns checksum in upload response (created + duplicate)
- iOS native layer tags iCloud-only assets with ICLOUD_ONLY error
- Hash service skips iCloud assets (allowNetworkAccess: false)
- Upload result carries server checksum back to mobile
- Foreground/background upload services store server checksum
- Backup candidates include unhashed assets (onlyHashed: false)

Domain Layer

This directory contains the domain layer of Immich. The domain layer is responsible for the business logic of the app. It includes interfaces for repositories, models, services and utilities. This layer should never depend on anything from the presentation layer or from the infrastructure layer.

Structure

  • Interfaces: These are the interfaces that define the contract for data operations.
  • Models: These are the core data classes that represent the business models.
  • Services: These are the classes that contain the business logic and interact with the repositories.
  • Utils: These are utility classes and functions that provide common functionalities used across the domain layer.

Usage

The domain layer provides services that implement the business logic by consuming repositories through dependency injection. Services are exposed through Riverpod providers in the root providers directory.

// In presentation layer
final userService = ref.watch(userServiceProvider);
final user = await userService.getUser(userId);

The presentation layer should never directly use repositories, but instead interact with the domain layer through services.
