Merge remote-tracking branch 'origin/main'

Die oberste Sidebar-Ebene ist jetzt eine gemischte TopLevel-Collection, so
dass eine Liste auch oberhalb eines Ordners stehen kann. DropAsync deckt
alle vier Quelle/Ziel-Kombinationen ab, ReorderSidebarAsync numeriert die
gesamte sichtbare Reihenfolge ueber lists und list_folders hinweg.

   - `Number` (INTEGER NOT NULL, unique index `idx_tasks_number`) — a global, monotonically increasing display alias for tasks. **Never reused**: deleting a task leaves a gap in numbering, ensuring that a task number that appears in a log or report always points to the same task (if it exists). Allocated by `TaskNumberAllocator.AddWithNumberAsync` on every insert via a persistent counter (`app_settings.next_task_number`). **Why not `MAX(number) + 1`:** deleting the highest-numbered task would free its number for reuse, breaking the immutability guarantee. The allocator uses an `UPDATE…RETURNING` statement to claim numbers atomically, retrying up to 5 times if a uniqueness collision occurs (the counter advances on each attempt, so retries always allocate fresh numbers). The one-time backfill for pre-existing rows lived in the `AddTaskNumbers` migration, squashed away 2026-08-26.

+  - `FolderId` (`folder_id`, nullable FK → `list_folders.id`, `ON DELETE SET NULL`) — the sidebar folder the list sits in; null = top level. Written only by the UI (`ListsIslandViewModel` drag/context menu), never by MCP.
+- **ListFolderEntity** — Id, Name, Icon, SortOrder, IsCollapsed, CreatedAt → `list_folders`. A pure sidebar grouping: no tasks, no config, no working dir, **one level** (folders never nest). Deliberately its own table rather than a flag on `lists`, so every caller that enumerates lists (MCP `list_task_lists`, "move to list", the queue picker, repo import) needs no folder filtering. Folder CRUD lives on `ListRepository`.
 - **ListConfigEntity** — ListId (PK, 1:1), Model, SystemPrompt, AgentPath, MaxTurns, SessionSkills, VerifyCommand, PermissionMode, TicketProjectId (all nullable). `VerifyCommand` is an optional post-merge gate; null/blank = no gate → [review-merge](../../docs/explore-notes/review-merge.md). `PermissionMode` is null = inherit the global default; resolution order task → list → global lives in `EffectiveRunConfigResolver`. `TicketProjectId` (`ticket_project_id`) links the list to a project in the external ticket system; null = not linked → `ClaudeDo.Worker/CLAUDE.md` Tickets section.
   - ⚠️ `ListRepository.SetConfigAsync` copies the entity **verbatim**, so every writer must carry the fields it doesn't own (`SessionSkills`, `PermissionMode`, `TicketProjectId`) or they silently reset. `UpdateListConfigDto.TicketProjectId` is tri-state (`null` = keep stored) for exactly that reason — only the list-settings modal sends an explicit value. This bit `PermissionMode` for real: its update-branch copy was missing from `SetConfigAsync` until `f0a3a186`, so a list's permission-mode override only ever stuck on the list's *first* save, never on a later one.
 - **WorktreeEntity** — TaskId (PK, 1:1), Path, BranchName, BaseCommit, HeadCommit, DiffStat, MergeCommit (nullable — SHA of the merge commit this branch produced; the only thing making `revert_merge` possible without searching `git log`), State (`Active|Merged|Discarded|Kept`)

Every other creation path (UI, MCP `add_task`, `batch_add_tasks`, Online Inbox sync, merge-helper handler tasks, planning children) routes through one of these two.

+- **ListRepository** — CRUD, `GetConfigAsync`/`SetConfigAsync` (upsert)/`DeleteConfigAsync` for `list_config`, plus the `list_folders` set: `GetFoldersAsync`, `AddFolderAsync` (appends), `RenameFolderAsync`, `DeleteFolderAsync` (folder only — the FK releases its lists), `SetFolderCollapsedAsync`, `SetListFolderAsync`. The folder writers are `ExecuteUpdate` patches, not entity `Update()`s, so a rename can't reset `SortOrder`/`IsCollapsed` the way `SetConfigAsync`'s verbatim copy resets forgotten columns.
+  - ⚠️ **`lists.sort_order` and `list_folders.sort_order` share one number space** — the sidebar interleaves folders and top-level lists in a single order, so `ReorderSidebarAsync` numbers the whole visual sequence (each folder followed by its children) across both tables, and `AddAsync`/`AddFolderAsync` append via `MAX(sort_order)+1` over **both**. Never renumber one table on its own.
 - **WorktreeRepository** — CRUD, `UpdateHeadAsync`, `SetStateAsync`, `SetMergedAsync` (atomically sets State=Merged **and** stamps MergeCommit in one update — the only writer of MergeCommit)
 - **TaskAttachmentRepository** — `AddAsync`, `UpdateAsync`, `GetAsync(taskId, fileName)`, `ListByTaskIdAsync`, `DeleteAsync(taskId, fileName)`. Bulk delete-per-task is the `ON DELETE CASCADE` on `task_attachments`, not a repository method.

