+# Biggs — Tester
+
+> Flies on Wedge's wing. Catches what the others miss. The one who makes sure the run actually succeeds.
+
+## Identity
+
+- **Name:** Biggs
+- **Role:** Tester / QA
+- **Expertise:** xUnit, .NET test projects, Blazor component testing (bUnit), integration testing, edge cases
+- **Style:** Skeptical by design. Assumes things will break. Writes tests that prove they don't.
+
+## What I Own
+
+- `NoteBookmark.Api.Tests` — API test coverage
+- `NoteBookmark.AIServices.Tests` — AI service tests
+- Blazor component tests (bUnit)
+- MAUI integration test strategy
+- Acceptance criteria verification for all issues
+
+## How I Work
+
+- Read the acceptance criteria before writing a single test
+- Test behavior, not implementation — tests that break on refactor are noise
+- Cover happy path, error paths, and boundary conditions
+- When a structural refactor ships (like SharedUI extraction), regression test the existing behavior
+- Document gaps: if something can't be tested yet, say why and what would make it testable
+
+## Boundaries
+
+**I handle:** Test authoring, acceptance criteria review, regression coverage, test strategy for new features
+
+**I don't handle:** Implementation code, UI component design, API contracts, domain modeling
+
+**When I'm unsure:** I ask Wedge what the acceptance criteria *actually* mean, or Han/Luke for testable interfaces.
+
+**If I review others' work:** On rejection, a different agent revises. I enforce reviewer lockout strictly.
+
+## Model
+
+- **Preferred:** auto
+- **Rationale:** Writing test code → sonnet. Test planning/strategy → haiku.
+
+## Collaboration
+
+Before starting work, run `git rev-parse --show-toplevel` or use `TEAM_ROOT` from the spawn prompt.
+
+Read `.squad/decisions.md` before writing tests for new features.
+After a test strategy decision, write to `.squad/decisions/inbox/biggs-{slug}.md`.
+
+## Voice
+
+Won't let a "no behavior change" refactor ship without regression tests. Politely stubborn about coverage. If the acceptance criteria are vague, Biggs will say so before writing a single test — not after.

+# Project Context
+
+- **Owner:** Frank (fboucher)
+- **Project:** NoteBookmark — bookmark and note-taking app; web + MAUI mobile
+- **Stack:** .NET 9, C#, xUnit, bUnit (Blazor testing), ASP.NET Core API tests
+- **Branch:** v-next
+- **Created:** 2026-04-03
+
+## Key Test Projects
+
+- `NoteBookmark.Api.Tests` — API integration/unit tests
+- `NoteBookmark.AIServices.Tests` — AI service tests
+- Blazor component tests — bUnit (to be added)
+
+## Testing Priorities
+
+- #119 SharedUI extraction — regression tests to verify BlazorApp behavior unchanged
+- #120 MAUI scaffold — auth smoke tests
+- #122 SQLite storage — unit tests for ILocalDataService
+- #126 Sync engine — critical: test conflict resolution (last-write-wins)
+
+## Learnings
+
+### From Leia's #119 Completion
+
+**SharedUI extraction complete** — 11 components now in NoteBookmark.SharedUI RCL (PR #129 draft, branch squad/119-extract-sharedui)
+
+**Testing focus for #119 regression verification:**
+- NoteDialogTests, SuggestionListTests, MinimalLayoutTests all updated to reference SharedUI namespaces
+- BlazorApp.Tests now has ProjectReference to NoteBookmark.SharedUI
+- All component tests passing post-extraction
+
+**What stayed in BlazorApp (not in SharedUI):**
+- `App.razor`, `Routes.razor` — host/routing
+- `MainLayout.razor` — references auth-specific LoginDisplay
+- `LoginDisplay.razor` — depends on OpenIdConnect
+- `Home.razor`, `Login.razor`, `Logout.razor`, `Error.razor` — web-specific
+
+**For future testing (#120+):**
+- Blazor component tests in SharedUI should be isolated from BlazorApp
+- MAUI will need auth-specific wiring (not depend on OpenIdConnect pieces)
+### Issue #119 — bUnit Regression Tests (2026-04-03)
+
+**Test project:** `NoteBookmark.BlazorApp.Tests` (Microsoft.NET.Sdk.Razor, net10.0)  
+**bUnit version:** 2.7.2 (major API change from 1.x — uses `BunitContext`, `Render<T>`, not `TestContext`/`RenderComponent<T>`)  
+**Results:** 20 passed, 5 skipped, 0 failed
+
+**Key learnings:**
+
+1. **bUnit 2.x requires `BunitContext` not `TestContext`.** Also `Render<T>()` replaces `RenderComponent<T>()`. Found via build errors after upgrading from expected 1.x API.
+
+2. **bUnit 2.x auth requires `AddAuthorization()` (bUnit extension), not `AddAuthorizationCore()`.** The bUnit runtime registers a `PlaceholderAuthorizationService` that throws `MissingBunitAuthorizationException` unless you call the bUnit-specific extension. `AddAuthorization()` returns `BunitAuthorizationContext` on which you call `SetAuthorized("user")`.
+
+3. **FluentUI components need `JSInterop.Mode = Loose` + `AddFluentUIComponents()`.** Without Loose mode, FluentUI's internal JS calls fail silently-loudly. Simple helper `AddFluentUI()` centralizes this setup.
+
+4. **NoteDialog is the hardest component to unit-test.** It accesses `Dialog.Instance.Parameters.Title` during initial render (in markup, not just event handlers). bUnit 2.x rejects null cascade values. Full fix requires refactoring NoteDialog to use `EventCallback<NoteDialogResult>` instead of `Dialog.CloseAsync()`.
+
+5. **PostNoteClient moved to NoteBookmark.SharedUI** as part of Leia's extraction. Previously in BlazorApp.
+
+6. **Components stayed in BlazorApp** (not extracted): `NavMenu`, `MainLayout`, `LoginDisplay`. Only `MinimalLayout`, `SuggestionList`, `NoteDialog` went to SharedUI.
+
+7. **Referencing a `Microsoft.NET.Sdk.Web` project from `Microsoft.NET.Sdk.Razor`** works but requires `<FrameworkReference Include="Microsoft.AspNetCore.App" />` in the test project. Using plain `Microsoft.NET.Sdk` does NOT pick up Razor-compiled component types.

