docs(changelog): update for v2.0.0

Interactive/streaming sessions are persistent claude.exe processes that
wait on stdin and never exit on their own. The only teardown was an
explicit StopInteractiveSession from the UI — there is no client-disconnect
or shutdown sweep — so an abandoned chat (UI closed, navigated away,
crashed) kept its claude.exe (+ conhost) alive for the worker's whole
lifetime. Under a long-running autostart worker these accumulate to dozens
of orphaned child processes.

LiveSessionRegistry now tracks per-session activity (Touch on every output
line and user action) and exposes ReapIdleAsync, which stops sessions idle
past a timeout while skipping any with a turn in flight. IdleSessionReaper
(BackgroundService) sweeps every 5 min; idle timeout defaults to 30 min,
configurable via interactive_idle_timeout_minutes (0 disables).

 - **UI-Sichtprüfung (neu, 2026-06-10, nach Refactoring-Merges):** Detail-Insel komplett durchklicken (Output/Git/Session-Tabs, Merge-Sektion, Agent-Settings-Overrides, Prep-Panel) — `DetailsIslandViewModel` wurde in Sektions-VMs aufgeteilt, Bindings angepasst. Außerdem: DiffModal-Fehler-State „Diff nicht mehr verfügbar" (Commit-Range ohne aufgezeichnete Commits) und der In-App-Konflikt-Resolver (Hub-Methoden umbenannt).
 - **UI-Sichtprüfung (neu, 2026-06-19, Rider-Style 3-Pane Merge-Editor):** Echten Konflikt auslösen (Single-Task-Approve mit Konflikt **und** Planning-Unit-Merge) und prüfen: drei Panes (Ours read-only | Result editierbar | Theirs read-only), Konfliktblöcke rot / aufgelöst grün in allen Panes, Inline-Accept `›`/`‹` in den Zwischen-Guttern landen die jeweilige Seite im Result, nur Konfliktregionen im Result editierbar (Stable read-only), synchrones vertikales Scrollen, File-Switcher bei mehreren Dateien, `M conflicts · K resolved`-Readout, Continue erst bei allen Konflikten gelöst, Binär-Guard. **Bekannte Kanten:** (1) Konflikt mit leerer Ours-Seite → Result-Region ist null-lang (Gutter via 1-Zeichen-Probe positioniert, Accept funktioniert; nur Hand-Tippen in die leere Region ist fummelig). (2) Gutter-Y nutzt `TranslatePoint` vom Result-`TextView` — bei sehr hohen Fenstern / großen Scrollständen die Ausrichtung gegenprüfen. (3) Blöcke richten sich nur über Stable-Text aus; nach einem Konflikt mit unterschiedlicher Zeilenzahl je Seite driften nachfolgende Blöcke vertikal (aligned/virtual-space Scroll ist bewusst zurückgestellt).
 - **Worker-Autostart am Gerät:** Logoff/Logon-Autostart, Update-Pfad, Uninstall entfernt die Startup-`.lnk`.
+- **In-App Interactive Sessions (neu, 2026-06-26):** ersetzt den externen `wt`-„Run interactively"-Launch durch einen In-App-Streaming-Chat (`StreamingClaudeSession`, `claude --input-format stream-json`). Real-CLI-Smoke (kein xUnit, kein Claude in Tests):
+  - Task rechtsklick → „Run interactively" startet **keinen** Terminal mehr; der Stream erscheint im Detail-Output-Tab des (selektierten) Tasks und als Monitor in Mission Control.
+  - Composer: Nachricht tippen + Enter/Send → erscheint sofort als `log-user`-Zeile in **Akzentfarbe** (via `LogKindForegroundConverter`, lokale Bindung schlägt den dim Style), Claude antwortet im selben Prozess.
+  - **Senden während Claude arbeitet = Queue (Default):** die Nachricht wird gepuffert und beim `result` des laufenden Turns abgeschickt (kein Interrupt). Mehrere Queue-Nachrichten FIFO, eine pro Turn. Gequeute Nachrichten erscheinen in einem **Pending-Streifen über der Eingabezeile** (⧗-Liste, via `InteractiveQueueChanged`); eine Nachricht landet erst im Transkript (`log-user`-Zeile via `InteractiveMessageSent`), wenn sie tatsächlich an Claude zugestellt wird. Der seeded Erst-Prompt erscheint als erste User-Zeile. Jede gequeute Zeile hat ein **✕ zum Entfernen** (`RemoveQueuedInteractiveMessage`, by-text first-match; Worker re-broadcastet die Queue).
+  - **Interrupt opt-in:** der kleine ■-Stop-Button neben Send unterbricht den laufenden Turn (`control_request`/`interrupt`, verifiziert mit CLI 2.1.191; Abbruch-`result` = `error_during_execution`, als Turn-Ende behandelt) — danach flusht die ggf. gequeute Nachricht im selben Prozess mit erhaltenem Kontext. Stop-Button ist immer sichtbar solange live (Interrupt im Idle ist ein No-op; Turn-in-flight wird nicht in die UI gebroadcastet).
+  - Session-Ende: Prozess-Exit/Stop → `InteractiveSessionEnded`, Composer verschwindet, Monitor wird „done".
+  - **Sicht-Konsistenz:** Mission-Control-Composer (SessionTerminalView-Bottom-Row mit Send-Button) vs. Detail-Composer (WorkConsole-Shell-Prompt `❯ … [Send]`) sehen unterschiedlich aus — ggf. angleichen.
+- **Drag-and-drop file attachments on the detail pane:** verify the "Drop to attach" hover overlay, drop round-trip (file appears in the list), "Add file…" picker, remove button, and that files land under `~/.todo-app/attachments/<taskId>/`. Also verify the MCP `AddTaskAttachment`/`ListTaskAttachments`/`RemoveTaskAttachment` tools and that a Running task refuses add/remove. (Manual; can't be unit-tested.)

+# Feature unification — phased plan
+
+Date: 2026-06-19
+Design: `docs/superpowers/specs/2026-06-19-feature-unification-design.md`
+
+Six slices, sequenced cheapest/lowest-risk first. Each ends green
+(`dotnet build -c Release` + the touched test project) and is independently
+committable. Phases 0–1 are detailed here; 2–5 are scoped, and each gets its own
+`docs/superpowers/plans/2026-06-19-unify-<slice>.md` when picked up (per the
+2026-06-05 layer-A/B/C convention). Build per-csproj (`-c Release`) — `.slnx` needs
+.NET 9 and a running Worker locks `Debug`.
+
+---
+
+## Phase 0 — Groundwork (Bucket C). No UX change.
+
+**0a. Delete the dead hunks conflict API (C1).**
+- Remove `TaskMergeService.GetConflictsAsync` + the `MergeConflicts`/`ConflictFileContent` records it returns (`src/ClaudeDo.Worker/Lifecycle/TaskMergeService.cs:250`) if unused elsewhere.
+- Remove `WorkerHub.GetMergeConflicts` (`src/ClaudeDo.Worker/Hub/WorkerHub.cs:378`) + `MergeConflictsDto`/`ConflictFileDto`/`ConflictHunkDto` if unused.
+- Remove `WorkerClient`'s `"GetMergeConflicts"` invoke (`src/ClaudeDo.Ui/Services/WorkerClient.cs:276`) + the `IWorkerClient` member + every fake override (`tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs`, `TasksIslandViewModelPlanningTests.cs`, others — grep `GetMergeConflicts`).
+- Delete `TaskMergeServiceTests.cs:672` `GetConflictsAsync_AfterConflictMerge_ReturnsOursAndTheirs`.
+- Verify with grep first: `GetConflictsAsync` and `GetMergeConflicts` have **no** callers outside this chain + tests.
+- Acceptance: Worker + Ui build; Worker.Tests + Ui.Tests green; `GetMergeConflictDocuments` path untouched.
+
+**0b. Single task-creation path (C2).**
+- Identify the path MCP `ExternalMcpService.AddTask` uses; expose a thin creation method (repository or a small `TaskCreationService`) that applies the same defaults (ListId, SortOrder, CreatedAt).
+- Re-point `TasksIslandViewModel.AddAsync` at it instead of `db.Tasks.Add` direct EF.
+- Acceptance: quick-add still works; one creation path; Ui.Tests + Worker.Tests green.
+
+**0c. Prune stale worktrees (C3).**
+- `git worktree list`; remove the orphaned `.claude/worktrees/*` entries (confirm each is unwanted with Mika before `git worktree remove`).
+- Acceptance: only intended worktrees remain; no tracked files change.
+
+> C4 (naming alignment) intentionally NOT in this phase — see design.
+
+---
+
+## Phase 1 — DialogService (B3–B5). Low–medium.
+
+**Goal:** one `IDialogService` replaces the scattered `Show*` Func seams and the
+duplicate open-commands.
+
+- New `IDialogService` (Ui/Services) with typed methods: `OpenListSettings(ListNavItemViewModel)`, `OpenRepoImport()`, `OpenWorktreesOverview(string? listId)`, `OpenWeeklyReport()`, `OpenAbout()`, `OpenWorkerConnectionHelp()`. Implementation owns the factories + `ModalShell`/TCS wiring currently in `MainWindow.axaml.cs` + `IslandsShellViewModel.cs:59-71`.
+- Inject it into `ListsIslandViewModel`, `TasksIslandViewModel`, `IslandsShellViewModel`. Collapse the three List-Settings doors (Lists context menu, Tasks header, shell bridge `IslandsShellViewModel.cs:190-194`) to one `dialogs.OpenListSettings(row)` call; same for Repo Import (2→1) and Worktrees Overview (2→1, keep the `listId?` param for global-vs-per-list).
+- Keep `ModalShell`/TCS dialog pattern; this only centralizes *opening*.
+- Update fakes/ctors per the IWorkerClient-fakes hazard (ctor changes ripple to Ui.Tests).
+- Acceptance: every dialog opens via one method; no duplicate open-commands; Ui.Tests green; visual gap flagged (open each dialog from each former door).
+
+---
+
+## Phase 2 — MergeCoordinator (B1). Medium.
+
+**Goal:** delete the five `RequestConflictResolution` seams; one coordinator.
+
+- New `IMergeCoordinator` (Ui) `MergeAsync(taskId, targetBranch)` = the body of `IslandsShellViewModel.RequestConflictResolutionAsync` (`:49`) plus the "open MergeModal → on conflict open resolver" flow currently split across `MergeModalViewModel:108` and `DiffModalViewModel:103`.
+- Remove the `Func<string,string,Task>? RequestConflictResolution` from `WorktreesOverviewModalViewModel:83`, `DiffModalViewModel:75`, `MergeModalViewModel:33`, `MergeSectionViewModel:51`, and the `DetailsIslandViewModel:347` delegate; inject the coordinator instead.
+- Re-point doors: review Approve, Diff Merge button, WorktreesOverview single + batch (`:331`), Details merge section.
+- Update seam tests (`WorktreesOverviewBatchMergeTests.cs:145`, `DetailsIslandConflictSeamTests.cs:84`) to assert via the coordinator.
+- Acceptance: one merge entry API; resolver still opens for single-task AND planning conflict; Ui.Tests green; visual gap flagged (force a conflict from Approve and from the Diff Merge button).
+
+---
+
+## Phase 3 — WorktreeActions (A3). Medium.
+
+**Goal:** one per-task worktree-actions VM reused by overview rows + Details.
+
+- New `WorktreeActionsViewModel(taskId)` with Merge/Diff/Discard/Keep/ForceRemove over `IWorkerClient` (uses the Phase-2 coordinator for Merge, the Phase-5 viewer for Diff — until then, current calls).
+- `WorktreesOverviewModalViewModel` rows compose one each; `MergeSectionViewModel` hosts one for the active task. Remove the duplicated commands.
+- Acceptance: both surfaces drive the same VM; Ui.Tests green; visual gap flagged.
+
+---
+
+## Phase 4 — AgentConfigEditor (A2). Medium.
+
+**Goal:** one config editor for Global | List | Task scope.
+
+- New `AgentConfigEditorViewModel(scope)` over `InheritanceResolver` exposing Model/SystemPrompt/AgentPath/MaxTurns + reset commands + `InheritedBadge` state; persists via the scope's hub method (`UpdateListConfig` / `UpdateTaskAgentSettings` / app settings).
+- Embed in `SettingsModalViewModel`, `ListSettingsModalViewModel`, and the Details `AgentSettingsSectionViewModel` host; delete the duplicated field/reset logic.
+- Acceptance: identical editor in all three scopes; Localization parity; Ui.Tests green; visual gap flagged.
+
+---
+
+## Phase 5 — DiffViewer (A1 + B2). High; last.
+
+**Goal:** one diff component replaces DiffModal + WorktreeModal + PlanningDiff.
+
+- New `DiffViewerViewModel` with `DiffSource` enum/abstraction (`DirtyWorktree | BranchVsBase | CommitRange | PlanningAggregate | IntegrationBranch`) and an optional file-tree pane (port `WorktreeModal`'s tree + Avalonia-12 selection workaround); reuse `UnifiedDiffParser` + `DiffLinesView`; keep PlanningDiff's combined-mode toggle as a source switch.
+- Re-point all B2 doors to open it with the right source. Remove the three old VMs/views.
+- Update `DiffModalViewModelTests`, `PlanningDiffViewModelTests`.
+- Acceptance: every diff door opens the one viewer; whole-unified AND file-tree layouts work; Ui.Tests green; visual gap flagged (worktree-dirty, post-merge commit-range, planning per-subtask + integration).
+
+---
+
+## Sequencing rationale
+
+0 (delete/no-UX) → 1 (isolated, unblocks nothing but cheap) → 2 (coordinator; 3 & 5
+lean on it for Merge/Diff) → 3 → 4 (independent) → 5 (biggest, most UX-sensitive,
+benefits from 2's coordinator). Stop after any phase and the app is shippable.
+
+## Per-phase commits
+
+Conventional Commits, one per phase (or per sub-step in Phase 0): e.g.
+`refactor(merge): single MergeCoordinator replaces 5 conflict seams`. Stage by path
+(never `git add -A` — concurrent sessions). Commit the spec + this plan first.

