horizontal padding is `6`. +- Tab spacing is `0`. +- Tab corner radius is `0`. +- Active tab indicator height is `2`. +- Icon size is `14`. +- Title font size is `11`. +- Close button size is `16`. +- Close icon size is `9`. +- Dirty-indicator size is `8`. +- Notification-badge size is `6`. +- Content spacing inside a tab is `6`. +- Drop-indicator width is `2`. +- Drop-indicator height is `20`. +- Divider thickness is `1`. +- Minimum pane width is `100`. +- Minimum pane height is `100`. +- Split-action buttons remain in the pane chrome and preserve current iconography, hover states, pressed states, tooltips, and visibility rules. +- Minimal-mode behavior remains unchanged, including the 30-point top interaction strip and hover-driven action visibility. + +## Color Contract + +- With no custom chrome background, chrome colors match the current native system color behavior. +- With a custom chrome background, text color flips between dark and light treatment based on background luminance. +- Active text uses alpha `0.82`. +- Secondary or inactive text uses alpha `0.62` on dark-text treatment and `0.68` on light-text treatment. +- Active tab background is the chrome background darkened by `0.065` for light chrome or lightened by `0.12` for dark chrome. +- Hovered tab background is the chrome background darkened by `0.03` for light chrome or lightened by `0.07` for dark chrome, then shown with alpha `0.78`. +- Derived separator color uses alpha `0.26` for light chrome or `0.36` for dark chrome. +- Dirty indicators use the active text color at alpha `0.72` when custom chrome is active. +- Notification badges use the current blue accent treatment. +- Drop indicators use the current accent-color treatment. + +## Tab Behavior + +- Tabs inside a pane are ordered and stable. +- Pinned tabs always occupy a contiguous block at the front of the pane. +- Unpinned tabs always appear after the pinned block. +- Reordering must preserve the pinned and unpinned partition. +- Creating a pinned tab inserts it at the end of the pinned block. +- Creating an unpinned tab inserts it after the currently selected tab when the current new-tab policy applies, otherwise at the end of the unpinned block. +- Selecting a tab selects it in its pane and focuses that pane. +- Programmatic selection and user-driven selection must produce the same final state. +- Closing the selected tab picks the tab that moves into the same slot when possible, otherwise the previous tab if the closed tab was last. +- Tab metadata includes title, custom-title state, icon or icon image, kind, dirty state, unread state, loading state, and pinned state. +- Tab switching must preserve underlying panel state, including terminal state, browser state, markdown scroll state, find state, and developer-tools state. +- Only the selected tab in a pane may be visible and interactive. +- Non-selected content may not remain visually visible above the selected content. +- Non-selected content may not intercept drag, drop, hit-testing, or keyboard focus meant for the selected content. + +## Tab Context Menu Contract + +- The tab context menu supports rename. +- The tab context menu supports clearing a custom name. +- The tab context menu supports close to left. +- The tab context menu supports close to right. +- The tab context menu supports close others. +- The tab context menu supports move. +- The tab context menu supports move to left pane when such a destination exists. +- The tab context menu supports move to right pane when such a destination exists. +- The tab context menu supports creating a new terminal to the right. +- The tab context menu supports creating a new browser to the right. +- Browser tabs expose reload. +- Browser tabs expose duplicate. +- Tabs expose toggle pin. +- Tabs expose mark as read and mark as unread, gated by current unread state. +- Tabs expose toggle split zoom when the workspace has more than one pane. +- Context-menu shortcut hints remain synchronized with customizable keyboard shortcuts. + +## Pane Behavior + +- A pane shows its tab strip, its selected content, and any pane-local overlays. +- Clicking content inside a pane makes that pane the focused pane. +- A focused pane visually matches the current focused-pane treatment. +- An unfocused pane visually matches the current unfocused-pane treatment. +- Pane-local unread rings and attention flash effects preserve current behavior. +- Empty panes remain user-visible and actionable. +- An empty pane offers the same entry actions as today, including creating a terminal or browser in that pane. + +## Split Behavior + +- A split is always either horizontal or vertical. +- Horizontal means side-by-side, first pane on the left and second pane on the right. +- Vertical means stacked, first pane on top and second pane on bottom. +- New user-created splits begin at a `0.5` divider ratio. +- Programmatic divider updates clamp to the inclusive range `0.1...0.9`. +- Divider movement updates geometry snapshots and layout persistence. +- Closing a pane collapses the tree by promoting its sibling. +- After pane close, focus moves to the surviving sibling when possible, otherwise the first remaining pane. +- Split creation from pane chrome preserves the current behavior of seeding a terminal in the new pane. +- Split creation by moving