+
+## 1. Architecture Overview
+
+The ACAT animation engine uses a layered architecture designed for backward compatibility. The new engine coexists with the legacy `AnimationPlayer` through an adapter layer.
+
+### Key Design Principles
+
+- **Zero regression**: All existing callers of `PanelAnimationManager` and `UserControlAnimationManager` continue to work unchanged.
+- **Property injection**: `IAnimationService` is injected via a public property, not a constructor parameter, so existing `new PanelAnimationManager(logger)` call sites are not broken.
+- **Graceful fallback**: If the new engine session fails to create, `AnimationPlayerAdapter.TryCreate()` returns `null` and the manager falls back to `AnimationPlayer`.
+- **Strategy pattern**: Scan algorithms (`auto`, `manual`, `step`) are pluggable via `IScanModeStrategy`.
+- **Event bus integration**: State changes are published to `IEventBus` as `AnimationStateChangedEvent`, `AnimationTransitionEvent`, and `AnimationHighlightEvent`.
+
+### Layer Summary
+
+| Layer | Classes | Responsibility |
+|-------|---------|----------------|
+| **Adapter** | `AnimationPlayerAdapter` | Bridges managers to `IAnimationSession` |
+| **Service** | `AnimationService` | Session factory + lifecycle registry |
+| **Session** | `AnimationSession` | Per-panel scan loop, widget highlighting |
+| **Strategy** | `AutoScanStrategy`, `ManualScanStrategy`, `StepScanStrategy` | Scan algorithm selection |
+| **Config** | `AnimationConfig`, `XmlAnimationConfigAdapter` | XML-to-model bridge |
+| **Rendering** | `WinFormsHighlightRenderer` | Visual highlight application |
+| **Events** | `AnimationStateChangedEvent` etc. | Decoupled state change notifications |
+| **Legacy** | `AnimationPlayer`, `AnimationManager` | Preserved for backward compatibility |

+
+## 3. How to Create a New Scan Mode Strategy
+
+Implement `IScanModeStrategy` in `ACAT.Core.AnimationManagement.Strategies`:
+
+```csharp
+using ACAT.Core.AnimationManagement.Configuration;
+using ACAT.Core.AnimationManagement.Interfaces;
+using System.Collections.Generic;
+
+namespace ACAT.Core.AnimationManagement.Strategies
+{
+ ///
+ /// Example: a BCI-specific scan strategy that waits for a neural signal.
+ ///
+ public class BciScanStrategy : IScanModeStrategy
+ {
+ public string Name => "bci";
+
+ public int SelectNext(IReadOnlyList widgets,
+ int currentIndex, IScanContext context)
+ {
+ // BCI: advance only when neural signal is received (handled via HandleInput).
+ // Return currentIndex to hold position until input arrives.
+ if (currentIndex < 0) return 0;
+ return currentIndex; // hold
+ }
+
+ public int SelectPrevious(IReadOnlyList widgets,
+ int currentIndex, IScanContext context)
+ {
+ return currentIndex <= 0 ? 0 : currentIndex - 1;
+ }
+
+ public ScanInputAction HandleInput(ScanInputEvent inputEvent, IScanContext context)
+ {
+ return inputEvent.Type switch
+ {
+ ScanInputType.Switch1Activated => ScanInputAction.Advance,
+ ScanInputType.Switch2Activated => ScanInputAction.Select,
+ _ => ScanInputAction.None
+ };
+ }
+
+ public void OnSequenceStart(IReadOnlyList widgets, IScanContext context) { }
+ public void OnSequenceEnd(IScanContext context) { }
+ }
+}
+```
+
+**Register the strategy** in the DI factory (`DefaultScanStrategyFactory`) or by extending `IScanStrategyFactory`:
+
+```csharp
+public class ExtendedScanStrategyFactory : IScanStrategyFactory
+{
+ public IScanModeStrategy Create(string strategyName)
+ {
+ if (strategyName == "bci") return new BciScanStrategy();
+ return new DefaultScanStrategyFactory().Create(strategyName);
+ }
+}
+```
+
+Then register it in DI:
+```csharp
+services.AddSingleton();
+```
+
+---
+
+## 4. How to Create a Custom Highlight Renderer
+
+Implement `IHighlightRenderer`:
+
+```csharp
+using ACAT.Core.AnimationManagement.Interfaces;
+using ACAT.Core.AnimationManagement.Rendering;
+
+public class DirectXHighlightRenderer : IHighlightRenderer
+{
+ public void Render(string widgetName, HighlightStyle style)
+ {
+ // Use SharpDX to draw a highlight overlay on the widget.
+ }
+
+ public void ClearHighlight(string widgetName)
+ {
+ // Remove overlay for this widget.