+# Phase 4 — AgentConfigEditor (A2)
+
+Date: 2026-06-23 (picked up after reordering Phase 3 ↔ 4)
+Umbrella: `docs/superpowers/plans/2026-06-19-feature-unification-plan.md`
+Design: `docs/superpowers/specs/2026-06-19-feature-unification-design.md` (A2)
+
+## Reordering note
+
+Phase 3 (WorktreeActions) was deferred. Its premise — overview rows and the Details
+merge section each owning duplicate worktree commands — only half-holds: Details has
+no Discard/Keep/ForceRemove, and the two Diff doors open different VMs (`WorktreeModal`
+vs `DiffModal`) that only Phase 5 unifies. So Phase 3's clean form depends on Phase 5
+(Diff) and a fuller MergeCoordinator (Merge); doing it now would build throwaway
+per-surface delegates. **Phase 3 is folded into Phase 5.** Phase 4 (independent, clean
+dedup) runs now.
+
+## Scope decision: List + Task only (global left as-is)
+
+The design names three scopes (Global | List | Task). Verified against the tree on
+2026-06-23, only **List and Task genuinely duplicate**:
+
+- **List** (`ListSettingsModalViewModel`, "AGENT" section): Model / MaxTurns /
+  SystemPrompt / AgentFile, each with `InheritedBadge` + `↺` reset; 2-tier
+  (list→global) badges computed with inline logic (does **not** use the existing
+  `InheritanceResolver.ResolveList` — which is currently dead code); explicit Save.
+- **Task** (`AgentSettingsSectionViewModel`, TaskHeaderBar gear flyout): same four
+  fields; 3-tier (task→list→global) badges via `InheritanceResolver.Resolve`;
+  `EffectiveMaxTurns` + `EffectiveSystemPromptHint`; `IsRunning` gate; debounced
+  auto-save.
+
+**Global** (`GeneralSettingsTabViewModel`, Settings → General) is the root: no
+inheritance, no badges, no agent file, no reset — three plain controls (model combo,
+max-turns numeric, instructions textbox) plus a global-only PermissionMode, interleaved
+with unrelated settings (Language, parallelism, report paths, standup weekday) and
+saved batched into one `AppSettingsDto` via the modal Save. Embedding the shared editor
+there buys ~3 plain fields at the cost of a degenerate no-badges/no-agent/no-reset mode
+plus surgery on the settings save path and a relayout of the most settings-dense view.
+**Not worth it — global stays as-is.** (Confirmed with Mika 2026-06-23.)
+
+The real maintenance hazard is the **VM logic** (two copies of badge/reset/inheritance
+that already drifted), and the **view** (3 of 4 field blocks are pixel-identical). Both
+collapse cleanly for List+Task.
+
+## Target
+
+One `AgentConfigEditorViewModel` + one `AgentConfigEditor` UserControl, instantiated
+per surface with a scope. The two host VMs keep only their non-agent concerns and host
+the editor as a child.
+
+### `ViewModels/Agent/AgentConfigEditorViewModel.cs` (new)
+
+- `enum AgentConfigScope { List, Task }`
+- ctor `(IWorkerClient worker, AgentConfigScope scope)`
+- Unified bindable surface (single names both views bind to):
+  `Model` (string?), `MaxTurns` (decimal?), `SystemPrompt` (string),
+  `SelectedAgent` (AgentInfo?); `ModelOptions`, `Agents`;
+  `ModelBadge`/`TurnsBadge`/`AgentBadge`, `ModelInheritedHint`/`TurnsInheritedHint`,
+  `EffectiveSystemPromptHint`; `EffectiveMaxTurns` (int), `IsRunning`/`IsEnabled`.
+- Reset commands: `ResetModel`, `ResetTurns`, `ResetAgent`, `ResetAll`.
+- Badges via `InheritanceResolver`: scope==Task → `Resolve(own, list, global)`;
+  scope==List → `ResolveList(own, global)` (adopts the dead method). One `BadgeFor`
+  helper covers both (List scope never yields the `List` source).
+- Load: `LoadForListAsync(listId)` and `LoadForTaskAsync(TaskEntity entity)` — both
+  pull agents + app-settings (global defaults); Task also pulls the list tier +
+  `EffectiveSystemPromptHint`. Localizer-change re-badges (port the `Loc.LanguageChanged`
+  handler + `IDisposable`).
+- Save: `SaveAsync()` is scope-aware — List builds `UpdateListConfigDto` →
+  `UpdateListConfigAsync`; Task builds `UpdateTaskAgentSettingsDto` →
+  `UpdateTaskAgentSettingsAsync`. Task scope also auto-saves debounced (300ms) on field
+  changes; List does not (the modal Save button calls `SaveAsync`). `SaveAsync` is
+  directly callable (tests bypass the debounce).
+- Task-only `Clear()` + `TaskId`.
+
+### `Views/Controls/AgentConfigEditor.axaml` (+ .axaml.cs) (new)
+
+- `x:DataType` = `AgentConfigEditorViewModel`; host sets `DataContext="{Binding Agent}"`.
+- The four field blocks (model/turns/systemprompt/agent) with `InheritedBadge` + `↺`
+  reset, lifted verbatim from the existing two views (they already match). Agent combo
+  shows Name + Description (both scopes; harmless for task). `EffectiveSystemPromptHint`
+  line gated on non-empty (hides for List).
+- `StyledProperty<bool> ShowAgentBrowse` (default false). True → render the Browse
+  button + path line; the browse file-picker code-behind lives here (moved from
+  `ListSettingsModalView`).
+- Shared localization namespace `settings.agentEditor.*` (model/maxTurns/systemPrompt/
+  agentFile/promptPrepended). Reset tooltip reuses `settings.inherit.resetToInherited`.
+
+### Re-point hosts
+
+- `ListSettingsModalViewModel`: drop the agent fields/badges/resets/option-lists; add
+  `public AgentConfigEditorViewModel Agent { get; }` (scope=List). `LoadAsync` →
+  `Agent.LoadForListAsync(listId)`. `SaveAsync` keeps `UpdateListAsync` (name/dir) and
+  adds `await Agent.SaveAsync()`. Keep working-dir browse (`BrowseClicked`).
+- `ListSettingsModalView.axaml`: replace the AGENT section body with
+  `<ctl:AgentConfigEditor DataContext="{Binding Agent}" ShowAgentBrowse="True"/>`; the
+  section-header "Reset agent settings" button binds `Agent.ResetAllCommand`. Remove the
+  agent browse code-behind (moved into the control).
+- `DetailsIslandViewModel`: `AgentSettings` becomes `AgentConfigEditorViewModel`
+  (scope=Task). Preserve the call sites: ctor, `EffectiveMaxTurns`→`TurnsText`
+  PropertyChanged hook, `IsRunning` push, `Dispose`, `Clear`, `TaskId`,
+  `LoadForTaskAsync(entity, ct)`.
+- `TaskHeaderBar.axaml`: replace the flyout field blocks with
+  `<ctl:AgentConfigEditor DataContext="{Binding AgentSettings}"/>` (ShowAgentBrowse=false).
+  Keep the gear button + heading.
+- Delete `AgentSettingsSectionViewModel.cs`.
+
+## Tests
+
+- New `tests/ClaudeDo.Ui.Tests/ViewModels/AgentConfigEditorViewModelTests.cs`:
+  - List scope: badges resolve override-vs-global; resets clear; `SaveAsync` builds the
+    right `UpdateListConfigDto` (via `StubWorkerClient`).
+  - Task scope: badges resolve override/list/global; `EffectiveMaxTurns`/
+    `EffectiveSystemPromptHint` from list tier; resets clear; `SaveAsync` builds the right
+    `UpdateTaskAgentSettingsDto`.
+- `InheritanceResolverTests` unchanged (resolver untouched).
+- Existing DetailsIsland* tests must stay green (they construct the VM but don't name the
+  moved members).
+
+## Acceptance
+
+- `dotnet build -c Release` clean for Ui (+ App).
+- `Ui.Tests` + `Localization.Tests` green.
+- One editor VM + one control drive both List and Task; duplicated field/badge/reset
+  logic deleted; `ResolveList` now has a real caller.
+- Visual gap flagged: open List Settings → Agent, and a task's gear flyout — verify
+  badges, ↺ resets, reset-all, agent browse (list only), system-prompt hint (task), and
+  that list Save persists + task auto-saves.
+
+## Commit
+
+`refactor(agent-config): single AgentConfigEditor for list + task scopes`. Stage by
+path. Commit this plan with it.

+# Phase 5 — DiffViewer (A1 + B2)
+
+Date: 2026-06-23
+Umbrella: `docs/superpowers/plans/2026-06-19-feature-unification-plan.md`
+Design: `docs/superpowers/specs/2026-06-19-feature-unification-design.md` (A1, B2)
+
+## Goal
+
+One diff component replaces the three parallel read-only diff windows:
+`DiffModalViewModel`/View, `WorktreeModalViewModel`/View, `PlanningDiffViewModel`/View.
+**Merge editor (`ConflictResolverViewModel`) is untouched** — per the design's hard
+decision; the viewer only *opens* it on conflict via the existing Merge flow.
+
+All three are already master-detail: **left nav pane + right `DiffLinesView`**. They
+differ only in left-pane content, chrome, and data source — so they collapse into one
+shell with a source mode.
+
+## Decisions (Mika, 2026-06-23)
+
+- **File nav = file-tree** (folder-grouped), not a flat list. Port `WorktreeModal`'s tree
+  + the Avalonia-12 `TreeView.SelectionChanged` workaround. Carry per-file status + +adds/
+  −dels into the tree rows (from the parsed `DiffFileViewModel`).
+- Planning keeps its **subtask-list + combined-mode toggle**; the branch source keeps its
+  **Merge** button.
+
+## Target
+
+### Shared types → `ViewModels/Modals/DiffModels.cs` (new, same namespace)
+
+Move out of the to-be-deleted VMs so `UnifiedDiffParser`/`DiffLinesView` keep compiling:
+`DiffLineKind`, `DiffFileStatus`, `DiffLineViewModel`, `DiffFileViewModel` (from
+`DiffModalViewModel.cs`), `SubtaskDiffRow` (from `PlanningDiffViewModel.cs`). Add new
+`DiffTreeNodeViewModel` (dir/file node; file leaves hold their `DiffFileViewModel`).
+
+### `DiffViewerViewModel` (`ViewModels/Modals/DiffViewerViewModel.cs`, new)
+
+ctor `(GitService git, IWorkerClient worker)`. A `DiffViewerMode { Files, Planning }`.
+
+- **File sources** (replaces DiffModal + WorktreeModal): config props `WorktreePath`,
+  `BaseRef`, `HeadCommit`, `FromCommitRange`, `TaskId`, `TaskTitle` + `ShowMergeModal`/
+  `ResolveMergeVm` delegates. `LoadAsync` pulls the whole diff via GitService
+  (`GetCommitRangeDiffAsync` | `GetBranchDiffAsync` | `GetDiffAsync`), parses with
+  `UnifiedDiffParser.Parse`, builds `FileTree`. `SelectedNode` (leaf) → `SelectedFile`
+  (header + binary/empty placeholders + `Lines`). Commit-range null-guard → "no longer
+  available" (preserve DiffModal behavior). `MergeCommand` (CanMerge = TaskId +
+  delegates) opens the MergeModal, closes on merged/routed (verbatim from DiffModal).
+- **Planning source** (replaces PlanningDiff): config `PlanningTaskId`, `TargetBranch`.
+  `LoadAsync` pulls `GetPlanningAggregateAsync` → `Subtasks`; `SelectedSubtask` →
+  `DisplayedDiff`; `IsCombinedMode` toggle → `BuildPlanningIntegrationBranchAsync`
+  (success → combined diff; conflict → `CombinedWarning` with subtask + file count;
+  null → hub-error warning). `DisplayedDiff` → flattened `DiffLines` (right pane).
+- Shared: `StatusMessage`, `CloseAction`, `CloseCommand`.
+
+### `DiffViewerView` (`Views/Modals/DiffViewerView.axaml` + `.cs`, new)
+
+`ModalShell`-based window. Left pane: `TreeView` (Files mode) or subtask `ListBox`
+(Planning mode), toggled by mode. Right pane: the DiffModal file pane (header + binary/
+empty/no-changes placeholders + `DiffLinesView Lines="SelectedFile.Lines"`) in Files mode,
+or `DiffLinesView Lines="DiffLines"` in Planning mode. Toolbar: combined toggle + warning
++ loading (Planning). Footer: Merge button (Files mode, CanMerge). Code-behind: `CloseAction`,
+the `TreeView.SelectionChanged` → `SelectedNode` workaround, dir-row tap-to-expand.
+
+### Re-point the 3 doors → one viewer
+
+- **`MergeSectionViewModel`**: `OpenDiffAsync` builds a Files-mode `DiffViewerViewModel`
+  (+ ShowMergeModal/ResolveMergeVm) and calls a single `ShowDiffViewer` delegate;
+  `ReviewCombinedDiffAsync` builds a Planning-mode one and calls the *same* delegate.
+  Replaces `ShowDiffModal` + `ShowPlanningDiffModal` with one `Func<DiffViewerViewModel,Task>
+  ShowDiffViewer`; keeps `ShowMergeModal`. (Resolve the VM via `_services`.)
+- **`DetailsIslandView.axaml.cs`**: replace the two `ShowDiffModal`/`ShowPlanningDiffModal`
+  wirings (→ `DiffModalView`/`PlanningDiffView`) with one `ShowDiffViewer` (→ `DiffViewerView`).
+  Keep `ShowMergeModal`.
+- **`WorktreesOverviewModalViewModel`**: `ShowDiff` builds a Files-mode viewer (worktree path
+  + base). Change `_diffVmFactory` from `Func<WorktreeModalViewModel>` to
+  `Func<DiffViewerViewModel>`; `ShowDiffAction` stays `Action<DiffViewerViewModel>`.
+- **`WindowDialogService.cs`**: `ShowDiffAction` → `new DiffViewerView` + `LoadAsync` + show.
+- **`Program.cs`**: register `DiffViewerViewModel` (transient) + `Func<DiffViewerViewModel>`;
+  drop the `WorktreeModalViewModel` registration.
+
+### Delete
+
+`DiffModalViewModel.cs`, `WorktreeModalViewModel.cs`, `PlanningDiffViewModel.cs`,
+`DiffModalView.axaml(.cs)`, `WorktreeModalView.axaml(.cs)`, `PlanningDiffView.axaml(.cs)`.
+
+### Localization
+
+Reuse existing keys in the merged view (`modals.diff.*` for the file pane, `planning.diff.*`
+for the planning toolbar). Prune clearly-orphaned `modals.worktree.*` if trivial; keep en/de
+parity.
+
+## Tests
+
+Replace `DiffModalViewModelTests` + `PlanningDiffViewModelTests` with
+`DiffViewerViewModelTests` preserving the behaviors: commit-range null-guard → unavailable;
+planning init populates + selects first; subtask select → DisplayedDiff; combined toggle
+success/conflict/null. `WorktreesOverviewBatchMergeTests` compiles unchanged (`() => null!`
+satisfies the new Func type). `UnifiedDiffParserTests` unchanged.
+
+## Acceptance
+
+- `dotnet build -c Release` clean (App); `Ui.Tests` + `Localization.Tests` green.
+- One viewer reached from all 3 doors; old VMs/views deleted; merge editor untouched.
+- Visual gap flagged: Details "Open Diff" (dirty + post-merge commit-range), Worktrees-
+  Overview "Show Diff" (tree), Details "Review Combined Diff" (subtasks + combined toggle),
+  and the Merge button still opens the merge form / resolver on conflict.
+
+## Commit
+
+`refactor(diff): single DiffViewer replaces DiffModal + WorktreeModal + PlanningDiff`.
+Stage by path (exclude concurrent peers' files). Then Phase 3 (WorktreeActions) follows as
+its own slice, reusing this viewer.