an existing tab preserves that tab's metadata, panel identity, and panel state. +- Dragging the only tab from a pane to create a split must not leave behind a placeholder tab or a pane with no real panel mapping. +- Adjacent-pane navigation remains geometry-driven. +- If no pane exists in the requested direction, pane navigation is a no-op. +- When more than one candidate exists in a direction, the chosen pane is the one with the strongest perpendicular overlap, then the shortest distance. + +## Split Zoom Behavior + +- Split zoom is unavailable when the workspace has only one pane. +- Toggling split zoom on a pane shows only that pane in the workspace content area. +- Toggling split zoom again restores the prior split tree and divider ratios. +- Split zoom does not destroy panel state. +- Split zoom does not change tab ordering. +- Split zoom does not leave stale content, stale portal layers, or stale pane chrome visible after entering or exiting zoom. +- The selected tab in the zoomed pane shows the current zoom indicator treatment. + +## Drag and Drop Contract + +- Tabs can be reordered within a pane. +- Tabs can move across panes inside the same workspace. +- Tabs can move across workspaces and windows. +- Dropping on a pane center inserts into that pane. +- Dropping on a pane edge creates a split on that edge and places the tab in the new pane on the correct side. +- Dropping after the last tab in a tab strip inserts after the last tab. +- Dragging a tab over trailing empty space in a short tab strip still permits an after-last insertion. +- Inactive workspaces may remain mounted for state preservation, but they must not accept or steal drag interactions. +- File drops from outside the app onto a pane's content area target the currently selected terminal panel in that pane. +- Tab drags and sidebar reordering drags remain distinct and may not be confused with each other. +- Drag and drop may not violate pinned-tab ordering rules. + +## Focus Contract + +- Focused pane state, selected tab state, and AppKit first responder must converge. +- Visual selection may not drift away from actual keyboard target. +- Explicit pane focus changes focus the selected tab's panel in that pane. +- Explicit tab selection focuses that tab's pane and panel. +- Focus changes caused by socket or automation commands may only change in-app focus for commands that are explicitly focus-intent commands. +- Non-focus automation commands may not steal macOS app activation or window activation. +- Terminal focus, browser focus, omnibar focus, browser find focus, and terminal find focus must preserve their current behavior. +- Switching away from a browser tab must hide its visible browser surface. +- Switching away from a terminal tab must prevent stale terminal focus from stealing first responder back. + +## Panel-Specific Contract + +- Terminal panels preserve terminal process state, scrollback state, selection state, find state, and runtime font zoom state across tab switches, splits, zoom, and pane resizes. +- Terminal overlays, including find UI and unread or flash effects, remain correctly layered during split churn. +- Browser panels preserve URL, history stacks, profile, page zoom, developer-tools visibility intent, inline focus state, and current web content across tab switches, splits, zoom, and pane resizes. +- Browser panels may not remain visible when deselected. +- Markdown panels preserve their file-backed content and current viewing state across tab switches, splits, zoom, and pane resizes. + +## Persistence Contract + +- Session snapshots preserve workspace title, custom title, custom color, pinned state, current directory, focused panel, split tree, divider positions, pane membership, selected panel per pane, panel metadata, status entries, log entries, progress, and git-branch state. +- Terminal panel snapshots preserve working directory and eligible scrollback. +- Browser panel snapshots preserve URL, profile, page zoom, developer-tools visibility, render intent, and back and forward history. +- Markdown panel snapshots preserve file path. +- Session restore rebuilds the same pane tree, same divider ratios, same tab ordering, same selected tab per pane, same focused panel when available, and same panel metadata. +- Session restore skips automatic restore in the same cases as today, including explicit launch arguments and automated-test launches. + +## Automation Contract + +- The workspace exposes a layout snapshot containing container frame, pane frames, selected tab per pane, tab IDs per pane, focused pane ID, and timestamp. +- The workspace exposes a tree snapshot containing the recursive split tree, split orientations, divider ratios, pane frames, tab titles, tab IDs, and selected tab ID. +- Pane and tab IDs stay stable enough for the current automation and persistence layers to address them within a session. + +## Rewrite Guardrails + +- The replacement must preserve current user-visible behavior before it introduces any new behavior. +- The replacement may not rely on placeholder tabs as a steady-state concept. +- The replacement may not regress focus correctness, drag correctness, resize correctness, or session restore correctness. +- The replacement may choose any implementation strategy as long as every behavior above remains true.