+ }
+
+ public void ClearAll()
+ {
+ // Remove all overlays.
+ }
+}
+```
+
+Register it in DI before calling `AddAnimationEngine()`:
+
+```csharp
+services.AddSingleton();
+services.AddAnimationEngine();
+```
+
+> **Note**: `WinFormsHighlightRenderer` is the default production renderer. It accepts callback lambdas and is suitable for most WinForms panels.
+
+---
+
+## 5. How to Add JSON Animation Configuration for a New Panel
+
+The engine supports both XML (legacy) and JSON (new) configuration.
+
+### Option A: JSON file (preferred for new panels)
+
+Create `{PanelName}.animation.json` in the panel's config directory:
+
+```json
+{
+ "panelName": "MyNewPanel",
+ "scanStrategy": "auto",
+ "sequences": [
+ {
+ "name": "Row1",
+ "isFirst": true,
+ "autoStart": true,
+ "iterations": "3",
+ "scanTime": "@ScanTime",
+ "firstPauseTime": "0",
+ "onEnter": "",
+ "onEnd": "",
+ "widgets": [
+ { "name": "Button1", "playBeep": false, "onSelected": "" },
+ { "name": "Button2", "playBeep": false, "onSelected": "" },
+ { "name": "Button3", "playBeep": false, "onSelected": "" }
+ ]
+ },
+ {
+ "name": "Row2",
+ "isFirst": false,
+ "autoStart": true,
+ "iterations": "1",
+ "scanTime": "@ScanTime",
+ "widgets": [
+ { "name": "Button4", "playBeep": true, "onSelected": "switchToPanel(MainPanel)" }
+ ]
+ }
+ ]
+}
+```
+
+Load it via `AnimationConfigProvider`:
+
+```csharp
+var provider = new AnimationConfigProvider();
+var config = provider.LoadForPanel("MyNewPanel", configDirectory);
+```
+
+### Option B: XML (legacy, automatic via XmlAnimationConfigAdapter)
+
+Existing XML panel configs use the `` element. The adapter converts them automatically:
+
+```xml
+
+
+
+
+
+
+
+
+```
+
+The `AnimationPlayerAdapter.TryCreate()` call in `PanelAnimationManager.Start()` handles this automatically by loading the XML node from the config file and passing it to `XmlAnimationConfigAdapter.Convert()`.
+
+### Schema Migration Constraints (C1βC5)
+
+| Constraint | Description | Handling |
+|-----------|-------------|---------|
+| C1 | `Iterations` as `@VarName` runtime reference | Stored as string in `AnimationSequenceConfig.Iterations` |
+| C2 | `ScanTime`/`FirstPauseTime` as variable names | Stored as string in config; resolved at session start |
+| C3 | Wildcard widget names (`Box1/*`, `@SelectedWidget`) | Passed through as-is; expansion is at Start() time |
+| C4 | Per-widget `OnSelected` PCode | Stored in `AnimationWidgetConfig.OnSelected` |
+| C5 | Per-animation `OnEnter`/`OnEnd` PCode | Stored in `AnimationSequenceConfig.OnEnter`/`OnEnd` |
+
+---
+
+## 6. Adapter Layer: PanelAnimationManager Integration
+
+### How the Adapter is Activated
+
+`PanelAnimationManager` and `UserControlAnimationManager` both have an optional `IAnimationService` property:
+
+```csharp
+// Property injection β does not break existing callers
+public IAnimationService AnimationService { get; set; }
+```
+
+When `AnimationService` is non-null, `Start()` calls `AnimationPlayerAdapter.TryCreate()`. If the adapter is created successfully, the new engine runs. If not (exception or null service), the legacy `AnimationPlayer` is used.
+
+### Enabling the New Engine
+
+Set the property after creating the manager:
+
+```csharp
+var animManager = new PanelAnimationManager(LogManager.GetLogger());
+animManager.AnimationService = container.GetService();
+animManager.Init(panelConfigMapEntry);
+```
+
+Or when using DI-constructed objects, inject via the service locator:
+
+```csharp
+// In DialogCommon or ScannerCommon, after creating PanelAnimationManager:
+_animationManager.AnimationService = ServiceLocator.GetService();
+```
+
+### Fallback Behavior
+
+```
+Start() called
+ β
+ βββ AnimationService is null?
