use crate::app_config::MultiAppConfig;
refactor(backend): phase 1 - unified error handling with thiserror Introduce AppError enum to replace Result<T, String> pattern across the codebase, improving error context preservation and type safety. ## Changes ### Core Infrastructure - Add src/error.rs with AppError enum using thiserror - Add thiserror dependency to Cargo.toml - Implement helper functions: io(), json(), toml() for ergonomic error creation - Implement From<PoisonError> for automatic lock error conversion - Implement From<AppError> for String to maintain Tauri command compatibility ### Module Migrations (60% complete) - config.rs: Full migration to AppError - read_json_file, write_json_file, atomic_write - archive_file, copy_file, delete_file - claude_mcp.rs: Full migration to AppError - get_mcp_status, read_mcp_json, upsert_mcp_server - delete_mcp_server, validate_command_in_path - set_mcp_servers_map - codex_config.rs: Full migration to AppError - write_codex_live_atomic with rollback support - read_and_validate_codex_config_text - validate_config_toml - app_config.rs: Partial migration - MultiAppConfig::load, MultiAppConfig::save - store.rs: Partial migration - AppState::save now returns Result<(), AppError> - commands.rs: Minimal changes - Use .map_err(Into::into) for compatibility - mcp.rs: Minimal changes - sync_enabled_to_claude uses Into::into conversion ### Documentation - Add docs/BACKEND_REFACTOR_PLAN.md with detailed refactoring roadmap ## Benefits - Type-safe error handling with preserved error chains - Better error messages with file paths and context - Reduced boilerplate code (118 Result<T, String> instances to migrate) - Automatic error conversion for seamless integration ## Testing - All existing tests pass (4/4) - Compilation successful with no warnings - Build time: 0.61s (no performance regression) ## Remaining Work - claude_plugin.rs (7 functions) - migration.rs, import_export.rs - Add unit tests for error.rs - Complete commands.rs migration after dependent modules Co-authored-by: Claude <claude@anthropic.com>
