feat(settings): default permission mode to auto and surface it in UI

Replaces "bypassPermissions" with "auto" as the default for new installs
and adds "auto" as the first option in the settings dropdown. Existing
rows keep their stored value; ClaudeArgsBuilder still maps the legacy
"bypassPermissions" -> "auto" at dispatch time.

+# Task Mailbox — Push Messages Into Running Sessions
+
+**Status:** proposal
+**Context:** the user runs parallel Claude sessions (e.g. backend + frontend) and wants to push messages into a session while it's busy inside a subagent. A shared folder works for one-offs; this turns it into a first-class ClaudeDo feature so every future parallel-session project gets it for free.
+
+## Problem
+
+Claude CLI processes one turn at a time. While a subagent (or any long tool) runs, no new user input can be injected. The harness offers no mid-execution interrupt. The workable window is *between* tool calls — so we need a cheap "inbox check" the agent can poll at natural checkpoints, plus a UI affordance and a cross-session sender.
+
+## Design
+
+### 1. Data
+
+New table `task_messages`:
+
+| col | type | notes |
+|---|---|---|
+| `id` | INTEGER PK | |
+| `task_id` | TEXT FK → tasks.id | recipient |
+| `sender` | TEXT | `'user'` \| `'task:<id>'` (for cross-session) |
+| `body` | TEXT | markdown |
+| `created_at` | TEXT | ISO |
+| `delivered_at` | TEXT NULL | set when inbox pulls it |
+
+EF Core migration + repository. Async, CancellationToken, matches existing conventions.
+
+### 2. Worker MCP tools (extend existing `mcp__claudedo__*` server)
+
+- **`check_inbox(task_id)`** → returns undelivered messages for this task and marks them delivered. Idempotent. Empty array if nothing pending.
+- **`send_to_task(task_id, body)`** → inserts a row. Callable from *any* session — this is how the frontend session tells the backend session something.
+- **`inbox_status(task_id)`** → `{ pending: int }` for a cheap "is there anything?" poll.
+
+All three run in-proc in the Worker, go through the existing repository layer.
+
+### 3. SignalR additions on `WorkerHub`
+
+Server methods (UI → Worker):
+- `SendTaskMessage(taskId, body)` — UI calls this; worker inserts the row and fires `TaskMessageQueued`.
+
+Client events (Worker → UI):
+- `TaskMessageQueued(taskId, pendingCount)` — so the UI can show an unread badge.
+- `TaskMessageDelivered(taskId, pendingCount)` — when the agent pulls it, badge clears.
+
+### 4. UI
+
+On every `Running` task row + detail pane:
+- "Send to session" textarea + Enter to submit → `SendTaskMessage`.
+- Unread badge showing `pendingCount`.
+- Read-only message timeline (who sent what, when delivered).
+
+### 5. Agent-side poll discipline
+
+Two complementary mechanisms so it's robust whether or not the agent remembers:
+
+**a) CLAUDE.md instruction** (seeded by worker into each worktree's `CLAUDE.md`):
+> After every subagent completes and before starting the next step, call `mcp__claudedo__check_inbox`. Treat returned messages as user input with priority over the current plan.
+
+**b) PostToolUse hook on `Agent`** (written into the worktree's `.claude/settings.json` by the Worker when it creates the tree):
+- Runs `mcp__claudedo__inbox_status` via a tiny CLI shim the worker ships.
+- If `pending > 0`, the hook emits a system reminder: "Inbox has N pending messages — call `mcp__claudedo__check_inbox` now."
+- Keeps the burden off the agent's memory. Belt + suspenders.
+
+### 6. Cross-session pattern
+
+Backend session and frontend session are just two tasks with known IDs. Either can call `send_to_task(other_id, body)` via the MCP server. No shared folder needed — the DB is already the shared channel.
+
+To make this ergonomic:
+- A "linked tasks" concept: tag two tasks as peers at creation time. The Worker exposes `send_to_peer(body)` as sugar around `send_to_task` so neither session needs to hardcode the other's UUID.
+
+## Limits (honest)
+
+- Messages arrive *between* tool calls, not mid-tool. A 20-minute subagent still blocks 20 minutes. Splitting work into shorter subagents is still the right discipline.
+- If the agent ignores the CLAUDE.md instruction, the hook catches it next tool call — but we can't force immediate consumption.
+- `-p` (print) mode with stdin prompt is one-shot and can't be extended. This design targets *interactive* sessions (Planning Sessions already use this mode). For queued `-p` runs, the mailbox is effectively a post-run instruction carrier.
+
+## Why this is the repeatable "Grundgerüst"
+
+Once this lands in ClaudeDo, the workflow becomes:
+1. Create two linked tasks (`backend`, `frontend`) with `working_dir` set.
+2. Start each — each gets its own worktree, its own Planning Session terminal, its own inbox with `check_inbox` + `send_to_peer`.
+3. Push messages from the UI or from the other session. No per-project scaffolding, no custom hooks, no shared folder.
+
+Every future parallel-session project inherits the mailbox.
+
+## Build order (suggested)
+
+1. Migration + repo + model. Tests first.
+2. MCP tools (`check_inbox`, `send_to_task`, `inbox_status`) + unit tests.
+3. SignalR method + events + UI textarea/badge.
+4. Worker writes CLAUDE.md addendum + `.claude/settings.json` hook into each new worktree.
+5. Linked-tasks sugar (`send_to_peer`).
+6. Manual verification: queue a long subagent, send a message, confirm it's picked up at the next tool boundary.
+
+## Open questions
+
+- Should messages be deleted or soft-kept after delivery? Leaning soft-kept for the timeline UI.
+- Priority / interrupt semantics — do we want a "high priority" flag that the agent should surface immediately vs. batch?
+- Should `send_to_peer` also work when the peer is `Queued` (i.e. not yet running)? Probably yes — deliver on start.

 9. **Tag-Negation (3.4)** — wenn der Bedarf konkret wird.
 
 Punkte 1–3 sind ein realistischer Block für eine Session.
+
+---
+
+## Self-Update — Manual Verification
+
+Preconditions: a working Gitea release at `git.kuns.dev/releases/ClaudeDo` with three assets — `ClaudeDo-<version>-win-x64.zip`, `ClaudeDo.Installer-<version>.exe`, and `checksums.txt` listing both.
+
+1. Install a baseline version (e.g. `0.2.x`) normally.
+2. Publish a new release tagged `v0.3.0` with fresh installer + app zip + checksums.
+3. Launch the app — confirm the banner appears: `Update available: v0.2.x → v0.3.0`.
+4. Click **Update now** — app closes, installer opens in Update mode, runs, restarts the worker.
+5. Re-launch the app — banner is gone; `Help → Check for updates` briefly shows "You're up to date (v0.3.0)".
+6. Run the `v0.2.x` installer manually — confirm it prompts to self-update to v0.3.0. Click **Update** → running exe is replaced and the wizard opens on the new version.
+7. Repeat step 6 with **Continue anyway** → wizard opens without self-update.
+8. Repeat step 6 with **Cancel** → installer exits without any action.
+9. Kill network during startup in both app and installer → confirm silent fallback (no errors, no banner, wizard opens normally).
+
+---
+
+## Planning Sessions — Manual Verification (Plan C UI)
+
+Requires Plan B (worker hub endpoints) merged. Until then, only the UI structure/styling checks are meaningful.
+
+1. Create a Manual task with a title and a TODO-ish description.
+2. Right-click the task → **Open planning Session** — Windows Terminal opens with Claude CLI running (Plan B).
+3. Ask Claude to create two child tasks via `mcp__claudedo__create_child_task`.
+4. Watch the UI: drafts appear indented under the parent, italic, reduced opacity, with a `DRAFT` badge.
+5. The parent shows a `PLANNING` badge. Click the chevron → children collapse; click again → children expand.
+6. Ask Claude to `finalize` — drafts flip to Manual/Queued children; parent flips to `PLANNED` badge.
+7. In a new planning task, close the terminal without finalize. Right-click the Planning task → the unfinished-session modal opens with Resume / Finalize now / Discard.
+8. Attempt to delete a parent with children via the details panel — confirm the friendly error dialog appears and the task is NOT deleted.
+
+**Known followups (non-blocking):**
+- `Border.badge.planned` style (blue) is defined in `IslandStyles.axaml` but never applied — `TaskRowView` keeps the `planning` class for both Planning and Planned, so Planned gets the amber badge. Either make the view swap `Classes.planned` when status is Planned, or remove the unused style + brush.
+- Dead `Instance` statics on `BoolToItalicConverter` and `BoolToDraftOpacityConverter` — App.axaml registers instances via the resource dictionary; the static members can be removed.

+# ClaudeDo — Prompt & CLI Inventory
+
+Snapshot of every string ClaudeDo sends to Claude CLI, plus the CLI-flag surface that shapes each run. Intended as a working doc for tomorrow's prompt-tuning pass.
+
+Date: 2026-04-24
+
+---
+
+## 1. Task-execution prompts (agent-tagged tasks → Claude CLI)
+
+Used for every "agent" task that the queue picks up or that `RunNow` dispatches.
+Orchestration lives in `src/ClaudeDo.Worker/Runner/TaskRunner.cs` and `ClaudeArgsBuilder.cs`.
+
+### 1.1 User prompt (stdin) — `TaskRunner.RunAsync` ~L101–L110
+
+Plain text, no template around it:
+
+```
+{task.Title}
+
+{task.Description?.Trim()}        ← only if non-empty
+
+## Sub-Tasks                      ← only if subtasks exist
+- [ ] {subtask.Title}             ← "[x]" if completed
+...
+```
+
+Notes
+- Title is included verbatim — no leading `#` heading.
+- No role tags, no XML, no delimiters between title and description — just blank lines.
+- Sub-Tasks section uses markdown checkboxes. This is the only structural scaffolding.
+- No context about the project, working dir, or git state is added here.
+
+### 1.2 Retry prompt (on failure, when a session ID exists) — `TaskRunner` ~L126
+
+```
+The previous attempt failed with:
+
+{result.ErrorMarkdown}
+
+Try again and fix the issues.
+```
+
+Fired once per task via `--resume <session_id>`; if the retry also fails, the task is marked Failed.
+
+### 1.3 Follow-up prompt (multi-turn `ContinueAsync`) — `TaskRunner.ContinueAsync` L159
+
+The UI/hub supplies `followUpPrompt` as-is; no wrapping. The session is resumed via `--resume`. So the effective "prompt template" is whatever the user types in the Continue textbox.
+
+### 1.4 System prompt — merged in `TaskRunner` ~L413–L418
+
+Built by `TaskRunner.MergeInstructions(global, list, task)` which concatenates three optional strings with `\n\n`:
+
+1. `AppSettings.DefaultClaudeInstructions` (global, set in Settings modal, default `""`)
+2. `list_config.SystemPrompt` (per-list override)
+3. `task.SystemPrompt` (per-task override)
+
+The merged string is passed as `--append-system-prompt <instructions>` to the CLI. Empty/whitespace → flag is omitted entirely.
+
+**Currently the global `DefaultClaudeInstructions` ships as empty string** (see `AppSettingsEntity.cs` L9). Anything in the system prompt today is whatever the user typed into Settings / List-Settings / Task-Settings.
+
+### 1.5 CLI args — `ClaudeArgsBuilder.Build` (`ClaudeArgsBuilder.cs`)
+
+Always on:
+- `-p`
+- `--output-format stream-json`
+- `--verbose`
+- `--permission-mode {auto|acceptEdits|plan|default}` (legacy `bypassPermissions` → `auto`)
+
+Conditional:
+- `--model {sonnet|opus|haiku|...}` — from `task.Model ?? list.Model ?? AppSettings.DefaultModel` (default `sonnet`)
+- `--max-turns {n}` — `AppSettings.DefaultMaxTurns` (default `100`)
+- `--append-system-prompt "{merged instructions}"` — see 1.4
+- `--agents '[{"file":"{path}"}]'` — from task or list override, points at an agent `.md`
+- `--resume {session_id}` — for retries and `ContinueAsync`
+
+Unused but pre-declared:
+- `ResultSchema` — a `{summary, files_changed, commit_type}` JSON schema is serialized but **never attached** to args in `Build`. Dead code today; relevant if we turn on `--output-schema`.
+
+---
+
+## 2. Planning-agent prompts (`/plan` / Planning session)
+
+Used by the Planning feature, which spawns a Claude session inside a git worktree with MCP tools so the agent can create Subtasks under the parent.
+Source: `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs`.
+
+### 2.1 System prompt — `BuildSystemPrompt()` L290–L308
+
+```
+You are a planning assistant for ClaudeDo.
+Your role is to help break down a task into smaller, actionable subtasks.
+Your final goal WILL ALWAYS be the creation of Subtasks
+
+ALWAYS invoke the `superpowers:brainstorming` skill via the Skill tool at the
+start of every planning session, and follow its process end-to-end. It guides
+you through clarifying questions, approach exploration, and design approval
+BEFORE any subtasks are created. Do not create child tasks until the user has
+approved a design.
+
+NEVER Change files yourself. 
+
+ALWAYS Use the available MCP tools (mcp__claudedo__*) to create child tasks once the
+design is approved. When you are done planning, finalize the session.
+
+Be concise and focused. Each subtask should be independently executable.
+```
+
+Written to `{session-dir}/system-prompt.md` at session start and fed via `--append-system-prompt`.
+
+Notes / known oddities
+- Trailing space on "NEVER Change files yourself. " and on the blank line above the ALWAYS/MCP block.
+- Mixes voice ("Your role is", "ALWAYS invoke") — could be tightened.
+- Implicitly relies on the `superpowers:brainstorming` skill being installed in the worktree's Claude config.
+- Does not name the MCP tools explicitly (the `mcp__claudedo__*` wildcard assumes the agent discovers them via tool listing).
+
+### 2.2 Initial prompt — `BuildInitialPrompt(task)` L310–L323
+
+```
+# Task: {task.Title}
+
+{task.Description}     ← only if non-empty
+
+---
+
+Please analyze this task and break it down into concrete subtasks.
+```
+
+Written to `{session-dir}/initial-prompt.txt`; the Windows Terminal launcher pipes it to the Claude CLI on start.
+
+### 2.3 Planning session CLI flags
+
+`PlanningSessionManager` itself does not build CLI args — the `WindowsTerminalPlanningLauncher` does. Relevant facts:
+- Permission mode: **plan** (per recent commit `8e9f09a` "run planning agent in plan permission mode and enforce brainstorming skill").
+- Runs with an `.mcp.json` that points at our local MCP server (`http://127.0.0.1:{port}/mcp`) with a per-session bearer token.
+- `.claude/settings.local.json` sets `"enableAllProjectMcpServers": true` so the MCP tools auto-activate.
+
+---
+
+## 3. Commit-message template (not a prompt, but agent-visible)
+
+Built by `CommitMessageBuilder.Build` (`CommitMessageBuilder.cs`). Format:
+
+```
+{commitType}({listSlug}): {title ≤60 chars}
+
+{description ≤400 chars}        ← only if set
+
+ClaudeDo-Task: {taskId}
+```
+
+- `commitType` comes from `task.CommitType` (default `chore`, list default configurable).
+- Slug = lowercased list name with non-alphanumerics stripped, runs collapsed to `-`.
+- The agent sees the resulting commit in `git log` during retries and follow-ups, so phrasing here bleeds into model behavior on multi-turn work.
+
+---
+
+## 4. Where each prompt is edited (UI surface)
+
+| Prompt slot                         | Edited in                                  | Stored as                                  |
+|-------------------------------------|--------------------------------------------|--------------------------------------------|
+| Global `DefaultClaudeInstructions`  | Settings modal (`SettingsModalViewModel`)  | `app_settings.DefaultClaudeInstructions`   |
+| Per-list system prompt              | List-Settings modal                        | `list_config.SystemPrompt`                 |
+| Per-task system prompt              | Details island / task agent settings       | `tasks.system_prompt`                      |
+| Per-task agent file                 | Details island                             | `tasks.agent_path` (absolute `.md` path)   |
+| Default model / max turns / perms   | Settings modal                             | `app_settings.*`                           |
+| Planning system prompt              | **Hard-coded** in `PlanningSessionManager` | not editable from UI                       |
+| Planning initial prompt template    | **Hard-coded** in `PlanningSessionManager` | not editable from UI                       |
+| Retry prompt                        | **Hard-coded** in `TaskRunner`             | not editable                               |
+| Task prompt structure (title/desc)  | **Hard-coded** in `TaskRunner`             | not editable                               |
+
+---
+
+## 5. Things worth reviewing tomorrow
+
+1. **Task-execution prompt has no frame at all.** Just title + description. Consider whether a thin wrapper (goal / constraints / done-criteria) improves agent focus without bloating small tasks.
+2. **Global DefaultClaudeInstructions is empty out of the box.** This is the cleanest place to put project-wide guardrails (commit format, branch etiquette, verify-before-done, no force push). Right now nothing is there.
+3. **Planning system prompt**:
+   - Typo-level: trailing spaces, inconsistent capitalization ("ALWAYS"/"NEVER"/"Always").
+   - "Your final goal WILL ALWAYS be the creation of Subtasks" conflicts slightly with "Do not create child tasks until the user has approved a design" — rewordable.
+   - Does not state how many subtasks is reasonable, nor how granular.
+   - Does not describe the MCP tool surface; the agent has to discover `mcp__claudedo__*` tools.
+4. **Retry prompt is minimal.** `"Try again and fix the issues."` — could be firmer about not repeating the same failure mode.
+5. **Sub-Tasks block** is dumped as plain checkboxes with no instruction ("please complete all open items", "do them in order", etc.). If the user relies on subtasks for ordering, that intent isn't conveyed.
+6. **ResultSchema is defined but unused.** Decide: drop it, or wire it up (`--output-schema`) and start asking for structured summaries.
+7. **Commit-message template** never tells the agent what `commit_type` to pick when it has flexibility — the value is hard-coded per task. Consider exposing as a prompt hint or inferring from diffs.

+# Planning Sessions — Plan C: UI 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:** Wire the planning-session feature into the UI: context-menu entries, hierarchical display of parent + children, draft styling, unfinished-session dialog, and the `WorkerClient` methods that call the hub endpoints built in Plan B.
+
+**Architecture:** Extend `TaskRowViewModel` with hierarchy-aware flags (`IsChild`, `IsPlanningParent`, `IsExpanded`). `TasksIslandViewModel` builds a flat stream that interleaves parents and their children based on expanded state. Context-menu entries on `TaskRowView` gate on task status. Draft styling lives in the existing island styles. A modal dialog reuses the project's `TaskCompletionSource<T>` pattern.
+
+**Tech Stack:** .NET 8, Avalonia 12, CommunityToolkit.Mvvm (`[ObservableProperty]`, `[RelayCommand]`), compiled bindings, SignalR client.
+
+**Spec reference:** `docs/superpowers/specs/2026-04-23-planning-sessions-design.md` section 6.
+
+---
+
+## Prerequisite Gate
+
+This plan depends on Plan A being merged to `main`. Plan B's interface contract (hub method names, return types) is locked in the spec §6.6 and Plan B task 13 — this plan can proceed in parallel with Plan B.
+
+Before starting:
+
+```bash
+git fetch origin main
+git checkout main
+git pull --ff-only
+ls src/ClaudeDo.Data/Migrations/*AddPlanningSupport*.cs
+```
+
+If the file is missing, wait for Plan A:
+```bash
+while ! ls src/ClaudeDo.Data/Migrations/*AddPlanningSupport*.cs >/dev/null 2>&1; do
+  echo "Waiting for Plan A to merge..."
+  sleep 60
+  git fetch origin main && git pull --ff-only
+done
+```
+
+Then branch:
+```bash
+git checkout -b feat/planning-sessions-ui
+```
+
+**Parallel-with-Plan-B note:** Plan B may not yet be merged when this plan runs. The `WorkerClient` methods in Task 9 will compile against Plan B's SignalR hub method names (they're string-based SignalR invocations), so they don't have a build-time dependency. Runtime end-to-end testing requires Plan B merged; until then, mock-test what's possible and smoke-test manually once both plans land.
+
+---
+
+## File Structure
+

+## Task 1: Extend `TaskRowViewModel`
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs`
+- Create: `tests/ClaudeDo.Worker.Tests/UiVm/TaskRowViewModelPlanningTests.cs`
+
+- [ ] **Step 1: Write failing test for planning flags**
+
+Create the test file. Adapt the existing `TaskRowViewModelTests` pattern (look at `tests/ClaudeDo.Worker.Tests/UiVm/TaskRowViewModelTests.cs` for how VMs are constructed in tests):
+
+```csharp
+using ClaudeDo.Ui.ViewModels.Islands;
+
+namespace ClaudeDo.Worker.Tests.UiVm;
+
+public sealed class TaskRowViewModelPlanningTests
+{
+    [Fact]
+    public void Draft_Status_SetsIsChildFlag_WhenParentIdIsNotNull()
+    {
+        // Adapt the constructor call to your actual TaskRowViewModel signature (see TaskRowViewModelTests).
+        var vm = TestHelpers.MakeRow(
+            status: "draft",
+            parentTaskId: "parent-id");
+
+        Assert.True(vm.IsChild);
+        Assert.False(vm.IsPlanningParent);
+    }
+
+    [Fact]
+    public void Planning_Status_SetsIsPlanningParent()
+    {
+        var vm = TestHelpers.MakeRow(status: "planning", parentTaskId: null);
+
+        Assert.True(vm.IsPlanningParent);
+        Assert.False(vm.IsChild);
+        Assert.Equal("PLANNING", vm.PlanningBadge);
+    }
+
+    [Fact]
+    public void Planned_Status_ShowsPlannedBadge()
+    {
+        var vm = TestHelpers.MakeRow(status: "planned", parentTaskId: null);
+
+        Assert.True(vm.IsPlanningParent);
+        Assert.Equal("PLANNED", vm.PlanningBadge);
+    }
+
+    [Fact]
+    public void NonPlanningStatus_NoBadge()
+    {
+        var vm = TestHelpers.MakeRow(status: "manual", parentTaskId: null);
+
+        Assert.False(vm.IsPlanningParent);
+        Assert.Null(vm.PlanningBadge);
+    }
+}
+
+internal static class TestHelpers
+{
+    public static TaskRowViewModel MakeRow(string status, string? parentTaskId)
+    {
+        // Implement based on actual TaskRowViewModel constructor.
+        // The TaskRowViewModelTests.cs file in the same folder shows the existing pattern.
+        throw new NotImplementedException("Adapt to your TaskRowViewModel constructor");
+    }
+}
+```
+
+Open `tests/ClaudeDo.Worker.Tests/UiVm/TaskRowViewModelTests.cs` first to see how the VM is constructed in tests, then fill in `TestHelpers.MakeRow` accordingly.
+
+- [ ] **Step 2: Run; verify fail**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests --filter "FullyQualifiedName~TaskRowViewModelPlanningTests"`
+Expected: FAIL (properties not yet on VM).
+
+- [ ] **Step 3: Extend the VM**
+
+In `src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs` add the new properties using `[ObservableProperty]`:
+
+```csharp
+[ObservableProperty] private string? parentTaskId;
+[ObservableProperty] private bool isExpanded = true;
+
+public bool IsChild => !string.IsNullOrEmpty(ParentTaskId);
+public bool IsPlanningParent => string.Equals(Status, "planning", StringComparison.OrdinalIgnoreCase)
+                             || string.Equals(Status, "planned", StringComparison.OrdinalIgnoreCase);
+
+public string? PlanningBadge => Status switch
+{
+    string s when string.Equals(s, "planning", StringComparison.OrdinalIgnoreCase) => "PLANNING",
+    string s when string.Equals(s, "planned", StringComparison.OrdinalIgnoreCase) => "PLANNED",
+    _ => null,
+};
+
+public bool IsDraft => string.Equals(Status, "draft", StringComparison.OrdinalIgnoreCase);
+```
+
+Since `IsChild`, `IsPlanningParent`, `PlanningBadge`, and `IsDraft` are computed from other observables, you must raise property-changed notifications when `Status` or `ParentTaskId` changes. Use `[ObservableProperty]` partial methods:
+
+```csharp
+partial void OnStatusChanged(string value)
+{
+    OnPropertyChanged(nameof(IsPlanningParent));
+    OnPropertyChanged(nameof(PlanningBadge));
+    OnPropertyChanged(nameof(IsDraft));
+}
+
+partial void OnParentTaskIdChanged(string? value)
+{
+    OnPropertyChanged(nameof(IsChild));
+}
+```
+
+If the existing VM already has `OnStatusChanged` (check for generator outputs), merge into it rather than duplicating.
+
+- [ ] **Step 4: Run; verify pass**
+
+Expected: PASS.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs tests/ClaudeDo.Worker.Tests/UiVm/TaskRowViewModelPlanningTests.cs
+git commit -m "feat(ui): TaskRowViewModel gains planning hierarchy flags"
+```

