file_exists(), directory_exists(), and ensure_directory() were using
synchronous Path::exists() + is_file()/is_dir() which each perform two
blocking stat(2) syscalls on the Tokio worker thread (0.2-4ms total).
Replace with a single tokio::fs::metadata().await call per method:
- Async: worker thread is never blocked
- 1 syscall instead of 2: metadata() returns file type in one stat(2)
- Proper error propagation for I/O errors (not just silent false)
Remove legacy abstractions that are no longer used after the
100% blob storage model migration (#113):
- IdMappingPort trait from application/ports/outbound.rs
- storage_mediator.rs module (StorageMediator trait + impls)
- StorageMediator impl from PathService
- write_behind_cache.rs (FS-based, incompatible with blob model)
The WriteBehindCachePort trait and Optional fields in services
are preserved for potential future blob-compatible caching.
-968 lines of dead code removed. Build clean, RC=0.
Standardize code formatting across all 173 Rust source files
using rustfmt. No functional changes - purely cosmetic.
This establishes a consistent code style baseline for the
project going forward.
- Remove Serialize/Deserialize from File, Folder, Session, User, Contact entities
- Create contact_persistence_dto.rs for JSONB persistence in infrastructure layer
- Update contact_pg_repository to use persistence DTOs
- Fix dependency on zip crate (downgrade from 7.2.0 to 2.1.0)
- Fix unused variable warnings in main.rs
- Move PathService import from domain to infrastructure
- Add missing fields to CoreServices and RepositoryServices
- Create proper service initialization in main.rs
Clean Architecture improvements:
- Domain layer no longer depends on serde framework
- Persistence concerns isolated to infrastructure layer
- TokenClaims in auth_service.rs is only exception (required for JWT)
