 ## 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: **AgentConfigEditorViewModel** (scope=Task; per-task Model/MaxTurns/AgentPath overrides with `InheritedBadge` + `InheritanceResolver`, additive SystemPrompt, debounced auto-save; exposed as `AgentSettings`), **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`). 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, 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`.
+- **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). `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`).

The surface tracks `WorkerHub` (see `src/ClaudeDo.Worker/CLAUDE.md` for the canonical method/event list); groups: task execution (RunNow/Cancel/Continue/Reset/SetTaskStatus), review (`ApproveReviewAsync(taskId, targetBranch) -> MergeResultDto`, reject-to-queue/idle, cancel review, `PreviewMergeAsync -> MergePreviewDto`), planning sessions (start/resume/discard/finalize, queue subtasks, pending draft count, interactive terminal, refine), planning aggregate/integration-branch diffs, unit-merge continue/abort, single-task conflict resolving (start/get-conflict-documents/write-resolution/continue/abort), worktrees (overview, set state, force remove, cleanup, reset all), agents, app settings, lists/config, weekly report, daily notes, daily prep (`RunDailyPrepNowAsync`, `ClearMyDayAsync`, `GetLastPrepLogAsync`), prime schedules. Events mirror `HubBroadcaster` (task/worktree/list/run updates, prep events, planning-merge events, refine events, worker log). Lifecycle (`StartAsync`/`StopAsync`) and a few admin methods live only on the concrete `WorkerClient`.
