feat(ui): richer diff viewer + surface child roadblocks on parents

- UnifiedDiffParser detects added/deleted/renamed/binary files; diff
  modal shows a file list, binary/empty placeholders, and can diff a
  merged task by commit range after its worktree is gone
- DetailsIslandViewModel flags children needing attention (failed,
  cancelled, awaiting review, or with roadblocks) on the parent
- GitService gains worktree head-commit/range support; planning chain,
  merge orchestration, and session manager tweaks with updated tests
- refresh app/installer/worker icons

+## [Unreleased]
+
+### Fixed
+
+- Review queue is no longer permanently empty: the review virtual list now
+  matches tasks in `WaitingForReview` (it previously matched `Done` + active
+  worktree, a state successful runs never land in).
+- UI ViewModels (`Details`, `Tasks`, `Lists` islands and the shell) now dispose
+  their `Loc.LanguageChanged`, worker-event, and timer subscriptions, fixing
+  long-lived subscription leaks.
+- Stopping a task while the worker is offline no longer throws: `StopAsync`
+  guards on task/running/connection state and handles hub errors.
+
+### Hardening
+
+- Release-readiness audit pass across Worker, Data, UI, MCP, App and Installer
+  (see `docs/open.md` backlog for tracked follow-ups).
+
+## [1.7.0]
+
+- Agent roadblock + run-outcome surfacing in the task detail pane.
+- i18n: localized task-header, task-row and prime-schedule tooltips.
+- CI: dependency-audit and changelog Gitea workflows.
+- Layer A/B/C git merge & conflict-resolution cockpit (multi-worktree
+  batch-merge, inline conflict resolver).

+- Task status flow: Idle | Queued -> Running -> WaitingForReview -> Done | Failed | Cancelled. A task that spawns/has children passes through WaitingForChildren first, then surfaces for review once every child is terminal — this is the single parent model for both planning and improvement parents (planning/improvement *children* themselves go straight to Done, only the parent is reviewed). From review you can approve, reject-rerun (Queued, resumes the session with feedback), reject-park (Idle), or cancel. Approve is the single review+merge action: a childless task merges its own worktree then Done (conflicts keep it in WaitingForReview); a task with children drives the unit merge (parent worktree if any + each Done child in order, with conflict continue/abort). Tasks with no active worktree (sandbox run) approve straight to Done.
 - Worktree state flow: Active -> Merged | Discarded | Kept
 - The queue picker claims tasks by `Status=Queued` (with `BlockedByTaskId IS NULL`); the legacy tag system was removed
 - Interfaces live in an `Interfaces/` subfolder beside their consumers (namespace unchanged)

+# Approve = Merge → Done + Conflict Preview — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Approving a `WaitingForReview` task merges its worktree into the target branch first and only marks the task `Done` on a clean merge; conflicts keep it in review and are surfaced. Add a non-destructive "merges cleanly / conflicts" indicator and a direct single-task Merge button.
+
+**Architecture:** A new `GitService.PreviewMergeAsync` probes mergeability via `git merge-tree --write-tree` (no working-tree mutation). `TaskMergeService` gains `PreviewAsync` and `ApproveAndMergeAsync` (merge first, then delegate the `Done` flip to `ITaskStateService`). `WorkerHub` exposes `PreviewMerge` and a result-returning `ApproveReview(taskId, targetBranch)`. The UI loads merge targets whenever a worktree exists, shows the preview, and reacts to conflict results.
+
+**Tech Stack:** .NET 8, Avalonia, EF Core/SQLite, SignalR, xUnit with real git (`GitRepoFixture`) and real SQLite (`DbFixture`).
+
+**Conventions for the implementer:**
+- Use the **sonnet** model.
+- **Stage files explicitly by path** — never `git add -A` (parallel sessions leave unrelated WIP).
+- Build with `-c Release` (a running Worker locks `Debug` output).
+- Conventional Commit messages: `type(scope): description`.
+- New UI strings use **plain English literals** to match the surrounding merge controls (no `loc:Tr`) — this avoids Localization.Tests parity churn.
+- Ignore anything under `.claude/worktrees/` — those are stale worktrees, not the build tree.

+```csharp

+```
+
+Add these methods inside the `GitService` class (e.g. after `ListConflictedFilesAsync`):
+
+```csharp

+
+## Task 2: TaskMergeService preview + approve-merge orchestration
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Lifecycle/TaskMergeService.cs`
+- Test: `tests/ClaudeDo.Worker.Tests/Services/TaskMergeServiceTests.cs`
+
+`ApproveAndMergeAsync` merges first (reusing `MergeAsync`, `removeWorktree:false`) and only then delegates the `Done` flip to `ITaskStateService.ApproveReviewAsync` (the sole owner of Status writes). Conflicts/blocks return without flipping status. No DI cycle: `TaskStateService` and `PlanningChainCoordinator` do not depend on `TaskMergeService`.
+
+- [ ] **Step 1: Update `BuildService` and add failing tests**
+
+In `tests/ClaudeDo.Worker.Tests/Services/TaskMergeServiceTests.cs`, replace the `BuildService` helper so it also constructs a real `TaskStateService` (existing merge tests still pass — they only inspect the merge service's own broadcaster proxy):
+
+```csharp
+private static (TaskMergeService svc, MergeRecordingClientProxy proxy) BuildService(DbFixture db)
+{
+    var fakeHub = new MergeRecordingHubContext();
+    var broadcaster = new HubBroadcaster(fakeHub);
+    var state = TaskStateServiceBuilder.Build(db.CreateFactory()).State;
+    var svc = new TaskMergeService(
+        db.CreateFactory(),
+        new GitService(),
+        broadcaster,
+        state,
+        NullLogger<TaskMergeService>.Instance);
+    return (svc, fakeHub.Proxy);
+}
+```
+
+Add these tests to the class:
+
+```csharp

+- [ ] **Step 2: Run the tests, verify they fail**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release --filter FullyQualifiedName~TaskMergeServiceTests`
+Expected: build error — `ITaskStateService` ctor arg, `PreviewAsync`, `ApproveAndMergeAsync`, `PreviewClean/PreviewConflict/PreviewUnavailable` do not exist.
+
+- [ ] **Step 3: Implement in TaskMergeService**
+
+In `src/ClaudeDo.Worker/Lifecycle/TaskMergeService.cs`:
+
+Add `using ClaudeDo.Worker.State;` to the usings.
+
+Add the preview-result record beside `MergeTargets`:
+
+```csharp
+public sealed record MergePreviewResult(
+    string Status,
+    IReadOnlyList<string> ConflictFiles,
+    int ChangedFileCount);
+```
+
+Add the status constants beside the existing `StatusMerged` etc.:
+
+```csharp
+public const string PreviewClean       = "clean";
+public const string PreviewConflict    = "conflict";
+public const string PreviewUnavailable = "unavailable";
+```
+
+Add the field and constructor param (inject `ITaskStateService`):
+
+```csharp
+private readonly ITaskStateService _state;
+
+public TaskMergeService(
+    IDbContextFactory<ClaudeDoDbContext> dbFactory,
+    GitService git,
+    HubBroadcaster broadcaster,
+    ITaskStateService state,
+    ILogger<TaskMergeService> logger)
+{
+    _dbFactory = dbFactory;
+    _git = git;
+    _broadcaster = broadcaster;
+    _state = state;
+    _logger = logger;
+}
+```
+
+Add the two methods (e.g. after `GetTargetsAsync`):
+
+```csharp
+public async Task<MergePreviewResult> PreviewAsync(string taskId, string targetBranch, CancellationToken ct)
+{
+    var (_, list, wt) = await LoadMergeContextAsync(taskId, ct);
+
+    if (wt is null || wt.State != WorktreeState.Active)
+        return new MergePreviewResult(PreviewUnavailable, Array.Empty<string>(), 0);
+    if (string.IsNullOrWhiteSpace(list.WorkingDir) || !await _git.IsGitRepoAsync(list.WorkingDir, ct))
+        return new MergePreviewResult(PreviewUnavailable, Array.Empty<string>(), 0);
+
+    var target = string.IsNullOrWhiteSpace(targetBranch)
+        ? await _git.GetCurrentBranchAsync(list.WorkingDir, ct)
+        : targetBranch;
+
+    var preview = await _git.PreviewMergeAsync(list.WorkingDir, target, wt.BranchName, ct);
+    if (!preview.Supported)
+        return new MergePreviewResult(PreviewUnavailable, Array.Empty<string>(), 0);
+    if (!preview.Clean)
+        return new MergePreviewResult(PreviewConflict, preview.ConflictFiles, 0);
+
+    var count = await _git.CountChangedFilesAsync(list.WorkingDir, target, wt.BranchName, ct);
+    return new MergePreviewResult(PreviewClean, Array.Empty<string>(), count);
+}
+
+public async Task<MergeResult> ApproveAndMergeAsync(string taskId, string targetBranch, CancellationToken ct)
+{
+    var (task, list, wt) = await LoadMergeContextAsync(taskId, ct);
+
+    if (task.Status != TaskStatus.WaitingForReview)
+        return Blocked("task is not waiting for review");
+
+    // No worktree to merge (sandbox run, or an improvement parent whose children own
+    // the worktrees) — approve straight to Done.
+    if (wt is null || wt.State != WorktreeState.Active)
+    {
+        var done = await _state.ApproveReviewAsync(taskId, ct);
+        return done.Ok
+            ? new MergeResult(StatusMerged, Array.Empty<string>(), null)
+            : Blocked(done.Reason ?? "approve failed");
+    }
+
+    var target = string.IsNullOrWhiteSpace(targetBranch)
+        ? await _git.GetCurrentBranchAsync(list.WorkingDir, ct)
+        : targetBranch;
+
+    var merge = await MergeAsync(taskId, target, removeWorktree: false, $"Merge {wt.BranchName}", ct);
+    if (merge.Status != StatusMerged)
+        return merge; // conflict or blocked — leave the task in WaitingForReview
+
+    var approve = await _state.ApproveReviewAsync(taskId, ct);
+    return approve.Ok ? merge : Blocked(approve.Reason ?? "approve failed");
+}
+```
+
+- [ ] **Step 4: Run the tests, verify they pass**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release --filter FullyQualifiedName~TaskMergeServiceTests`
+Expected: PASS (all existing + 6 new).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Lifecycle/TaskMergeService.cs tests/ClaudeDo.Worker.Tests/Services/TaskMergeServiceTests.cs
+git commit -m "feat(worker): approve merges worktree before marking task done"
+```
+

+
+## Task 3: WorkerHub — PreviewMerge + result-returning ApproveReview
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Hub/WorkerHub.cs`
+
+This is SignalR wiring (no unit test); verify by building the Worker.
+
+- [ ] **Step 1: Add the DTO**
+
+Beside the existing `MergeResultDto`/`MergeTargetsDto` records (around line 56):
+
+```csharp
+public record MergePreviewDto(string Status, IReadOnlyList<string> ConflictFiles, int ChangedFileCount);
+```
+
+- [ ] **Step 2: Add `PreviewMerge` and replace `ApproveReview`**
+
+Add a `PreviewMerge` method beside `GetMergeTargets`:
+
+```csharp
+public Task<MergePreviewDto> PreviewMerge(string taskId, string targetBranch)
+    => HubGuard(async () =>
+    {
+        var p = await _mergeService.PreviewAsync(taskId, targetBranch ?? "", CancellationToken.None);
+        return new MergePreviewDto(p.Status, p.ConflictFiles, p.ChangedFileCount);
+    });
+```
+
+Replace the existing `ApproveReview` method (currently lines ~383-387, delegating to `_state.ApproveReviewAsync`) with:
+
+```csharp
+public Task<MergeResultDto> ApproveReview(string taskId, string targetBranch)
+    => HubGuard(async () =>
+    {
+        var r = await _mergeService.ApproveAndMergeAsync(taskId, targetBranch ?? "", CancellationToken.None);
+        if (r.Status == TaskMergeService.StatusBlocked)
+            throw new HubException(r.ErrorMessage ?? "approve failed");
+        return new MergeResultDto(r.Status, r.ConflictFiles, r.ErrorMessage);
+    });
+```
+
+(Conflicts are returned, not thrown, so the UI can display the conflicting files; only hard blocks throw.)
+
+- [ ] **Step 3: Build the Worker, verify green**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release`
+Expected: Build succeeded. (DI resolves the new `ITaskStateService` dependency of `TaskMergeService` automatically — it is already registered.)
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Hub/WorkerHub.cs
+git commit -m "feat(worker): expose PreviewMerge hub method and merge-on-approve"
+```
+
+---
+
+## Task 4: UI client + interface + test fakes
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs`
+- Modify: `src/ClaudeDo.Ui/Services/WorkerClient.cs`
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs` (caller at line 648)
+- Modify: `tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs` (`FakeWorkerClient`)
+- Modify: `tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs`
+- Modify: `tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandPlanningTests.cs` (override)
+
+Note: `DetailsIslandViewModel.ApproveReviewAsync` (line 1368) is updated in Task 5, not here — but the interface change forces it to compile, so Task 5 must follow before the Ui project builds. To keep this task self-contained and green on its own, update that call site here too (the conflict-handling logic lands in Task 5).
+
+- [ ] **Step 1: Add the UI DTO**
+
+In `src/ClaudeDo.Ui/Services/WorkerClient.cs`, beside the existing `MergeResultDto`/`MergeTargetsDto` records (lines 521-522):
+
+```csharp
+public record MergePreviewDto(string Status, IReadOnlyList<string> ConflictFiles, int ChangedFileCount);
+```
+
+- [ ] **Step 2: Update the interface**
+
+In `src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs`, replace `Task ApproveReviewAsync(string taskId);` (line 40) with:
+
+```csharp
+Task<MergeResultDto?> ApproveReviewAsync(string taskId, string targetBranch);
+Task<MergePreviewDto?> PreviewMergeAsync(string taskId, string targetBranch);
+Task<MergeResultDto> MergeTaskAsync(string taskId, string targetBranch, bool removeWorktree, string commitMessage);
+```
+
+(`MergeTaskAsync` already exists on the concrete `WorkerClient` — this only adds it to the interface.)
+
+- [ ] **Step 3: Update the concrete client**
+
+In `src/ClaudeDo.Ui/Services/WorkerClient.cs`, replace the existing `ApproveReviewAsync` (line ~389) and add `PreviewMergeAsync`. Mirror the existing `GetMergeTargetsAsync` pattern (it uses the `TryInvokeAsync<T>` helper which returns `null` when disconnected):
+
+```csharp
+public Task<MergeResultDto?> ApproveReviewAsync(string taskId, string targetBranch)
+    => TryInvokeAsync<MergeResultDto>("ApproveReview", taskId, targetBranch);
+
+public Task<MergePreviewDto?> PreviewMergeAsync(string taskId, string targetBranch)
+    => TryInvokeAsync<MergePreviewDto>("PreviewMerge", taskId, targetBranch);
+```
+
+Ensure the existing `public async Task<MergeResultDto> MergeTaskAsync(...)` signature matches the interface exactly (params: `string taskId, string targetBranch, bool removeWorktree, string commitMessage`). Leave its body as-is.
+
+- [ ] **Step 4: Update the two callers**
+
+`src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs` line 648 — the list-level quick approve has no merge-target selector, so it merges into the repo's current branch (empty string resolves server-side):
+
+```csharp
+try { await _worker.ApproveReviewAsync(row.Id, ""); }
+```
+
+`src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs` line 1368 — update to the new signature for now (full conflict handling is added in Task 5):
+
+```csharp
+try { await _worker.ApproveReviewAsync(Task.Id, SelectedMergeTarget ?? ""); }
+```
+
+- [ ] **Step 5: Update the three test fakes**
+
+`tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs` line 53 — replace and add:
+
+```csharp
+public virtual Task<MergeResultDto?> ApproveReviewAsync(string taskId, string targetBranch) => Task.FromResult<MergeResultDto?>(null);
+public virtual Task<MergePreviewDto?> PreviewMergeAsync(string taskId, string targetBranch) => Task.FromResult<MergePreviewDto?>(null);
+public virtual Task<MergeResultDto> MergeTaskAsync(string taskId, string targetBranch, bool removeWorktree, string commitMessage) => Task.FromResult(new MergeResultDto("merged", System.Array.Empty<string>(), null));
+```
+
+`tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs` line 45 (`FakeWorkerClient`) — replace and add:
+
+```csharp
+public Task<MergeResultDto?> ApproveReviewAsync(string taskId, string targetBranch) => Task.FromResult<MergeResultDto?>(null);
+public Task<MergePreviewDto?> PreviewMergeAsync(string taskId, string targetBranch) => Task.FromResult<MergePreviewDto?>(null);
+public Task<MergeResultDto> MergeTaskAsync(string taskId, string targetBranch, bool removeWorktree, string commitMessage) => Task.FromResult(new MergeResultDto("merged", System.Array.Empty<string>(), null));
+```
+
+(Confirm whether `FakeWorkerClient` already implements `MergeTaskAsync`; if so, only change `ApproveReviewAsync` and add `PreviewMergeAsync`. Add `using` for the DTO namespace if needed — same namespace as `IWorkerClient`.)
+
+`tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandPlanningTests.cs` line 77 — update the override signature:
+
+```csharp
+public override Task<MergeResultDto?> ApproveReviewAsync(string taskId, string targetBranch) =>
+    /* keep whatever recording/behavior this override had, now returning Task<MergeResultDto?> */
+    Task.FromResult<MergeResultDto?>(null);
+```
+
+(Preserve any side effect the existing override performed — e.g. recording the call — just change the signature and return type.)
+
+- [ ] **Step 6: Build UI + run both UI-touching test projects**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release --filter FullyQualifiedName~TasksIslandViewModelPlanning`
+Expected: all green.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs src/ClaudeDo.Ui/Services/WorkerClient.cs src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandPlanningTests.cs tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs

+## Task 5: Mergeability presenter + DetailsIslandViewModel wiring
+
+**Files:**
+- Create: `src/ClaudeDo.Ui/ViewModels/Islands/MergePreviewPresenter.cs`
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs`
+- Test: `tests/ClaudeDo.Ui.Tests/ViewModels/MergePreviewPresenterTests.cs` (create)
+
+- [ ] **Step 1: Write the failing presenter tests**
+
+Create `tests/ClaudeDo.Ui.Tests/ViewModels/MergePreviewPresenterTests.cs`:
+
+```csharp
+using ClaudeDo.Ui.Services;
+using ClaudeDo.Ui.ViewModels.Islands;
+
+namespace ClaudeDo.Ui.Tests.ViewModels;
+
+public class MergePreviewPresenterTests
+{
+    [Fact]
+    public void Clean_Plural()
+    {
+        var (text, clean, conflict) = MergePreviewPresenter.Describe(
+            new MergePreviewDto("clean", System.Array.Empty<string>(), 3));
+        Assert.Equal("Merges cleanly · 3 files", text);
+        Assert.True(clean);
+        Assert.False(conflict);
+    }
+
+    [Fact]
+    public void Clean_Singular()
+    {
+        var (text, _, _) = MergePreviewPresenter.Describe(
+            new MergePreviewDto("clean", System.Array.Empty<string>(), 1));
+        Assert.Equal("Merges cleanly · 1 file", text);
+    }
+
+    [Fact]
+    public void Conflict_ListsUpToThree()
+    {
+        var (text, clean, conflict) = MergePreviewPresenter.Describe(
+            new MergePreviewDto("conflict", new[] { "a.cs", "b.cs" }, 0));
+        Assert.Equal("Conflicts in a.cs, b.cs", text);
+        Assert.False(clean);
+        Assert.True(conflict);
+    }
+
+    [Fact]
+    public void Conflict_TruncatesWithMore()
+    {
+        var (text, _, _) = MergePreviewPresenter.Describe(
+            new MergePreviewDto("conflict", new[] { "a", "b", "c", "d", "e" }, 0));
+        Assert.Equal("Conflicts in a, b, c (+2 more)", text);
+    }
+
+    [Fact]
+    public void Unavailable_IsMuted()
+    {
+        var (text, clean, conflict) = MergePreviewPresenter.Describe(
+            new MergePreviewDto("unavailable", System.Array.Empty<string>(), 0));
+        Assert.Equal("Mergeability unknown", text);
+        Assert.False(clean);
+        Assert.False(conflict);
+    }
+
+    [Fact]
+    public void Null_IsEmpty()
+    {
+        var (text, clean, conflict) = MergePreviewPresenter.Describe(null);
+        Assert.Equal("", text);
+        Assert.False(clean);
+        Assert.False(conflict);
+    }
+}
+```
+
+- [ ] **Step 2: Run, verify it fails to compile**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter FullyQualifiedName~MergePreviewPresenterTests`
+Expected: build error — `MergePreviewPresenter` does not exist.
+
+- [ ] **Step 3: Create the presenter**
+
+Create `src/ClaudeDo.Ui/ViewModels/Islands/MergePreviewPresenter.cs`:
+
+```csharp
+using System.Linq;
+using ClaudeDo.Ui.Services;
+
+namespace ClaudeDo.Ui.ViewModels.Islands;
+
+/// Pure mapping from a merge-preview DTO to display text + color flags.
+public static class MergePreviewPresenter
+{
+    public static (string Text, bool IsClean, bool IsConflict) Describe(MergePreviewDto? dto)
+    {
+        if (dto is null) return ("", false, false);
+
+        switch (dto.Status)
+        {
+            case "clean":
+                var unit = dto.ChangedFileCount == 1 ? "file" : "files";
+                return ($"Merges cleanly · {dto.ChangedFileCount} {unit}", true, false);
+
+            case "conflict":
+                var names = string.Join(", ", dto.ConflictFiles.Take(3));
+                var more = dto.ConflictFiles.Count > 3 ? $" (+{dto.ConflictFiles.Count - 3} more)" : "";
+                return ($"Conflicts in {names}{more}", false, true);
+
+            default:
+                return ("Mergeability unknown", false, false);
+        }
+    }
+}
+```
+
+- [ ] **Step 4: Run, verify the presenter tests pass**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter FullyQualifiedName~MergePreviewPresenterTests`
+Expected: PASS (6 tests).
+
+- [ ] **Step 5: Wire the presenter into DetailsIslandViewModel**
+
+In `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs`:
+
+(a) Add observable properties (near the other merge properties, ~line 334):
+
+```csharp
+[ObservableProperty]
+[NotifyPropertyChangedFor(nameof(ShowMergePreviewMuted))]
+private string _mergePreviewText = "";
+
+[ObservableProperty]
+[NotifyPropertyChangedFor(nameof(ShowMergePreviewMuted))]
+private bool _mergeIsClean;
+
+[ObservableProperty]
+[NotifyPropertyChangedFor(nameof(ShowMergePreviewMuted))]
+private bool _mergeIsConflict;
+
+public bool ShowMergePreviewMuted =>
+    !MergeIsClean && !MergeIsConflict && !string.IsNullOrEmpty(MergePreviewText);
+
+public bool ShowSingleMerge =>
+    WorktreePath != null && Task?.IsPlanningParent != true;
+```
+
+(b) Add the refresh method:
+
+```csharp
+private async System.Threading.Tasks.Task RefreshMergePreviewAsync()
+{
+    if (Task is null || WorktreePath is null)
+    {
+        MergePreviewText = ""; MergeIsClean = false; MergeIsConflict = false;
+        return;
+    }
+    // Only probe Active worktrees; terminal states show their label instead.
+    if (WorktreeStateLabel is { } label && label != "Active")
+    {
+        MergePreviewText = label; MergeIsClean = false; MergeIsConflict = false;
+        return;
+    }
+    var dto = await _worker.PreviewMergeAsync(Task.Id, SelectedMergeTarget ?? "");
+    var (text, clean, conflict) = MergePreviewPresenter.Describe(dto);
+    MergePreviewText = text; MergeIsClean = clean; MergeIsConflict = conflict;
+}
+```
+
+(c) Recompute when the merge target changes — add (or extend) the generated partial:
+
+```csharp
+partial void OnSelectedMergeTargetChanged(string? value)
+{
+    _ = RefreshMergePreviewAsync();
+}
+```
+
+(d) Notify `ShowSingleMerge` when the worktree path changes. In the existing `OnWorktreePathChanged` (line ~1141) add:
+
+```csharp
+OnPropertyChanged(nameof(ShowSingleMerge));
+```
+
+(e) Load merge targets for standalone worktree tasks. In `BindAsync`, after the `if (entity.PlanningPhase != None) {...} else {...}` block (~line 814), add:
+
+```csharp
+if (entity.Worktree != null
+    && entity.PlanningPhase == ClaudeDo.Data.Models.PlanningPhase.None
+    && MergeTargetBranches.Count == 0)
+{
+    var targets = await _worker.GetMergeTargetsAsync(row.Id);
+    if (targets != null)
+    {
+        MergeTargetBranches.Clear();
+        foreach (var b in targets.LocalBranches) MergeTargetBranches.Add(b);
+        SelectedMergeTarget = targets.DefaultBranch; // triggers OnSelectedMergeTargetChanged → preview
+    }
+}
+await RefreshMergePreviewAsync();
+```
+
+(f) Replace the body of `ApproveReviewAsync` (line ~1362) to surface conflicts:
+
+```csharp
+[RelayCommand]
+private async System.Threading.Tasks.Task ApproveReviewAsync()
+{
+    if (Task is null || !_worker.IsConnected) return;
+    try
+    {
+        var result = await _worker.ApproveReviewAsync(Task.Id, SelectedMergeTarget ?? "");
+        if (result?.Status == "conflict")
+        {
+            var (text, _, _) = MergePreviewPresenter.Describe(
+                new MergePreviewDto("conflict", result.ConflictFiles, 0));
+            MergePreviewText = text; MergeIsClean = false; MergeIsConflict = true;
+        }
+    }
+    catch { /* stale review action; broadcast reconciles */ }
+}
+```
+
+(g) Add the single-task `MergeCommand` (place near `OpenDiffAsync`):
+
+```csharp
+[RelayCommand]
+private async System.Threading.Tasks.Task MergeAsync()
+{
+    if (Task is null || WorktreePath is null || !_worker.IsConnected) return;
+    try
+    {
+        var result = await _worker.MergeTaskAsync(Task.Id, SelectedMergeTarget ?? "", false, "Merge task");
+        if (result.Status == "conflict")
+        {
+            var (text, _, _) = MergePreviewPresenter.Describe(
+                new MergePreviewDto("conflict", result.ConflictFiles, 0));
+            MergePreviewText = text; MergeIsClean = false; MergeIsConflict = true;
+        }
+        else
+        {
+            await RefreshMergePreviewAsync();
+        }
+    }
+    catch { /* broadcast reconciles */ }
+}
+```
+
+- [ ] **Step 6: Build UI + run the UI tests**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`
+Expected: green. (If `OnSelectedMergeTargetChanged` already exists, merge the new line into it instead of duplicating.)
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/MergePreviewPresenter.cs src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs tests/ClaudeDo.Ui.Tests/ViewModels/MergePreviewPresenterTests.cs
+git commit -m "feat(ui): show mergeability and surface approve conflicts in the work console"
+```
+
+---
+
+## Task 6: WorkConsole — status line + Merge button
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml`
+
+No unit test (XAML); verified by build + manual visual check in Task 7.
+
+- [ ] **Step 1: Add the mergeability status line and the Merge button**
+
+In the `MERGE & WORKTREE` `StackPanel` (starts line 196), insert the status line **between** the merge-target `StackPanel` (ends line 203) and the `<WrapPanel>` (line 204). Three single-line `TextBlock`s, one visible at a time by color:
+
+```xml
+<StackPanel Spacing="0">
+  <TextBlock Classes="meta" Text="{Binding MergePreviewText}" TextWrapping="Wrap"
+             Foreground="{DynamicResource MossBrush}"
+             IsVisible="{Binding MergeIsClean}" />
+  <TextBlock Classes="meta" Text="{Binding MergePreviewText}" TextWrapping="Wrap"
+             Foreground="{DynamicResource BloodBrush}"
+             IsVisible="{Binding MergeIsConflict}" />
+  <TextBlock Classes="meta" Text="{Binding MergePreviewText}" TextWrapping="Wrap"
+             Foreground="{DynamicResource TextMuteBrush}"
+             IsVisible="{Binding ShowMergePreviewMuted}" />
+</StackPanel>
+```
+
+In the `<WrapPanel>` (line 204), add a **Merge** button immediately after the "Open Diff" button (line 206):
+
+```xml
+<Button Classes="btn accent" Content="Merge" Margin="0,0,8,8"
+        Command="{Binding MergeCommand}"
+        IsVisible="{Binding ShowSingleMerge}" />
+```
+
+- [ ] **Step 2: Build UI, verify green**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: Build succeeded (XAML compiles; all bound members exist from Task 5).
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml
+git commit -m "feat(ui): add mergeability indicator and Merge button to work console"
+```
+
+---
+
+## Task 7: Full build, full test, manual verification
+
+**Files:** none (verification only)
+
+- [ ] **Step 1: Build the whole app + worker**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release`
+Expected: both succeed.
+
+- [ ] **Step 2: Run all touched test projects**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release`
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`
+Expected: all green.
+
+- [ ] **Step 3: Manual verification (cannot be automated — no real Claude in tests)**
+
+Start the Worker, then the App. Pick a list whose `WorkingDir` is a real git repo and use a task that already has an Active worktree (or create one).
+
+Verify each acceptance criterion:
+1. **Clean approve:** Open a `WaitingForReview` task whose worktree merges cleanly → the Session tab shows green "Merges cleanly · N files". Click **Approve** → the worktree merges into the target, the task becomes **Done**, and the worktree state becomes **Merged** (check the worktree overview).
+2. **Conflicting approve:** Open a task whose worktree conflicts with the target → the Session tab shows red "Conflicts in …". Click **Approve** → the task stays **WaitingForReview** (NOT Done), the conflict line remains, and the target branch is unchanged.
+3. **Done task preview:** Open a previously-Done task that was never merged (worktree still Active) → the merge/conflict status appears without any tree mutation; the **Merge** button merges it on demand.
+
+Report the result of each check explicitly. If any visual issue appears (colors, layout, missing controls), note it for the user — do not claim the UI works without running it.
+
+---
+
+## Self-review notes
+
+- **Spec coverage:** Approve-merge (Task 2/3/5), conflict-keeps-review (Task 2 test + Task 5 surfacing), non-destructive preview (Task 1/2 + indicator in Task 5/6), real single-task Merge button (Task 5/6), standalone target-loading gap (Task 5e). All spec sections map to a task.
+- **Type consistency:** `MergePreview` (Data) → `MergePreviewResult` (Worker service) → `MergePreviewDto` (hub + UI). Status strings `clean`/`conflict`/`unavailable` and merge statuses `merged`/`conflict`/`blocked` are used consistently across worker, client, presenter, and VM.
+- **No new statuses, no DB migration, no localization keys** (literals match the surrounding controls).
+- **External MCP unchanged:** `ExternalMcpService.ReviewTask` keeps calling `TaskStateService.ApproveReviewAsync` directly (its documented scope excludes merges); that method's signature is unchanged.

