 - Repository pattern — each entity has its own async repository
 - All data operations are async with CancellationToken support

+# ClaudeDo — Avalonia Handoff
+
+## Overview
+
+ClaudeDo is an agent dispatcher for Claude Code: a Windows desktop app that presents background coding agents as tasks. Each task has a title, a list, a git worktree/branch, an agent status (idle / queued / running / review / error), a live session log, and a diff. The UI is organised as **three floating islands** (Lists / Tasks / Details) over a dark "sea" background, Windows-11 style.
+
+The bundled HTML file is a **design reference**, not production code. Your job is to recreate it as a native Avalonia app — match the look, feel, and interaction model, but use idiomatic AXAML, Avalonia controls, and whatever MVVM / ReactiveUI / CommunityToolkit patterns your codebase already uses.
+
+## Fidelity
+
+**High-fidelity.** All colors, typography, spacing, corner radii, shadows, and interaction states are final. Recreate pixel-perfectly using Avalonia primitives. The one exception: motion — CSS animations translate approximately to Avalonia `Transitions` / `Animation`; the durations and easings in `Tokens.axaml` are the intent.
+
+## What's in this package
+
+| File | Purpose |
+|---|---|
+| `Tokens.axaml` | `ResourceDictionary` — colors, brushes, spacing, corner radii, typography, shadows, motion durations. **Merge this first in `App.axaml`.** |
+| `IslandStyles.axaml` | `Styles` — classed styles for Island, Chip, Button, TextBox, TaskRow, AgentStrip, Terminal, ListItem. Depends on `Tokens.axaml`. |
+| `ClaudeDo.html` | The live design reference — open it in a browser to see behavior, hover states, animations, modals. |
+| `ClaudeDo-standalone.html` | Fully offline single-file version (no network). Ship this with the handoff. |
+| `app.jsx`, `islands.jsx`, `modals.jsx`, `icons.jsx`, `data.jsx`, `styles.css` | Source of the reference. Read `styles.css` for any measurement you need to verify; read the JSX for component structure and state transitions. |
+| `ComponentSpec.md` | This file section below — maps every visual element to the AXAML control you should use. |
+
+## How to wire the tokens
+
+In `App.axaml`:
+
+```xml
+<Application.Resources>
+  <ResourceDictionary>
+    <ResourceDictionary.MergedDictionaries>
+      <ResourceInclude Source="avares://YourApp/Design/Tokens.axaml" />
+    </ResourceDictionary.MergedDictionaries>
+  </ResourceDictionary>
+</Application.Resources>
+
+<Application.Styles>
+  <FluentTheme />
+  <StyleInclude Source="avares://YourApp/Design/IslandStyles.axaml" />
+</Application.Styles>
+```
+
+Pack **Inter Tight** (sans) and **JetBrains Mono** (mono) as embedded resources and reference them via `avares://YourApp/Assets/Fonts/#Inter Tight` in `Tokens.axaml` if the system-font fallback isn't good enough.
+
+---
+
+## Window chrome
+
+The reference shows a Windows-11-style app in a chromeless window with a custom title bar and taskbar. For a native Avalonia app, use `SystemDecorations="None"` + `ExtendClientAreaToDecorationsHint="True"` and draw your own title bar, OR use the platform chrome — the islands-over-sea metaphor works either way. The taskbar strip at the bottom of the reference is decorative; drop it.
+
+## Layout
+
+Root window:
+```
+┌─────────────────────────────────────────────────────────┐
+│ TitleBar                                                │
+├─────────────┬──────────────────────────┬────────────────┤
+│ Lists       │ Tasks                    │ Details        │
+│ (260px)     │ (1fr, min 340px)         │ (320px)        │
+│             │                          │ hides <1100px  │
+└─────────────┴──────────────────────────┴────────────────┘
+```
+
+Use a `Grid` with 3 columns: `260,*,320`. Collapse the Details column when `ActualWidth < 1100` via a bound `ColumnDefinition.Width`. Between columns and around the grid, add 14px gap — put each island in a `Border Classes="island"` with `Margin="7"` so you get the island-to-island gap naturally.
+
+Background of the grid cell: apply `DesktopBackgroundBrush` from tokens, plus a subtle radial-gradient overlay via a `Border` with an opacity mask if desired.
+
+---
+
+## Components
+
+### Island (base container)
+
+- `Border Classes="island"`
+- Contents: header section + scrollable body
+- Header: inner `Border Classes="island-header"` with an eyebrow label (mono, uppercase, tracking 1.4) and a title
+- Body: `ScrollViewer` → `StackPanel` or `ItemsControl`
+- All three columns are islands.
+
+### Lists island (left)
+
+- Search box: `TextBox Classes="search"` with left-aligned search icon (PathIcon)
+- Nav items: `ItemsControl` bound to a `Lists` collection
+  - Each item is `Border Classes="list-item"` (toggle `active` class when selected) containing
+    - `PathIcon` (16px)
+    - `TextBlock` (list name, 13px)
+    - `TextBlock` (count, mono 10px, right-aligned, TextFaintBrush)
+- Lists shown: My Day, Important, Planned, Running, Review, Tasks (by project name)
+
+### Tasks island (middle)
+
+Header row:
+- Eyebrow: weekday date ("MONDAY · APR 28")
+- Title: "My Day" (or current list name) — 24px semibold
+- Subtitle: "{N} open · {N} running · {N} in review" — mono 11px TextMute
+- Right side: icon buttons (sort, filter, show-completed toggle)
+
+Add-task row:
+- `TextBox` with placeholder "Add a task…"
+- On Enter: dispatch new task (see ViewModel spec)
+
+Task list:
+- `ItemsControl` → `Border Classes="task-row"` per task
+- Row content: `Grid` with columns `Auto,*,Auto`
+  - Left: `Ellipse Classes="task-check"` (toggles `done` class on completion) — use a `Button` with a templated Ellipse for keyboard support
+  - Middle: `StackPanel` vertical
+    - Title: `TextBlock` 14px, strike-through when done
+    - Meta row: `StackPanel` horizontal with 8px gap, children:
+      - `Border Classes="chip {status}"` (status chip — Running / Review / Error / Queued / Idle)
+      - `Border Classes="chip"` with list name
+      - `Border Classes="chip"` with mono branch name (e.g. `agent/auth-pool`)
+      - `Border Classes="chip"` with diff stats (`+142 −86`)
+      - Live tail of latest agent output when running — use `TextTrimming="CharacterEllipsis"` in a fixed-width container
+  - Right: `Button Classes="icon-btn"` (star)
+- Selection: toggle `selected` class; add a `Rectangle` with `Width=2` as the left accent bar (child of the task-row Border)
+
+### Details island (right)
+
+Shown when a task is selected. Sections, top to bottom:
+
+1. **Header**: task title (editable — `TextBox` with no visible border, `FontSize=18`), list chip, delete icon button
+2. **Agent strip** — `Border Classes="agent-strip {status}"`:
+   - Row 1: status indicator dot + status label ("Running" / "Review" / etc.) + model name ("claude-sonnet-4.5") + turns + tokens + elapsed
+   - Row 2: Worktree path (mono, truncating)
+   - Row 3: Branch → Base ("agent/auth-pool ← main") + commit count + diff stats
+   - Buttons: "Open diff" / "Worktree" / "Stop" (when running) / "Approve & merge" (when review)
+3. **Session output** — `Border Classes="terminal"` with a `ScrollViewer` auto-scrolled to bottom:
+   - Each line is a `TextBlock Classes="log-{kind}"` — kinds: sys, tool, claude, stdout, stderr, done, msg
+   - Below it, a prompt input: `[you]` prefix + `TextBox` to send messages to the agent
+4. **Subtasks** — `ItemsControl` of checkbox + text rows
+5. **Notes** — multi-line `TextBox`, `AcceptsReturn="True"`
+6. **Metadata** — created date, last activity, tags (readonly chips)
+
+### Modals
+
+Two modals in the reference: **Diff** and **Worktree**. Use `Window` with `WindowStartupLocation="CenterOwner"` and a scrim (`Border` over the main window with `Background="#BF030504"` + blur via `OpacityMask` or a child `Grid`). Or use `Dialog` if your shell has one.
+
+**Diff modal**: left sidebar of files (each with `+N −N` stats), right pane with syntax-colored hunks. Use two `ListBox`-style panels side-by-side. For lines: `del` = red tinted, `add` = green tinted, `ctx` = neutral. Left gutter columns: old line number, new line number, sign (`+` / `−` / space).
+
+**Worktree modal**: folder tree with `M` (modified) / `A` (added) badges. `TreeView` fits naturally.
+
+### Status mapping
+
+| Status | Chip color | Icon | When |
+|---|---|---|---|
+| idle | TextMute | circle | Task created, agent not dispatched |
+| queued | Sage | dots | Agent queued behind others |
+| running | Accent (moss) | pulse dot | Agent actively working |
+| review | Peat | eye | Agent finished; awaiting approval |
+| error | Blood | exclamation | Agent failed |
+
+---
+
+## State & interactions
+
+### Task model (MVVM)
+
+```csharp
+public class TaskItem : ReactiveObject {
+    string Id, Title, List;
+    bool Done, Starred, MyDay;
+    DateTime? Due, Created;
+    string Notes;
+    List<string> Tags;
+    List<SubTask> Subtasks;
+    AgentState Agent;    // null if not dispatched
+}
+
+public class AgentState : ReactiveObject {
+    AgentStatus Status;            // Idle | Queued | Running | Review | Error
+    string Model, Worktree, Branch, BaseBranch;
+    int Commits, Turns, Tokens;
+    DiffStats Diff;                // Files, Additions, Deletions
+    DateTime? StartedAt, FinishedAt;
+    ObservableCollection<LogLine> Log;
+}
+```
+
+### Key interactions
+
+- **Toggle done**: click checkbox → flip `Done`, animate strike-through (0.2s ease-out)
+- **Select task**: click row → set `SelectedTask`; details island rebinds
+- **Add task**: Enter in the add-task textbox → prepend new task; scroll list to top; 0.3s fade-in animation on the new row (use `Animation` with opacity + `TranslateTransform.Y`)
+- **Dispatch agent**: "Start agent" button in Details → sets `Agent.Status = Running`, appends sys log "Agent dispatched."
+- **Stop agent**: → `Status = Review` (or `Error` on failure), appends sys log
+- **Send prompt**: Enter in prompt input → append `[you] {msg}` to log
+- **Open diff / worktree**: opens modal; Esc closes
+
+### Keyboard
+
+- `/` focuses the search box in the Lists island
+- `Cmd/Ctrl+N` focuses add-task
+- `Space` toggles done on selected row
+- `Esc` closes any open modal
+
+### Animations
+
+- Task-row hover: background transition 0.1s
+- Task-row add: 0.3s opacity + slight Y-slide
+- Task-row complete: 0.25s strike-through + fade to `done` styling
+- Running status dot: infinite pulse (opacity 0.4 → 1.0, 1.2s)
+- Modal open: 0.18s opacity + scale (0.98 → 1.0)
+- Backdrop: 0.15s opacity fade
+
+### Responsive
+
+- `< 1100px`: hide Details island; details open as a transient panel or modal on task select
+- `< 780px`: hide Lists island; use a hamburger drawer
+
+---
+
+## Design tokens (reference)
+
+All final values live in `Tokens.axaml`. Reproduced here for reading:
+
+**Surfaces**: `#0A0E0C` void · `#0D1311` deep · `#161D1A` surface · `#1C2422` surface-2 · `#222B28` surface-3 · `#2A3330` line
+
+**Text**: `#E4EBE4` primary · `#9AA8A0` dim · `#6B7973` mute · `#4A5550` faint
+
+**Accents**: `#7C9166` moss (primary) · `#8B9D7A` sage · `#D4A574` peat · `#C87060` blood
+
+**Spacing**: 4, 8, 12, 14 (island gap), 18, 24
+
+**Corner radii**: 14 (island) · 12 (modal) · 10 (chip) · 8 (task row, input) · 6 (button) · 999 (pill)
+
+**Typography**: Inter Tight (sans), JetBrains Mono (mono). Scale: 10 (eyebrow) / 11 (mono, micro) / 13 (body) / 14 (task title) / 18 (h3) / 24 (h2) / 32 (h1)
+
+**Shadows**:
+- Island: `0 20 40 #59000000, 0 2 4 #4D000000`
+- Modal: `0 40 80 #B2000000`
+
+**Motion**: 120ms (fast) / 180ms (base) / 300ms (slow). Easing: cubic-bezier(0.4, 0, 0.2, 1) — use Avalonia's `CubicEaseOut` or a custom `SplineEasing`.
+
+---
+
+## Acceptance checklist
+
+- [ ] Three-island layout with correct spacing and grid collapse at <1100px
+- [ ] Lists sidebar with icons, counts, search, active state
+- [ ] Task rows with checkbox, title, meta chips (status/list/branch/diff), star
+- [ ] Task selection updates Details island
+- [ ] Agent strip shows status, model, turns, tokens, elapsed, worktree, branch
+- [ ] Session terminal renders all log kinds with distinct colors, auto-scrolls, accepts prompt input
+- [ ] Diff modal with file sidebar and tinted add/del lines
+- [ ] Worktree modal with M/A badges
+- [ ] Status chip tints match the spec
+- [ ] Fonts: Inter Tight + JetBrains Mono packed and applied
+- [ ] Motion: task add/toggle, running pulse, modal open, hover transitions
+- [ ] Keyboard shortcuts wired