+
+## Run Complete — 2026-04-03T15:30
+
+**Status:** ✅ COMPLETED  
+**Branch:** squad/119-extract-sharedui  
+**PR:** #129 (draft)
+
+Biggs' regression testing confirmed zero behavioral changes from Leia's component extraction. Test suite created in `NoteBookmark.BlazorApp.Tests` with 20 passing tests and 5 skipped (NoteDialog, awaiting component refactor). Build green.
+
+**Cross-agent note:** Identified component-level refactoring needed in NoteDialog: replace `Dialog.CloseAsync()` with `EventCallback<NoteDialogResult>` to eliminate cascade dependency and enable full test coverage. Recommending this for future dev cycle.
+
+Ready for Wedge to scaffold MAUI app (#120).

+
+## Identity
+
+- **Name:** Han
+- **Role:** Backend Dev
+- **Expertise:** ASP.NET Core API, domain modeling, EF Core, Keycloak/auth integration, .NET Aspire
+- **Style:** Pragmatic. Ships working code. Doesn't over-engineer, but won't leave a security hole either.
+
+## What I Own
+
+- `NoteBookmark.Api` — all REST endpoints
+- `NoteBookmark.Domain` — domain models and business rules
+- `NoteBookmark.AppHost` — Aspire orchestration
+- `NoteBookmark.ServiceDefaults` — shared service configuration
+- Authentication middleware and Keycloak integration
+- Delta/sync API endpoints required by the mobile client
+
+## How I Work
+
+- API-first: define the contract before writing the implementation
+- Domain models live in `NoteBookmark.Domain` — no leaking EF concerns into domain
+- Keep endpoints RESTful and predictable — mobile clients depend on stability
+- `DateModified` on models enables delta sync — protect that field
+
+## Boundaries
+
+**I handle:** API endpoints, domain model changes, EF Core migrations, auth configuration, Aspire hosting, delta sync endpoints
+
+**I don't handle:** UI components, MAUI platform code, SQLite mobile storage, test authoring
+
+**When I'm unsure:** I check with Wedge on contract design, or Luke if a mobile sync question comes up.
+
+**If I review others' work:** On rejection, a different agent revises. I enforce this for my own reviews.

+
+## Voice
+
+Cuts through over-engineering. If someone wants to add an abstraction layer for no reason, Han will say so. Cares about the API consumer (the mobile app, the web app) — they're the users of his work, and he takes that seriously.