Runtime tab chrome truth no longer depends on it. + +## Problem + +The current workspace layout path has too many runtime models and too many translation boundaries. + +A single user action such as split, close, move, rename, or focus currently crosses AppDelegate, TabManager, Workspace, WorkspaceLayoutController, SplitViewController, and the AppKit host. Runtime state is duplicated between panel dictionaries in `Sources/Workspace.swift`, tab metadata in `Sources/WorkspaceSplit.swift`, and renderer-local snapshots in `Sources/WorkspaceSplitNativeHost.swift`. That duplication is the main source of stale tab chrome, focus churn, and brittle feature work. + +## Constraints + +- Keep the workspace shell in AppKit. +- Support all current and planned surface kinds: terminal, browser, markdown, file editor, VNC, embedded simulators, and similar primitives. +- Keep Ghostty-backed terminals. +- Do not require every surface implementation to be AppKit-only. +- Do not rewrite the app around a large framework such as TCA. +- Do not change user-visible workspace behavior in the first migration steps. + +## Original Pain Points + +### Duplicated chrome state + +Before this migration, `TabItem` in `Sources/WorkspaceSplit.swift` stored title, icon, loading, unread, pinned, and related chrome state, even though the real source of truth already existed on the surface or panel owned by `Workspace`. + +### Parallel identity systems + +Before this migration, `Workspace` maintained `surfaceIdToPanelId` in `Sources/Workspace.swift`. That meant normal operations translated between layout IDs and panel IDs instead of operating on one canonical identity. + +### Renderer observes nested mutable state directly + +Before the snapshot conversion, `WorkspaceLayoutRootHostView` in `Sources/WorkspaceSplitNativeHost.swift` depended on nested pane and tab observation for chrome rebuild timing. That made redraw behavior depend on mutation shape instead of an explicit render contract. + +### Content mounting is type-switched in the renderer + +`WorkspaceNativePaneContent` and the AppKit host special-case terminal, browser, and SwiftUI fallback content. That makes each new surface kind more expensive to add. + +### Layout and content responsibilities are mixed + +The layout tree owns tab order and selection, but it also owns tab chrome payload. The renderer mounts views, computes presentation state, and knows about content kind. That is too much coupling for the core workspace shell. + +## Design Principles + +### 1. One canonical workspace owner + +There should be one workspace-owned source of truth for: +- layout topology +- surface identity +- selected surface per pane +- focused pane +- zoomed pane +- per-surface chrome state + +The simplest first step is not to add a new wrapper store. It is to make `Workspace` become the canonical `@MainActor @Observable` owner of this state over time. + +### 2. Layout state and surface state are separate + +The split tree should know only layout facts: +- pane IDs +- ordered `SurfaceID`s in each pane +- selected `SurfaceID` per pane +- focus state +- split ratios and orientation + +It should not own title, icon, loading, unread, pinned, dirty, or custom-title state. Those belong to the surface model. + +### 3. AppKit shell, pluggable surfaces + +Workspace layout, split dividers, tab strip, drag and drop, focus routing, and hit testing stay AppKit. + +Individual surfaces can be: +- pure AppKit +- SwiftUI behind one hosting adapter +- mixed wrappers such as Ghostty terminal or WKWebView browser + +This keeps the shell deterministic while allowing surface-specific implementation freedom. + +### 4. Snapshot-driven shell rendering, retained native surfaces + +The AppKit host should render the shell from immutable snapshots. It should not depend on nested observation over mutable pane and tab collections. + +But live native surfaces are not snapshot data. Ghostty surfaces, WKWebViews, and similar retained views should live in a separate retained registry keyed by `SurfaceID`. The snapshot tells the shell what should be visible and where it should be. The retained registry owns the real `NSView` objects. + +### 5. State is synchronous and main-actor owned + +Workspace mutation and rendering should stay on `@MainActor`. Per the SwiftGuidanceSkill guidance, UI state should use Observation-era models and explicit ownership, not scattered callback glue or GCD hops. + +Heavy non-UI work can still happen off-main, but the workspace shell itself should have a single synchronous state boundary. + +### 6. Focus is a separate imperative subsystem + +The snapshot can describe intended focus. Actual `firstResponder` changes still need explicit imperative focus APIs. Focus should not depend on incidental redraw or remount behavior. + +## Proposed Target Architecture + +### Workspace runtime store + +Use `Workspace` as the initial canonical `@MainActor @Observable` runtime store.

Our problem is not that we use AppKit. Our problem is that we have duplicated state and heterogeneous surface kinds. + +AppKit is still the better shell for desktop split layout, hit testing, drag and drop, portal-hosted views, and future complex primitives. + +### Simpler than forcing every surface into AppKit + +The workspace shell should be AppKit. Surface internals do not all need to be AppKit. A markdown editor or settings-like surface can still live behind one hosting adapter if that is the lowest-complexity implementation. + +## Alternative Approaches Rejected + +### 1. Keep the current model and patch invalidation harder + +Rejected because it keeps duplicated state and translation tables. It may hide symptoms, but it does not simplify the design. + +### 2. Make the full workspace shell SwiftUI + +Rejected because cmux is not just a terminal split tree. We need deterministic desktop behavior for drag, focus, portals, and mixed hosted content. + +### 3. Rewrite around a large reducer framework + +Rejected because the main problem is state shape, not lack of a framework. Plain `@Observable` models and immutable render snapshots are enough. + +## Migration Plan + +### Phase 1. Collapse identity first, completed + +Add `SurfaceID` as the canonical runtime identity everywhere layout code currently uses a separate tab identity. In the first cut, `SurfaceID` should be the panel identity, or a thin wrapper around it. + +The main goal of this phase is to delete `surfaceIdToPanelId` from normal layout operations as early as possible. This phase also needs a session and restore audit, because persisted layout snapshots currently depend on the old identity path. + +### Phase 2. Write down invariants, completed + +Before deeper refactors, define the exact invariants for: +- focus +- visibility +- empty panes +- detach and restore +- cross-workspace transfer + +This prevents the migration from merely relocating ambiguous behavior. + +### Phase 3. Move chrome truth out of layout, completed for runtime chrome + +Change pane state so panes store ordered `SurfaceID`s and selected `SurfaceID`, not `TabItem` payloads. + +The layout algorithms stay the same. Only ownership of title, icon, loading, unread, pinned, and dirty moves to `SurfaceModel.chrome`. + +### Phase 4. Make retained surface lifetime explicit, completed + +Use `Workspace.panels` as the provisional retained surface registry and make surface lifetime rules explicit. + +The goal is to preserve live terminal and browser objects across layout changes while moving shell state out of the renderer. Add a separate `RetainedSurfaceRegistry` type only if the simpler ownership shape later proves insufficient. + +### Phase 5. Add shell snapshot projection, completed + +Add one projection layer from `Workspace` to `WorkspaceRenderSnapshot`. + +This is the key seam. It gives us one render contract and one place to reason about visible shell state. + +### Phase 6. Convert the AppKit host to snapshot application, completed + +Refactor the AppKit host to: +- stop observing nested pane tab metadata directly +- stop computing business decisions in tab views +- apply pane and tab changes from snapshots only +- ask the retained surface lifetime owner, initially `Workspace.panels`, to update live surface views imperatively + +At the end of this phase, stale UI bugs should reduce to either