+# Logic Bug Fixes 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:** Fix confirmed logic bugs across Worker, App/Ui, and Installer found in the 2026-04-17 three-agent review.
+
+**Architecture:** Each bug is an isolated change to one or two files. Group by priority (Critical → High → Medium → Info). TDD where the bug is observable via xUnit integration test (Worker, Data); for UI/Installer bugs without test harness, do a focused manual repro and guard with a regression comment referencing the commit.
+
+**Tech Stack:** .NET 8, Avalonia 12, CommunityToolkit.Mvvm, EF Core + SQLite, SignalR, xUnit (Worker tests only).
+
+---
+
+## File Map
+
+**Worker:**
+- Modify: `src/ClaudeDo.Worker/Hub/WorkerHub.cs` — remove premature `RunCreated` broadcast
+- Modify: `src/ClaudeDo.Worker/Runner/TaskRunner.cs` — emit `RunCreated` after run row insert
+- Modify: `src/ClaudeDo.Worker/Services/QueueService.cs` — add slot-collision guard on `RunNow`/`ContinueTask`
+- Modify: `src/ClaudeDo.Worker/Runner/ClaudeArgsBuilder.cs` — extend quoting to cover whitespace/newline
+- Test: `tests/ClaudeDo.Worker.Tests/ClaudeArgsBuilderTests.cs` — regression for newline in system prompt
+- Test: `tests/ClaudeDo.Worker.Tests/QueueServiceSlotGuardTests.cs` — regression for RunNow-while-queued
+
+**Ui:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/TaskListViewModel.cs` — guard nullability in `AddTask`, harden `OnTaskUpdated`
+- Modify: `src/ClaudeDo.Ui/ViewModels/TaskDetailViewModel.cs` — defer `_taskId` assignment until after cancel check
+- Modify: `src/ClaudeDo.Ui/ViewModels/TaskEditorViewModel.cs` — init TCS before dialog shown
+
+**Installer:**
+- Modify: `src/ClaudeDo.Installer/Steps/RegisterServiceStep.cs` — remove inline start; reject CurrentUser without password
+- Modify: `src/ClaudeDo.Installer/Steps/DownloadAndExtractStep.cs` — rename-before-extract rollback
+- Modify: `src/ClaudeDo.Installer/Core/UninstallRunner.cs` — add `removeAppData` parameter
+- Modify: `src/ClaudeDo.Installer/Steps/WriteConfigStep.cs` — expand `~` in `UiDbPath`
+- Verify: `src/ClaudeDo.Installer/App.xaml.cs` — confirm Avalonia vs WPF usings
+
+---
+
+## Critical
+
+### Task 1: Worker — fix `RunCreated` broadcast ordering (W1)
+
+Bug: `WorkerHub.RunNow` fires `RunCreated` before the run row is inserted by `RunOnceAsync`. UI can receive an event for a row that does not yet exist.
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Hub/WorkerHub.cs:35-50`
+- Modify: `src/ClaudeDo.Worker/Runner/TaskRunner.cs:234-256` (`RunOnceAsync`)
+
+- [ ] **Step 1: Remove premature broadcast from WorkerHub**
+
+In `src/ClaudeDo.Worker/Hub/WorkerHub.cs`, replace the body of `RunNow`:
+
+```csharp
+public async Task RunNow(string taskId)
+{
+    try
+    {
+        await _queue.RunNow(taskId);
+    }
+    catch (InvalidOperationException)
+    {
+        throw new HubException("override slot busy");
+    }
+    catch (KeyNotFoundException)
+    {
+        throw new HubException("task not found");
+    }
+}
+```
+
+- [ ] **Step 2: Emit `RunCreated` inside `RunOnceAsync` after row insert**
+
+In `src/ClaudeDo.Worker/Runner/TaskRunner.cs`, find `RunOnceAsync`. After the `runRepo.AddAsync(run, ct);` block (~line 256), add:
+
+```csharp
+await _broadcaster.RunCreated(taskId, runNumber, isRetry);
+```
+
+Then remove the existing `await _broadcaster.RunCreated(task.Id, 2, true);` on line 128 (inside the auto-retry block in `RunAsync`) and the `await _broadcaster.RunCreated(taskId, nextRunNumber, false);` on line 219 (in `ContinueAsync`), since `RunOnceAsync` now broadcasts unconditionally.
+
+- [ ] **Step 3: Build and run Worker tests**
+
+Run: `dotnet build ClaudeDo.slnx && dotnet test tests/ClaudeDo.Worker.Tests`
+Expected: all existing tests pass.

+### Task 2: Ui — harden `OnTaskUpdated` against async void crash (U2)
+
+Bug: `TaskListViewModel.OnTaskUpdated` is `async void` with no try/catch. A DB error escapes to `TaskScheduler.UnobservedTaskException` and can crash the process.
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/TaskListViewModel.cs:328-332`
+
+- [ ] **Step 1: Wrap handler body in try/catch**
+
+Replace the existing method with:
+
+```csharp
+private async void OnTaskUpdated(string taskId)
+{
+    if (CurrentListId is null) return;
+    try
+    {
+        await RefreshSingleAsync(taskId);

+### Task 3: Installer — reject CurrentUser service registration without password (I1)
+
+Bug: `RegisterServiceStep` passes `obj=.\<user>` to `sc.exe create` with no `password=`. SCM rejects it with exit 5 / 1069 and the user gets an opaque error.
+
+**Files:**
+- Modify: `src/ClaudeDo.Installer/Steps/RegisterServiceStep.cs`
+
+- [ ] **Step 1: Read the current file**
+
+Read `src/ClaudeDo.Installer/Steps/RegisterServiceStep.cs` to confirm the exact shape of the `obj=` branch and the outer `StepResult` return.
+
+- [ ] **Step 2: Replace CurrentUser branch with early failure**
+
+Where the step builds `obj=".\\<username>"` for the `CurrentUser` account option, replace it with:
+
+```csharp
+if (ctx.ServiceAccount == ServiceAccountType.CurrentUser)
+{
+    return StepResult.Fail(
+        "Service cannot run as Current User without a password. " +
+        "Select 'Local System' or extend ServicePage to capture a password.");
+}
+```
+
+Keep the `LocalSystem` branch (which passes `obj= LocalSystem` with no password requirement) unchanged.
+
+- [ ] **Step 3: Build**
+
+Run: `dotnet build ClaudeDo.slnx`
+Expected: build succeeds.