+# Refine Task Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. Subagents use the `sonnet` model and stage files explicitly by path (never `git add -A`).
+
+**Goal:** Add a one-click "Refine Task" button to each Idle task card that spawns a headless Claude session which rewrites the task's description and adds subtasks (steps), then updates the task live in the UI.
+
+**Architecture:** A new headless `RefineRunner` (modeled on `PrimeRunner`) runs `claude -p` read-only in the list's working dir, using the globally-registered `claudedo` MCP. Claude calls `update_task` (existing) and a new `add_subtask` tool. The task stays `Idle`; refine only mutates Title/Description/subtasks. UI shows a busy state via new `RefineStarted`/`RefineFinished` SignalR events; content updates arrive via the existing `TaskUpdated` events.
+
+**Tech Stack:** .NET 8, ASP.NET Core + SignalR, EF Core (SQLite), Avalonia 12 (CommunityToolkit.Mvvm), ModelContextProtocol server tools, xUnit.
+
+**Spec:** `docs/superpowers/specs/2026-06-04-refine-task-design.md`
+
+**Build/test reminders:** Build individual csproj with `-c Release` (a running Worker locks Debug). `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release`, `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`, `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release`. Keep `locales/en.json` and `locales/de.json` keys in parity.

+## Task 1: `add_subtask` MCP tool
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/External/ExternalMcpService.cs`
+- Test: `tests/ClaudeDo.Worker.Tests/External/AddSubtaskToolTests.cs`
+
+The `ExternalMcpService` already injects `IDbContextFactory<ClaudeDoDbContext> _dbFactory`, `TaskRepository _tasks`, and `HubBroadcaster _broadcaster`. Reuse them; new up a `SubtaskRepository` from a fresh context (matching the `SetMyDay`/`GetDailyPrepCandidates` pattern in the same file).
+
+- [ ] **Step 1: Write the failing test**
+
+Create `tests/ClaudeDo.Worker.Tests/External/AddSubtaskToolTests.cs`. Follow the existing External tool test setup in that test project (look at a sibling test, e.g. an `ExternalMcpService`/`UpdateTask` test, for the in-memory-real-SQLite fixture + broadcaster fake construction; reuse that exact fixture pattern).
+
+```csharp
+using ClaudeDo.Data.Models;
+using ClaudeDo.Data.Repositories;
+using TaskStatus = ClaudeDo.Data.Models.TaskStatus;
+
+public class AddSubtaskToolTests
+{
+    [Fact]

+        var list = await f.SeedListAsync();
+        var task = await f.SeedTaskAsync(list.Id, status: TaskStatus.Idle);
+
+        await f.Service.AddSubtask(task.Id, "First step", orderNum: null, CancellationToken.None);
+        await f.Service.AddSubtask(task.Id, "Second step", orderNum: null, CancellationToken.None);
+
+        await using var ctx = f.CreateContext();
+        var subs = await new SubtaskRepository(ctx).GetByTaskIdAsync(task.Id);
+        Assert.Equal(new[] { "First step", "Second step" }, subs.Select(s => s.Title));
+        Assert.Equal(new[] { 0, 1 }, subs.Select(s => s.OrderNum));
+        Assert.All(subs, s => Assert.False(s.Completed));
+    }
+
+    [Fact]
+    public async Task AddSubtask_refuses_running_task()
+    {
+        await using var f = new ExternalMcpServiceFixture();
+        var list = await f.SeedListAsync();
+        var task = await f.SeedTaskAsync(list.Id, status: TaskStatus.Running);
+
+        await Assert.ThrowsAsync<InvalidOperationException>(
+            () => f.Service.AddSubtask(task.Id, "x", null, CancellationToken.None));
+    }
+}
+```
+
+> If the test project has no reusable `ExternalMcpServiceFixture`, mirror the construction already used by the nearest existing `ExternalMcpService` test (same ctor args, real SQLite via `IDbContextFactory`, a no-op/recording broadcaster). Do not invent a new pattern.
+
+- [ ] **Step 2: Run the test to verify it fails** (compile error / method missing)
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release --filter AddSubtaskToolTests`

+    - title: {title}
+    - description: {description}
+    - current subtasks (steps):
+    {subtasks}
+
+    What to do:
+    1. If a repository is available, read the relevant code (read-only) to ground your
+       understanding. Do NOT edit, create, or delete any files. Do NOT run commands.
+    2. Rewrite the description so it is clear, specific, and self-contained: what to change,
+       where, and what "done" looks like. Keep scope tight — do not invent adjacent work.
+    3. Call mcp__claudedo__update_task to save the improved title (only if it genuinely
+       helps) and description.
+    4. If the work is clearer as discrete steps, add them as subtasks with
+       mcp__claudedo__add_subtask (one call per step, in order). Only add steps that are
+       not already present in the current subtasks above.
+
+    Use ONLY these tools: mcp__claudedo__get_task, mcp__claudedo__update_task,

+The test project already has a fake/stub for `IClaudeProcess` used by Prime tests — reuse it (recording invocation + returning a configurable success result). Do NOT spawn the real CLI.
+
+```csharp
+public class RefineRunnerTests
+{

+
+> Build the `RefineRunnerFixture`/fakes by copying the Prime test's `IClaudeProcess` stub + real-SQLite `IDbContextFactory` setup and a recording `IRefineBroadcaster`. If a Prime fixture exists, mirror it; otherwise construct inline.

+## Task 4: Worker wiring — broadcaster, hub, DI
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Hub/HubBroadcaster.cs`
+- Modify: `src/ClaudeDo.Worker/Hub/WorkerHub.cs`
+- Modify: `src/ClaudeDo.Worker/Program.cs`
+
+- [ ] **Step 1: Implement events on `HubBroadcaster`**
+
+Add `IRefineBroadcaster` to the class's interface list (`public sealed class HubBroadcaster : ..., IRefineBroadcaster`) and add (mirroring the `Prep*` block):
+
+```csharp
+public Task RefineStarted(string taskId) => _hub.Clients.All.SendAsync("RefineStarted", taskId);
+public Task RefineFinished(string taskId, bool success, string? error) =>
+    _hub.Clients.All.SendAsync("RefineFinished", taskId, success, error);
+
+Task IRefineBroadcaster.RefineStartedAsync(string taskId) => RefineStarted(taskId);
+Task IRefineBroadcaster.RefineFinishedAsync(string taskId, bool success, string? error) =>
+    RefineFinished(taskId, success, error);
+```
+
+Add `using ClaudeDo.Worker.Refine;`.
+
+- [ ] **Step 2: Add `RefineTask` to `WorkerHub`**
+
+`WorkerHub` injects services via its constructor. Add a `private readonly IRefineRunner _refineRunner;` field, add the parameter to the constructor and assign it. Add the method (fire-and-forget; the runner brackets with its own events):
+
+```csharp
+public Task RefineTask(string taskId)
+{
+    _ = _refineRunner.RefineAsync(taskId, CancellationToken.None);
+    return Task.CompletedTask;
+}
+```
+
+Add `using ClaudeDo.Worker.Refine;`.
+
+- [ ] **Step 3: Register DI in `Program.cs`**
+
+Near the Prime registrations:
+
+```csharp
+builder.Services.AddSingleton<IRefineRunner, RefineRunner>();
+builder.Services.AddSingleton<IRefineBroadcaster>(sp => sp.GetRequiredService<HubBroadcaster>());
+```
+
+Add `using ClaudeDo.Worker.Refine;` if needed. (`HubBroadcaster` is already registered as a singleton — confirm and reuse that registration; do not double-register it.)
+
+- [ ] **Step 4: Build the worker**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release`
+Expected: Build succeeded.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Hub/HubBroadcaster.cs src/ClaudeDo.Worker/Hub/WorkerHub.cs src/ClaudeDo.Worker/Program.cs
+git commit -m "feat(refine): wire RefineTask hub method, broadcaster events, and DI"

+
+## Task 5: UI worker client — call + events + fakes
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs`
+- Modify: `src/ClaudeDo.Ui/Services/WorkerClient.cs`
+- Modify: test fakes implementing `IWorkerClient`
+
+- [ ] **Step 1: Extend the interface**
+
+In `IWorkerClient.cs` add (near `RunDailyPrepNowAsync` and the `Prep*` events):
+
+```csharp
+Task RefineTaskAsync(string taskId);
+
+event Action<string>? RefineStartedEvent;
+event Action<string, bool, string?>? RefineFinishedEvent;
+```
+
+- [ ] **Step 2: Implement in `WorkerClient`**
+
+Add the method (mirror `RunDailyPrepNowAsync`):
+
+```csharp
+public Task RefineTaskAsync(string taskId) => _hub.InvokeAsync("RefineTask", taskId);
+```
+
+Declare the events:
+
+```csharp
+public event Action<string>? RefineStartedEvent;
+public event Action<string, bool, string?>? RefineFinishedEvent;
+```
+
+Subscribe in the constructor (mirror the `Prep*` subscriptions block):
+
+```csharp
+_hub.On<string>("RefineStarted", id =>
+    Dispatcher.UIThread.Post(() => RefineStartedEvent?.Invoke(id)));
+_hub.On<string, bool, string?>("RefineFinished", (id, ok, err) =>
+    Dispatcher.UIThread.Post(() => RefineFinishedEvent?.Invoke(id, ok, err)));
+```
+
+- [ ] **Step 3: Update test fakes**
+
+Find every hand-rolled `IWorkerClient` implementation (search the test projects) and add `RefineTaskAsync` (return `Task.CompletedTask`) plus the two events (`= delegate {}` or `add{}remove{}` no-ops as the fake convention dictates). Build each affected test project.
+
+- [ ] **Step 4: Build UI + test projects**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Then build the UI test project(s). Expected: Build succeeded.

+<StreamGeometry x:Key="Icon.Refine">M3,5 L11,5 M3,9 L9,9 M3,13 L7,13 M19,1.8 L19.7,3.9 L21.7,4.6 L19.7,5.3 L19,7.4 L18.3,5.3 L16.3,4.6 L18.3,3.9 Z M18,10.5 L12.2,16.3 M16.6,9.1 L19.4,11.9 M12.2,16.3 L11,18.5 L13.2,17.5 Z</StreamGeometry>
+```
+
+- [ ] **Step 2: Add `IsRefining`/`CanRefine` to `TaskRowViewModel`**
+
+Add the observable property (with the other `[ObservableProperty]` fields):
+
+```csharp
+[ObservableProperty] private bool _isRefining;
+```
+
+Add a computed gate (refine is only offered for Idle, non-parent tasks). Place near other `Can*` getters:
+
+```csharp
+public bool CanRefine => Status == TaskStatus.Idle && PlanningPhase == PlanningPhase.None && !IsRefining;
+```
+
+If `Status`/`PlanningPhase`/`IsRefining` are `[ObservableProperty]`, raise `CanRefine` change notifications via partial `On<Prop>Changed` hooks:
+
+```csharp
+partial void OnStatusChanged(TaskStatus value) => OnPropertyChanged(nameof(CanRefine));
+partial void OnPlanningPhaseChanged(PlanningPhase value) => OnPropertyChanged(nameof(CanRefine));
+partial void OnIsRefiningChanged(bool value) => OnPropertyChanged(nameof(CanRefine));
+```
+
+> If `On...Changed` partials already exist for `Status`/`PlanningPhase`, add the `OnPropertyChanged(nameof(CanRefine))` line inside them instead of redeclaring.
+
+- [ ] **Step 3: Add `RefineTaskCommand` + event wiring to `TasksIslandViewModel`**
+
+Add the command (mirror an existing per-row command like `ToggleStarCommand`, which takes a `TaskRowViewModel`):
+
+```csharp
+[RelayCommand]
+private async Task RefineTask(TaskRowViewModel row)
+{
+    if (row is null || !row.CanRefine) return;
+    row.IsRefining = true;
+    try { await _worker.RefineTaskAsync(row.Id); }
+    catch { row.IsRefining = false; }
+}
+```
+
+> Use the same injected worker-client field name this VM already uses (e.g. `_worker`/`_client`). Match it.
+
+Subscribe to the refine events where the VM wires other worker events (where `OnWorkerTaskUpdated` is subscribed). Add handlers that flip the row flag:
+
+```csharp
+private void OnRefineStarted(string taskId)
+{
+    var row = Items.FirstOrDefault(r => r.Id == taskId);
+    if (row is not null) row.IsRefining = true;
+}
+
+private void OnRefineFinished(string taskId, bool ok, string? error)
+{
+    var row = Items.FirstOrDefault(r => r.Id == taskId);
+    if (row is not null) row.IsRefining = false;
+}
+```
+
+Wire them next to the existing subscriptions (and unsubscribe in the same place the VM unsubscribes others, if it does):
+
+```csharp
+_worker.RefineStartedEvent += OnRefineStarted;
+_worker.RefineFinishedEvent += OnRefineFinished;
+```
+
+(Content changes—new description/subtasks—arrive through the existing `TaskUpdated` → `OnWorkerTaskUpdated` path; no extra work needed.)
+
+- [ ] **Step 4: Add the button to `TaskRowView.axaml`**
+
+Mirror the star button (`Grid.Column="5"` area). Add a refine `icon-btn` (e.g. as a new column or beside the star) bound to the parent ItemsControl's command, passing the row as parameter. Use the `plan-icon` stroked `Path` inside a `Viewbox` (matching the Plan-day button), gate visibility on `CanRefine`, and disable/spin on `IsRefining`:
+
+```xml
+<Button Classes="icon-btn refine-btn"
+        IsVisible="{Binding CanRefine}"
+        Command="{Binding $parent[ItemsControl].((vm:TasksIslandViewModel)DataContext).RefineTaskCommand}"
+        CommandParameter="{Binding}"
+        ToolTip.Tip="{loc:Tr tasks.refineTip}">
+  <Viewbox Width="16" Height="16">
+    <Path Classes="plan-icon" Data="{StaticResource Icon.Refine}"/>
+  </Viewbox>
+</Button>
+```
+
+> Match the column layout already in `TaskRowView.axaml`. If a new grid column is needed, widen `ColumnDefinitions` accordingly and place the refine button left of the star (`Grid.Column`). Keep the existing `vm:` / `loc:` xmlns aliases the file already declares.
+
+Optionally show a spinning/dimmed state while `IsRefining` (e.g. a style `Selector="Button.refine-btn:disabled"` or bind opacity to `IsRefining`). Keep it simple; a disabled look is enough.
+
+- [ ] **Step 5: Add localization keys**
+
+Add to both `locales/en.json` and `locales/de.json` under the `tasks` group (keys must stay in parity):
+
+- en: `"tasks.refineTip": "Refine this task with Claude"`
+- de: `"tasks.refineTip": "Aufgabe mit Claude verfeinern"`
+
+> Match the file's actual key structure (flat `"tasks.x"` vs nested `tasks: { x }`)—look at an existing `tasks.*` tooltip key (e.g. the plan-day tip) and follow it exactly.
+
+- [ ] **Step 6: Build UI**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Then run the Localization parity tests: `dotnet test tests/ClaudeDo.Localization.Tests/ClaudeDo.Localization.Tests.csproj -c Release`
+Expected: Build succeeded; locale parity passes.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Design/IslandStyles.axaml src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs locales/en.json locales/de.json
+git commit -m "feat(ui): add Refine button, icon, and command to task card"
+```
+
+---
+
+## Task 7: Full build + test sweep, manual smoke
+
+- [ ] **Step 1: Build all main projects**
+
+```bash
+dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release
+dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release
+```
+Expected: Build succeeded for both.
+
+- [ ] **Step 2: Run the worker + UI test suites**
+
+```bash
+dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release
+dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release
+dotnet test tests/ClaudeDo.Localization.Tests/ClaudeDo.Localization.Tests.csproj -c Release
+```
+Expected: all green.
+
+- [ ] **Step 3: Manual smoke (visual + real CLI — flag to user)**
+
+Cannot be automated (no real-Claude in tests). Verify by hand: start Worker + UI, on an Idle task click the refine icon → button shows busy → after the run the description improves and steps appear in the Steps card → task stays Idle. Confirm the refine icon is hidden for Queued/Running/Done tasks and for planning parents. **Report this as a visual-verification gap for the user to confirm.**
+
+---
+
+## Notes on parallelism / execution
+
+- Tasks 1–4 are backend and largely sequential (4 depends on 3). Tasks 1 and 2 are independent and could be done first in either order.
+- Tasks 5–6 (UI) depend on Task 4's hub/event contract.
+- Per project convention: subagents use `sonnet`, stage files by explicit path, and do NOT run git/build inside parallel agents — the orchestrator builds, tests, and commits after each task.

+# Task Detail Redesign — Component Build Prompts
+
+Three isolated build tasks (one per component). Each runs in its own worktree off
+`main`, with the project CLAUDE.md auto-loaded. Full design context lives in
+`docs/superpowers/specs/2026-06-04-task-detail-redesign-design.md` — every task
+must read it first.
+
+Shared rules (all three):
+- Build a **standalone** `UserControl` + dedicated `ViewModel` that renders fully
+  in the Avalonia previewer via **design-time sample data** (parameterless ctor
+  populating realistic values). Do **not** bind to `DetailsIslandViewModel`.
+- New files under `src/ClaudeDo.Ui/Views/Islands/Detail/` and
+  `src/ClaudeDo.Ui/ViewModels/Islands/Detail/`.
+- Use **only** tokens from `Design/Tokens.axaml` and classes from
+  `Design/IslandStyles.axaml`. No inline hex, no magic numbers where a token
+  exists. `PathIcon` fills geometry — stroke-only art is invisible.
+- Compiled bindings (`x:DataType`). MVVM via CommunityToolkit
+  (`[ObservableProperty]`, `[RelayCommand]`); VM inherits `ViewModelBase`.
+- **Do NOT modify** `DetailsIslandView.axaml`, `DetailsIslandViewModel.cs`,
+  `AgentStripView`, `SessionTerminalView`, or `TaskRunner.cs`.
+- Verify: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj -c Release` is green.
+  Stage files explicitly by path (never `git add -A`). Commit with a conventional
+  message.