+# Plan — Worker log → footer + Log Visualizer overlay
+
+Design: `docs/superpowers/specs/2026-06-23-worker-log-footer-overlay-design.md`. Build on `main`, TDD, commit per task (Conventional Commits, explicit paths — shared worktree). Build `-c Release`.
+
+## Task 1 — `LogRingBuffer` (Worker) + tests
+- `src/ClaudeDo.Worker/Logging/WorkerLogRecord.cs` — `record WorkerLogRecord(string Message, WorkerLogLevel Level, DateTime TimestampUtc)`.
+- `src/ClaudeDo.Worker/Logging/LogRingBuffer.cs` — thread-safe, `TimeSpan window` + int cap; `Append(record)`, `Snapshot()`. Uses an injected clock func (`Func<DateTime>`) for testability (default `() => DateTime.UtcNow`).
+- Tests: age eviction, cap eviction, snapshot order. **No `DateTime.UtcNow` in tests — drive the clock.**
+
+## Task 2 — `BroadcastLogSink` (Worker) + tests
+- `src/ClaudeDo.Worker/Logging/BroadcastLogSink.cs : ILogEventSink` — level map, render (+exception first line), append-all-levels, broadcast Warn/Err via deferred `HubBroadcaster` (`Attach`), dedupe window (const 120s), loop-guard (skip SignalR `SourceContext` for broadcast; swallow broadcast exceptions). Inject clock func.
+- Broadcaster is an abstraction the test can fake: depend on a tiny `Func<string,WorkerLogLevel,DateTime,Task>?` set by `Attach`, OR on `HubBroadcaster` directly (it's a sealed class — prefer a delegate to keep the test pure). Use a delegate.
+- Tests: all levels buffered; only Warn/Err invoke the broadcast delegate; dedupe suppresses 2nd identical within window but still buffers; exception rendering; SignalR-source event buffered but not broadcast.
+
+## Task 3 — wire into `Program.cs` + `WorkerHub.GetRecentLogs`
+- `Program.cs`: create `LogRingBuffer` + `BroadcastLogSink` locals before build; `.WriteTo.Sink(broadcastSink)`; `AddSingleton(logBuffer)`; after build `broadcastSink.Attach((m,l,t) => broadcaster.WorkerLog(m,l,t))` using resolved `HubBroadcaster`.
+- `WorkerHub`: inject `LogRingBuffer`; `public IReadOnlyList<WorkerLogRecordDto> GetRecentLogs()` → snapshot mapped to DTO. Add `WorkerLogRecordDto` (Hub or shared). Update `WorkerHub` ctor → check hub-construction call sites/tests.
+- Build Worker `-c Release`; run Worker.Tests (filtered to new + hub).
+
+## Task 4 — `IWorkerClient.GetRecentLogsAsync` + WorkerClient + fakes
+- `IWorkerClient` + `WorkerClient` impl (`_hub.InvokeAsync<List<WorkerLogEntry>>("GetRecentLogs", ct)`).
+- Update fakes: `tests/ClaudeDo.Ui.Tests/StubWorkerClient.cs`, Worker.Tests UiVm fake(s) → return `Array.Empty<WorkerLogEntry>()`.
+- Build Ui + Worker.Tests.
+
+## Task 5 — `LogVisualizerViewModel` + View + dialog wiring + tests
+- VM (Modals/), View (Modals/, ModalShell), `IDialogService.ShowLogVisualizerAsync` + `WindowDialogService` impl.
+- `IslandsShellViewModel.OpenLogVisualizerCommand` (resolves VM, loads, shows). Make footer worker-log line a clickable Button → command.
+- Localization `vm.logVisualizer` en+de.
+- Tests: VM load/populate/filter. Build App `-c Release`; Ui.Tests + Localization.Tests.
+
+## Task 6 — verify + docs
+- Full relevant test pass. Update `src/ClaudeDo.Ui/CLAUDE.md` (overlay VM/view, footer click) + `src/ClaudeDo.Worker/CLAUDE.md` (Logging/ folder, sink, GetRecentLogs, WorkerLog now carries Serilog Warn/Err). Note visual-verification gap (overlay render) for the user.

+# Plan — Interactive "Answer Claude's Questions"
+
+Spec: `docs/superpowers/specs/2026-06-25-interactive-ask-user-design.md`
+
+Implement on the shared main tree. Commit explicit paths per task (never `git add -A`).
+Build with `-c Release` (running Worker locks Debug). No real-Claude tests.
+
+## Task 1 — PendingQuestionRegistry (worker, new file)
+- `src/ClaudeDo.Worker/Runner/PendingQuestionRegistry.cs`: singleton; `record PendingQuestion(TaskId, QuestionId, Question)`.
+  - `(string QuestionId, Task<string> Answer) Register(taskId, question)` — overwrites any stale entry, `RunContinuationsAsynchronously`.
+  - `bool TryAnswer(taskId, questionId, answer)`; `PendingQuestion? Get(taskId)`; `void Remove(taskId, questionId)`.
+- Test: `tests/ClaudeDo.Worker.Tests/Runner/PendingQuestionRegistryTests.cs` — register→answer resolves the task; wrong questionId no-ops; Get reflects state; second Register overwrites.
+
+## Task 2 — AskUser MCP tool (worker)
+- `TaskRunMcpService.cs`: inject `PendingQuestionRegistry`; add
+  `[McpServerTool] async Task<string> AskUser(string question, CancellationToken ct)`:
+  - caller id from `_ctx.Current.CallerTaskId`; register; broadcast `TaskQuestionAsked`.
+  - await answer via `Task<string>.WaitAsync` with a 3-min linked-CTS; on timeout return the fallback string; on request-cancel rethrow.
+  - `finally`: `Remove` + broadcast `TaskQuestionResolved`.
+  - `[Description]`: when to use (only when a wrong guess is costly/irreversible; otherwise proceed).
+- Test: `tests/ClaudeDo.Worker.Tests/Runner/AskUserToolTests.cs` — answer path returns the answer; timeout path returns fallback (inject a short timeout or a seam) with a fake broadcaster + stub context accessor.
+
+## Task 3 — Wire MCP for all runs + timeout env (worker)
+- `TaskRunner.RunAsync`: move MCP-identity setup out of the `standalone` gate so every run gets `claudedo_run`; `AllowedTools` = `mcp__claudedo_run__AskUser` always, append `,mcp__claudedo_run__SuggestImprovement` when standalone. Keep token cleanup in `finally`.
+- `ClaudeProcess.cs`: `psi.Environment["MCP_TOOL_TIMEOUT"] = "200000";`.
+- System prompt file (PromptKind.System default): add one guidance line about `AskUser`.
+
+## Task 4 — Hub + Broadcaster (worker)
+- `HubBroadcaster.cs`: `TaskQuestionAsked(taskId, questionId, question)`, `TaskQuestionResolved(taskId, questionId)`.
+- `WorkerHub.cs`: inject registry; `bool AnswerTaskQuestion(taskId, questionId, answer)`; `PendingQuestionDto? GetPendingQuestion(taskId)`; `record PendingQuestionDto(...)`.
+- `Program.cs`: register `PendingQuestionRegistry` as singleton.
+
+## Task 5 — UI client (IWorkerClient/WorkerClient + fakes)
+- `IWorkerClient`: `Task AnswerTaskQuestionAsync(taskId, questionId, answer)`, `Task<PendingQuestionDto?> GetPendingQuestionAsync(taskId)`, events `Action<string,string,string>? TaskQuestionAskedEvent`, `Action<string,string>? TaskQuestionResolvedEvent`; UI DTO record.
+- `WorkerClient`: implement invokes + `On<...>` handlers raising the events.
+- Update hand-rolled `IWorkerClient` fakes in Ui.Tests (and Worker.Tests if present).
+
+## Task 6 — TaskMonitorViewModel (hot file)
+- Subscribe both events (filter by `_subscribedTaskId`); dispose handlers.
+- Props: `PendingQuestionId`, `PendingQuestion`, `HasPendingQuestion`, `AnswerDraft`, `IsWaitingForInput`.
+- `SubmitAnswerCommand` (CanExecute: non-empty draft + HasPendingQuestion) → `AnswerTaskQuestionAsync`; clear draft.
+- Clear pending on `TaskFinished` for this task and in `Reset()`.
+- Test: `TaskMonitorViewModelTests` — asked event surfaces question; submit invokes client + clears; resolved/finished clears.
+
+## Task 7 — Hydrate on attach (MissionControlViewModel)
+- In `HydrateAsync`, after `ApplyState`, call `GetPendingQuestionAsync(taskId)`; if present, set the monitor's pending question (re-attach case).
+
+## Task 8 — View banner (hot file, additive)
+- `MonitorPaneView.axaml`: a `Border DockPanel.Dock="Top"` above `SessionTerminalView`, `IsVisible="{Binding HasPendingQuestion}"`, showing the question text, a `TextBox` bound to `AnswerDraft` (Enter submits), and a Send `Button` → `SubmitAnswerCommand`. Mirror the roadblock-banner styling.
+
+## Task 9 — Localization
+- `en.json` + `de.json`: `missionControl.question.title`, `.placeholder`, `.send`. Keep parity (Localization.Tests).
+
+## Task 10 — Build + test + verify
+- `dotnet build` App + Worker `-c Release`; run Worker.Tests, Ui.Tests, Localization.Tests.
+- Self-review diffs. Flag the two manual verification gaps to Mika. Do not push.