+### Task 4: Worker — guard slot collision on `RunNow` and `ContinueTask` (W2)
+
+Bug: Queue slot and override slot have no guard against operating on the same `taskId`. `TaskRunner.MarkRunningAsync` can overwrite `started_at`.
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Services/QueueService.cs:59-115`
+- Test: `tests/ClaudeDo.Worker.Tests/QueueServiceSlotGuardTests.cs` (new)
+
+- [ ] **Step 1: Write failing test**
+
+Create `tests/ClaudeDo.Worker.Tests/QueueServiceSlotGuardTests.cs`:
+
+```csharp
+using ClaudeDo.Data.Models;
+using ClaudeDo.Worker.Services;
+using Xunit;
+

+        await Assert.ThrowsAsync<InvalidOperationException>(() => queue.RunNow(task.Id));
+    }
+}
+```
+
+(Helpers `WorkerTestBase`, `SeedAgentTaskAsync`, `SeedListAsync`, `WaitForActiveSlotAsync` exist in the test project — follow the pattern from existing tests.)
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests --filter "FullyQualifiedName~QueueServiceSlotGuardTests"`
+Expected: FAIL — currently `RunNow` succeeds and creates a duplicate slot.
+
+- [ ] **Step 3: Add guard in `RunNow`**
+
+In `src/ClaudeDo.Worker/Services/QueueService.cs`, inside the `lock (_lock)` block in `RunNow` (~line 69), add before the existing override check:
+
+```csharp
+if (_queueSlot?.TaskId == taskId)
+    throw new InvalidOperationException("task is already running in queue slot");
+```
+
+- [ ] **Step 4: Add same guard in `ContinueTask`**
+
+In the `lock (_lock)` block in `ContinueTask` (~line 97), add:
+
+```csharp
+if (_queueSlot?.TaskId == taskId)
+    throw new InvalidOperationException("task is already running in queue slot");
+```
+
+- [ ] **Step 5: Run tests**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests`
+Expected: PASS.
+
+- [ ] **Step 6: Commit**
+
+```bash

+### Task 5: Worker — quote CLI args with tab/newline/carriage-return (W3)
+
+Bug: `ClaudeArgsBuilder.Escape` only quotes on space/quote. System prompts with newlines pass through unquoted and corrupt the argument list.
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Runner/ClaudeArgsBuilder.cs:56-64`
+- Test: `tests/ClaudeDo.Worker.Tests/ClaudeArgsBuilderTests.cs` (new or existing)
+
+- [ ] **Step 1: Write failing test**
+
+If `ClaudeArgsBuilderTests.cs` does not exist, create it:
+
+```csharp

+}
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests --filter "FullyQualifiedName~ClaudeArgsBuilderTests"`
+Expected: FAIL — newline is passed through unquoted.
+
+- [ ] **Step 3: Extend `Escape` condition and escape newline/tab**
+
+In `src/ClaudeDo.Worker/Runner/ClaudeArgsBuilder.cs`, replace `Escape`:
+
+```csharp

+### Task 6: Installer — remove inline service start from `RegisterServiceStep` (I2)
+
+Bug: `RegisterServiceStep` calls `sc.exe start` inline. `StartServiceStep` exists separately. If the update path ever wires both, the service is started twice.
+
+**Files:**
+- Modify: `src/ClaudeDo.Installer/Steps/RegisterServiceStep.cs`
+- Modify: `src/ClaudeDo.Installer/App.xaml.cs` (pipeline) — ensure `StartServiceStep` is in the fresh-install pipeline
+
+- [ ] **Step 1: Read current pipeline wiring in App.xaml.cs**
+
+Read `src/ClaudeDo.Installer/App.xaml.cs` around line 112 to confirm the list of steps passed into `InstallerService`.
+
+- [ ] **Step 2: Remove inline `sc.exe start` from RegisterServiceStep**
+
+Delete the block (~lines 72-77) that runs `sc.exe start <service>` when `ctx.AutoStart == true`.
+
+- [ ] **Step 3: Add `StartServiceStep` to the fresh-install pipeline if missing**
+
+In `App.xaml.cs`, append `new StartServiceStep(...)` after `RegisterServiceStep` in the step list. Gate its execution internally on `ctx.AutoStart` (it already handles exit code 1056).
+

+### Task 7: Installer — rollback-safe extract in `DownloadAndExtractStep` (I3)
+
+Bug: Old `app/` and `worker/` are deleted before extraction. If extraction throws, user is left with no binaries and no recovery path.
+
+**Files:**
+- Modify: `src/ClaudeDo.Installer/Steps/DownloadAndExtractStep.cs:70-95`
+
+- [ ] **Step 1: Read the current delete/extract sequence**
+
+Read `src/ClaudeDo.Installer/Steps/DownloadAndExtractStep.cs` around lines 70-95 to identify the exact `Directory.Delete` and `ZipFile.ExtractToDirectory` calls and which `ctx` paths they reference.
+
+- [ ] **Step 2: Replace delete-before-extract with rename-then-commit**
+
+Wrap the delete+extract block:

+### Task 8: Installer — gate `~/.todo-app` deletion behind explicit consent (I4)
+
+Bug: Uninstaller always deletes user data (db, logs, configs). Reinstalling a different version silently destroys all tasks.
+
+**Files:**
+- Modify: `src/ClaudeDo.Installer/Core/UninstallRunner.cs:60-80`
+- Modify: `src/ClaudeDo.Installer/Views/UninstallPage.xaml(.cs)` (or equivalent) — add a checkbox

+- [ ] **Step 1: Read `UninstallRunner.RunAsync` signature**
+
+Read `src/ClaudeDo.Installer/Core/UninstallRunner.cs` around lines 1-90 to get current signature.
+
+- [ ] **Step 2: Add `removeAppData` parameter to `RunAsync`**
+
+Change signature to:
+
+```csharp
+public async Task<UninstallResult> RunAsync(bool removeAppData, CancellationToken ct = default)
+```
+
+Guard the deletion:
+
+```csharp
+if (removeAppData)

+
+- [ ] **Step 3: Wire a "Remove user data" checkbox on the uninstall page**
+
+In the uninstall view/VM, add `[ObservableProperty] private bool _removeAppData;` (default `false`) and pass it into `RunAsync(RemoveAppData)`.

+### Task 10: Ui — defer `_taskId` assignment in `TaskDetailViewModel.LoadAsync` (U3)
+
+Bug: `_taskId = taskId` is set at line 87, before the previous `_loadCts` is cancelled. If load is cancelled, `_taskId` has been clobbered but `HasWorktree` / `CanWorktreeAction` still reflect the previous task.
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/TaskDetailViewModel.cs:76-90`

+### Task 11: Ui — initialize TCS before dialog shown in `TaskEditorViewModel` (U4)
+
+Bug: `ShowAndWaitAsync` creates a fresh `_tcs` only when called. If `Save` fires before `ShowAndWaitAsync` (possible if `ShowDialogAsync` is ever awaited), the result is dropped.
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/TaskEditorViewModel.cs:72-80, 260-264`
+- Modify: `src/ClaudeDo.Ui/ViewModels/ListEditorViewModel.cs` (same pattern — apply identically)

+{
+    _tcs = new TaskCompletionSource<TaskEntity?>();
+    _editId = null;

+- [ ] **Step 2: Remove re-assignment in `ShowAndWaitAsync`**
+
+```csharp

+
+### Task 13: Installer — verify App.xaml.cs WPF-vs-Avalonia usings (I6)
+
+Suspected bug: `src/ClaudeDo.Installer/App.xaml.cs` uses `System.Windows` (WPF). If the project is Avalonia, wrong base class is inherited.
+
+**Files:**
+- Read: `src/ClaudeDo.Installer/App.xaml.cs`
+- Read: `src/ClaudeDo.Installer/ClaudeDo.Installer.csproj`
+
+- [ ] **Step 1: Inspect the csproj for the UI framework SDK**
+
+Read `src/ClaudeDo.Installer/ClaudeDo.Installer.csproj` and look for `<UseWPF>` or `<PackageReference Include="Avalonia" ... />`.
+
+- [ ] **Step 2: Decision fork**
+
+- If WPF (`<UseWPF>true</UseWPF>`): `System.Windows` is correct. Stop. No fix needed.
+- If Avalonia: replace `using System.Windows;` with `using Avalonia;` and change `Application` / `StartupEventArgs` / `ExitEventArgs` to Avalonia equivalents (`Avalonia.Application`, lifetime `OnFrameworkInitializationCompleted`).
+
+- [ ] **Step 3: Build**
+
+Run: `dotnet build ClaudeDo.slnx`
+Expected: build succeeds.
+
+- [ ] **Step 4: Commit only if changed**
+
+```bash
+git add src/ClaudeDo.Installer/App.xaml.cs
+git commit -m "fix(installer): use Avalonia application base class"

+
+## Out of Scope
+
+Deferred / not fixed in this plan:
+- `TryScheduleTrampolineDelete` PID-less delay (I6 in review, low severity) — `ping -n 3` is flaky but rarely hit
+- `AvailableAgents` being `List<T>` instead of `ObservableCollection<T>` (U5/info) — current `OnPropertyChanged` pattern works; revisit only if a bug manifests
+
+---
+
+## Self-Review Notes
+
+- Every Worker bug (W1–W3) has a regression test or tested path.
+- Every UI fix names the exact file:line and shows the replacement snippet.
+- Installer Task 3 (I1) does not guess a password-capture UI — it deliberately returns `StepResult.Fail`, leaving the UX change for a later plan.
+- Task 13 (I6) is a conditional task with a decision fork; no speculative rewrite.
+- Types are consistent: `RunCreated(taskId, runNumber, isRetry)` in Task 1 matches the existing `HubBroadcaster.RunCreated` signature used at `TaskRunner.cs:128,219`.