+# Git Merge/Review — Shared Foundation + Layer A Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the shared worker conflict contract (so parallel Layer B/C sessions branch from frozen interfaces) and rework the Git tab into a single Approve+merge cockpit.
+
+**Architecture:** Phase 0 adds the conflict-resolution contract to `IWorkerClient`/`WorkerClient` (real `_hub.InvokeAsync` bodies — the worker hub methods are implemented later by Layer C; calls simply fail at runtime until then) plus client-side DTOs and test-fake updates, then commits + pushes so B and C branch from it. Phase A reworks `WorkConsole.axaml`'s Git tab and routes single-task merge/approve conflicts into a `RequestConflictResolution` seam (wired to Layer C's resolver by the integrator at merge time).
+
+**Tech Stack:** .NET 8, Avalonia 12 (Fluent), CommunityToolkit.Mvvm, SignalR, xUnit. Build individual csproj with `-c Release` (`.slnx` needs .NET 9; a running Worker locks `Debug`).
+
+**Reference spec:** `docs/superpowers/specs/2026-06-05-git-merge-review-rework-design.md`
+
+**Note on the canonical diff renderer:** the unified diff model/control already exists — `DiffFileViewModel`/`DiffLineViewModel`/`UnifiedDiffParser` (in `src/ClaudeDo.Ui/ViewModels/Modals/`) rendered by `DiffLinesView` (`src/ClaudeDo.Ui/Views/Controls/DiffLinesView.axaml`). `DiffModalView` and `PlanningDiffView` already use it. So "consolidate diff renderers" for this scope is just verifying that (Task A.3); migrating `WorktreeModalView`'s bespoke diff onto `DiffLinesView` is Layer B's job.
+
+---
+
+## File Structure
+
+**Phase 0 (foundation — pushed before B/C branch):**
+- Modify `src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs` — 5 new method signatures.
+- Modify `src/ClaudeDo.Ui/Services/WorkerClient.cs` — 5 `InvokeAsync` bodies + 3 new DTO records.
+- Modify `tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs` — 5 new `virtual` no-op methods.
+- Modify `tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs` — 5 new methods on `FakeWorkerClient`.
+
+**Phase A (Layer A — this session, after foundation commit):**
+- Modify `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs` — `RequestConflictResolution` seam; route Approve/Merge conflicts into it.
+- Modify `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml` — fuse REVIEW + MERGE sections into one cockpit block.
+- Test: `tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandPlanningTests.cs` (or a sibling test file in the same folder).
+
+---
+
+## Phase 0 — Shared Foundation
+
+### Task 0.1: Add the conflict contract (interface + client + DTOs)
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs`
+- Modify: `src/ClaudeDo.Ui/Services/WorkerClient.cs`
+
+- [ ] **Step 1: Add the 5 method signatures to `IWorkerClient`**
+
+In `src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs`, after the existing
+`Task CancelReviewAsync(string taskId);` line (line 45), add:
+
+```csharp
+    // ── Conflict resolution (worker hub side implemented by Layer C) ──
+    Task<MergeResultDto> StartConflictMergeAsync(string taskId, string targetBranch);
+    Task<MergeConflictsDto> GetMergeConflictsAsync(string taskId);
+    Task WriteConflictResolutionAsync(string taskId, string path, string resolvedContent);
+    Task<MergeResultDto> ContinueMergeAsync(string taskId);
+    Task AbortMergeAsync(string taskId);
+```
+
+- [ ] **Step 2: Add the 3 DTO records to `WorkerClient.cs`**
+
+In `src/ClaudeDo.Ui/Services/WorkerClient.cs`, immediately after line 534
+(`public record MergeTargetsDto(...)`), add:
+
+```csharp
+public record MergeConflictsDto(string TaskId, IReadOnlyList<ConflictFileDto> Files);
+public record ConflictFileDto(string Path, IReadOnlyList<ConflictHunkDto> Hunks);
+public record ConflictHunkDto(string Ours, string Theirs, string? Base);
+```
+
+- [ ] **Step 3: Add the 5 client method bodies to `WorkerClient.cs`**
+
+In `src/ClaudeDo.Ui/Services/WorkerClient.cs`, right after the `MergeTaskAsync`
+method (ends at line 270), add:
+
+```csharp
+    public Task<MergeResultDto> StartConflictMergeAsync(string taskId, string targetBranch)
+        => _hub.InvokeAsync<MergeResultDto>("StartConflictMerge", taskId, targetBranch);
+
+    public Task<MergeConflictsDto> GetMergeConflictsAsync(string taskId)
+        => _hub.InvokeAsync<MergeConflictsDto>("GetMergeConflicts", taskId);
+
+    public Task WriteConflictResolutionAsync(string taskId, string path, string resolvedContent)
+        => _hub.InvokeAsync("WriteConflictResolution", taskId, path, resolvedContent);
+
+    public Task<MergeResultDto> ContinueMergeAsync(string taskId)
+        => _hub.InvokeAsync<MergeResultDto>("ContinueMerge", taskId);
+
+    public Task AbortMergeAsync(string taskId)
+        => _hub.InvokeAsync("AbortMerge", taskId);
+```
+
+- [ ] **Step 4: Build the UI project**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj -c Release`
+Expected: build FAILS — the two test projects won't compile yet, but the UI project
+itself should succeed. If the UI project reports "does not implement interface member"
+it means a body is missing; fix before continuing. (Test projects are fixed in 0.2.)
+
+### Task 0.2: Update the hand-rolled test fakes
+
+**Files:**
+- Modify: `tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs`
+- Modify: `tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs`
+
+- [ ] **Step 1: Add 5 virtual no-ops to `StubWorkerClient`**
+
+In `tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs`, after the `MergeTaskAsync` override
+(line 57), add:
+
+```csharp
+    public virtual Task<MergeResultDto> StartConflictMergeAsync(string taskId, string targetBranch) => Task.FromResult(new MergeResultDto("conflict", System.Array.Empty<string>(), null));
+    public virtual Task<MergeConflictsDto> GetMergeConflictsAsync(string taskId) => Task.FromResult(new MergeConflictsDto(taskId, System.Array.Empty<ConflictFileDto>()));
+    public virtual Task WriteConflictResolutionAsync(string taskId, string path, string resolvedContent) => Task.CompletedTask;
+    public virtual Task<MergeResultDto> ContinueMergeAsync(string taskId) => Task.FromResult(new MergeResultDto("merged", System.Array.Empty<string>(), null));
+    public virtual Task AbortMergeAsync(string taskId) => Task.CompletedTask;
+```
+
+- [ ] **Step 2: Add 5 methods to `FakeWorkerClient`**
+
+In `tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs`, after the
+`MergeTaskAsync` method (line 47), add:
+
+```csharp
+    public Task<MergeResultDto> StartConflictMergeAsync(string taskId, string targetBranch) => Task.FromResult(new MergeResultDto("conflict", System.Array.Empty<string>(), null));
+    public Task<MergeConflictsDto> GetMergeConflictsAsync(string taskId) => Task.FromResult(new MergeConflictsDto(taskId, System.Array.Empty<ConflictFileDto>()));
+    public Task WriteConflictResolutionAsync(string taskId, string path, string resolvedContent) => Task.CompletedTask;
+    public Task<MergeResultDto> ContinueMergeAsync(string taskId) => Task.FromResult(new MergeResultDto("merged", System.Array.Empty<string>(), null));
+    public Task AbortMergeAsync(string taskId) => Task.CompletedTask;
+```
+
+- [ ] **Step 3: Build both test projects**
+
+Run: `dotnet build tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release && dotnet build tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release`
+Expected: both BUILD succeed.
+
+- [ ] **Step 4: Run the UI test suite to confirm green baseline**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`
+Expected: PASS (no behavior changed yet).
+
+### Task 0.3: Commit and push the foundation
+
+- [ ] **Step 1: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Services/Interfaces/IWorkerClient.cs src/ClaudeDo.Ui/Services/WorkerClient.cs tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs
+git commit -m "feat(ui): add conflict-resolution worker contract (foundation for merge rework)"
+```
+
+- [ ] **Step 2: Push so Layer B/C can branch from this commit**
+
+Run: `git push`
+Expected: pushed to `main`. (First push to git.kuns.dev may fail auth — retry once.)
+**This commit is the branch point for the Layer B and Layer C kickoff prompts.**
+
+---
+
+## Phase A — Layer A Review/Merge Cockpit
+
+### Task A.1: Conflict-resolution seam + route Approve/Merge conflicts into it (TDD)
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs`
+- Test: `tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandConflictSeamTests.cs` (new)
+
+- [ ] **Step 1: Write the failing test**
+
+Create `tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandConflictSeamTests.cs`. Mirror
+the VM-construction harness used in
+`tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandPlanningTests.cs` (same folder) —
+construct `DetailsIslandViewModel` exactly as that file does, including its
+`StubWorkerClient` subclass pattern. The test:
+
+```csharp
+[Fact]
+public async Task ApproveReview_OnConflict_InvokesConflictResolutionSeam()
+{
+    string? resolvedTaskId = null;
+    string? resolvedTarget = null;
+
+    // Construct the VM as in DetailsIslandPlanningTests, with a worker stub whose
+    // ApproveReviewAsync returns a conflict result:
+    //   public override Task<MergeResultDto?> ApproveReviewAsync(string id, string target)
+    //       => Task.FromResult<MergeResultDto?>(new MergeResultDto("conflict", new[]{"a.cs"}, null));
+    var vm = CreateVm(/* worker stub above */);
+    vm.RequestConflictResolution = (taskId, target) =>
+    {
+        resolvedTaskId = taskId; resolvedTarget = target;
+        return System.Threading.Tasks.Task.CompletedTask;
+    };
+    // assign a task in WaitingForReview + a SelectedMergeTarget = "main" via the same
+    // helpers DetailsIslandPlanningTests uses.
+
+    await vm.ApproveReviewCommand.ExecuteAsync(null);
+
+    Assert.Equal(/* the seeded task id */, resolvedTaskId);
+    Assert.Equal("main", resolvedTarget);
+}
+```
+
+- [ ] **Step 2: Run the test to verify it fails**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter ApproveReview_OnConflict_InvokesConflictResolutionSeam`
+Expected: FAIL — `RequestConflictResolution` property does not exist (compile error).
+
+- [ ] **Step 3: Add the seam property**
+
+In `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs`, beside the other
+view-wired delegates (`ShowDiffModal`, `ShowMergeModal` around line 387–390), add:
+
+```csharp
+    // Invoked when a single-task merge/approve hits a conflict. Wired by the
+    // integrator to Layer C's conflict resolver. Args: (taskId, targetBranch).
+    public Func<string, string, System.Threading.Tasks.Task>? RequestConflictResolution { get; set; }
+```
+
+- [ ] **Step 4: Route the Approve conflict branch into the seam**
+
+In `ApproveReviewAsync` (around line 1453), replace the conflict branch body so it
+prefers the seam, falling back to the current preview-text behavior:
+
+```csharp
+            var result = await _worker.ApproveReviewAsync(Task.Id, SelectedMergeTarget ?? "");
+            if (result?.Status == "conflict")
+            {
+                if (RequestConflictResolution is not null)
+                {
+                    await RequestConflictResolution(Task.Id, SelectedMergeTarget ?? "");
+                }
+                else
+                {
+                    var (text, _, _) = MergePreviewPresenter.Describe(
+                        new MergePreviewDto("conflict", result.ConflictFiles, 0));
+                    MergePreviewText = text; MergeIsClean = false; MergeIsConflict = true;
+                }
+            }
+```
+
+- [ ] **Step 5: Route the manual Merge conflict branch into the seam**
+
+In `MergeAsync` (around line 1170), apply the same pattern to its conflict branch:
+
+```csharp
+            var result = await _worker.MergeTaskAsync(Task.Id, SelectedMergeTarget ?? "", false, "Merge task");
+            if (result.Status == "conflict")
+            {
+                if (RequestConflictResolution is not null)
+                {
+                    await RequestConflictResolution(Task.Id, SelectedMergeTarget ?? "");
+                }
+                else
+                {
+                    var (text, _, _) = MergePreviewPresenter.Describe(
+                        new MergePreviewDto("conflict", result.ConflictFiles, 0));
+                    MergePreviewText = text; MergeIsClean = false; MergeIsConflict = true;
+                }
+            }
+            else
+            {
+                await RefreshMergePreviewAsync();
+            }
+```
+
+- [ ] **Step 6: Run the test to verify it passes**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter ApproveReview_OnConflict_InvokesConflictResolutionSeam`
+Expected: PASS.
+
+- [ ] **Step 7: Run the full UI suite (no regressions)**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`
+Expected: PASS.
+
+- [ ] **Step 8: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandConflictSeamTests.cs
+git commit -m "feat(ui): route single-task merge conflicts into a resolution seam"
+```
+
+### Task A.2: Fuse the Git tab into one Approve+merge cockpit
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml`
+
+- [ ] **Step 1: Replace the two Git-tab sections with one cockpit block**
+
+In `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml`, replace the entire Git
+`ScrollViewer` body (lines 255–313 — the `<!-- Git: ... -->` block containing the
+separate `REVIEW` `StackPanel` and the `MERGE & WORKTREE` `StackPanel`) with a single
+cockpit where Approve sits with the merge target/preview/actions. Keep the existing
+control class names (`section-label`, `field-label`, `btn`, `btn accent`, `meta`) and
+the existing bindings (`SelectedMergeTarget`, `MergeTargetBranches`, `MergePreviewText`,
+`MergeIsClean`, `MergeIsConflict`, `ShowMergePreviewMuted`, `OpenDiffCommand`,
+`ApproveReviewCommand`, `MergeCommand`, `ShowSingleMerge`, `OpenWorktreeCommand`,
+`ReviewCombinedDiffCommand`, `MergeAllCommand`, `CanMergeAll`, `MergeAllDisabledReason`,
+`MergeAllError`):
+
+```xml
+        <!-- Git: one Approve + merge cockpit -->
+        <ScrollViewer IsVisible="{Binding IsGitTab}" Padding="14,10">
+          <StackPanel Spacing="12" IsVisible="{Binding ShowMergeSection}">

+
+Note: the cockpit now shows whenever `ShowMergeSection` is true. `ShowMergeSection`
+(DetailsIslandViewModel line 161) must be true while `IsWaitingForReview` so the
+Approve button appears. Check its expression in Step 2.
+
+- [ ] **Step 2: Verify `ShowMergeSection` covers the review state**
+
+Read `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs` line 161. If
+`ShowMergeSection` is false while `IsWaitingForReview` (e.g. it requires a non-review
+state), widen it to also be true when `IsWaitingForReview && WorktreePath != null`, and
+ensure `OnPropertyChanged(nameof(ShowMergeSection))` already fires on the relevant state
+transitions (it is notified via `NotifySessionSections`). Make the minimal change needed
+so the Approve button is visible in review state. If it already covers review, change
+nothing.
+
+- [ ] **Step 3: Build the app project**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: BUILD succeeds (pulls in Ui + Data).
+
+- [ ] **Step 4: Visual verification (manual — flag for the user)**
+
+This is an AXAML layout change with no automated coverage. Launch the app, open a task
+in `WaitingForReview`, open the Git tab, and confirm: the single MERGE block shows the
+target combo, the colored preview line, an "Approve & Merge" button (review state), and
+the diff/worktree/combined/merge-all actions. **Explicitly tell the user this needs a
+visual pass — do not claim it works without running it.**
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs
+git commit -m "feat(ui): fuse git tab into one approve+merge cockpit"
+```
+
+### Task A.3: Verify diff-renderer consolidation
+
+**Files:** none modified (verification only).
+
+- [ ] **Step 1: Confirm DiffModal + Planning already use the canonical renderer**
+
+Run: `rg -l "DiffLinesView" src/ClaudeDo.Ui/Views`
+Expected: matches in `Modals/DiffModalView.axaml` and `Planning/PlanningDiffView.axaml`.
+If `PlanningDiffView.axaml` does NOT use `DiffLinesView`, change its diff `ItemsControl`
+to a `<controls:DiffLinesView Lines="{Binding SelectedFile.Lines}" />` (matching
+`DiffModalView.axaml`'s usage) and rebuild the App project. If both already use it, this
+task is a no-op — record that and move on. (`WorktreeModalView`'s bespoke diff is
+intentionally left for Layer B.)
+
+---
+
+## Self-Review
+
+- **Spec coverage:** Foundation contract (spec §"Frozen worker conflict contract") →
+  Task 0.1. Test fakes (spec parallel-boundaries row) → Task 0.2. Branch point (spec
+  §"built & pushed this session") → Task 0.3. Layer A cockpit + Approve/merge flow
+  together (spec §"Layer A") → Task A.2. Single-task approve-on-conflict opens resolver
+  via seam (spec §"Layer A" + §"integration seams") → Task A.1. Diff consolidation
+  (spec §"One diff model") → Task A.3. Output-footer feedback unchanged → not touched
+  (correct). No spec requirement left unmapped for this session's scope.
+- **Placeholder scan:** none — every code step has concrete code; the only "mirror the
+  existing harness" reference (Task A.1 Step 1) points at a real file with a working
+  pattern, not a TODO.
+- **Type consistency:** `MergeConflictsDto`/`ConflictFileDto`/`ConflictHunkDto` and the
+  5 method names match between `IWorkerClient` (0.1 Step 1), `WorkerClient` (0.1 Steps
+  2–3), and both fakes (0.2). The seam `RequestConflictResolution` is
+  `Func<string,string,Task>?` everywhere (A.1 Steps 1, 3–5). DTO field names match the
+  spec.
+
+---
+
+## Integration notes (for the integrator merging A + B + C)
+
+- Wire `DetailsIslandViewModel.RequestConflictResolution` and Layer B's equivalent
+  callback to Layer C's `ConflictResolverViewModel` factory + `ShowConflictResolver`
+  dialog delegate.
+- Layer C implements the worker hub methods `StartConflictMerge`, `GetMergeConflicts`,
+  `WriteConflictResolution`, `ContinueMerge`, `AbortMerge`; the client side from Task
+  0.1 already calls them by name.

+# Git Merge/Review Rework — Parallel Kickoff Prompts (Layer B & Layer C)
+
+These are self-contained prompts to paste into two fresh ClaudeDo sessions, each in its
+own git worktree, run **in parallel** with the main session's Layer A work.
+
+**Prerequisite — branch point:** Both sessions must branch from `main` **at or after**
+the foundation commit `feat(ui): add conflict-resolution worker contract (foundation for
+merge rework)` (Phase 0, Task 0.3 of
+`docs/superpowers/plans/2026-06-05-git-merge-review-foundation-layerA.md`). That commit
+adds the frozen `IWorkerClient` conflict contract both layers rely on. Do not start B/C
+until that commit is pushed.
+
+**Integration:** Neither session pushes to `main` or merges. Each leaves its branch/
+worktree for the orchestrator (the main session) to review and merge.
+
+Design reference for both: `docs/superpowers/specs/2026-06-05-git-merge-review-rework-design.md`
+
+---
+
+## Layer B — Multi-worktree merge cockpit
+
+```
+We're reworking ClaudeDo's merge/review UX. Your job is Layer B: a multi-worktree merge
+cockpit. The overall design is in docs/superpowers/specs/2026-06-05-git-merge-review-rework-design.md
+(read the "Layer B" section and "Parallel boundaries" table first). A shared foundation
+commit ("add conflict-resolution worker contract") is already on main — branch from it.
+
+First, create an isolated worktree for this work (use the superpowers:using-git-worktrees
+skill). Then write a plan (superpowers:writing-plans) for just Layer B and implement it
+with superpowers:subagent-driven-development (sonnet subagents, TDD, commit per task).
+
+Scope:
+- Rework WorktreesOverviewModalView + WorktreesOverviewModalViewModel into a batch-merge
+  cockpit: list mergeable worktrees, multi-select N, pick ONE target branch, "Merge all".
+- Skip-and-continue: loop the EXISTING IWorkerClient.MergeTaskAsync(taskId, target,
+  removeWorktree:false, msg) over the selected tasks. Clean ones merge; conflicting ones
+  (MergeTaskAsync returns Status=="conflict", auto-aborts leaving the tree clean) are
+  collected into a "needs resolution" list shown with live progress.
+- Each conflict row gets a "Resolve" button that invokes a seam:
+  public Func<string, string, Task>? RequestConflictResolution { get; set; }  // (taskId, targetBranch)
+  Define this callback property on the cockpit VM; leave it unwired (the orchestrator
+  wires it to Layer C's resolver at merge time). Do NOT reference any ConflictResolver
+  type.
+- Migrate WorktreeModalView's bespoke inline diff onto the canonical DiffLinesView
+  control (src/ClaudeDo.Ui/Views/Controls/DiffLinesView.axaml) using DiffFileViewModel/
+  DiffLineViewModel/UnifiedDiffParser (src/ClaudeDo.Ui/ViewModels/Modals/). This removes
+  the last duplicate diff renderer.
+
+Reuse these existing IWorkerClient methods (already implemented): MergeTaskAsync,
+GetMergeTargetsAsync, GetWorktreesOverviewAsync, SetWorktreeStateAsync,
+CleanupFinishedWorktreesAsync, ForceRemoveWorktreeAsync.
+
+Do NOT touch (other layers own them): any worker-side files (WorkerHub, TaskMergeService,
+GitService), IWorkerClient.cs / WorkerClient.cs, WorkConsole.axaml,
+DetailsIslandViewModel.cs, or create the ConflictResolver UI.
+
+Build with: dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release (a running
+Worker locks Debug — use Release). Keep locales/en.json and de.json keys in parity if you
+add any. If you change IWorkerClient (you shouldn't need to), update the hand-rolled fakes
+in tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs and
+tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs. No tests that spawn
+the real claude CLI.
+
+Commit per task with Conventional Commits. Do NOT push to main and do NOT merge — leave
+your worktree/branch for the orchestrator. Flag any AXAML layout for visual verification
+rather than claiming it works.

+
+## Layer C — Inline conflict resolver
+
+```
+We're reworking ClaudeDo's merge/review UX. Your job is Layer C: an in-app, VSCode-style
+inline conflict resolver, plus the worker plumbing it needs. The overall design is in
+docs/superpowers/specs/2026-06-05-git-merge-review-rework-design.md (read the "Layer C",
+"Frozen worker conflict contract", and "Parallel boundaries" sections first). A shared
+foundation commit ("add conflict-resolution worker contract") is already on main — branch
+from it. That commit already wired the CLIENT side (IWorkerClient + WorkerClient call
+these hub methods by name); your job includes implementing the matching WORKER hub methods.
+
+First, create an isolated worktree (superpowers:using-git-worktrees). Then write a plan
+(superpowers:writing-plans) for Layer C and implement it with
+superpowers:subagent-driven-development (sonnet subagents, TDD, commit per task).
+
+Worker side — implement these 5 hub methods in WorkerHub (names/params/returns MUST match
+the client calls already shipped in the foundation):
+- StartConflictMerge(string taskId, string targetBranch) -> MergeResultDto
+    Calls TaskMergeService.MergeAsync with leaveConflictsInTree:true (the overload/flag
+    already exists — used today by PlanningMergeOrchestrator). Leaves .git/MERGE_HEAD in
+    the list's WorkingDir, returns Status="conflict" + conflict file list.
+- GetMergeConflicts(string taskId) -> MergeConflictsDto
+    For each conflicted file (git diff --name-only --diff-filter=U), read ours/theirs/base
+    via `git show :2:<path>` / `:3:<path>` / `:1:<path>`. Add GitService helpers as needed.
+- WriteConflictResolution(string taskId, string path, string resolvedContent) -> void
+    Write resolvedContent to the file in WorkingDir and `git add` it.
+- ContinueMerge(string taskId) -> MergeResultDto
+    Wrap the EXISTING TaskMergeService.ContinueMergeAsync (git add -A → re-check
+    diff --diff-filter=U → git commit). Currently service-level only; expose it on the hub.
+- AbortMerge(string taskId) -> void
+    Wrap the EXISTING TaskMergeService.AbortMergeAsync (git merge --abort).
+
+Define worker-side DTO records that serialize identically to the client records already in
+WorkerClient.cs:
+    MergeConflictsDto(string TaskId, IReadOnlyList<ConflictFileDto> Files)
+    ConflictFileDto(string Path, IReadOnlyList<ConflictHunkDto> Hunks)
+    ConflictHunkDto(string Ours, string Theirs, string? Base)
+(place beside the other hub DTOs in WorkerHub.cs). MergeResultDto already exists.
+
+UI side — new files only:
+- ConflictResolverViewModel + ConflictResolverView. On open: StartConflictMergeAsync then
+  GetMergeConflictsAsync(taskId). Per conflict hunk show ours vs theirs stacked with
+  buttons Accept Current / Accept Incoming / Accept Both / Edit manually, plus a free-text
+  box for the merged result of that hunk. Use the UI conflict model from the design
+  (ConflictFile { Path, Hunks[] }, ConflictHunk { Ours, Theirs, Base, Resolution }) —
+  shape it so a future 3-way pane needs no model change.
+- When every file is resolved: WriteConflictResolutionAsync per file, then
+  ContinueMergeAsync(taskId) (Status "merged" closes; "conflict" means not fully resolved,
+  stay open). AbortMergeAsync(taskId) cancels.
+- Expose a factory Func<string, ConflictResolverViewModel> and a
+  Func<ConflictResolverViewModel, Task> ShowConflictResolver dialog delegate for the
+  orchestrator to wire to Layer A/B's RequestConflictResolution(taskId, target) seams.
+
+Do NOT touch (other layers own them): WorkerClient.cs, IWorkerClient.cs (already wired),
+WorkConsole.axaml, DetailsIslandViewModel.cs, WorktreesOverviewModalView/VM. You WILL need
+to add the 5 worker hub methods + GitService conflict reads.
+
+Tests: add worker tests for the conflict reads / continue / abort using real SQLite + real
+git (follow existing GitService/TaskMergeService test patterns). NEVER spawn the real
+claude CLI. If you change IWorkerClient (you should NOT — client is frozen), update the
+fakes in both test projects.
+
+Build with: dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release and
+dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release (a running Worker locks
+Debug). Keep locales/en.json and de.json in parity for any new UI strings.
+
+Commit per task with Conventional Commits. Do NOT push to main and do NOT merge — leave
+your worktree/branch for the orchestrator. Flag the resolver UI for visual verification.

