A sixth area, Animation System Preparation, was scoped as Phase 3 investigation only. + +**All six Feature issues (#190–#195) have been closed as completed.** The underlying infrastructure – interfaces, service container, event bus, CQRS scaffolding, repository layer, test projects, performance tooling, and documentation – is fully in place. However, **13 Task-level issues (#209–#221) remain formally open**, and a review of the source code reveals that some production call-site migration work (CQRS wiring, EventBus subscriber migration, schema-validation auto-wiring) is still pending before every Phase 2 success criterion can be claimed as fully met. + +The sections below cover each Feature in detail, measure it against the original success criteria, and call out the specific remaining tasks that should be turned into new work items. + +--- + +## Phase 2 Feature Review + +### Feature #190 – Dependency Injection Infrastructure +**Status:** βœ… Closed / Completed (closed 2026-02-19) +**Dependent Tasks:** #209, #212, #213, #214, #215, #216 – All **OPEN** + +#### What Was Delivered +- `ServiceConfiguration` class (`Utility/ServiceConfiguration.cs`) with `AddACATServices()` and `AddACATInfrastructure()` convenience methods +- Ten core manager interfaces extracted and registered in the DI container: + `IActuatorManager`, `IAgentManager`, `ITTSManager`, `IPanelManager`, `IThemeManager`, `IWordPredictionManager`, `ISpellCheckManager`, `IAbbreviationsManager`, `ICommandManager`, `IAutomationEventManager` +- Ten matching factory interfaces and implementations (e.g., `IActuatorManagerFactory`) +- `Context` class enhanced with `ServiceProvider` static property and `GetManager()` method for DI-aware resolution +- `ExtensionInstantiator` verified working with `IServiceProvider` +- All five application entry points (ACATApp, ACATTalk, ACATConfigNext, ACATWatch, ACATConfig) updated to initialise the service container +- 82 DI-specific tests in `ACATCore.Tests.Configuration`; test coverage improved from ~40% to ~72% for DI infrastructure + +#### What Is Still Outstanding +- All task issues (#209–#216) are still open; they need to be formally reviewed and closed (or their remaining sub-scope extracted into new tasks). +- The DI pattern used is **service-locator** (`Context.GetManager()`), not **constructor injection**. Production classes still access managers via `Context.AppXxxMgr` static properties or `XxxManager.Instance`. True constructor injection (passing interface dependencies through constructors) has not been rolled out to existing classes. +- CQRS handlers are registered in DI (Section 3.1 complete) but call sites that *invoke* those handlers still use the old direct singleton pattern (see Feature #194 for details). + +--- + +### Feature #191 – Configuration System Enhancement +**Status:** βœ… Closed / Completed (closed 2026-02-19) +**Dependent Tasks:** #211, #217, #218, #219, #220, #221 – All **OPEN** + +#### What Was Delivered +- **JSON Schema Definition (Task #217):** Six JSON schemas created and stored in `schemas/json/`: + `actuator-settings`, `theme`, `panel-config`, `abbreviations`, `pronunciations`, `animation-config` +- **Schema Validation (Tasks #211 / #218):** `JsonSchemaValidator` class in `Libraries/ACATCore/Configuration/` provides schema loading, caching, and field-level validation with detailed error messages +- **Configuration Hot-Reload (Task #219):** `ConfigurationReloadService` class implements `FileSystemWatcher`-based monitoring with 500 ms debounce; `JsonConfigurationLoader` exposes `EnableHotReload()` / `DisableHotReload()` methods and a `ConfigurationReloaded` event +- **Environment-Specific Configuration (Task #220):** `EnvironmentConfiguration` class supports `Development / Testing / Staging / Production` environments, file layering (`config.Development.json` over `config.json`), and `ACAT_*` environment-variable overrides +- **Configuration Migration Utilities (Task #221):** `ConfigurationVersionManager` class supports semantic-version detection, backup-before-migrate, and pluggable `IConfigurationMigration` handlers + +#### What Is Still Outstanding +- All task issues (#211, #217–#221) are still open; they need formal closure review. +- `JsonSchemaValidator` is **not automatically invoked** by `JsonConfigurationLoader`. Callers must create a validator, load the schema, and call `Validate()` explicitly before loading a configuration file. There is no out-of-the-box enforcement that all configurations are schema-validated on load. Achieving the Phase 2 success criterion ("all configuration files have schema validation") requires either auto-wiring schema validation into `JsonConfigurationLoader` or documenting a clear caller-side convention. +- JSON schemas currently exist for six configuration types. Schemas for additional types (e.g., `AppPreferences`, word-predictor settings, TTS-engine settings, agent configurations) have not been created. +- Automatic migration on load (`ConfigurationVersionManager`) is not wired into `JsonConfigurationLoader`. The caller must check and migrate manually. + +--- + +### Feature #192 – Testing Infrastructure +**Status:** βœ… Closed / Completed (closed 2026-02-19) +**Dependent Tasks:** #196, #197, #222, #223, #224 – All **CLOSED** + +#### What Was Delivered +- MSTest 3.7.0 as the primary test framework across all test projects +- Moq 4.20.72 for mocking; FluentValidation 11.9.0 for configuration validation testing +- `ACATCore.Tests.Shared` library with `BaseTest`, `MockHelper`, `TestDataBuilder`, `TestWorkspace`, `AssertHelper`, `TestDataGenerator` +- Five dedicated test projects: + - `ACATCore.Tests.Configuration` (217 tests) + - `ACATCore.Tests.Architecture` (29 tests) + - `ACATCore.Tests.Integration` (28 tests) + - `ACATCore.Tests.Performance` (45 tests) + - `ACATCore.Tests.Logging` (25 tests) +- Total: **355 tests**, all passing +- CI/CD test automation integrated into `build.yml` / `test.yml` workflows with test-result publishing + +#### Assessment vs. Success Criteria +The testing infrastructure goal ("Test coverage > 60% for core libraries") is **met**.