+# UI Polish — Design Parity Follow-up
+
+> Follow-up to the islands rewrite. Closes visible gaps between the current state and the handoff mock. Execute with subagent-driven development; phases B/C/D can run in parallel.
+
+**Goal:** Bring the rewrite to pixel-level parity with `docs/UI Rewrite/design_handoff_claudedo/ClaudeDo-standalone.html`.
+
+**Tech stack:** Avalonia 12, CommunityToolkit.Mvvm. No new dependencies.
+
+**Reference files:**
+- Source of truth: `docs/UI Rewrite/design_handoff_claudedo/ClaudeDo-standalone.html`
+- CSS measurements: `docs/UI Rewrite/design_handoff_claudedo/styles.css`
+- JSX component structure: `docs/UI Rewrite/design_handoff_claudedo/islands.jsx`, `app.jsx`
+- Tokens: `src/ClaudeDo.Ui/Design/Tokens.axaml`
+- Styles: `src/ClaudeDo.Ui/Design/IslandStyles.axaml`
+
+**Rules for all phases:**
+- Use existing token brushes (`MossBrush`, `PeatBrush`, `AccentSoftBrush`, etc.) — do NOT hard-code hex.
+- Use `Classes="foo"` + selectors in `IslandStyles.axaml` for reusable styling; inline AXAML setters for one-off values only.
+- Icons: use `Projektion.Avalonia` `PathIcon` with `Data="{StaticResource IconKey}"`. Define new `StreamGeometry` resources in `IslandStyles.axaml` under an `<Icons>` section when needed. Pull the SVG paths from the JSX reference.
+- Read the relevant JSX + CSS file in the handoff before implementing each component — those are the source of truth for exact measurements/paddings/colors.
+- Do not touch the data layer, Worker, SignalR, or command wiring. This is a view/style-only pass.

+
+## Phase A — Shell + title bar (sequential, run first)
+
+One subagent. Small blast radius; prerequisite for the visual "feel."
+
+### Task A1 — Custom title bar
+
+**Files:**
+- `src/ClaudeDo.Ui/Views/MainWindow.axaml` + `.axaml.cs`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (add title-bar styles + window-control icon-button style)
+
+- [ ] Replace the current title bar Grid with a 3-section layout:
+  - Left: brand block — checkbox-style green glyph + `CLAUDEDO` (mono, uppercase, tracking 1.4, 11px) + separator dot + current-list name eyebrow-style (mono uppercase, `TextDim`). Bind the list name to `Shell.Lists.SelectedList.Name.ToUpperInvariant()`.
+  - Middle: draggable strip (`PointerPressed → BeginMoveDrag`).
+  - Right: three frameless icon buttons (minimize / maximize-restore / close). Close button hover turns `BloodBrush`. Use `PathIcon` with inline `StreamGeometry` for the Lucide-style icons: `Minus`, `Square`, `X` — the exact SVG `d` strings are in `icons.jsx`.
+- [ ] Title bar height: 36px, background `DeepBrush`, bottom border 1px `LineBrush`.
+- [ ] Remove the character glyphs currently used for the window controls (`—`, `▢`, `✕`) — use PathIcons instead.
+- [ ] Commit: `style(ui): custom title bar with brand and window controls`
+
+### Task A2 — Background + island shadow
+
+**Files:**
+- `src/ClaudeDo.Ui/Views/MainWindow.axaml` (background layer)
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (island shadow adjust)
+
+- [ ] Under the three-island Grid, add a `Border` filling the whole row with a subtle radial gradient from `DeepBrush` (center) to `VoidBrush` (edges). Use a `RadialGradientBrush` with 2 stops; keep opacity light.
+- [ ] In `IslandStyles.axaml`, bump the `Border.island` `BoxShadow` to match the token `IslandShadow` value exactly (`0 20 40 #59000000, 0 2 4 #4D000000`). Verify by inspecting the current style — if it's already set, no-op.
+- [ ] Commit: `style(ui): background gradient and stronger island shadow`
+
+---
+
+## Phase B — Lists island polish (parallel with C, D)
+
+### Task B1 — Icon geometries + eyebrow rename + sections
+
+**Files:**
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (add `StreamGeometry` icon resources at the top)
+- `src/ClaudeDo.Ui/ViewModels/Islands/ListsIslandViewModel.cs` (map `IconKey` strings → resource keys, add section grouping)
+- `src/ClaudeDo.Ui/Views/Islands/ListsIslandView.axaml`
+
+- [ ] Extract the SVG path `d` strings from `icons.jsx` for: `Sun`, `Activity` (pulse), `Star`, `Calendar`, `Eye`, `Inbox`, `Folder`, `Search`, `Plus`, `MoreHorizontal`. Define each as an `x:Key="Icon.Sun"` `StreamGeometry` in `IslandStyles.axaml`.
+- [ ] Change Lists eyebrow from `WORKSPACE` to `NAVIGATOR`.
+- [ ] Add two section-header rows in the ItemsControl: `SMART LISTS` (above items of `Kind=Smart` + `Virtual`) and `MY LISTS` (above items of `Kind=User`). Simplest approach: two separate `ItemsControl`s bound to filtered subsets; or wrap items in a `CollectionViewSource` grouping. Pick the simplest working approach.
+- [ ] Per-item icon: bind `PathIcon Data="{DynamicResource Icon.{IconKey}}"` via a tiny `IconGeometryConverter` (takes `IconKey` string → looks up resource). Icon color: `TextMute` default; `AccentBrush` (moss) when `IsActive`.
+- [ ] User-list items: use a 6px circle with `MossBrush` / `PeatBrush` / `SageBrush` dot instead of folder icon (map per list index mod colors, or single color if simpler).
+- [ ] Active state: remove solid fill. Use `AccentSoftBrush` (~10% moss) + left 2px accent bar + `AccentBrush` icon + `TextBrush` text.
+- [ ] Commit: `style(ui): lists icons, section headers, active state`
+
+### Task B2 — Search bar + keyboard hint + footer buttons
+
+**Files:**
+- `src/ClaudeDo.Ui/Views/Islands/ListsIslandView.axaml`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (search style + kbd chip style)
+
+- [ ] Search `TextBox`: wrap in a `Grid ColumnDefinitions="Auto,*,Auto"` — left `PathIcon Data="{Icon.Search}"` (14px, `TextFaint`), middle TextBox, right `Border Classes="kbd"` with `⌘K` (or `Ctrl K` on Win). The `kbd` chip: mono 10px, `Surface2` bg, `LineBrush` border, padding `6,2`, radius 4.
+- [ ] Under the items list, add:
+  - `+ New list` button — plain icon+text row, `PathIcon Data="{Icon.Plus}"`, hover tint.
+  - User profile row — avatar circle (initials fallback, seed from `Environment.UserName`), name (`Environment.UserName`), subtitle `{MachineName} / local` mono dim, right `PathIcon Data="{Icon.MoreHorizontal}"`.
+- [ ] Commit: `style(ui): lists search icon, kbd hint, footer actions`
+
+---
+
+## Phase C — Tasks island polish (parallel with B, D)
+
+### Task C1 — Header + add-task row styling
+
+**Files:**
+- `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs` (subtitle format, header toolbar properties)
+- `src/ClaudeDo.Ui/Views/Islands/TasksIslandView.axaml`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (kbd-enter, add-task row)
+
+- [ ] Subtitle format: change from `{open} open · {running} running · {review} in review` to `{Weekday}, {Month} {Day} · {open} open` to match the mock. Keep the running/review counts visible but move them into a right-aligned mono pill row next to the title (or drop if cleaner).
+- [ ] Eyebrow: keep current `MONTAG · APR. 20` pattern. Title remains list name.
+- [ ] Right-side icon toolbar: three `Button Classes="icon-btn"` — `Sort` icon, `Eye` icon (toggle completed), `MoreHorizontal`. Icons: pull paths from `icons.jsx`. Wire `Eye` to an `IsShowingCompleted` observable (persist in a private field for now; no DB change).
+- [ ] Add-task row: wrap the `TextBox` in a `Border` with `Surface2` bg, rounded 8px, 14px padding. Prepend a circular `PathIcon Data="{Icon.Plus}"` (20px circle, `Surface3` bg). Append a `Border Classes="kbd"` with `ENTER` text (only visible when `NewTaskTitle` has focus — bind visibility to `TextBox.IsFocused`).
+- [ ] Commit: `style(ui): tasks header toolbar and add-task row`
+
+### Task C2 — Task row chips + states
+
+**Files:**
+- `src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs` (expose a few more flags: `IsOverdue`, `Tags`, `StepsCount`, `StepsCompleted`)
+- `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (chip variants, selected accent, done state, live-tail meter)
+
+- [ ] Chip set per row (ItemsControl or StackPanel):
+  - Status chip (already present) — ensure color maps per Status → token brush (idle/queued/running/review/error).
+  - List chip — small colored bullet (6px circle in `MossBrush` or similar) + list name.
+  - Branch chip — `PathIcon Data="{Icon.GitBranch}"` (12px) + branch name (mono 10px).
+  - Diff chip — `+N` moss + ` ` + `−M` blood.
+  - Tags — one chip per tag (`#refactor` style, `Surface2` bg, mono 10px, `TextDim`).
+- [ ] Selected state: add 2px `AccentBrush` left border on the row Border when `IsSelected=true` (style selector `Border.task-row.selected`). Background shifts to `AccentSoftBrush`.
+- [ ] Done state: strike-through title + fade opacity to 0.5. Add `Border.task-row:has(.done)` equivalent via the existing `Done` binding — simpler: a `TextBlock` style selector that flips `TextDecorations`.
+- [ ] Live-tail row (only visible when `Status == Running` and `LiveTail != null`): a `Border` under the chip row with mono 11px ellipsized text + a slim 3px progress `Rectangle` with `MossBrush`. For now the progress is static 30% — wire it to a future `ProgressFraction` property (leave as 0.3 fallback).
+- [ ] Ensure `task-row` Border has `Transitions` for `Background` + `Margin` (smooth hover + select).
+- [ ] Commit: `style(ui): task row chip set, selected/done states, live tail`
+
+### Task C3 — Section dividers (OVERDUE / TASKS / COMPLETED)
+
+**Files:**
+- `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs` (group the ObservableCollection into sections)
+- `src/ClaudeDo.Ui/Views/Islands/TasksIslandView.axaml` (group headers)
+
+- [ ] Add grouping: transform `Items` into three sub-collections:
+  - `OverdueItems` — tasks with `ScheduledFor < Today` and not Done.
+  - `OpenItems` — remaining not-Done tasks.
+  - `CompletedItems` — tasks with `Done=true`.
+- [ ] Expose as three `ObservableCollection<TaskRowViewModel>` on the VM. Recompute inside `LoadForList`.
+- [ ] View: three `ItemsControl`s stacked in a `StackPanel`, each preceded by a section header `TextBlock` — `OVERDUE` (only if non-empty), `TASKS`, `COMPLETED · {N}`. Eyebrow style, `TextFaint`.
+- [ ] Commit: `style(ui): task section dividers overdue/tasks/completed`
+
+---
+
+## Phase D — Details island polish (parallel with B, C)
+
+### Task D1 — Header + task row restyle
+
+**Files:**
+- `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs` (expose `TaskIdBadge` like `#T1`, computed from task id prefix)
+- `src/ClaudeDo.Ui/Views/Islands/DetailsIslandView.axaml`
+
+- [ ] Top header block:
+  - Eyebrow `LOGBOOK` + right-aligned `#T{shortId}` badge (first 3 hex chars of `Task.Id`, mono `TextFaint`).
+  - Title: keep editable title `TextBox` but reduce size and match mock.
+- [ ] Under header, a new "task strip" row: `Ellipse` checkbox (bound to `Task.Done` toggle) + title + right-aligned star button. This is separate from the editable title (mock shows both title as editable heading AND a task-row-style strip with check/star).
+- [ ] Commit: `style(ui): details header with logbook eyebrow and task-id badge`
+
+### Task D2 — Agent strip v2
+
+**Files:**
+- `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs` (add `Turns`, `TokensFormatted`, `ElapsedFormatted`, `DiffAdditions`, `DiffDeletions`, `CommitsOnBranch` if not present — most exist)
+- `src/ClaudeDo.Ui/Views/Islands/AgentStripView.axaml`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (diff meter bar style)
+
+- [ ] Layout (three rows):
+  - Row 1: pulsing status dot + status label (`RUNNING` etc.) + mono model name + right-aligned stop button (only visible when Running).
+  - Row 2: `WORKTREE` section label + worktree path mono, with a copy-to-clipboard `PathIcon Data="{Icon.Copy}"` button at the end.
+  - Row 3: Branch line — `PathIcon Data="{Icon.GitBranch}"` + branch mono + arrow `←` + `main` + commits count chip.
+  - Row 4: `DIFF` label + `+{additions}` (moss) + `−{deletions}` (blood) + a slim 4px progress-meter `Rectangle` showing additions vs deletions ratio (moss-filled portion).
+- [ ] Action buttons row: `Open diff`, `Worktree`, external-link `→` (opens file:// to worktree path in OS explorer).
+- [ ] Agent strip should use `AgentStripStyle.Classes` bound to the running status so colors shift.
+- [ ] Commit: `style(ui): agent strip with worktree panel and diff meter`
+
+### Task D3 — Session terminal styling
+
+**Files:**
+- `src/ClaudeDo.Ui/Views/Islands/SessionTerminalView.axaml`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (terminal header, log-line columns, `LIVE` chip)
+- `src/ClaudeDo.Ui/ViewModels/Islands/LogLineViewModel.cs` (add `TimestampFormatted` property)
+
+- [ ] Top bar of the terminal `Border`: three colored dots (red/yellow/green, 8px `Ellipse`) + `claude-session · {branch}` mono text + right-aligned `LIVE` chip (moss bg, white text, pulsing animation when a task is actively running).
+- [ ] Log lines: two-column layout — timestamp (mono 10px, `TextFaint`, fixed 70px width) + kind marker (e.g. `TOOL`, `CLAUDE`, `OUT`) + text. Kind marker uses attribute selector `[Tag=log-tool]`, color-mapped.
+- [ ] Line number/timestamp: add `TimestampFormatted` to `LogLineViewModel` populated as `DateTime.Now.ToString("HH:mm:ss")` on construction. (If real timestamps arrive via SignalR later, swap source.)
+- [ ] Ensure auto-scroll still works (existing logic).
+- [ ] Commit: `style(ui): session terminal header, line columns, LIVE chip`
+
+### Task D4 — Subtasks, notes, metadata footer
+
+**Files:**
+- `src/ClaudeDo.Ui/Views/Islands/DetailsIslandView.axaml`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (subtask row style)
+- `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs` (delete-task command, close-detail command)
+
+- [ ] Subtasks: each row is a compact `Border` with rounded 6px, hover background. Check is an `Ellipse` matching the task-row style (not default WinForms-style CheckBox). Completed items get strike-through + fade.
+- [ ] Notes `TextBox`: `Surface2` bg, 12px padding, watermark `Notes...`, auto-saves on `LostFocus` (call repository `Update`).
+- [ ] Bottom metadata bar (sticky at the bottom of the Details island — anchor via `DockPanel.Dock="Bottom"`):
+  - Left: `PathIcon Data="{Icon.Trash}"` delete button (prompts confirmation before calling `TaskRepository.DeleteAsync`).
+  - Middle: `Created {Month Day}` mono `TextFaint`.
+  - Right: close-details `PathIcon Data="{Icon.X}"` (clears `SelectedTask` on `TasksIslandViewModel`).
+- [ ] Commit: `style(ui): subtasks, notes, details metadata footer`