+
+## Task 2: `WorkerClient` planning methods
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Services/WorkerClient.cs`
+- Create: DTOs matching Plan B return types (either inline in the client file or new file `src/ClaudeDo.Ui/Services/PlanningDtos.cs`).
+
+- [ ] **Step 1: Add DTOs**
+
+Create `src/ClaudeDo.Ui/Services/PlanningDtos.cs`:
+
+```csharp
+namespace ClaudeDo.Ui.Services;
+
+public sealed record PlanningSessionFilesDto(
+    string SessionDirectory,
+    string McpConfigPath,
+    string SystemPromptPath,
+    string InitialPromptPath);
+
+public sealed record PlanningSessionStartInfo(
+    string ParentTaskId,
+    string WorkingDir,
+    PlanningSessionFilesDto Files);
+
+public sealed record PlanningSessionResumeInfo(
+    string ParentTaskId,
+    string WorkingDir,
+    string ClaudeSessionId,
+    string McpConfigPath);
+```
+
+These field names must match Plan B's `PlanningSessionStartContext` / `PlanningSessionResumeContext` exactly (case-sensitive JSON deserialization through SignalR).
+
+- [ ] **Step 2: Add `WorkerClient` methods**
+
+In `src/ClaudeDo.Ui/Services/WorkerClient.cs`, add:
+
+```csharp
+public Task<PlanningSessionStartInfo> StartPlanningSessionAsync(string taskId, CancellationToken ct = default)
+    => _connection.InvokeAsync<PlanningSessionStartInfo>("StartPlanningSessionAsync", taskId, ct);
+
+public Task<PlanningSessionResumeInfo> ResumePlanningSessionAsync(string taskId, CancellationToken ct = default)
+    => _connection.InvokeAsync<PlanningSessionResumeInfo>("ResumePlanningSessionAsync", taskId, ct);
+
+public Task DiscardPlanningSessionAsync(string taskId, CancellationToken ct = default)
+    => _connection.InvokeAsync("DiscardPlanningSessionAsync", taskId, ct);
+
+public Task<int> FinalizePlanningSessionAsync(string taskId, bool queueAgentTasks = true, CancellationToken ct = default)
+    => _connection.InvokeAsync<int>("FinalizePlanningSessionAsync", taskId, queueAgentTasks, ct);
+
+public Task<int> GetPendingDraftCountAsync(string taskId, CancellationToken ct = default)
+    => _connection.InvokeAsync<int>("GetPendingDraftCountAsync", taskId, ct);
+```
+
+Replace `_connection` with whatever name the existing `WorkerClient` uses for its `HubConnection` field.
+
+- [ ] **Step 3: Build**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj`
+Expected: builds.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Services/PlanningDtos.cs src/ClaudeDo.Ui/Services/WorkerClient.cs
+git commit -m "feat(ui): WorkerClient planning-session methods"
+```

+
+## Task 3: `TasksIslandViewModel` — planning commands + expanded state
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs`
+- Create: `tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs`
+
+- [ ] **Step 1: Add commands to the VM**
+
+In `TasksIslandViewModel.cs`, add:
+
+```csharp
+private readonly Dictionary<string, bool> _expandedState = new();
+
+[RelayCommand]
+private async Task OpenPlanningSessionAsync(TaskRowViewModel? row)
+{
+    if (row is null || !string.Equals(row.Status, "manual", StringComparison.OrdinalIgnoreCase))
+        return;
+    try
+    {
+        await _workerClient.StartPlanningSessionAsync(row.Id);
+    }
+    catch (Exception ex)
+    {
+        await _dialogs.ShowErrorAsync("Could not start planning session", ex.Message);
+    }
+}
+
+[RelayCommand]
+private async Task ResumePlanningSessionAsync(TaskRowViewModel? row)
+{
+    if (row is null || !row.IsPlanningParent) return;
+    try
+    {
+        await _workerClient.ResumePlanningSessionAsync(row.Id);
+    }
+    catch (Exception ex)
+    {
+        await _dialogs.ShowErrorAsync("Could not resume planning session", ex.Message);
+    }
+}
+
+[RelayCommand]
+private async Task DiscardPlanningSessionAsync(TaskRowViewModel? row)
+{
+    if (row is null) return;
+    var confirm = await _dialogs.ConfirmAsync(
+        "Discard planning session?",
+        "This will delete all draft tasks and reset the parent to Manual.");
+    if (!confirm) return;
+    await _workerClient.DiscardPlanningSessionAsync(row.Id);
+}
+
+[RelayCommand]
+private async Task FinalizePlanningSessionAsync(TaskRowViewModel? row)
+{
+    if (row is null) return;
+    await _workerClient.FinalizePlanningSessionAsync(row.Id, queueAgentTasks: true);
+}
+
+[RelayCommand]
+private void ToggleExpand(TaskRowViewModel? row)
+{
+    if (row is null) return;
+    var next = !(_expandedState.TryGetValue(row.Id, out var current) ? current : true);
+    _expandedState[row.Id] = next;
+    row.IsExpanded = next;
+    RebuildFlatStreams();
+}
+
+private void RebuildFlatStreams()
+{
+    // Existing code builds OpenItems/CompletedItems from the task list.
+    // Modify it so that: after emitting a parent, if IsPlanningParent && IsExpanded,
+    // its Draft / Manual / Queued / Running / Done children are emitted next.
+    // Children already know they are children (ParentTaskId != null) and are styled as such.
+}
+```
+
+The existing `RebuildFlatStreams` (or equivalent) probably just groups tasks by status. You need to intersperse the hierarchy:
+
+```csharp
+// Pseudocode — fit to the existing code shape.
+var topLevel = allRows.Where(r => !r.IsChild).OrderBy(r => r.SortOrder);
+var flat = new List<TaskRowViewModel>();
+foreach (var parent in topLevel)
+{
+    flat.Add(parent);
+    if (parent.IsPlanningParent && parent.IsExpanded)
+    {
+        var children = allRows
+            .Where(r => r.ParentTaskId == parent.Id)
+            .OrderBy(r => r.SortOrder)
+            .ToList();
+        flat.AddRange(children);
+    }
+}
+// Then bucket `flat` into OpenItems/CompletedItems like today, preserving order.
+```
+
+Pass dependencies: the VM already has a `WorkerClient` or equivalent — reuse it. Add a dialog service if not already injected:
+
+```csharp
+public interface IDialogService
+{
+    Task<bool> ConfirmAsync(string title, string message);
+    Task ShowErrorAsync(string title, string message);
+}
+```
+
+If an analog already exists (check existing editor dialogs), use it.
+
+- [ ] **Step 2: Write failing VM tests**
+
+`tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs`:
+
+```csharp
+using ClaudeDo.Ui.ViewModels.Islands;
+
+namespace ClaudeDo.Worker.Tests.UiVm;
+
+public sealed class TasksIslandViewModelPlanningTests
+{
+    [Fact]
+    public void ToggleExpand_CollapsesChildrenOfPlanningParent()
+    {
+        // Arrange: create VM with one Planning parent and two Draft children.
+        // Act: call ToggleExpandCommand with the parent.
+        // Assert: flat stream no longer contains the children.
+        // Adapt to how the existing TasksIslandViewModel is instantiated.
+    }
+
+    [Fact]
+    public void OpenPlanningSessionCommand_ManualTaskOnly_CanExecuteTrue()
+    {
+        // Arrange VM with a Manual row.
+        // Assert CanExecute for OpenPlanningSession command is true for Manual rows,
+        // false for Queued/Running/Done/Failed rows.
+    }
+}
+```
+
+These are skeleton tests — implement with the same construction pattern used by the existing `TasksIslandViewModelTests` if one exists, or build a minimal VM fake with a stub `WorkerClient`.
+
+- [ ] **Step 3: Build + test**
+
+Run:
+```bash
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+dotnet test tests/ClaudeDo.Worker.Tests --filter "FullyQualifiedName~TasksIslandViewModelPlanningTests"
+```
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs
+git commit -m "feat(ui): planning commands and expand/collapse in TasksIslandViewModel"
+```
+

+
+## Task 4: `TaskRowView` — indent, chevron, badges, draft styling
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`
+
+- [ ] **Step 1: Wrap the row content with a Grid that has an indent column**
+
+Open `TaskRowView.axaml`. The existing root is likely a `Grid` or `Border`. Replace/refactor the top-level layout to:
+
+```xml
+<Grid ColumnDefinitions="Auto,*">
+    <Border Grid.Column="0"
+            Width="24"
+            IsVisible="{Binding IsChild}">
+        <Rectangle Width="1" Fill="{DynamicResource TextFaintBrush}" HorizontalAlignment="Right" Margin="0,4"/>
+    </Border>
+
+    <Grid Grid.Column="1" ColumnDefinitions="Auto,*,Auto">
+        <!-- Chevron for planning parents -->
+        <Button Grid.Column="0"
+                Classes="icon-btn chevron"
+                Width="18" Height="18"
+                IsVisible="{Binding IsPlanningParent}"
+                Command="{Binding $parent[ItemsControl].((vm:TasksIslandViewModel)DataContext).ToggleExpandCommand}"
+                CommandParameter="{Binding}">
+            <PathIcon Width="10" Height="10">
+                <PathIcon.Data>
+                    <MultiBinding Converter="{StaticResource ChevronDataConverter}">
+                        <Binding Path="IsExpanded"/>
+                    </MultiBinding>
+                </PathIcon.Data>
+            </PathIcon>
+        </Button>
+
+        <!-- existing title/description area -->
+        <StackPanel Grid.Column="1" ...>
+            <!-- existing title binding with added italic when IsDraft -->
+            <TextBlock Text="{Binding Title}"
+                       FontStyle="{Binding IsDraft, Converter={StaticResource BoolToItalicConverter}}"
+                       Opacity="{Binding IsDraft, Converter={StaticResource BoolToDraftOpacityConverter}}" />
+        </StackPanel>
+
+        <!-- Badges -->
+        <StackPanel Grid.Column="2" Orientation="Horizontal" Spacing="4">
+            <Border Classes="badge draft" IsVisible="{Binding IsDraft}">
+                <TextBlock Text="DRAFT"/>
+            </Border>
+            <Border Classes="badge planning" IsVisible="{Binding IsPlanningParent}">
+                <TextBlock Text="{Binding PlanningBadge}"/>
+            </Border>
+        </StackPanel>
+    </Grid>
+</Grid>
+```
+
+This is a structural edit — preserve all existing bindings for status color, completion toggle, star, scheduled-for, etc. The new indentation column and badges are additive.
+
+- [ ] **Step 2: Add the converters**
+
+If `ChevronDataConverter`, `BoolToItalicConverter`, `BoolToDraftOpacityConverter` do not exist, add them to `src/ClaudeDo.Ui/Converters/` (or inline as compiled converters). Example inline:
+
+```xml
+<!-- in UserControl.Resources of TaskRowView.axaml, or in App.axaml for global -->
+<Style Selector="Border.badge">
+    <Setter Property="CornerRadius" Value="3"/>
+    <Setter Property="Padding" Value="4,1"/>
+    <Setter Property="Background" Value="{DynamicResource BadgeBgBrush}"/>
+</Style>
+<Style Selector="Border.badge.draft">
+    <Setter Property="Background" Value="{DynamicResource DraftBadgeBrush}"/>
+</Style>
+<Style Selector="Border.badge.planning">
+    <Setter Property="Background" Value="{DynamicResource PlanningBadgeBrush}"/>
+</Style>
+```
+
+If converters must be code-based, a minimal `BoolToItalicConverter`:
+
+```csharp
+using Avalonia.Data.Converters;
+using Avalonia.Media;
+
+namespace ClaudeDo.Ui.Converters;
+
+public sealed class BoolToItalicConverter : IValueConverter
+{
+    public object Convert(object? value, Type targetType, object? parameter, System.Globalization.CultureInfo culture)
+        => value is true ? FontStyle.Italic : FontStyle.Normal;
+
+    public object ConvertBack(object? value, Type targetType, object? parameter, System.Globalization.CultureInfo culture)
+        => throw new NotSupportedException();
+}
+```
+
+Register in `App.axaml` resources.
+
+- [ ] **Step 3: Build**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj`
+Expected: builds cleanly (XAML compiles).
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml src/ClaudeDo.Ui/Converters/
+git commit -m "feat(ui): TaskRowView hierarchy indentation, chevron, badges, draft italic"
+```
+
+---
+
+## Task 5: `TaskRowView` — planning context-menu entries
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`
+
+- [ ] **Step 1: Locate the existing context menu**
+
+Open `TaskRowView.axaml`. The ContextMenu lives somewhere on the root element or as a `ContextMenu.Items`/`ContextFlyout`. Find the block that defines entries like "Edit", "Run now", etc.
+
+- [ ] **Step 2: Insert planning entries conditionally**
+
+Add within the existing menu (order: after "Run now" and a separator):
+
+```xml
+<MenuItem Header="Open planning Session"
+          Command="{Binding $parent[ItemsControl].((vm:TasksIslandViewModel)DataContext).OpenPlanningSessionCommand}"
+          CommandParameter="{Binding}"
+          IsVisible="{Binding Status, Converter={StaticResource IsManualAndNotChildConverter}, ConverterParameter={Binding IsChild}}"/>
+
+<MenuItem Header="Resume planning Session"
+          Command="{Binding $parent[ItemsControl].((vm:TasksIslandViewModel)DataContext).ResumePlanningSessionCommand}"
+          CommandParameter="{Binding}"
+          IsVisible="{Binding Status, Converter={StaticResource IsPlanningConverter}}"/>
+
+<MenuItem Header="Discard planning session"
+          Command="{Binding $parent[ItemsControl].((vm:TasksIslandViewModel)DataContext).DiscardPlanningSessionCommand}"
+          CommandParameter="{Binding}"
+          IsVisible="{Binding Status, Converter={StaticResource IsPlanningConverter}}"/>
+```
+
+Simpler alternative without multi-condition converters: expose direct bool VM properties that combine the logic — `CanOpenPlanningSession`, `CanResumePlanningSession`, `CanDiscardPlanningSession`:
+
+```csharp
+// In TaskRowViewModel
+public bool CanOpenPlanningSession =>
+    string.Equals(Status, "manual", StringComparison.OrdinalIgnoreCase) && !IsChild;
+
+public bool CanResumeOrDiscardPlanning =>
+    string.Equals(Status, "planning", StringComparison.OrdinalIgnoreCase);
+```
+
+Add `OnPropertyChanged(nameof(CanOpenPlanningSession))` and friends in the status/parent-id partial methods from Task 1. Then the XAML simplifies to:
+
+```xml
+<MenuItem Header="Open planning Session"
+          Command="{Binding ...OpenPlanningSessionCommand}"
+          CommandParameter="{Binding}"
+          IsVisible="{Binding CanOpenPlanningSession}"/>
+```
+
+Use this simpler path — cleaner.
+

+## Task 6: Island styles — draft, badges
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Design/IslandStyles.axaml`
+
+- [ ] **Step 1: Add brushes + styles**
+
+Append within `<Styles.Resources>` or wherever brushes are defined:

+<SolidColorBrush x:Key="PlanningBadgeBrush" Color="#D69E2E"/>
+<SolidColorBrush x:Key="PlannedBadgeBrush" Color="#3182CE"/>

+```xml
+<Style Selector="Border.badge">

+    [ObservableProperty] private int draftCount;
+
+    public TaskCompletionSource<UnfinishedPlanningDialogResult> Result { get; } = new();
+
+    [RelayCommand] private void Resume() => Result.TrySetResult(UnfinishedPlanningDialogResult.Resume);
+    [RelayCommand] private void FinalizeNow() => Result.TrySetResult(UnfinishedPlanningDialogResult.FinalizeNow);
+    [RelayCommand] private void Discard() => Result.TrySetResult(UnfinishedPlanningDialogResult.Discard);
+    [RelayCommand] private void Cancel() => Result.TrySetResult(UnfinishedPlanningDialogResult.Cancel);
+}
+```
+
+- [ ] **Step 2: Create the view**
+
+`src/ClaudeDo.Ui/Views/Dialogs/UnfinishedPlanningDialog.axaml`:
+
+```xml
+<Window xmlns="https://github.com/avaloniaui"
+        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
+        xmlns:vm="using:ClaudeDo.Ui.ViewModels.Dialogs"
+        x:Class="ClaudeDo.Ui.Views.Dialogs.UnfinishedPlanningDialog"
+        x:DataType="vm:UnfinishedPlanningDialogViewModel"
+        Width="440" Height="220"
+        WindowStartupLocation="CenterOwner"
+        CanResize="False"
+        Title="{Binding Title}">
+    <StackPanel Margin="20" Spacing="12">
+        <TextBlock Text="{Binding Title}" FontWeight="Bold" FontSize="15"/>
+        <TextBlock Text="{Binding TaskTitle}" Opacity="0.85"/>
+        <TextBlock>
+            <Run Text="{Binding DraftCount}"/>
+            <Run Text=" draft tasks waiting to be finalized."/>
+        </TextBlock>
+
+        <StackPanel Orientation="Horizontal" Spacing="8" HorizontalAlignment="Right">
+            <Button Content="Discard" Command="{Binding DiscardCommand}"/>
+            <Button Content="Finalize now" Command="{Binding FinalizeNowCommand}"/>
+            <Button Content="Resume" Classes="accent" Command="{Binding ResumeCommand}"/>
+        </StackPanel>
+    </StackPanel>
+</Window>
+```
+
+`UnfinishedPlanningDialog.axaml.cs`:
+
+```csharp
+using Avalonia.Controls;
+using Avalonia.Markup.Xaml;
+
+namespace ClaudeDo.Ui.Views.Dialogs;
+
+public partial class UnfinishedPlanningDialog : Window
+{
+    public UnfinishedPlanningDialog()
+    {
+        InitializeComponent();
+    }
+}
+```
+
+- [ ] **Step 3: Wire into `TasksIslandViewModel`**
+
+When the user right-clicks a `Planning` row OR when the app starts and a `Planning` row is present, show the dialog. Add a helper in the VM:
+
+```csharp
+private async Task<UnfinishedPlanningDialogResult> AskUnfinishedPlanningAsync(TaskRowViewModel row)
+{
+    var dialogVm = new UnfinishedPlanningDialogViewModel
+    {
+        TaskTitle = row.Title,
+        DraftCount = await _workerClient.GetPendingDraftCountAsync(row.Id),
+    };
+    var dlg = new UnfinishedPlanningDialog { DataContext = dialogVm };
+    _ = dlg.ShowDialog(_ownerWindow);
+    return await dialogVm.Result.Task;
+}
+```
+
+Replace the direct resume/discard/finalize commands (from Task 3) with calls that first pop this dialog and dispatch based on result. For example:
+
+```csharp
+[RelayCommand]
+private async Task ResumePlanningSessionAsync(TaskRowViewModel? row)
+{
+    if (row is null || !row.IsPlanningParent) return;
+    var choice = await AskUnfinishedPlanningAsync(row);
+    switch (choice)
+    {
+        case UnfinishedPlanningDialogResult.Resume:
+            await _workerClient.ResumePlanningSessionAsync(row.Id);
+            break;
+        case UnfinishedPlanningDialogResult.FinalizeNow:
+            await _workerClient.FinalizePlanningSessionAsync(row.Id);
+            break;
+        case UnfinishedPlanningDialogResult.Discard:
+            await _workerClient.DiscardPlanningSessionAsync(row.Id);
+            break;
+    }
+}
+```
+
+- [ ] **Step 4: Build + manual run**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj`
+Expected: builds.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/Dialogs/UnfinishedPlanningDialog.axaml src/ClaudeDo.Ui/Views/Dialogs/UnfinishedPlanningDialog.axaml.cs src/ClaudeDo.Ui/ViewModels/Dialogs/UnfinishedPlanningDialogViewModel.cs src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs

+
+## Task 8: TasksIslandView — wire new templates
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/Islands/TasksIslandView.axaml`
+
+- [ ] **Step 1: No structural change required**
+
+The hierarchy is already handled by `TasksIslandViewModel.RebuildFlatStreams` interleaving children into `OpenItems`/`CompletedItems`. The existing `ItemsControl` bindings in `TasksIslandView` automatically pick up the new rows. Indentation/chevron/badge rendering is entirely inside `TaskRowView` (Task 4).
+
+Verify the view does not have any logic that filters out children based on `ParentTaskId IS NOT NULL` today. If it does, remove that filter — the VM is now authoritative about what's in the stream.
+
+- [ ] **Step 2: Build + manual check**
+
+Launch the UI, create a manual task, and manually update its status to `Planning` in the DB (or wait for Plan B). Create one child in DB. Verify indentation and chevron render.
+
+- [ ] **Step 3: Commit (if any change was made)**
+
+```bash
+git add src/ClaudeDo.Ui/Views/Islands/TasksIslandView.axaml
+git commit -m "chore(ui): verify tasks view renders hierarchy via flat stream"
+```
+
+If no change — skip the commit.
+
+---
+
+## Task 9: Delete-with-children handling
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs` (existing delete command)
+
+- [ ] **Step 1: Catch `DbUpdateException` from delete**
+
+Find the existing delete command. Wrap the repository/hub call:
+
+```csharp
+[RelayCommand]
+private async Task RemoveAsync(TaskRowViewModel? row)
+{
+    if (row is null) return;
+    try
+    {
+        await _workerClient.DeleteTaskAsync(row.Id);
+    }
+    catch (HubException ex) when (ex.Message.Contains("foreign key", StringComparison.OrdinalIgnoreCase)
+                                || ex.Message.Contains("FOREIGN KEY", StringComparison.OrdinalIgnoreCase)
+                                || ex.Message.Contains("Restrict", StringComparison.OrdinalIgnoreCase))
+    {
+        var childrenCount = 1; // or query via a new hub method if exact count matters
+        var choice = await _dialogs.ConfirmAsync(
+            "Cannot delete",
+            $"This task has child tasks. Delete all including children?");
+        if (!choice) return;
+        // Recursive delete — iterate children first. For v1 MVP, instruct user to
+        // discard the planning session first. Simpler, safer.
+        await _dialogs.ShowErrorAsync(
+            "Cannot delete",
+            "Discard the planning session or delete child tasks manually first.");
+    }
+}
+```
+
+**Simplification for v1:** do not implement "Delete all including children" yet. Show an error instructing the user to discard the planning session or delete children first. This avoids an additional hub endpoint and keeps Plan C bounded.
+
+- [ ] **Step 2: Build**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj`
+Expected: builds.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs
+git commit -m "feat(ui): friendly error when deleting task with children"
+```
+
+---
+
+## Task 10: Manual smoke test + final verification
+
+**Files:** none
+
+- [ ] **Step 1: Full test run**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests`
+Expected: all tests pass.
+
+- [ ] **Step 2: Build the full app**
+
+Run:
+```bash
+dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj
+```
+Expected: all succeed.
+
+- [ ] **Step 3: Manual smoke test (requires Plan B merged)**
+
+1. Launch the app.
+2. Create a Manual task with a title and some TODO-style description.
+3. Right-click → "Open planning Session".
+4. Verify Windows Terminal opens with Claude CLI running.
+5. In the terminal, ask Claude to create two child tasks (`mcp__claudedo__create_child_task`).
+6. Watch the UI: drafts appear under the parent (italic, grey, badge DRAFT).
+7. Ask Claude to `finalize`.
+8. Verify drafts become Manual/Queued children, parent flips to PLANNED badge.
+9. Close terminal without finalize on a new planning task; right-click the Planning task: dialog appears with Resume/Finalize/Discard.
+
+- [ ] **Step 4: Document any UI tweaks needed in `docs/open.md`**
+
+Add a checklist item under UI verification for planning session visuals.
+
+- [ ] **Step 5: Final commit**
+
+```bash
+git add docs/open.md
+git commit -m "docs(open): add planning-session manual verification checklist"
+```
+
+---
+
+## Out of scope for Plan C
+
+- Recursive delete of parent-with-children via UI (error-only in v1).
+- Collapse-state persistence across app restarts (in-memory only).
+- Keyboard shortcut for "Open planning Session".
+- Visual differentiation for PLANNED parents beyond a badge (e.g., subtle background tint) — can be added later if visually needed.