+# Layer C — Inline Conflict Resolver Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build the worker-side conflict plumbing (5 frozen hub methods + GitService reads) and a VSCode-style in-app inline conflict resolver UI for ClaudeDo's merge rework.
+
+**Architecture:** The worker performs a real merge that leaves conflicts in the list's working tree (`leaveConflictsInTree:true`), exposes ours/theirs/base per conflicted file via `git show :2:/:3:/:1:`, accepts written resolutions, and finishes via the existing `ContinueMergeAsync`/`AbortMergeAsync`. The UI presents each conflicted file's hunk with Accept Current/Incoming/Both/Edit-manually controls plus a free-text merged box, then writes resolutions and continues.
+
+**Tech Stack:** .NET 8, ASP.NET Core SignalR (WorkerHub), EF Core/SQLite, Avalonia MVVM (CommunityToolkit), xUnit + real git/SQLite fixtures.
+
+**Frozen client contract (already shipped in foundation commit `2dfc455`, DO NOT edit):**
+- `IWorkerClient` / `WorkerClient.cs` already call hub methods by name: `StartConflictMerge`, `GetMergeConflicts`, `WriteConflictResolution`, `ContinueMerge`, `AbortMerge`.
+- Client DTOs already exist in `WorkerClient.cs`: `MergeConflictsDto(string TaskId, IReadOnlyList<ConflictFileDto> Files)`, `ConflictFileDto(string Path, IReadOnlyList<ConflictHunkDto> Hunks)`, `ConflictHunkDto(string Ours, string Theirs, string? Base)`, plus existing `MergeResultDto(string Status, IReadOnlyList<string> ConflictFiles, string? ErrorMessage)`.
+- Worker-side DTOs must serialize identically (same record shape) and live in `WorkerHub.cs`.
+
+**Do NOT touch:** `WorkerClient.cs`, `Interfaces/IWorkerClient.cs`, `WorkConsole.axaml`, `DetailsIslandViewModel.cs`, `WorktreesOverviewModalView/VM`, `WorktreeModalView`. Test fakes for `IWorkerClient` already implement the 5 methods as no-op stubs (`StubWorkerClient` is `virtual` in Ui.Tests) — subclass/override, never edit the interface.
+
+**Build/test commands (.NET 8 — running Worker locks `Debug`, always `-c Release`):**
+```bash
+dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release
+dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release
+dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release
+dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release
+dotnet test tests/ClaudeDo.Localization.Tests/ClaudeDo.Localization.Tests.csproj -c Release
+```
+
+---
+
+## File Structure
+
+**Worker / Data (create + modify):**
+- Modify `src/ClaudeDo.Data/Git/GitService.cs` — add `ShowStageAsync` (untrimmed blob read) + `AddPathAsync`; add `trimOutput` param to `RunGitAsync`.
+- Modify `src/ClaudeDo.Worker/Lifecycle/TaskMergeService.cs` — add records `MergeConflicts`/`ConflictFileContent`; add `GetConflictsAsync` + `WriteResolutionAsync`.
+- Modify `src/ClaudeDo.Worker/Hub/WorkerHub.cs` — add DTOs `MergeConflictsDto`/`ConflictFileDto`/`ConflictHunkDto` + 5 hub methods.
+
+**UI (create new only):**
+- Create `src/ClaudeDo.Ui/ViewModels/Conflicts/ConflictModels.cs` — `ConflictFile`, `ConflictHunk`.
+- Create `src/ClaudeDo.Ui/ViewModels/Conflicts/ConflictResolverViewModel.cs`.
+- Create `src/ClaudeDo.Ui/Views/Conflicts/ConflictResolverView.axaml` + `.axaml.cs`.
+
+**Wiring (modify):**
+- Modify `src/ClaudeDo.App/Program.cs` — register `ConflictResolverViewModel` + `Func<string, ConflictResolverViewModel>`.
+- Modify `src/ClaudeDo.Ui/ViewModels/IslandsShellViewModel.cs` — additive seam (`ConflictResolverFactory`, `ShowConflictResolver`, `RequestConflictResolutionAsync`).
+- Modify `src/ClaudeDo.Ui/Views/MainWindow.axaml.cs` — wire `ShowConflictResolver` dialog delegate.
+- Modify `src/ClaudeDo.Localization/locales/en.json` + `de.json` — `conflictResolver.*` keys (parity enforced by Localization.Tests).
+
+**Tests (create + modify):**
+- Modify `tests/ClaudeDo.Worker.Tests/Services/TaskMergeServiceTests.cs` — conflict-read / write-resolution / round-trip tests.
+- Create `tests/ClaudeDo.Ui.Tests/ViewModels/ConflictResolverViewModelTests.cs`.
+
+---
+
+## Task 1: GitService conflict-blob reads
+
+**Files:**
+- Modify: `src/ClaudeDo.Data/Git/GitService.cs`
+- Test: `tests/ClaudeDo.Worker.Tests/Services/TaskMergeServiceTests.cs` (GitService exercised here via real repo; add focused tests in Task 2 round-trip)
+
+- [ ] **Step 1: Add `trimOutput` param to `RunGitAsync`** so blob reads keep exact bytes.
+
+In `RunGitAsync` signature add `bool trimOutput = true`, and change the return to:
+```csharp
+return (proc.ExitCode, trimOutput ? stdout.TrimEnd() : stdout, stderr.TrimEnd());
+```
+(All existing callers keep the default `true`.)
+
+- [ ] **Step 2: Add `ShowStageAsync` + `AddPathAsync`** (place after `ListConflictedFilesAsync`):
+
+```csharp
+/// <summary>
+/// Reads a conflicted file's blob at a merge stage: 1=base, 2=ours, 3=theirs.
+/// Returns null when the stage doesn't exist (e.g. add/add conflict has no base).
+/// Output is NOT trimmed so file content round-trips exactly.
+/// </summary>
+public async Task<string?> ShowStageAsync(string repoDir, int stage, string path, CancellationToken ct = default)
+{
+    var (exitCode, stdout, _) = await RunGitAsync(repoDir, ["show", $":{stage}:{path}"], ct, trimOutput: false);
+    return exitCode == 0 ? stdout : null;
+}
+
+public async Task AddPathAsync(string repoDir, string path, CancellationToken ct = default)
+{
+    var (exitCode, _, stderr) = await RunGitAsync(repoDir, ["add", "--", path], ct);
+    if (exitCode != 0)
+        throw new InvalidOperationException($"git add '{path}' failed (exit {exitCode}): {stderr}");
+}
+```
+
+- [ ] **Step 3: Build the Data + Worker projects to verify compilation.**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/ClaudeDo.Data/Git/GitService.cs
+git commit -m "feat(git): add conflict-stage blob reads and single-path staging"
+```
+

+
+## Task 2: TaskMergeService conflict reads + resolution writes
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Lifecycle/TaskMergeService.cs`
+- Test: `tests/ClaudeDo.Worker.Tests/Services/TaskMergeServiceTests.cs`
+
+- [ ] **Step 1: Write failing tests** (append inside `TaskMergeServiceTests`, before `#region Test doubles`). Reuse the existing helpers `SeedListAndTask`, `SeedWorktree`, `BuildService`, and the `GitRepoFixture` conflict setup pattern from `ContinueMergeAsync_AfterUserResolves...`.
+

+- [ ] **Step 2: Run tests to verify they fail** (no such methods).
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release --filter "GetConflictsAsync_AfterConflictMerge_ReturnsOursAndTheirs|WriteResolutionAsync_ThenContinue_CompletesMerge"`
+Expected: compile error / FAIL (methods don't exist).
+
+- [ ] **Step 3: Add records + methods to `TaskMergeService.cs`.**
+
+Add records beside `MergeResult` (top of file, after the existing record declarations):
+```csharp
+public sealed record MergeConflicts(
+    string TaskId,
+    IReadOnlyList<ConflictFileContent> Files);
+
+public sealed record ConflictFileContent(
+    string Path,
+    string Ours,
+    string Theirs,
+    string? Base);
+```
+
+Add methods inside the class (after `AbortMergeAsync`):
+```csharp
+public async Task<MergeConflicts> GetConflictsAsync(string taskId, CancellationToken ct)
+{
+    var (_, list, _) = await LoadMergeContextAsync(taskId, ct);
+    if (string.IsNullOrWhiteSpace(list.WorkingDir))
+        throw new InvalidOperationException("list has no working directory");
+
+    var files = await _git.ListConflictedFilesAsync(list.WorkingDir, ct);
+    var result = new List<ConflictFileContent>(files.Count);
+    foreach (var path in files)
+    {
+        var ours   = await _git.ShowStageAsync(list.WorkingDir, 2, path, ct) ?? "";
+        var theirs = await _git.ShowStageAsync(list.WorkingDir, 3, path, ct) ?? "";
+        var @base  = await _git.ShowStageAsync(list.WorkingDir, 1, path, ct);
+        result.Add(new ConflictFileContent(path, ours, theirs, @base));
+    }
+    return new MergeConflicts(taskId, result);
+}
+
+public async Task WriteResolutionAsync(string taskId, string path, string content, CancellationToken ct)
+{
+    var (_, list, _) = await LoadMergeContextAsync(taskId, ct);
+    if (string.IsNullOrWhiteSpace(list.WorkingDir))
+        throw new InvalidOperationException("list has no working directory");
+
+    var full = Path.Combine(list.WorkingDir, path.Replace('/', Path.DirectorySeparatorChar));
+    await File.WriteAllTextAsync(full, content, ct);
+    await _git.AddPathAsync(list.WorkingDir, path, ct);
+}
+```
+(Note: `Path` is `System.IO.Path` — the file already uses it via other helpers; the record property `Path` does not shadow it inside these methods because it's accessed as a static type, not an instance member.)
+
+- [ ] **Step 4: Run the tests to verify they pass.**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release --filter "GetConflictsAsync_AfterConflictMerge_ReturnsOursAndTheirs|WriteResolutionAsync_ThenContinue_CompletesMerge"`
+Expected: PASS (2 tests). If git unavailable they no-op.

+```bash
+git add src/ClaudeDo.Worker/Lifecycle/TaskMergeService.cs tests/ClaudeDo.Worker.Tests/Services/TaskMergeServiceTests.cs

+## Task 3: WorkerHub conflict methods + DTOs
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Hub/WorkerHub.cs`
+
+- [ ] **Step 1: Add DTOs** beside the existing merge DTOs (after `public record MergeTargetsDto(...)`):

+## Task 6: ConflictResolverView + localization
+
+**Files:**
+- Create: `src/ClaudeDo.Ui/Views/Conflicts/ConflictResolverView.axaml`
+- Create: `src/ClaudeDo.Ui/Views/Conflicts/ConflictResolverView.axaml.cs`
+- Modify: `src/ClaudeDo.Localization/locales/en.json`
+- Modify: `src/ClaudeDo.Localization/locales/de.json`
+
+- [ ] **Step 1: Add localization keys** to `en.json` as a new top-level section (sibling of `"planning"`):
+
+```json
+  "conflictResolver": {
+    "windowTitle": "Resolve merge conflicts",
+    "modalTitle": "RESOLVE CONFLICTS",
+    "loading": "Loading conflicts…",

+    "mergedResult": "Merged result",
+    "acceptCurrent": "Accept Current",
+    "acceptIncoming": "Accept Incoming",
+    "acceptBoth": "Accept Both",
+    "editManually": "Edit manually",
+    "continue": "Resolve & continue",
+    "abort": "Abort merge"
+  },
+```
+
+- [ ] **Step 2: Add the SAME keys to `de.json`** (German values, identical key set — parity enforced by Localization.Tests):

+**Note for the implementer:** if `MonoFont` / `path-mono` / `heading` / `meta` / `btn` resource keys or style classes don't resolve at build, drop the `FontFamily` attribute and unknown `Classes` (keep `btn`) — match whatever the existing `ConflictResolutionView.axaml` and app styles actually expose. Verify against `src/ClaudeDo.Ui/Views/Planning/ConflictResolutionView.axaml` and the app's style resources before finalizing.
+
+- [ ] **Step 4: Create the code-behind** (`ConflictResolverView.axaml.cs`):
+
+```csharp
+using Avalonia.Controls;
+using ClaudeDo.Ui.ViewModels.Conflicts;
+
+namespace ClaudeDo.Ui.Views.Conflicts;
+
+public partial class ConflictResolverView : Window
+{
+    public ConflictResolverView()
+    {
+        InitializeComponent();
+    }
+
+    protected override void OnDataContextChanged(System.EventArgs e)
+    {
+        base.OnDataContextChanged(e);
+        if (DataContext is ConflictResolverViewModel vm)
+            vm.CloseRequested = Close;
+    }
+}
+```
+
+- [ ] **Step 5: Build the App + run Localization tests.**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release && dotnet test tests/ClaudeDo.Localization.Tests/ClaudeDo.Localization.Tests.csproj -c Release`
+Expected: Build succeeded; localization parity tests PASS.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/Conflicts/ConflictResolverView.axaml src/ClaudeDo.Ui/Views/Conflicts/ConflictResolverView.axaml.cs src/ClaudeDo.Localization/locales/en.json src/ClaudeDo.Localization/locales/de.json

+
+## Task 7: Wire factory + dialog seam for the integrator
+
+**Files:**
+- Modify: `src/ClaudeDo.App/Program.cs`
+- Modify: `src/ClaudeDo.Ui/ViewModels/IslandsShellViewModel.cs`
+- Modify: `src/ClaudeDo.Ui/Views/MainWindow.axaml.cs`
+
+These are additive seams only. The integrator connects Layer A/B's `RequestConflictResolution(taskId, target)` callback to `IslandsShellViewModel.RequestConflictResolutionAsync`.
+
+- [ ] **Step 1: Register the factory in `Program.cs`** (in the ViewModels region, near the other `Func<>` factories). Only the `Func<>` factory is needed — the VM is never resolved directly:
+
+```csharp
+sc.AddSingleton<Func<string, ClaudeDo.Ui.ViewModels.Conflicts.ConflictResolverViewModel>>(sp =>
+    taskId => new ClaudeDo.Ui.ViewModels.Conflicts.ConflictResolverViewModel(
+        sp.GetRequiredService<WorkerClient>(), taskId));
+```
+Then, after `IslandsShellViewModel` is registered, set the factory on it once resolved. Replace the existing `sc.AddSingleton<IslandsShellViewModel>();` registration with a factory that injects the conflict-resolver factory:
+
+```csharp
+sc.AddSingleton<IslandsShellViewModel>(sp =>
+{
+    var shell = ActivatorUtilities.CreateInstance<IslandsShellViewModel>(sp);
+    shell.ConflictResolverFactory =
+        sp.GetRequiredService<Func<string, ClaudeDo.Ui.ViewModels.Conflicts.ConflictResolverViewModel>>();
+    return shell;
+});
+```
+(`ActivatorUtilities.CreateInstance` resolves the existing big constructor + its `Func<>` deps exactly as the default registration did.)
+
+- [ ] **Step 2: Add the additive seam to `IslandsShellViewModel`** (near the other `Show*` delegate properties):
+
+```csharp
+// Layer C seam: composition root sets the factory; MainWindow sets the dialog opener.
+// The integrator connects Layer A/B's RequestConflictResolution(taskId, target) to this method.
+public Func<string, ClaudeDo.Ui.ViewModels.Conflicts.ConflictResolverViewModel>? ConflictResolverFactory { get; set; }
+public Func<ClaudeDo.Ui.ViewModels.Conflicts.ConflictResolverViewModel, Task>? ShowConflictResolver { get; set; }
+
+public async Task RequestConflictResolutionAsync(string taskId, string targetBranch)
+{
+    if (ConflictResolverFactory is null || ShowConflictResolver is null) return;
+    var vm = ConflictResolverFactory(taskId);
+    var hasConflicts = await vm.OpenAsync(targetBranch);
+    if (hasConflicts)
+        await ShowConflictResolver(vm);
+}
+```
+(Add `using ClaudeDo.Ui.ViewModels.Conflicts;` or use fully-qualified names as above.)
+
+- [ ] **Step 3: Wire the dialog opener in `MainWindow.axaml.cs`** inside `OnDataContextChanged`, alongside the other `vm.Show*` assignments:
+
+```csharp
+vm.ShowConflictResolver = async (resolverVm) =>
+{
+    var dlg = new ClaudeDo.Ui.Views.Conflicts.ConflictResolverView { DataContext = resolverVm };
+    await dlg.ShowDialog(this);
+};
+```
+
+- [ ] **Step 4: Build the App to verify compilation.**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: Build succeeded.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.App/Program.cs src/ClaudeDo.Ui/ViewModels/IslandsShellViewModel.cs src/ClaudeDo.Ui/Views/MainWindow.axaml.cs
+git commit -m "feat(ui): expose conflict-resolver factory and dialog seam for integrator"
+```
+
+---
+
+## Task 8: Full verification
+
+- [ ] **Step 1: Build both head projects.**
+
+Run:
+```bash
+dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj -c Release
+dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release
+```
+Expected: both Build succeeded, 0 errors/warnings.
+
+- [ ] **Step 2: Run the full relevant test suites.**
+
+Run:
+```bash
+dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj -c Release
+dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release
+dotnet test tests/ClaudeDo.Localization.Tests/ClaudeDo.Localization.Tests.csproj -c Release
+```
+Expected: all PASS.
+
+- [ ] **Step 3: Flag visual verification.** The resolver dialog cannot be opened end-to-end until the integrator wires Layer A/B's `RequestConflictResolution(taskId, target)` → `IslandsShellViewModel.RequestConflictResolutionAsync`. Report this as a visual-verification gap for the user/integrator: open a real conflicting merge, confirm hunks render, Accept buttons populate the merged box, Resolve & continue closes on success, Abort restores the tree.
+
+- [ ] **Step 4: Leave the branch for the orchestrator.** Do NOT push, do NOT merge to main.

+# Layer B — Multi-Worktree Merge Cockpit Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Turn the worktrees-overview modal into a batch-merge cockpit (multi-select N worktrees → one target branch → "Merge all" with skip-and-continue conflict collection), and migrate `WorktreeModalView`'s bespoke inline diff onto the canonical `DiffLinesView`.
+
+**Architecture:** The cockpit VM keeps depending on the concrete `WorkerClient` (the overview/cleanup/state methods live only on `WorkerClient`, not `IWorkerClient`). The batch loop is extracted into a delegate-driven method `MergeSelectedAsync(Func<...> mergeFn)` so it is unit-testable with a fake merge function and a never-connected `WorkerClient`. Clean merges (`Status=="merged"`) update the row; conflicts (`Status=="conflict"`, which `MergeTaskAsync` already auto-aborts) are collected into a `ConflictRows` list whose rows expose a `Resolve` button wired to an inert `RequestConflictResolution(taskId, targetBranch)` seam. The diff migration replaces the right-pane `ItemsControl` in `WorktreeModalView` with `DiffLinesView`, feeding it `DiffLineViewModel`s produced by `UnifiedDiffParser`, and deletes the now-dead `WorktreeDiffLineViewModel`/`WorktreeDiffLineKind`.
+
+**Tech Stack:** .NET 8, Avalonia 12, CommunityToolkit.Mvvm source generators, xUnit. Build UI with `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`; run `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`.
+
+**Frozen contracts reused (do NOT modify):**
+- `WorkerClient.MergeTaskAsync(string taskId, string targetBranch, bool removeWorktree, string commitMessage) -> Task<MergeResultDto>`
+- `WorkerClient.GetMergeTargetsAsync(string taskId) -> Task<MergeTargetsDto?>` (`MergeTargetsDto(string DefaultBranch, IReadOnlyList<string> LocalBranches)`)
+- `MergeResultDto(string Status, IReadOnlyList<string> ConflictFiles, string? ErrorMessage)` — `Status` is `"merged" | "conflict" | "blocked" | <other>`
+- `WorkerClient.GetWorktreesOverviewAsync`, `CleanupFinishedWorktreesAsync`, `SetWorktreeStateAsync`, `ForceRemoveWorktreeAsync`
+- `GitService.GetFileDiffAsync(worktreePath, baseCommit?, relativePath)` returns a `git diff` blob including the `diff --git` header (so `UnifiedDiffParser.Parse` handles it)
+- `DiffLinesView` (`Lines` styled property, `IEnumerable?`), `DiffLineViewModel`, `DiffFileViewModel`, `UnifiedDiffParser.Parse` / `.Flatten`
+
+**Do NOT touch:** any worker-side files (`WorkerHub`, `TaskMergeService`, `GitService`), `IWorkerClient.cs` / `WorkerClient.cs`, `WorkConsole.axaml`, `DetailsIslandViewModel.cs`, and do not create any `ConflictResolver` UI or reference any `ConflictResolver` type.
+
+---
+
+## File Structure
+
+- `src/ClaudeDo.Ui/ViewModels/Modals/WorktreesOverviewModalViewModel.cs` — **modify.** Add `BatchMergeOutcome` enum; add `IsChecked`/`MergeOutcome` (+ derived) to the row VM; add `MergeTargets`, `SelectedTarget`, `SelectedCount`, `IsMerging`, `BatchProgress`, `ConflictRows`, the `RequestConflictResolution` seam, `MergeSelectedAsync`, `MergeAllCommand`, `ResolveConflictCommand`, `ToggleSelectAllCommand`, target loading, and per-row check subscription. Keep all existing context-menu commands/wiring intact.
+- `src/ClaudeDo.Ui/Views/Modals/WorktreesOverviewModalView.axaml` — **modify.** Add a per-row checkbox + outcome badge, a target `ComboBox` + "Merge all" button + progress text in the toolbar, and a "Needs resolution" panel listing `ConflictRows` with `Resolve` buttons.
+- `src/ClaudeDo.Ui/ViewModels/Modals/WorktreeModalViewModel.cs` — **modify.** Replace `SelectedFileDiffLines` element type with `DiffLineViewModel` produced via `UnifiedDiffParser`; delete `WorktreeDiffLineKind` and `WorktreeDiffLineViewModel`.
+- `src/ClaudeDo.Ui/Views/Modals/WorktreeModalView.axaml` — **modify.** Replace the right-pane `ItemsControl` with `ctl:DiffLinesView`; drop the `DiffLineKindToBrushConverter` resource.
+- `src/ClaudeDo.Localization/locales/en.json` + `de.json` — **modify.** Add new `modals.worktreesOverview.*` and `vm.worktreesOverview.*` keys (keep parity).
+- `tests/ClaudeDo.Ui.Tests/ViewModels/WorktreesOverviewBatchMergeTests.cs` — **create.** Unit tests for `MergeSelectedAsync` skip-and-continue, conflict collection, progress, selection gating, and the resolve seam.
+
+No `IWorkerClient` change → no test-fake updates needed.
+
+---
+
+## Task 1: Row-level batch state (outcome enum + row VM fields)
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Modals/WorktreesOverviewModalViewModel.cs`
+- Test: `tests/ClaudeDo.Ui.Tests/ViewModels/WorktreesOverviewBatchMergeTests.cs`
+
+- [ ] **Step 1: Write the failing test**
+
+Create `tests/ClaudeDo.Ui.Tests/ViewModels/WorktreesOverviewBatchMergeTests.cs`:
+
+```csharp
+using ClaudeDo.Data.Models;
+using ClaudeDo.Ui.ViewModels.Modals;
+using TaskStatus = ClaudeDo.Data.Models.TaskStatus;
+using Xunit;
+
+namespace ClaudeDo.Ui.Tests.ViewModels;
+
+public class WorktreesOverviewBatchMergeTests
+{
+    private static WorktreeOverviewRowViewModel ActiveRow(string id) => new()
+    {
+        TaskId = id,
+        TaskTitle = $"Task {id}",
+        TaskStatus = TaskStatus.WaitingForReview,
+        State = WorktreeState.Active,
+    };
+
+    [Fact]
+    public void Row_outcome_helpers_reflect_state()
+    {
+        var row = ActiveRow("a");
+        Assert.Equal(BatchMergeOutcome.None, row.MergeOutcome);
+        Assert.False(row.IsConflict);
+
+        row.MergeOutcome = BatchMergeOutcome.Conflict;
+        Assert.True(row.IsConflict);
+
+        row.MergeOutcome = BatchMergeOutcome.Merged;
+        Assert.False(row.IsConflict);
+    }
+}
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter WorktreesOverviewBatchMergeTests`
+Expected: FAIL — `BatchMergeOutcome` and `MergeOutcome`/`IsConflict` do not exist (compile error).
+
+- [ ] **Step 3: Add the enum and row fields**
+
+In `WorktreesOverviewModalViewModel.cs`, add the enum just above `WorktreeOverviewRowViewModel`:
+
+```csharp
+public enum BatchMergeOutcome { None, Merging, Merged, Conflict, Blocked, Failed }
+```
+
+Inside `WorktreeOverviewRowViewModel`, add after the existing `_isSelected` field:
+
+```csharp
+    [ObservableProperty] private bool _isChecked;
+    [ObservableProperty]
+    [NotifyPropertyChangedFor(nameof(IsConflict))]
+    [NotifyPropertyChangedFor(nameof(HasOutcome))]
+    private BatchMergeOutcome _mergeOutcome;
+
+    public bool IsConflict => MergeOutcome == BatchMergeOutcome.Conflict;
+    public bool HasOutcome => MergeOutcome != BatchMergeOutcome.None;
+```
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter WorktreesOverviewBatchMergeTests`
+Expected: PASS (1 test).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Modals/WorktreesOverviewModalViewModel.cs tests/ClaudeDo.Ui.Tests/ViewModels/WorktreesOverviewBatchMergeTests.cs
+git commit -m "feat(ui): add batch-merge row state to worktrees cockpit VM"
+```
+