+
+## Execution order
+
+```
+Phase A (A1 → A2)  [sequential, 1 subagent]
+   ↓
+Phase B, C, D       [parallel, 3 subagents, one per phase]
+   ↓
+Final build + smoke
+```
+
+Phase A is sequential because it touches `MainWindow.axaml` and `IslandStyles.axaml` root setup.
+Phases B, C, D each own a distinct island. Only potential conflict: all three add icon geometries to `IslandStyles.axaml`. Mitigation: Phase B is responsible for adding the `StreamGeometry` icon resources (it needs the most). Phases C and D reference those keys without redefining.
+
+Final pass: run the app, eyeball against the mock, note remaining gaps.

+# Stream Formatter Rewrite — 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:** Rewrite `StreamLineFormatter` so Claude CLI stream-json messages (system/init, assistant text, assistant tool_use, user tool_result, result) render as compact readable lines in the Details pane.
+
+**Architecture:** Single-file rewrite of `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs`. Public API (`FormatLine(string)` / `FormatFile(string)` / `Trim`) and constants unchanged. Internal dispatch switches on top-level `type`; per-type helpers return one or more `\n`-terminated display lines, concatenated into the return string.
+
+**Tech Stack:** C# 12, .NET 8, `System.Text.Json` (already in use).
+
+**Spec:** `docs/superpowers/specs/2026-04-21-stream-formatter-rewrite-design.md`
+
+**Testing:** Skipped per user decision; verification is a manual build after each task and a final end-to-end run of a real task.
+
+**Build command (repo uses csproj builds, not slnx, on .NET 8):**
+```bash
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+```
+
+---
+
+## File Structure
+
+- **Modify:** `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs` — complete rewrite of parsing logic; keeps public class surface.
+
+No other files change. `DetailsIslandViewModel` and the Worker pipeline are unaffected.
+
+---
+
+## Task 1: Replace the dispatch skeleton
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs`
+
+Swap the old top-level `switch` for one that names every supported message type. Every branch returns `null` for now except `result` and `api_retry`, which keep their existing behavior. This gives us a clean compile before we fill in each branch.
+
+- [ ] **Step 1: Overwrite the file with the new skeleton**
+
+Replace the entire contents of `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs` with:

+## Task 6: Manual end-to-end verification
+
+**Files:** none (verification only).
+
+- [ ] **Step 1: Build everything the app needs**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj` and `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: both succeed, 0 errors.
+
+- [ ] **Step 2: Start the Worker in one terminal**
+
+Run: `dotnet run --project src/ClaudeDo.Worker`
+Expected: SignalR hub bound to `127.0.0.1:47821`, no crash.
+
+- [ ] **Step 3: Start the App in another terminal**
+
+Run: `dotnet run --project src/ClaudeDo.App`
+Expected: UI opens, status bar shows online.
+
+- [ ] **Step 4: Run any task tagged "agent" (e.g. "create a README")**
+
+In the Details pane, verify the log shows:
+- A `[session <id>…]` line at the top
+- Plain prose lines for assistant text
+- `[Read] <file>`, `[Bash] $ …`, `[Write] <file>` etc. for tool calls
+- `→ <N> lines` / `→ ok` / `→ error: …` lines after each tool call
+- A final `--- Result ---` block
+- **No raw JSON anywhere**
+
+- [ ] **Step 5: Spot-check the raw log file**
+
+Open `~/.todo-app/logs/<task>.log` (or equivalent) and confirm the full JSON is still there for debugging — the formatter must not have altered persisted logs.
+
+- [ ] **Step 6: If any issues surface, fix inline and re-verify**
+
+Common gotchas to check for if you see blank lines or missing output:
+- `message.content` sometimes absent → already guarded by `TryGetContentArray`
+- Unknown tool name → should render `[<name>]` with no arg
+- `tool_result.content` array form → covered by `ResolveContentText`
+
+No further commit unless a fix was needed.
+
+---
+
+## Post-Implementation Self-Review
+
+After the tasks above are done, verify:
+
+1. Every message type listed in the spec's "Output format" table is implemented (`system/init`, `system/api_retry`, `system/other`, `assistant text`, `assistant tool_use`, `assistant thinking`, `user tool_result`, `result`, parse failure).
+2. No `TODO` / `TBD` / commented-out stubs remain in `StreamLineFormatter.cs`.
+3. Tool labels match the spec table exactly (`[Read]`, `[Bash] $ …`, `[Task: <sub>] <desc>`, etc.).
+4. Public API surface (`FormatLine`, `FormatFile`, `Trim`, `MaxLength` behavior) is unchanged.
+5. No edits outside `StreamLineFormatter.cs` (per the spec's non-goals).