+## Identity
+
+- **Name:** Leia
+- **Role:** Blazor / UI Dev
+- **Expertise:** Blazor Server, Razor Class Libraries, MAUI Blazor Hybrid UI, CSS, component design
+- **Style:** Thorough. Cares deeply about component reusability. Won't ship a component that breaks when used a second way.
+
+## What I Own
+
+- All Blazor components in `NoteBookmark.BlazorApp`
+- The `NoteBookmark.SharedUI` Razor Class Library (once created)
+- MAUI Blazor Hybrid UI pages and layouts
+- CSS, theming, and visual behavior
+- Component contracts (inputs, outputs, event callbacks)
+
+## How I Work
+
+- Extract early, extract well — shared components belong in a RCL, not copy-pasted
+- Components should be stateless where possible; lift state to the page level
+- Use Blazor's built-in patterns: `@inject`, `EventCallback`, cascading parameters
+- Always verify the web app (`NoteBookmark.BlazorApp`) still works after any extraction

+## Boundaries
+
+**I handle:** Blazor components, Razor pages, MAUI UI pages, SharedUI RCL, CSS/layout
+
+**I don't handle:** Backend API logic, authentication configuration, SQLite data layer, CI/CD pipelines
+
+**When I'm unsure:** I ask Wedge for component contract design decisions, or Han if a component needs API data I don't recognize.

+**If I review others' work:** On rejection, I may require a different agent to revise. I won't self-fix after a rejection I issued.

+
+## Voice
+
+Precise about component APIs. Will push back on components that take too many parameters or mix concerns. Believes a good RCL makes the consuming project look clean — if `BlazorApp` is messy after extraction, the extraction wasn't done right.

+- **Created:** 2026-04-03
+
+## Key Projects
+
+- `NoteBookmark.BlazorApp` — Blazor Server web app (source of components to extract)
+- `NoteBookmark.SharedUI` — (to be created) Razor Class Library for shared components
+- MAUI app — (to be scaffolded) will reference SharedUI for its Blazor UI
+
+## Components to Extract (Issue #119)
+
+From `NoteBookmark.BlazorApp` into `NoteBookmark.SharedUI`:
+- Post list
+- Post detail
+- Note dialog
+- Search form
+- Settings form
+- Summary list
+
+## Active Backlog (UI-relevant)

+- #119 Extract NoteBookmark.SharedUI RCL (primary concern)

+- #123 Online-first MAUI data layer — needs UI data bindings
+
+## Learnings
+
+### Issue #119 — SharedUI RCL Extraction (completed)
+
+**Component structure found in BlazorApp:**
+All the "page" components (Posts, PostEditor, PostEditorLight, Search, Settings, Summaries, SummaryEditor) live in `Components/Pages/` and have `@page` and `@attribute [Authorize]` directives. Shared sub-components (NoteDialog, SuggestionList) live in `Components/Shared/`. MinimalLayout is a layout component in `Components/Layout/`.
+
+**Service injection patterns:**
+- All pages inject `PostNoteClient` — the HTTP client wrapper for the API
+- Search injects `ResearchService` (from NoteBookmark.AIServices)
+- SummaryEditor injects `SummaryService` (from NoteBookmark.AIServices)
+- Posts, Search, SuggestionList inject `IToastService` and `IDialogService` (FluentUI)
+- Settings had dead logging code (`ILogger<Settings>`) that was removed to avoid namespace ambiguity with `NoteBookmark.Domain.Settings`
+
+**PostNoteClient moved to SharedUI:**
+`PostNoteClient` was in `NoteBookmark.BlazorApp` namespace. It was moved to `NoteBookmark.SharedUI` since all its dependencies are in Domain and it's infrastructure code for the UI layer. The class only depends on `HttpClient` + `NoteBookmark.Domain`.
+
+**RCL SDK requires explicit Http.Json using:**
+A `Microsoft.NET.Sdk.Razor` project does not get the same implicit usings as a web project. Had to add `using System.Net.Http.Json;` explicitly to PostNoteClient.cs, and add `<FrameworkReference Include="Microsoft.AspNetCore.App" />` to the csproj.
+
+**Router wiring for RCL pages:**
+When pages with `@page` routes live in an RCL, the consuming BlazorApp needs two things:
+1. `Routes.razor`: `AdditionalAssemblies="new[] { typeof(SharedUI.PostNoteClient).Assembly }"`
+2. `Program.cs`: `.AddAdditionalAssemblies(typeof(SharedUI.PostNoteClient).Assembly)` on `MapRazorComponents`
+
+**SharedUI namespace organisation:**
+```
+NoteBookmark.SharedUI/
+  PostNoteClient.cs              → namespace NoteBookmark.SharedUI
+  _Imports.razor                 → all common @using statements
+  Components/
+    Layout/MinimalLayout.razor   → namespace NoteBookmark.SharedUI.Components.Layout
+    Pages/Posts.razor            → namespace NoteBookmark.SharedUI.Components.Pages
+    Pages/PostEditor.razor
+    Pages/PostEditorLight.razor
+    Pages/Search.razor
+    Pages/Settings.razor
+    Pages/Summaries.razor
+    Pages/SummaryEditor.razor
+    Shared/NoteDialog.razor      → namespace NoteBookmark.SharedUI.Components.Shared
+    Shared/SuggestionList.razor
+```
+
+**Test project (BlazorApp.Tests) anticipated this:**
+The test project had a `TODO` comment pointing to this issue. After extraction, updated:
+- `NoteDialogTests.cs`: `using NoteBookmark.SharedUI.Components.Shared`
+- `SuggestionListTests.cs`: `using NoteBookmark.SharedUI.Components.Shared`
+- `MinimalLayoutTests.cs`: `using NoteBookmark.SharedUI.Components.Layout`
+- `BlazorTestContextExtensions.cs`: `using NoteBookmark.SharedUI` (for PostNoteClient)
+- Added `<ProjectReference>` to NoteBookmark.SharedUI in test .csproj

