One window. The panes follow the "UI layout" rules in `AGENTS.md`: an `HStack` of two panes of exactly equal width at every size, no sidebar, no navbar, nothing above them but the identity banner when the user has no git identity. The title bar is the standard one; no byre controls go in it or in a toolbar.

Overlays (the switcher, alerts, confirmations, the merge dialog, keyboard help) are SwiftUI views drawn above the panes inside the window, not system sheets or alerts. The switcher and the Discard confirmation sit just below their anchor; the merge dialog is centred in the right pane.

## Views
- **Transcript and Lead.** `TranscriptBuilder` is a pure function from events to a list of rows: user and agent messages, consecutive tool calls folded into one group with its summary ("Read file ×3"), subagents nested with their status, pending tool calls and running subagents (background ones included after the turn ends) outlined in the accent colour with a 0.6s fade, thinking, the byre prompt collapsed, held turns, `NO_REPLY` turns folded away, handoffs, snapshot rows with changes, fork and review, and notes for the other event kinds. It is incremental: a new batch extends the existing rows. The view is a `ScrollView` with a plain `VStack`, stuck to the bottom unless the user has scrolled more than 80 points up. The stack isn't lazy because a `LazyVStack` estimates the height of rows it hasn't shown yet and corrects it when they scroll into view, without moving the scroll offset, so scrolling up through rows not yet shown jumped by each correction; SwiftUI can't move the offset mid-scroll without stopping its momentum. While the user is scrolling (`onScrollPhaseChange`), content height changes only update whether it is stuck and never pull it back to the bottom. The lead pages back when the view comes within one screen of the top: the fetched page is held while the scroll phase is scrolling and inserted once it is idle (`ChatModel.older`, `prependOlder`), and the next geometry change moves the offset down by the height added, so the rows on screen stay put; a page that adds no rows (all folded `NO_REPLY` turns) fetches the next one at once. Each Markdown text run's `NSTextView` measures its height with one TextKit stack kept in its coordinator, and a repeat measurement at the same width and text returns the stored size. Pending sends show at the end until the server echoes them. A turn summary counts as read when its row is on screen and the app is active (`markSummaryRead`). The head carries Compact (with its context-usage fill; a long press opens a menu of models to continue on), Sync from main, Merge and Discard.

- **Composer.** A `TextEditor`, with paste and drop handled as in "Gaps in SwiftUI". Text, the model menu (filtered to the live session's vendor), Interrupt and Send. Enter sends, Shift-Enter adds a newline, and Enter during IME composition does neither. Pasted or dropped PNG, JPEG, GIF and WebP images become thumbnails with ×, uploaded to `POST /api/blobs` on send; any other image `NSBitmapImageRep` decodes, such as TIFF, is converted to PNG first, its size checked after conversion. A failed send puts the text and images back and shows the error.
- **Inbox.** The selected task's oldest open item, rendered from its Markdown context with each choice's marker replaced by a clickable block (pick-one, sends at once) or checkbox (pick-any, with Submit), the "recommended" tag, image-choice grids, attachments, Let the agent decide, Other… and, for errors, Reply… and Dismiss. Arrow keys move between choices. A 409 shows its error. The Changes summary line sits above it.
- **Questions.** The question a transcript bubble picked (`Store.question`), read-only once it is no longer open, or else the selected task's oldest open item, rendered from its Markdown context with each choice's marker replaced by a clickable block (pick-one, sends at once) or checkbox (pick-any, with Submit), the "recommended" tag, image-choice grids, attachments, Let the agent decide and Other…. Arrow keys move between choices. A 409 shows its error. The Changes summary line sits above it.
- **Changes, Files, Reviews, Workflow, Project, Status, Settings.** Including the pinned-snapshot stepper, open-diff memory, per-task place in Files, finding diffs with Fix and Ignore, nested subtasks, TODO Start and Discuss, rate-limit pace bars and lead notes. The Workflow tab draws its stage graph natively from the `WorkflowRun` (stages as boxes coloured by state, `after` as edges, laid out top to bottom by depth) with the layout and drawing code from "Diagrams", fed from the run's data rather than Mermaid text.
- **Terminal.** A terminal view attached to `GET /api/tasks/{taskId}/terminal` with `URLSessionWebSocketTask`: binary input and output, `TerminalSize` JSON on resize, close code 4000 for `shell ended: <status>` with New shell, 1011 for a start failure, reconnect after 2 s while the task is active, one socket per open tab and selected task. Colours come from the palette. Ctrl combinations typed in it go to the shell. The cursor is a steady block (`setCursorStyle(.steadyBlock)` when the view is made): SwiftTerm's blinking cursor restarts its Core Animation fade on every keypress, scheduled 0.7 s out, and on a ProMotion (variable refresh rate) display macOS then holds the window's screen update until that fade starts, so each typed letter appears about 0.7 s late. A program in the shell can still ask for a blinking cursor with DECSCUSR.
- **Switcher.** The ⌘K overlay, also opened by clicking the task picker, centred below the picker: tasks with inbox items first, then least recently visited, the selected task last, the `name: title` project prefix, New task, Start in …, Start workflow… and its second step, projects, Escape stepping back, and the list scrolling to keep the highlighted row in view. Picking a task opens its Inbox when it has items, its unread summary when it has one, and its Transcript otherwise.
- **Merge and Discard.** The transcript head's Merge button is enabled once `GET /api/tasks/{taskId}/unmerged` reports commits or files, refetched 1.5 s after a tool result or turn end. `confirmMerge` (`MergeDialog.swift`): the editable commit title (at most 72 characters, kept across a warning link's detour), co-authors, warnings that refetch on the task's snapshot and review events and link to the Reviews or Inbox tab, the parent-or-default-branch choice for subtasks, and Merge now / After review while the latest snapshot's review is running. It is centred in the right pane. Discard confirms below its button, then clears the focused task.