+# EF Core Migration Design
+
+Replace the raw ADO.NET / Microsoft.Data.Sqlite data layer with Entity Framework Core and LINQ queries.
+
+## Motivation
+
+- Developer ergonomics: raw SQL is tedious to write and maintain; LINQ enables faster iteration.
+- Maintainability: the ad-hoc migration approach (ALTER TABLE with error-code catching) and manual DBNull/enum mapping are a liability as the schema grows. EF Core provides proper migration versioning, value converters, and change tracking.
+
+## Decision Summary
+
+| Decision | Choice |
+|---|---|
+| Approach | Big bang — rewrite all 6 repositories at once |
+| Migration strategy | Fresh start — EF Core owns the schema, drop schema.sql |
+| DbContext sharing | Single shared `ClaudeDoDbContext` in ClaudeDo.Data |
+| Configuration style | Fluent API only, clean POCO models |
+| Atomic queue claim | Kept as `FromSqlRaw` — not expressible in LINQ |
+
+---
+
+## 1. DbContext and Entity Configuration
+
+### ClaudeDoDbContext
+
+A single `ClaudeDoDbContext` in `ClaudeDo.Data` with DbSets for all entities:
+
+```csharp
+public class ClaudeDoDbContext : DbContext
+{
+    public DbSet<TaskEntity> Tasks => Set<TaskEntity>();
+    public DbSet<ListEntity> Lists => Set<ListEntity>();
+    public DbSet<TagEntity> Tags => Set<TagEntity>();
+    public DbSet<ListConfigEntity> ListConfigs => Set<ListConfigEntity>();
+    public DbSet<WorktreeEntity> Worktrees => Set<WorktreeEntity>();
+    public DbSet<TaskRunEntity> TaskRuns => Set<TaskRunEntity>();
+    public DbSet<SubtaskEntity> Subtasks => Set<SubtaskEntity>();
+}
+```
+
+### Entity-to-Table Mapping
+
+| Entity | Table | Key | Notes |
+|---|---|---|---|
+| `TaskEntity` | `tasks` | `Id` (TEXT) | Nav to List, Tags, Worktree, Runs, Subtasks |
+| `ListEntity` | `lists` | `Id` (TEXT) | Nav to Tasks, Tags, Config |
+| `TagEntity` | `tags` | `Id` (INTEGER auto) | Nav to Lists, Tasks (both M:N) |
+| `ListConfigEntity` | `list_config` | `ListId` (TEXT) | 1:1 owned by List |
+| `WorktreeEntity` | `worktrees` | `TaskId` (TEXT) | 1:1 owned by Task |
+| `TaskRunEntity` | `task_runs` | `Id` (TEXT) | FK to Task |
+| `SubtaskEntity` | `subtasks` | `Id` (TEXT) | FK to Task |
+
+### Navigation Properties Added to Models
+
+```csharp
+// TaskEntity gains:
+public ListEntity List { get; set; }
+public WorktreeEntity? Worktree { get; set; }
+public ICollection<TagEntity> Tags { get; set; }
+public ICollection<TaskRunEntity> Runs { get; set; }
+public ICollection<SubtaskEntity> Subtasks { get; set; }
+
+// ListEntity gains:
+public ListConfigEntity? Config { get; set; }
+public ICollection<TaskEntity> Tasks { get; set; }
+public ICollection<TagEntity> Tags { get; set; }
+
+// TagEntity gains:
+public ICollection<ListEntity> Lists { get; set; }
+public ICollection<TaskEntity> Tasks { get; set; }
+```
+
+### Enum Handling
+
+EF Core `ValueConverter<TEnum, string>` for `TaskStatus` and `WorktreeState`, storing the same lowercase strings (`"manual"`, `"active"`, etc.) for database compatibility. The `ToDb`/`FromDb` methods in repositories are removed.
+
+### Junction Tables
+
+`list_tags` and `task_tags` are configured as implicit join tables via `.UsingEntity()` in Fluent API — no explicit junction entity classes needed.
+
+### Fluent Configuration
+
+Each entity gets its own `IEntityTypeConfiguration<T>` class in a `Configuration/` folder within `ClaudeDo.Data`.
+
+---
+
+## 2. Migration Strategy
+
+### Fresh Start
+
+- `schema.sql` and `SchemaInitializer` are deleted.
+- An initial EF Core migration (`InitialCreate`) is generated from the DbContext model, producing the full schema (all 8 tables, indexes, foreign keys, check constraints).
+- EF's `__EFMigrationsHistory` table tracks applied migrations.
+
+### Startup
+
+Both App and Worker call `context.Database.Migrate()` at startup instead of `SchemaInitializer.Apply()`. This is idempotent.
+
+### Existing Database Compatibility
+
+For users who already have a database created by `schema.sql`, the initial migration must handle the schema already existing. On startup, if the `lists` table exists but `__EFMigrationsHistory` does not, insert the initial migration record into `__EFMigrationsHistory` so EF skips it.
+
+### Seed Data
+
+The `"agent"` and `"manual"` tags move into `OnModelCreating` via `HasData()`:
+
+```csharp
+modelBuilder.Entity<TagEntity>().HasData(
+    new TagEntity { Id = 1, Name = "agent" },
+    new TagEntity { Id = 2, Name = "manual" });
+```
+
+### Ad-hoc Migrations Removed
+
+The 3 manual `ALTER TABLE` statements (model, system_prompt, agent_path on tasks) become part of the initial migration since they're already in the model. The manual `ApplyMigrations()` method is deleted.
+
+---
+
+## 3. Repository Rewrite
+
+All 6 repositories are rewritten to use `ClaudeDoDbContext` and LINQ.
+
+### Per-Repository Changes
+
+| Repository | After EF Core |
+|---|---|
+| `TagRepository` | LINQ queries. `GetOrCreateAsync` uses `FirstOrDefaultAsync` + `Add` + `SaveChangesAsync`. Static `SqliteConnection` overload removed. |
+| `SubtaskRepository` | Straightforward LINQ CRUD, `.OrderBy(s => s.OrderNum)`. |
+| `WorktreeRepository` | LINQ CRUD. State update becomes property set + `SaveChangesAsync`. |
+| `ListRepository` | LINQ CRUD. Tag management via `.Tags` navigation property. Config upsert via `List.Config` navigation. |
+| `TaskRunRepository` | LINQ CRUD. Latest = `.OrderByDescending(r => r.RunNumber).FirstOrDefaultAsync()`. |
+| `TaskRepository` | See special cases below. |
+
+### TaskRepository Special Cases
+
+**Atomic queue claim** (`GetNextQueuedAgentTaskAsync`): kept as `FromSqlRaw` / `ExecuteSqlRawAsync`. The `UPDATE ... WHERE id = (SELECT ...) RETURNING` is not expressible in LINQ and the atomicity guarantee matters.
+
+**Effective tags** (`GetEffectiveTagsAsync`): LINQ via navigation properties:
+
+```csharp
+var taskTags = context.Tasks
+    .Where(t => t.Id == taskId)
+    .SelectMany(t => t.Tags);
+var listTags = context.Tasks
+    .Where(t => t.Id == taskId)
+    .SelectMany(t => t.List.Tags);
+return await taskTags.Union(listTags).Distinct().ToListAsync(ct);
+```
+
+**FlipAllRunningToFailed**: EF Core 7+ bulk update:
+
+```csharp
+await context.Tasks
+    .Where(t => t.Status == TaskStatus.Running)
+    .ExecuteUpdateAsync(s => s.SetProperty(t => t.Status, TaskStatus.Failed), ct);
+```
+
+**Status transitions** (`MarkRunningAsync`, `MarkDoneAsync`, `MarkFailedAsync`): property updates + `SaveChangesAsync`.
+
+### Removed Code
+
+- `SqliteConnectionFactory.cs`
+- `SchemaInitializer.cs`
+- `schema/schema.sql`
+- All `ToDb`/`FromDb` enum mapping methods
+- All manual `DBNull.Value` handling
+- `BindTask` helper methods
+
+---
+
+## 4. Package Changes and DI Registration
+
+### ClaudeDo.Data.csproj
+
+- Remove: `Microsoft.Data.Sqlite`
+- Remove: embedded resource for `schema.sql`
+- Add: `Microsoft.EntityFrameworkCore.Sqlite`
+- Add: `Microsoft.EntityFrameworkCore.Design` (`PrivateAssets="all"`)
+
+### ClaudeDo.Worker.Tests.csproj
+
+- Remove: `Microsoft.Data.Sqlite`
+- Add: `Microsoft.EntityFrameworkCore.Sqlite`
+
+### App DI (Program.cs)
+
+```csharp
+// Replace SqliteConnectionFactory + singleton repos with:
+sc.AddDbContextFactory<ClaudeDoDbContext>(opt =>
+    opt.UseSqlite($"Data Source={dbPath}"));
+sc.AddScoped<ClaudeDoDbContext>(sp =>
+    sp.GetRequiredService<IDbContextFactory<ClaudeDoDbContext>>().CreateDbContext());
+sc.AddScoped<ListRepository>();
+sc.AddScoped<TaskRepository>();
+sc.AddScoped<SubtaskRepository>();
+sc.AddScoped<TagRepository>();
+sc.AddScoped<WorktreeRepository>();
+sc.AddScoped<TaskRunRepository>();
+
+// Migrate at startup:
+using var initScope = services.CreateScope();
+initScope.ServiceProvider.GetRequiredService<ClaudeDoDbContext>().Database.Migrate();
+```
+
+ViewModels are singletons that currently take repositories as constructor parameters. Since repositories become scoped, ViewModels switch to taking `IDbContextFactory<ClaudeDoDbContext>` and create a fresh context (+ repositories) per operation. Each ViewModel method that touches data does: `using var context = _factory.CreateDbContext();` then constructs or resolves the needed repository with that context. This mirrors the current connection-per-call pattern.
+
+### Worker DI (Program.cs)
+
+```csharp
+builder.Services.AddDbContext<ClaudeDoDbContext>(opt =>
+    opt.UseSqlite($"Data Source={cfg.DbPath}"));
+builder.Services.AddScoped<ListRepository>();
+builder.Services.AddScoped<TaskRepository>();
+builder.Services.AddScoped<SubtaskRepository>();
+builder.Services.AddScoped<TagRepository>();
+builder.Services.AddScoped<WorktreeRepository>();
+builder.Services.AddScoped<TaskRunRepository>();
+
+// Migrate at startup after build:
+using var scope = app.Services.CreateScope();
+scope.ServiceProvider.GetRequiredService<ClaudeDoDbContext>().Database.Migrate();
+```
+
+Worker has request scopes via SignalR hub invocations, so scoped registration works naturally.
+
+---
+
+## 5. Test Infrastructure
+
+### DbFixture
+
+`DbFixture` is rewritten as an EF Core fixture:
+
+- Creates a temp SQLite file per test class.
+- Builds `DbContextOptions<ClaudeDoDbContext>` with `UseSqlite`.
+- Calls `context.Database.Migrate()` to apply the schema (also tests that migrations work).
+- Exposes a `CreateContext()` method so each test gets a fresh context instance (avoids change-tracker bleed).
+
+Tests construct repositories by passing in a fresh context from the fixture.
+
+No mocking — tests keep hitting real SQLite, same philosophy as today.
+
+---
+
+## 6. Risk and Mitigation
+
+| Risk | Mitigation |
+|---|---|
+| Big-bang rewrite touches nearly every file in ClaudeDo.Data | Existing tests are the safety net — all must pass after migration |
+| Existing databases with schema from schema.sql | Compatibility shim: detect existing tables, mark initial migration as applied |
+| Atomic queue claim semantics change | Kept as raw SQL via `FromSqlRaw` |
+| Scoped lifetime vs. singleton ViewModels | `IDbContextFactory` provides on-demand contexts |
+| EF change tracker overhead vs. raw ADO.NET | Negligible for this workload size; use `AsNoTracking()` for read-only queries |