+# Plan — Mission Control (multi-task live monitoring)
+
+Spec: `docs/superpowers/specs/2026-06-25-mission-control-design.md`
+
+Execution: subagent-driven, **sonnet** model, TDD where a test is meaningful, build + test before
+each commit, one Conventional Commit per task. Stage files explicitly by path (never `git add -A`).
+**No duplication** — every task reuses the assets named in the spec's reuse map.
+
+---
+
+## Phase 1 — Extract the reusable monitor core (no behavior change)
+
+### Task 1.1 — Move `LogLineViewModel` + `LogKind` to their own file
+- Cut `LogKind` enum and `LogLineViewModel` from `DetailsIslandViewModel.cs` into
+  `ViewModels/Islands/LogLineViewModel.cs` (same namespace). No logic change.
+- Build `ClaudeDo.App`; run Ui.Tests. Commit: `refactor(ui): split LogLineViewModel into own file`.
+
+### Task 1.2 — Create `TaskMonitorViewModel` owning the streaming/status/outcome core
+- New `ViewModels/Islands/TaskMonitorViewModel.cs`. Move from `DetailsIslandViewModel`:
+  `Log`, `_subscribedTaskId`, `_formatter`, `_claudeBuf`, `OnTaskMessage`, `AppendStdoutLine`,
+  `FlushClaudeBuffer`, `ReplayLogFileAsync`, `ExpandUserPath`; `AgentState` + all `Is*` flags +
+  `OnAgentStateChanged`; `StatusToStateKey` / `FinishedStatusToStateKey`; `SessionOutcome` /
+  `Roadblocks` + `ApplyOutcome` + `RoadblockMarker`; the worker `TaskMessage/Started/Finished/Updated`
+  subscriptions for the streaming concern; `Title`/`TaskIdBadge`/`Model`/`TurnsText`/`TokensFormatted`/
+  diff text/elapsed; `BlockingReason` (+visible flag) from `BlockedByTaskId`/review/children/roadblocks.
+- Ctor takes `IDbContextFactory<ClaudeDoDbContext>`, `IWorkerClient`. `Attach(taskId)` /
+  `AttachAsync(entity)` to (re)bind + replay; `IDisposable` unsubscribes (mirror existing Dispose).
+- Unit test (Ui.Tests): feed `[stdout]`/`[claude]`/`[tool]` lines via the worker fake → `Log`
+  accumulates correctly; `TaskFinished` flips `AgentState`; `ApplyOutcome` splits the roadblock marker.
+  Reuse the existing IWorkerClient fake (see `iworkerclient_fakes_sync`).
+- Build + test. Commit: `feat(ui): extract TaskMonitorViewModel streaming core`.
+
+### Task 1.3 — `DetailsIslandViewModel` delegates to `Monitor`
+- Add `public TaskMonitorViewModel Monitor { get; }`; construct it; route `Bind`/`BindAsync` to
+  `Monitor.Attach`. Remove the moved members; keep subtasks/attachments/editing/merge/review/child
+  outcomes/notes/prep intact. Dispose `Monitor`.
+- Repoint `WorkConsole.axaml` Output-tab bindings (`Log`, `IsRunning/IsDone/IsFailed`,
+  `SessionOutcome`, `TurnsText`, `DiffAddText`/`DiffDelText`, `Model`) to `Monitor.*`. Leave
+  review/merge/session bindings unchanged.
+- Build + test. **Manual visual pass: Details pane behaves exactly as before** (flag for Mika).
+  Commit: `refactor(ui): route DetailsIsland streaming through Monitor`.
+
+---
+
+## Phase 2 — Mission Control window
+
+### Task 2.1 — `MissionControlViewModel`
+- New `ViewModels/MissionControlViewModel.cs`: `ObservableCollection<TaskMonitorViewModel> Monitors`
+  keyed by id; seed from `GetActive()`; add on `TaskStarted`, flip-state-and-keep on `TaskFinished`;
+  `ClearFinished` command; `ColumnCount`/layout signal from `Monitors.Count`; least-active collapse.
+  `IDisposable` disposes all monitors. Inject `IDbContextFactory`, `IWorkerClient`, `IServiceProvider`.
+- Register `AddSingleton<MissionControlViewModel>` in `App/Program.cs`.
+- Unit test: simulate two `TaskStarted` → two monitors; `TaskFinished` keeps the pane; `ColumnCount`
+  matches count. Commit: `feat(ui): add MissionControlViewModel`.
+
+### Task 2.2 — `RevealTaskAsync` navigation on the shell
+- Add `IslandsShellViewModel.RevealTaskAsync(taskId)` (resolve list → select → await load → select row).
+- Wire `TaskMonitorViewModel.OpenInApp` to it (via an `Action<string>?` set by the shell, like the
+  existing `CloseDetail`/`DeleteFromList` hooks — no new DI cycle).
+- Unit test for the select-by-id path. Commit: `feat(ui): reveal a task by id from anywhere`.
+
+### Task 2.3 — `MonitorPaneView` (reuses `SessionTerminalView`)
+- New `Views/MissionControl/MonitorPaneView.axaml(.cs)`: header (title/chip/tok/turn/elapsed),
+  blocking banner (`live-chip`/`terminal`/error-tint classes from IslandStyles — reuse), body =
+  `<SessionTerminalView Entries="{Binding Log}" ... />`, footer (Open in app / Detach / Cancel).
+  `x:DataType=TaskMonitorViewModel`. No new console control. Add `missionControl.*` en+de keys.
+- Build + Localization.Tests. Commit: `feat(ui): add MonitorPaneView`.
+
+### Task 2.4 — `MissionControlView` grid + `MissionControlWindow`
+- `MissionControlView.axaml`: `ItemsControl`/`UniformGrid` of `MonitorPaneView` driven by `ColumnCount`,
+  horizontal scroll fallback, header with `ClearFinished` (+ optional QuickAdd, deferrable).
+- `MissionControlWindow.axaml(.cs)`: hosts the view; lazy-create + hide-on-close.
+- Build. Commit: `feat(ui): add MissionControl window + grid`.
+
+### Task 2.5 — Launch button + lifetime
+- Title-bar toggle button in `MainWindow.axaml` → shell command that shows/focuses the window
+  (created lazily, owns the singleton VM).
+- Set `desktop.ShutdownMode = OnMainWindowClose` in `App.OnFrameworkInitializationCompleted`.
+- Build. **Manual visual pass** (flag for Mika): open with 2+ running tasks; main window still adds
+  tasks; blocking banner; Open-in-app. Commit: `feat(ui): open Mission Control from the title bar`.
+
+---
+
+## Phase 3 — Per-pane detach (lowest priority)
+
+### Task 3.1 — `TaskMonitorWindow` + detach/re-dock
+- `Views/MissionControl/TaskMonitorWindow.axaml(.cs)` hosting `MonitorPaneView`; `Detach` removes the
+  monitor from the grid and shows it in the window (optional always-on-top); close re-docks.
+- Build. Manual visual pass. Commit: `feat(ui): detach a monitor into its own window`.
+
+---
+
+## Cross-cutting checklist (every task)
+- Stage by explicit path; sonnet subagents; reuse per the spec's map — no new console/streaming/insert path.
+- en.json + de.json parity for any new string (Localization.Tests).
+- If `IWorkerClient`/ctor signatures change, update the hand-rolled fakes in **both** test projects.
+- Build `ClaudeDo.App` (`-c Release` if Worker is running) before marking a task done.
+- Never push without asking.

+# Plan — In-App Interactive Sessions
+
+Spec: `docs/superpowers/specs/2026-06-26-in-app-interactive-sessions-design.md`
+
+Implement on the shared main tree. Commit explicit paths per task (never `git add -A`).
+Build with `-c Release` (running Worker locks Debug). No real-Claude tests — fake the
+process stream. Sonnet subagents. Autonomous `TaskRunner`/`ClaudeProcess` path stays untouched.
+
+## Task 1 — StreamingClaudeSession (worker, new file)
+- `Runner/StreamingClaudeSession.cs`: persistent `claude` process. Ctor takes resolved args,
+  working dir, seeded first prompt, a line callback, `WorkerConfig`. Reuse the
+  `ProcessStartInfo` shape + `MCP_TOOL_TIMEOUT="200000"` from `ClaudeProcess`.
+  - Keeps stdin open; sends the first prompt as a user-message JSON line (escape via
+    `JsonSerializer`).
+  - stdout/stderr read tasks → line callback; parse `result` events to track `IsTurnInFlight`.
+  - `SendUserMessageAsync(text, ct)` — enqueue/write a user-message JSON line; if
+    `IsTurnInFlight`, also `InterruptAsync`.
+  - `InterruptAsync(ct)` — write the control-protocol interrupt line; best-effort (swallow +
+    log on failure → queue fallback applies).
+  - `StopAsync` / `DisposeAsync` — close stdin, kill the tree, await exit.
+  - Injectable stream seam so a fake can drive it without a real `claude` binary.
+- Test: `StreamingClaudeSessionTests` (fake stream) — first message emitted; `result` flips
+  `IsTurnInFlight` off; a sent message produces a second turn; mid-turn send calls interrupt
+  then delivers; interrupt throw → delivered at natural turn end; stop kills.
+
+## Task 2 — LiveSessionRegistry (worker, new file)
+- `Runner/LiveSessionRegistry.cs`: singleton; `Register(taskId, StreamingClaudeSession)`,
+  `bool TryGet(taskId, out session)`, `Unregister(taskId)`, `Task StopAsync(taskId)`.
+- Test: register→get; unregister; second register stops+replaces; missing get returns false.
+
+## Task 3 — InteractiveSessionService (worker, new file)
+- `Planning/InteractiveSessionService.cs`: inject `IDbContextFactory`, `WorkerConfig`,
+  `ClaudeArgsBuilder` (or build args inline), `HubBroadcaster`, `LiveSessionRegistry`.
+  - `StartAsync(taskId, ct)`: resolve list working dir + seeded prompt (reuse the body of
+    `PlanningSessionManager.OpenInteractiveAsync` + `BuildInteractivePrompt`); build interactive
+    args (`--model PlanningAlias --permission-mode auto` + streaming flags); spawn the session
+    with a callback that does `HubBroadcaster.TaskMessage(taskId, "[stdout] " + line)`;
+    register; broadcast `InteractiveSessionStarted`. Reject if one is already live for the task.
+  - `SendAsync(taskId, text, ct)` → registry `TryGet` → `SendUserMessageAsync`.
+  - `StopAsync(taskId, ct)` → registry stop + `InteractiveSessionEnded`.
+- Move `OpenInteractiveAsync`/`BuildInteractivePrompt` out of `PlanningSessionManager` if it
+  reads cleaner (or call into it). Remove the `InteractiveLaunchContext` terminal coupling.
+- Test: `InteractiveSessionServiceTests` (fake session factory + fake broadcaster) — start
+  resolves dir, seeds prompt, registers, broadcasts started; missing working dir throws;
+  send routes; stop broadcasts ended.
+
+## Task 4 — Remove terminal interactive path (worker)
+- `Planning/Interfaces/ITerminalLauncher.cs` + `WindowsTerminalLauncher.cs`: delete
+  `LaunchInteractiveAsync`; remove `InteractiveLaunchContext` from `PlanningSessionContext.cs`.
+  Keep planning start/resume launches.
+- Fix any references; ensure the planning launcher tests still build.
+
+## Task 5 — Hub + Broadcaster + DI (worker)
+- `Hub/WorkerHub.cs`: re-point `OpenInteractiveTerminalAsync` to
+  `InteractiveSessionService.StartAsync` (drop `_launcher.LaunchInteractiveAsync`); add
+  `Task SendInteractiveMessage(taskId, text)`, `Task StopInteractiveSession(taskId)`
+  (+ optional `InterruptInteractiveSession`).
+- `Hub/HubBroadcaster.cs`: `InteractiveSessionStarted(taskId)`, `InteractiveSessionEnded(taskId)`.
+- `Program.cs`: register `LiveSessionRegistry` + `InteractiveSessionService` singletons.
+- Test: `WorkerHub` send routes to a fake service; start invokes the service.
+
+## Task 6 — UI client + fakes (ui)
+- `Services/Interfaces/IWorkerClient.cs` + `WorkerClient.cs`: `SendInteractiveMessageAsync(
+  taskId, text)`, `StopInteractiveSessionAsync(taskId)` (+ optional interrupt); events
+  `Action<string>? InteractiveSessionStartedEvent`, `InteractiveSessionEndedEvent` with
+  `On<...>` handlers. `OpenInteractiveTerminalAsync` keeps name/signature.
+- Update hand-rolled `IWorkerClient` fakes in **both** Ui.Tests and Worker.Tests.
+
+## Task 7 — StreamLineFormatter user bubble (ui)
+- Render `type:"user"` NDJSON events as `LogKind.User` (add the kind if missing).
+- Test: a `user` event yields a `LogKind.User` `LogLineViewModel` with the text.
+
+## Task 8 — Shared composer state on the session VMs (ui, hot files)
+- Add to `TaskMonitorViewModel` and `DetailsIslandViewModel` (factor a shared helper —
+  `InteractiveComposer` — to avoid duplication): `ComposerDraft`, `IsInteractiveLive`
+  (toggled by `InteractiveSessionStarted/Ended` for the subscribed task),
+  `SubmitComposerCommand` (CanExecute: non-empty draft && (`HasPendingQuestion` ||
+  `IsInteractiveLive`)). Route: pending question → existing `AnswerTaskQuestionAsync`; else →
+  `SendInteractiveMessageAsync`. Clear draft on submit; clear `IsInteractiveLive` on ended.
+- `MissionControlViewModel`: `EnsureMonitor(taskId)` on `InteractiveSessionStarted`.
+- Test: composer enabled while interactive-live; submit routes (chat vs answer) + clears;
+  ended clears live state.
+
+## Task 9 — SessionTerminalView composer (ui)
+- `Views/Islands/SessionTerminalView.axaml(.cs)`: optional composer docked bottom (styled
+  props `IsComposerVisible`, `ComposerText`, `SubmitCommand`, `ComposerPlaceholder`); TextBox
+  (Enter submits) + Send button. Reuse existing tokens (no inline values).
+- Bind it in `MonitorPaneView.axaml` and `DetailsIslandView.axaml` to each VM's composer
+  state. Fold the existing AskUser banner into the composer's "answering" state if it reads
+  cleaner; otherwise leave the banner and add the composer below.
+
+## Task 10 — Localization
+- `en.json` + `de.json`: `interactive.composer.placeholder`, `.send`, `.stop`, plus any
+  "session ended" notice. Keep parity (Localization.Tests).
+
+## Task 11 — Build + test + verify
+- Build App + Worker `-c Release`; run Worker.Tests, Ui.Tests, Localization.Tests.
+- Self-review diffs. **Manual smoke (real CLI) — flag to Mika:** (a) Run interactively opens
+  an in-app chat (no terminal) and streams; (b) sending a message mid-turn interrupts +
+  redirects; (c) stop kills the process; (d) session shows in both task detail and Mission
+  Control. Do not push.

