+# Morpheus — History
+
+## Core Context
+
+- **Project:** PowerToys Command Palette — a WinUI 3 extensible command launcher with C++/WinRT SDK and 21 built-in extensions
+- **Role:** ViewModel Dev
+- **Joined:** 2026-03-10T03:10:51.245Z
+
+## Learnings
+
+<!-- Append learnings below -->
+- **SettingsViewModel constructor is called directly** (not via DI) from 5 code-behind files. New optional params must default to `null` to avoid breaking existing call sites.
+- **AOT constraint**: No System.Linq allowed. Use foreach loops for iteration. CompositeFormat is fine on net9.0.
+- **DockMonitorConfig is a mutable class** (not a record). The VM mutates the config object in-place and then calls SaveSettings on the existing SettingsModel — same pattern as DockBandSettingsViewModel.
+- **IMonitorService is registered as singleton** in App.xaml.cs DI container. Resolved via `App.Current.Services.GetService<IMonitorService>()`.
+- **Existing stub pattern**: Trinity may create stub VMs for XAML compilation that Morpheus replaces with real implementations. Check for existing files before creating.
+
+## Session Work (2026-03-10T15:43Z)
+
+**Task:** Build DockMonitorConfigViewModel + update SettingsViewModel  
+**Outcome:** Created full ViewModel with SideOverrideIndex binding (0–4 index mapping to nullable DockSide for "inherit" semantics). Updated SettingsViewModel with IMonitorService injection and RefreshMonitorConfigs(). Both projects build clean. Fixed pre-existing CS0169/SA1512 build warnings that were blocking Oracle's tests.
+
+**Cross-agent awareness:**
+- Trinity added 8 localization strings to support the UI bindings
+- Oracle wrote 27 unit tests validating the DockMonitorConfig.ResolveSide() effective-config fallback logic
+- Neo reviewed for AOT discipline (no LINQ, partial keywords)

+
+### Multi-Monitor Dock Architecture Review (2025-07)
+
+**Architecture:**
+- Multi-monitor dock uses a `DockWindowManager` → per-monitor `DockWindow` pattern
+- `IMonitorService` (ViewModel layer) / `MonitorService` (UI layer via Win32 `EnumDisplayMonitors`)
+- `DockMonitorConfig` provides per-monitor enable/side-override, falls back to global `DockSettings.Side`
+- `DockWindowManager` lives in ShellPage, wired via `ShowHideDockMessage`
+
+**Key file paths:**
+- `src/modules/cmdpal/Microsoft.CmdPal.UI/Dock/DockWindowManager.cs` — multi-monitor orchestrator
+- `src/modules/cmdpal/Microsoft.CmdPal.UI/Services/MonitorService.cs` — Win32 monitor enumeration
+- `src/modules/cmdpal/Microsoft.CmdPal.UI.ViewModels/Models/IMonitorService.cs` — interface
+- `src/modules/cmdpal/Microsoft.CmdPal.UI.ViewModels/Models/MonitorInfo.cs` — record + ScreenRect
+- `src/modules/cmdpal/Microsoft.CmdPal.UI.ViewModels/Settings/DockSettings.cs` — DockMonitorConfig class
+
+**Fixes applied:**
+- Marked `DockWindowManager` as `partial` (CsWinRT1028 AOT warning)
+- Replaced LINQ `.Where().ToList()` with manual loop (AOT safety)
+- Added `List<DockMonitorConfig>` to `JsonSerializationContext` for explicit AOT serialization
+
+**Patterns:**
+- This project is AOT-compiled — avoid LINQ in new code
+- `NativeMethods.txt` declares Win32 APIs for CsWin32 source generator
+- DI registration of `IMonitorService` is in `App.xaml.cs` → `AddUIServices()`
+- `DockWindow` parameterless ctor is required by WinUI; the `MonitorInfo` ctor chains via `: this()`

+### Multi-monitor dock tests (2026-03-10)
+- Test project: `Tests/Microsoft.CmdPal.UI.ViewModels.UnitTests` — MSTest + Moq, references ViewModels project
+- Added `DockMultiMonitorTests.cs` with 27 tests covering `ScreenRect`, `MonitorInfo`, `DockMonitorConfig.ResolveSide`, `DockSettings` defaults, effective-config fallback logic, and `DockBandSettings` resolve pattern
+- `DockWindowManager` is not directly unit-testable (creates `DockWindow` UI objects); tested the pure data logic it depends on instead
+- Pre-existing build errors in ViewModels project (`CS0169` in SettingsViewModel, `SA1512` in DockMonitorConfigViewModel) block full test build — not caused by test code
+- Pattern: `record struct ScreenRect` and `sealed record MonitorInfo` support value equality out of the box — good for assertions
+
+## Session Work (2026-03-10T15:43Z)
+
+**Task:** Write unit tests for multi-monitor dock types  
+**Outcome:** Created DockMultiMonitorTests.cs with 27 tests covering ScreenRect, MonitorInfo, DockMonitorConfig.ResolveSide, DockSettings defaults, and DockBandSettings. Tests compile clean. Identified and reported pre-existing CS0169/SA1512 build errors; Morpheus fixed these. All 27 tests pass.
+
+**Cross-agent awareness:**
+- Morpheus implemented DockMonitorConfig mutable-class pattern and ResolveSide() method; tests validated the effective-config fallback chain
+- Trinity added UI bindings for the 5-item SideOverrideIndex ComboBox (0–4 index mapping)
+- Neo enforced AOT discipline and reviewed test code for LINQ violations