+
+## Task 2: Batch orchestration (`MergeSelectedAsync` skip-and-continue)
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Modals/WorktreesOverviewModalViewModel.cs`
+- Test: `tests/ClaudeDo.Ui.Tests/ViewModels/WorktreesOverviewBatchMergeTests.cs`
+
+- [ ] **Step 1: Write the failing tests**
+
+Append to `WorktreesOverviewBatchMergeTests.cs`. The helper builds a VM with a never-connected `WorkerClient` (the loop never touches it) and seeds `Rows` directly:

+- [ ] **Step 2: Run tests to verify they fail**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter WorktreesOverviewBatchMergeTests`
+Expected: FAIL — `MergeSelectedAsync`, `ConflictRows`, `IsMerging`, `SelectedTarget` do not exist (compile error).
+
+- [ ] **Step 3: Implement the orchestration + cockpit fields**
+
+In `WorktreesOverviewModalViewModel.cs`, add these `using`s if missing: `using ClaudeDo.Ui.Services;` (already present). Add fields/properties to `WorktreesOverviewModalViewModel` (after the existing `_selectedRow` field):
+
+```csharp
+    [ObservableProperty][NotifyCanExecuteChangedFor(nameof(MergeAllCommand))] private string? _selectedTarget;
+    [ObservableProperty][NotifyCanExecuteChangedFor(nameof(MergeAllCommand))] private int _selectedCount;
+    [ObservableProperty][NotifyCanExecuteChangedFor(nameof(MergeAllCommand))] private bool _isMerging;
+    [ObservableProperty] private string? _batchProgress;
+
+    public ObservableCollection<string> MergeTargets { get; } = new();
+    public ObservableCollection<WorktreeOverviewRowViewModel> ConflictRows { get; } = new();
+
+    /// Inert seam wired by the integrator to Layer C's resolver at merge time. (taskId, targetBranch)
+    public Func<string, string, Task>? RequestConflictResolution { get; set; }
+```
+
+Add a helper to enumerate rows regardless of grouped/flat mode, plus the orchestration method:
+
+```csharp
+    public IEnumerable<WorktreeOverviewRowViewModel> AllRows =>
+        IsGlobal ? Groups.SelectMany(g => g.Rows) : Rows;
+
+    public async Task MergeSelectedAsync(
+        Func<string, string, bool, string, Task<MergeResultDto>> mergeFn,
+        CancellationToken ct = default)
+    {
+        var target = SelectedTarget;
+        if (string.IsNullOrWhiteSpace(target)) return;
+
+        var selected = AllRows.Where(r => r.IsChecked && r.IsActive).ToList();
+        if (selected.Count == 0) return;
+
+        IsMerging = true;
+        ConflictRows.Clear();
+        var done = 0;
+        try
+        {
+            foreach (var row in selected)
+            {
+                ct.ThrowIfCancellationRequested();
+                row.MergeOutcome = BatchMergeOutcome.Merging;
+                BatchProgress = Loc.T("vm.worktreesOverview.batchProgress", ++done, selected.Count);
+
+                MergeResultDto result;
+                try
+                {
+                    result = await mergeFn(row.TaskId, target!, false,
+                        Loc.T("vm.merge.commitMessage", row.TaskTitle));
+                }
+                catch
+                {
+                    row.MergeOutcome = BatchMergeOutcome.Failed;
+                    continue;
+                }
+
+                switch (result.Status)
+                {

+                        row.MergeOutcome = BatchMergeOutcome.Blocked;
+                        break;
+                    default:
+                        row.MergeOutcome = BatchMergeOutcome.Failed;
+                        break;
+                }
+            }
+            BatchProgress = Loc.T("vm.worktreesOverview.batchDone",
+                selected.Count(r => r.MergeOutcome == BatchMergeOutcome.Merged), ConflictRows.Count);

+        finally
+        {
+            IsMerging = false;
+        }
+    }

+
+- [ ] **Step 2: Run tests to verify they fail**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter WorktreesOverviewBatchMergeTests`
+Expected: FAIL — `AddRowForTest`, `ResolveConflictCommand`, `MergeAllCommand` do not exist (compile error).
+
+- [ ] **Step 3: Implement subscription, commands, target loading**
+
+In `WorktreesOverviewModalViewModel.cs`:
+
+(a) Add a row-hook that recomputes `SelectedCount` when a row's `IsChecked` changes, and a test seam to add a hooked row. Add these methods to the class:
+
+```csharp
+    private void HookRow(WorktreeOverviewRowViewModel row)
+    {
+        row.PropertyChanged += (_, e) =>
+        {
+            if (e.PropertyName is nameof(WorktreeOverviewRowViewModel.IsChecked)
+                               or nameof(WorktreeOverviewRowViewModel.State))
+                RecomputeSelected();
+        };
+    }
+
+    private void RecomputeSelected() =>
+        SelectedCount = AllRows.Count(r => r.IsChecked && r.IsActive);
+
+    // Test seam: adds a row to the flat list with selection tracking wired up.
+    internal void AddRowForTest(WorktreeOverviewRowViewModel row)
+    {
+        HookRow(row);
+        Rows.Add(row);
+    }
+```
+
+(b) In `LoadAsync`, call `HookRow(row)` everywhere a row is added. Replace the two add sites:
+
+In the grouped branch, change `foreach (var row in grp) group.Rows.Add(row);` to:
+
+```csharp
+                    foreach (var row in grp) { HookRow(row); group.Rows.Add(row); }
+```
+
+In the flat branch, change `foreach (var row in ordered) Rows.Add(row);` to:
+
+```csharp
+                foreach (var row in ordered) { HookRow(row); Rows.Add(row); }
+```
+
+Also, at the start of `LoadAsync` after `IsBusy = true;`, reset batch UI state and (re)load merge targets at the end of the `try`:
+
+After `Rows.Clear(); Groups.Clear();` add:
+
+```csharp
+            ConflictRows.Clear();
+            SelectedCount = 0;
+            BatchProgress = null;
+```
+
+At the very end of the `try` block (after the if/else that fills rows/groups) add:
+
+```csharp
+            await LoadMergeTargetsAsync();
+```
+
+(c) Add target loading. The branch list is repo-level, so query it from the first active row:
+
+```csharp
+    private async Task LoadMergeTargetsAsync()
+    {
+        var anchor = AllRows.FirstOrDefault(r => r.IsActive);
+        if (anchor is null) { MergeTargets.Clear(); SelectedTarget = null; return; }
+        try
+        {
+            var targets = await _worker.GetMergeTargetsAsync(anchor.TaskId);
+            MergeTargets.Clear();
+            if (targets is null) { SelectedTarget = null; return; }
+            foreach (var b in targets.LocalBranches) MergeTargets.Add(b);
+            SelectedTarget = MergeTargets.Contains(targets.DefaultBranch)
+                ? targets.DefaultBranch
+                : MergeTargets.FirstOrDefault();
+        }
+        catch { MergeTargets.Clear(); SelectedTarget = null; }
+    }
+```
+
+(d) Add the commands:
+
+```csharp
+    private bool CanMergeAll() => !IsMerging && SelectedCount > 0 && !string.IsNullOrWhiteSpace(SelectedTarget);
+
+    [RelayCommand(CanExecute = nameof(CanMergeAll))]
+    private Task MergeAll() => MergeSelectedAsync(_worker.MergeTaskAsync);
+
+    [RelayCommand]
+    private void ResolveConflict(WorktreeOverviewRowViewModel? row)
+    {
+        if (row is null) return;
+        RequestConflictResolution?.Invoke(row.TaskId, SelectedTarget ?? "");
+    }
+
+    [RelayCommand]
+    private void ToggleSelectAll()
+    {
+        var actives = AllRows.Where(r => r.IsActive).ToList();
+        var allChecked = actives.Count > 0 && actives.All(r => r.IsChecked);
+        foreach (var r in actives) r.IsChecked = !allChecked;
+    }
+```
+

+## Task 4: Cockpit view — checkboxes, target picker, Merge all, conflicts panel
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Modals/WorktreesOverviewModalView.axaml`
+
+This task is AXAML only (no logic) → no new unit test; flag for visual verification.
+
+- [ ] **Step 1: Add the batch toolbar controls**
+
+In `WorktreesOverviewModalView.axaml`, replace the toolbar `StackPanel` (currently containing Refresh, Cleanup finished, StatusMessage) with one that adds select-all, the target picker, the Merge-all button and progress text. Replace the inner `<StackPanel Orientation="Horizontal" Spacing="8">...</StackPanel>` of the toolbar `Border` with:
+
+```xml
+        <StackPanel Orientation="Horizontal" Spacing="8">
+          <Button Classes="btn" Content="{loc:Tr modals.worktreesOverview.refresh}" Command="{Binding RefreshCommand}" IsEnabled="{Binding !IsBusy}"/>
+          <Button Classes="btn" Content="{loc:Tr modals.worktreesOverview.cleanupFinished}" Command="{Binding CleanupFinishedCommand}" IsEnabled="{Binding !IsBusy}"/>
+          <Button Classes="btn" Content="{loc:Tr modals.worktreesOverview.selectAll}" Command="{Binding ToggleSelectAllCommand}"/>
+          <Border Width="1" Background="{DynamicResource LineBrush}" Margin="4,2"/>
+          <TextBlock Text="{loc:Tr modals.worktreesOverview.targetLabel}" VerticalAlignment="Center" Foreground="{DynamicResource TextDimBrush}"/>
+          <ComboBox MinWidth="160"
+                    ItemsSource="{Binding MergeTargets}"
+                    SelectedItem="{Binding SelectedTarget, Mode=TwoWay}"/>
+          <Button Classes="btn accent"
+                  Content="{loc:Tr modals.worktreesOverview.mergeAll}"
+                  Command="{Binding MergeAllCommand}"/>
+          <TextBlock Text="{Binding SelectedCount, StringFormat='{}{0} selected'}"
+                     VerticalAlignment="Center" Foreground="{DynamicResource TextDimBrush}"/>
+          <TextBlock Text="{Binding BatchProgress}" VerticalAlignment="Center" Margin="8,0,0,0"
+                     Foreground="{DynamicResource TextDimBrush}"/>
+          <TextBlock Text="{Binding StatusMessage}" VerticalAlignment="Center" Margin="8,0,0,0"
+                     Foreground="{DynamicResource TextDimBrush}"/>
+        </StackPanel>
+```
+
+- [ ] **Step 2: Add a checkbox + outcome badge to the row template**
+
+In the `WorktreeRowTemplate` `DataTemplate`, change the row `Grid` to add a leading checkbox column and a trailing outcome column. Replace the `<Grid ColumnDefinitions="*,90,80,80">...</Grid>` (the whole grid, lines for Task/State/Diff/Age) with:
+
+```xml
+        <Grid ColumnDefinitions="Auto,*,90,90,80,80">
+          <CheckBox Grid.Column="0" VerticalAlignment="Center" Margin="0,0,8,0"
+                    IsChecked="{Binding IsChecked, Mode=TwoWay}"
+                    IsEnabled="{Binding IsActive}"
+                    IsVisible="{Binding IsActive}"/>
+          <StackPanel Grid.Column="1" Orientation="Vertical" Spacing="2">
+            <TextBlock Classes="title" Text="{Binding TaskTitle}"/>
+            <StackPanel Orientation="Horizontal" Spacing="4">
+              <TextBlock Classes="meta" Text="{Binding TaskStatus}"/>
+              <TextBlock Classes="meta" Text="•"
+                         IsVisible="{Binding !PathExistsOnDisk}"/>
+              <TextBlock Classes="meta" Text="{loc:Tr modals.worktreesOverview.phantom}" Foreground="{DynamicResource StatusErrorBrush}"
+                         IsVisible="{Binding !PathExistsOnDisk}"
+                         ToolTip.Tip="{loc:Tr modals.worktreesOverview.phantomTooltip}"/>
+            </StackPanel>
+          </StackPanel>
+          <TextBlock Grid.Column="2" Classes="meta" VerticalAlignment="Center"
+                     Text="{Binding MergeOutcome}"
+                     IsVisible="{Binding HasOutcome}"/>
+          <Border Grid.Column="3" CornerRadius="3" Padding="6,2" VerticalAlignment="Center"
+                  Background="{Binding State, Converter={StaticResource WorktreeStateColor}}">
+            <TextBlock Classes="meta" Text="{Binding State}" Foreground="{DynamicResource TextBrush}"
+                       HorizontalAlignment="Center"/>
+          </Border>
+          <TextBlock Grid.Column="4" Classes="meta" Text="{Binding DiffStat}" VerticalAlignment="Center"/>
+          <TextBlock Grid.Column="5" Classes="meta" Text="{Binding AgeText}" VerticalAlignment="Center"/>
+        </Grid>
+```
+
+Then update the column-header `Grid` (the one with `ColumnDefinitions="*,90,80,80"` near the ScrollViewer top) to match the new column layout:
+
+```xml
+          <Grid ColumnDefinitions="Auto,*,90,90,80,80" Margin="12,0,12,4">
+            <TextBlock Grid.Column="1" Classes="eyebrow" Text="{loc:Tr modals.worktreesOverview.columnTask}"/>
+            <TextBlock Grid.Column="2" Classes="eyebrow" Text="{loc:Tr modals.worktreesOverview.columnOutcome}"/>
+            <TextBlock Grid.Column="3" Classes="eyebrow" Text="{loc:Tr modals.worktreesOverview.columnState}"/>
+            <TextBlock Grid.Column="4" Classes="eyebrow" Text="{loc:Tr modals.worktreesOverview.columnDiff}"/>
+            <TextBlock Grid.Column="5" Classes="eyebrow" Text="{loc:Tr modals.worktreesOverview.columnAge}"/>
+          </Grid>
+```
+
+- [ ] **Step 3: Add the "Needs resolution" panel**
+
+Inside the content `ScrollViewer`'s root `StackPanel`, at the very top (before the column-header `Grid`), add a conflicts panel that only shows when there are conflicts:
+
+```xml
+          <Border IsVisible="{Binding ConflictRows.Count}"
+                  Background="{DynamicResource ErrorTintBrush}"
+                  BorderBrush="{DynamicResource StatusErrorBrush}"
+                  BorderThickness="1" CornerRadius="6" Padding="12,8" Margin="0,0,0,12">
+            <StackPanel Spacing="6">
+              <TextBlock Classes="eyebrow" Text="{loc:Tr modals.worktreesOverview.needsResolution}"/>
+              <ItemsControl ItemsSource="{Binding ConflictRows}">
+                <ItemsControl.ItemTemplate>
+                  <DataTemplate x:DataType="vm:WorktreeOverviewRowViewModel">
+                    <Grid ColumnDefinitions="*,Auto" Margin="0,2">
+                      <TextBlock Grid.Column="0" Classes="meta" VerticalAlignment="Center"
+                                 Text="{Binding TaskTitle}"/>
+                      <Button Grid.Column="1" Classes="btn"
+                              Content="{loc:Tr modals.worktreesOverview.resolve}"
+                              Command="{Binding $parent[Window].((vm:WorktreesOverviewModalViewModel)DataContext).ResolveConflictCommand}"
+                              CommandParameter="{Binding}"/>
+                    </Grid>
+                  </DataTemplate>
+                </ItemsControl.ItemTemplate>
+              </ItemsControl>
+            </StackPanel>
+          </Border>
+```
+
+> `IsVisible="{Binding ConflictRows.Count}"` uses Avalonia's int→bool coercion (0 = false). If the build flags this, change to a value converter already present, but int→bool is supported.

+## Task 6: Migrate `WorktreeModalView` diff onto `DiffLinesView`
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Modals/WorktreeModalViewModel.cs`
+- Modify: `src/ClaudeDo.Ui/Views/Modals/WorktreeModalView.axaml`
+
+- [ ] **Step 1: Switch the VM to the canonical diff model**
+
+In `WorktreeModalViewModel.cs`:
+
+(a) Delete the now-dead types at the top of the file:
+
+```csharp
+public enum WorktreeDiffLineKind { Header, Hunk, Added, Removed, Context }
+
+public sealed partial class WorktreeDiffLineViewModel : ViewModelBase
+{
+    public required string Text { get; init; }
+    public required WorktreeDiffLineKind Kind { get; init; }
+}
+```
+
+(b) Change the collection declaration from:
+
+```csharp
+    public ObservableCollection<WorktreeDiffLineViewModel> SelectedFileDiffLines { get; } = new();
+```
+
+to:
+
+```csharp
+    public ObservableCollection<DiffLineViewModel> SelectedFileDiffLines { get; } = new();
+```
+
+(c) Replace the body of `LoadFileDiffAsync` (the `foreach (var line in diff.Split('\n'))` block) so it parses via `UnifiedDiffParser`. The method becomes:
+
+```csharp
+    private async Task LoadFileDiffAsync(WorktreeNodeViewModel? node)
+    {
+        SelectedFileDiffLines.Clear();
+
+        if (node is null || node.IsDirectory || string.IsNullOrEmpty(node.RelativePath))
+            return;
+
+        string diff;
+        try
+        {
+            diff = await _git.GetFileDiffAsync(WorktreePath, BaseCommit, node.RelativePath);
+        }
+        catch
+        {
+            return;
+        }
+
+        foreach (var line in UnifiedDiffParser.Flatten(UnifiedDiffParser.Parse(diff)))
+            SelectedFileDiffLines.Add(line);
+    }
+```
+
+(`DiffLineViewModel`, `DiffFileViewModel`, and `UnifiedDiffParser` are all in the same `ClaudeDo.Ui.ViewModels.Modals` namespace, so no new `using` is required.)
+
+- [ ] **Step 2: Build to confirm the VM compiles and nothing else referenced the deleted types**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: Build succeeded. (If a compile error names `WorktreeDiffLineViewModel`/`WorktreeDiffLineKind` outside this file or the view, that reference must be migrated too — there should be none besides `WorktreeModalView.axaml`, handled next.)
+
+- [ ] **Step 3: Swap the view's inline diff for `DiffLinesView`**
+
+In `WorktreeModalView.axaml`:
+
+(a) Remove the now-unused converter resource. Delete:
+
+```xml
+  <Window.Resources>
+    <converters:DiffLineKindToBrushConverter x:Key="DiffLineKindToBrush"/>
+  </Window.Resources>
+```
+
+(b) Replace the right-pane `ScrollViewer`'s `ItemsControl` (the `SelectableTextBlock` template bound to `SelectedFileDiffLines`) with the canonical control. Replace:
+
+```xml
+          <ItemsControl ItemsSource="{Binding SelectedFileDiffLines}">
+            <ItemsControl.ItemTemplate>
+              <DataTemplate DataType="vm:WorktreeDiffLineViewModel">
+                <SelectableTextBlock Text="{Binding Text}"
+                                     FontFamily="{DynamicResource MonoFont}"
+                                     FontSize="{StaticResource FontSizeMono}"
+                                     Foreground="{Binding Kind, Converter={StaticResource DiffLineKindToBrush}}"
+                                     TextWrapping="NoWrap"/>
+              </DataTemplate>
+            </ItemsControl.ItemTemplate>
+          </ItemsControl>
+```
+
+with:
+
+```xml
+          <ctl:DiffLinesView Lines="{Binding SelectedFileDiffLines}"/>
+```
+
+(The `xmlns:ctl="using:ClaudeDo.Ui.Views.Controls"` namespace is already declared at the top of this file.)
+
+- [ ] **Step 4: Build the app to verify the AXAML compiles**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: Build succeeded.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Modals/WorktreeModalViewModel.cs src/ClaudeDo.Ui/Views/Modals/WorktreeModalView.axaml
+git commit -m "refactor(ui): render worktree modal diff via canonical DiffLinesView"
+```
+
+---
+
+## Task 7: Full build + test sweep
+
+**Files:** none (verification only).
+
+- [ ] **Step 1: Build the whole app**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 2: Run the UI + localization test projects**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`
+Then: `dotnet test tests/ClaudeDo.Localization.Tests/ClaudeDo.Localization.Tests.csproj -c Release`
+Expected: PASS (all green, including the 8 new batch-merge tests).
+
+- [ ] **Step 3: Flag visual-verification gaps**
+
+The cockpit toolbar/checkbox/conflicts-panel layout and the migrated `WorktreeModalView` diff rendering are AXAML changes that cannot be verified headlessly. Report to the user that these need a visual pass (run the app, open the worktrees overview, select several worktrees, pick a target, "Merge all", and open a worktree diff).
+
+---
+
+## Self-Review Notes
+
+- **Spec coverage:** batch-merge cockpit (Tasks 1–4), skip-and-continue + conflict collection (Task 2), single target picker (Tasks 3–4), Resolve → `RequestConflictResolution(taskId, targetBranch)` seam left unwired (Tasks 3–4), `WorktreeModalView` diff migration to `DiffLinesView` (Task 6), no worker files touched, no `IWorkerClient` change, locales in parity (Task 5). ✔
+- **No ConflictResolver reference:** the seam is a bare `Func<string,string,Task>?`; no Layer C type is named. ✔
+- **Type consistency:** `BatchMergeOutcome`, `MergeOutcome`, `IsConflict`, `HasOutcome`, `MergeSelectedAsync`, `ConflictRows`, `SelectedTarget`, `SelectedCount`, `IsMerging`, `BatchProgress`, `RequestConflictResolution`, `MergeAllCommand`, `ResolveConflictCommand`, `ToggleSelectAllCommand`, `AddRowForTest`, `AllRows` are used consistently across tasks. ✔

+# Terminal-style Review Controls Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Move review feedback into the Output (terminal) tab as a prompt-style input with `[Retry]`/`[Reset]` actions, and relocate Approve + all merge/worktree controls to a new **Git** tab.
+
+**Architecture:** Pure UI-layer change in `ClaudeDo.Ui`. Add an `IsGitTab` computed flag to `DetailsIslandViewModel`, re-home existing XAML blocks across three tabs (Output · Git · Session) in `WorkConsole.axaml`, add a bottom-docked review footer to the Output tab, and intercept Enter in `WorkConsole.axaml.cs`. No worker-side or `IWorkerClient` changes; no ViewModel command renames.
+
+**Tech Stack:** .NET 8, Avalonia 12 (Fluent), CommunityToolkit.Mvvm, xUnit (ClaudeDo.Ui.Tests).
+
+**Reference spec:** `docs/superpowers/specs/2026-06-05-terminal-review-design.md`
+
+**Build/test note (from CLAUDE.md):** A running Worker locks `Debug` output — build UI in `-c Release`:

+
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs` — add `IsGitTab`, wire notifications.
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml` — add Git tab button; split tab bodies; add Output-tab review footer; update Session empty-state text.
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml.cs` — Enter-to-Retry key handling.
+- Test: `tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandTabsTests.cs` (create) — `IsGitTab` behavior.

+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs:139-147`
+- Test: `tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandTabsTests.cs` (create)

+- [ ] **Step 1: Write the failing test**
+
+Create `tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandTabsTests.cs`. Mirror the
+construction pattern from `DetailsIslandPrepModeTests.cs` (temp SQLite db,
+`TestDbFactory`, `StubWorkerClient`, `NullServiceProvider`, `StubNotesApi`).