+ β βββ Use legacy AnimationPlayer βββββββββββββββββββββββββββββββΊ

+ β
+ βββ TryCreate() returns null (exception during session creation)
+ βββ Use legacy AnimationPlayer ββββββββββββββββββββββββΊ
+```
+
+---
+
+## 7. Migration Guide for Extension Authors
+
+### For New Extensions
+
+Use the new engine directly via `IAnimationService`:
+
+```csharp
+// 1. Resolve from DI
+var animationService = container.GetRequiredService();
+
+// 2. Create a config (from XML or JSON)
+var xmlAdapter = new XmlAnimationConfigAdapter();
+var config = xmlAdapter.Convert(panelName, animationsXmlNode);
+
+// 3. Create and start a session
+var session = animationService.CreateSession(rootWidget, config, "auto");
+session.Start();
+
+// 4. Handle actuator input
+session.Interrupt(); // on switch press
+
+// 5. Clean up
+session.Stop();
+session.Dispose();
+```
+
+### For Existing Extensions
+
+If your extension extends `AnimationManager` directly (like `AnimationSharpManagerV2`):
+
+1. **No immediate changes required** β `AnimationManager` continues to work with `AnimationPlayer`.
+2. **Optional migration**: Add `IAnimationService AnimationService { get; set; }` to your manager and delegate to `AnimationPlayerAdapter.TryCreate()` in your initialization code.
+3. **Future migration**: When ready to fully migrate, replace the `AnimationPlayer` fields with `IAnimationSession` and call `IAnimationService.CreateSession()` directly.
+
+### Interface Changes (None)
+
+All public interfaces (`IAnimationManager`, `IPanelAnimationManager`, `IUserControlAnimationManager`) are **unchanged**. Existing callers are not affected.
+
+---
+
+## 8. BCI Extension Notes
+
+`AnimationSharpManagerV2.cs` (2,885 lines) extends `AnimationManager` with its own scan loop and SharpDX overlay rendering. It continues to function unchanged.
+
+### BCI Migration Roadmap (Future Phase)
+
+The following BCI components could be replaced by the new engine in a future phase:
+
+| BCI Component | New Engine Equivalent | Lines Saved |
+|--------------|----------------------|-------------|
+| Internal scan timer loop (~150 lines) | `SystemScanTimer` + `AutoScanStrategy` | ~150 |
+| Widget highlight logic (~400 lines) | `WinFormsHighlightRenderer` or `DirectXHighlightRenderer` | ~400 |
+| State machine (~300 lines) | `AnimationSession` state machine | ~300 |
+| Switch event routing (~200 lines) | `IScanModeStrategy.HandleInput()` | ~200 |
+| **Total** | | **~1,050 lines** |
+
+The BCI-specific SharpDX rendering (~850 lines) would be preserved as a `DirectXHighlightRenderer` implementation.
+
+---
+
+## 9. Performance Targets
+
+From design spec Β§14 (validated in `AnimationPerformanceBenchmarks.cs`):
+
+| Metric | Target | Test |
+|--------|--------|------|
+| Config load time (5 animations) | β€20ms | BP01 |
+| Config load time (25 animations, BCI worst-case) | β€20ms | BP02 |
+| `AnimationService.CreateSession()` | β€5ms | BP03 |
+| `AnimationSession.Start()` | β€5ms | BP04 |
+| `AnimationSession.Stop()` | β€50ms | BP05 |
+| Service shutdown (10 sessions) | β€100ms | BP06 |
+| 100 adapter lifecycle cycles | β€2s | BP07 |
+
+---
+
+## 10. Testing
+
+### Unit Tests (`ACATCore.Tests.Configuration/AnimationEngineTests.cs`)
+
+Tests T01βT20 cover `TestScanTimer`, `AutoScanStrategy`, `ManualScanStrategy`, `StepScanStrategy`, `AnimationSession`, `XmlAnimationConfigAdapter`, `AnimationConfigProvider`, and DI registration.
+
+### Integration Tests (`ACATCore.Tests.Integration/AnimationIntegrationTests.cs`)
+
+Tests IT01βIT15 cover the full adapter layer:
+- Adapter creation with/without service, with/without XML
+- Start/Stop/Pause/Resume lifecycle
+- Transition between animation sequences
+- Multi-panel scenarios
+- Event bus publication on state changes
+
+### Performance Benchmarks (`ACATCore.Tests.Performance/AnimationPerformanceBenchmarks.cs`)
+
+Tests BP01βBP08 validate that all performance targets from the design spec are met.
+
+### Running the Tests
+
+```bash
+# From src/ directory:
+dotnet test Libraries/ACATCore.Tests.Configuration/ACATCore.Tests.Configuration.csproj --configuration TestOnly
+dotnet test Libraries/ACATCore.Tests.Integration/ACATCore.Tests.Integration.csproj --configuration TestOnly

+//
+// Design:
+// - Created per-panel when IAnimationService is available (injected via

+// - Falls back to legacy AnimationPlayer if session creation fails.
+// - Wraps IAnimationSession lifecycle in Start / Stop / Pause / Resume
