* fix: strip [RouteData] from method params instead of replacing with [Parameter]

The [RouteData] → [Parameter] conversion placed [Parameter] on method
parameters, but ParameterAttribute targets properties only (CS0592).
This caused build failures in ProductDetails.razor.cs and
ProductList.razor.cs (Run 15 regression).

Fix: strip [RouteData] entirely and leave a /* TODO */ block comment
directing Layer 2 to promote the value to a [Parameter] property.
Block comments avoid absorbing the closing ) of method signatures.

All 15 L1 tests pass.

Updated the description to clarify the purpose of the library.

…ide (#481)

The [HandlerRoute] attribute and MapBlazorWebFormsHandlers() were eliminated
during the design pivot to Minimal API registration. The actual API uses
MapHandler<T>("/path") in Program.cs, but the documentation still referenced
the old attribute-based pattern throughout.

Changes:
- Remove all [HandlerRoute(...)] decorations from code examples
- Replace MapBlazorWebFormsHandlers() with explicit MapHandler<T>() calls
- Update Quick Start checklist step 5 to reference Program.cs registration
- Add Program.cs registration snippets to all handler examples
- Update troubleshooting table and summary section

… 100%) (#483)

* Tier 2: Property/event gaps + health detection fixes

Health detection:
- Add TypeAliases mapping in ComponentHealthService for components
  whose class name differs from the tracked name (AspNetValidationSummary)
- Fix reference baselines: FileUpload read-only props, TreeView DataSourceID
  on stop type, CustomValidator ServerValidate as Func not EventCallback

Component property/event additions:
- TreeView: 9 new properties (image URLs, tooltips, config stubs)
- BulletedList: 4 properties + 3 events (Click alias, SelectedIndexChanged,
  TextChanged, AutoPostBack, SelectedIndex, SelectedValue, Text)
- SiteMapPath: 2 events (ItemCreated, ItemDataBound) + SiteMapNodeItemEventArgs
- CustomValidator: 2 properties (ClientValidationFunction, IsValid)

Fix existing AutoGenerateDataBindings="False"  "false" in sample + test

Health: 6 components raised to 100% (44  50/59)
Tests: 2,470 pass (22 new)

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Add docs, samples, and integration tests for Tier 2 features

New sample pages:
- TreeView/ImageAndConfig: CollapseImageUrl, ExpandImageUrl, tooltips,
  MaxDataBindDepth, AutoGenerateDataBindings, EnableClientScript
- BulletedList/Selection: Click alias, SelectedIndex, SelectedValue,
  AutoPostBack, Text, SelectedIndexChanged, TextChanged
- SiteMapPath/Events: ItemCreated and ItemDataBound events

Updated sample:
- CustomValidator: ClientValidationFunction and IsValid properties

Documentation updates:
- TreeView.md: Image Customization and Data Binding Config references
- BulletedList.md: Selection properties, Click alias, events
- SiteMapPath.md: Events section, removed ItemDataBound from NOT Supported
- CustomValidator.md: Full documentation (was _TODO_)

Integration tests:
- Added 3 new InlineData entries for new sample pages

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Fix navigation for new sample sub-pages

Add SubPages entries to ComponentCatalog.cs so the sample app
navigation links to the new pages:
- BulletedList: added "Selection" sub-page
- SiteMapPath: added "Events" sub-page
- TreeView: added "ImageAndConfig" sub-page (alphabetical order)

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix: BulletedList Selection demo  separate interactive vs migration stubs

- Click alias demo remains interactive with clear CTA
- New OnClick+SelectedIndex tracking demo shows functional selection
- Migration stub section clearly labeled as markup compatibility only
- Removed misleading SelectedIndexChanged/TextChanged interactive demos
- Updated docs to clarify stubs are accepted but not fired

* feat: wire up SiteMapPath ItemCreated/ItemDataBound events

- Events now fire during OnParametersSetAsync when navigation path changes
- Uses URL change tracking to prevent re-render loops
- ItemCreated fires for each node after path is built
- ItemDataBound fires for each node after ItemCreated
- All 2,470 bUnit tests pass
- All 243 integration tests pass (including SiteMapPath/Events)

* feat: Add docs and sample pages for 6 sub-100% components

Add missing documentation and sample pages to bring 6 components to
100% health score (44 -> 50 components at full health).

Documentation added:
- View.md - MultiView child container component
- Content.md - Master page content region component
- ContentPlaceHolder.md - Master page placeholder component
- MasterPage.md - Master page layout component

Sample pages added:
- RadioButton - standalone radio button with grouping, alignment, events
- NamingContainer - ID scoping with nesting, ctl00 prefix, visibility

Catalog entries added for View, Content, ContentPlaceHolder,
RadioButton, and NamingContainer in ComponentCatalog.cs.
Updated mkdocs.yml navigation.

* fix: Remove duplicate RadioButton sample page causing route conflict

The PR added Components/Pages/ControlSamples/RadioButton/Index.razor but
Pages/ControlSamples/RadioButton/Index.razor already existed with the same
@page route. The ambiguous route crashed the Blazor circuit, cascading
failures to 32 integration tests.

All 243 integration tests now pass.

…rm CI

Code fix providers for BWFC002, BWFC004, BWFC010, BWFC012 hardcoded \r\n
in EndOfLine trivia, causing test failures on Linux CI runners where
source files have \n line endings.

Added SyntaxExtensions.DetectEndOfLine() helper that reads the first
EndOfLineTrivia from the syntax tree, ensuring code fixes match the
document's existing line ending style.

Fixes failing tests in PR #487.

Requested by: Scribe

Changes:
- Orchestration logs for Cyclops (BWFC013/014 analyzers, 6 files, 111 tests) and Beast (architecture guide, 579 lines)
- Session log for analyzer sprint 1 execution
- Merged 10 decision inbox files  decisions.md (BWFC013/014 IDs, analyzer docs, deprecation guidance, ASHX/AXD middleware, RouteData fix, component audit, navigation UX, sample pages, middleware testing)
- Deleted all inbox files after merge
- Appended team updates to Cyclops, Beast, Forge, Jubilee, Rogue history.md files
- PR #487 opened on upstream targeting dev branch

* feat: bundle analyzers in main NuGet + add -Prescan switch to L1 script

Task 1: Added ProjectReference from BlazorWebFormsComponents to
BlazorWebFormsComponents.Analyzers with OutputItemType=Analyzer so
consumers get Roslyn analyzers automatically via the main NuGet package.

Task 2: Added -Prescan switch to bwfc-migrate.ps1 that scans source
.cs files for 9 BWFC analyzer patterns (BWFC001-005, 011-014) and
outputs a JSON summary report without performing any migration.
Includes human-readable breakdown via Write-Host.

Build: 0 errors, 111 analyzer tests pass.

* fix: use DetectEndOfLine() for cross-platform CI compatibility

All 4 code fix providers (BWFC001, BWFC004, BWFC013, BWFC014) used
hardcoded \r\n in SyntaxFactory.EndOfLine(), causing test failures
on Linux CI where source strings use \n.

- Add SyntaxExtensions.DetectEndOfLine() helper that reads line
  endings from the existing syntax tree
- Replace hardcoded \r\n with root.DetectEndOfLine() in all 4
  code fix providers
- Replace foreach+if with LINQ .Where() (CodeQL suggestion)

All 111 analyzer tests pass.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix: use DetectEndOfLine() in MissingParameterAttributeCodeFixProvider

The using directive insertion used SyntaxFactory.CarriageReturnLineFeed
which hardcodes CRLF, failing on Linux CI where source uses LF.

Replace with newRoot.DetectEndOfLine() for cross-platform compatibility.