+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter DetailsIslandTabsTests`
+Expected: FAIL — compile error, `DetailsIslandViewModel` has no `IsGitTab`.
+
+- [ ] **Step 3: Add `IsGitTab` to the ViewModel**
+
+In `DetailsIslandViewModel.cs`, find the `SelectedTab` property notifications and the
+tab getters (around lines 139-147). Add the `IsGitTab` notification and getter:
+
+```csharp
+    [NotifyPropertyChangedFor(nameof(IsOutputTab))]
+    [NotifyPropertyChangedFor(nameof(IsSessionTab))]
+    [NotifyPropertyChangedFor(nameof(IsGitTab))]
+```
+
+```csharp
+    public bool IsOutputTab  => SelectedTab == "output";
+    public bool IsGitTab     => SelectedTab == "git";
+    public bool IsSessionTab => SelectedTab == "session";
+```
+
+(Leave `SelectTab` unchanged — it already accepts any string and defaults to `"output"`.)
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release --filter DetailsIslandTabsTests`
+Expected: PASS (2 tests).
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs tests/ClaudeDo.Ui.Tests/ViewModels/DetailsIslandTabsTests.cs
+git commit -m "feat(ui): add IsGitTab flag to work console view model"

+
+### Task 2: Add the Git tab button and move the merge/worktree block onto it
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml:124-135` (tab strip)
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml:164-273` (tab body)
+
+- [ ] **Step 1: Add the Git tab button**
+
+In the tab strip `StackPanel` (lines 124-135), insert a Git button between the Output
+and Session buttons:
+
+```xml
+        <StackPanel Orientation="Horizontal">
+          <Button Classes="tab-btn"
+                  Classes.active="{Binding IsOutputTab}"
+                  Content="Output"
+                  Command="{Binding SelectTabCommand}"
+                  CommandParameter="output" />
+          <Button Classes="tab-btn"
+                  Classes.active="{Binding IsGitTab}"
+                  Content="Git"
+                  Command="{Binding SelectTabCommand}"
+                  CommandParameter="git" />
+          <Button Classes="tab-btn"

+                  CommandParameter="session" />
+        </StackPanel>
+```
+
+- [ ] **Step 2: Move the "Merge & worktree" block to a new Git-tab ScrollViewer**
+
+In the tab body `Grid` (starts line 139), the body currently holds the Output
+`ScrollViewer` (`IsVisible="{Binding IsOutputTab}"`, lines 142-162) and the Session
+`ScrollViewer` (`IsVisible="{Binding IsSessionTab}"`, lines 165-273).
+
+Cut the **entire "Merge & worktree management" `StackPanel`** — the block currently at
+lines 195-241, beginning with the comment `<!-- Merge & worktree management -->` and the
+`<StackPanel Spacing="10" IsVisible="{Binding ShowMergeSection}">` and ending at its
+matching `</StackPanel>` after the `MergeAllError` `TextBlock` (line 241).
+
+Add a new Git-tab `ScrollViewer` between the Output and Session `ScrollViewer`s, and
+paste the cut block inside it:
+
+```xml
+        <!-- Git: merge target, approve, diff, worktree -->
+        <ScrollViewer IsVisible="{Binding IsGitTab}" Padding="14,10">
+          <StackPanel Spacing="14">

+                      Command="{Binding ApproveReviewCommand}" />
+            </StackPanel>
+
+            <!-- Merge & worktree management (moved from Session tab) -->

+            </StackPanel>
+
+          </StackPanel>
+        </ScrollViewer>
+```
+
+- [ ] **Step 3: Remove the old review block from the Session tab**
+
+In the Session `ScrollViewer` (`IsVisible="{Binding IsSessionTab}"`), delete the
+**"Review controls" `StackPanel`** currently at lines 168-193 (the
+`<!-- Review controls -->` comment, the `<StackPanel Spacing="8" IsVisible="{Binding IsWaitingForReview}">`,
+the REVIEW label, Feedback label, the `ReviewFeedback` TextBox, and the four buttons).
+After this and Step 2, the Session tab's `StackPanel` should contain only the Child
+outcomes block (lines 244-263) and the empty-state `TextBlock` (lines 266-270).
+
+- [ ] **Step 4: Build and verify it compiles**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 5: Commit**
+
+```bash

+### Task 3: Add the prompt-style review footer to the Output tab
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml` (Output-tab area + the `Grid` body)
+
+- [ ] **Step 1: Restructure the Output tab body to dock a footer below the log**
+
+The body `Grid` (line 139) overlays all three tab `ScrollViewer`s. Replace the Output
+`ScrollViewer` (lines 142-162) with a `DockPanel` that keeps the log filling and docks
+the review footer at the bottom. Keep `Name="LogScroll"` on the `ScrollViewer` (the
+code-behind references it). Use this exact markup:
+
+```xml
+        <!-- Output: log + review footer, both gated on IsOutputTab -->
+        <DockPanel IsVisible="{Binding IsOutputTab}" LastChildFill="True">
+

+### Task 4: Enter-to-Retry key handling
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml.cs`
+
+- [ ] **Step 1: Add the KeyDown handler**
+
+In `WorkConsole.axaml.cs`, add `using Avalonia.Input;` at the top. Add a handler that
+runs `RejectReviewCommand` on Enter (without Shift) and lets Shift+Enter insert a
+newline. Wire it from the `ReviewInput` TextBox. Full file:
+
+```csharp
+using System;
+using System.Collections.Specialized;
+using Avalonia.Controls;
+using Avalonia.Input;
+using ClaudeDo.Ui.ViewModels.Islands;
+
+namespace ClaudeDo.Ui.Views.Islands.Detail;

+{
+    private INotifyCollectionChanged? _log;
+
+    public WorkConsole()
+    {
+        InitializeComponent();
+        DataContextChanged += OnDataContextChanged;
+    }
+
+    private void OnDataContextChanged(object? sender, EventArgs e)
+    {
+        if (_log is not null)
+            _log.CollectionChanged -= OnLogChanged;
+
+        _log = (DataContext as DetailsIslandViewModel)?.Log;
+
+        if (_log is not null)
+            _log.CollectionChanged += OnLogChanged;
+    }
+
+    private void OnLogChanged(object? sender, NotifyCollectionChangedEventArgs e)
+    {
+        if (e.Action != NotifyCollectionChangedAction.Add) return;
+        EventHandler? handler = null;
+        handler = (_, _) =>
+        {
+            LogScroll.LayoutUpdated -= handler;
+            LogScroll.ScrollToEnd();

+    }
+

+    {
+        if (e.Key != Key.Enter || e.KeyModifiers.HasFlag(KeyModifiers.Shift))
+            return;
+
+        if (DataContext is DetailsIslandViewModel vm &&
+            vm.RejectReviewCommand.CanExecute(null))
+        {
+            vm.RejectReviewCommand.Execute(null);
+        }
+
+        e.Handled = true;
+    }
+}
+```
+
+- [ ] **Step 2: Wire the handler in XAML**
+
+On the `ReviewInput` TextBox added in Task 3, add the event hookup attribute:
+
+```xml
+              <TextBox Name="ReviewInput"
+                       KeyDown="OnReviewInputKeyDown"
+                       Text="{Binding ReviewFeedback, Mode=TwoWay}"

+### Task 5: Update the Session empty-state copy
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml` (empty-state `TextBlock`, was line 266-270)
+
+- [ ] **Step 1: Reword the empty-state text**
+
+The Session empty-state still says review/merge controls appear there. Replace its
+`Text` so it reflects that those moved:
+
+```xml
+            <TextBlock IsVisible="{Binding ShowSessionEmpty}"
+                       Classes="meta"

+                       Text="Nothing to manage yet — subtask outcomes appear here once the run finishes. Review in the Output tab, merge in the Git tab." />

+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj -c Release`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/Islands/Detail/WorkConsole.axaml
+git commit -m "docs(ui): reword Session empty-state for relocated review/merge controls"
+```

+
+### Task 6: Final verification
+
+- [ ] **Step 1: Run the full UI test project**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj -c Release`
+Expected: all tests PASS.
+
+- [ ] **Step 2: Manual visual verification (cannot be auto-verified — flag to user)**
+
+Launch the app with a task in `WaitingForReview` and confirm:
+- Output tab shows the prompt footer (`❯` + input + `[Retry]` `[Reset]`) only while awaiting review; it is hidden otherwise.
+- Typing + **Enter** sends Retry (requeues with feedback); **Shift+Enter** inserts a newline; **Enter on empty input** does nothing.
+- `[Reset]` parks the task to Idle.
+- Git tab shows **Approve** + merge target + Open Diff / Merge / Worktree / Review Combined Diff / Merge All Subtasks.
+- Session tab shows only subtask outcomes / the reworded empty state.
+- Tab switching highlights the active tab correctly (Output ↔ Git ↔ Session).

+# Plan — Unify the parent-task model
+
+Spec: `docs/superpowers/specs/2026-06-09-unify-parent-task-model-design.md`
+
+Subagents: `sonnet`. Stage files explicitly by path (never `git add -A`). TDD.
+Build with `-c Release` per project. Commit per task (Conventional Commits).
+
+## Task 1 — Single parent-advance path
+
+- Rename `TaskStateService.TryAdvanceImprovementParentAsync` → `TryAdvanceParentAsync`.
+- Make it advance **any** `WaitingForChildren` parent → `WaitingForReview` when all
+  children are terminal, and advance a parent with **zero** children straight to
+  `WaitingForReview`.
+- In `OnChildTerminalAsync`: drop the `TryCompleteParentAsync` call; keep
+  `_chain.OnChildFinishedAsync`; call the renamed advance method for all parents.
+- Tests: extend `WaitingForChildrenLifecycleTests` — (a) improvement parent still
+  advances; (b) a `WaitingForChildren` parent whose children are a *sequential chain*
+  advances only after the last one is terminal; (c) zero-children parent advances.
+
+## Task 2 — Delete `TryCompleteParentAsync`
+
+- Remove `TaskRepository.TryCompleteParentAsync` (`TaskRepository.cs:477-502`) and
+  any remaining references.
+- Update `src/ClaudeDo.Data/CLAUDE.md` (drop it from the TaskRepository helper list).
+- Build Data + Worker; fix references.
+
+## Task 3 — Planning finalize enters `WaitingForChildren`
+
+- `TaskStateService.FinalizePlanningAsync`: in the same `ExecuteUpdateAsync`, set
+  `Status = WaitingForChildren` alongside `PlanningPhase = Finalized` /
+  `PlanningFinalizedAt`.
+- Verify `PlanningSessionManager.FinalizeAsync` ordering: finalize (→ WaitingForChildren)
+  **before** `SetupChainAsync` enqueues child[0]. Adjust only if ordering is wrong.
+- Tests: finalizing a planning parent with N children leaves it `WaitingForChildren`;
+  after the chain completes it is `WaitingForReview` (not `Done`); a planning parent
+  with zero finalized children lands in `WaitingForReview`.
+
+## Task 4 — Approve merges the whole unit
+
+**Decision: full UX consolidation.** Approve becomes the single entry for reviewing
+*and* merging any task; the separate planning-merge views are folded into the review
+panel. The `PlanningMergeOrchestrator` (which already merges the unit + sets the
+parent `Done` for both planning and improvement, with conflict continue/abort) is
+reused as the engine; only its *entry/UI* moves.
+
+Backend:
+- `WorkerHub.ApproveReview`: for a parent that **has children**, drive
+  `PlanningMergeOrchestrator.StartAsync` (event-based: `PlanningMergeStarted` /
+  `PlanningSubtaskMerged` / `PlanningMergeConflict` / `PlanningMergeAborted` /
+  `PlanningCompleted`) instead of the one-shot `ApproveAndMergeAsync`. Childless tasks
+  keep `ApproveAndMergeAsync`. Conflict resolution still goes through
+  `ContinuePlanningMerge` / `AbortPlanningMerge`.
+- Keep the orchestrator, `ContinuePlanningMerge`, `AbortPlanningMerge`,
+  `GetPlanningAggregate`, `BuildPlanningIntegrationBranch`. Remove the now-redundant
+  standalone `MergeAllPlanning` hub method (approve is the entry).
+- (Optional cleanup) route the orchestrator's `FinalizeParentDoneAsync` through
+  `TaskStateService` so `Status` writes stay centralized; low priority.
+
+UI (Avalonia, MVVM — visual-verification gaps, flag for user):
+- The review panel (`DetailsIslandViewModel` / its view) is the single approve+merge
+  surface. For a child-bearing parent in `WaitingForReview`, approve shows the
+  unit-merge progress + per-subtask state, the aggregate/integration diff preview, and
+  conflict continue/abort — all inline in the review panel.
+- Remove the separate planning-merge view(s)/commands and the standalone "Merge all"
+  button; re-wire their `PlanningMerge*` event handlers into the review panel VM.
+- Sync `IWorkerClient` + hand-rolled test fakes in both UI/Worker test projects.
+
+Tests: approving a parent with two `Done` children merges both then sets `Done`; a
+conflicting second child surfaces the conflict and pauses (continue/abort) without
+losing the parent's `WaitingForReview`/merge state.
+
+## Task 5 — Cancellable `WaitingForChildren` parent
+
+- Add `TaskStatus.WaitingForChildren` to the `CancelAsync` guard.
+- Test: a parent in `WaitingForChildren` can be cancelled.
+
+## Task 6 — Docs
+
+- `src/ClaudeDo.Worker/CLAUDE.md`: add `WaitingForChildren` to the Status table +
+  transition diagram; document the unified parent flow and approve-merges-unit;
+  remove `MergeAllPlanning` from the Hub method list.
+- `src/ClaudeDo.Data/CLAUDE.md`: add `WaitingForChildren` to the TaskEntity status list.
+- Root `CLAUDE.md`: update the "Task status flow" convention line.
+
+## Verify
+
+- `dotnet test` for Worker.Tests + Data.Tests (`-c Release`).
+- UI flows (planning finalize → review → approve-merge; improvement parent;
+  retired MergeAllPlanning button) are **visual-verification gaps** — flag for the
+  user to run the app; do not claim they work from tests alone.

+# Approve = Merge → Done, plus Conflict Preview — Design
+
+**Date:** 2026-06-04
+**Status:** Approved (autonomous — user on break, authorized to continue)
+**Author:** brainstormed from issue "Make merge/diff real"
+
+## Problem
+
+Approving a `WaitingForReview` task flips it straight to `Done`
+(`TaskStateService.ApproveReviewAsync`) and **never merges** its worktree — the
+worktree stays `Active`. The user approved three component tasks expecting them
+to merge; none did. Separately, there is **no way to see whether a task's
+worktree merges cleanly** before acting, and a standalone task has no direct
+**Merge** button (single-task merge is only reachable from inside the Diff
+modal).
+
+What is already real (verified): `WorkerHub.MergeTask → TaskMergeService.MergeAsync`
+performs a real `git merge --no-ff`, aborts on conflict, and marks the worktree
+`Merged`. **Open Diff** opens a real in-app diff. **Merge All Subtasks**
+(planning) is real. So the gaps are narrow.
+
+## Scope decisions (autonomous)
+
+- **Tab location:** keep the **single "Session" tab** that the recent commit
+  `ac9bae9` deliberately consolidated. All new controls go in its existing
+  `MERGE & WORKTREE` block (`WorkConsole.axaml:196`). Do **not** re-introduce a
+  separate "Actions" tab.
+- **Approve target:** Approve merges into the UI-selected merge target
+  (`SelectedMergeTarget`); when blank, the worker resolves to the repo's current
+  branch.
+- **On conflict:** task stays in `WaitingForReview` (no new status). The conflict
+  is surfaced inline. No automatic state change to a "blocked" status.
+- **Worktree removal on approve:** do **not** remove — merge marks the worktree
+  `Merged` and existing auto-cleanup handles disposal (matches the single-task
+  merge default `removeWorktree:false`).
+- **Applies to:** standalone leaf tasks with an active worktree. A
+  `WaitingForReview` task with **no** active worktree (e.g. ran in a sandbox, or
+  an improvement parent whose children own the worktrees) is just marked `Done`
+  — current behavior preserved. Planning parents keep "Merge All Subtasks".
+
+## Acceptance (restated)
+
+1. Approve a clean-merging task → worktree merged into target, worktree `Merged`,
+   task `Done`.
+2. Approve a conflicting task → task **not** `Done`, conflict surfaced.
+3. Opening a Done/WaitingForReview task shows clean/conflict status **without
+   mutating** the tree (use `git merge-tree`, not a real merge).
+
+## Architecture
+
+Three layers, each single-purpose; the only new cross-dependency is
+`TaskMergeService → ITaskStateService` (one-way; verify no DI cycle).
+
+### 1. GitService — non-destructive conflict probe (`ClaudeDo.Data`)
+
+New method:
+
+```csharp
+public sealed record MergePreview(bool Supported, bool Clean, IReadOnlyList<string> ConflictFiles);
+
+public async Task<MergePreview> PreviewMergeAsync(
+    string repoDir, string targetBranch, string sourceBranch, CancellationToken ct = default)
+```
+
+- Runs `git merge-tree --write-tree --name-only <target> <source>` from `repoDir`.
+  `merge-tree` computes the merge base itself and writes only loose objects — it
+  does **not** touch the working tree, index, or refs.
+- Exit code `0` → `Clean = true`, no conflict files.
+- Exit code `1` → `Clean = false`; conflicted paths are the lines after the
+  first (tree-OID) line, up to the first blank line.
+- Any other outcome (e.g. git too old → "unknown option") → `Supported = false`
+  (UI shows "mergeability unknown").
+
+New helper for the "· N files" count (clean case):
+`git diff --name-only <target>...<source>` (three-dot = changes on source since
+the merge base); count non-empty lines. May reuse/extend existing diff helpers.
+
+### 2. TaskMergeService — preview + approve orchestration (`ClaudeDo.Worker`)
+
+Inject `ITaskStateService` (verify `PlanningChainCoordinator` has no back-edge to
+`TaskMergeService`; if a cycle exists, fall back to orchestrating in the hub).
+
+```csharp
+public sealed record MergePreviewResult(string Status, IReadOnlyList<string> ConflictFiles, int ChangedFileCount);
+// Status: "clean" | "conflict" | "unavailable"
+public Task<MergePreviewResult> PreviewAsync(string taskId, string targetBranch, CancellationToken ct);
+
+public Task<MergeResult> ApproveAndMergeAsync(string taskId, string targetBranch, CancellationToken ct);
+```
+
+**PreviewAsync:** load context. If no active worktree → `"unavailable"`. Resolve
+`targetBranch` (blank → current branch). Call `GitService.PreviewMergeAsync`; map
+`Supported=false` → `"unavailable"`, else clean/conflict (+ ChangedFileCount on
+clean).
+
+**ApproveAndMergeAsync:** load context; require `task.Status == WaitingForReview`
+(else `Blocked`). Resolve target (blank → current branch).
+- **No active worktree** → `_state.ApproveReviewAsync(taskId)` → return
+  `MergeResult(StatusMerged, [], null)` ("approved, nothing to merge").
+- **Active worktree** → `MergeAsync(taskId, target, removeWorktree:false,
+  "Merge {branch}", ct)`. On `StatusMerged` → `_state.ApproveReviewAsync(taskId)`
+  then return the merged result. On `StatusConflict`/`StatusBlocked` → return as-is;
+  **do not** flip status (task stays `WaitingForReview`).
+
+`TaskStateService.ApproveReviewAsync` is unchanged (still the sole Status writer;
+still runs `OnChildTerminalAsync`).
+
+### 3. WorkerHub — signatures (`ClaudeDo.Worker`)
+
+```csharp
+public record MergePreviewDto(string Status, IReadOnlyList<string> ConflictFiles, int ChangedFileCount);
+
+public Task<MergePreviewDto> PreviewMerge(string taskId, string targetBranch);   // new
+public Task<MergeResultDto>  ApproveReview(string taskId, string targetBranch);  // CHANGED: was void(taskId)
+```
+
+`ApproveReview` returns the orchestration result so the UI can react to conflicts.
+`MergeTask` / `GetMergeTargets` unchanged.
+
+### 4. UI (`ClaudeDo.Ui`)
+
+`IWorkerClient` (+ `WorkerClient` + **both test-project fakes** — see memory:
+changing `IWorkerClient` breaks hand-rolled fakes):
+- Change `Task ApproveReviewAsync(string)` → `Task<MergeResultDto?> ApproveReviewAsync(string taskId, string targetBranch)`.
+- Add `Task<MergePreviewDto?> PreviewMergeAsync(string taskId, string targetBranch)`.
+- Add `Task<MergeResultDto> MergeTaskAsync(...)` to the **interface** (already on
+  the concrete client) so the single-task Merge button can use `_worker`.
+
+`DetailsIslandViewModel`:
+- **Load merge targets whenever a worktree exists.** In `BindAsync`, when
+  `entity.Worktree != null` and the task is not a planning parent, call
+  `GetMergeTargetsAsync(taskId)` and set `SelectedMergeTarget = DefaultBranch`
+  (fixes the standalone-task gap where targets were never loaded).
+- **Mergeability indicator** properties: `MergePreviewText` (string),
+  `MergeIsClean` / `MergeIsConflict` (bool, for color). Compute via
+  `PreviewMergeAsync` when the merge section is shown for an **Active** worktree;
+  recompute on `SelectedMergeTarget` change. If worktree state is
+  `Merged/Discarded/Kept`, show that label instead of probing. Text examples:
+  "Merges cleanly · 7 files" / "Conflicts in a.cs, b.cs" / "Mergeability unknown".
+- **Approve** (`ApproveReviewAsync`): pass `SelectedMergeTarget ?? ""`; inspect
+  result — on `"conflict"` set the conflict indicator + a short notice
+  ("Approve blocked — resolve conflicts first"); success path relies on the
+  existing `TaskUpdated` broadcast to refresh.
+- **Single-task Merge** (`MergeCommand`): `MergeTaskAsync(taskId,
+  SelectedMergeTarget ?? "", removeWorktree:false, "Merge task")`; on `"conflict"`
+  show the conflict indicator. Shown for non-planning tasks with an active
+  worktree (planning parents keep "Merge All Subtasks").
+
+`WorkConsole.axaml` (Session tab, `MERGE & WORKTREE` block):
+- Add a status line above the button row bound to `MergePreviewText`, colored
+  green (`MossBrush`) when `MergeIsClean`, red (`BloodBrush`) when
+  `MergeIsConflict`, muted otherwise. Use existing tokens/classes only.
+- Add a **Merge** button (`MergeCommand`) beside **Open Diff** for the
+  single-task path.
+
+## Testing (git-backed, no real Claude)
+
+In `ClaudeDo.Worker.Tests` (real temp git repos + real SQLite), and/or
+`ClaudeDo.Data.Tests` for the pure git probe:
+- `GitService.PreviewMergeAsync`: clean branches → `Clean=true`; a real
+  edit-conflict on the same lines → `Clean=false` with the expected file in
+  `ConflictFiles`.
+- `ApproveAndMergeAsync`: clean worktree → returns `merged`, task is `Done`,
+  worktree state `Merged`. Conflicting worktree → returns `conflict`, task still
+  `WaitingForReview`, worktree still `Active`, target branch unmodified
+  (HEAD unchanged, no `MERGE_HEAD`).
+- No-worktree `WaitingForReview` task → returns `merged`, task `Done`.
+
+## Out of scope
+
+External difftools, new task statuses, auto-removing worktrees on approve,
+re-splitting the console into separate tabs, conflict resolution UI (the existing
+`ContinueMerge`/`AbortMerge` paths remain as-is for mid-merge cases).