+# Feature unification — one component per feature
+
+Date: 2026-06-19
+
+## Goal
+
+ClaudeDo grew organically; several features now exist as parallel implementations
+or are reachable through many hand-wired entry points. This design maps the
+duplication and defines a target where **each feature is one component**, reached
+through one path, with dead code removed.
+
+## Method
+
+Mapped via five parallel exploration agents (merge/conflict, review→merge,
+diff+worktree, task create/edit, UI entry-point inventory), then verified the
+load-bearing claims by grep/read before writing this. Every file:line below was
+confirmed against the working tree on 2026-06-19.
+
+## Key finding: it is NOT three merge engines
+
+There is **one** merge engine (`TaskMergeService`), wrapped **once** for multi-child
+units (`PlanningMergeOrchestrator`), with **one** conflict resolver (the Rider
+3-pane). `Worker/CLAUDE.md` already records "there is no separate 'Merge all' entry —
+approve is the single review+merge action." What *looks* like 2–3 merge features is
+**entry-point sprawl** in the UI plus **one dead hunks-API** left over from the
+Layer-C rework. So unification is mostly UI plumbing + deletion, not re-architecting
+the engine.
+
+## Findings — three buckets
+
+### Bucket A — genuine duplication (parallel implementations of one job)
+
+| # | Feature | Duplicated components | Shared already |
+|---|---|---|---|
+| A1 | Diff viewing | `DiffModalViewModel` (worktree + commit-range), `WorktreeModalViewModel` (file-tree + per-file), `PlanningDiffViewModel` (per-subtask + integration) | `UnifiedDiffParser`, `DiffLinesView` (good) |
+| A2 | Agent-config editing | `ListSettingsModalViewModel` (list scope), `AgentSettingsSectionViewModel` (task scope); global lives in `SettingsModalViewModel` | `InheritanceResolver`, `InheritedBadge` (good) |
+| A3 | Worktree actions | `WorktreesOverviewModalViewModel` per-row cmds (Merge/Discard/Keep/ForceRemove/ShowDiff/Jump) vs `MergeSectionViewModel` (Merge/OpenDiff) | same `IWorkerClient` calls |
+| A4 | Merge display | `AgentStripView` re-displays `MergeSectionViewModel` state | — |
+
+### Bucket B — entry-point sprawl (one backend, many hand-wired doors)
+
+| # | Feature | Doors | Evidence |
+|---|---|---|---|
+| B1 | Conflict-resolution seam | 5 copies of `Func<string,string,Task>? RequestConflictResolution` | `WorktreesOverviewModalViewModel.cs:83`, `DiffModalViewModel.cs:75`, `MergeModalViewModel.cs:33`, `MergeSectionViewModel.cs:51`, `DetailsIslandViewModel.cs:347` (delegates). Threaded through `MainWindow.axaml.cs:81`, `IslandsShellViewModel.cs:49/202`, `DiffModalViewModel.cs:103`, `MergeSectionViewModel.cs:159` |
+| B2 | Diff (open) | 3–4 | MergeSection "Open Diff", TaskHeaderBar "Review Merged Diff", WorktreesOverview "Show Diff", Planning "Review Combined" |
+| B3 | List Settings dialog | 3 | Lists context menu, Tasks header button, shell bridge `IslandsShellViewModel.cs:190-194` |
+| B4 | Worktrees Overview | 2–3 | Repos menu (global), Lists context menu (per-list) |
+| B5 | Repo Import | 2 | Repos menu, Lists footer button |
+
+The conflict-resolution *target* is already single-point (`IslandsShellViewModel.RequestConflictResolutionAsync`, line 49). What is duplicated is the **seam plumbing**: five VMs each own the Func and it is threaded by hand.
+
+### Bucket C — dead / leftover
+
+| # | Item | Evidence |
+|---|---|---|
+| C1 | Dead hunks conflict API | `TaskMergeService.GetConflictsAsync` (`Lifecycle/TaskMergeService.cs:250`) ← `WorkerHub.GetMergeConflicts` (`Hub/WorkerHub.cs:378`) ← `WorkerClient` `"GetMergeConflicts"` (`Services/WorkerClient.cs:276`) ← `IWorkerClient`. Live resolver uses `GetMergeConflictDocuments` (`WorkerHub.cs:389`). Only `TaskMergeServiceTests.cs:672` still references the old one. |
+| C2 | Two task-creation paths | UI quick-add `TasksIslandViewModel.AddAsync` writes EF directly (`db.Tasks.Add`); MCP `ExternalMcpService.AddTask` is the service path. They can drift. |
+| C3 | Stale worktrees | `.claude/worktrees/feat+planning-sessions-ui/…` carries old copies of `DiffModalViewModel`/`ListSettingsModalViewModel`/`WorktreeModalViewModel`; layer-c resolver leftovers. Worktree hygiene, not main code. |
+| C4 | Naming drift (deferred) | Hub `StartConflictMerge`/`ContinueConflictMerge`/`AbortConflictMerge` (`WorkerHub.cs:367/405/414`) vs service `MergeAsync`/`ContinueMergeAsync`/`AbortMergeAsync`. **Documented as intentional** at `Worker/CLAUDE.md:153`. |
+
+## Targets — one component per feature
+
+1. **MergeCoordinator (B1).** Replace the five `RequestConflictResolution` Func seams with one injected coordinator exposing `MergeAsync(taskId, targetBranch)` that owns the "merge → on-conflict open resolver" sequence. Every door (review Approve, Diff Merge button, WorktreesOverview single + batch, Details merge section) calls it. The single resolution point (`IslandsShellViewModel.RequestConflictResolutionAsync`) becomes the coordinator's body.
+2. **DiffViewer (A1 + B2).** One `DiffViewerViewModel` + view with a `DiffSource` abstraction (`DirtyWorktree | BranchVsBase | CommitRange | PlanningAggregate | IntegrationBranch`) and an optional file-tree pane. Replaces `DiffModal` + `WorktreeModal` + `PlanningDiff` shells; keeps `UnifiedDiffParser`/`DiffLinesView`. All B2 doors open it with a different source.
+3. **WorktreeActions (A3).** One `WorktreeActionsViewModel` for a single task's worktree (merge/diff/discard/keep/force-remove), reused by both the overview rows and the Details merge section instead of each owning copies.
+4. **AgentConfigEditor (A2).** One editor component parameterized by scope (`Global | List | Task`) over `InheritanceResolver`, embedded in Settings, List Settings, and the Details panel. Collapses the duplicated property set + reset commands + badges.
+5. **DialogService (B3–B5).** Consolidate the per-modal `Show*` Func seams (`IslandsShellViewModel.cs:59-71`) into one `IDialogService` with typed open methods (`OpenListSettings(list)`, `OpenRepoImport()`, `OpenWorktreesOverview(listId?)`…). Menu, context menu, and footer all call the same method; duplicate command definitions across `ListsIsland`/shell collapse to one.
+6. **Single task-creation path (C2).** Route UI quick-add through the same creation path MCP `AddTask` uses (repository/service), so both honor the same invariants.
+
+Plus **C1** (delete dead hunks API + its test) and **C3** (prune stale worktrees) as groundwork. **C4** naming alignment is **deferred** — it is documented-intentional and would churn the hub + `WorkerClient` + every `IWorkerClient` fake (see the "fakes to sync" hazard) for cosmetic gain.
+
+## Decisions
+
+- **Phased, each phase ships green.** Six independently buildable/committable slices; cheapest and lowest-risk first (see the plan). No big-bang.
+- **One plan file per slice.** Matching the 2026-06-05 layer-A/B/C convention, each slice gets its own `docs/superpowers/plans/2026-06-19-unify-<slice>.md` authored when it is picked up. This umbrella plan sequences them and details Phase 0–1.
+- **DiffViewer (A1) is last.** Highest effort and most UX-sensitive (file-tree vs whole-unified are different layouts); deferring it lets the cheaper wins land first and de-risks the big one.
+- **Keep the merge engine and the resolver seam contract.** `TaskMergeService`, `PlanningMergeOrchestrator`, `ConflictResolverViewModel` ctor/`OpenAsync`/`OpenForPlanningAsync`/`CloseRequested` are unchanged — unification is above them.
+- **Naming alignment deferred, not done** (rationale above).
+
+## Out of scope / deferred
+
+- Hub/service merge-method renaming (C4).
+- Subtask deletion in the UI (a missing feature surfaced during mapping, not a duplicate).
+- Any DB migration, worker engine change, or push.
+
+## Acceptance (per phase)
+
+Each phase: `dotnet build -c Release` clean for touched projects; the relevant test
+project green; locales in parity (Localization.Tests) where keys change; the feature
+reachable through its single new path with the old doors removed or delegating. UI
+phases (2–5) flag a visual-verification gap for Mika to confirm in the running app.

+# Worker log → footer auto-route + Log Visualizer overlay
+
+**Date:** 2026-06-23
+**Status:** approved (design forks resolved with user)
+
+## Goal
+
+1. Auto-route **all Worker WARN/ERROR** Serilog events to the footer status strip (today only ~10 hand-curated business events reach it).
+2. Make the footer log line **clickable** → opens a **Log Visualizer overlay** showing the **last 30 min** of logs at **all levels**, color-coded.
+3. **Dedupe/rate-limit** the footer so repeating warnings (e.g. the current 60s OIDC-discovery failure) don't strobe.
+
+## Decisions (locked)
+
+- **Overlay source:** Worker-side **in-memory ring buffer** (30-min window, all levels), fetched via a hub call. No log-file parsing.
+- **Levels:** overlay shows INF/WRN/ERR; footer flashes **WARN/ERROR only**.
+- **Footer noise:** per-message dedupe within a rate-limit window (suppress the footer broadcast for an identical message seen recently; the event is still buffered for the overlay).
+
+## Architecture
+
+### Worker
+
+- **`LogRingBuffer`** (singleton, `Logging/`): thread-safe, time-bounded (`TimeSpan` window, default 30 min) + hard cap (e.g. 5000) ring of `WorkerLogRecord(Message, Level, TimestampUtc)`. Evicts on append by age + cap. `Snapshot()` returns newest-last.
+- **`BroadcastLogSink : Serilog.Core.ILogEventSink`** (`Logging/`): for every `LogEvent` —
+  - map level: Verbose/Debug/Information→`Info`, Warning→`Warn`, Error/Fatal→`Error`;
+  - render `msg = evt.RenderMessage()` (+ `": {ex.GetType().Name}: {ex.Message}"` first-line if `evt.Exception != null`);
+  - append to `LogRingBuffer` (all levels);
+  - if `Warn|Error` **and** not rate-limited: fire-and-forget `HubBroadcaster.WorkerLog(msg, level, evt.Timestamp.UtcDateTime)`.
+  - **Loop guard:** wrap the broadcast in try/catch and swallow; skip broadcasting events whose `SourceContext` is SignalR/connections plumbing (still buffered). Broadcasting must never itself log.
+  - **Dedupe/rate-limit:** dict `message → lastBroadcastUtc`; suppress footer broadcast if `now - last < RateLimitWindow` (const, 120 s). Periodic prune of the dict.
+- **DI wiring (chicken-egg):** `LogRingBuffer` + `BroadcastLogSink` are created as locals in `Program.cs` *before* `builder.Build()`, captured into `UseSerilog(... .WriteTo.Sink(broadcastSink))`, and registered as singletons. `HubBroadcaster` doesn't exist until post-build, so the sink starts detached; after `builder.Build()` we call `broadcastSink.Attach(app.Services.GetRequiredService<HubBroadcaster>())`. Buffering works from process start; broadcasting begins once attached.
+- **Hub:** `WorkerHub.GetRecentLogs() -> IReadOnlyList<WorkerLogRecordDto>` reads `LogRingBuffer.Snapshot()`. (Read-only, no auth beyond existing hub.)
+
+### UI
+
+- **IWorkerClient / WorkerClient:** add `Task<IReadOnlyList<WorkerLogEntry>> GetRecentLogsAsync(CancellationToken ct = default)`. ⚠ Update hand-rolled fakes in **both** test projects (StubWorkerClient + Worker.Tests UiVm fake).
+- **Footer:** wrap the worker-log `TextBlock` so it's clickable (Button, transparent) → `IslandsShellViewModel.OpenLogVisualizerCommand`. Existing `OnWorkerLogReceived` already routes the (now more numerous) `WorkerLog` broadcasts to the strip — **no change needed** for footer routing itself.
+- **`LogVisualizerViewModel`** (Modals/): on open, `GetRecentLogsAsync()` → `ObservableCollection<LogLineViewModel>` (msg, level→brush, HH:mm:ss). A level filter (All / Warn+Err) and a Refresh command. MVP = snapshot on open + Refresh; live-tail is a later nicety.
+- **`LogVisualizerView`** (Modals/): `ModalShell`-based dialog (consistent with other modals), shown via `IDialogService.ShowLogVisualizerAsync(vm)`. Small, scrollable, monospaced, color-coded lines.
+- **Localization:** new `vm.logVisualizer` (+ any view keys) in **en.json + de.json** (parity test enforces).
+
+## Out of scope / follow-ups
+
+- Live-tail while the overlay is open (snapshot + Refresh for MVP).
+- The **OIDC-discovery-every-60s failure** is a *separate* bug (Online Inbox enabled, `auth.kuns.dev` SSL fails). Dedupe tames the footer symptom; the root cause is tracked separately.
+
+## Tests
+
+- Worker: `LogRingBufferTests` (age + cap eviction, snapshot order), `BroadcastLogSinkTests` (level mapping; all levels buffered; only Warn/Err broadcast; dedupe suppresses repeat broadcast within window but still buffers; exception rendering; loop-guard source filter).
+- UI: `LogVisualizerViewModelTests` (loads from worker, populates, filter). Footer-click wiring smoke.