 - **IslandsShellViewModel** — root coordinator. Owns the three island VMs and the `WorkerClient`, wires cross-island events (selection, notes/prep mode, conflict resolution), connection state, the update banner, the inline worker-log strip (clickable → Log Visualizer overlay; `FlashFooterError` surfaces UI-action failures + the worker's Warn/Error there), responsive-layout flags (`ShowLists`/`ShowDetails` by window width), `PrimeStatus` flash, the modal openers, and `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`.
+  - **Folders:** the sidebar's top level is **one mixed collection**, `TopLevel` (`ObservableCollection<object>`: `ListFolderNavItemViewModel` rows, each with its own `Lists`, interleaved with folder-less `ListNavItemViewModel` rows) — that's what lets a list sit *above* a folder. `Folders`/`RootLists` are `OfType` **projections** of it, not collections to keep in sync. `UserLists` stays the **flat superset** every count refresh, row refresh and the no-repo banner work over — a row lives in both. `ContainerOf(row)` resolves which collection renders it (non-generic `IList`, since the top level is mixed). The view is a single `ItemsControl` over `TopLevel` with **implicit, type-matched `DataTemplate`s in `UserControl.DataTemplates`** — no keyed row template, and the folder's child `ItemsControl` resolves the same list template by walking up to the UserControl. A folder is never selectable: tapping the header runs `ToggleFolderCommand` (persisted to `list_folders.is_collapsed`), and its badge is the sum of its children. `DropAsync(source, target, placeBelow)` handles all four source/target combinations and doubles as the move: a drop position implies a container, so dropping a list onto a row in another folder — or next to *anything* at the top level, folder headers included — reassigns `FolderId`. A folder dropped onto a row inside a folder is ignored; folders never nest. `MoveToFolderAsync` is the drop-into-the-header path (reaches collapsed/empty folders, bound to the middle half of the header — the outer quarters insert *next to* the folder instead); `RemoveFromFolderCommand` is its context-menu counterpart. Both end in `PersistOrderAsync` → `ListRepository.ReorderSidebarAsync`, one `sort_order` sequence spanning **both tables**. ⚠️ A **folder** drag starts from `PointerMoved` past a 4px threshold using the *stored* `PointerPressedEventArgs` (`DoDragDropAsync` only accepts those) — starting it on press would capture the pointer and swallow the `Tapped` that folds the folder.
 - **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; planning session lifecycle; `RefineTask`, `OpenConPtySessionRequested`, `ToggleManual`, `SyncInteractiveSessions`; MyDay extras (`IsMyDayList`, `ClearDayCommand`, `ShowPrepLogCommand`) and the pinned Notes pseudo-row. Raises `NotesRequested`/`PrepRequested` for the shell.
 - **DetailsIslandViewModel** — the detail pane for a bound `TaskRowViewModel`. Owns live-log streaming (`Log` via `StreamLineFormatter`), debounced title/description editing, subtasks, the session-outcome/roadblock split, the three-tab work console (`output`/`git`/`session`), child surfacing (`ChildOutcomes` + `ChildrenNeedingAttention` drive an attention band on the Session tab), attachments, and the modes `IsNotesMode`/`IsPrepMode`/computed `IsTaskDetailVisible`. Failures raise `ErrorReported`, wired by the shell into `FlashFooterError`.
   - Three concerns are extracted into section VMs exposed as properties: `AgentSettings` (`AgentConfigEditorViewModel`, scope=Task), `MergeSectionViewModel`, `PrepPanelViewModel`. Helper rows live in the same file.

 | `SettingsModalViewModel` | Four tabs: General, Worktrees, Files (prompt paths), Prime Claude. General hosts the per-model preset table (`ModelPresetRowViewModel`: effort + max turns per alias) which **replaced** the single global "Max turns" field. The Prime Claude tab gives each schedule row a three-way action radio group (Ping / Fill My Day / Custom) — `RadioButton.GroupName` is bound to a **per-row** `RadioGroup` string, since a shared group name would make every schedule share one selection. `DailyPrepMaxTasks` is disabled unless some row is `FillMyDay`. |