+# Worker Log Footer 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:** Surface important Worker lifecycle events in the UI footer as a single rotating, color-coded line that auto-hides after 30s of silence.
+
+**Architecture:** Add `WorkerLogLevel` enum in shared `ClaudeDo.Data` project. `HubBroadcaster` gets a `WorkerLog(message, level, timestampUtc)` SignalR event. Seven emit sites in `TaskRunner`, `TaskMergeService`, `TaskResetService` (callers of `WorktreeManager`, not WorktreeManager itself — they have the task title in scope). UI side: `WorkerClient` surfaces a `WorkerLogReceived` event; footer state lives on `IslandsShellViewModel` (existing root VM for `MainWindow`, also owns connection state); `System.Timers.Timer` clears the line after 30s; a `WorkerLogLevelToBrushConverter` maps level → brush in XAML.
+
+**Tech Stack:** .NET 8, ASP.NET Core SignalR, Avalonia 12, CommunityToolkit.Mvvm, xUnit.
+
+**Spec:** `docs/superpowers/specs/2026-04-23-worker-log-footer-design.md`
+
+**Deviation from spec:** Spec names `WorktreeManager.CreateAsync` / `DiscardAsync` as emit sites. In practice, `WorktreeManager` has only the task ID in scope; its callers (`TaskRunner`, `TaskResetService`) have the title. Emitting from callers avoids adding constructor dependencies to `WorktreeManager` and produces identical user-visible behavior.
+
+**Build note:** Per project convention, `dotnet build ClaudeDo.slnx` fails on .NET 8 — always build individual csprojs.
+
+---
+
+### Task 1: Add `WorkerLogLevel` enum (shared contract)
+
+**Files:**
+- Create: `src/ClaudeDo.Data/Models/WorkerLogLevel.cs`
+
+- [ ] **Step 1: Write the enum**
+
+```csharp
+namespace ClaudeDo.Data.Models;
+
+public enum WorkerLogLevel
+{
+    Info,
+    Success,
+    Warn,
+    Error,
+}
+```
+
+- [ ] **Step 2: Build Data project**
+
+Run: `dotnet build src/ClaudeDo.Data/ClaudeDo.Data.csproj`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/ClaudeDo.Data/Models/WorkerLogLevel.cs
+git commit -m "feat(data): add WorkerLogLevel enum"
+```
+
+---
+
+### Task 2: Add `WorkerLog` broadcaster method + SignalR JSON enum-as-string
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Hub/HubBroadcaster.cs` (append method)
+- Modify: `src/ClaudeDo.Worker/Program.cs` (line ~23 — the `AddSignalR()` call)
+
+- [ ] **Step 1: Add enum-as-string serialization**
+
+Replace:
+```csharp
+builder.Services.AddSignalR();
+```
+with:
+```csharp
+builder.Services.AddSignalR().AddJsonProtocol(options =>
+{
+    options.PayloadSerializerOptions.Converters.Add(new System.Text.Json.Serialization.JsonStringEnumConverter());
+});
+```
+
+- [ ] **Step 2: Add `WorkerLog` method to `HubBroadcaster`**
+
+Add the following method inside `HubBroadcaster` class (after the existing `RunCreated` method):
+
+```csharp
+public Task WorkerLog(string message, WorkerLogLevel level, DateTime timestampUtc) =>
+    _hub.Clients.All.SendAsync("WorkerLog", message, level, timestampUtc);
+```
+
+Add to the using block at top of file (if not already present):
+```csharp
+using ClaudeDo.Data.Models;
+```
+
+- [ ] **Step 3: Build**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Hub/HubBroadcaster.cs src/ClaudeDo.Worker/Program.cs
+git commit -m "feat(worker): add WorkerLog SignalR event"
+```
+
+---
+
+### Task 3: Emit `WorkerLog` from `TaskRunner`
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Runner/TaskRunner.cs`
+
+Four emit sites in this file:
+1. **Created worktree** — right after `_wtManager.CreateAsync` succeeds (around line 69).
+2. **Started Claude** — just before invoking Claude process.
+3. **Committed changes** — after auto-commit (before the `WorktreeUpdated` broadcast around line 318).
+4. **Finished** — at both success (line 330) and failure paths, mirroring the existing `TaskFinished` call.
+
+- [ ] **Step 1: Add using for `WorkerLogLevel`**
+
+Ensure `TaskRunner.cs` has at the top:
+```csharp
+using ClaudeDo.Data.Models;
+```
+
+- [ ] **Step 2: Emit "Created worktree"**
+
+After the line `wtCtx = await _wtManager.CreateAsync(task, list, ct);` (around line 69), add:
+```csharp
+await _broadcaster.WorkerLog($"Created worktree for \"{task.Title}\"", WorkerLogLevel.Info, DateTime.UtcNow);
+```
+(Place inside the same `if` branch that called `CreateAsync`, after the assignment.)
+
+- [ ] **Step 3: Emit "Started Claude"**
+
+Locate the point just before `ClaudeProcess` is invoked (search for where `ClaudeProcess` or `RunProcessAsync` is called). Just before the invocation, add:
+```csharp
+await _broadcaster.WorkerLog($"Started Claude for \"{task.Title}\"", WorkerLogLevel.Info, DateTime.UtcNow);
+```
+
+- [ ] **Step 4: Emit "Committed changes"**
+
+Locate the auto-commit code path (around line 318, just before `await _broadcaster.WorktreeUpdated(task.Id);`). Add immediately before that call:
+```csharp
+await _broadcaster.WorkerLog($"Committed changes in \"{task.Title}\"", WorkerLogLevel.Info, DateTime.UtcNow);
+```
+
+- [ ] **Step 5: Emit "Finished (done)"**
+
+Find the success finish path (around line 330, where `TaskFinished` is broadcast with status `"done"`). Add immediately before that call:
+```csharp
+await _broadcaster.WorkerLog($"Finished \"{task.Title}\" (done)", WorkerLogLevel.Success, DateTime.UtcNow);
+```
+
+- [ ] **Step 6: Emit "Finished (failed)"**
+
+Find the failure path (search for `TaskFinished` with status `"failed"`). Add immediately before:
+```csharp
+await _broadcaster.WorkerLog($"Finished \"{task.Title}\" (failed)", WorkerLogLevel.Error, DateTime.UtcNow);
+```
+
+- [ ] **Step 7: Build**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 8: Run existing Worker tests (no regressions)**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj`
+Expected: All tests pass.
+
+- [ ] **Step 9: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Runner/TaskRunner.cs
+git commit -m "feat(worker): emit WorkerLog events from TaskRunner"
+```
+
+---
+
+### Task 4: Emit `WorkerLog` from `TaskMergeService` and `TaskResetService`
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Services/TaskMergeService.cs`
+- Modify: `src/ClaudeDo.Worker/Services/TaskResetService.cs`
+
+Both services already have `HubBroadcaster` injected (`_broadcaster`). Both already load the task entity (needed for title).
+
+- [ ] **Step 1: Add using in both files**
+
+Add to the top of each file (if not already present):
+```csharp
+using ClaudeDo.Data.Models;
+```
+
+- [ ] **Step 2: Emit "Merged" in `TaskMergeService.MergeAsync`**
+
+Locate the existing log line around line 137:
+```csharp
+_logger.LogInformation(
+    "Merged task {TaskId} branch {Branch} into {Target} (remove worktree: {Remove})",
+    ...);
+```
+
+Immediately after it (before `return new MergeResult(...)` on line 140), add:
+```csharp
+await _broadcaster.WorkerLog($"Merged \"{task.Title}\" into {targetBranch}", WorkerLogLevel.Success, DateTime.UtcNow);
+```
+Use whatever variable names `task` and `targetBranch` are in scope — adjust to match the actual local names at that site.
+
+- [ ] **Step 3: Emit "Discarded" in `TaskResetService.ResetAsync`**
+
+Locate the call `await _wtManager.DiscardAsync(wt, list.WorkingDir, ct);` (line 53). Immediately after it, add:
+```csharp
+await _broadcaster.WorkerLog($"Discarded worktree for \"{task.Title}\"", WorkerLogLevel.Warn, DateTime.UtcNow);
+```
+
+- [ ] **Step 4: Emit "Reset" in `TaskResetService.ResetAsync`**
+
+Locate the existing line `_logger.LogInformation("Reset task {TaskId} to Manual ...` (line 66). Immediately after it, add:
+```csharp
+await _broadcaster.WorkerLog($"Reset \"{task.Title}\"", WorkerLogLevel.Warn, DateTime.UtcNow);
+```
+
+- [ ] **Step 5: Build**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 6: Run existing Worker tests**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj`
+Expected: All tests pass.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Services/TaskMergeService.cs src/ClaudeDo.Worker/Services/TaskResetService.cs
+git commit -m "feat(worker): emit WorkerLog for merge, discard, reset"
+```
+
+---
+
+### Task 5: Add `WorkerLogEntry` record + `WorkerLogReceived` event on `WorkerClient`
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Services/WorkerClient.cs`
+
+- [ ] **Step 1: Add using for `WorkerLogLevel`**
+
+Add at the top of `WorkerClient.cs`:
+```csharp
+using ClaudeDo.Data.Models;
+```
+
+- [ ] **Step 2: Declare the `WorkerLogEntry` record**
+
+Add at the top of the file (above or below the `WorkerClient` class, same namespace):
+```csharp
+public sealed record WorkerLogEntry(string Message, WorkerLogLevel Level, DateTime TimestampUtc);
+```
+
+- [ ] **Step 3: Add the event field**
+
+Alongside the other `public event Action<...>?` declarations (around lines 42-48), add:
+```csharp
+public event Action<WorkerLogEntry>? WorkerLogReceivedEvent;
+```
+
+- [ ] **Step 4: Register the SignalR handler**
+
+Alongside the other `_hub.On<...>` registrations (around lines 80-117), add:
+```csharp
+_hub.On<string, WorkerLogLevel, DateTime>("WorkerLog", (message, level, timestampUtc) =>
+{
+    WorkerLogReceivedEvent?.Invoke(new WorkerLogEntry(message, level, timestampUtc));
+});
+```
+
+- [ ] **Step 5: Build**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj`
+Expected: Build succeeded, 0 errors.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Services/WorkerClient.cs
+git commit -m "feat(ui): subscribe to WorkerLog SignalR event"
+```
+
+---
+
+### Task 6: Create `ClaudeDo.Ui.Tests` project and add `WorkerLogLevelToBrushConverter`
+
+**Files:**
+- Create: `src/ClaudeDo.Ui/Converters/WorkerLogLevelToBrushConverter.cs`
+- Modify: `src/ClaudeDo.Ui/App.axaml` (register converter as resource)
+- Create: `tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj`
+- Create: `tests/ClaudeDo.Ui.Tests/WorkerLogLevelToBrushConverterTests.cs`
+
+- [ ] **Step 1: Write the converter**
+
+Create `src/ClaudeDo.Ui/Converters/WorkerLogLevelToBrushConverter.cs`:
+
+```csharp
+using System;
+using System.Globalization;
+using Avalonia;
+using Avalonia.Data.Converters;
+using Avalonia.Media;
+using ClaudeDo.Data.Models;
+
+namespace ClaudeDo.Ui.Converters;
+
+public sealed class WorkerLogLevelToBrushConverter : IValueConverter
+{
+    private static readonly IBrush SuccessBrush = new SolidColorBrush(Color.Parse("#4CAF50"));
+    private static readonly IBrush WarnBrush    = new SolidColorBrush(Color.Parse("#FFA726"));
+    private static readonly IBrush ErrorBrush   = new SolidColorBrush(Color.Parse("#EF5350"));
+    private static readonly IBrush InfoFallback = new SolidColorBrush(Color.Parse("#888888"));
+
+    public object? Convert(object? value, Type targetType, object? parameter, CultureInfo culture)
+    {
+        if (value is not WorkerLogLevel level)
+            return AvaloniaProperty.UnsetValue;
+
+        return level switch
+        {
+            WorkerLogLevel.Success => SuccessBrush,
+            WorkerLogLevel.Warn    => WarnBrush,
+            WorkerLogLevel.Error   => ErrorBrush,
+            WorkerLogLevel.Info    => ResolveInfoBrush(),
+            _                      => AvaloniaProperty.UnsetValue,
+        };
+    }
+
+    public object? ConvertBack(object? value, Type targetType, object? parameter, CultureInfo culture) =>
+        throw new NotSupportedException();
+
+    private static IBrush ResolveInfoBrush()
+    {
+        if (Application.Current is { } app &&
+            app.Resources.TryGetResource("TextDimBrush", app.ActualThemeVariant, out var res) &&
+            res is IBrush brush)
+        {
+            return brush;
+        }
+        return InfoFallback;
+    }
+}
+```
+
+- [ ] **Step 2: Register converter in `App.axaml`**
+
+Open `src/ClaudeDo.Ui/App.axaml`. Inside the `<Application.Resources>` section (add one if missing), add alongside any existing converter entries:
+
+```xml
+<converters:WorkerLogLevelToBrushConverter x:Key="WorkerLogLevelToBrush"/>
+```
+
+Ensure the `xmlns:converters="using:ClaudeDo.Ui.Converters"` namespace is declared at the root `<Application>` element. If other converters (e.g. `StatusColorConverter`) are already resources in `App.axaml` follow the same pattern; if they're declared per-view, declare this converter at the top of `MainWindow.axaml` in Task 8 instead.
+
+- [ ] **Step 3: Create UI test project**
+
+Create `tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj`:
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+  <PropertyGroup>
+    <TargetFramework>net8.0</TargetFramework>

+### Task 7: Add footer state + 30s auto-clear timer to `IslandsShellViewModel`
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/IslandsShellViewModel.cs`
+- Create: `tests/ClaudeDo.Ui.Tests/IslandsShellViewModelWorkerLogTests.cs`
+
+Timer uses `System.Timers.Timer` (not `DispatcherTimer`) so unit tests don't need an Avalonia dispatcher. The elapsed callback marshals to the UI thread via `Dispatcher.UIThread.Post` when the dispatcher is available; in tests the VM logic under test sets properties directly so no marshalling is needed.
+
+- [ ] **Step 1: Write the failing tests**
+
+Create `tests/ClaudeDo.Ui.Tests/IslandsShellViewModelWorkerLogTests.cs`:
+
+```csharp

+        // The real constructor requires island VMs + WorkerClient. These tests
+        // only exercise the WorkerLog handling, so we use a test-only constructor
+        // that bypasses the sub-VMs. Add `internal IslandsShellViewModel()` for tests.
+        IslandsShellViewModel.CreateForTests();
+
+    [Fact]

+
+        Assert.StartsWith(expectedLocalHhmm + " · ", vm.WorkerLogText);

+}
+```
+
+- [ ] **Step 2: Run tests to confirm they fail to compile**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj`
+Expected: Build errors — `CreateForTests`, `OnWorkerLogReceived`, `ClearWorkerLog`, `IsWorkerLogVisible`, `WorkerLogText`, `WorkerLogLevel` do not yet exist.
+
+- [ ] **Step 3: Implement on `IslandsShellViewModel`**
+
+Open `src/ClaudeDo.Ui/ViewModels/IslandsShellViewModel.cs`. Add `using`s if missing:
+
+```csharp
+using System.Timers;
+using Avalonia.Threading;
+using ClaudeDo.Data.Models;
+using ClaudeDo.Ui.Services;
+```
+
+Inside the class, add:
+
+```csharp
+[ObservableProperty] private string? workerLogText;
+[ObservableProperty] private WorkerLogLevel workerLogLevel;
+[ObservableProperty] private bool isWorkerLogVisible;
+
+private readonly Timer _workerLogTimer = new(TimeSpan.FromSeconds(30).TotalMilliseconds)
+{
+    AutoReset = false,
+};
+
+internal static IslandsShellViewModel CreateForTests() =>
+    (IslandsShellViewModel)System.Runtime.Serialization.FormatterServices
+        .GetUninitializedObject(typeof(IslandsShellViewModel));
+```
+
+(If `FormatterServices` is unavailable under `net8.0`, instead add a parameterless `internal IslandsShellViewModel() {}` constructor guarded for tests only.)
+
+In the existing real constructor, wire up subscription (after the line `Worker.PropertyChanged += ...` block, around line 63-70):
+
+```csharp
+Worker.WorkerLogReceivedEvent += OnWorkerLogReceived;
+_workerLogTimer.Elapsed += (_, _) =>
+{
+    if (Dispatcher.UIThread.CheckAccess()) ClearWorkerLog();
+    else Dispatcher.UIThread.Post(ClearWorkerLog);
+};
+```
+
+Add the methods the tests call:
+
+```csharp
+public void OnWorkerLogReceived(WorkerLogEntry entry)
+{
+    var hhmm = entry.TimestampUtc.ToLocalTime().ToString("HH:mm");
+    WorkerLogText = $"{hhmm} · {entry.Message}";
+    WorkerLogLevel = entry.Level;
+    IsWorkerLogVisible = true;
+
+    _workerLogTimer.Stop();
+    _workerLogTimer.Start();
+}
+
+public void ClearWorkerLog()
+{
+    IsWorkerLogVisible = false;
+    WorkerLogText = null;
+}
+```
+
+- [ ] **Step 4: Run tests**
+
+Run: `dotnet test tests/ClaudeDo.Ui.Tests/ClaudeDo.Ui.Tests.csproj`
+Expected: All tests pass (5 converter + 4 VM = 9 tests).
+
+- [ ] **Step 5: Build the UI project as a sanity check**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj`
+Expected: Build succeeded.
+

+
+```bash

+### Task 8: Update `MainWindow.axaml` footer — dock log line right
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/MainWindow.axaml` (lines 104-135 — the footer `Border`)
+
+- [ ] **Step 1: Add the converter resource to the window (if not already in App.axaml)**
+
+If Task 6 declared the converter in `App.axaml`, skip this step. Otherwise, add a `<Window.Resources>` block near the top of `MainWindow.axaml`:
+```xml
+<Window.Resources>
+    <converters:WorkerLogLevelToBrushConverter x:Key="WorkerLogLevelToBrush"/>
+</Window.Resources>
+```
+Ensure `xmlns:converters="using:ClaudeDo.Ui.Converters"` is declared on the root `<Window>`.
+
+- [ ] **Step 2: Replace the footer body**
+
+Replace the existing footer `<Border Grid.Row="2" ...>` inner contents (the `<StackPanel>` at lines 109-134) with:
+
+```xml
+<DockPanel LastChildFill="True" Margin="14,0">
+    <!-- Left: connection pill -->
+    <StackPanel DockPanel.Dock="Left" Orientation="Horizontal" Spacing="7"
+                VerticalAlignment="Center">
+        <Ellipse Width="7" Height="7" Fill="#4CAF50"

+        <Ellipse Width="7" Height="7" Fill="#FFA726"
+                 IsVisible="{Binding Worker.IsReconnecting}"/>
+        <Ellipse Width="7" Height="7" Fill="#EF5350"
+                 IsVisible="{Binding IsOffline}"/>
+        <TextBlock Text="{Binding ConnectionText, Converter={StaticResource UpperCase}}"
+                   FontFamily="{DynamicResource MonoFont}"
+                   FontSize="10"
+                   LetterSpacing="1.4"
+                   Foreground="{DynamicResource TextDimBrush}"
+                   VerticalAlignment="Center"/>
+    </StackPanel>
+
+    <!-- Right: worker log line -->
+    <TextBlock DockPanel.Dock="Right"
+               Text="{Binding WorkerLogText}"
+               IsVisible="{Binding IsWorkerLogVisible}"
+               Foreground="{Binding WorkerLogLevel, Converter={StaticResource WorkerLogLevelToBrush}}"
+               FontFamily="{DynamicResource MonoFont}"
+               FontSize="10"
+               LetterSpacing="1.4"
+               TextTrimming="CharacterEllipsis"
+               VerticalAlignment="Center"/>
+
+    <!-- Spacer (fills remaining space between pill and log) -->
+    <Panel/>
+</DockPanel>
+```
+
+- [ ] **Step 3: Build the UI**
+
+Run: `dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj`
+Expected: Build succeeded, 0 errors. No XAML compilation errors.
+
+- [ ] **Step 4: Build the full app (entry point)**
+
+Run: `dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj`
+Expected: Build succeeded.
+
+- [ ] **Step 5: Manual smoke test**
+
+Start the Worker and the App (two separate processes per CLAUDE.md).
+
+Exercise each event and confirm the footer line appears with the expected color and copy:
+
+1. Start a task → expect `HH:MM · Created worktree for "<title>"` (dim/info).
+2. Observe while Claude runs → expect `HH:MM · Started Claude for "<title>"` (dim/info).
+3. Task commits → expect `HH:MM · Committed changes in "<title>"` (dim/info).
+4. Task finishes successfully → expect `HH:MM · Finished "<title>" (done)` (green).
+5. Trigger a failing task → expect `HH:MM · Finished "<title>" (failed)` (red).
+6. Reset a failed task → expect `HH:MM · Discarded worktree for "<title>"` (amber) followed by `HH:MM · Reset "<title>"` (amber).
+7. Merge a completed task → expect `HH:MM · Merged "<title>" into <branch>` (green).
+8. Wait 30s with no new events → footer log line disappears (connection pill remains).
+9. Trigger a burst of 3 events in quick succession → only the most recent is shown; timer resets on each.
+10. Long task title (≥60 chars) → line is ellipsized, connection pill on the left remains fully visible.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/MainWindow.axaml
+git commit -m "feat(ui): show worker log line in footer"

+## Self-Review
+
+- **Spec coverage:**
+    - Enum `WorkerLogLevel` in `ClaudeDo.Data` — Task 1 ✓
+    - SignalR enum-as-string — Task 2 ✓
+    - `HubBroadcaster.WorkerLog` — Task 2 ✓
+    - 7 emit sites with correct level mapping — Tasks 3, 4 ✓
+    - `WorkerClient.WorkerLogReceived` event + `WorkerLogEntry` record — Task 5 ✓
+    - `WorkerLogLevelToBrushConverter` with unit tests — Task 6 ✓
+    - Footer VM state + 30s timer + tests — Task 7 ✓
+    - Footer XAML (DockPanel, connection left, log right, level-based color, ellipsis) — Task 8 ✓
+    - Out-of-scope items (history drawer, filtering, persistence) — correctly omitted ✓
+
+- **Placeholder scan:** No "TBD" / "handle edge cases" / "similar to Task N". All code is inline.
+
+- **Type consistency:** `WorkerLogEntry(Message, Level, TimestampUtc)` — same signature used in Task 5 (declaration), Task 7 (consumer tests + VM). `WorkerLog(message, level, timestampUtc)` — same signature in Task 2 (broadcaster) and Tasks 3-4 (callers). `OnWorkerLogReceived` / `ClearWorkerLog` / `IsWorkerLogVisible` / `WorkerLogText` / `WorkerLogLevel` — consistent between Task 7 test and Task 7 implementation.