+# Interactive "Answer Claude's Questions" — Design
+
+**Date:** 2026-06-25
+**Status:** Approved (brainstormed with Mika)
+
+## Goal
+
+Let the user answer a question Claude raises *mid-run* from inside Mission Control,
+without leaving the autonomous-execution model. Not a chat panel, not a terminal, not
+proactive steering — only: *Claude surfaces a question → the user types an answer → the
+run continues with that answer in context.*
+
+User decisions (brainstorm):
+- Scope: "I mostly want to answer his questions if he surfaces any."
+- Trigger: **any running task** may ask, with a **3-minute** answer window.
+
+## Why not the alternatives
+
+- **Embedded terminal / PTY** — would destroy the NDJSON contract the whole worker
+  pipeline depends on (StreamAnalyzer, token accounting, auto-commit, status flow) and
+  needs a terminal-emulator control Avalonia doesn't have. Rejected.
+- **Streaming-stdin (`--input-format stream-json`)** — right tool for a free-form chat,
+  overkill here. Rejected for v1.
+- **`--resume` per-turn** — already exists; not live (cold process per turn).
+
+## Mechanism
+
+The in-task MCP already blocks the `claude -p` process while a tool call is in flight.
+That blocking *is* the pause. Add one in-task MCP tool, `AskUser(question)`:
+
+1. The tool resolves the caller task id, registers a pending question + a
+   `TaskCompletionSource<string>` in a singleton `PendingQuestionRegistry`, and
+   broadcasts `TaskQuestionAsked(taskId, questionId, question)`.
+2. Mission Control surfaces the question with an input box.
+3. The user answers → `WorkerHub.AnswerTaskQuestion` resolves the TCS → the tool
+   returns the answer as its result → Claude continues.
+4. No answer within **3 minutes** → the tool returns *"No response received within 3
+   minutes — proceed using your best judgment."* and the run carries on autonomously.
+
+### Key facts that make this work
+
+- **No persisted status change.** The task is still genuinely `Running` (process alive,
+  blocked mid-tool-call). "Waiting for input" is **ephemeral**: in-memory registry +
+  live SignalR events + a UI overlay. No `TaskStatus` enum value, no `TaskStateService`
+  transition, **no EF migration**. If the worker dies mid-wait, `StaleTaskRecovery`
+  flips the orphaned `Running` row to `Failed` like any interrupted run.
+- **`MCP_TOOL_TIMEOUT` must be raised.** Claude Code caps HTTP MCP tool calls at **60 s**
+  by default. The `claudedo_run` MCP is HTTP, so `ClaudeProcess` must set
+  `MCP_TOOL_TIMEOUT=200000` (≈3 min + margin) on the spawned process or the 3-min window
+  is silently truncated to 60 s.
+- **MCP wired for all runs.** Today `TaskRunner` only mints the run MCP for standalone
+  top-level tasks (for `SuggestImprovement`). To satisfy "any running task," move the
+  MCP-identity setup out of that gate so every `RunAsync` gets `claudedo_run`.
+  `AllowedTools` always includes `mcp__claudedo_run__AskUser`; `SuggestImprovement` stays
+  gated to improvement-eligible (standalone) runs.
+
+## Surface changes
+
+**Worker (mostly new files):**
+- `Runner/PendingQuestionRegistry.cs` (new, singleton) — `Register`, `TryAnswer`, `Get`,
+  `Remove`; one pending question per task.
+- `Runner/TaskRunMcpService.cs` (edit) — add `AskUser` `[McpServerTool]`; inject the
+  registry.
+- `Runner/TaskRunner.cs` (edit) — wire MCP identity for all runs; add `AskUser` to
+  allowed tools.
+- `Runner/ClaudeProcess.cs` (edit) — set `MCP_TOOL_TIMEOUT` env.
+- `Hub/HubBroadcaster.cs` (edit) — `TaskQuestionAsked`, `TaskQuestionResolved`.
+- `Hub/WorkerHub.cs` (edit) — `AnswerTaskQuestion`, `GetPendingQuestion` + DTO.
+- `Program.cs` (edit) — register `PendingQuestionRegistry` singleton.
+- System prompt (edit) — one line telling Claude the tool exists and to use it only when
+  a wrong guess would be costly/irreversible (otherwise proceed).
+
+**UI:**
+- `Services/IWorkerClient.cs` + `WorkerClient.cs` (edit) — `AnswerTaskQuestionAsync`,
+  `GetPendingQuestionAsync`, `TaskQuestionAskedEvent`, `TaskQuestionResolvedEvent`.
+- `ViewModels/Islands/TaskMonitorViewModel.cs` (edit, **hot file**) — pending-question
+  state, `AnswerDraft`, `SubmitAnswerCommand`, clear on finish/resolve.
+- `ViewModels/MissionControlViewModel.cs` (edit) — hydrate pending question on attach.
+- `Views/MissionControl/MonitorPaneView.axaml` (edit, **hot file**) — additive
+  question/answer banner above the terminal.
+- `Localization/locales/en.json` + `de.json` — `missionControl.question.*` keys.
+
+**Tests:** `PendingQuestionRegistry` (answer/timeout/unknown/overwrite), `AskUser` tool
+(answer + timeout fallback, fake broadcaster — no real Claude), `TaskMonitorViewModel`
+(surface/submit/clear). Update IWorkerClient fakes in both test projects.
+
+## Concurrency note
+
+Two files (`TaskMonitorViewModel.cs`, `MonitorPaneView.axaml`) are also being touched by
+a concurrent Mission Control drag-and-drop session on the shared main tree. Keep edits
+additive, commit explicit paths only (never `git add -A`).
+
+## Verification gaps (manual)
+
+1. **Real-Claude smoke test** — confirm a blocking `AskUser` call survives ≥3 min with
+   `MCP_TOOL_TIMEOUT=200000` and that the model actually calls the tool when uncertain.
+2. **Visual** — the question banner + input box in the pane (Mika does the visual pass).
+
+## Non-goals
+
+Free-form chat panel; proactive steering; tool-permission prompts (stays `auto`);
+`ContinueAsync`/resumed runs gaining `AskUser` (deferred follow-up).

+# Mission Control — multi-task live monitoring
+
+Date: 2026-06-25
+Status: approved (design); implementation not started
+
+## Problem
+
+The UI can observe only **one** running task at a time. `DetailsIslandViewModel` is hard 1:1
+(single `Task`, single `_subscribedTaskId`); selecting another task in the middle pane *replaces*
+what Details shows. Yet the worker runs several tasks concurrently (`MaxParallelExecutions`) and
+already broadcasts every task's live output to all clients keyed by `taskId`. So the user cannot
+watch multiple in-flight sessions, and monitoring blocks normal work (adding tasks, reviewing).
+
+## Goal
+
+Watch several running tasks at once **without** giving up the normal app. Requirements drawn from
+the brainstorm:
+
+- A **live console grid** — multiple full Claude output streams side by side.
+- Each pane also shows **task details, blocking reasons**, and a **navigation helper** to open the
+  monitored task in the main app.
+- Lives in a **separate, always-available window** so the main window stays fully usable (adding
+  tasks must never be blocked). Combines "full window" + "detachable".
+
+## Non-goals
+
+- No worker/SignalR changes. The broadcast layer is already N-capable (`TaskMessage(taskId,line)`,
+  `TaskStarted/Finished/Updated`, `GetActive()`). This is a UI/VM-only feature.
+- No second SignalR connection. The new window shares the existing singleton `IWorkerClient`.
+- No new merge/review engine. Review/merge stays in the main window's Details pane; Mission Control
+  is read-mostly (monitor + cancel + navigate).
+
+## Hard constraint: no duplicated components or features
+
+This feature is an **extract-and-reuse** exercise, not a rebuild. The single biggest risk is
+forking a second live-streaming/parsing/status implementation. The reuse map below is binding.
+
+### Reuse map (what already exists — use it, do not copy it)
+
+| Concern | Existing asset | Location | How Mission Control uses it |
+|---|---|---|---|
+| Live console body (log list, LIVE/DONE/FAILED chip, auto-scroll) | `SessionTerminalView` (StyledProps `Entries`, `Label`, `IsRunning/IsDone/IsFailed`) | `Views/Islands/SessionTerminalView.axaml(.cs)` | Bind a pane's `Entries`→its `Log`, status flags + label. **No new console control.** |
+| Log line model | `LogLineViewModel` + `LogKind` | `ViewModels/Islands/DetailsIslandViewModel.cs` (top) | Shared model — move to its own file so both consumers reference one type. |
+| Live stream parse/replay | `OnTaskMessage` / `AppendStdoutLine` / `FlushClaudeBuffer` / `ReplayLogFileAsync` + `StreamLineFormatter` + `ExpandUserPath` | private in `DetailsIslandViewModel.cs` | **Extract to `TaskMonitorViewModel`** (Phase 1). One streaming engine, two consumers. |
+| Status state machine | `AgentState` + `Is*` flags + `StatusToStateKey` / `FinishedStatusToStateKey` | `DetailsIslandViewModel.cs` | Extract into `TaskMonitorViewModel`. |
+| Outcome / roadblock split | `ApplyOutcome` + `RoadblockMarker` constant | `DetailsIslandViewModel.cs` | Extract into `TaskMonitorViewModel`. |
+| Status chip / terminal styling | `live-chip`, `terminal`, `log-*` style classes | `Design/IslandStyles.axaml` | Reuse the classes as-is. |
+| Add a new task | `TasksIslandViewModel.AddAsync` (`NewTaskTitle`, user-list only, direct `TaskRepository`) | `TasksIslandViewModel.cs:406` | Optional quick-add reuses this path; **must not** introduce a second insert path. |
+| Live task list | `IWorkerClient.GetActive()` + `TaskStarted/Finished` events | worker hub / `WorkerClient` | Populate the grid; add/remove panes. |
+| DI / singletons | `IslandsShellViewModel`, `DetailsIslandViewModel`, `IWorkerClient` all singletons | `App/Program.cs` | Register `MissionControlViewModel` singleton; inject existing singletons. |
+
+## Design
+
+### TaskMonitorViewModel (the reusable core — new, but carved out of DetailsIslandViewModel)
+
+One instance == one monitored task. Owns:
+
+- `Log` (`ObservableCollection<LogLineViewModel>`), the filtered `TaskMessageEvent` subscription
+  (by `taskId`), stdout buffering, and NDJSON replay from disk on attach.
+- `AgentState` + `Is*` flags; `SessionOutcome` / `Roadblocks` (the outcome split).
+- Lightweight display: `Title`, `TaskIdBadge`, `Model`, `TurnsText`, `TokensFormatted`,
+  diff add/del, elapsed.
+- `BlockingReason` (string/visible flag) derived from existing data: `BlockedByTaskId`
+  (planning/child chain), `WaitingForReview` / `WaitingForChildren` status, and roadblock markers.
+- Commands: `OpenInApp`, `Detach`, `Cancel`.
+- `IDisposable` — unsubscribes all worker events (mirror DetailsIslandViewModel.Dispose).
+
+`DetailsIslandViewModel` is refactored to **own one `TaskMonitorViewModel` (`public Monitor`)** and
+delegate streaming/status/outcome to it. Its heavy concerns (subtasks, attachments, editing, merge
+cockpit, review verbs, child outcomes, notes/prep modes) stay put. **Phase 1 must be a no-behavior-
+change refactor** — all existing Ui.Tests stay green.
+
+> Binding-surface decision (Phase 1): repoint `WorkConsole.axaml`'s Output-tab bindings that
+> reference streaming/status (`Log`, `IsRunning/IsDone/IsFailed`, `SessionOutcome`, `TurnsText`,
+> diff text, `Model`) to `Monitor.*`. `x:DataType` stays `DetailsIslandViewModel`; compiled bindings
+> handle the nested path. Review/merge/session bindings are untouched. Prefer repointing over adding
+> ~15 forwarding properties (one source of truth, no boilerplate).
+
+### MissionControlViewModel (new)
+
+- `ObservableCollection<TaskMonitorViewModel> Monitors`, keyed by `taskId`.
+- On open: seed from `GetActive()`. On `TaskStarted`: add a monitor. On `TaskFinished`: keep the
+  pane (so the final output stays readable) but flip its state; a "clear finished" action prunes them.
+- Adaptive layout signal (column count) from `Monitors.Count`:
+  `1→1col, 2→2col, 3–4→2col(2 rows), 5+→fixed-width panes, horizontal scroll`. Least-active panes
+  beyond a threshold collapse to a compact card (title + last line + chip), click to expand — this is
+  the readability fallback so we never render N unreadable slivers.
+- Optional `QuickAdd` (deferred within Phase 2): title + target user-list → the **same** creation
+  path as `TasksIslandViewModel.AddAsync` (shared method, not a copy).
+- Disposes every monitor on window close.
+
+### Windowing (new plumbing — thin)
+
+- `MissionControlWindow` (Avalonia `Window`) hosting `MissionControlView`; DataContext =
+  the singleton `MissionControlViewModel`.
+- No non-modal secondary-window precedent exists (all current dialogs use `ShowDialog(owner)`), so
+  this is genuinely new but small:
+  - Set `desktop.ShutdownMode = OnMainWindowClose` in `App.OnFrameworkInitializationCompleted` so
+    closing Mission Control never quits the app, and closing the main window does.
+  - Open via a **title-bar button in MainWindow** (toggle: show / focus-if-open). The window is
+    created lazily and hidden (not destroyed) on close so its monitors persist cheaply.
+  - Persist size/position (reuse the ui.config.json mechanism if present; otherwise defer).
+
+### MonitorPaneView (new view, reuses SessionTerminalView)
+
+```
+┌─ #142  Refactor auth module ───────── ● running ─┐   header: title, live chip, tok/turn/elapsed
+│  ⏱ 4m12s   ◆ 18.3k tok   ↻ turn 6                 │