a bad snapshot or a bad apply step. + +### Phase 7. Normalize surface mounting boundaries, completed for the current shell + +Keep `Panel` as the initial surface boundary. Add thin mounting adapters only where a panel needs extra host-specific behavior. + +Only introduce a new surface protocol if the simplified `Panel` boundary still proves inadequate after the ownership cut. + +### Phase 8. Flatten command flow, completed for active callers + +Flatten the current command flow so split, close, move, rename, and focus operate through one workspace command boundary. + +The likely end state is: +- AppDelegate resolves shortcut intent +- `Workspace` executes command +- `Workspace` mutates state +- renderer applies new snapshot +- focus and retained-surface visibility update imperatively + +This keeps TabManager and other compatibility layers thinner over time. + +### Phase 9. Delete old translation and invalidation paths, completed for this migration + +Remove: +- `TabItem` as the runtime source of chrome truth +- `surfaceIdToPanelId` for normal layout operations +- renderer-local type switches as the main content extension point +- old observation-based rerender hooks that exist only to compensate for duplicated state + +## Browser and Future Surface Kinds + +### Browser + +Browser portal and visibility assumptions now live behind the browser's retained surface entry and mounting adapter instead of leaking into the layout host. + +If browsers eventually move to a different engine, this architecture still holds. The shell continues to mount one surface by `SurfaceID`. + +### Future primitives + +Editors, VNC, simulators, and similar views fit this model cleanly. They each provide: +- a surface model +- a retained surface entry +- chrome state +- focus and visibility hooks + +No new layout architecture is needed per surface kind. + +## Risks + +### Risk 1. Migration churn + +This touches core workspace behavior. The migration must keep user-visible behavior stable and land in phases. + +### Risk 2. Focus regressions + +Focus is still the trickiest part of the current code. Each phase needs explicit invariants and behavior checks. + +### Risk 3. Snapshot bloat + +Do not let `WorkspaceRenderSnapshot` become a dumping ground. It should contain only the data the shell renderer needs to draw and place chrome. + +### Risk 4. Retained-surface churn + +If the retained lifetime owner remounts terminals or browsers too aggressively, the architecture still fails. Surface lifetime must stay stable across selection, split, and zoom changes. + +### Risk 5. Placeholder and transfer semantics + +The current split logic still depends on placeholder and detach-transfer behavior. Identity collapse and snapshot projection must account for empty-pane creation, detach, attach, and restore semantics explicitly. + +## Verification Strategy + +Prefer behavior-level verification: +- split right and split down +- close selected surface +- move surface between panes +- rename surface +- unread, loading, dirty, and pinned state updates +- focus changes between panes and surfaces +- browser and terminal visibility correctness during drag and close +- detach and restore behavior +- startup and restore behavior after the main architecture cutovers + +Add deterministic unit coverage around: +- pure layout state transitions +- shell snapshot projection +- command reducers or command handlers +- retained-surface registry decisions + +Do not add source-shape tests. + +## Recommended First Implementation Slice + +The first slice should be the highest-leverage cut with the lowest behavior risk: +- make `SurfaceID` the only runtime identity used by layout +- move tab chrome payload out of `TabItem` +- add a shell-only `WorkspaceRenderSnapshot` +- use `Workspace.panels` as the provisional retained surface registry +- keep `Workspace` as the initial canonical owner instead of adding a wrapper store +- keep `Panel` as the initial surface boundary unless it proves insufficient +- audit session restore, detach, and transfer paths during identity collapse + +That slice removes the worst duplication without forcing an all-at-once rewrite.