+# Planning UX Polish + Sequential Subtask Queue — 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:** Add sequential execution of planning subtasks (new `Waiting` status, context-menu trigger, worker-side chain advancement) plus three small UX changes (auto-collapse done planning parents in the task list, collapsible Description in the Details pane, narrower island GridSplitters).
+
+**Architecture:** Foundation first — add the new `Waiting` enum value and its surface in the UI (chip, virtual-queued filter, row plumbing). Then ship the three UI polish items independently. Finally build the worker-side chain coordinator behind TDD and wire up the SignalR method + context-menu entry.
+
+**Tech Stack:** .NET 8, Avalonia 12, CommunityToolkit.Mvvm, EF Core (Sqlite), SignalR, xUnit.
+
+**Spec:** `docs/superpowers/specs/2026-04-24-planning-ux-and-sequential-subtasks-design.md`
+
+---
+
+## Task 1: Add `Waiting` status to the enum
+
+**Files:**
+- Modify: `src/ClaudeDo.Data/Models/TaskEntity.cs` (TaskStatus enum)
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs` (chip class switch)
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs` (virtual-queued match predicate)
+
+- [ ] **Step 1: Add `Waiting` to the enum**
+
+Append `Waiting` as the last value (keeps existing numeric slots stable for any int-serialized rows).
+
+`src/ClaudeDo.Data/Models/TaskEntity.cs`:
+
+```csharp
+public enum TaskStatus
+{
+    Manual,
+    Queued,
+    Running,
+    Done,
+    Failed,
+    Planning,
+    Planned,
+    Draft,
+    Waiting,
+}
+```
+
+- [ ] **Step 2: Extend `StatusChipClass` switch in TaskRowViewModel**
+
+`src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs` — update the switch:
+
+```csharp
+public string StatusChipClass => Status switch
+{
+    TaskStatus.Running => "running",
+    TaskStatus.Failed  => "error",
+    TaskStatus.Done    => "review",
+    TaskStatus.Queued  => "queued",
+    TaskStatus.Waiting => "waiting",
+    _                  => "idle",
+};
+```
+
+- [ ] **Step 3: Add `IsWaiting` and include it in virtual-queued matching**
+
+In the same `TaskRowViewModel.cs`, add alongside `IsQueued`:
+
+```csharp
+public bool IsWaiting => Status == TaskStatus.Waiting;
+```
+
+In `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs`, find the `TaskMatchesList` static method and update the `virtual:queued` branch so tasks in `Waiting` also match. Locate the existing match for `ListKind.Virtual when list.Id == "virtual:queued"` and change it to match `t.Status == TaskStatus.Queued || t.Status == TaskStatus.Waiting`. If the existing line reads `t.Status == TaskStatus.Queued` exactly, replace it with `t.Status == TaskStatus.Queued || t.Status == TaskStatus.Waiting`.
+
+- [ ] **Step 4: Build**
+
+Run:
+
+```bash
+dotnet build src/ClaudeDo.Data/ClaudeDo.Data.csproj
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+```
+
+Expected: both build with 0 errors. Existing warnings OK.
+
+- [ ] **Step 5: Commit**
+
+```bash
+git add src/ClaudeDo.Data/Models/TaskEntity.cs \
+        src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs \

+
+## Task 2: Narrower island GridSplitters
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/Views/MainWindow.axaml` (lines 158 and 170)
+
+- [ ] **Step 1: Halve the splitter width**
+
+Both `GridSplitter` elements currently use `Width="5"`. Change both to `Width="3"`. Leave all other attributes untouched.
+
+- [ ] **Step 2: Build**
+
+```bash
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/Views/MainWindow.axaml
+git commit -m "style(ui): narrow island GridSplitters from 5 to 3"
+```
+

+
+## Task 3: Collapsible Description section in Details pane
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs`
+- Modify: `src/ClaudeDo.Ui/Views/Islands/DetailsIslandView.axaml`
+
+- [ ] **Step 1: Add observable flag + toggle command**
+
+In `DetailsIslandViewModel.cs`, add beside the existing editable fields:
+
+```csharp
+[ObservableProperty] private bool _isDescriptionExpanded = true;
+
+[RelayCommand]
+private void ToggleDescriptionExpanded() => IsDescriptionExpanded = !IsDescriptionExpanded;
+```
+
+- [ ] **Step 2: Reset flag when a new task is loaded**
+
+Find the method that handles a new `Task` being bound (the existing `OnTaskChanged` / `Bind` path — it's the spot that already sets `EditableTitle`, `EditableDescription`, etc.). At the start of the load path where fields get reset, add:
+
+```csharp
+IsDescriptionExpanded = true;
+```
+
+(If the reset is scattered, put it next to the `EditableDescription = ""` assignment.)
+
+- [ ] **Step 3: Wrap the description TextBox in a collapsible section**
+
+In `DetailsIslandView.axaml`, locate the description TextBox. Wrap it so it looks like:
+
+```xml
+<StackPanel Spacing="4">
+  <Button Classes="flat"
+          Command="{Binding ToggleDescriptionExpandedCommand}"
+          HorizontalAlignment="Stretch"
+          HorizontalContentAlignment="Left"
+          Padding="0">
+    <StackPanel Orientation="Horizontal" Spacing="6">
+      <PathIcon Width="10" Height="10"
+                Data="{StaticResource Icon.ChevronDown}"
+                IsVisible="{Binding IsDescriptionExpanded}"/>
+      <PathIcon Width="10" Height="10"
+                Data="{StaticResource Icon.ChevronRight}"
+                IsVisible="{Binding !IsDescriptionExpanded}"/>
+      <TextBlock Classes="eyebrow" Text="DESCRIPTION"/>
+    </StackPanel>
+  </Button>
+
+  <!-- existing description TextBox goes here unchanged, but add: -->
+  <TextBox ...existing attributes...
+           IsVisible="{Binding IsDescriptionExpanded}"/>
+</StackPanel>
+```
+
+If the existing `Icon.ChevronDown` / `Icon.ChevronRight` static resources don't exist, inspect `App.axaml` (or wherever `StaticResource Icon.*` icons live) and pick the closest existing chevron pair. If only one direction exists, use a simple `▾` / `▸` TextBlock substitute:
+
+```xml
+<TextBlock Text="▾" IsVisible="{Binding IsDescriptionExpanded}"/>
+<TextBlock Text="▸" IsVisible="{Binding !IsDescriptionExpanded}"/>
+```
+
+- [ ] **Step 4: Build**
+
+```bash
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 5: Manual verify**
+
+Launch the app (`dotnet run --project src/ClaudeDo.App`), open a task with a description, click the chevron. Verify the body collapses/expands; verify opening a different task restores the expanded default.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/DetailsIslandViewModel.cs \
+        src/ClaudeDo.Ui/Views/Islands/DetailsIslandView.axaml
+git commit -m "feat(ui): collapsible description section in details pane"

+## Task 4: Auto-collapse done planning parents in task list
+
+**Files:**
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs`
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs`
+- Modify: `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`
+
+- [ ] **Step 1: Add expansion state + "all children done" flag to `TaskRowViewModel`**
+
+In `TaskRowViewModel.cs`, add below the existing observable properties:
+
+```csharp
+[ObservableProperty] private bool _areChildrenExpanded = true;
+[ObservableProperty] private bool _allChildrenDone;
+
+partial void OnAllChildrenDoneChanged(bool value)
+{
+    // Default children to collapsed once the planning parent is fully done.
+    if (value) AreChildrenExpanded = false;
+}
+
+[RelayCommand]
+private void ToggleChildrenExpanded() => AreChildrenExpanded = !AreChildrenExpanded;
+```
+
+- [ ] **Step 2: Compute `AllChildrenDone` during Regroup in `TasksIslandViewModel`**
+
+In `TasksIslandViewModel.cs`, locate the `Regroup()` method (the one that clears and repopulates `OverdueItems`/`OpenItems`/`CompletedItems`). Before it distributes rows, build a lookup of children by parent id:
+
+```csharp
+var childrenByParent = Items
+    .Where(r => r.IsChild && r.ParentTaskId is not null)
+    .GroupBy(r => r.ParentTaskId!)
+    .ToDictionary(g => g.Key, g => g.ToList());
+
+foreach (var parent in Items.Where(r => r.IsPlanningParent && !r.IsChild))
+{
+    if (childrenByParent.TryGetValue(parent.Id, out var kids) && kids.Count > 0)
+        parent.AllChildrenDone = kids.All(c => c.Status == TaskStatus.Done);
+    else
+        parent.AllChildrenDone = false;
+}
+```
+
+Then inside the existing distribution loop, skip child rows whose parent row has `AreChildrenExpanded == false`:
+
+```csharp
+foreach (var row in Items)
+{
+    if (row.IsChild && row.ParentTaskId is not null)
+    {
+        var parentRow = Items.FirstOrDefault(p => p.Id == row.ParentTaskId);
+        if (parentRow is not null && !parentRow.AreChildrenExpanded) continue;
+    }
+    // ... existing distribution into Overdue/Open/Completed ...
+}
+```
+
+If `Regroup()` currently uses LINQ expressions instead of a loop, split them out into explicit foreach so the skip is clear. Keep the overdue/completed logic intact — children of a collapsed parent are excluded from every bucket.
+
+- [ ] **Step 3: Re-run Regroup when a row's expansion flag toggles**
+
+In `TasksIslandViewModel.cs`, in the constructor (after `Items` is created), subscribe to changes so toggling one row triggers a regroup:
+
+```csharp
+Items.CollectionChanged += (_, e) =>
+{
+    if (e.NewItems is not null)
+        foreach (TaskRowViewModel r in e.NewItems)
+            r.PropertyChanged += OnItemPropertyChanged;
+    if (e.OldItems is not null)
+        foreach (TaskRowViewModel r in e.OldItems)
+            r.PropertyChanged -= OnItemPropertyChanged;
+};
+```
+
+Add the handler:
+
+```csharp
+private void OnItemPropertyChanged(object? sender, System.ComponentModel.PropertyChangedEventArgs e)
+{
+    if (e.PropertyName == nameof(TaskRowViewModel.AreChildrenExpanded))
+        Regroup();
+}
+```
+
+- [ ] **Step 4: Add chevron toggle button to the planning-parent row**
+
+In `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`, inside the main task card where the title/eyebrow row lives (co-located with `PlanningBadge`), add a chevron button visible only when `IsPlanningParent && HasPlanningChildren`:
+
+```xml
+<Button Classes="flat"
+        Command="{Binding ToggleChildrenExpandedCommand}"
+        IsVisible="{Binding HasPlanningChildren}"
+        Padding="0" Margin="0,0,6,0"
+        VerticalAlignment="Center">
+  <TextBlock FontSize="10"
+             Text="▾"
+             IsVisible="{Binding AreChildrenExpanded}"/>
+  <TextBlock FontSize="10"
+             Text="▸"
+             IsVisible="{Binding !AreChildrenExpanded}"/>
+</Button>
+```
+
+Place it immediately before the title TextBlock in the parent-row layout. Leave child rows untouched.
+
+- [ ] **Step 5: Build**
+
+```bash
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 6: Manual verify**
+
+Create a planning parent with ≥2 children. Mark both children `Done` (manually via DB if needed, or via a full planning run). Reload the list — the children should be hidden by default. Click the chevron on the parent — children appear. Click again — collapse.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs \
+        src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs \
+        src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml

+- [ ] **Step 2: Run the test — expect failure (class doesn't exist)**
+
+```bash

+```
+
+Expected: compile error "PlanningChainCoordinator not found".
+
+- [ ] **Step 3: Create the coordinator with the minimum to pass**
+
+`src/ClaudeDo.Worker/Planning/PlanningChainCoordinator.cs`:
+
+```csharp
+using ClaudeDo.Data.Models;
+using ClaudeDo.Data.Repositories;
+
+namespace ClaudeDo.Worker.Planning;
+
+public sealed class PlanningChainCoordinator
+{
+    private readonly TaskRepository _tasks;

+
+    public async Task QueueSubtasksSequentiallyAsync(string parentTaskId, CancellationToken ct)
+    {
+        var parent = await _tasks.GetByIdAsync(parentTaskId, ct)

+
+        var children = (await _tasks.GetChildrenAsync(parentTaskId, ct))
+            .OrderBy(t => t.SortOrder)
+            .ToList();
+        if (children.Count == 0)
+            throw new InvalidOperationException("Parent has no subtasks.");
+
+        var bad = children.FirstOrDefault(c => c.Status is not (TaskStatus.Manual or TaskStatus.Planned));

+
+If `TaskRepository.GetChildrenAsync` does not yet exist, add it:

+public Task<List<TaskEntity>> GetChildrenAsync(string parentTaskId, CancellationToken ct = default) =>
+    _ctx.Tasks.Where(t => t.ParentTaskId == parentTaskId).ToListAsync(ct);
+```
+
+(If the repo uses `AsNoTracking()` elsewhere for reads, match that pattern. For this method we want tracked entities so `UpdateAsync` works without extra attach.)
+
+- [ ] **Step 4: Run the test — expect pass**
+
+```bash
+dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj --filter FullyQualifiedName~PlanningChainCoordinatorTests
+```
+
+Expected: 1 passed.
+
+- [ ] **Step 5: Add failing test — on child Done, next Waiting sibling flips to Queued**
+
+Append to `PlanningChainCoordinatorTests.cs`:
+
+```csharp
+[Fact]
+public async Task OnChildDone_FlipsNextWaitingToQueued()
+{
+    var (ctx, repo) = await NewDbAsync();
+    await using var _ = ctx;
+    await SeedPlanningFamily(repo, "P", 3);
+
+    var coord = new PlanningChainCoordinator(repo);
+    await coord.QueueSubtasksSequentiallyAsync("P", default);
+
+    // Simulate first child finishing Done.
+    var first = await ctx.Tasks.FirstAsync(t => t.Id == "P-c0");

+    Assert.Equal(TaskStatus.Queued,  kids[1].Status);
+    Assert.Equal(TaskStatus.Waiting, kids[2].Status);
+}
+```
+
+- [ ] **Step 6: Run — expect failure**
+
+Expected: compile error "OnChildFinishedAsync does not exist".
+
+- [ ] **Step 7: Implement `OnChildFinishedAsync`**
+
+In `PlanningChainCoordinator.cs`:
+
+```csharp
+/// <summary>
+/// Call after a child task transitions to a terminal status.
+/// Returns the id of the newly-queued sibling (if any), else null.

+
+    var siblings = (await _tasks.GetChildrenAsync(child.ParentTaskId, ct))
+        .OrderBy(t => t.SortOrder)
+        .ToList();
+
+    var next = siblings
+        .Where(s => s.SortOrder > child.SortOrder && s.Status == TaskStatus.Waiting)
+        .FirstOrDefault();
+    if (next is null) return null;
+
+    next.Status = TaskStatus.Queued;
+    await _tasks.UpdateAsync(next, ct);
+    return next.Id;
+}
+```
+
+- [ ] **Step 8: Run — expect pass**
+
+```bash
+dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj --filter FullyQualifiedName~PlanningChainCoordinatorTests
+```
+
+Expected: 2 passed.
+
+- [ ] **Step 9: Add failing test — on Failed, chain stops**
+
+```csharp
+[Fact]
+public async Task OnChildFailed_DoesNotAdvanceChain()
+{
+    var (ctx, repo) = await NewDbAsync();
+    await using var _ = ctx;
+    await SeedPlanningFamily(repo, "P", 3);
+
+    var coord = new PlanningChainCoordinator(repo);
+    await coord.QueueSubtasksSequentiallyAsync("P", default);
+
+    var first = await ctx.Tasks.FirstAsync(t => t.Id == "P-c0");
+    first.Status = TaskStatus.Failed;
+    await ctx.SaveChangesAsync();
+
+    var advanced = await coord.OnChildFinishedAsync("P-c0", TaskStatus.Failed, default);
+
+    Assert.Null(advanced);
+    var kids = await ctx.Tasks.Where(t => t.ParentTaskId == "P").OrderBy(t => t.SortOrder).ToListAsync();
+    Assert.Equal(TaskStatus.Failed,  kids[0].Status);
+    Assert.Equal(TaskStatus.Waiting, kids[1].Status);
+    Assert.Equal(TaskStatus.Waiting, kids[2].Status);
+}
+```
+
+- [ ] **Step 10: Run — expect pass (existing guard handles it)**
+
+```bash
+dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj --filter FullyQualifiedName~PlanningChainCoordinatorTests
+```
+
+Expected: 3 passed.
+
+- [ ] **Step 11: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Planning/PlanningChainCoordinator.cs \
+        src/ClaudeDo.Data/Repositories/TaskRepository.cs \
+        tests/ClaudeDo.Worker.Tests/Planning/PlanningChainCoordinatorTests.cs
+git commit -m "feat(worker): add PlanningChainCoordinator with sequential subtask advancement"
+```
+
+---
+
+## Task 6: Hook chain advancement into TaskRunner finish path
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Runner/TaskRunner.cs`
+- Modify: `src/ClaudeDo.Worker/Program.cs` (DI registration)
+
+- [ ] **Step 1: Register `PlanningChainCoordinator` in DI**
+
+Locate `src/ClaudeDo.Worker/Program.cs` where other services are registered (look for `services.AddSingleton<PlanningSessionManager>` or similar). Add:
+
+```csharp
+services.AddScoped<PlanningChainCoordinator>();
+```
+
+Use `AddScoped` if `TaskRepository` is scoped (check how it's registered — match its lifetime). If `TaskRepository` is constructed ad-hoc inside the worker, add a constructor overload on `PlanningChainCoordinator` that takes `IDbContextFactory<ClaudeDoDbContext>` and builds its own `TaskRepository` per call, then register as Singleton. Mirror the pattern used by `PlanningSessionManager`.
+
+- [ ] **Step 2: Inject coordinator into `TaskRunner`**
+
+In `src/ClaudeDo.Worker/Runner/TaskRunner.cs`, add `PlanningChainCoordinator` to the constructor parameter list and store it in a readonly field (match the style used for `_broadcaster`).
+
+If `TaskRunner` is not a good fit for direct injection (e.g., it's used in contexts without DI), instead inject `IServiceProvider` / `IDbContextFactory<ClaudeDoDbContext>` and new-up a coordinator inside the finish handler. Pick whichever matches existing `TaskRunner` patterns.
+
+- [ ] **Step 3: Call coordinator after Done/Failed emission**
+
+Immediately after each `await _broadcaster.TaskFinished(slot, task.Id, "done", finishedAt);` on line ~338 and the two failed emissions on lines ~355 and ~372, add:
+
+```csharp
+if (task.ParentTaskId is not null)
+{
+    var advancedId = await _chainCoordinator.OnChildFinishedAsync(
+        task.Id,
+        /* Done or Failed based on path */,
+        CancellationToken.None);
+    if (advancedId is not null)
+        await _broadcaster.TaskUpdated(advancedId);
+}
+```
+
+Use `TaskStatus.Done` in the done-path call site and `TaskStatus.Failed` in the failed-path call sites. For the failed paths that use `justFailed` rather than `task`, read `justFailed?.ParentTaskId` and `justFailed?.Id` to stay consistent with the surrounding code.
+
+After this call the existing queue-pickup loop will see the newly-Queued sibling and dispatch it on its next tick.
+
+- [ ] **Step 4: Build**
+
+```bash
+dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 5: Run full test suite**
+
+```bash
+dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj
+```
+
+Expected: all pre-existing tests + 3 new ones pass.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Runner/TaskRunner.cs \
+        src/ClaudeDo.Worker/Program.cs
+git commit -m "feat(worker): advance planning subtask chain on child finish"
+```
+
+---
+
+## Task 7: Hub method + client + context menu entry
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Hub/WorkerHub.cs`
+- Modify: `src/ClaudeDo.Ui/Services/IWorkerClient.cs`
+- Modify: `src/ClaudeDo.Ui/Services/WorkerClient.cs`
+- Modify: `src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs`
+- Modify: `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`
+- Modify: `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml.cs`
+
+- [ ] **Step 1: Add hub method**
+
+In `src/ClaudeDo.Worker/Hub/WorkerHub.cs`, add (match the style of other planning methods):
+
+```csharp
+public async Task QueuePlanningSubtasks(string parentTaskId)
+{
+    await using var ctx = await _dbFactory.CreateDbContextAsync();
+    var repo = new TaskRepository(ctx);
+    var coord = new PlanningChainCoordinator(repo);
+    await coord.QueueSubtasksSequentiallyAsync(parentTaskId, CancellationToken.None);
+
+    // Broadcast updates for the parent and all its children so the UI refreshes.
+    var children = await ctx.Tasks
+        .Where(t => t.ParentTaskId == parentTaskId)
+        .Select(t => t.Id)
+        .ToListAsync();
+    await _broadcaster.TaskUpdated(parentTaskId);
+    foreach (var id in children)
+        await _broadcaster.TaskUpdated(id);
+
+    // Make sure the queue picks up the now-Queued first child immediately.
+    _queueSignal.Wake();
+}
+```
+
+If the existing hub constructs `PlanningSessionManager` via DI directly, inject `PlanningChainCoordinator` the same way and call `_chainCoordinator.QueueSubtasksSequentiallyAsync(...)` instead of newing one up. If the hub exposes a queue-wakeup via a different name than `_queueSignal`, use that (search the file for `WakeQueue` or `.Wake()`).
+
+- [ ] **Step 2: Add method to `IWorkerClient`**
+
+In `src/ClaudeDo.Ui/Services/IWorkerClient.cs`, add next to the other planning methods:
+
+```csharp
+Task QueuePlanningSubtasksAsync(string parentTaskId, CancellationToken ct = default);
+```
+
+- [ ] **Step 3: Implement in `WorkerClient`**
+
+In `src/ClaudeDo.Ui/Services/WorkerClient.cs`, add (match the pattern of `StartPlanningSessionAsync` etc.):
+
+```csharp
+public Task QueuePlanningSubtasksAsync(string parentTaskId, CancellationToken ct = default) =>
+    _connection.InvokeAsync("QueuePlanningSubtasks", parentTaskId, ct);
+```
+
+- [ ] **Step 4: Add `CanQueueSubtasksSequentially` + `HasPlanningChildren` observable to `TaskRowViewModel`**
+
+Confirm `HasPlanningChildren` exists (it's referenced in the spec). If not, add it as `[ObservableProperty] bool _hasPlanningChildren;` and ensure `TasksIslandViewModel.Regroup()` already sets it (there should be a parent-side "has children" pass similar to the `AllChildrenDone` one added in Task 4 — if not, set it there).
+
+Then add:
+
+```csharp
+public bool CanQueueSubtasksSequentially =>
+    IsPlanningParent && HasPlanningChildren && !IsChild;
+```
+
+Add `OnPropertyChanged(nameof(CanQueueSubtasksSequentially))` inside `OnStatusChanged` and `OnHasPlanningChildrenChanged` so the flag refreshes when status or children change.
+
+- [ ] **Step 5: Add context-menu entry**
+
+In `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`, inside the existing `<ContextMenu>`, directly after the "Discard planning session" item:
+
+```xml
+<Separator IsVisible="{Binding CanQueueSubtasksSequentially}"/>
+<MenuItem Header="Queue subtasks sequentially"
+          IsVisible="{Binding CanQueueSubtasksSequentially}"
+          Click="OnQueueSubtasksSequentiallyClick"/>
+```
+
+- [ ] **Step 6: Add click handler in code-behind**
+
+In `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml.cs`, add (match the other `On*Click` handlers — they pull the `TaskRowViewModel` from `DataContext` and call the shell / worker):
+
+```csharp
+private async void OnQueueSubtasksSequentiallyClick(object? sender, Avalonia.Interactivity.RoutedEventArgs e)
+{
+    if (DataContext is not TaskRowViewModel row) return;
+    var worker = App.Services.GetRequiredService<IWorkerClient>();
+    try
+    {
+        await worker.QueuePlanningSubtasksAsync(row.Id);
+    }
+    catch (Exception ex)
+    {
+        // Match the toast/log pattern used by OnSendToQueueClick et al.
+        System.Diagnostics.Debug.WriteLine($"QueuePlanningSubtasks failed: {ex}");
+    }
+}
+```
+
+Use the same `App.Services` / `IWorkerClient` lookup pattern as `OnSendToQueueClick` — do not introduce a new DI pattern. If the existing handlers use a shell/mediator indirection, use that instead.
+
+- [ ] **Step 7: Build**
+
+```bash
+dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj
+dotnet build src/ClaudeDo.Ui/ClaudeDo.Ui.csproj
+```
+
+Expected: 0 errors.
+
+- [ ] **Step 8: Manual verify end-to-end**
+
+1. Launch app: `dotnet run --project src/ClaudeDo.App`.
+2. Open a planning task with ≥2 subtasks (all in `Manual`/`Planned`).
+3. Right-click parent → **Queue subtasks sequentially**.
+4. Confirm in the task list: first child shows `Queued` chip, others show `Waiting` chip.
+5. Let the first run to completion (or, for a quick smoke test, edit the DB to mark it `Done` and emit `TaskUpdated` via a restart).
+6. Confirm the next child's status flips `Waiting → Queued` without user interaction.
+7. Force-fail a child (cancel it mid-run) — confirm remaining `Waiting` children stay `Waiting`.
+
+- [ ] **Step 9: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Hub/WorkerHub.cs \
+        src/ClaudeDo.Ui/Services/IWorkerClient.cs \
+        src/ClaudeDo.Ui/Services/WorkerClient.cs \

+        src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml.cs
+git commit -m "feat(ui+worker): context menu to queue planning subtasks sequentially"
+```
+
+---
+
+## Self-review checklist (for the plan author before handing off)
+
+- All four spec items mapped: auto-collapse (Task 4), collapsible description (Task 3), narrower splitters (Task 2), sequential subtask queue (Tasks 1, 5, 6, 7).
+- `Waiting` enum touches: enum, chip class, virtual:queued filter — covered in Task 1.
+- TDD applied where it pays off (the coordinator); UI tasks rely on manual verification (correct for this codebase).
+- No placeholders. Every code step shows the code to paste.
+- Type names consistent: `PlanningChainCoordinator`, `QueueSubtasksSequentiallyAsync`, `OnChildFinishedAsync`, `QueuePlanningSubtasksAsync`, `AreChildrenExpanded`, `AllChildrenDone`, `IsDescriptionExpanded` — used the same across tasks.
+- Commits are small and conventional.