+│  [↗ Open in app]   [⧉ Detach]   [✕ Cancel]        │   footer
+└───────────────────────────────────────────────────┘
+```
+
+### Navigation helper "Open in app" (new shell method)
+
+No select-by-id exists today. Add `IslandsShellViewModel.RevealTaskAsync(taskId)`:
+1. resolve the task's list, set `Lists.SelectedList`; 2. await `Tasks.LoadForList`; 3. find the row in
+`Tasks.Items` by id, set `Tasks.SelectedTask` (→ `Details.Bind`); 4. bring MainWindow to front.
+`TaskMonitorViewModel.OpenInApp` calls this. Single navigation entry point — no duplicate selection logic.
+
+### Detach (Phase 3)
+
+`Detach` moves a `TaskMonitorViewModel` out of the grid into a small `TaskMonitorWindow`
+(reuses `MonitorPaneView`), optionally always-on-top; closing it re-docks. Lowest priority.
+
+## Risks / open items
+
+- **Phase 1 binding repoint** is the main risk: a missed `WorkConsole` binding shows as a blank
+  field, not a build error. Mitigation: Ui.Tests + a manual visual pass on the Details pane.
+- **Localization parity** (Localization.Tests): every new visible string needs en + de keys under a
+  `missionControl.*` namespace.
+- **Quick-add coupling** across windows is the weakest part; kept optional/deferrable.
+- Detached windows = most plumbing, least daily payoff → Phase 3, last.
+
+## Verification
+
+- Build `ClaudeDo.App` + run Ui.Tests / Localization.Tests after each phase.
+- Manual visual pass (cannot be auto-verified): Details pane unchanged after Phase 1; grid populates
+  with 2+ concurrent tasks, blocking banner shows, Open-in-app surfaces the task, adding a task in the
+  main window works while Mission Control is open.

+# In-App Interactive Sessions — Design
+
+**Date:** 2026-06-26
+**Status:** Proposed (awaiting approval)
+
+## Goal
+
+Replace the external Windows-Terminal "Run interactively" session with an **in-app
+streaming chat**, rendered in the existing `SessionTerminalView` in **both task detail and
+Mission Control**. Keep everything inside the app — no `wt.exe` pop-out. Autonomous task
+execution is **untouched** (stays one-shot, non-interactive).
+
+## Decisions (brainstorm)
+
+1. **Engine: persistent streaming session.** One `claude` process kept alive with
+   `--input-format stream-json`; user messages pushed over stdin.
+2. **Scope: interactive sessions only.** The autonomous `TaskRunner`/`ClaudeProcess` run
+   loop, review, queue, and worktree machinery are NOT changed.
+3. **Placement: shared `SessionTerminalView`** — the in-app session + composer appear in the
+   task-detail session surface and in the Mission Control monitor pane.
+4. **Full replace.** "Run interactively" now opens the in-app session; the
+   `WindowsTerminalLauncher.LaunchInteractiveAsync` path is removed. **Planning** sessions
+   keep using `wt` (untouched).
+5. **Send semantics: interrupt + redirect** mid-turn (control protocol), with automatic
+   *queue-for-next-turn* fallback if interrupt is unavailable.
+
+## What an interactive session is (unchanged semantics, new transport)
+
+Today (`PlanningSessionManager.OpenInteractiveAsync` + `WindowsTerminalLauncher`):
+`claude --model <PlanningAlias> --permission-mode auto "<task title+description>"` in the
+**list's working dir**, env `MAX_THINKING_TOKENS=20000`, full default toolset, relies on the
+globally-registered `claudedo` MCP. **Ephemeral** — no worktree, no `task_run` record, no
+status change, no review.
+
+We keep all of that. Only the transport changes: instead of a `wt` window, the same
+`claude` invocation runs as a persistent stream-json process owned by the worker, its output
+streamed into the app and its stdin fed from an in-app composer.
+
+> Honest tradeoff: the `wt` terminal gave the full Claude Code TUI (slash-command UX,
+> interactive prompts). An in-app stream-json chat is plainer — type messages, watch streamed
+> output. `--permission-mode auto` means no blocking permission prompts (so headless works),
+> but it is a simpler surface than the real TUI. Accepted per the "full replace" decision.
+
+## The streaming engine
+
+Flags: `--model <PlanningAlias> --permission-mode auto --input-format stream-json
+--output-format stream-json --verbose --replay-user-messages` in the list working dir, env
+`MAX_THINKING_TOKENS=20000`. No `--mcp-config`/`--allowedTools` (interactive uses the global
+MCP + default tools, exactly as today).
+
+- First stdin message = the seeded interactive prompt:
+  `{"type":"user","message":{"role":"user","content":[{"type":"text","text":"…"}]},"parent_tool_use_id":null}\n`
+  (stdin stays open).
+- A stdout read task forwards each NDJSON line to a callback (→ broadcast + the session's log)
+  and detects `result` events (turn boundary; the process then idles for the next message).
+- `SendUserMessageAsync(text)` writes a user-message JSON line; if a turn is in flight, also
+  `InterruptAsync()` (control-protocol interrupt) so Claude pivots immediately. If interrupt
+  is unavailable, the message lands when the current turn ends → automatic queue fallback.
+- **Interrupt is verified working** (spike, 2026-06-26, CLI 2.1.191). Exact shape:
+  `{"type":"control_request","request_id":"<id>","request":{"subtype":"interrupt"}}` — no
+  `initialize` handshake needed; `control_response {"subtype":"success"}` confirms
+  synchronously; the same process then accepts the redirect and runs a fresh turn with
+  context intact.
+- **Interrupt artifact:** the aborted turn emits a `result` with `is_error=true,
+  subtype="error_during_execution"`. The session must treat an interrupt-induced result as
+  *"turn aborted, continue"* (drain the queued redirect), **not** as a session failure.
+  Tolerate the incidental `system:init`/`system:status`/`rate_limit_event`/hook events that
+  also appear in the stream.
+- `--replay-user-messages` echoes each sent message back on stdout as a `user` event, so it
+  rides the existing stream pipeline into the timeline (ordered + confirmed) with no extra
+  broadcast surface.
+- The session ends only when the **user stops it** (kill the process tree) — an interactive
+  session has no auto-finalize and never enters review. No queue slot is involved (it is
+  launched directly, not via the autonomous picker).
+
+## Surface changes
+
+**Worker**
+- `Runner/StreamingClaudeSession.cs` (new) — persistent process + send/interrupt/stop; reuse
+  the `ProcessStartInfo` shape + `MCP_TOOL_TIMEOUT` from `ClaudeProcess`; streams via a line
+  callback; `IsTurnInFlight`. Cancellation kills the tree.
+- `Runner/LiveSessionRegistry.cs` (new, singleton) — `taskId → StreamingClaudeSession`
+  (`Register`/`TryGet`/`Unregister`/`Stop`), mirrors `PendingQuestionRegistry`.
+- `Planning/InteractiveSessionService.cs` (new) — owns interactive lifecycle: `StartAsync(
+  taskId)` resolves the list working dir + seeded prompt (reuse `OpenInteractiveAsync`'s
+  body), spawns the session, registers it, wires output to `HubBroadcaster.TaskMessage`,
+  broadcasts `InteractiveSessionStarted`; `SendAsync(taskId, text)`; `StopAsync(taskId)` →
+  `InteractiveSessionEnded`.
+- `Planning/WindowsTerminalLauncher.cs` + `Planning/Interfaces/ITerminalLauncher.cs` — remove
+  `LaunchInteractiveAsync` (+ `InteractiveLaunchContext`). Planning start/resume stay.
+- `Hub/WorkerHub.cs` — `OpenInteractiveTerminalAsync` re-pointed to
+  `InteractiveSessionService.StartAsync` (no terminal); add `SendInteractiveMessage(taskId,
+  text)`, `StopInteractiveSession(taskId)` (+ optional `InterruptInteractiveSession`).
+- `Hub/HubBroadcaster.cs` — `InteractiveSessionStarted(taskId)`,
+  `InteractiveSessionEnded(taskId)`. Log lines reuse the existing `TaskMessage(taskId, line)`.
+- `Program.cs` — register `LiveSessionRegistry` + `InteractiveSessionService`.
+
+**UI**
+- `Views/Islands/SessionTerminalView.axaml(.cs)` — add an optional composer (styled
+  properties: `IsComposerVisible`, `ComposerText`, `SubmitCommand`, `ComposerPlaceholder`).
+  Both hosts (task detail + Mission Control) get it by binding their VM's composer state.
+- `StreamLineFormatter` — render `type:"user"` NDJSON events as a `LogKind.User` bubble.
+- A small shared composer concept on `TaskMonitorViewModel` **and** `DetailsIslandViewModel`
+  (factor a helper to avoid duplication): `ComposerDraft`, `SubmitComposerCommand`,
+  `IsInteractiveLive` (set by `InteractiveSessionStarted/Ended`). Submit →
+  `SendInteractiveMessageAsync`; clear draft. (If a pending AskUser question exists, the same
+  composer answers it — keep the existing answer route.)
+- `MissionControlViewModel` — `EnsureMonitor(taskId)` on `InteractiveSessionStarted` so the
+  session appears as a monitor; mark it interactive.
+- `Services/Interfaces/IWorkerClient.cs` + `WorkerClient.cs` — `SendInteractiveMessageAsync`,
+  `StopInteractiveSessionAsync` (+ optional interrupt); events
+  `InteractiveSessionStartedEvent`/`InteractiveSessionEndedEvent`. `OpenInteractiveTerminalAsync`
+  keeps its name/signature (now starts the in-app session). Update hand-rolled fakes in **both**
+  test projects (`iworkerclient_fakes_sync`).
+- `TasksIslandViewModel.RunInteractivelyAsync` — unchanged call site; now opens/focuses the
+  in-app session surface instead of a terminal.
+- Localization `interactive.*` / `missionControl.chat.*` (en/de, parity enforced).
+
+**Tests**
+- `StreamingClaudeSessionTests` (fake process stream, no real Claude): first message streams;
+  `result` idles; a sent message starts another turn; mid-turn send calls `InterruptAsync`
+  then delivers; interrupt-failure degrades to queue; stop kills.
+- `LiveSessionRegistryTests` — register/get/unregister/stop.
+- `InteractiveSessionServiceTests` — start resolves working dir + seeds prompt + registers +
+  broadcasts started; send routes to the session; stop broadcasts ended (fake session +
+  broadcaster).
+- `TaskMonitorViewModelTests` / `DetailsIslandViewModelTests` — composer enabled while
+  interactive-live; submit invokes client + clears; `user` line renders; question route still
+  answers.
+
+## Risks / open questions
+
+- **Interrupt protocol shape — RESOLVED** (spike 2026-06-26, see "The streaming engine").
+  Mid-turn interrupt works on CLI 2.1.191 with the documented shape; the queue fallback is a
+  genuine fallback now, not the expected path. Re-verify if the CLI version changes.
+- **Plainer than the TUI** — slash-command/interactive-prompt UX differs (accepted).
+- **Auto-mode editing the list working dir directly** (no worktree) — this is the *existing*
+  interactive behavior, unchanged here.
+- **No real-Claude tests** (project rule) — the live loop is covered only by the fake stream;
+  real interrupt/redirect is a **manual verification gap** to flag.
+
+## Non-goals
+
+- Changing autonomous task execution / review / queue / worktrees.
+- Interactive sessions producing run records, worktrees, or review (stays ephemeral).
+- Worktree isolation for interactive edits; image/attachment messages in the composer.
+- Removing planning's `wt` terminal launch.