+# ClaudeDo distribution website — design
+
+**Date:** 2026-06-04
+**Status:** Approved (design), ready for implementation planning
+**Repo:** new standalone repo `claudedo-web` (not part of the ClaudeDo app solution)
+**Domain:** `claudedo.kuns.dev` (Coolify on the user's VPS)
+
+## Purpose
+
+Give friends a public place to download ClaudeDo and learn what it does, without
+sending them to the Gitea repo — so the source repo can be made more private. The
+site also fronts the app's self-updater so the Gitea URL is never exposed in the
+app or on the page.
+
+## Goals / non-goals
+
+**Goals**
+- Public, no-auth landing page at `claudedo.kuns.dev` that matches the app's visual identity.
+- A primary download (installer `.exe`) plus the portable `.zip` and checksums.
+- A release proxy that (a) feeds the page the current version and (b) serves the
+  app's self-updater the same JSON shape Gitea returns, with download URLs rewritten
+  to route through `claudedo.kuns.dev` — hiding Gitea entirely.
+
+**Non-goals**
+- No docs site / getting-started page (the app ships an installer that handles setup).
+- No changelog page (release notes already live on Gitea releases).
+- No auth, accounts, analytics, or CMS.
+- No CI/PR tooling for this repo beyond what Coolify needs to deploy.
+
+## Access & distribution decisions
+
+- **Access:** fully public. No password/login. Relies on the unadvertised URL.
+- **Download source:** build-time fetch of the latest Gitea release for the displayed
+  version; actual download links route through the proxy and resolve the latest asset
+  at request time (so a stale page still downloads the current build).
+- **Self-updater proxy:** in scope for v1 (not deferred).
+
+## Tech stack
+
+- **Nuxt 3** (Vue 3) — single framework, single repo, single Coolify deploy.
+- **Nitro** server routes for the release proxy + asset streaming.
+- **No DB, no auth, no secrets** (the `releases/ClaudeDo` repo is public).
+- Fonts: **Inter Tight** (display/body) + **JetBrains Mono** (mono), self-hosted or via
+  Google Fonts. Design tokens ported from `docs/UI Rewrite/design_handoff_claudedo/Tokens.axaml`
+  and `styles.css` (moss/sage/peat palette, dark-first, 14px island radius, grain texture).
+
+## Concept: "the page IS the app"
+
+The landing page is a faithful, in-browser rendering of the ClaudeDo desktop — the
+window chrome + the three islands — rather than a conventional marketing page. This
+is the chosen direction (over a cinematic single-window scroll and a worklog feed).
+
+### Layout — three islands on the app "desktop"
+
+Desktop background = the app's layered moss gradients + 3px grain overlay. A centered
+app `window` (titlebar + body) holds a 3-column island grid:
+
+1. **Lists island (left)** — repurposed as page nav.
+   - Header "Lists" + a decorative search box (`Ctrl K` kbd chip).
+   - "Pages" group: Overview · Features (6) · How it works · Screenshots (3) · Download,
+     each with a colored swatch dot; active item gets the accent left-bar.
+   - Footer styled like the app's user footer: avatar, "For friends", `claudedo.kuns.dev`.
+
+2. **Tasks island (middle)** — features rendered as **task cards**.
+   - Header: date eyebrow, big title (the hero line "Queue the work. Claude does it."),
+     a `running · review` badge, eye/gear icon buttons, and a subtitle.
+   - A decorative "Add a task…" row.
+   - Six **feature cards** (circle check — done cards filled; title; a status chip
+     `done`/`running`/`waiting for review`; a star). The features:
+     1. Isolated worktrees
+     2. The task queue
+     3. Review & merge
+     4. Live session log
+     5. Per-list & per-task config
+     6. Self-updating
+   - A "Ready" group with the final **"↓ Download ClaudeDo"** card.
+
+3. **Detail island (right)** — faithful to the reworked Task-Detail island.
+   - **Source of truth for the detail visuals:** `docs/superpowers/specs/2026-06-04-task-detail-redesign-design.md`
+     (the app's in-progress rework). The website's detail pane must track that design.
+   - Three-zone stack:
+     - **Task header** — mono id (`#F01…`), title, trash/gear action icons.
+     - **DETAILS bar** — `DETAILS` eyebrow + `Edit` / copy / `⋯`, then a **markdown body**
+       (headings, paragraphs, inline `code`, ordered/unordered lists) describing the feature.
+     - **WorkConsole** docked at the bottom — traffic-light dots, `· N turns · +x −y`,
+       tabs **Output / Actions / Session**, and a `Created …` footer.
+   - Per-feature mapping:
+     - Feature panels: markdown writeup in DETAILS + a short relevant **Output** log.
+     - "Review & merge": opens on the **Actions** tab with `Merge target` + `Open Diff` /
+       `Approve & merge`.
+     - **Download**: DETAILS shows requirements (`.NET 8 Desktop Runtime`, `Claude CLI`,
+       `Git`); the **Actions** tab holds the install controls, with `Merge target`
+       repurposed as a **Build** selector and buttons `↓ Download installer` /
+       `Portable .zip` / `checksums.txt`.
+
+4. **Statusbar (bottom)** — `● Online · claudedo.kuns.dev · private build`.
+
+### Interaction
+
+- Clicking a task card selects it (accent bar + card highlight) and swaps the active
+  detail panel; the WorkConsole tabs are clickable within a panel.
+- **All panels are server-rendered and present in the DOM**, toggled by class — the
+  page is fully readable and downloadable **without JavaScript** (progressive
+  enhancement). Vue handles the selection state on the client.
+
+### Responsive
+
+- ≤ ~1100px: drop the Detail island; show Lists + Tasks.
+- ≤ ~780px: single column — the Tasks list; tapping a feature pushes to a full-screen
+  Detail view (mirrors the app's narrow-window behavior) with a back affordance.
+
+## Server: release proxy (Nitro)
+
+The app's `ReleaseClient` (`src/ClaudeDo.Releases/ReleaseClient.cs`) calls
+`{apiBase}/releases/latest` and reads `tag_name`, `name`, and
+`assets[].browser_download_url`; `DownloadAsync` GETs an asset URL directly.
+
+- **`GET /api/releases/latest`** — fetches `https://git.kuns.dev/api/v1/repos/releases/ClaudeDo/releases/latest`,
+  returns the **same JSON shape**, but every `assets[].browser_download_url` is rewritten
+  from the Gitea URL to `https://claudedo.kuns.dev/api/download/<encoded-asset-path>`.
+  Cached briefly (e.g. 5 min) server-side.
+- **`GET /api/download/[...path]`** — reconstructs the Gitea asset URL from the path and
+  **streams** the binary back (no redirect to Gitea, so the URL stays hidden). Sets
+  appropriate `Content-Type`/`Content-Disposition`.
+- **`server/utils/gitea.ts`** — shared base URL (`GITEA_API`, `REPO` from env), fetch
+  helper, and the URL-rewrite/asset-path round-trip.
+- The page's download buttons point at the same `/api/download/...` routes (with a
+  stable "latest installer" path), so links never go stale between deploys.
+
+### App-side coordinating change (separate, in the ClaudeDo repo)
+
+Point `ReleaseClient`'s `apiBase` at `https://claudedo.kuns.dev/api` instead of the
+Gitea default (one-line DI change where `ReleaseClient`/`UpdateCheckService` are
+constructed). Tracked as a follow-up; not part of the `claudedo-web` repo. The proxy
+path (`/api/releases/latest`) is chosen to match the existing
+`{apiBase}/releases/latest` call so the parser is untouched.
+
+## Content / assets
+
+- **Screenshots (provided):** main 3-column view (hero), diff review modal, worktrees
+  panel. Stored in `public/screenshots/`. Placeholders sized for them until dropped in.
+- Copy: hero "Queue the work. Claude does it."; six feature writeups as above (final
+  wording during implementation).
+
+## Error handling
+
+- **Build-time release fetch fails:** render the page with a last-known/placeholder
+  version label; download buttons still work because they resolve via the runtime
+  proxy route.
+- **Proxy `/api/releases/latest` upstream failure:** return a 502/`null`-equivalent the
+  way Gitea would on miss; the app's `UpdateCheckService` already treats null/exception
+  as `CheckFailed` and degrades gracefully.
+- **`/api/download` upstream failure:** surface a 502; the button shows an error state.
+- No retries beyond a single upstream attempt for v1 (low traffic, friends-only).
+
+## Testing
+
+- **Vitest** unit tests for `server/utils/gitea.ts`: URL rewrite (Gitea → proxy) and the
+  asset-path round-trip (proxy path → Gitea URL), and release-JSON shape preservation.
+- A light component smoke test that the page renders the islands and the download
+  controls without JS errors.
+- No real-network/Gitea calls in tests — mock the upstream fetch.
+
+## Deployment (Coolify)
+
+- **Dockerfile**: `node:20-alpine` build → `nuxt build` → run `.output/server/index.mjs`.
+- Coolify app bound to `claudedo.kuns.dev` with TLS via its reverse proxy.
+- Env: `GITEA_API` (default `https://git.kuns.dev/api/v1`), `REPO` (`releases/ClaudeDo`),
+  `PUBLIC_BASE_URL` (`https://claudedo.kuns.dev`) for URL rewriting.
+- Deploy on push to `main`; re-deploy (or a periodic rebuild) refreshes the displayed
+  version. No PR/CI tooling beyond Coolify's build.
+
+## Open risk
+
+- The reworked Detail island in the app is still in flux. The website's detail pane
+  must be kept in sync with `2026-06-04-task-detail-redesign-design.md`; expect a
+  visual-polish pass once that rework lands.

+# Refine Task — Design
+
+**Date:** 2026-06-04
+**Status:** Approved (pending spec review)
+
+## Goal
+
+Add a one-click **Refine Task** action to a task card. Clicking it spawns a
+headless Claude session that reads the task (and the repo), rewrites the task's
+description to be clearer and runnable autonomously, and — where it helps —
+breaks the work into subtasks. The user then reviews/hand-edits the result and
+queues the task manually.
+
+This is **not** an interactive terminal session. It is a fire-and-forget
+headless run, structurally similar to the existing daily-prep ("Prime Claude")
+flow (`PrimeRunner`), not the interactive planning flow.
+
+## Non-goals / scope
+
+- No new task status. The task stays `Idle` throughout; refine only mutates the
+  task's `Title`/`Description` and its subtasks.
+- No worktree, no interactive terminal, no auto-queue.
+- No per-task refine config (model, turns) — uses the worker's defaults.
+- Refine does not edit repository files; repo access is read-only.
+
+## User flow
+
+1. User clicks the refine icon on an `Idle` task's card.
+2. UI calls `WorkerHub.RefineTask(taskId)` → `RefineRunner`.
+3. `RefineRunner` spawns `claude -p` headless in the list's working directory,
+   seeded with a fixed refine prompt + the task's title/description/current
+   subtasks + the task id.
+4. Claude reads the repo (read-only), then calls:
+   - `mcp__claudedo__update_task` to improve title/description, and
+   - `mcp__claudedo__add_subtask` to add steps where useful.
+   Each MCP call broadcasts `TaskUpdated`, so the description and Steps card
+   update live in the UI.
+5. Run finishes; the card's refine button returns to its idle state. User
+   reviews, optionally hand-edits the description/steps, then queues manually.
+
+## Architecture
+
+### Worker — `RefineRunner`
+
+- New `Worker/Refine/RefineRunner.cs` implementing `IRefineRunner`
+  (`Worker/Refine/Interfaces/IRefineRunner.cs`). Modeled on `PrimeRunner`.
+- **Concurrency / single-flight:** an in-flight `HashSet<string>` of task ids
+  guarded by a lock (or `SemaphoreSlim`), so the *same* task cannot refine
+  twice concurrently, but different tasks may refine in parallel. A second
+  click on an already-refining task is a no-op.
+- **Guards:** only runs when `task.Status == Idle`. Resolves the list's working
+  directory. If the list has **no valid working dir**, fall back to a sandbox
+  directory and run text-only (drop `Read`/`Grep`/`Glob` from the allowlist).
+- **CLI invocation** (relies on the globally-registered `claudedo` MCP, like
+  daily-prep — no `--mcp-config`):
+  ```
+  claude -p --output-format stream-json --verbose
+         --permission-mode acceptEdits
+         --max-turns <N>
+         --allowedTools mcp__claudedo__get_task,mcp__claudedo__update_task,mcp__claudedo__add_subtask,Read,Grep,Glob
+  ```
+  `Edit`/`Write`/`Bash` are deliberately **not** whitelisted, so the run is
+  read-only on the repo even under `acceptEdits`. (Chosen over `plan` mode to
+  avoid the headless "exit plan mode to act" friction; the allowlist is the
+  real read-only gate.)
+- **Logging:** stream stdout to a per-run log at
+  `logs/refine-<taskId[:8]>.log`, truncated at the start of each run.
+
+### Prompt — `PromptKind.Refine`
+
+- Add `Refine` to the `PromptKind` enum in `PromptFiles.cs`, file
+  `prompts/refine.md`, with a bundled default.
+- Default prompt instructs: refine one ClaudeDo task so it is ready to run
+  autonomously; ground the description in the actual code (read-only); keep
+  scope tight (no scope creep into adjacent work); add steps as subtasks only
+  when they genuinely help; use only `get_task`, `update_task`, `add_subtask`
+  and the read-only tools; never edit files.
+- Rendered via `PromptFiles.Render` with `{taskId}`, `{title}`,
+  `{description}`, and the current subtask list seeded into the prompt so the
+  agent knows which steps already exist.
+
+### MCP tool — `add_subtask`
+
+- New `[McpServerTool]` on `ExternalMcpService` (part of the global `claudedo`
+  MCP), signature `add_subtask(taskId, title, orderNum?)`.
+- Creates a `SubtaskEntity` via `SubtaskRepository`; `orderNum` defaults to
+  append-at-end (max existing + 1). Refuses if the task is `Running`.
+  Broadcasts `TaskUpdated`.
+- **Append semantics, not replace:** the current subtasks are already in the
+  prompt, so the agent only adds missing steps; re-running refine will not
+  silently wipe steps the user hand-edited.
+- `update_task` already exists (title/description/commitType) and is reused
+  unchanged.
+
+### UI — button, icon, feedback
+
+- **Icon:** add the supplied SVG as an `Icon.Refine` `StreamGeometry` in
+  `IslandStyles.axaml`, rendered as a **stroked `Path`** (`plan-icon` style,
+  fill none) — it is line art, so per the PathIcon-fills-geometry gotcha it
+  must be stroked, not filled.
+- **Button:** a new `icon-btn` in `TaskRowView.axaml` near the star button,
+  visible only when the task is `Idle`. Bound to a new `RefineTaskCommand` on
+  `TasksIslandViewModel`.
+- **Feedback:** new broadcaster events `RefineStarted(taskId)` /
+  `RefineFinished(taskId, ok, error?)` drive an `IsRefining` flag on
+  `TaskRowViewModel`; the button shows a busy/disabled state while running. The
+  description and Steps card update live via the existing `TaskUpdated` events
+  fired by the MCP calls.
+- Wire `RefineTask` through `IWorkerClient` / `WorkerClient`, the `WorkerHub`
+  method, and update the hand-rolled test fakes in both test projects.
+
+## Testing
+
+- `add_subtask`: creates the row, appends order correctly, refuses when
+  `Running`, broadcasts `TaskUpdated`.
+- Refine prompt builder and CLI-args builder produce the expected prompt/flags
+  (including the text-only fallback when no working dir).
+- `RefineRunner` guards: `Idle`-only, per-task single-flight no-op on a second
+  concurrent call.
+- **No test spawns the real `claude` CLI** (project rule). The end-to-end run
+  is a manual smoke step.
+
+## Open implementation calls (decided)
+
+- **Permission mode:** `acceptEdits` + restricted allowlist for read-only
+  (rather than `plan` mode).
+- **`add_subtask`:** append-only (rather than replace-all).

+# Task Detail Island Redesign — Design
+
+**Date:** 2026-06-04
+**Status:** Approved (design), pending implementation
+**Author:** brainstormed with user via visual companion
+
+## Problem
+
+The Detail island (`DetailsIslandView`, 413 lines) grew into one long scrolling
+column as features piled on. The user has to scroll constantly. Specific pains
+(confirmed by the user):
+
+- **Everything is always stacked** — Steps, Description, Terminal, and several
+  conditional sections share one scroll column with no way to hide/fold.
+- **Duplicated info** — `model` shows in the gear flyout *and* the agent strip;
+  the branch line shows in the agent strip *and* as the terminal label.
+- **Agent strip is a heavy 5-row block** pinned near the bottom even when idle.
+- **Steps + Description take a lot of room** before the action controls.
+
+The terminal staying prominent is *fine* — not a pain point.
+
+## Solution overview
+
+Replace the linear body with a **fixed-region layout** built from **3 new
+self-contained components**, plus a roadblock band. Top region (header + details
+card) stays put; the work console is pinned to the lower third.
+
+```
+┌─────────────────────────────────────┐
+│ TaskHeaderBar      (separated title) │   #T42 · title · 🗑/💀 · ⚙
+├─────────────────────────────────────┤
+│ DescriptionStepsCard                 │   card; text ⇄ steps toggle icon
+│   (Preview = what Claude gets)       │   copy · preview/edit
+├─────────────────────────────────────┤
+│ Roadblock band (only when failed)    │   ⚠ message · Continue · Reset&Retry
+├─────────────────────────────────────┤
+│ WorkConsole       (pinned, terminal) │   ●●● · model·turns·diff
+│   tabs: Output | Actions | Session   │
+└─────────────────────────────────────┘
+```
+
+## The 3 components
+
+Each is a standalone `UserControl` + dedicated `ViewModel` with **design-time
+sample data** so it renders fully in the Avalonia previewer in isolation. Built
+in separate worktrees; **none touch `DetailsIslandView.axaml` or
+`DetailsIslandViewModel.cs`** (that is the wiring session). All visuals use
+**only** the existing design tokens (`Design/Tokens.axaml`) and style classes
+(`Design/IslandStyles.axaml`) — no hardcoded colors/sizes.
+
+New folder: `src/ClaudeDo.Ui/Views/Islands/Detail/`
+New VMs: `src/ClaudeDo.Ui/ViewModels/Islands/Detail/`
+
+### 1. TaskHeaderBar
+
+- **Layout:** one row — `#T42` id badge (mono `meta`, copyable) · editable title
+  `TextBox` (transparent, `FontSizeTaskTitle`, wraps) · **trash/skull button** ·
+  ⚙ gear button with the agent-settings flyout.
+- **Trash → Skull:** when **not** running show `Icon.Trash` (delete task,
+  `BloodBrush`); when **running** show a **skull** glyph (kill session). One
+  button, swaps icon + command on running state. Skull is a *new* filled
+  geometry to add to `IslandStyles.axaml` resources (`Icon.Skull`).
+- **No done circle. No star** (the star lives on the task card/row already).
+- **Gear flyout:** keep the existing agent-settings content verbatim — Model
+  combo + `InheritedBadge` + reset; Max Turns `NumericUpDown` + badge + reset;
+  System Prompt `TextBox` + "prepended" hint; Agent File combo + badge + reset.
+  Disabled while running (`IsAgentSectionEnabled`).
+- **Existing bindings reused:** `TaskIdBadge`, `EditableTitle`, `DeleteTaskCommand`,
+  `StopCommand`, `IsRunning`, `IsAgentSectionEnabled`, all the agent-settings
+  members (`TaskModelOptions`/`TaskModelSelection`/`ModelBadge`/
+  `ResetTaskModelCommand`/`TaskMaxTurns`/`TurnsBadge`/`ResetTaskTurnsCommand`/
+  `TaskSystemPrompt`/`EffectiveSystemPromptHint`/`TaskAgentOptions`/
+  `TaskSelectedAgent`/`AgentBadge`/`ResetTaskAgentCommand`).
+
+### 2. DescriptionStepsCard
+
+A `Border.island`-style card. The single explicitly-requested "separate
+component." Top-right **toggle icon** switches the card between **Description**
+and **Steps** views; the icon shows the *other* mode (in Description view → steps
+icon `Icon.MoreHorizontal`/list glyph; in Steps view → text glyph).
+
+- **Header row:** small `section-label` ("DETAILS" / "STEPS") · spacer · **Copy**
+  icon button (`Icon.Copy`) · **Preview/Edit** toggle button (Description view
+  only) · **toggle icon** (top-right).
+- **Description view:**
+  - *Preview mode* = renders **what Claude gets** via `MarkdownView`: the
+    canonical composed text (Title + Description + open steps — see below).
+  - *Edit mode* = raw description `TextBox` (mono, `Surface2Brush`, multiline).
+- **Steps view:** add-step input (Enter to add) + list of step rows (check
+  circle `Ellipse.task-check` + inline-editable title, `subtask-row` style).
+- **Copy** copies the **formatted** version (Title + Description + open steps),
+  nothing else, to the clipboard.
+- **Existing bindings reused (when wired):** `EditableDescription`,
+  `IsEditingDescription`/`ToggleEditDescriptionCommand`, `Subtasks`,
+  `NewSubtaskTitle`/`AddSubtaskCommand`, `ToggleSubtaskDoneCommand`,
+  `CommitSubtaskEditCommand`.
+- **New members (defined on the component VM now, lifted into
+  `DetailsIslandViewModel` at wiring):** `IsStepsView` + `ToggleCardViewCommand`;
+  `ComposedPreview` (string, the canonical format); `CopyFormattedCommand`.
+
+### 3. WorkConsole
+
+Terminal-styled card (`Border.terminal`) pinned to the lower third.
+
+- **Title bar:** three cosmetic traffic-light dots (`Ellipse.dot-red`,
+  `dot-yellow`, `dot-green`) on the left; centered/!right small **info header**:
+  `model · {turns} turns · +adds −dels` (mono `meta`; `diff-add`/`diff-del`
+  classes for the numbers). **No branch line.** LIVE/DONE/FAILED chip
+  (`live-chip`) on the right.
+- **Tab strip:** `Output` | `Actions` | `Session`.
+  - **Output** — the live log. Reuse `SessionTerminalView` (`Entries`, `Label`,
+    `IsRunning`, `IsDone`, `IsFailed`) for the body, *or* the same
+    timestamp+`SelectableTextBlock` row template.
+  - **Actions** — worktree management: merge-target `ComboBox`, **Open Diff**,
+    **Worktree**, **Merge** (+ planning **Merge All Subtasks** when planning
+    parent). Bindings: `MergeTargetBranches`/`SelectedMergeTarget`,
+    `OpenDiffCommand`, `OpenWorktreeCommand`, `MergeAllCommand`/`CanMergeAll`/
+    `MergeAllDisabledReason`/`MergeAllError`, `ReviewCombinedDiffCommand`.
+  - **Session** — review + outcomes: feedback `TextBox` + Approve/Reject/Park/
+    Cancel (`ReviewFeedback`, `ApproveReviewCommand`, `RejectReviewCommand`,
+    `ParkReviewCommand`, `CancelReviewCommand`, shown when `IsWaitingForReview`)
+    and the child-outcomes list (`ChildOutcomes`, `HasChildOutcomes`).
+- **Roadblock band** (above the tabs, inside or just above the card): visible on
+  `IsFailed`/`IsCancelled`; shows a warning (`Icon.Warning`, `BloodBrush`) and
+  **Continue** (`ContinueCommand`, `ShowContinue`) + **Reset & Retry**
+  (`ResetAndRetryCommand`, `ShowResetAndRetry`).
+- **Info-header bindings:** `Model`, `Turns`, `DiffAdditions`, `DiffDeletions`,
+  `IsRunning`/`IsDone`/`IsFailed`.
+
+## Combined Description + Steps behavior
+
+Steps are part of the description. When the task runs, the **effective prompt =
+Title + Description + only the OPEN steps**. Resolved steps are dropped.
+
+**Canonical composed format** (shared by the Worker prompt, the card's Preview,
+and Copy):
+
+```
+<Title>
+
+<Description>
+
+## Sub-Tasks
+- [ ] <open step 1>
+- [ ] <open step 2>
+```
+
+- Omit the `## Sub-Tasks` section entirely when no open steps remain.
+- Omit the description paragraph when description is empty.
+
+**Worker change (wiring session, by Claude):** `TaskRunner.cs:104-113` currently
+appends *all* subtasks with `[x]`/`[ ]`. Change to append **only incomplete**
+subtasks as `- [ ]` lines (drop completed). Factor the format into a shared
+`TaskPromptComposer` in `ClaudeDo.Data` (referenced by both Worker and UI) so the
+card's Preview and the real prompt never diverge.
+
+## Color / token guidelines (mandatory)
+
+- Backgrounds: `IslandBackgroundBrush`, `Surface2Brush`, `Surface3Brush`,
+  `DeepBrush`, `VoidBrush` (terminal). Borders: `LineBrush`/`LineBrightBrush`,
+  `HairlineOverlayBrush`. Text: `TextBrush`/`TextDimBrush`/`TextMuteBrush`/
+  `TextFaintBrush`. Accent: `AccentBrush`/`AccentDimBrush`. Status: blood/peat/
+  moss/sage + the `*TintBrush` pairs.
+- Radii: `IslandCornerRadius` (14), `ButtonCornerRadius` (6), `InputCornerRadius`
+  (8). Spacing: `SpaceXs..Space2Xl`. Fonts: `SansFont`, `MonoFont`; sizes
+  `FontSizeMono`/`FontSizeBody`/`FontSizeTaskTitle`.
+- Reuse style classes: `island`, `island-header`, `chip`, `btn`/`btn accent`/
+  `primary`/`danger`, `icon-btn`, `flat`, `terminal`, `dot-red/yellow/green`,
+  `live-chip`, `task-check`, `subtask-row`, `section-label`, `field-label`,
+  `meta`, `diff-add`/`diff-del`, `diff-meter-*`.
+- **No inline hex, no magic numbers** where a token exists. `PathIcon` fills
+  geometry — line-art must be filled or stroked via `Path`.
+
+## Build / isolation strategy
+
+1. Three ClaudeDo tasks (list "Claude do", repo `C:\Private\ClaudeDo`), one per
+   component, run sequentially in their own worktrees.
+2. Each delivers: `Detail/<Name>.axaml` + `.axaml.cs` + `Detail/<Name>ViewModel.cs`
+   with design-time sample data; the `ClaudeDo.Ui` project **builds green**
+   (`dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj -c Release`).
+3. Components are visual-only against sample data. Real `DetailsIslandViewModel`
+   binding + the Worker steps→prompt change happen in the **wiring session**
+   (this Claude session, done while the build tasks run).
+
+## Wiring plan (this session)
+