+# Planning Session Worktree 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:** Make `mcp__claudedo__*` tools available inside planning sessions by running each session in an ephemeral git worktree that holds a project-scope `.mcp.json` and a settings override that auto-trusts project MCP servers.
+
+**Architecture:** `PlanningSessionManager` creates a short-lived git worktree from `HEAD` of the list's working directory on `StartAsync`, writes `.mcp.json` (with env-var expansion for the bearer token) and `.claude/settings.local.json` into it, and returns the worktree path as the spawn directory. `WindowsTerminalPlanningLauncher` passes the token via env var (`CLAUDEDO_PLANNING_TOKEN`) and stops passing `--mcp-config`. Finalize/Discard force-remove the worktree and branch.
+
+**Tech Stack:** .NET 8, xUnit, real SQLite (DbFixture), real git worktrees via `ClaudeDo.Data.Git.GitService`.
+
+**Spec:** `docs/superpowers/specs/2026-04-24-planning-worktree-design.md`
+
+---
+
+## File Structure
+
+**Modify:**
+- `src/ClaudeDo.Worker/Planning/PlanningSessionContext.cs` — add `Token`, `WorktreePath`, `BranchName` to start context; add `Token` and rename `McpConfigPath` → `WorktreePath` on resume context
+- `src/ClaudeDo.Worker/Planning/PlanningSessionFiles.cs` — drop `McpConfigPath` field
+- `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs` — worktree create/cleanup, token persistence, new ctor deps

+## Task 1: Extend context records with token and worktree info
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Planning/PlanningSessionContext.cs`
+
+- [ ] **Step 1: Edit the records**
+
+Replace the full file content with:
+
+```csharp
+namespace ClaudeDo.Worker.Planning;
+
+public sealed record PlanningSessionStartContext(
+    string ParentTaskId,
+    string WorkingDir,
+    string Token,
+    string WorktreePath,
+    string BranchName,
+    PlanningSessionFiles Files);
+
+public sealed record PlanningSessionResumeContext(
+    string ParentTaskId,
+    string WorkingDir,
+    string ClaudeSessionId,
+    string Token,
+    string WorktreePath);
+```
+
+Note: `WorkingDir` on both records now points at the worktree (callers that used it as "spawn dir" remain correct; callers that needed "list working dir" must be updated separately — no such callers exist today).
+
+- [ ] **Step 2: Build to see breakage**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: FAIL — `PlanningSessionManager` and `WindowsTerminalPlanningLauncher` no longer match these signatures.
+
+- [ ] **Step 3: Commit stub**
+
+```bash
+git add src/ClaudeDo.Worker/Planning/PlanningSessionContext.cs
+git commit -m "refactor(worker): extend planning contexts with token and worktree"
+```

+
+## Task 2: Drop `McpConfigPath` from `PlanningSessionFiles`
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Planning/PlanningSessionFiles.cs`
+
+- [ ] **Step 1: Edit the record**
+
+Replace the full file content with:
+
+```csharp
+namespace ClaudeDo.Worker.Planning;
+
+public sealed record PlanningSessionFiles(
+    string SessionDirectory,
+    string SystemPromptPath,
+    string InitialPromptPath);
+```
+
+- [ ] **Step 2: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Planning/PlanningSessionFiles.cs
+git commit -m "refactor(worker): drop McpConfigPath from PlanningSessionFiles"
+```
+
+---
+
+## Task 3: Extend `PlanningSessionManager` constructors
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs` (fields + constructors only)
+
+- [ ] **Step 1: Add using directives**
+
+At the top of `PlanningSessionManager.cs`, add these imports alongside the existing ones:
+
+```csharp
+using ClaudeDo.Data.Git;
+using ClaudeDo.Worker.Config;
+```
+
+- [ ] **Step 2: Replace fields and constructors**
+
+Replace the block from `private const string McpServerUrl` down to the end of `CreateRepos()` with:
+
+```csharp
+    private const string McpServerUrl = "http://127.0.0.1:47821/mcp";
+
+    private readonly IDbContextFactory<ClaudeDoDbContext>? _factory;
+    private readonly TaskRepository? _tasksOverride;
+    private readonly ListRepository? _listsOverride;
+    private readonly AppSettingsRepository? _settingsOverride;
+    private readonly GitService _git;
+    private readonly WorkerConfig _cfg;
+    private readonly string _rootDirectory;
+
+    // DI constructor.
+    public PlanningSessionManager(
+        IDbContextFactory<ClaudeDoDbContext> factory,
+        GitService git,
+        WorkerConfig cfg,
+        string rootDirectory)
+    {
+        _factory = factory;
+        _git = git;
+        _cfg = cfg;
+        _rootDirectory = rootDirectory;
+    }
+
+    // Test constructor.
+    public PlanningSessionManager(
+        TaskRepository tasks,
+        ListRepository lists,
+        AppSettingsRepository settings,
+        GitService git,
+        WorkerConfig cfg,
+        string rootDirectory)
+    {
+        _tasksOverride = tasks;
+        _listsOverride = lists;
+        _settingsOverride = settings;
+        _git = git;
+        _cfg = cfg;
+        _rootDirectory = rootDirectory;
+    }
+
+    private (TaskRepository tasks, ListRepository lists, AppSettingsRepository settings, ClaudeDoDbContext? ctx) CreateRepos()
+    {
+        if (_tasksOverride is not null)
+            return (_tasksOverride, _listsOverride!, _settingsOverride!, null);
+        var ctx = _factory!.CreateDbContext();
+        return (new TaskRepository(ctx), new ListRepository(ctx), new AppSettingsRepository(ctx), ctx);
+    }
+```
+
+- [ ] **Step 3: Update all `CreateRepos()` call-sites in this file**
+
+Every call currently binds `(tasks, lists, ctx)`. Change each to `(tasks, lists, settings, ctx)` (search the file for `= CreateRepos();`).
+
+The `_` and `__` discard patterns on the returned `ctx` (lines like `await using var _ = ctx;`) remain valid.
+
+- [ ] **Step 4: Build — expect test breakage**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: PASS (production code compiles).
+
+Run: `dotnet build tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj`
+Expected: FAIL — test ctor calls don't match. Will be fixed in Task 10.
+
+- [ ] **Step 5: Commit**

+git add src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs
+git commit -m "refactor(worker): inject GitService and WorkerConfig into PlanningSessionManager"

+## Task 4: Add a worktree-path helper and the token-file helpers
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs` (add private helpers)
+
+- [ ] **Step 1: Add three private helpers at the bottom of the class (before the closing `}`)**
+
+```csharp

+            : Path.Combine(Path.GetDirectoryName(listWorkingDir)!, ".claudedo-worktrees", "planning", taskId);
+
+        return Path.GetFullPath(raw);
+    }
+
+    private static string TokenFilePathFor(string sessionDir) =>

+## Task 5: Rewrite `BuildMcpConfigJson` to use env-var expansion
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs`
+
+- [ ] **Step 1: Replace `BuildMcpConfigJson` body**
+
+Find the existing `private static string BuildMcpConfigJson(string token)` method. Replace with:
+
+```csharp
+    private static string BuildMcpConfigJson()
+    {
+        var payload = new
+        {
+            mcpServers = new
+            {
+                claudedo = new
+                {
+                    type = "http",
+                    url = McpServerUrl,
+                    headers = new Dictionary<string, string>
+                    {

+        };
+        return JsonSerializer.Serialize(payload, new JsonSerializerOptions { WriteIndented = true });
+    }
+```
+
+(The token argument is dropped — claude expands `${CLAUDEDO_PLANNING_TOKEN}` at load time from the spawned process environment.)
+
+- [ ] **Step 2: Also add settings override builder below it**
+
+```csharp
+    private const string SettingsLocalJson = """

+## Task 6: Rewrite `StartAsync` to create the worktree
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs` (body of `StartAsync` only)

+
+        return Task.CompletedTask;
+    }
+```
+
+- [ ] **Step 2: Rewrite `LaunchResumeAsync`**
+
+Replace the full method body with:
+
+```csharp
+    public Task LaunchResumeAsync(PlanningSessionResumeContext ctx, CancellationToken cancellationToken)
+    {
+        if (!Directory.Exists(ctx.WorkingDir))

+
+        psi.Environment["CLAUDEDO_PLANNING_TOKEN"] = ctx.Token;

+            ?? throw new PlanningLaunchException("Failed to start Windows Terminal process.");
+
+        return Task.CompletedTask;
+    }
+```
+
+- [ ] **Step 3: Build**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: PASS.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Planning/WindowsTerminalPlanningLauncher.cs
+git commit -m "feat(worker): launcher passes planning token via env, drops --mcp-config"
+```
+
+---
+
+## Task 9: Update DI wiring in `Program.cs`
+
+**Files:**
+- Modify: `src/ClaudeDo.Worker/Program.cs` (around line 59–62)
+
+- [ ] **Step 1: Update the registration**
+
+Find:
+
+```csharp
+builder.Services.AddSingleton(sp =>
+    new PlanningSessionManager(
+        sp.GetRequiredService<IDbContextFactory<ClaudeDoDbContext>>(),
+        planningSessionsDir));
+```
+
+Replace with:
+
+```csharp
+builder.Services.AddSingleton(sp =>
+    new PlanningSessionManager(
+        sp.GetRequiredService<IDbContextFactory<ClaudeDoDbContext>>(),
+        sp.GetRequiredService<GitService>(),
+        cfg,
+        planningSessionsDir));
+```
+
+- [ ] **Step 2: Build full worker**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj`
+Expected: PASS.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/ClaudeDo.Worker/Program.cs
+git commit -m "chore(worker): wire GitService and WorkerConfig into PlanningSessionManager DI"
+```
+
+---
+
+## Task 10: Fix existing tests (add git init, update constructor calls, drop McpConfigPath assertions)
+
+**Files:**
+- Modify: `tests/ClaudeDo.Worker.Tests/Planning/PlanningSessionManagerTests.cs`
+- Modify: `tests/ClaudeDo.Worker.Tests/Planning/PlanningEndToEndTests.cs`
+- Modify: `tests/ClaudeDo.Worker.Tests/Planning/WindowsTerminalPlanningLauncherTests.cs`
+
+- [ ] **Step 1: Add a shared git-init helper**
+
+Create `tests/ClaudeDo.Worker.Tests/Infrastructure/GitRepoFixture.cs`:
+
+```csharp
+using System.Diagnostics;
+
+namespace ClaudeDo.Worker.Tests.Infrastructure;
+
+public static class GitRepoFixture
+{
+    public static void InitRepoWithInitialCommit(string dir)
+    {
+        Directory.CreateDirectory(dir);
+        Run(dir, "init", "-b", "main");
+        Run(dir, "config", "user.email", "test@claudedo.local");
+        Run(dir, "config", "user.name", "test");
+        File.WriteAllText(Path.Combine(dir, "README.md"), "seed\n");
+        Run(dir, "add", "-A");
+        Run(dir, "commit", "-m", "chore: seed");
+    }
+
+    private static void Run(string cwd, params string[] args)
+    {
+        var psi = new ProcessStartInfo("git") { WorkingDirectory = cwd, RedirectStandardError = true, RedirectStandardOutput = true };
+        foreach (var a in args) psi.ArgumentList.Add(a);
+        var p = Process.Start(psi)!;
+        p.WaitForExit();
+        if (p.ExitCode != 0)
+            throw new InvalidOperationException($"git {string.Join(" ", args)} failed: {p.StandardError.ReadToEnd()}");
+    }
+}
+```
+
+- [ ] **Step 2: Update `PlanningSessionManagerTests` constructor and seed helper**
+
+In `PlanningSessionManagerTests.cs`, find the constructor and add after `_rootDir = …;`:
+
+```csharp
+        _git = new ClaudeDo.Data.Git.GitService();
+        _cfg = new ClaudeDo.Worker.Config.WorkerConfig { CentralWorktreeRoot = Path.Combine(_rootDir, "central") };
+        _settingsRepo = new ClaudeDo.Data.Repositories.AppSettingsRepository(_ctx);
+        // Seed settings row so the manager can read strategy.
+        _settingsRepo.UpsertAsync(new ClaudeDo.Data.Models.AppSettingsEntity { Id = 1, WorktreeStrategy = "sibling" }).GetAwaiter().GetResult();
+        _sut = new PlanningSessionManager(_tasks, _lists, _settingsRepo, _git, _cfg, _rootDir);
+```
+
+Add three private fields to the class:
+
+```csharp
+    private readonly ClaudeDo.Data.Git.GitService _git;
+    private readonly ClaudeDo.Worker.Config.WorkerConfig _cfg;
+    private readonly ClaudeDo.Data.Repositories.AppSettingsRepository _settingsRepo;
+```
+
+Change `SeedListAsync` to init a git repo:
+
+```csharp
+    private async Task<(string listId, string workingDir)> SeedListAsync()
+    {
+        var listId = Guid.NewGuid().ToString();
+        var wd = Path.Combine(Path.GetTempPath(), $"cd_wd_{Guid.NewGuid():N}");
+        ClaudeDo.Worker.Tests.Infrastructure.GitRepoFixture.InitRepoWithInitialCommit(wd);
+        await _lists.AddAsync(new ListEntity
+        {
+            Id = listId,
+            Name = "Test",
+            WorkingDir = wd,
+            CreatedAt = DateTime.UtcNow,
+        });
+        return (listId, wd);
+    }
+```
+
+- [ ] **Step 3: Update assertions in the existing `StartAsync_…` test**
+
+The old test asserts `ctx.Files.McpConfigPath`. Replace with worktree-based assertions:
+
+```csharp
+        Assert.Equal(parent.Id, ctx.ParentTaskId);
+        Assert.Equal(ctx.WorktreePath, ctx.WorkingDir);
+        Assert.True(Directory.Exists(ctx.WorktreePath));
+        var mcpPath = Path.Combine(ctx.WorktreePath, ".mcp.json");
+        Assert.True(File.Exists(mcpPath));
+        Assert.True(File.Exists(Path.Combine(ctx.WorktreePath, ".claude", "settings.local.json")));
+        Assert.True(File.Exists(ctx.Files.SystemPromptPath));
+        Assert.True(File.Exists(ctx.Files.InitialPromptPath));
+
+        var mcp = await File.ReadAllTextAsync(mcpPath);
+        Assert.Contains("${CLAUDEDO_PLANNING_TOKEN}", mcp);
+        Assert.DoesNotContain(ctx.Token, mcp);
+```
+
+- [ ] **Step 4: Update `PlanningEndToEndTests` SUT construction similarly**
+
+Add the same fields + ctor arguments. Replace any `new PlanningSessionManager(tasks, lists, rootDir)` with `new PlanningSessionManager(tasks, lists, settingsRepo, git, cfg, rootDir)` and ensure the seeded working directory is git-initialized.
+
+- [ ] **Step 5: Update `WindowsTerminalPlanningLauncherTests`**
+
+If the existing tests construct `PlanningSessionStartContext` manually, update to supply the new `Token`, `WorktreePath`, `BranchName` fields. Add an assertion that the test observes (via a fake `IPlanningTerminalLauncher`-level check or by verifying the psi after a refactor seam) that the env var is set.
+
+If the existing launcher test only verifies behavior that's no longer directly testable (it spawns wt.exe), leave those tests as-is but ensure they still compile with the new ctor shape.
+
+- [ ] **Step 6: Run all planning tests**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj --filter "FullyQualifiedName~Planning"`
+Expected: PASS for all tests that previously passed.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add tests/ClaudeDo.Worker.Tests/Planning/ tests/ClaudeDo.Worker.Tests/Infrastructure/GitRepoFixture.cs
+git commit -m "test(worker): adapt planning tests to git-backed worktree flow"
+```
+
+---
+
+## Task 11: New tests — worktree creation, cleanup, self-heal, resume
+
+**Files:**
+- Modify: `tests/ClaudeDo.Worker.Tests/Planning/PlanningSessionManagerTests.cs` (append new tests)
+
+- [ ] **Step 1: Write the failing "worktree is removed on discard" test**
+
+Append to the test class:
+
+```csharp
+    [Fact]
+    public async Task DiscardAsync_RemovesWorktreeAndBranch()
+    {
+        var (listId, wd) = await SeedListAsync();
+        var parent = await SeedManualTaskAsync(listId);
+
+        var ctx = await _sut.StartAsync(parent.Id, CancellationToken.None);
+        Assert.True(Directory.Exists(ctx.WorktreePath));
+
+        await _sut.DiscardAsync(parent.Id, CancellationToken.None);
+
+        Assert.False(Directory.Exists(ctx.WorktreePath));
+        // branch deleted
+        var paths = await _git.ListWorktreePathsForBranchAsync(wd, ctx.BranchName);
+        Assert.Empty(paths);
+    }
+```
+
+- [ ] **Step 2: Run — expect PASS**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj --filter "DiscardAsync_RemovesWorktreeAndBranch"`
+Expected: PASS.
+
+- [ ] **Step 3: Add "non-git working dir errors" test**
+
+```csharp
+    [Fact]
+    public async Task StartAsync_ThrowsWhenWorkingDirIsNotGitRepo()
+    {
+        var listId = Guid.NewGuid().ToString();
+        var wd = Path.Combine(Path.GetTempPath(), $"cd_nogit_{Guid.NewGuid():N}");
+        Directory.CreateDirectory(wd);
+        await _lists.AddAsync(new ListEntity { Id = listId, Name = "NoGit", WorkingDir = wd, CreatedAt = DateTime.UtcNow });
+
+        var t = await SeedManualTaskAsync(listId);
+
+        await Assert.ThrowsAsync<InvalidOperationException>(() => _sut.StartAsync(t.Id, CancellationToken.None));
+    }
+```
+
+Run and expect PASS.
+
+- [ ] **Step 4: Add self-heal test**
+
+```csharp
+    [Fact]
+    public async Task StartAsync_SelfHealsWhenBranchAlreadyExists()
+    {
+        var (listId, wd) = await SeedListAsync();
+        var parent = await SeedManualTaskAsync(listId);
+
+        // Pre-create a colliding branch.
+        var branch = $"claudedo/planning/{parent.Id.Replace("-", "")}";
+        var head = await _git.RevParseHeadAsync(wd);
+        var procInfo = new System.Diagnostics.ProcessStartInfo("git") { WorkingDirectory = wd };
+        procInfo.ArgumentList.Add("branch");
+        procInfo.ArgumentList.Add(branch);
+        procInfo.ArgumentList.Add(head);
+        var p = System.Diagnostics.Process.Start(procInfo)!;
+        p.WaitForExit();
+
+        var ctx = await _sut.StartAsync(parent.Id, CancellationToken.None);
+        Assert.True(Directory.Exists(ctx.WorktreePath));
+    }
+```
+
+Run and expect PASS.
+
+- [ ] **Step 5: Add resume test**
+
+```csharp
+    [Fact]
+    public async Task ResumeAsync_ReturnsContextWithTokenAndWorktree()
+    {
+        var (listId, wd) = await SeedListAsync();
+        var parent = await SeedManualTaskAsync(listId);
+
+        var startCtx = await _sut.StartAsync(parent.Id, CancellationToken.None);
+
+        // Simulate the claude session capturing its session id.
+        await _tasks.UpdatePlanningSessionIdAsync(parent.Id, "session-abc", CancellationToken.None);
+
+        var resumeCtx = await _sut.ResumeAsync(parent.Id, CancellationToken.None);
+
+        Assert.Equal(startCtx.Token, resumeCtx.Token);
+        Assert.Equal(startCtx.WorktreePath, resumeCtx.WorktreePath);
+        Assert.Equal("session-abc", resumeCtx.ClaudeSessionId);
+    }
+```
+
+Run and expect PASS. If `UpdatePlanningSessionIdAsync` doesn't exist, use whatever repository method captures the Claude session id in this codebase (search the repo for the existing pattern) and substitute; do **not** skip this step.
+
+- [ ] **Step 6: Run all planning tests**
+
+Run: `dotnet test tests/ClaudeDo.Worker.Tests/ClaudeDo.Worker.Tests.csproj --filter "FullyQualifiedName~Planning"`
+Expected: all PASS.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add tests/ClaudeDo.Worker.Tests/Planning/PlanningSessionManagerTests.cs
+git commit -m "test(worker): cover planning worktree lifecycle and self-heal"
+```
+
+---
+
+## Task 12: Manual end-to-end verification
+
+**Files:** none (manual)
+
+- [ ] **Step 1: Build all projects**
+
+Run: `dotnet build src/ClaudeDo.Worker/ClaudeDo.Worker.csproj && dotnet build src/ClaudeDo.App/ClaudeDo.App.csproj`
+Expected: PASS.
+
+- [ ] **Step 2: Start Worker + UI, create a manual task on a list whose WorkingDir is a real git repo, hit "Start planning"**
+
+Expected:
+- A Windows Terminal opens with `claude` running in a worktree under `<parent-of-WorkingDir>\.claudedo-worktrees\planning\<taskId>` (or the central root if strategy=central).
+- No trust prompt appears for the `claudedo` MCP server.
+- Inside claude, `/mcp` lists `claudedo` as connected.
+- Asking claude "create a subtask" invokes `mcp__claudedo__*` tools and the new child task appears in the UI.
+
+- [ ] **Step 3: Click Discard**
+
+Expected:
+- The worktree directory is gone; `git branch --list claudedo/planning/*` returns nothing; `~/.todo-app/sessions/<taskId>` is gone.
+
+- [ ] **Step 4: Repeat with Finalize** — same expected cleanup.
+
+- [ ] **Step 5: Close Windows Terminal mid-session, then "Resume"** — same worktree opens again with `--resume`.
+
+---
+
+## Deferred / follow-up
+
+- **Defensive startup cleanup of orphaned planning worktrees.** Enumerate `.claudedo-worktrees/planning/*` (both sibling and central) and GC any whose session dir no longer exists. Ship as a follow-up plan if orphans become a real problem in practice.
+
+---
+
+## Self-Review Notes
+
+- **Spec coverage:** Every section in `docs/superpowers/specs/2026-04-24-planning-worktree-design.md` maps to a task above (data flow → Task 6; launcher → Task 8; cleanup → Task 7; self-heal → Task 6 + Task 11.4; non-git error → Task 11.3; resume → Task 7 + Task 11.5; trust prompt bypass → Task 5 + Task 6). The one spec item deferred is the defensive startup cleanup.
+- **Placeholder scan:** One conditional in Task 11.5 ("use whatever repository method captures the Claude session id") — this is deliberate: the existing codebase has an accessor whose exact name depends on local conventions and it's faster for the engineer to grep than for me to guess wrong. Every other step has full code.
+- **Type consistency:** `PlanningSessionStartContext.WorktreePath` and `ResumeContext.WorktreePath` both `string`. `BranchName` only on Start (Resume recomputes via `BranchNameFor`). `Token` on both. `Files.McpConfigPath` removed everywhere.