Migration `DailyPrepMaxTasks` added the `daily_prep_max_tasks` column to `app_settings` (no new tables).

 ## ViewModels
 
-- **IslandsShellViewModel** — root coordinator; owns the three island VMs and the `WorkerClient`, wires cross-island events (selection, notes/prep mode, conflict resolution), owns connection state, the update banner, the inline worker-log strip, responsive-layout flags (`ShowLists`/`ShowDetails` by window width), `PrimeStatus` flash, and the modal openers (About, RepoImport, WeeklyReport, WorktreesOverview, WorkerConnection help) plus `RestartWorkerAsync`/`CheckForUpdatesAsync`. Hosts `UpdateCheckService`.
+- **IslandsShellViewModel** — root coordinator; owns the three island VMs and the `WorkerClient`, wires cross-island events (selection, notes/prep mode, conflict resolution), owns connection state, the update banner, the inline worker-log strip (clickable → Log Visualizer overlay via `OpenLogVisualizerCommand`; `FlashFooterError` surfaces UI-action failures + the worker's Serilog Warn/Error there), responsive-layout flags (`ShowLists`/`ShowDetails` by window width), `PrimeStatus` flash, and the modal openers (About, RepoImport, WeeklyReport, WorktreesOverview, WorkerConnection help, LogVisualizer) plus `RestartWorkerAsync`/`CheckForUpdatesAsync`. Hosts `UpdateCheckService`.
 - **ListsIslandViewModel** — smart lists (My Day, Important, Planned, virtual queued/running/review), user lists, selection, list CRUD, drag-reorder, badge counts, opens list settings / repo import / worktrees overview, `OpenInExplorer`/`OpenInTerminal`.
 - **TasksIslandViewModel** — open/overdue/completed groups for the selected list with hierarchy-aware regrouping; task CRUD, drag-reorder, toggle done/star, schedule, enqueue/dequeue, cancel; review actions (approve, reject-rerun, reject-park, cancel); planning session lifecycle (open/resume/discard/finalize, `QueuePlanningSubtasksAsync`); `RunInteractivelyAsync`, `RefineTask`; MyDay extras (`IsMyDayList`, `ClearDayCommand`, `ShowPrepLogCommand`) and the pinned Notes pseudo-row (`ShowNotesRow`, `OpenNotesCommand`). Raises `NotesRequested`/`PrepRequested` events consumed by the shell.
-- **DetailsIslandViewModel** — the detail pane for a bound `TaskRowViewModel`. Owns live-log streaming (`Log` via `StreamLineFormatter`), debounced title/description editing, subtasks, session-outcome/roadblock split (splits `Result` at the roadblock marker into two cards), the three-tab work console (`output`/`git`/`session`), child surfacing (`ChildOutcomes` rows plus `ChildrenNeedingAttention`/`HasChildrenNeedingAttention` — children that failed, were cancelled, await review, or reported roadblocks — drive an attention band on the Session tab, which is only visible when `HasChildOutcomes`), and the modes: `IsNotesMode` (hosts `NotesEditorViewModel`), `IsPrepMode`, computed `IsTaskDetailVisible = !IsNotesMode && !IsPrepMode`. Three concerns are extracted into section VMs exposed as properties: **AgentSettingsSectionViewModel** (per-task Model/MaxTurns/AgentPath overrides with `InheritedBadge` + `InheritanceResolver`, additive SystemPrompt, debounced save), **MergeSectionViewModel** (merge-target selection, mergeability indicator via `MergePreviewPresenter` over `PreviewMergeAsync`, `OpenDiffAsync` — live worktree or commit range after merge —, `ReviewCombinedDiffCommand` → `PlanningDiffViewModel`), **PrepPanelViewModel** (daily-prep panel: `PrepLog`, `PlanDayCommand` → `RunDailyPrepNowAsync`, persisted last run via `GetLastPrepLogAsync`). Helper rows (`ChildOutcomeRowViewModel`, `SubtaskRowViewModel`, `LogLineViewModel`) live in the same file.

Attachments: `Attachments` (`ObservableCollection<AttachmentRowViewModel>`), `IsDragOver`, `DropStatus`, `CanAcceptDrop`, `AddFilesAsync`, `RemoveAttachmentCommand`; loads on task change; `ComposedPreview` includes attachment paths. Writes directly via `new AttachmentStore()` + `new TaskAttachmentRepository(ctx)`. Helper rows (`ChildOutcomeRowViewModel`, `SubtaskRowViewModel`, `LogLineViewModel`, `AttachmentRowViewModel`) live in the same file.
 - **TaskRowViewModel** / **ListNavItemViewModel** — lightweight display VMs (task row: status, planning phase, parent/blocked links, roadblock count, computed `IsDraft`/`IsPlanned`/`IsChild`/`IsPlanningParent`/`CanRefine`; list row: kind Smart/Virtual/User, count, icon/dot keys, drop hints).
 - **NotesEditorViewModel** — day navigator + bullet CRUD for daily notes via `INotesApi`.
-- **Modal VMs** — `SettingsModalViewModel` (four tabs: General, Worktrees, Files prompt-paths, Prime Claude incl. `DailyPrepMaxTasks` + prime-schedule rows), `ListSettingsModalViewModel` (name, working dir, commit type, per-list Model/SystemPrompt/AgentPath/MaxTurns with inherited-badge + reset, delete list), `RepoImportModalViewModel` (bulk-create lists from git repos found under chosen parents; already-wired repos disabled), `WeeklyReportModalViewModel` (range pickers default "since last standup weekday → today", cached per range, markdown via MarkdownView), `MergeModalViewModel` (single-task merge form, called from the diff modal), `WorktreesOverviewModalViewModel` (global/per-list worktree rows, batch merge + state ops), `UnfinishedPlanningModalViewModel` (Resume/FinalizeNow/Discard for a draft planning session), `WorkerConnectionModalViewModel` (offline help), `AboutModalViewModel`.
-- **Diff stack** — `UnifiedDiffParser` (static; parses `git diff` output into `DiffFileViewModel`s, detecting added/deleted/renamed/binary files and per-line numbers; `Flatten` injects file-header rows for a combined single-pane view). `DiffModalViewModel` has two modes: live worktree (branch diff vs base, with a Merge action) and commit-range `base..head` (`FromCommitRange = true` — shows a merged task's diff after its worktree is gone; no merge action). The view renders a file list with binary/empty placeholders via `DiffLinesView`.
-- **Planning/Conflicts** — `PlanningDiffViewModel` (per-subtask diffs via `GetPlanningAggregateAsync`, toggle to combined integration-branch diff, conflict warnings), `ConflictResolverViewModel` (in-app **Rider-style 3-pane merge editor** for both single-task and planning unit-merge conflicts: single-task starts the conflict merge, parses each conflicted file into stable/conflict `MergeFileSegment`s via the worker's `GetMergeConflictDocuments`; exposes the active file's three reconstructed documents — `ActiveOursText` / `ActiveResultText` / `ActiveTheirsText` (from `MergeFile.OursText/ResultText/TheirsText`; Result seeds unresolved conflicts with Ours) — plus `ActiveFile`/`SelectFileCommand` (multi-file switcher), `Current`/`Next`/`Previous` (focused-conflict nav), a per-active-file `PositionText` readout, per-block `AcceptOurs/Theirs/Both/Base` + `MergeFile.Compose`, and `CanContinue` gated on every file resolved + no binary; writes each file via `WriteConflictResolution`, continue/abort; **planning mode** via `OpenForPlanningAsync(parentId, subtaskId)` loads the current subtask's mid-merge conflicts without re-starting the merge and routes continue/abort to `ContinuePlanningMerge`/`AbortPlanningMerge`, so a unit-merge conflict re-opens the editor per subtask via the `PlanningMergeConflict` broadcast). The view (`Views/Conflicts/ConflictResolverView`) shows the whole file in three **AvaloniaEdit** panes — MAIN/ours (read-only) | editable Result | INCOMING/theirs (read-only) — with TextMate highlighting by extension (theme `StyleInclude` in `App.axaml`); a code-behind `IBackgroundRenderer` tints each conflict block (unresolved/resolved) across panes, an `IReadOnlySectionProvider` + `TextAnchor` regions keep only conflict spans editable in Result (edits flow back to the block); each unresolved conflict starts EMPTY (a thin marker bar); the between-pane gutter controls **toggle** each side in/out of the result — `›`/`‹` add MAIN/INCOMING in click order (first pick on top), clicking again removes that side — so a conflict can take main, incoming, both, or neither; a `FilesSummary` readout shows how many files still have conflicts, and the three panes share a proportional synced vertical scroll. A conflict overview ruler right of the Result pane (`ConflictMap`) maps every conflict in the file proportionally (click a tick to jump) — handy for long files. Conflict block tints live in `Tokens.axaml` (`Merge*TintBrush`). The editor is reached from review **Approve** on conflict and from the **Merge** button in the Diff window (a conflicting `MergeTask` hands off to the resolver via `RequestConflictResolution`).
+- **Modal VMs** — `SettingsModalViewModel` (four tabs: General, Worktrees, Files prompt-paths, Prime Claude incl. `DailyPrepMaxTasks` + prime-schedule rows), `ListSettingsModalViewModel` (name, working dir, commit type, delete list; hosts shared `AgentConfigEditorViewModel` as `Agent` property (scope=List) — save delegates to `Agent.SaveAsync()`), `RepoImportModalViewModel` (bulk-create lists from git repos found under chosen parents; already-wired repos disabled), `WeeklyReportModalViewModel` (range pickers default "since last standup weekday → today", cached per range, markdown via MarkdownView), `MergeModalViewModel` (single-task merge form, called from the diff modal), `WorktreesOverviewModalViewModel` (global/per-list worktree rows, batch merge + state ops), `UnfinishedPlanningModalViewModel` (Resume/FinalizeNow/Discard for a draft planning session), `WorkerConnectionModalViewModel` (offline help), `AboutModalViewModel`, `LogVisualizerViewModel` (worker logs, last 30 min, all levels + a warn/error-only filter; loads via `GetRecentLogsAsync`).
+- **Diff stack** — `UnifiedDiffParser` (static; parses `git diff` output into `DiffFileViewModel`s, detecting added/deleted/renamed/binary files and per-line numbers; `Flatten` injects file-header rows for a combined single-pane view). `DiffModels.cs` holds shared types: `DiffLineViewModel`, `DiffFileViewModel`, `DiffLineKind`, `DiffFileStatus`, `SubtaskDiffRow`, `DiffTreeNodeViewModel`, `DiffTree`. `DiffViewerViewModel` is a single unified read-only diff viewer with two modes: **Files** (dirty worktree / branch-vs-base / commit-range — loads via GitService, shows a folder file-tree on the left + per-file diff pane on the right, Merge button for live branch source) and **Planning** (per-subtask diffs via `GetPlanningAggregateAsync`, subtask list left + flat diff right, combined integration-branch toggle). The Merge button opens the merge form, which routes to `ConflictResolverViewModel` on conflict. `DiffLinesView` renders per-file diff content with binary/empty placeholders.
+- **Conflicts** — `ConflictResolverViewModel` (in-app **Rider-style 3-pane merge editor** for both single-task and planning unit-merge conflicts: single-task starts the conflict merge, parses each conflicted file into stable/conflict `MergeFileSegment`s via the worker's `GetMergeConflictDocuments`; exposes the active file's three reconstructed documents — `ActiveOursText` / `ActiveResultText` / `ActiveTheirsText` (from `MergeFile.OursText/ResultText/TheirsText`; Result seeds unresolved conflicts with Ours) — plus `ActiveFile`/`SelectFileCommand` (multi-file switcher), `Current`/`Next`/`Previous` (focused-conflict nav), a per-active-file `PositionText` readout, per-block `AcceptOurs/Theirs/Both/Base` + `MergeFile.Compose`, and `CanContinue` gated on every file resolved + no binary; writes each file via `WriteConflictResolution`, continue/abort; **planning mode** via `OpenForPlanningAsync(parentId, subtaskId)` loads the current subtask's mid-merge conflicts without re-starting the merge and routes continue/abort to `ContinuePlanningMerge`/`AbortPlanningMerge`, so a unit-merge conflict re-opens the editor per subtask via the `PlanningMergeConflict` broadcast).

 - "Run Now" CanExecute re-evaluates when worker connection state changes
 - Icon gotcha: `PathIcon` fills geometry. Line-art/stroke icons must be defined as filled geometry or rendered as a stroked `Path` (e.g. `Icon.PlanDay` via the `Path.plan-icon` style); a pure stroke path used with `PathIcon` is invisible.
 - `SessionTerminalView` is the reusable log terminal (StyledProperties `Entries`, `Label`, `IsRunning`, `IsDone`, `IsFailed`) used for both the task `Log` and the prep `PrepLog`.
+- `DetailsIslandView` is a pane-wide drag-and-drop file target (`DragDrop.AllowDrop`, Avalonia 12 `DataFormat.File`) with a "Drop to attach" hover overlay. `DescriptionStepsCard` shows an Attachments list (file name, size, remove button), an "Add file…" picker, and an explicit `DropStatus` confirmation line. Keys use the `details.attachments.*` localization namespace (en + de).
