 ## Component Architecture
@@ -288,6 +306,29 @@ When testing component properties or state, use `FindComponent<T>()`:
 5. **No ViewState**: Store state in private fields or session (ViewState property exists but is syntax-only)
 6. **PostBack Compatibility**: `WebFormsPageBase` provides `IsPostBack`, `PostBack` event, and `__doPostBack()` JS interop bridge
 
+## Migration Rules
+
+These are hard rules for migration work in this repository:
+
+1. **Use the toolkit entry point**: Start project migrations with `migration-toolkit/scripts/bwfc-migrate.ps1` or the `webforms-to-blazor migrate` CLI it forwards to. Do not invent ad hoc regex converters or one-off migration scripts.
+2. **Always target Blazor static SSR**: Generated apps target .NET 10 static server-side rendering. Do not switch the whole app to interactive Blazor Server; only opt into interactive render modes deliberately and per page.
+3. **Trust the shims**: `WebFormsPageBase` preserves `Page.Request`, `Page.Response`, `Page.Session`, `Page.Server`, `Page.Cache`, `Page.ClientScript`, `IsPostBack`, and `ViewState`. Keep migrated code-behind compiling against those shims instead of rewriting to native ASP.NET Core services during Layer 1 or Layer 2 work.
+4. **Preserve BWFC data controls**: Never replace `ListView`, `FormView`, `GridView`, `DataList`, or `Repeater` with manual HTML tables or divs. Fix the generated BWFC markup, templates, item types, or child components instead.
+5. **Register transforms twice**: Every new CLI transform must be registered in both `src/BlazorWebFormsComponents.Cli/Program.cs` DI and `tests/BlazorWebFormsComponents.Cli.Tests/TestHelpers.cs` so the runtime pipeline and isolated test pipeline stay aligned.
+6. **Respect quarantine boundaries**: `PageQuarantineDetector` should quarantine non-essential `Account/`, `Admin/`, `Checkout/`, mobile, payment, or compile-surface blocker pages, but benchmark-critical home, about, contact, product, catalog, and cart flows stay on the runnable path whenever possible.
+
+### Migration Benchmark Progression
+
+The `samples/` folder contains benchmark apps ordered by increasing complexity. Each app exercises more of the CLI and BWFC component surface:
+
+| Sample | Complexity | Key Challenges | Status |
+|--------|-----------|----------------|--------|
+| **WingtipToys** | ★★☆ | E-commerce: products, cart, checkout, identity, EF data binding | **Current focus** — active benchmark runs |
+| **ContosoUniversity** | ★★☆ | University CRUD: master-detail, search, EF migrations | Acceptance tests exist |
+| **DepartmentPortal** | ★★★ | Multi-page portal: advanced data binding, nested controls, complex layouts | Future target — most sophisticated |
+
+Always complete the current benchmark focus before moving to the next. Improvements to the CLI and toolkit should be validated against the current focus app first, then regression-tested against simpler samples.

 ## Migration Shims
 
 The library provides compile-compatibility shims on `WebFormsPageBase` so migrated code-behind compiles unchanged:

+## Migration CLI & Toolkit
+
+### Primary Entry Points
+
+- `src/BlazorWebFormsComponents.Cli/Program.cs` defines the `webforms-to-blazor` CLI entry point and command surface (`migrate`, `convert`, `prescan`, `scan`, `assets extract`, `edmx convert`).
+- `migration-toolkit/scripts/bwfc-migrate.ps1` is the supported migration-toolkit wrapper. It resolves the CLI project and forwards to `migrate` or `prescan` instead of maintaining a separate regex pipeline.
+- The migration-toolkit skill set currently includes `bwfc-migration`, `bwfc-identity-migration`, `bwfc-data-migration`, `migration-standards`, and `l3-performance-optimization`.
+
+### Pipeline Overview
+
+`MigrationPipeline` orchestrates the full migration sequence:
+
+1. `ProjectScaffolder` generates the .NET 10 Blazor static SSR scaffold unless `--skip-scaffold` is used.
+2. `WebConfigTransformer` converts `Web.config` settings into `appsettings.json`.
+3. Ordered markup transforms run first.
+4. Ordered code-behind transforms run second.
+5. `SemanticPatternCatalog` applies higher-level page rewrites.
+6. `PageQuarantineDetector` performs a late compile-surface pass and writes `migration-artifacts/quarantine-manifest.json` when pages must be stubbed.
+7. Static assets, source files, App_Start artifacts, NuGet assets, EDMX output, and redirect annotations are copied or generated.
+
+The CLI currently has **24 core markup transforms plus directive/infrastructure markup passes** and **27 code-behind transforms** wired through `Program.cs`.
+
+### Transform Registration Pattern
+
+When adding a transform:
+
+1. Create the transform class in `src/BlazorWebFormsComponents.Cli/Transforms/`.
+2. Register it in `BuildServiceProvider()` in `src/BlazorWebFormsComponents.Cli/Program.cs`.
+3. Add it to `CreateDefaultPipeline()` in `tests/BlazorWebFormsComponents.Cli.Tests/TestHelpers.cs`.
+4. Add or update focused transform tests and pipeline coverage.
+
+```csharp
+// Program.cs
+services.AddSingleton<IMarkupTransform, MyNewTransform>();
+
+// TestHelpers.cs
+var markupTransforms = new List<IMarkupTransform>
+{
+    new MyNewTransform(),
+};
+```
+
+### Scaffolding System
+
+- `RuntimeDetector` aggregates runtime signal detectors for Entity Framework, session, identity, and `Global.asax` usage.
+- `ProjectScaffolder` generates the project file, `_Imports.razor`, `Components/App.razor`, `Components/Routes.razor`, `Components/Layout/MainLayout.razor`, and launch settings.
+- `ProgramCsEmitter` generates `Program.cs` for .NET 10 static SSR, including `AddRazorComponents()`, `AddBlazorWebFormsComponents()`, `UseStaticFiles()`, and `UseAntiforgery()`.
+- `DatabaseProviderDetector` and `WebConfigTransformer` carry forward database provider and connection-string wiring.
+
+### Quarantine System
+
+- `PageQuarantineDetector` creates build-safe placeholder pages for compile-surface blockers and emits a manifest under `migration-artifacts/quarantine-manifest.json`.
+- Essential benchmark pages (home, about, contact, product, catalog, shopping cart, add-to-cart flows) are exempt from incidental quarantine signals.
+- Quarantined pages keep stub `.razor` and `.razor.cs` files plus the transformed original code-behind as an artifact for later Layer 2 or Layer 3 repair.
+
+### Acceptance Test Suites
+
+Use these suites as the migration quality gate for benchmark apps:
+
+```bash
+# WingtipToys migrated app
+# Set WINGTIPTOYS_BASE_URL first if the app is not on https://localhost:5001
+
+dotnet build src/WingtipToys.AcceptanceTests
+pwsh src/WingtipToys.AcceptanceTests/bin/Debug/net10.0/playwright.ps1 install chromium
+dotnet test src/WingtipToys.AcceptanceTests

+# ContosoUniversity benchmark/original app
+# Set CONTOSO_BASE_URL first if the app is not on http://localhost:44380