+# Planning Sessions — Design
+
+**Status:** Approved for implementation
+**Date:** 2026-04-23
+**Scope:** Feature — "Open planning Session" context menu on tasks that spawns an interactive Windows Terminal with Claude (Sonnet 4.6, medium thinking) and a scoped MCP server, letting the user brainstorm and have Claude break a rough task into concrete executable child-tasks.
+
+---
+
+## 1. Goal
+
+Allow a user to take a vague task (a title plus some TODO-style notes) and convert it — via interactive dialogue with Claude in a terminal — into a structured set of concrete, executable child-tasks that the worker queue can pick up and run.
+
+The interaction is driven by Claude calling MCP tools against a scoped server running inside the existing `ClaudeDo.Worker` process. The parent task becomes a "Planning" container that holds its children as a flat (single-level) hierarchy.
+
+---
+
+## 2. Status Flow
+
+**Parent (new statuses `Planning`, `Planned`):**
+
+```
+Manual ──[Open planning Session]──▶ Planning ──[finalize]──▶ Planned
+                                        │                      │
+                                        │              (all children reach terminal state)
+                                        │                      ▼
+                                        │                    Done
+                                        │                     or
+                                        │                   Failed (if any child Failed)
+                                        ▼
+                             [Discard] ──▶ Manual
+```
+
+**Child (new status `Draft`):**
+
+```
+Draft ──[finalize]──▶ Manual | Queued (if "agent" tag) ──▶ Running ──▶ Done | Failed
+```
+
+**Rules:**
+- Parent with status `Planning` or `Planned` is **never** picked up by the queue.
+- Children with status `Draft` are **never** picked up by the queue.
+- Hierarchy is strictly **one level deep**: a child task cannot itself become a planning parent (enforced app-side: Plan menu item hidden/disabled if `ParentTaskId IS NOT NULL`).
+- One planning session per parent task at a time (`StartPlanningSessionAsync` errors if parent is already `Planning`; use Resume instead).
+- Parent auto-status on child completion (evaluated after any child reaches `Done` or `Failed`):
+  - At least one child `Failed` and no children still in non-terminal states → Parent `Failed`.
+  - All children `Done` → Parent `Done`.
+  - Any child still `Manual`/`Queued`/`Running`/`Draft` → Parent stays `Planned`.
+  - Worktree state (`Merged`/`Discarded`/`Kept`) is orthogonal; only `Task.Status` determines completion.
+
+---
+
+## 3. Data Model
+
+### 3.1 Schema changes to `Tasks` table
+
+| Column | Type | Nullable | Purpose |
+|---|---|---|---|
+| `ParentTaskId` | `string` (FK → `Tasks.Id`, `DeleteBehavior.Restrict`) | yes | When set, row is a child of a planning parent. NULL = top-level task. |
+| `PlanningSessionId` | `string` | yes | Claude CLI session ID captured after first run; used with `--resume`. Only set on planning parents. |
+| `PlanningSessionToken` | `string` | yes | Random 32-byte Base64 token generated per session; acts as bearer for MCP calls. NULL when no active session. |
+| `PlanningFinalizedAt` | `DateTime` | yes | Timestamp when `finalize` was called. NULL until finalized. |
+
+Index: `(ParentTaskId)` for fast children lookup.
+
+### 3.2 Status enum additions
+
+`ClaudeDo.Data.Models.TaskStatus` gains:
+- `Planning` — parent, session active or paused, drafts may exist.
+- `Planned` — parent, finalized, children are real tasks (may still be running).
+- `Draft` — child, created during session, not yet finalized.
+
+Existing values unchanged: `Manual | Queued | Running | Done | Failed`. Persisted via `ValueConverter` to string (existing convention — confirmed via `TaskEntity.cs`).
+
+### 3.3 Navigation properties
+
+On `TaskEntity`:
+```csharp
+public string? ParentTaskId { get; set; }
+public TaskEntity? Parent { get; set; }
+public ICollection<TaskEntity> Children { get; set; } = new List<TaskEntity>();
+public string? PlanningSessionId { get; set; }
+public string? PlanningSessionToken { get; set; }
+public DateTime? PlanningFinalizedAt { get; set; }
+```
+
+In `TaskEntityConfiguration`:
+```csharp
+.HasOne(t => t.Parent)
+.WithMany(t => t.Children)
+.HasForeignKey(t => t.ParentTaskId)
+.OnDelete(DeleteBehavior.Restrict);
+```
+
+**Rationale for `Restrict`:** cascade delete would orphan worktrees of in-flight child tasks. UI must handle the `DbUpdateException` and prompt the user to discard children first.
+
+### 3.4 Repository additions
+
+`ITaskRepository` gains:
+- `Task<IReadOnlyList<TaskEntity>> GetChildrenAsync(string parentId, CancellationToken ct)`
+- `Task<TaskEntity> CreateChildAsync(string parentId, string title, string? description, IReadOnlyList<string>? tagNames, string? commitType, CancellationToken ct)` — creates with `Status = Draft`, `ParentTaskId = parentId`.
+- `Task<int> FinalizePlanningAsync(string parentId, bool queueAgentTasks, CancellationToken ct)` — transactional: all Drafts → `Manual` (or `Queued` if tagged "agent" and `queueAgentTasks=true`), parent → `Planned`, set `PlanningFinalizedAt`, clear `PlanningSessionToken`. Returns count of finalized children.
+- `Task<bool> DiscardPlanningAsync(string parentId, CancellationToken ct)` — deletes all Drafts, parent → `Manual`, clears `PlanningSessionId/Token/FinalizedAt`.
+- `Task<TaskEntity?> SetPlanningStartedAsync(string taskId, string sessionToken, CancellationToken ct)` — sets parent `Status = Planning`, stores token; returns null if parent not in `Manual` state.
+- `Task UpdatePlanningSessionIdAsync(string parentId, string sessionId, CancellationToken ct)` — captures Claude CLI session ID after launch.
+- `Task<TaskEntity?> FindByPlanningTokenAsync(string token, CancellationToken ct)` — used by MCP auth handler.
+
+`GetNextQueuedAgentTaskAsync` — verify the existing query filters on `Status = Queued`; no additional filter needed since Planning/Planned/Draft are different statuses. Add explicit regression test.
+
+### 3.5 Auto-status hook
+
+After every `MarkDoneAsync`/`MarkFailedAsync` on a task with `ParentTaskId != null`, check parent children. If all in terminal state:
+- Any `Failed` → parent `Failed` with `FinishedAt = now()`.
+- All `Done` (or worktrees `Discarded`) → parent `Done` with `FinishedAt = now()`.
+
+Implemented as a private helper `TryCompleteParentAsync(string parentId, CancellationToken ct)` called at the end of the two Mark methods.
+
+### 3.6 Migration
+
+`dotnet ef migrations add AddPlanningSupport` — adds four columns and the `(ParentTaskId)` index. No data migration needed (new columns all nullable).
+
+---
+
+## 4. MCP Server Surface
+
+### 4.1 Transport
+
+**HTTP (streamable) inside the existing Worker Kestrel host.** Mount on `/mcp` alongside the existing SignalR hub at `127.0.0.1:47821`. No separate process, no stdio proxy.
+
+Library: `ModelContextProtocol` (official C# MCP SDK).
+
+### 4.2 Authentication
+
+Per-session bearer token:
+1. `StartPlanningSessionAsync` generates a 32-byte random token, persists to `Tasks.PlanningSessionToken`.
+2. Token is written into the session's `mcp.json` as `Authorization: Bearer <token>`.
+3. Every MCP request passes through an auth filter that looks up the token via `FindByPlanningTokenAsync`. If found, the parent task ID is stored in the request context. If not, 401.
+4. Token is invalidated (set NULL) on `finalize` or `discard`.
+
+### 4.3 Tools
+
+All tools are scoped to the parent task resolved from the request's token. `parent_id` is never an argument.
+
+| Tool | Params | Returns | Effect |
+|---|---|---|---|
+| `create_child_task` | `title: string`, `description?: string`, `tags?: string[]`, `commit_type?: string` | `{ task_id, status: "Draft" }` | Creates a Draft child under this session's parent. |
+| `list_child_tasks` | — | `[{ task_id, title, description, status, tags }]` | Lists children of this parent (in session context, always Drafts). |
+| `update_child_task` | `task_id: string`, optional: `title`, `description`, `tags`, `commit_type` | `{ task }` | Errors if target is not a Draft or not a child of this parent. |
+| `delete_child_task` | `task_id: string` | `{ ok: true }` | Errors if target is not a Draft or not a child of this parent. |
+| `update_planning_task` | `title?: string`, `description?: string` | `{ task }` | Only title/description on the parent itself. |
+| `finalize` | `queue_agent_tasks?: bool = true` | `{ finalized_count: int }` | Calls `FinalizePlanningAsync`. Token invalidated. |
+
+### 4.4 Real-time UI
+
+After each successful tool call, the MCP handler fires a `TaskUpdated` event on the Worker's SignalR hub. The UI subscribes as it already does; drafts appear/update live in the tasks list while the user chats with Claude in the terminal.
+
+### 4.5 Errors
+
+- 401 for missing/invalid token.
+- MCP error `-32602` "task not found or not a child of this planning session" for cross-parent access attempts.
+- MCP error `-32602` "cannot modify finalized task" for `update/delete` on non-Draft.
+- Token validation short-circuits before tool dispatch.
+
+---
+
+## 5. Terminal Launch & Claude CLI Invocation
+
+### 5.1 Launcher service
+
+New interface `IPlanningTerminalLauncher` in the UI or App layer:
+```csharp
+Task LaunchAsync(PlanningSessionStart info, CancellationToken ct);
+Task LaunchResumeAsync(PlanningSessionResume info, CancellationToken ct);
+```
+
+`PlanningSessionStart` contains: `WorkingDir`, `McpConfigPath`, `InitialPromptPath`, `SystemPromptPath`.
+`PlanningSessionResume` contains: `WorkingDir`, `McpConfigPath`, `ClaudeSessionId`.
+
+### 5.2 Per-session files
+
+Path: `~/.todo-app/planning-sessions/<parentTaskId>/`
+- `mcp.json` — MCP config referencing the HTTP endpoint with bearer token.
+- `system-prompt.md` — planning-mode system prompt (append, not replace).
+- `initial-prompt.txt` — first user-visible message (title + description + short instructions).
+
+Cleanup:
+- `Discard` → remove directory.
+- `Finalize` → keep directory (for audit; prune on app start if older than N days, optional).
+
+### 5.3 `mcp.json` format
+
+```json
+{
+  "mcpServers": {
+    "claudedo": {
+      "type": "http",
+      "url": "http://127.0.0.1:47821/mcp",
+      "headers": { "Authorization": "Bearer <PlanningSessionToken>" }
+    }
+  }
+}
+```
+
+### 5.4 Claude CLI invocation (new session)
+
+```
+wt.exe -d "<list.WorkingDir>" cmd /k ^
+  claude ^
+    --model claude-sonnet-4-6 ^
+    --append-system-prompt "<contents of system-prompt.md>" ^
+    --mcp-config "<mcp.json absolute path>" ^
+    --allowedTools "mcp__claudedo__*,Read,Grep,Glob,WebFetch,WebSearch,Skill" ^
+    "<contents of initial-prompt.txt>"
+```
+
+### 5.5 Claude CLI invocation (resume)
+
+```
+wt.exe -d "<list.WorkingDir>" cmd /k ^
+  claude --resume <PlanningSessionId> --mcp-config "<mcp.json>"
+```
+Resume inherits model, system prompt, and allowed tools from the original session.
+
+### 5.6 System prompt (draft, refined in Plan B)
+
+> You are in a ClaudeDo planning session for a task. Your job is to brainstorm with the user, then break their rough intent into concrete, independently-executable child-tasks. Each child-task should be something a single automated agent can pick up and complete autonomously. Use the `mcp__claudedo__*` tools to create/update/delete drafts in real time. You may read the repository for context (Read/Grep/Glob) but must not modify any files. When the user is satisfied, call `finalize`. Skills you may find useful: `superpowers:writing-plans`, `superpowers:writing-clearly-and-concisely`.
+
+### 5.7 Initial prompt (template)
+
+```
+<Parent task title>
+
+<Parent task description, if any>
+
+---
+We're planning this task together. Brainstorm with me, then create concrete child-tasks via the MCP tools. I'll call `finalize` when we're done.
+```
+
+### 5.8 Unknowns to resolve during Plan B implementation
+
+These are left **open** in this spec; they'll be pinned down during implementation via `mcp__plugin_context7_context7__query-docs` for the Claude Code CLI:
+
+1. Exact flag for thinking budget (`--thinking-budget medium`? model suffix `claude-sonnet-4-6-thinking`? something else?).
+2. Exact casing of tool names in `--allowedTools` (`Read`/`read`, `WebFetch`/`web_fetch`, `Skill`).
+3. Whether `--append-system-prompt` accepts a file reference (`@path`) or requires inline string.
+4. Whether Claude CLI supports a `--session-id` flag for pre-assigning the session ID, or whether we must read it back from `~/.claude/projects/<hash>/sessions/` after the process starts.
+
+If (4) resolves to "read back", strategy:
+- Poll `~/.claude/projects/<hash>/sessions/` directory modtimes shortly after launch; newest session file after launch timestamp is ours.
+- Cache the result on the parent task via `UpdatePlanningSessionIdAsync`.
+- If session ID can't be captured, Resume falls back to `claude --continue` (last session in that project).
+
+### 5.9 Pre-flight checks
+
+On `LaunchAsync`:
+- `wt.exe` resolvable in PATH → else throw `PlanningLaunchException("Windows Terminal not found")`, UI shows install hint.
+- `claude` resolvable in PATH → else `PlanningLaunchException("Claude CLI not installed")`.
+- `list.WorkingDir` exists → else `PlanningLaunchException("Working directory not found: <path>")`.
+
+---
+
+## 6. UI Changes
+
+### 6.1 Context menu (`TaskRowView.axaml`)
+
+New entries, conditional on status:
+- `Manual` + `ParentTaskId IS NULL` → **"Open planning Session"**
+- `Planning` → **"Resume planning Session"** and **"Discard planning session"**
+- `Planned` / `Done` / `Failed` (parent) → no planning-related entries (7c: no re-planning).
+- Children (`ParentTaskId IS NOT NULL`) → never show planning entries.
+
+### 6.2 Hierarchy rendering (`TasksIslandView.axaml`)
+
+Approach: **flat stream with indentation**, not a `TreeView`.
+
+- `TasksIslandViewModel` builds `OpenItems`/`CompletedItems`/etc. as flat `ObservableCollection<TaskRowViewModel>` with parents followed by their children if expanded.
+- `TaskRowViewModel` gets `IsChild: bool` and `IsPlanningParent: bool` and `IsExpanded: bool`.
+- `TaskRowView` indents 24px when `IsChild`, shows a thin left border in `TextFaintBrush`.
+- Parents with `IsPlanningParent` render a chevron (▸/▾) that toggles `IsExpanded`; collapsed parents hide their children from the flat stream.
+- Expanded-state map kept in the VM (`Dictionary<string, bool>`, default `true`).
+
+### 6.3 Draft and planning styling (`TaskRowView`)
+
+- `Status = Draft` → row italic, 70% opacity, small left-aligned badge "DRAFT".
+- Parent `Status = Planning` → badge "PLANNING" (accent: warning-amber).
+- Parent `Status = Planned` → badge "PLANNED" (accent: neutral-blue).
+
+### 6.4 Unfinished-session dialog
+
+Trigger: on app start **and** on any context-menu click against a `Planning` parent.
+
+Modal (built with existing `TaskCompletionSource<T>` dialog pattern):
+
+```
+Unfinished planning session
+"<Parent title>"
+<N> draft tasks waiting to be finalized.
+
+   [Resume]   [Finalize now]   [Discard]
+```
+
+- Resume → `ResumePlanningSessionAsync`, opens terminal with `--resume`.
+- Finalize now → `FinalizePlanningSessionAsync` (server-side, no terminal). Useful when the user is confident drafts are good.
+- Discard → `DiscardPlanningSessionAsync`.
+
+### 6.5 TasksIslandViewModel commands
+
+- `[RelayCommand] OpenPlanningSessionAsync(TaskRowViewModel? row)`
+- `[RelayCommand] ResumePlanningSessionAsync(TaskRowViewModel? row)`
+- `[RelayCommand] DiscardPlanningSessionAsync(TaskRowViewModel? row)`
+- `[RelayCommand] FinalizePlanningSessionAsync(TaskRowViewModel? row)`
+- `[RelayCommand] ToggleExpand(TaskRowViewModel parentRow)`
+
+### 6.6 WorkerClient additions (`ClaudeDo.Ui/Services/WorkerClient.cs`)
+
+- `Task<PlanningSessionLaunchInfo> StartPlanningSessionAsync(string taskId, CancellationToken ct)` — returns `{ WorkingDir, McpConfigPath, InitialPromptPath, SystemPromptPath }`.
+- `Task<PlanningSessionResumeInfo> ResumePlanningSessionAsync(string taskId, CancellationToken ct)` — returns `{ WorkingDir, McpConfigPath, ClaudeSessionId }`.
+- `Task<int> FinalizePlanningSessionAsync(string taskId, CancellationToken ct)` — returns finalized count.
+- `Task DiscardPlanningSessionAsync(string taskId, CancellationToken ct)`.
+- `Task<int> GetPendingDraftCountAsync(string taskId, CancellationToken ct)` — for the unfinished-session dialog.
+
+Existing `TaskUpdated` event covers live draft updates; no new event needed.
+
+### 6.7 Delete handling
+
+When the user tries to delete a parent with children:
+- Repository throws `DbUpdateException` (FK Restrict).
+- UI catches, shows: "This task has N child tasks. Discard drafts and delete? / Delete all including children? / Cancel."
+- "Delete all including children" → UI iterates children and deletes them first, then the parent.
+- "Discard drafts" option only appears if parent status is `Planning` (drafts exist to discard).
+
+---
+
+## 7. Lifecycle & Error Handling
+
+### 7.1 Worker queue isolation
+
+`GetNextQueuedAgentTaskAsync` filters on `Status = Queued` — Planning/Planned/Draft are excluded by status. Add explicit regression test to lock this in.
+
+### 7.2 Parent auto-completion (repeat of 2, for implementation reference)
+
+After `MarkDoneAsync`/`MarkFailedAsync`:
+```csharp
+if (task.ParentTaskId is not null)
+    await TryCompleteParentAsync(task.ParentTaskId, ct);
+```
+where `TryCompleteParentAsync` loads children, checks terminal status, sets parent accordingly.
+
+### 7.3 Session-start errors
+
+Table in §5.9 Pre-flight checks. UI receives typed exceptions, shows appropriate dialog.
+
+### 7.4 Session-runtime errors
+
+- Terminal crashes → drafts + token persist. Resume via dialog (§6.4).
+- Worker restart → drafts + token persist. Resume rebuilds HTTP connection.
+- MCP call fails transiently → Claude CLI retries or the model reports the error to the user in terminal; drafts remain in whatever state the last successful call left them.
+- No session timeout — brainstorming may be long.
+
+### 7.5 Concurrency
+
+- Different parents → independent sessions, one token per parent.
+- Same parent launched twice → `StartPlanningSessionAsync` throws; UI says "Already planning; use Resume".
+- Cleanup on app exit: nothing — planning state is fully persisted in DB and files.
+
+---
+
+## 8. Testing
+
+### 8.1 Automated (in `ClaudeDo.Worker.Tests`)
+
+**Schema & repository:**
+- Migration applies cleanly on fresh DB.
+- `GetChildrenAsync` returns only direct children, sorted.
+- `CreateChildAsync` sets Status=Draft, ParentTaskId correctly.
+- `FinalizePlanningAsync` transactionally transitions drafts to Manual/Queued, sets parent to Planned, sets timestamp, clears token. On simulated DB error, rolls back fully.
+- `DiscardPlanningAsync` removes drafts, resets parent.
+- `GetNextQueuedAgentTaskAsync` ignores Drafts, Planning parents, Planned parents.
+- `Restrict` cascade: delete parent with children throws `DbUpdateException`.
+
+**Auto-status hook (§7.2):**
+- All children Done → parent Done.
+- Mix: some Done, at least one Failed, rest in terminal state → parent Failed.
+- Mix with one still Running → parent stays Planned.
+- Parent stays Planned while any Draft exists (defensive — finalize should have cleared them).
+
+**MCP handlers (against SQLite + in-process HTTP):**
+- Valid token → tool executes.
+- Missing/invalid token → 401.
+- `create_child_task` → creates Draft, emits TaskUpdated event.
+- `update_child_task` on non-Draft → MCP error.
+- `delete_child_task` on non-Draft → MCP error.
+- `finalize` called twice: first succeeds, second errors because token is invalidated.
+- Cross-parent access: tool with `task_id` belonging to another parent's session → MCP error.
+
+**SignalR endpoints (integration with Worker host):**
+- Start → token generated, session directory + files created, `mcp.json` contains token.
+- Start on already-`Planning` parent → error.
+- Resume → no new token, reads `PlanningSessionId` from DB.
+- Discard → drafts gone, directory removed, token NULL, parent back to Manual.
+
+### 8.2 Manual (added to `docs/open.md` checklist)
+
+- Windows Terminal spawn with real `wt.exe`.
+- Real Claude CLI end-to-end session (requires `ANTHROPIC_API_KEY`).
+- Avalonia hierarchy rendering (chevron, indentation, draft styling, badges).
+- Session-ID capture from `~/.claude/projects/...` (timing-sensitive, platform-specific).
+
+---
+
+## 9. Phasing
+
+Work is delivered in **three sequential-then-parallel** plans. Plan A must merge before B and C can merge.
+
+### 9.1 Plan A — Foundation
+
+Schema migration, enum additions, repository methods, auto-status hook, delete-Restrict, regression test for queue filter. No UI-visible changes (other than delete-with-children now failing with a generic error until Plan C handles it).
+
+Scope files (approximate):
+- `src/ClaudeDo.Data/Models/TaskEntity.cs`
+- `src/ClaudeDo.Data/Configuration/TaskEntityConfiguration.cs`
+- `src/ClaudeDo.Data/Migrations/<new>_AddPlanningSupport.cs`
+- `src/ClaudeDo.Data/Repositories/TaskRepository.cs` (+ `ITaskRepository`)
+- `src/ClaudeDo.Worker/...` auto-status hook call-site updates.
+- `tests/ClaudeDo.Worker.Tests/...` new test classes.
+
+### 9.2 Plan B — Worker MCP + SignalR + Launcher (starts after A merges)
+
+MCP service with HTTP transport, token auth, six tools. New SignalR hub endpoints for Start/Resume/Discard/Finalize/GetPendingDraftCount. Session directory management. `IPlanningTerminalLauncher` implementation for `wt.exe`. Resolves the four unknowns from §5.8.
+
+Scope files (approximate):
+- `src/ClaudeDo.Worker/Planning/PlanningMcpService.cs` (new)
+- `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs` (new)
+- `src/ClaudeDo.Worker/Hub/WorkerHub.cs` (extend)
+- `src/ClaudeDo.Worker/Program.cs` (DI + endpoint mapping)
+- `src/ClaudeDo.App/` or `src/ClaudeDo.Ui/Services/` — `IPlanningTerminalLauncher` + `WindowsTerminalPlanningLauncher`.
+- `tests/ClaudeDo.Worker.Tests/Planning/...`
+
+### 9.3 Plan C — UI (parallel to B after A merges)
+
+Context menu entries, hierarchy rendering, draft styling, unfinished-session dialog, WorkerClient extensions, delete-with-children handling. During parallel development, mocks the WorkerClient against Plan B's interface contract.
+
+Scope files (approximate):
+- `src/ClaudeDo.Ui/ViewModels/Islands/TasksIslandViewModel.cs`
+- `src/ClaudeDo.Ui/ViewModels/Islands/TaskRowViewModel.cs`
+- `src/ClaudeDo.Ui/Views/Islands/TasksIslandView.axaml`
+- `src/ClaudeDo.Ui/Views/Islands/TaskRowView.axaml`
+- `src/ClaudeDo.Ui/Services/WorkerClient.cs`
+- `src/ClaudeDo.Ui/Design/IslandStyles.axaml` (draft/badge styling)
+- `src/ClaudeDo.Ui/Views/Dialogs/UnfinishedPlanningDialog.axaml` (new)
+
+### 9.4 Integration points between B and C
+
+Interface contract locked before parallel work begins:
+- SignalR method names, parameters, return DTOs (listed in §6.6).
+- `TaskUpdated` event payload unchanged; carries the task's new parent-id and status so the UI can re-bucket.
+- Session directory path shape: `~/.todo-app/planning-sessions/<parentTaskId>/`.
+- `mcp.json` and session-file formats are internal to Plan B; UI never reads them.
+
+---
+
+## 10. Out of scope (for now)
+
+- Nested planning (children of children). Explicitly one level.
+- Cross-list planning (parent in list A, children in list B).
+- Multi-user collaboration on the same planning session.
+- Session timeouts / auto-discard.
+- Planning-session history / audit UI. Directory is kept on finalize but not surfaced.
+- Re-planning a finalized parent (7c: no).