+# Subtask Tree View in Task List
+
+## Problem
+
+Subtasks are invisible in the task list — users only see them after opening the detail pane or editor modal. This makes it hard to get an overview of task progress without clicking into each task individually.
+
+## Solution
+
+Show subtasks indented below their parent task in the task list, with expand/collapse. Tasks start collapsed with a visual indicator when subtasks exist.
+
+## Scope
+
+Pure UI/ViewModel change. No data model changes, no new migrations, no repository schema changes.
+
+## Design
+
+### ViewModel Changes
+
+**TaskItemViewModel** — add:
+
+- `ObservableCollection<SubtaskItemViewModel> Subtasks` — populated on first expand
+- `bool IsExpanded` — observable, default `false`; toggles subtask visibility
+- `bool HasSubtasks` — observable, set during initial load from a count query
+- `int SubtaskCount` — observable, used for the indicator
+- `ToggleExpandedCommand` — flips `IsExpanded`; on first expand, loads subtasks from `SubtaskRepository.GetByTaskIdAsync`
+- `ToggleSubtaskDoneCommand(string subtaskId)` — toggles a subtask's `Completed` and persists via `SubtaskRepository.UpdateAsync`
+
+Constructor gains `SubtaskRepository` and initial `subtaskCount` parameter.
+
+**TaskListViewModel.LoadAsync** — after fetching tasks, run a single batch query to get subtask counts per task. Pass counts into each `TaskItemViewModel`. This avoids N+1 queries on load.
+
+**TaskListViewModel.RefreshSingleAsync** — if the refreshed task's `IsExpanded` is true, also reload its subtasks from DB and update the collection.
+
+### Repository Changes
+
+**SubtaskRepository** — add one method:
+
+```csharp
+Task<Dictionary<string, int>> GetCountsByTaskIdsAsync(IEnumerable<string> taskIds, CancellationToken ct = default)
+```
+
+Single query: `SELECT task_id, COUNT(*) FROM subtasks WHERE task_id IN (...) GROUP BY task_id`. Returns a map of taskId -> count. Tasks with no subtasks won't appear in the result (count defaults to 0).
+
+### XAML Changes
+
+**TaskListView.axaml** — the `DataTemplate` for `TaskItemViewModel` becomes a 2-row grid:
+
+```
+Row 0: [ExpandChevron] [StatusCircle] [Title + Tags/Status subtitle]
+Row 1: [SubtaskItemsControl, margin-left ~40px, visible when IsExpanded]
+```
+
+**Row 0 — Expand chevron:**
+- Column 0 gets a small chevron button (12x12 `Path` data) before the status circle
+- Right-pointing when collapsed, down-pointing when expanded
+- Bound to `ToggleExpandedCommand`
+- Only visible when `HasSubtasks` is true (via `IsVisible` binding)
+- When `HasSubtasks` is false, the space is empty but reserved (fixed-width column) so all titles align
+
+**Row 1 — Subtask list:**
+- `ItemsControl` bound to `Subtasks`
+- `IsVisible` bound to `IsExpanded`
+- Left margin ~40px for visual indentation
+- Each subtask item: `CheckBox` (bound to `Completed`) + `TextBlock` (bound to `Title`)
+- Subtask row has its own context menu flyout with "Edit Task" (opens parent task's editor modal via `EditTaskCommand` on root `TaskListViewModel`)
+- Checkbox toggle calls `ToggleSubtaskDoneCommand` on the parent `TaskItemViewModel`
+
+**Column layout change:** The existing 2-column `Grid` (`Auto, *`) gets a third column prepended: `Auto, Auto, *`. The chevron goes in column 0, status circle in column 1, title stack in column 2. Row 1 spans all 3 columns.
+
+### Subtask Checkbox Interaction
+
+When a subtask checkbox is toggled in the list:
+1. Update the `SubtaskItemViewModel.Completed` property
+2. Call `SubtaskRepository.UpdateAsync` with the updated entity (same auto-save pattern as `TaskDetailView`)
+3. No need to refresh the parent task — subtask completion doesn't affect task status
+
+### Subtask Context Menu
+
+Right-click on a subtask row shows:
+- "Edit Task" — opens the parent task's editor modal (same flow as `EditTaskCommand`)
+
+This reuses the existing editor which already has full subtask editing (add/remove/reorder/rename).
+
+### Real-time Updates
+
+When `RefreshSingleAsync` fires (via SignalR `TaskUpdatedEvent`):
+1. Reload subtask count, update `HasSubtasks` and `SubtaskCount`
+2. If `IsExpanded`, reload subtask list from DB and reconcile with the observable collection
+
+### Detail Pane Sync
+
+When the user edits subtasks in `TaskDetailView` (auto-save) or `TaskEditorView` (batch-save), the list view's subtask state may become stale. Two options:
+
+**Chosen approach:** The detail pane and editor already trigger `TaskUpdatedEvent` (or the editor's save path calls `RefreshSingleAsync` via `SelectedTask.Refresh`). Extend `Refresh` on `TaskItemViewModel` to also reload subtasks if expanded, and update `HasSubtasks`/`SubtaskCount`.
+
+### Visual Style
+
+- Chevron: 10x10 path, `TextDimBrush` color, no background, cursor=Hand
+- Subtask rows: smaller font (12px), `TextDimBrush` for unchecked title, strikethrough + dimmed for completed
+- Subtask checkbox: standard Avalonia `CheckBox` (no custom circular border), small size
+- Subtask row vertical padding: 2px (compact)
+- Indent: 40px left margin on the subtask `ItemsControl`
+
+## Files to Modify
+
+1. `src/ClaudeDo.Data/Repositories/SubtaskRepository.cs` — add `GetCountsByTaskIdsAsync`
+2. `src/ClaudeDo.Ui/ViewModels/TaskItemViewModel.cs` — add subtask collection, expand/collapse, toggle done
+3. `src/ClaudeDo.Ui/ViewModels/TaskListViewModel.cs` — batch-load counts, pass SubtaskRepository, extend refresh
+4. `src/ClaudeDo.Ui/Views/TaskListView.axaml` — restructure item template with chevron + nested ItemsControl
+5. `src/ClaudeDo.Ui/Views/TaskListView.axaml.cs` — handle subtask context menu pointer-pressed if needed
+6. `src/ClaudeDo.App/Program.cs` — pass SubtaskRepository to TaskListViewModel (if not already available via DI)
+
+## Out of Scope
+
+- Drag-to-reorder subtasks in the list view
+- Add subtask directly from the list view
+- Subtask progress indicator (e.g., "2/5 done") on collapsed tasks
+- Recursive task nesting (tasks containing tasks)