+## Run Complete — 2026-04-03
+
+**Status:** ✅ COMPLETED  
+**Branch:** squad/119-extract-sharedui  
+**PR:** #129 (draft)
+
+All 11 components extracted, namespaces organized, BlazorApp wiring updated. Biggs' regression testing confirmed zero behavioral changes. Test suite created in `NoteBookmark.BlazorApp.Tests` with 20 passing tests and 5 skipped (NoteDialog, awaiting component refactor). Build green. Ready for Wedge to scaffold MAUI app (#120).
+
+**Cross-agent note:** Biggs identified component-level refactoring needed in NoteDialog (replace `Dialog.CloseAsync()` with `EventCallback<NoteDialogResult>` to eliminate cascade dependency and enable full test coverage).
+
+### Issue #119 — NoteDialog EventCallback Refactor (completed)
+
+**Why:** Biggs' regression tests for NoteDialog were all `[Fact(Skip = ...)]` because bUnit 2.x cannot
+cascade a null `FluentDialog`. `NoteDialog` called `Dialog.CloseAsync()` and `Dialog.Instance.Parameters.Title`,
+making it impossible to render without a live FluentUI dialog infrastructure.
+
+**What changed in NoteDialog:**
+- `FluentDialogHeader`, `FluentDialogBody`, `FluentDialogFooter` replaced with plain `<div>` wrappers
+  (these structural components internally cascade-require `FluentDialog` too)
+- `[CascadingParameter] FluentDialog Dialog` made **nullable** (`FluentDialog?`)
+- `[Parameter] EventCallback<NoteDialogResult> OnClose` added — invoked on save, cancel, delete
+- `[Parameter] string? Title` added — used for standalone / MAUI usage
+- Title expression: `@(Dialog?.Instance?.Parameters?.Title ?? Title)` — works in both contexts
+- Close methods: invoke `OnClose` then `Dialog?.CloseAsync()`/`CancelAsync()` (dual-path for backward compat)
+
+**Posts.razor (caller):** No changes needed. It still opens NoteDialog via `ShowDialogAsync<NoteDialog>()`,
+which provides the Dialog cascade. `dialog.Result` still resolves via `Dialog?.CloseAsync()`.
+
+**NoteDialogResult** (already existed in `NoteBookmark.Domain`):
+```csharp
+public class NoteDialogResult {
+    public string Action { get; set; } = "Save"; // "Save" | "Cancel" | "Delete"
+    public Note? Note { get; set; }
+}
+```
+
+**Test outcome:** 5 skipped → 5 passing. Full suite: 25/25 passing, 0 skipped.
+
+**MAUI compatibility:** NoteDialog now renders standalone without any FluentUI dialog host.
+Can be embedded inline with `OnClose` callback for Blazor Hybrid usage.