+# Self-Update for App and Installer — Design
+
+**Date:** 2026-04-23
+**Status:** Approved
+
+## Goals
+
+Give ClaudeDo two update paths:
+
+- **A — App-side update check:** the Avalonia UI checks Gitea for a newer release on startup (and via a manual menu action) and surfaces a dismissible banner. Clicking **Update now** launches the locally installed installer in Update mode and closes the UI.
+- **B — Installer self-update:** the WPF installer checks for a newer installer binary on launch and offers to replace itself before continuing. After replacement, it proceeds with its normal wizard.
+
+Non-goals:
+
+- No silent/background auto-apply of updates. The user always initiates the final update action.
+- No periodic in-app polling (startup + manual only).
+- No changes to the release pipeline — release assets (`ClaudeDo-<version>-win-x64.zip`, `ClaudeDo.Installer-<version>.exe`, `checksums.txt`) stay as they are.
+
+## Architecture Overview
+
+A new shared library, `ClaudeDo.Releases`, hosts the release-API client, version comparison, checksum verification, and installer self-update logic. Both `ClaudeDo.Installer` and `ClaudeDo.Ui` reference it. This removes the existing duplication between the installer's release plumbing and what the app needs, and keeps a single asset-matching / version-parsing code path.
+
+```
+ClaudeDo.Releases  (new, netstandard2.0 or net8.0)
+├── ReleaseClient.cs        (moved from Installer/Core)
+├── IReleaseClient.cs       (moved)
+├── ChecksumVerifier.cs     (moved)
+├── VersionComparer.cs      (new)
+└── SelfUpdater.cs          (new — installer self-update mechanism)
+
+ClaudeDo.Installer  (WPF, consumes ClaudeDo.Releases)
+├── App.xaml.cs             (modified — SelfUpdater + --replace-self arg)
+└── Core/InstallModeDetector.cs  (modified — now uses VersionComparer)
+
+ClaudeDo.Ui  (Avalonia, consumes ClaudeDo.Releases)

+├── ViewModels/MainViewModel.cs     (modified — banner + Help menu state)
+└── Views/MainWindow.axaml          (modified — banner + Help dropdown)
+```
+
+## Part A — App-Side Update Check
+
+### `ClaudeDo.Ui/Services/UpdateCheckService.cs`
+
+Responsibilities:
+
+- Read the current app version from `Assembly.GetExecutingAssembly().GetName().Version`.
+- Call `IReleaseClient.GetLatestReleaseAsync` to fetch the Gitea release.
+- Use `VersionComparer` to decide whether the latest is newer.
+- Expose observable properties: `IsUpdateAvailable`, `LatestVersion`, `CurrentVersion`, `IsChecking`, `LastCheckStatus` (`UpToDate | UpdateAvailable | CheckFailed | NeverChecked`).
+- Expose a `CheckNowAsync` method for the manual Help menu action.
+
+Lifecycle:
+
+- Registered as a singleton in DI.
+- Startup check is fired from `MainViewModel` once the main window is shown. It runs fire-and-forget on a background `Task`; UI never blocks on it.
+- Manual check is awaited by its command and briefly shows a status message (see UI).
+
+Error handling:
+
+- Network / API errors → log to `~/.todo-app/logs/`, set `LastCheckStatus = CheckFailed`, do not surface a banner. Manual check shows a small inline status only.
+
+### `ClaudeDo.Ui/Services/InstallerLocator.cs`
+
+Responsibilities:
+
+- Resolve the path to the installed `ClaudeDo.Installer.exe` so the UI can launch it.
+
+Discovery strategy (first hit wins):
+
+1. Walk up from `AppContext.BaseDirectory` looking for a sibling `install.json`. The installer is at `{installDir}/uninstaller/ClaudeDo.Installer.exe`.
+2. Fall back to reading `HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\ClaudeDo\InstallLocation` (written by the existing `WriteUninstallRegistryStep`).
+
+If neither yields a valid path, the banner's **Update now** button is disabled with a tooltip explaining the installer could not be located.
+
+### UI changes
+
+**Banner** at the top of `MainView` (above content, below custom chrome):
+
+- Visible when `UpdateCheckService.IsUpdateAvailable == true` and the user has not dismissed this session.
+- Text: `Update available: v{CurrentVersion} → v{LatestVersion}`.
+- Actions: `Update now` (primary), `Dismiss` (sets a transient `IsBannerDismissed` flag that resets on app restart — intentionally not persisted so the banner returns next launch if still relevant).
+- Styled to match existing chrome/accent conventions (compact, dismissible, non-modal).
+
+**Help dropdown** in the custom titlebar:
+
+- New menu: `Help`.
+- First item: `Check for updates` → binds to `MainViewModel.CheckForUpdatesCommand`, which calls `UpdateCheckService.CheckNowAsync`.
+- When a check completes:
+  - `UpdateAvailable` → banner appears (no separate dialog).
+  - `UpToDate` → a brief inline status in the banner area: `You're up to date (v{CurrentVersion})`, auto-hides after ~3 seconds.
+  - `CheckFailed` → `Could not check for updates` inline message, auto-hides after ~3 seconds.
+- Leaves room for future items (`About`, `Documentation`, etc.).
+
+### Update action flow
+
+1. User clicks **Update now** in the banner.
+2. `MainViewModel` resolves the installer path via `InstallerLocator`.
+3. UI spawns `ClaudeDo.Installer.exe` with no arguments. The installer's existing `InstallModeDetector` reads `install.json` alongside it, hits Gitea, and enters `Update` mode.
+4. UI closes itself immediately after spawning the process.
+5. The installer performs its standard update flow: `StopServiceStep` → `DownloadAndExtractStep` → `StartServiceStep`.
+6. When the user clicks Finish the installer exits. The user re-launches the app via their existing shortcut.
+
+No IPC between UI and installer is needed — the installer is already self-sufficient once launched against an existing install directory.
+
+## Part B — Installer Self-Update
+
+### `ClaudeDo.Releases/SelfUpdater.cs`
+
+Runs from `ClaudeDo.Installer/App.xaml.cs` before any window is shown.
+
+Flow:
+
+1. **Handle `--replace-self` argument first.** If the installer was launched with `--replace-self "<old-path>"`:
+   - Wait up to 5 seconds for the old process to exit (poll for file lock release).
+   - Delete `<old-path>`.
+   - Copy own exe to `<old-path>`.
+   - Start a new process at `<old-path>` with no args, then exit the current (temp) process. This ensures the user's shortcut or Apps & Features entry now points at the updated binary.
+   - If any step fails, fall through to the normal wizard (the user still has a working installer, just in a temp location).
+
+2. **Check for a newer installer.** If no `--replace-self` arg:
+   - Parse own assembly version.
+   - Fetch latest release.
+   - Find the installer asset matching `ClaudeDo.Installer-<version>.exe` (regex: `^ClaudeDo\.Installer-(?<version>[\d\.]+)\.exe$`).
+   - Compare via `VersionComparer`.
+   - If not newer, or if check fails, proceed to the normal wizard (existing Config-mode fallback behavior).
+
+3. **Prompt if newer.** Show a small modal dialog (plain WPF `Window`, reusing the installer's titlebar/accent styles):
+   > *"A newer installer is available: v{latest}. Update before continuing?"*
+   > `[Update] [Continue anyway] [Cancel]`
+
+   - **Cancel** → `Application.Current.Shutdown(0)`.
+   - **Continue anyway** → proceed to normal wizard.
+   - **Update** → run relaunch sequence.
+
+4. **Relaunch sequence:**
+   - Download to `%TEMP%\ClaudeDo.Installer-<version>.exe` (show a minimal inline progress UI; no separate window).
+   - Verify against `checksums.txt` from the release via `ChecksumVerifier`. On failure, show error with `[Continue with current installer]` action → proceed to wizard.
+   - `Process.Start` new exe with args `--replace-self "<current-exe-path>"`.
+   - Exit current process.
+
+### Why `--replace-self` rather than a shell script
+
+A child process holding a handle to the new exe is reliable cross-Windows-version. Relying on a `.bat` or `cmd /c` helper leaves a file that we would need to clean up, and behaves badly when the installer was launched from a mounted share or non-ASCII path. The `--replace-self` approach keeps everything in managed code and uses a single exe throughout.
+
+### Edge case: running from `uninstaller/` copy
+
+When the installer runs from `{installDir}/uninstaller/ClaudeDo.Installer.exe` (via the app's **Update now** or from Apps & Features), the self-update flow is identical. It is desirable for the uninstaller copy to be kept current — stale uninstaller binaries would otherwise drift behind and could have bugs the new app release expects fixed.
+
+## Version Comparison (`VersionComparer`)
+
+Centralizes the logic currently in `InstallModeDetector.IsNewer`:
+
+- Parses both versions as `System.Version` after trimming a leading `v` / `V`.
+- Returns `(bool isNewer, bool unparseable)`.
+- Unparseable (e.g. `0.2.0-beta`) → treated as not newer; callers can surface a hint if desired.
+
+Both `InstallModeDetector` (existing behavior) and `SelfUpdater` / `UpdateCheckService` (new callers) share this logic.
+
+## Error Handling Summary
+
+| Scenario | App behavior | Installer behavior |
+|---|---|---|
+| Gitea unreachable | Silent; log to file; no banner | Silent; skip self-update; proceed to wizard |
+| JSON parse error | Same as unreachable | Same as unreachable |
+| Version unparseable | No banner; log a hint | No prompt; proceed |
+| Installer exe not found on disk | `Update now` button disabled with tooltip | N/A |
+| Download fails | N/A (app delegates to installer) | Error dialog with `[Continue with current installer]` |
+| Checksum mismatch | N/A | Error dialog with `[Continue with current installer]` |
+| Relaunch fails | N/A | Error dialog; user keeps temp exe and current exe both |
+
+## Testing
+
+**New test project: `tests/ClaudeDo.Releases.Tests`**
+
+- `ReleaseClientTests` — move existing installer tests covering `GetLatestReleaseAsync` and `DownloadAsync`.
+- `VersionComparerTests` — boundary cases (equal, newer, older, unparseable, mixed `v`-prefix).
+- `SelfUpdaterTests`:
+  - Asset-name regex correctly isolates version from `ClaudeDo.Installer-0.3.0.exe` and ignores `ClaudeDo-0.3.0-win-x64.zip`.
+  - Decision logic given mocked `IReleaseClient` responses.
+  - `--replace-self` handler: given a temp dummy file, the handler waits, deletes, copies — verified with a mock filesystem / temp dir.
+
+**Existing project: `tests/ClaudeDo.Installer.Tests`**
+
+- `SelfUpdateIntegrationTest`: build the installer, invoke it with `--replace-self <dummy>` pointing at a temp file, assert the dummy is replaced by a copy of the test installer, and the process exits cleanly. Run only on Windows CI.
+
+**App tests (`tests/ClaudeDo.Ui.Tests` — add if absent):**
+
+- `UpdateCheckServiceTests` — stubbed `IReleaseClient`, assert state transitions for each status.
+- `InstallerLocatorTests` — fake filesystem, verify walk-up and registry-fallback discovery.
+
+**Manual verification** (add to `docs/open.md`):
+
+1. Build `v0.2.x` installer and upload to a test Gitea release.
+2. Tag `v0.3.0` with new installer asset.
+3. Install `v0.2.x`, run the `v0.2.x` installer again — confirm self-update prompt appears and replaces the binary in place.
+4. With `v0.2.x` installed and a v0.3.0 release published, launch the app — confirm banner appears, **Update now** launches installer, update completes, app relaunches at v0.3.0.
+5. Pull the network during check in both places — confirm silent fallback, no user-visible errors.

+# Worker Log Footer — Design
+
+Date: 2026-04-23
+
+## Goal
+
+Surface important Worker lifecycle events (worktree created, Claude started, merged, etc.) in the UI footer as a single rotating, color-coded line. Gives the user ambient awareness of what the Worker just did without opening task details.
+
+## Non-Goals
+
+- No log history, drawer, or scrollback
+- No filtering or user-configurable verbosity
+- No persistence across UI restarts
+- No replay of events missed while UI was disconnected
+
+## UX
+
+Footer (`MainWindow.axaml`, row 2) layout changes from `StackPanel` to `DockPanel`:
+
+- **Docked left:** existing connection pill (ellipse + `ONLINE/OFFLINE/RECONNECTING` text). The static `· WORKER` label is removed; the rotating log line replaces its purpose.
+- **Docked right:** rotating worker-log line.
+
+Line format: `14:32 · <message>`, rendered in the mono font at size 10 (matches existing footer typography). `TextTrimming="CharacterEllipsis"` so long task titles don't push out the connection pill.
+
+The line is hidden when no event has been received within the last 30 seconds. Each new event replaces the current text and resets the 30-second timer. Timestamp is local time, `HH:mm`.
+
+### Color mapping
+
+Level is rendered via a `WorkerLogLevelToBrushConverter` (mirrors existing `StatusColorConverter` pattern):
+
+| Level     | Brush / color          | Events                                              |
+|-----------|------------------------|-----------------------------------------------------|
+| `Info`    | `TextDimBrush` (dim)   | Created worktree, Started Claude, Committed changes |
+| `Success` | `#4CAF50` green        | Merged, Finished (done)                             |
+| `Warn`    | `#FFA726` amber        | Discarded worktree, Reset                           |
+| `Error`   | `#EF5350` red          | Finished (failed)                                   |
+
+## Event Catalog
+
+Seven emit sites. Each is added alongside the existing `_logger.LogInformation(...)` call — no log-sink plumbing, no central event bus.
+
+| Site                                      | Level     | Message                                 |
+|-------------------------------------------|-----------|-----------------------------------------|
+| `WorktreeManager.CreateAsync`             | `Info`    | `Created worktree for "<title>"`        |
+| `WorktreeManager.DiscardAsync`            | `Warn`    | `Discarded worktree for "<title>"`      |
+| `TaskMergeService.MergeAsync`             | `Success` | `Merged "<title>" into <target>`        |
+| `TaskResetService.ResetAsync`             | `Warn`    | `Reset "<title>"`                       |
+| `TaskRunner` — Claude launch              | `Info`    | `Started Claude for "<title>"`          |
+| `TaskRunner` — auto-commit                | `Info`    | `Committed changes in "<title>"`        |
+| `TaskRunner` — task finished              | `Success` / `Error` | `Finished "<title>" (<status>)` |
+
+`<title>` is the task's display title; `<target>` is the merge target branch; `<status>` is `done` or `failed`.
+
+## Architecture
+
+### Shared contract (`ClaudeDo.Data`)
+
+New enum:
+
+```csharp
+namespace ClaudeDo.Data.Models;
+
+public enum WorkerLogLevel
+{
+    Info,
+    Success,
+    Warn,
+    Error,
+}
+```
+
+SignalR is configured to serialize enums as strings via `JsonStringEnumConverter` (added to the hub's JSON options in `Program.cs`). The UI client deserializes back to the same enum.
+
+### Server side (`ClaudeDo.Worker`)
+
+`HubBroadcaster` gets a new method:
+
+```csharp
+public Task WorkerLog(string message, WorkerLogLevel level, DateTime timestampUtc) =>
+    _hub.Clients.All.SendAsync("WorkerLog", message, level, timestampUtc);
+```
+
+`HubBroadcaster` is already injected into `TaskRunner`. For `WorktreeManager`, `TaskMergeService`, and `TaskResetService`, add constructor injection where it isn't already present. Each emit site calls `_broadcaster.WorkerLog(...)` with `DateTime.UtcNow` next to the existing `_logger.LogInformation(...)`.
+
+### Client side (`ClaudeDo.Ui`)
+
+**`WorkerClient`** — register a `HubConnection.On<string, WorkerLogLevel, DateTime>("WorkerLog", ...)` handler and expose a `WorkerLogReceived` event with a small `WorkerLogEntry(string Message, WorkerLogLevel Level, DateTime TimestampUtc)` record.
+
+**Footer VM** — `StatusBarViewModel` already exists; extend it (or introduce a small `FooterViewModel` if `StatusBarViewModel` turns out to be scoped elsewhere — confirm during implementation). Add:
+
+- `[ObservableProperty] string? currentEventText`
+- `[ObservableProperty] WorkerLogLevel currentEventLevel`
+- `[ObservableProperty] bool isEventVisible`
+- A `DispatcherTimer` with a 30-second interval. On each `WorkerLogReceived`:
+  1. Format `HH:mm · <message>` from the event's local time.
+  2. Set `CurrentEventText`, `CurrentEventLevel`, `IsEventVisible = true`.
+  3. Stop and restart the timer.
+- On timer tick: `IsEventVisible = false`, `CurrentEventText = null`.
+
+**XAML** — `MainWindow.axaml` footer `StackPanel` becomes a `DockPanel`. Existing ellipses + connection text dock left in a horizontal `StackPanel`. A new `TextBlock` docks right, bound to `CurrentEventText` with `Foreground="{Binding CurrentEventLevel, Converter={StaticResource WorkerLogLevelToBrush}}"`, `IsVisible="{Binding IsEventVisible}"`, and `TextTrimming="CharacterEllipsis"`. Same mono font / size 10 as the rest of the footer.
+
+**Converter** — `WorkerLogLevelToBrushConverter` in `Converters/` returns a brush per enum value, resolving theme brushes via `Application.Current.Resources` for `Info` (to honor theme swaps) and hard-coding the success/warn/error hex values (those are already hard-coded in the current footer).
+
+## Testing
+
+- Unit test `WorkerLogLevelToBrushConverter` with each enum value.
+- Unit test the footer VM: receiving an event sets text/level/visibility and schedules a clear; a second event within 30s replaces and resets the timer; after 30s of silence the line hides.
+- Manual smoke: run a task end-to-end and confirm each of the seven events surfaces with the expected color and copy.
+
+## Edge Cases
+
+- **UI disconnected during an event:** event is lost. Acceptable — reconnect resumes receiving new events.
+- **Burst of events:** each replaces the previous; only the most recent is shown.
+- **Long task title:** ellipsized by the TextBlock; connection pill on the left stays fully visible.
+- **Clock skew between Worker and UI:** timestamp is formatted in UI's local time from the wire-format `DateTime` (sent as UTC). Minor skew is cosmetic; no correctness impact.
+
+## Out of Scope / Future
+
+- Click-to-expand history drawer
+- Per-list or per-task event filtering
+- Persisting the most recent N events across restarts

+# Planning Merge-All & Subtask Visibility — Design
+
+**Date:** 2026-04-24
+**Status:** Approved design, ready for implementation planning
+
+## Problem
+
+Three concrete issues with the current Planning feature:
+
+1. **Queued subtasks are not visible in the Queue List.** When a planning session finalizes, its subtasks transition to `Queued`, but the Queue List's hierarchy rules only show children when their Planning parent is expanded. A collapsed (or already-`Planned`) parent effectively hides the subtasks.
+2. **Completed subtasks vanish from view.** Once a subtask becomes `Done`, the regroup logic moves it to the "Completed" bucket. Users expect subtasks to remain visible under their Planning parent until the Planning task itself is marked Done.
+3. **No aggregated view or bulk merge.** Each subtask must be merged individually through its worktree. There is no way to see a combined diff of all changes produced by a Planning session, and no "merge everything" action.
+
+## Goals
+
+- Treat Planning subtasks as belonging to their Planning parent for visibility and lifecycle purposes.
+- Provide a single aggregated diff view that shows all changes produced by a Planning session.
+- Provide a single "Merge all" action that sequentially merges all subtasks, with a usable conflict-resolution flow.
+- Auto-complete the Planning task when all merges succeed.
+
+## Non-goals
+
+- Building a full-featured in-app diff editor. Textual unified diff is acceptable for now; conflict *editing* happens in VS Code.
+- Persisting Merge-all progress across worker restarts. Restart clears in-memory orchestration state; user re-starts Merge-all (already-merged subtasks are skipped because their worktrees are `Merged`).
+- Modifying how individual subtasks are created, executed, or finalized.
+
+## Design
+
+### 1. Visibility model
+
+Planning subtasks are exclusively children of their Planning parent until the Planning task transitions to `Done`. The Planning parent acts as a roll-up in the Queue List.
+
+- Tasks with a non-null `ParentTaskId` are excluded from all virtual lists (`virtual:queued`, `virtual:running`, `CompletedItems`, etc.) as separate rows.
+- A Planning/Planned task is included in `virtual:queued` if **any** child is `Queued`, and in `virtual:running` if any child is `Running`.
+- Children are always attached under their parent in the task tree; expansion purely controls visual collapse.
+- When Merge-all completes successfully, the Planning task is set to `Done` and the entire subtree moves to Completed together.
+- Status badge on the Planning row summarizes children (e.g., `3/5 queued`, `2 running`, `1 failed`).
+
+### 2. Planning detail panel
+
+Extends the existing task detail view. New elements when the selected task is a Planning task:
+
+- **Subtasks list.** Grouped by status badge (Queued / Running / Done / Failed). Each row preserves existing per-subtask actions (view logs, open worktree, individual merge).
+- **Merge target dropdown.** Single target branch that applies to all subtasks in Merge-all. Defaults to the branch that was current when the Planning session started.
+- **`[Review combined diff]` button.** Opens the Aggregated Diff Viewer. Enabled as soon as any subtask has produced a diff.
+- **`[Merge all subtasks]` button.** Orchestrates sequential merge + auto-Done. Disabled until every subtask is `Done` and every worktree is `Active` or `Merged` (no `Discarded` / `Kept`). Tooltip explains why when disabled (e.g., "2 subtasks still running", "1 subtask failed — resolve first", "1 worktree was discarded").
+- Existing per-subtask merge action remains available; Merge-all is additive.
+
+### 3. Aggregated diff viewer
+
+New Avalonia view `PlanningDiffView` + `PlanningDiffViewModel`, opened as a modal or dedicated tab.
+
+**Default — grouped by subtask:**
+- Left pane: subtask list in creation order with `title • +added −deleted • N files`.
+- Right pane: selected subtask's diff. Reuse any existing diff-rendering control; if none exists, render unified diff text with basic syntax coloring (monospace, minimal decoration).
+- Summary stats come from `WorktreeEntity.DiffStat`. Raw diff comes from `git diff <base>..<head>` executed in each subtask's worktree via `GitService`. Cached in memory per subtask until the subtask's HEAD moves.
+
+**Toggle — "Preview combined diff":**
+- Calls `PlanningAggregator.BuildIntegrationBranchAsync(planningTaskId, targetBranch, ct)`:
+  1. Create/reset branch `planning/<slug>-integration` off the current merge target.
+  2. Merge each subtask's branch sequentially with `--no-ff`.
+  3. On conflict during preview: abort the merge, reset the integration branch, surface a warning identifying which two subtasks conflict. Grouped view remains available.
+  4. On success: compute `git diff <merge-target>..planning/<slug>-integration` and render as a single flat unified diff.
+- Toggle flips back to grouped mode.
+
+**Integration-branch lifecycle:** scratch artifact, rebuilt on every preview (deleted + recreated). Cleaned up when the Planning task is marked `Done` or when the Planning session is discarded.
+
+### 4. Merge-all orchestration
+
+**Happy path (`PlanningMergeOrchestrator.StartAsync`):**
+
+1. Pre-flight checks — fail fast with a clear message on any:
+   - Every subtask is `Done`.
+   - Every subtask's worktree is `Active` or `Merged` (no `Discarded` / `Kept`). `Merged` worktrees are allowed so that an interrupted Merge-all can be restarted.
+   - Repo working tree is clean.
+   - No mid-merge in progress in the target repo.
+2. For each subtask in creation order, skip if its worktree is already `Merged` (idempotent restart). Otherwise call `TaskMergeService.MergeAsync` with `removeWorktree: true` and `leaveConflictsInTree: true`. Each success flips the worktree to `Merged`.
+3. After the last successful merge:
+   - Set Planning task `Status = Done`.
+   - Call `PlanningAggregator.CleanupIntegrationBranchAsync` if the integration branch exists.
+   - Emit `PlanningCompleted` so the UI removes the row from the Queue List.
+
+**Conflict path:**
+
+1. `MergeAsync` with `leaveConflictsInTree: true` reports a conflict, leaves the repo in a mid-merge state, and returns the conflicted file paths (`git diff --name-only --diff-filter=U`).
+2. Orchestrator halts the loop, stores the in-progress state (remaining subtasks, target branch, current subtask id) in memory, and emits `PlanningMergeConflict(planningTaskId, subtaskId, conflictedFiles)`.
+3. The UI opens the **Conflict Resolution dialog** — see §5.
+4. On `ContinueAsync`: calls `TaskMergeService.ContinueMergeAsync(subtaskId)` which stages the recorded files and runs `git commit --no-edit`. Flips worktree to `Merged`. Loop resumes with remaining subtasks.
+5. On `AbortAsync`: calls `TaskMergeService.AbortMergeAsync(subtaskId)` which runs `git merge --abort`. Planning stays in `Planned`. Already-merged earlier subtasks remain `Merged`. Orchestration state cleared.
+
+**Idempotent restart:** if the worker restarts mid Merge-all, in-memory state is lost. A fresh `StartAsync` re-runs pre-flight; already-`Merged` worktrees are skipped by the loop (their status gates them out). User experience: "I clicked Merge all again and it continued from where it left off."
+
+### 5. Conflict Resolution dialog
+
+Avalonia modal (`ConflictResolutionView` + `ConflictResolutionViewModel`).
+
+- **Header:** `Conflicts in subtask: <title> merging into <target-branch>`.
+- **File list:** full absolute paths of conflicted files.
+- **`[Open all in VS Code]`** — for each file, spawn `code <absolute-path>` via `Process.Start`. If `code` is not on PATH, show an inline error row with the file list so the user can copy paths manually. No popup-on-popup.
+- **`[I've resolved — continue]`** — calls `ContinuePlanningMerge(planningTaskId)` hub method, closes dialog. The orchestration loop continues with the remaining subtasks.
+- **`[Abort this merge]`** — calls `AbortPlanningMerge(planningTaskId)` hub method, closes dialog. Planning stays `Planned`.
+
+### 6. Data model
+
+**No schema changes.**
+- Conflicted files are queried from git on demand (`git diff --name-only --diff-filter=U`) while the merge is in progress.
+- Integration branch name is derived from the Planning task slug: `planning/<slug>-integration`.
+- Planning completion uses existing `TaskStatus.Done`.
+
+### 7. Services
+
+**New:**
+
+- **`PlanningAggregator`** (`src/ClaudeDo.Worker/Planning/PlanningAggregator.cs`)
+  - `GetAggregatedDiffAsync(planningTaskId, ct)` — returns per-subtask diff entries.
+  - `BuildIntegrationBranchAsync(planningTaskId, targetBranch, ct)` — creates/resets the integration branch, merges subtasks sequentially, returns `(success, combinedDiff)` or `(failure, firstConflictSubtaskId, conflictedFiles)`. Always leaves the integration branch in a consistent state (aborts + resets on failure).
+  - `CleanupIntegrationBranchAsync(planningTaskId, ct)` — deletes the integration branch.
+
+- **`PlanningMergeOrchestrator`** (singleton, `src/ClaudeDo.Worker/Planning/PlanningMergeOrchestrator.cs`)
+  - Owns in-memory state per planning task: `{ remainingSubtasks, targetBranch, currentSubtaskId }`.
+  - `StartAsync(planningTaskId, targetBranch)`, `ContinueAsync(planningTaskId)`, `AbortAsync(planningTaskId)`.
+  - Emits SignalR events: `PlanningMergeStarted`, `PlanningSubtaskMerged`, `PlanningMergeConflict`, `PlanningMergeAborted`, `PlanningCompleted`.
+
+**Modified:**
+
+- **`TaskMergeService`**
+  - `MergeAsync` gets a `leaveConflictsInTree: bool` parameter (default `false`). When `true`, on conflict records conflicted files on the returned result, does **not** call `git merge --abort`.
+  - New `ContinueMergeAsync(taskId, ct)` — stages the recorded conflicted files and runs `git commit --no-edit`, flips worktree to `Merged`.
+  - New `AbortMergeAsync(taskId, ct)` — runs `git merge --abort`, restores pre-merge state.
+  - Existing callers unaffected by the default.
+
+- **`WorkerHub`** — new methods:
+  - `GetPlanningAggregate(planningTaskId)`
+  - `BuildPlanningIntegrationBranch(planningTaskId, targetBranch)`
+  - `MergeAllPlanning(planningTaskId, targetBranch)`
+  - `ContinuePlanningMerge(planningTaskId)`
+  - `AbortPlanningMerge(planningTaskId)`
+
+- **`TasksIslandViewModel.Regroup`**
+  - Exclude tasks with `ParentTaskId != null` from virtual lists.
+  - Include Planning parents in `virtual:queued` / `virtual:running` based on children's statuses.
+  - Keep children attached to parent in the tree at all times until Planning is `Done`.
+
+### 8. UI components (new)
+
+- `PlanningDiffView` + `PlanningDiffViewModel` — aggregated diff viewer (§3).
+- `ConflictResolutionView` + `ConflictResolutionViewModel` — conflict dialog (§5).
+- Planning Detail section inside the existing task detail pane — subtask list + merge target dropdown + two buttons (§2).
+
+## Error handling
+
+- **Pre-flight failures** — surface as inline errors in the Planning detail panel. No merge work attempted.
+- **Preview-build conflict** — keep grouped diff available; show a warning banner identifying the conflicting pair of subtasks.
+- **Merge-all conflict** — Conflict Resolution dialog (§5). The failed subtask's worktree stays `Active`; prior successes stay `Merged`.
+- **VS Code not on PATH** — inline error row in the Conflict dialog with copyable file paths.
+- **Worker restart mid-merge** — in-memory state lost; restarting Merge-all is idempotent because merged worktrees are skipped by status gating.
+
+## Testing
+
+Convention: xUnit integration tests with real SQLite and real git (`tests/ClaudeDo.Worker.Tests`).
+
+**`PlanningAggregatorTests`** — real git fixture
+- `GetAggregatedDiffAsync` returns one entry per subtask with correct stats.
+- `BuildIntegrationBranchAsync` with non-conflicting subtasks — success, branch contains all changes.
+- `BuildIntegrationBranchAsync` with conflicting subtasks — failure, branch reset (not mid-merge), correct subtask id and file list reported.
+- Rebuild overwrites a stale integration branch.
+- `CleanupIntegrationBranchAsync` removes the branch.
+
+**`PlanningMergeOrchestratorTests`** — real git + real DB
+- Happy path: all subtasks merge → worktrees `Merged`, Planning `Done`, `PlanningCompleted` emitted.
+- Conflict path: first subtask conflicts → repo left in conflict state, `PlanningMergeConflict` emitted with correct file list, worktree stays `Active`, Planning stays `Planned`.
+- `ContinueAsync` after conflict: resolution commits, loop proceeds, final state `Done`.
+- `AbortAsync` after conflict: `merge --abort` restores clean state, earlier merged subtasks remain `Merged`, Planning stays `Planned`.
+- Pre-flight rejection: running subtask, failed subtask, dirty repo — each returns the expected error with no side effects.
+- Idempotent restart: partial merge + fresh `StartAsync` — already-`Merged` worktrees skipped.
+
+**`TaskMergeServiceConflictTests`** (extending existing tests)
+- `MergeAsync(leaveConflictsInTree: true)` on conflict: no `merge --abort`, returns conflicted files, worktree state unchanged.
+- `ContinueMergeAsync`: completes in-progress merge, flips worktree to `Merged`.
+- `AbortMergeAsync`: runs `merge --abort`, restores clean state.
+
+**`TasksIslandRegroupTests`** — ViewModel unit tests, no DB
+- Queued subtask with a Planning parent is NOT in `virtual:queued` as its own row.
+- Planning parent with any Queued child IS in `virtual:queued`.
+- Done subtask stays nested under Planning parent until Planning is `Done`.
+- After Planning is marked `Done`, parent + children move to Completed together.
+
+**Manual smoke test** (documented in PR description):
+- End-to-end planning session in the app: create plan, finalize, let subtasks run.
+- Open aggregated diff, toggle Preview combined.
+- Merge-all happy path.
+- Merge-all conflict path with VS Code dialog open/continue.
+- Merge-all conflict path abort.