+# Settings Modal — Design
+
+**Date:** 2026-04-21
+**Status:** Approved for planning
+
+## Goal
+
+Add a general-settings modal reachable from the **⋯** button in the user footer of the Lists island (`ListsIslandView.axaml:68`). The modal exposes app-wide defaults for Claude runs, worktree behavior, and maintenance actions (cleanup / force-remove worktrees), plus a read-only "About" section with paths.
+
+## Scope
+
+**In scope**
+
+- Claude defaults: instructions, model, max turns, permission mode
+- Worktree defaults: strategy, central root, auto-cleanup toggle + days
+- Worktree maintenance actions: cleanup finished, force-remove all
+- About section: version, data/logs/config paths with "Open in Explorer"
+- Single settings row persisted in SQLite
+- SignalR surface for read/update + maintenance
+- `ClaudeArgsBuilder` merge behavior for per-task overrides
+
+**Out of scope**
+
+- Worker-side infrastructure settings (hub URL, auto-start worker) — stays in `worker.config.json`
+- Per-task "inherit defaults" toggle (always inherit; task values override per rule below)
+- Any UI-layer tests (project has none today)
+
+## Architecture
+
+### Persistence
+
+New single-row entity `AppSettingsEntity` (Id = 1) in SQLite. Access via new `AppSettingsRepository` with `GetAsync` / `UpdateAsync`. Seeded by a new EF migration `AddAppSettings`.
+
+Fields:
+
+| Column | Type | Seed default |
+|---|---|---|
+| `DefaultClaudeInstructions` | text | `""` |
+| `DefaultModel` | string | `sonnet` |
+| `DefaultMaxTurns` | int | `30` |
+| `DefaultPermissionMode` | string | `acceptEdits` |
+| `WorktreeStrategy` | string | `sibling` |
+| `CentralWorktreeRoot` | string? | `null` |
+| `WorktreeAutoCleanupEnabled` | bool | `false` |
+| `WorktreeAutoCleanupDays` | int | `7` |
+
+Rationale for DB over `worker.config.json`: transactional writes from the UI, no file-watcher dance, and the Worker already uses `IDbContextFactory<ClaudeDoDbContext>`.
+
+### Merge rules for per-task overrides
+
+`ClaudeArgsBuilder` gains a dependency on `AppSettingsRepository` and merges at build time:
+
+- **Instructions:** `global + "\n\n" + task` (skip separator if either side empty)
+- **Model / MaxTurns / PermissionMode:** `task ?? global` (task value wins when set)
+
+No `TaskEntity` schema change.
+
+### SignalR surface (new hub methods)
+
+| Method | Returns | Notes |
+|---|---|---|
+| `GetAppSettings()` | `AppSettingsDto` | Single row |
+| `UpdateAppSettings(dto)` | void | Full-row replace |
+| `CleanupFinishedWorktrees()` | `int removedCount` | Skips Active |
+| `ResetAllWorktrees()` | `{ removed, tasksAffected }` | Fails if any task is Running |
+
+Maintenance logic lives in a new `WorktreeMaintenanceService` in the Worker; the hub stays thin. Service uses existing `GitService` + `WorktreeRepository`.
+
+**Running-task guard:** `ResetAllWorktrees()` checks for any `Running` tasks before touching anything. If present, returns an error — the modal surfaces *"Cannot force-remove: N task(s) still running. Cancel them first."*
+
+Affected worktrees after force-remove are marked `Discarded` in `WorktreeRepository`.
+
+## UI
+
+### Entry point
+
+`ListsIslandView.axaml:68` ⋯ button binds to a new `OpenSettingsCommand` on `IslandsShellViewModel`. Command resolves `SettingsModalViewModel` and shows `SettingsModalView` via the existing modal pattern (`TaskCompletionSource<bool>` on save/cancel — same as `WorktreeModalView` / `DiffModalView`).
+
+### Layout
+
+Single scrollable modal, ~560 px wide, matches existing modal chrome (header eyebrow, monospace labels, close affordance). No tabs.
+
+**Sections (top to bottom):**
+
+1. **CLAUDE DEFAULTS** — instructions textarea (6 lines), model picker, max-turns numeric, permission-mode picker
+2. **WORKTREES** — strategy picker, central-root folder picker, auto-cleanup toggle + days, then the two maintenance buttons
+3. **ABOUT** — version (read-only), data folder / logs folder / worker.config path, each with "Open in Explorer" icon button
+
+Footer: `[ Cancel ]` `[ Save ]`, right-aligned. Save button disabled while the form is invalid.
+
+### Destructive action UX
+
+- **Cleanup finished** — single click, inline result line under the button (`"Removed 3 worktree(s)."`), auto-clears ~4 s
+- **Force-remove all** — click reveals an inline confirm row: *"Remove ALL N worktrees? Uncommitted work will be lost."* with red `Remove All` and neutral `Cancel`. Two-click confirm, no typed string (matches the delete-task confirm already in the app)
+
+Both run against the worker over SignalR and leave the modal open on completion.
+
+### Open-in-Explorer
+
+Uses `Process.Start("explorer.exe", path)`. Windows-only is acceptable (app ships Windows-only via WPF installer).
+
+### Validation
+
+Modal-side only, block `Save`:
+
+- Max turns: integer 1–200
+- Auto-cleanup days: integer 1–365 (required only when toggle is on)
+- Central root: required when Strategy = Central; must be an existing directory
+- Instructions: no length cap
+
+Invalid fields get a red eyebrow with the specific error text.
+
+## Testing (ClaudeDo.Worker.Tests)
+
+- **`AppSettingsRepositoryTests`** — round-trip `Get` / `Update` on real SQLite
+- **`ClaudeArgsBuilderTests`** — four merge cases: both empty, only global, only task, both set (prepend + separator behavior)
+- **`WorktreeMaintenanceServiceTests`** — real git worktree fixtures:
+  - cleanup skips `Active`, removes `Merged` / `Discarded` / `Kept`
+  - force-remove fails while any task is `Running`
+  - force-remove succeeds otherwise and flips affected worktrees to `Discarded`
+
+No UI-layer tests (project has none today).
+
+## Build order (high level)
+
+1. Data: entity + configuration + migration + repository
+2. Worker: `WorktreeMaintenanceService` + `ClaudeArgsBuilder` wiring + hub methods + DTO
+3. UI: SignalR client methods on `WorkerClient`, `SettingsModalViewModel`, `SettingsModalView`
+4. Wire ⋯ button on `ListsIslandView` → `IslandsShellViewModel.OpenSettingsCommand`
+5. Tests (Worker.Tests)
+
+Detailed step-by-step sequencing belongs in the implementation plan, not here.

+# Stream Formatter Rewrite — Design
+
+**Date:** 2026-04-21
+**Scope:** `src/ClaudeDo.Ui/Helpers/StreamLineFormatter.cs`
+
+## Problem
+
+`StreamLineFormatter` converts Claude CLI stream-json lines into human-readable
+text for the Details pane. The current implementation only recognizes:
+
+- `type=stream_event` — dead code (requires `--include-partial-messages`, which
+  the Worker does not pass)
+- `type=result` — shown as `--- Result ---` block
+- `type=system` with `subtype=api_retry`
+
+Everything else — notably `assistant` and `user` messages that carry the actual
+conversation and tool activity — falls through to `default: return null` and is
+silently dropped. The Details pane is therefore mostly empty during a run,
+while the raw `.log` file retains the full JSON.
+
+## Goal
+
+Rewrite the formatter so every meaningful message type is rendered as one or
+more compact text lines suitable for the live log in the Details pane. The
+public API (`FormatLine(string)` / `FormatFile(string)`) and the existing
+buffer/trim behavior in `DetailsIslandViewModel` stay the same.
+
+## Input format
+
+The Worker invokes the Claude CLI with:
+
+```
+claude -p --output-format stream-json --verbose --dangerously-skip-permissions ...
+```
+
+Each stdout line is one complete SDK message. Top-level shapes relevant to the
+formatter:
+
+```jsonc
+// Session start
+{"type":"system","subtype":"init","session_id":"…","model":"claude-…", …}
+
+// API retry notification
+{"type":"system","subtype":"api_retry", …}
+
+// Assistant reply (text + tool calls)
+{"type":"assistant","message":{"role":"assistant","content":[
+  {"type":"text","text":"…"},
+  {"type":"tool_use","id":"toolu_…","name":"Read","input":{"file_path":"…"}}
+]}, …}
+
+// Tool result fed back to the model
+{"type":"user","message":{"role":"user","content":[
+  {"tool_use_id":"toolu_…","type":"tool_result","content":"… or [ {type,text} ] …","is_error":false}
+]}, "tool_use_result":{…optional rich payload…}, …}
+
+// Final result
+{"type":"result","result":"…", …}
+```
+
+Notes on quirks already observed in captured output:
+
+- `tool_result.content` is sometimes a plain string, sometimes an array of
+  `{type:"text", text:"…"}` blocks. Handle both.
+- The envelope may include `tool_use_result.file.numLines` / `file.filePath`
+  for Read-style results.
+- Assistant messages may contain `thinking` blocks (filtered, not displayed).
+
+## Output format
+
+One line per logical event. A trailing `\n` ends each line so the
+`DetailsIslandViewModel` buffer splits cleanly.
+
+| Input | Output |
+|---|---|
+| `system` / `init` | `[session <id8> · <model>]\n` |
+| `system` / `api_retry` | `[Retrying API call...]\n` |
+| `system` / other | `null` (filtered) |
+| `assistant` text block | `<text>\n` (raw) |
+| `assistant` tool_use block | `[<ToolLabel>] <arg>\n` (see below) |
+| `assistant` thinking block | `null` (filtered) |
+| `user` tool_result block | `→ <summary>\n` (see below) |
+| `result` | `\n--- Result ---\n<text>\n` |
+| unrecognized / parse failure | raw line (existing behavior for non-JSON) |
+
+A single `assistant` message with N content blocks produces N output lines,
+concatenated into one return string.
+
+### Tool label + arg
+
+Pick the most identifying input field per tool:
+
+| Tool name | Display |
+|---|---|
+| `Read`, `Write`, `Edit`, `NotebookEdit` | `[<Tool>] <basename(file_path)>` |
+| `Bash`, `PowerShell` | `[Bash] $ <command>` — truncate command at 120 chars, append `…` |
+| `Grep` | `[Grep] "<pattern>"` |
+| `Glob` | `[Glob] <pattern>` |
+| `Task`, `Agent` | `[Task: <subagent_type>] <description>` (description truncated to 120) |
+| `WebFetch` | `[WebFetch] <url>` |
+| `WebSearch` | `[WebSearch] "<query>"` |
+| `TodoWrite` | `[TodoWrite]` (no arg) |
+| fallback | `[<name>]` |
+
+Missing or empty input fields → emit the label only, no trailing text.
+
+### tool_result summary
+
+For each `tool_result` block in a `user` message, in priority order:
+
+1. `is_error == true` → `→ error: <first non-empty line, trimmed, ≤120 chars>`
+2. Envelope has `tool_use_result.file.numLines` → `→ <N> lines`
+3. Content resolves to empty/whitespace string → `→ ok`
+4. Otherwise → `→ <first non-empty line, ≤120 chars>` (append `…` if truncated)
+
+Content resolution: if `content` is a string, use it; if it's an array, join
+the `text` fields of `{type:"text"}` entries.
+
+## Non-goals
+
+- No changes to `DetailsIslandViewModel` or the Worker pipeline.
+- No collapsible/rich rendering — tool results stay one-liners.
+- No persistence changes — the raw `.log` file still contains full JSON for
+  debugging.
+- No unit tests in this change (separate workload).
+
+## Out of scope
+
+- Partial-token streaming (`--include-partial-messages`). The existing
+  `stream_event` branch is removed as dead code.
+- Structured output / `--json-schema` rendering beyond the final `result`.
+
+## Risks / edge cases
+
+- **Unknown tool names** — fallback label `[<name>]` keeps output readable.
+- **Malformed JSON inside a valid envelope** (e.g. missing `message.content`)
+  — skip the broken block, emit what we can; never throw.
+- **Very long Bash commands or search queries** — 120-char truncation with `…`
+  keeps lines reasonable while preserving the prefix.
+- **Binary or huge tool_result content** — summary rules 2–4 cap output at a
+  single line; full content stays in the raw log.