There is no list↔folder conversion. Creating a folder writes a `list_folders` row and **deletes the list row the create flow pre-created**, reporting it as `Deleted` so the caller does a full reload. |

 | `UsageMonitorModalViewModel` | Opened from the usage pill (shown **before** the data loads via `BeginLoad`); gauges are **dynamic** per `UsageSnapshotDto.Limits` row, and the 5h/7d ones carry three draggable stage markers (soft/hard/gate) via `UsageGaugeBar` + the pure `UsageThresholdDrag`, plus a colour-matched legend with a `NumericUpDown` per stage → [usage-monitoring](../../docs/explore-notes/usage-monitoring.md). The **analytics** part (models/tasks/cost) comes from the external TokenTracker export, not from us: without the CLI the modal shows a hint card with an install button (gated on Node ≥ 20) instead of the totals header. Gauges, gate and throttle are unaffected by it. The modal is **display + threshold drag only** — the PowerUse switch/window/handoff % it used to host moved to Settings → Execution (`GeneralSettingsTabViewModel`), and "Refresh now" is an icon in the titlebar via `ModalShell.HeaderActions` rather than a body row. |

 ## Architecture
 
 - **Program.cs** — loads config, inits schema, registers DI, configures SignalR on `/hub`, binds to `127.0.0.1:47821`
-- **TaskStateService** — the **only** component that writes `Status`, `PlanningPhase`, `BlockedByTaskId`, and the `task_dependencies` edges. All transitions return a `TransitionResult` (no exceptions on invalid moves). Wakes the queue and advances the planning chain on child terminal transitions. Every transition broadcasts via a private `NotifyAsync(taskId)` — never call `_broadcaster.TaskUpdated` directly from this class, `NotifyAsync` also drives `TicketStatusSync.SyncAsync` (see Tickets below) and a direct call skips that transition's ticket write-back. `SetDependsOnAsync` replaces the task's whole dependency **set** (empty list clears it) and rejects a self-reference, an unknown dependency id, or any link that would create a cycle — a BFS over the whole `task_dependencies` edge set from every proposed predecessor, so a multi-edge loop (A→B→C→A) is caught too, and one bad edge leaves the entire set unwritten.
+- **TaskStateService** — the **only** component that writes `Status`, `PlanningPhase`, `BlockedByTaskId`, and the `task_dependencies` edges. All transitions return a `TransitionResult` (no exceptions on invalid moves). Wakes the queue and advances the planning chain on child terminal transitions. `SubmitForChildrenAsync` (Running → WaitingForChildren) also chains and immediately queues a normal parent's own Idle/Queued children via `PlanningChainCoordinator.SetupChainAsync(enqueue: true)` — unlike a planning parent (`PlanningPhase != None`), whose children stay untouched here and wait for the user's explicit "Queue plan" (`QueuePlanAsync`); a child already `Running` makes `SetupChainAsync` throw, which is caught and logged rather than failing the parent's own transition. Every transition broadcasts via a private `NotifyAsync(taskId)` — never call `_broadcaster.TaskUpdated` directly from this class, `NotifyAsync` also drives `TicketStatusSync.SyncAsync` (see Tickets below) and a direct call skips that transition's ticket write-back. `SetDependsOnAsync` replaces the task's whole dependency **set** (empty list clears it) and rejects a self-reference, an unknown dependency id, or any link that would create a cycle — a BFS over the whole `task_dependencies` edge set from every proposed predecessor, so a multi-edge loop (A→B→C→A) is caught too, and one bad edge leaves the entire set unwritten.
 - **IQueueWaker / IQueuePicker / QueueService** — waker is a singleton `SemaphoreSlim`; picker performs the atomic `Queued → Running` claim filtered by `BlockedByTaskId IS NULL`, `is_manual = 0`, schedule, and "no `task_dependencies` edge whose predecessor isn't `done`" (doubly negated on purpose: zero edges stays eligible, all edges must be done, and an edge pointing at a vanished task keeps blocking); QueueService is a thin `BackgroundService` looping on the waker, dispatching via `TaskRunner`. Per tick it also applies the usage throttle and gate → [usage-monitoring](../../docs/explore-notes/usage-monitoring.md).
 - **RunCancellationRegistry** — taskId → running-run CTS. Lets `TaskStateService.CancelAsync` kill a cancelled task's process without a DI cycle.
 - **OverrideSlotService** — owns `RunNow` / `ContinueTask`; goes through `TaskStateService.StartRunningAsync` (caller-driven, serialized by slot lock).