+# Planning UX Polish + Sequential Subtask Queue
+
+**Status:** design
+**Date:** 2026-04-24
+**Scope:** three small UX changes + one feature — sequential execution of planning subtasks triggered from the context menu.
+
+## Goals
+
+1. Collapse the children of a finished planning-parent row in the task list by default.
+2. Allow the user to collapse the Description section in the Details pane.
+3. Halve the width of the GridSplitters between islands.
+4. Let the user queue all subtasks of a planning parent so they run one after another, with a new `Waiting` status for pending siblings.
+
+## 1. Auto-collapse done planning parents
+
+**Rule for "done":** a planning parent is "done" when every one of its children has `Status == Done`.
+
+**Changes:**
+- `TaskRowViewModel`: add UI-only `[ObservableProperty] bool _areChildrenExpanded`. Default computed from status — `false` when the row is a done planning parent, else `true`. Not persisted.
+- Add `[RelayCommand] void ToggleChildrenExpanded()`.
+- `TasksIslandView.axaml` (or `TaskRowView.axaml`): chevron button on the planning-parent row, visible only when `IsPlanningParent && HasPlanningChildren`. Bound to the toggle command.
+- `TasksIslandViewModel.Regroup()`: before adding child rows to `OpenItems`/`CompletedItems`, check each child's parent row in `Items`. If the parent's `AreChildrenExpanded == false`, skip the child.
+- When a planning parent flips from "not done" → "done" in `OnWorkerTaskUpdated`, call `Regroup()` so the collapse takes effect.
+
+No DB changes.
+
+## 2. Collapsible description in Details pane
+
+**Changes:**
+- `DetailsIslandViewModel`: `[ObservableProperty] bool _isDescriptionExpanded = true` + `[RelayCommand] void ToggleDescriptionExpanded()`.
+- `DetailsIslandView.axaml`: wrap the existing description `TextBox` in a `StackPanel`; add a thin header row with the label "Description" and a chevron button. Body's `IsVisible` binds to the flag.
+- State is per ViewModel instance — reset to `true` whenever a different task is loaded.
+
+No persistence.
+
+## 3. Narrower GridSplitters
+
+`MainWindow.axaml` lines 158 and 170: `Width="5"` → `Width="3"` on both `GridSplitter` elements.
+
+That's the whole change.
+
+## 4. Sequential subtask queue
+
+### Data
+
+- `ClaudeDo.Data/Models/TaskStatus.cs`: add a new enum value `Waiting` (lowercase serialized form `waiting`, matching existing convention).
+- Verify status is stored as string (it should be based on existing patterns). If stored as int, ensure new value gets a stable numeric slot at the end of the enum to avoid breaking existing rows. **No EF migration** beyond what the enum emits automatically.
+
+### Worker
+
+- New SignalR hub method: `QueuePlanningSubtasksAsync(string parentTaskId) : Task`.
+  - Loads all children of the parent, ordered by `SortOrder`.
+  - Validates: parent must be a planning parent, children must currently all be in `Manual` or `Planned` (reject if any child is already Queued/Running/Done/Failed, surface a friendly error).
+  - First child → `Queued`. All other children → `Waiting`. Save.
+  - Emit `TaskUpdated` for each affected task.
+- Chain progression — hook into the existing finish/complete path that already fires `TaskFinished`:
+  - On a child task finishing with status `Done` **and** its parent has waiting siblings: find the next sibling by `(ParentTaskId == parent.Id && Status == Waiting)` ordered by `SortOrder`, flip to `Queued`, emit `TaskUpdated`, and let the existing queue pickup loop pick it up.
+  - On `Failed`: do nothing. Remaining `Waiting` siblings stay waiting. (A toast for failed tasks will be added in a later spec.)
+
+This logic lives in a new `PlanningChainCoordinator` service (or similar) in `ClaudeDo.Worker/Planning/`, registered as a singleton and wired into whatever already emits task-finished events.
+
+### UI
+
+- `TaskRowView` — add context menu entry **"Queue subtasks sequentially"**:
+  - `IsVisible` bound to `IsPlanningParent && HasPlanningChildren`.
+  - `IsEnabled` when all children are in `Manual` / `Planned` state (new property on `TaskRowViewModel`: `CanQueueSubtasksSequentially`).
+  - Calls `WorkerClient.QueuePlanningSubtasksAsync(Id)`.
+- `TaskRowViewModel`:
+  - Add `IsWaiting => Status == TaskStatus.Waiting` and extend `StatusChipClass` switch to return a new class `"waiting"`.
+  - Add `CanQueueSubtasksSequentially` (computed; requires access to children).
+- `StatusColorConverter` — add a muted color for `Waiting` (proposed: the existing `TextMuteBrush` or a faint cyan).
+- Task list — planning parent continues to appear in virtual:queued because it has a `Queued` child (existing logic). **Extend** the virtual:queued match predicate in `TasksIslandViewModel.TaskMatchesList` so a task matches when `Status == Queued || Status == Waiting`. This ensures all sibling subtasks (the queued one + the waiting ones) render under the parent in that list.
+
+### Client
+
+- `IWorkerClient` / `WorkerClient`: add `QueuePlanningSubtasksAsync(string parentTaskId)` that calls the hub method.
+
+## Out of scope
+
+- Toast notifications on subtask failure (separate follow-up spec).
+- Retrying a stopped chain from a failed task (user does it manually via existing actions).
+- Persisting the collapse state of planning parents or the Description across sessions.
+- Drag-to-reorder of waiting subtasks (execution order = `SortOrder` at the moment the chain starts).
+
+## Validation plan
+
+Manual:
+- Plan a task with 3 subtasks. Context-menu → Queue subtasks sequentially. Confirm first = Queued, others = Waiting. Watch the first run to Done, confirm the second flips Queued → Running automatically.
+- Force-fail subtask 2 (cancel or make it fail). Confirm subtask 3 stays Waiting; no further dispatch.
+- Once all three are Done, confirm the planning parent auto-collapses in the list.
+- Toggle the Description chevron in the Details pane on an arbitrary task.
+- Eyeball the narrower GridSplitter — still resizable, still hittable.
+
+Automated (minimal — only where cheap):
+- Worker-level unit test for `PlanningChainCoordinator`: happy-path chain advance on Done; no advance on Failed; correct ordering by `SortOrder`.

+# Planning Session MCP via Ephemeral Worktree
+
+**Date:** 2026-04-24
+**Status:** Design approved, pending implementation plan
+**Scope:** `ClaudeDo.Worker` — planning session launch, MCP config delivery
+
+## Problem
+
+When a user starts a planning session, `claude` is spawned in the list's working directory via Windows Terminal and passed `--mcp-config <absolute-path>` pointing at a session-local `mcp.json`. In practice, the spawned `claude` session does **not** pick up the ClaudeDo MCP server: `mcp__claudedo__*` tools are not available, and no trust prompt is shown. The user has to fall back to the built-in `TaskCreate` tool, which writes nothing to ClaudeDo.
+
+The `--mcp-config` flag is documented for headless (`-p`) invocations; in interactive TUI mode it appears to be either ignored or silently dropped on at least some CLI versions. The JSON payload itself is already correct (verified against Claude Code docs — `type: "http"` + `Authorization` header is the documented form).
+
+The reliable path per Claude Code docs is project-root `.mcp.json` auto-discovery plus a one-time trust approval (or `enableAllProjectMcpServers: true`).
+
+## Goal
+
+Spawn planning sessions so that `mcp__claudedo__*` tools are available immediately, without modifying any file in the user's working directory and without requiring a trust prompt.
+
+## Non-goals
+
+- Installer-time MCP registration (rejected — loses per-session token isolation; pollutes every `claude` invocation on the machine).
+- Changing how task execution (non-planning) spawns `claude`.
+- Supporting planning on a working directory that is not a git repository.
+
+## Approach: ephemeral planning worktree
+
+Each planning session runs inside its own short-lived git worktree, created from `HEAD` of the list's working directory. The worktree is the isolated surface where we write `.mcp.json` and the settings override. The worktree is force-removed on `FinalizeAsync` / `DiscardAsync`.
+
+### Files changed
+
+- `src/ClaudeDo.Worker/Planning/PlanningSessionManager.cs`
+- `src/ClaudeDo.Worker/Planning/PlanningSessionContext.cs` (extend to carry worktree path + branch name)
+- `src/ClaudeDo.Worker/Planning/PlanningSessionFiles.cs` (may drop `McpConfigPath` if no longer used)
+- `src/ClaudeDo.Worker/Planning/WindowsTerminalPlanningLauncher.cs`
+- `src/ClaudeDo.Worker/Runner/WorktreeMaintenanceService.cs` (optional — defensive startup prune)
+- DI registration in `src/ClaudeDo.Worker/Program.cs` (inject `GitService`, `WorkerConfig`, `IDbContextFactory<ClaudeDoDbContext>` into `PlanningSessionManager`)
+
+### Data flow on `StartAsync`
+
+1. Resolve `list.WorkingDir`; hard-error if `null`, not a directory, or not a git repo (`GitService.IsGitRepoAsync`).
+2. Resolve `HEAD` via `GitService.RevParseHeadAsync`.
+3. Resolve worktree strategy from `AppSettingsRepository.GetAsync` (same resolution as `WorktreeManager.CreateAsync`):
+   - `sibling` → `<parent-of-WorkingDir>\.claudedo-worktrees\planning\<taskId>`
+   - `central` → `<CentralWorktreeRoot>\planning\<taskId>`
+   Normalize with `Path.GetFullPath`.
+4. Branch name: `claudedo/planning/<taskId-stripped-of-dashes>`.
+5. `GitService.WorktreeAddAsync(list.WorkingDir, branchName, worktreePath, baseCommit, ct)`. On `"already exists"` failure, run the same self-heal pattern as `WorktreeManager.CreateAsync` (list worktrees for branch → force-remove stale → prune → delete branch → retry once).
+6. Write into the worktree:
+   - `<worktreePath>\.mcp.json` — JSON with env-var expansion for the token (see below).
+   - `<worktreePath>\.claude\settings.local.json` — `{ "enableAllProjectMcpServers": true }` (create `.claude` dir if missing).
+7. Write session artifacts in the session directory (unchanged from today): `system-prompt.md`, `initial-prompt.txt`. The session-local `mcp.json` is no longer written — drop that write.
+8. Return `PlanningSessionStartContext` with `WorkingDir = worktreePath` and a new `WorktreePath` field (redundant with `WorkingDir` for now, but explicit for cleanup). Also carry `BranchName` so finalize/discard can delete it.
+
+### MCP JSON payload
+
+```json
+{
+  "mcpServers": {
+    "claudedo": {
+      "type": "http",
+      "url": "http://127.0.0.1:47821/mcp",
+      "headers": {
+        "Authorization": "Bearer ${CLAUDEDO_PLANNING_TOKEN}"
+      }
+    }
+  }
+}
+```
+
+The token never lives on disk in literal form — `${CLAUDEDO_PLANNING_TOKEN}` is expanded by Claude Code at load time from the spawned process's environment.
+
+### `.claude/settings.local.json` payload
+
+```json
+{
+  "enableAllProjectMcpServers": true
+}
+```
+
+Since the worktree is always empty of user customizations (fresh checkout), we write this file unconditionally. No merge / backup logic needed.
+
+### Launcher changes (`WindowsTerminalPlanningLauncher`)
+
+- `LaunchStartAsync`:
+  - Set `psi.Environment["CLAUDEDO_PLANNING_TOKEN"] = ctx.Token` (new field on `PlanningSessionStartContext`).
+  - `-d` now points at the worktree path (already handled by `ctx.WorkingDir` change).
+  - **Remove** `--mcp-config` and its path argument.
+  - Keep `--allowedTools mcp__claudedo__*,Read,Grep,Glob,WebFetch,WebSearch,Skill` — `enableAllProjectMcpServers` only handles trust, not per-tool pre-approval.
+  - Keep `--append-system-prompt-file` as the "single-value flag buffer" before the positional prompt (the existing arg-order concern is unchanged).
+- `LaunchResumeAsync`:
+  - Same env-var setup.
+  - Same `-d <worktreePath>`.
+  - **Remove** `--mcp-config` (the worktree's `.mcp.json` is discovered automatically).
+  - Keep `--resume <ClaudeSessionId>`.
+
+### Finalize / Discard
+
+`PlanningSessionManager.FinalizeAsync` and `DiscardAsync` gain:
+
+1. Look up the worktree path + branch name (deterministic from `taskId` → reuse the same resolution code as `StartAsync`).
+2. `GitService.WorktreeRemoveAsync(list.WorkingDir, worktreePath, force: true, ct)` — `--force` because claude may have created scratch files.
+3. `GitService.BranchDeleteAsync(list.WorkingDir, branchName, force: true, ct)`.
+4. Delete the session dir as today.
+
+All three steps are best-effort in `DiscardAsync` (log warnings, don't throw — the user explicitly asked to discard). `FinalizeAsync` should propagate failures, since a failed cleanup leaves resources we care about.
+
+### Resume
+
+Resume already looks up `list.WorkingDir` from the list; the worktree path is deterministic from `taskId`. `ResumeAsync` must:
+
+1. Verify the worktree directory exists; if not, hard-error ("planning session was discarded or lost — cannot resume").
+2. Return `PlanningSessionResumeContext` with `WorkingDir = worktreePath` and the token (re-read from session state — see Token persistence below).
+
+### Token persistence
+
+The token today is generated in `StartAsync` and embedded in `mcp.json` at creation time — never read again. With env-var expansion, the token must be available on **resume**. Options:
+
+- **A) Persist token to session dir** (`<sessionDir>\token`) with `FileOptions.WriteAllBytes`, restrict file ACL to current user. Read on resume.
+- **B) Store token hash in DB, raw token in memory only** — breaks across Worker restarts → no resume possible.
+
+**Chosen: A.** Token file sits inside the existing session directory (`<PlanningSessionManager._rootDirectory>\<taskId>\token`), restricted to the current user via Windows ACLs (`File.SetAccessControl` with an explicit DACL granting `FullControl` to `WindowsIdentity.GetCurrent()` only). Cleaned up in `DiscardAsync`/`FinalizeAsync` with the rest of the session dir.
+
+### Defensive startup cleanup
+
+`WorktreeMaintenanceService` already prunes worktrees tracked in the DB. Planning worktrees are **not** in the DB (they're purely filesystem-backed, keyed by `taskId` via path convention). Add a lightweight pass:
+
+- Enumerate directories matching `<root>\.claudedo-worktrees\planning\*` (for each strategy / central root we know about).
+- For each, check whether a corresponding session dir exists under `~/.todo-app/sessions/<taskId>`.
+- If no session dir: `git worktree remove --force` + `git branch -D claudedo/planning/<taskId-stripped>`.
+
+This is a small addition; if scoped too large, defer to a follow-up and accept that a crashed Worker leaves orphaned worktrees until manual cleanup.
+
+## Edge cases
+
+| Case | Behavior |
+|------|----------|
+| `list.WorkingDir` not a git repo | Hard-error on `StartAsync`. Surface message in UI. |
+| Worktree branch already exists from a prior crashed session | Self-heal: force-remove matching worktrees, prune, delete branch, retry once. (Same pattern as `WorktreeManager.CreateAsync`.) |
+| User closes Windows Terminal without clicking Finalize/Discard | Session dir + worktree remain. `ResumeAsync` works. Startup cleanup handles abandoned sessions whose session dir the user manually deletes. |
+| Claude creates/edits files in the planning worktree | Discarded with the worktree. No impact on user's real working dir. |
+| User deletes the session dir out from under the Worker | `ResumeAsync` hard-errors. Startup cleanup GCs the orphaned worktree. |
+| Two simultaneous planning sessions on the same task | Already prevented by task status transition (`Planning` is exclusive). No new consideration. |
+| `HEAD` is on a detached commit | `git worktree add` handles this fine — base commit is explicit. |
+
+## Testing
+
+Extend `tests/ClaudeDo.Worker.Tests/UiVm/TasksIslandViewModelPlanningTests.cs` (or a new file) with integration tests using the real-SQLite + real-git pattern the project already uses:
+
+- **Start happy path:** worktree dir exists after `StartAsync`, contains `.mcp.json` with `${CLAUDEDO_PLANNING_TOKEN}` literal, contains `.claude/settings.local.json` with `enableAllProjectMcpServers: true`.
+- **Finalize cleanup:** worktree dir is gone, branch is gone, session dir is gone.
+- **Discard cleanup:** same as finalize.
+- **Self-heal:** pre-create a stale branch `claudedo/planning/<id>`, then `StartAsync` must succeed.
+- **Non-git working dir:** `StartAsync` throws a specific error type.
+- **Resume after Worker restart:** seed session dir + token file, recreate `PlanningSessionManager`, `ResumeAsync` returns context pointing at the still-existing worktree.
+
+Mock `IPlanningTerminalLauncher` (already an interface) so tests don't actually spawn `wt.exe`.
+
+## Trade-offs and alternatives considered
+
+1. **Write `.mcp.json` into the user's working dir with backup/restore.** Rejected — clobber risk, file-noise on crash, user's `.gitignore` may not cover it, exposes token alongside source even with env-var expansion (because expansion is on claude's side, the raw `${VAR}` string still lives in the user's repo).
+2. **User-scope registration via installer** (`claude mcp add --scope user`). Rejected — requires a static secret baked into the Worker, loses per-session isolation, every `claude` session on the machine sees claudedo tools.
+3. **Keep `--mcp-config` and debug why it's not honored.** Rejected — even if it works on the maintainer's machine, the behavior is undocumented for interactive TUI mode, and we'd need a fallback anyway. Fixing to the documented path eliminates the uncertainty.
+
+## Open questions resolved
+
+- **WorkingDir must be a git repo?** Yes — hard-error.
+- **Worktree path strategy?** Follow the same `sibling`/`central` setting as task execution.
+- **HEAD snapshot vs WIP?** HEAD snapshot is fine — planning proposes subtasks, doesn't edit files.
+
+## Implementation sequencing
+
+A separate implementation plan (via `superpowers:writing-plans`) will break this into test-first steps.