+# Git Tab / Merge & Review Rework — Design
+
+Date: 2026-06-05
+Status: Approved
+
+## Goal
+
+Make handling merges and reviews as simple as possible in the Terminal component's
+Git tab, and rework the diff viewers and worktree modals along the way. The work is
+split into three layers built across separate sessions, with a shared foundation that
+is built and pushed first so the parallel sessions branch from frozen contracts.
+
+The user mostly trusts task output but wants the diff one click away for important
+work, and wants to land several independently-queued worktrees without per-task
+hopping or hand-resolving conflicts in an external editor.
+
+## Layers
+
+- **Layer A — Review/merge cockpit** (this session). Single-task review + merge UX in
+  the Git tab; consolidate the four diff renderers into one `DiffView`.
+- **Layer B — Multi-worktree merge cockpit** (parallel session). Batch-merge N
+  worktrees into one target, skip-and-continue, conflicts collected for resolution.
+- **Layer C — Inline conflict resolver** (parallel session). VSCode-style inline hunk
+  resolver plus the worker-side conflict plumbing it needs.
+
+They stack: A defines the single-task flow, B reuses it for many tasks, both funnel
+conflicts into C.
+
+## Shared foundation (built & pushed this session, before B/C branch)
+
+Everything B and C depend on lands first on `main`. B and C branch from that commit.
+
+### 1. One diff model + one `DiffView` control
+
+Today there are four diff renderers and two parallel diff models:
+
+- `DiffLinesView.axaml` (used by `DiffModalView`)
+- the inline diff `ItemsControl` in `WorktreeModalView.axaml`
+- `PlanningDiffView.axaml`
+- their backing models: `DiffFileViewModel`/`DiffLineViewModel` (+ `UnifiedDiffParser`)
+  vs `WorktreeNodeViewModel`/`WorktreeDiffLineViewModel`
+
+Collapse into a single canonical diff model + parser + a `DiffView` UserControl. All
+diff rendering across the app goes through `DiffView`.
+
+- Model: `DiffFileViewModel { Path, AddCount, DelCount, Lines }`,
+  `DiffLineViewModel { OldNo, NewNo, Kind (Add|Del|Ctx|File|Hunk), Text }`.
+- Parser: one static `UnifiedDiffParser.Parse(rawUnifiedDiff)` returning the model.
+- `DiffView` exposes a `Files` styled property (file list + selected-file lines), or a
+  simpler `Lines` property for single-file use — Layer A decides the exact surface
+  while building it, but the type names above are frozen so B and C can bind to them.
+
+### 2. Frozen worker conflict contract
+
+Added to `IWorkerClient` (and `WorkerClient` with stub bodies that throw
+`NotSupportedException`) plus new DTOs, so A and B compile against the interface while
+C provides the real worker-side implementation.
+
+```csharp
+// IWorkerClient additions (signatures frozen this session)
+Task<MergeResultDto>            StartConflictMergeAsync(string taskId, string targetBranch);
+Task<MergeConflictsDto>         GetMergeConflictsAsync(string taskId);
+Task                            WriteConflictResolutionAsync(string taskId, string path, string resolvedContent);
+Task<MergeResultDto>            ContinueMergeAsync(string taskId);
+Task                            AbortMergeAsync(string taskId);
+```
+
+- `StartConflictMergeAsync` performs the merge with `leaveConflictsInTree: true` (the
+  worker already supports this flag — used today by the planning orchestrator) and
+  returns `MergeResultDto` with `Status="conflict"` and the conflict file list, leaving
+  `.git/MERGE_HEAD` in place in the list's `WorkingDir`.
+- `GetMergeConflictsAsync` returns each conflicted file with ours/theirs/base content,
+  read via `git show :2:<path>` (ours), `:3:<path>` (theirs), `:1:<path>` (base).
+- `WriteConflictResolutionAsync` writes resolved content to the file in `WorkingDir`
+  and `git add`s it.
+- `ContinueMergeAsync` wraps the existing `TaskMergeService.ContinueMergeAsync`
+  (`git add -A` → re-check `git diff --name-only --diff-filter=U` → `git commit`).
+- `AbortMergeAsync` wraps the existing `TaskMergeService.AbortMergeAsync`
+  (`git merge --abort`).
+
+New DTOs (defined in the worker hub DTO file, mirrored client-side):
+
+```csharp
+public record MergeConflictsDto(string TaskId, IReadOnlyList<ConflictFileDto> Files);
+public record ConflictFileDto(string Path, IReadOnlyList<ConflictHunkDto> Hunks);
+public record ConflictHunkDto(string Ours, string Theirs, string? Base);
+```
+
+Existing DTOs reused unchanged: `MergeResultDto(Status, ConflictFiles, ErrorMessage)`,
+`MergePreviewDto`, `MergeTargetsDto`.
+
+### 3. Conflict data model (UI)
+
+`ConflictFile { Path, Hunks[] }`, `ConflictHunk { Ours, Theirs, Base, Resolution }`.
+Shaped so a future 3-way merge pane needs no model change (Layer C is the inline
+resolver now; the model leaves room for 3-way later).
+
+### 4. Integration seams (delegates, wired by the integrator at merge)
+
+A's and B's cockpits hold a `RequestConflictResolution(string taskId)` callback (an
+`Action<string>` or `Func<string, Task>`). They never reference Layer C's resolver
+types. The integrator connects these callbacks to C's `ConflictResolverViewModel`
+factory when merging the three branches together.
+
+## Parallel boundaries (verified disjoint)
+
+| Area | A (this session) | B (parallel) | C (parallel) |
+|---|---|---|---|
+| `DiffView` + diff model/parser | builds | reuses | reuses |
+| `WorkConsole.axaml` / `DetailsIslandViewModel` | owns | — | — |
+| `DiffModalView` + `PlanningDiffView` | migrates to `DiffView` | — | — |
+| `WorktreesOverviewModalView/VM` + `WorktreeModalView` | — | owns | — |
+| `WorkerHub` / `TaskMergeService` / `GitService` | — | — | owns |
+| New `ConflictResolverView/VM` + conflict UI model | — | — | owns |
+| `IWorkerClient` / `WorkerClient` | adds frozen stubs + DTOs | reuses `MergeTaskAsync` | fills stub bodies |
+| Test fakes (`IWorkerClient`) in both test projects | adds new no-op methods | — | makes them functional if needed |
+
+The only file C and A both touch is `WorkerClient.cs` (C replaces the stub bodies A
+wrote). Contained; reconciled at integration. Everything else is disjoint.
+
+## Layer A — review/merge cockpit (this session)
+
+- The Git tab becomes the single Approve + merge surface. `Approve` and the merge
+  target / preview / diff flow together as one block (no separate REVIEW vs
+  MERGE & WORKTREE sections).
+- `Continue` (reject → requeue with feedback) and `Reset` (reject → idle) **stay** in
+  the Output tab footer — unchanged.
+- The diff is shown via the unified `DiffView` opened as a modal from the cockpit. No
+  inline diff recap in the tab (the island is too small).
+- On a single-task **Approve that conflicts**: instead of today's auto-abort, call
+  `StartConflictMergeAsync` and fire `RequestConflictResolution(taskId)`. This leaves
+  the main checkout mid-merge until the user resolves or aborts (behavior change,
+  intended). The callback is inert until Layer C is merged; the integrator wires it.
+- Migrate `DiffModalView` and `PlanningDiffView` onto the new `DiffView`.
+
+### Behavior change accepted
+
+Today `MergeTask`/`ApproveReview` use `leaveConflictsInTree: false` (auto-abort on
+conflict). Under this design, an Approve that conflicts leaves the merge in progress
+and opens the resolver. The mid-merge guard (`IsMidMergeAsync`) still prevents a second
+concurrent merge.
+
+## Layer B — multi-worktree merge cockpit (parallel)
+
+- Rework `WorktreesOverviewModalView`/`WorktreesOverviewModalViewModel` into a
+  batch-merge cockpit: list mergeable worktrees, select N, choose one target branch
+  (single target — 99% of the time everything goes to the same branch), "Merge all".
+- **Skip-and-continue**: client-side loop calling the existing
+  `MergeTaskAsync(taskId, target, removeWorktree, msg)` per selected task. Clean merges
+  apply; conflicting ones are collected (existing `MergeTaskAsync` auto-aborts on
+  conflict, leaving the tree clean) into a "needs resolution" list with live progress.
+- Each conflict row exposes a **Resolve** action → `RequestConflictResolution(taskId)`
+  (wired to Layer C at integration).
+- Per-task diff via the shared `DiffView`; migrate `WorktreeModalView`'s inline diff
+  onto it.
+- B touches no worker files — keeps it parallel-safe.
+
+## Layer C — inline conflict resolver (parallel)
+
+### Worker side
+
+Implement the five frozen contract methods:
+
+- Add hub methods `StartConflictMerge`, `GetMergeConflicts`, `WriteConflictResolution`,
+  `ContinueMerge`, `AbortMerge` in `WorkerHub`.
+- `StartConflictMerge` calls the existing `TaskMergeService.MergeAsync` overload with
+  `leaveConflictsInTree: true`.
+- `ContinueMerge` / `AbortMerge` wrap the existing `TaskMergeService.ContinueMergeAsync`
+  / `AbortMergeAsync` (currently service-level only, not hub-exposed).
+- `GetMergeConflicts` reads ours/theirs/base per conflicted file via
+  `git show :2:/:3:/:1:`; add the `GitService` helpers needed.
+- `WriteConflictResolution` writes the resolved content to `WorkingDir` and stages it.
+- Fill the `WorkerClient` stub bodies (real SignalR `InvokeAsync` calls).
+- Update the hand-rolled `IWorkerClient` fakes in both test projects.
+
+### UI
+
+- New `ConflictResolverView` + `ConflictResolverViewModel`. Per conflict hunk, show
+  ours vs theirs stacked, with buttons **Accept Current / Accept Incoming / Accept Both
+  / Edit manually** plus a free-text box for the merged result of that hunk.
+- When every file's hunks are resolved → `ContinueMergeAsync(taskId)` → `MergeResultDto`
+  (`merged` closes the resolver; `conflict` means not fully resolved, stay open).
+- `AbortMergeAsync(taskId)` cancels and aborts the merge.
+- Expose a factory (`Func<string, ConflictResolverViewModel>`) the integrator wires to
+  A's and B's `RequestConflictResolution` callbacks.
+
+## Build / test
+
+`.slnx` needs .NET 9; on .NET 8 build individual csproj with `-c Release` (a running
+Worker locks `Debug`). Run the relevant test projects. No tests that spawn the real
+`claude` CLI. Keep `en.json`/`de.json` localization keys in parity.
+
+## Out of scope
+
+- Full 3-way synchronized merge editor (model leaves room; not built now).
+- Per-task differing merge targets in the batch (single target only).
+- Any CI/PR tooling (direct push-to-main workflow).

+# Terminal-style review controls
+
+**Date:** 2026-06-05
+**Status:** Approved (design)
+
+## Problem
+
+Review feedback today is a multi-line `TextBox` plus four buttons (Approve / Reject /
+Park / Cancel) tucked into the WorkConsole **Session** tab
+(`WorkConsole.axaml:169-193`). It feels disconnected from the live terminal. Entering
+feedback should feel like typing into the terminal, with action buttons docked at the
+bottom — and merge/approve actions should live in an obvious, dedicated place.
+
+## Goal
+
+- Type review feedback directly in the **Output (terminal)** tab, prompt-style.
+- Bottom-docked action strip on the terminal: `[Retry]` `[Reset]`.
+- Move all git/merge/worktree actions (including **Approve**) into a new **Git** tab so
+  it is obvious where each action lives.
+
+## Tab structure
+
+Three tabs in WorkConsole: **Output** · **Git** · **Session**.
+
+| Tab | Contents |
+| --- | --- |
+| **Output** | Live `Log` (unchanged) + new review footer (below), footer gated on `IsWaitingForReview`. |
+| **Git** | The current "Merge & worktree" block — merge-target dropdown, mergeability indicator, **Approve**, Open Diff, Merge, Worktree, Review Combined Diff, Merge All Subtasks. Visibility gated on `ShowMergeSection` / `IsWaitingForReview` as today. |
+| **Session** | Child outcomes + empty-state only. |
+
+### ViewModel changes (`DetailsIslandViewModel`)
+
+- Add `public bool IsGitTab => SelectedTab == "git";`
+- Add `[NotifyPropertyChangedFor(nameof(IsGitTab))]` alongside the existing
+  `IsOutputTab` / `IsSessionTab` notifications on `SelectedTab` (`:139-144`).
+- `SelectTab` already accepts a string parameter — no change beyond the new `"git"`
+  value wired from XAML.
+- No command renames (avoids breaking hand-rolled test fakes).
+
+## Terminal footer (Output tab)
+
+A `Border` docked `Bottom` inside the Output tab body, visible only when
+`IsWaitingForReview`:
+
+- Background `Surface2Brush`, top border `LineBrush` (`BorderThickness="0,1,0,0"`).
+- A `❯` prompt-prefix `TextBlock` (mono, `TextMuteBrush`) + a borderless mono `TextBox`:
+  - Bound `Text="{Binding ReviewFeedback, Mode=TwoWay}"`.
+  - `AcceptsReturn="True"`, `TextWrapping="Wrap"`, transparent background, no border.
+  - Starts ~1 line tall; grows with content up to `MaxHeight≈160`, then scrolls.
+  - `PlaceholderText` e.g. "Feedback for the next run…".
+- Right-aligned button strip:
+  - `[Retry]` — `Classes="btn accent"` → `RejectReviewCommand`.
+  - `[Reset]` — `Classes="btn"` → `ParkReviewCommand`.
+
+`[Accept]` is **not** in the footer; approval happens on the Git tab via
+`ApproveReviewCommand`. The old `Cancel` review button is dropped from this UI; cancel
+remains reachable through the task's existing cancel control (`CancelReviewCommand`
+stays on the ViewModel, just not surfaced here).
+
+### Enter handling (`WorkConsole.axaml.cs`)
+
+- Handle `KeyDown` on the input `TextBox`:
+  - **Enter** without Shift → execute `RejectReviewCommand` (if it can execute) and set
+    `e.Handled = true`.
+  - **Shift+Enter** → fall through to default behavior (inserts newline).
+- `RejectReviewAsync` already returns early on whitespace-only feedback
+  (`DetailsIslandViewModel.cs:1464`), so pressing Enter with an empty prompt is a no-op
+  with no extra guard needed.
+
+## Command mapping
+
+| Button | Location | Command | Effect |
+| --- | --- | --- | --- |
+| `[Retry]` | Output footer | `RejectReviewCommand` | Reject-to-queue with feedback; resumes the session (Queued). |
+| `[Reset]` | Output footer | `ParkReviewCommand` | Park back to Idle. |
+| `[Approve]` | Git tab | `ApproveReviewCommand` | Merge `SelectedMergeTarget` → Done (conflict keeps it in review). |
+
+## Copy / empty state
+
+- Update the Session empty-state text (`WorkConsole.axaml:270`) — it currently says
+  "review and merge controls appear here once the run finishes", which is no longer
+  accurate. Reword to reflect that only outcomes live on Session.
+- Button labels remain literal strings (`Retry`, `Reset`, `Approve`), matching the
+  existing review buttons (no new localization keys).
+
+## Out of scope
+
+- No changes to worker-side review/merge logic or `IWorkerClient` signatures.
+- No merge-target selector duplicated into the terminal footer (Approve uses the Git
+  tab dropdown / default target).
+- No command renames on the ViewModel.
+
+## Testing / verification
+
+- Build `ClaudeDo.App` and `ClaudeDo.Worker` in `-c Release`.
+- Manual visual verification (must be flagged — cannot be auto-verified):
+  - Footer appears only in `WaitingForReview`, on the Output tab.
+  - Enter sends Retry; Shift+Enter inserts a newline; empty Enter does nothing.
+  - Git tab shows Approve + merge/worktree controls; Session shows only outcomes.

+# Unify the parent-task model (planning · improvement · normal)
+
+**Date:** 2026-06-09
+**Status:** Approved-pending-implementation
+
+## Problem
+
+ClaudeDo has three ways a task produces and waits on work, grown as separate
+mechanisms that represent the *same shape* — "a task runs, may emit children,
+and once it + its children are terminal it surfaces for review":
+
+| | children authored | scheduling | parent flow today | merge of children |
+|---|---|---|---|---|
+| **Normal** | none | — | `Running → WaitingForReview → Done` | own worktree on approve |
+| **Improvement** | autonomously *during* run (`suggest_improvement`) | parallel (no blockers) | `Running → WaitingForChildren → WaitingForReview → Done` | separate `MergeAllPlanning` |
+| **Planning** | interactively *before* run (planning session) | sequential chain (`BlockedByTaskId`) | `Idle →(Active→Finalized)→ Done` (skips review) | separate `MergeAllPlanning` |
+
+The incidental divergence we want to remove:
+
+1. **Two "parent is waiting on children" representations** — improvement uses
+   `Status=WaitingForChildren`; planning uses `PlanningPhase=Finalized` with the
+   parent's `Status` jumping `Idle → Done`, never passing through the waiting/review
+   states at all.
+2. **Two parent-advance methods** doing the same job —
+   `TaskRepository.TryCompleteParentAsync` (planning → `Done`, no review) vs
+   `TaskStateService.TryAdvanceImprovementParentAsync` (improvement → `WaitingForReview`).
+3. **A separate merge action** — `MergeAllPlanning` / `PlanningMergeOrchestrator`
+   merges children, decoupled from the parent's `approve`. Approving a parent and
+   merging its unit are two clicks.
+
+What is **genuinely unique and kept**: `PlanningPhase.Active` — the interactive,
+human-in-the-loop authoring gate where children are drafted and cannot run until
+finalize. Improvement has no equivalent. The two *authoring* entry points
+(`PlanningMcpService.CreateChildTask` vs `TaskRunMcpService.SuggestImprovement`)
+also stay distinct — they already share `CreateChildAsync`; unifying the authoring
+UX is explicitly out of scope.
+
+## Decisions (locked)
+
+- **All parents get review.** A planning parent now surfaces in `WaitingForReview`
+  after its children finish, instead of auto-completing to `Done`.
+- **Approve merges the whole unit — full UX consolidation.** Approve is the single
+  entry for reviewing *and* merging any task. For a parent with children it drives the
+  existing `PlanningMergeOrchestrator` (unit merge + parent→`Done` + conflict
+  continue/abort, all already implemented); the standalone "Merge All" button is
+  removed and the orchestrator's conflict dialog + combined-diff preview are reused
+  in-place. Childless tasks keep `ApproveAndMergeAsync`.
+- **Scope = state model + code paths.** Internal refactor; authoring UX and child
+  base-commit resolution are unchanged.
+
+## Target model
+
+**One parent-with-children lifecycle, used by every parent regardless of how its
+children were authored:**
+
+```
+                          ┌─ (no children) ──────────────┐
+Idle → Queued → Running ──┤                              ├→ WaitingForReview → Done
+                          └─ (has/spawns children) ─┐    │      (approve =
+                                                    │    │       merge unit)
+                                WaitingForChildren ─┘    │
+                                       │                 │
+                          (all children terminal) ───────┘
+```
+
+Planning parent (never runs as an agent — it runs an interactive session):
+
+```
+Idle (PlanningPhase None)
+  →[StartPlanning]      Idle (PlanningPhase Active)        ← authoring gate (KEPT)
+  →[FinalizePlanning]   WaitingForChildren (Finalized)     ← children chain runs
+  →[all children terminal]  WaitingForReview
+  →[approve]            merge unit → Done
+```
+
+Children (planning **and** improvement) keep going straight to `Done` with no
+individual review; they accumulate on their branches and merge as a unit when the
+parent is approved.
+
+### State machine after the change
+
+- `WaitingForChildren` is the **single** "parent waiting on children" state, used by
+  both planning and improvement parents.
+- `WaitingForReview` is reached by every parent before `Done`.
+- `PlanningPhase`: `None | Active | Finalized` — unchanged; `Active` remains the
+  authoring gate, `Finalized` marks "was a planning parent" and is set together with
+  `Status=WaitingForChildren`.
+
+## Code changes
+
+1. **Single parent-advance path.** Rename
+   `TaskStateService.TryAdvanceImprovementParentAsync` →
+   `TryAdvanceParentAsync`; it already only checks `Status==WaitingForChildren` +
+   "all children terminal" → `WaitingForReview` (with the failed/cancelled
+   annotation on `Result`). It becomes the only path for both systems.
+   - Handle **zero children**: a finalized planning parent with no children must go
+     straight to `WaitingForReview` (today `TryComplete`/`TryAdvance` both `return`
+     on `Count == 0`).
+
+2. **Delete `TaskRepository.TryCompleteParentAsync`** (`TaskRepository.cs:477`) and
+   its invocation in `TaskStateService.OnChildTerminalAsync`. Planning parents now
+   advance via `TryAdvanceParentAsync` to `WaitingForReview` instead of `Done`.
+   - Keep `_chain.OnChildFinishedAsync` (inter-child unblock — planning-only effect).
+
+3. **`FinalizePlanningAsync`** (`TaskStateService.cs:289`) sets the parent
+   `Status = WaitingForChildren` in the same update that sets
+   `PlanningPhase = Finalized`. This happens before `SetupChainAsync` enqueues
+   child[0], so the parent is in `WaitingForChildren` before any child can finish.
+
+4. **Approve merges the unit.** `WorkerHub.ApproveReview` (and the MCP
+   `ReviewTask` approve path): when the approved task has children, run
+   `PlanningMergeOrchestrator` (parent worktree if `Active` + each `Done` child in
+   order), then transition the parent to `Done`. On a child merge conflict, the
+   parent stays in `WaitingForReview` (mirrors current single-task approve-conflict
+   behavior). Retire the `MergeAllPlanning` Hub method + UI button.
+
+5. **Allow cancelling a `WaitingForChildren` parent.** Add `WaitingForChildren` to
+   the `CancelAsync` guard so a parent waiting on children can be cancelled (today it
+   cannot — minor gap).
+
+6. **Docs.** Fix the `WaitingForChildren`-missing drift in
+   `src/ClaudeDo.Data/CLAUDE.md` and `src/ClaudeDo.Worker/CLAUDE.md`, and update the
+   transition diagram + the root `CLAUDE.md` status-flow line to the unified model.
+
+## Out of scope (unchanged)
+
+- Authoring UX: planning session vs `suggest_improvement` stay as two distinct
+  entry points (both already call `CreateChildAsync`).
+- `WorktreeManager.ResolveBaseCommitAsync` base-commit divergence (planning children
+  branch from list HEAD; improvement children from parent head) — left as-is.
+- Sequential-vs-parallel scheduling — already shared infrastructure
+  (`BlockedByTaskId`); planning chains, improvement doesn't. No change.
+
+## Risks / edge cases
+
+- **Ordering on finalize** — parent must be `WaitingForChildren` before the first
+  child can reach terminal. Guaranteed by setting it inside `FinalizePlanningAsync`,
+  which runs before `SetupChainAsync`.
+- **Zero-children planning parent** — must advance to `WaitingForReview`, not stick
+  in `WaitingForChildren`. Explicit branch in `TryAdvanceParentAsync` /
+  `FinalizePlanningAsync`.
+- **Failed/cancelled children** — parent still advances to `WaitingForReview` with
+  the existing `⚠ Children: N failed, M cancelled` annotation; no wedge.
+- **Approve-merge conflict** — keep parent in `WaitingForReview`; surface the
+  conflicting child like the current merge-conflict path.
+- **Existing rows** — planning parents currently sitting at `Idle`+`Finalized` with
+  live children: behavior change is forward-only (new finalizes use the new flow);
+  no migration needed since `Status`/`PlanningPhase` columns already exist.

-Only standalone tasks (`ParentTaskId == null`) route to `WaitingForReview` on success. Planning children go straight to `Done` so the sequential chain (which advances on terminal states) is unaffected. `TaskRunner.HandleSuccess` makes this choice; review transitions live in `TaskStateService` (`SubmitForReviewAsync`, `ApproveReviewAsync`, `RejectToQueueAsync`, `RejectToIdleAsync`, `ClearReviewFeedbackAsync`).
+**Unified parent model.** Every parent — planning *or* improvement — flows
+`… → WaitingForChildren → WaitingForReview → Done`, advanced by the single
+`TaskStateService.TryAdvanceParentAsync` (surfaces any `WaitingForChildren` parent for
+review once all children are terminal; failed/cancelled children are annotated on the
+result, not wedged). A planning parent enters `WaitingForChildren` at
+`FinalizePlanningAsync` (or `WaitingForReview` directly if it has no children); an
+improvement parent enters it from `TaskRunner.HandleSuccess` when its run spawned
+children. Planning/improvement **children** still go straight to `Done` (no individual
+review) — only the parent is reviewed.
+
+**Approve = merge the whole unit.** `ApproveReview`/`review_task` approve, for a task
+that has children, drives `PlanningMergeOrchestrator` (merges the parent worktree if
+Active + each `Done` child in order, sets the parent `Done`, and on a mid-merge
+conflict pauses for `ContinuePlanningMerge`/`AbortPlanningMerge`). Childless tasks use
+`TaskMergeService.ApproveAndMergeAsync`. There is no separate "Merge all" entry —
+approve is the single review+merge action. Review transitions live in `TaskStateService`
+(`SubmitForReviewAsync`, `SubmitForChildrenAsync`, `ApproveReviewAsync`,
+`RejectToQueueAsync`, `RejectToIdleAsync`, `ClearReviewFeedbackAsync`).
 
 ## Planning Flow
 
 `PlanningSessionManager.FinalizeAsync` is the single path:
 
-1. `_state.FinalizePlanningAsync(parent)` flips parent `PlanningPhase` to `Finalized`.
-2. `PlanningChainCoordinator.SetupChainAsync` attaches the `agent` tag to every child, enqueues child[0], and `BlockOn`s child[i] → child[i-1].
-3. The first child is woken automatically; successors unblock as their predecessor reaches a terminal state via `OnChildFinishedAsync`.
+1. `_state.FinalizePlanningAsync(parent)` flips parent `PlanningPhase` to `Finalized` and sets `Status` to `WaitingForChildren` (or `WaitingForReview` if the parent has no children).
+2. `PlanningChainCoordinator.SetupChainAsync(parent, enqueue: false)` establishes the blocked-by chain (`BlockOn`s child[i] → child[i-1]) but **leaves children `Idle`** — finalize never auto-queues. Queueing is a deliberate user action: `QueuePlanAsync` (hub `QueuePlanningSubtasksAsync`, the "Queue plan" button) calls `SetupChainAsync(parent, enqueue: true)`, which sets every non-terminal child `Queued` and re-applies the chain.
+3. Once queued, the first child is woken automatically; successors unblock as their predecessor reaches a terminal state via `OnChildFinishedAsync`.
+
+A child that hits a roadblock (fails, or reports `CLAUDEDO_BLOCKED` roadblocks) does **not** advance the parent — the parent stays in `WaitingForChildren` until every child is terminal. The UI surfaces blocked children on the parent's Session tab (`ChildOutcomes` + a "children need attention" band) so the roadblock is visible without forcing a transition.
 
 `TaskRepository.FinalizePlanningAsync` no longer exists. The `Mark*Async` repository helpers are `internal` — only `TaskStateService` calls them.