`WorkspacePaneMountIdentity`, with per-kind retained host adapters behind it instead of parallel browser, markdown, and placeholder host stores +- retained-surface mounts no longer receive `selectedTabId` from the old per-tab host path, because each pane now mounts only one workspace-selected content payload +- pane-host content refresh now compares explicit mount identity before reuse, so content-kind transitions tear down deterministically instead of relying on `installContentView` side effects +- off-window terminal mounts now keep the hosted view installed immediately and only defer the runtime `attachSurface` step until a real window-backed refresh, which removes the blank-pane root-collapse failure during split close +- regression coverage now checks the new

edge operations. +4. done, first-responder scheduling now goes through one `@MainActor` per-window owner coordinator (`GhosttyWindowFocusCoordinator`) with a generation token. +5. done, focus scheduling moved from `DispatchQueue.main.async` coalescing to structured `Task { @MainActor }` with cancellation and generation checks. +6. done, new pure transition/presentation structs are value types with explicit `Sendable` conformance where appropriate. +7. done, deterministic tests now cover the new transition resolver plus split/close and child-exit behavior. `cmux-unit` targeted run passed with `13` tests and `0` failures (`WorkspaceContentViewVisibilityTests`, selected `WorkspaceUnitTests` split-close cases, and `TabManagerChildExitCloseTests`). + ## Status Implemented on

pane-host content refresh now compares explicit mount identity before reuse, so content-kind transitions tear down deterministically instead of relying on `installContentView` side effects - off-window terminal mounts now keep the hosted view installed immediately and only defer the runtime `attachSurface` step until a real window-backed refresh, which removes the blank-pane root-collapse failure during split close - regression coverage now checks the new retained-surface contract directly, including off-window terminal mounting, shared-slot content replacement, workspace-selected displayed content, placeholder mounting, terminal-host detachment on surface removal, and later attachment after the host enters a window +- retained-surface regression coverage now also directly checks browser and markdown mount, remount reuse, and unmount behavior through `WorkspaceSurfaceRegistryTests`, so every currently supported surface kind is exercised through the new viewport path - `Workspace` now conforms to the `WorkspaceLayoutHost` protocol directly, so production rendering no longer stores or passes a `WorkspaceLayoutController` bridge through `Workspace` and `WorkspaceContentView` - the AppKit layout host now talks to `Workspace` through that host protocol for geometry, drag, split, close, zoom, context action, file-drop, and external-tab-drop routing - `WorkspaceLayoutControllerHostAdapter` is gone, because the native tab-button leaf now receives explicit action closures for select, close, zoom, context actions, and drag lifecycle instead of retaining the full host protocol just for preview and debug wiring From f337746f9c518349ec5a5d23d69ae419779657f6 Mon Sep 17 00:00:00 2001 From: Lawrence Chen Date: Fri, 17 Apr 2026 02:10:05 -0700 Subject: [PATCH 051/154] terminal: centralize viewport lifecycle ownership --- Sources/AppDelegate.swift | 61 +- Sources/GhosttyTerminalView.swift | 685 +++++++++++++------ Sources/TabManager.swift | 40 +- Sources/TerminalController.swift | 13 +- Sources/Workspace.swift | 106 +-- Sources/WorkspaceSplitNativeHost.swift | 81 ++- cmuxTests/WorkspaceUnitTests.swift | 245 +++++++ docs/workspace-layout-simplification-plan.md | 78 +++ 8 files changed, 1001 insertions(+), 308 deletions(-) diff --git a/Sources/AppDelegate.swift b/Sources/AppDelegate.swift index 2dc906c0eaf0..ee18bb05e525 100644 --- a/Sources/AppDelegate.swift +++ b/Sources/AppDelegate.swift @@ -7693,15 +7693,15 @@ final class AppDelegate: NSObject, NSApplicationDelegate, UNUserNotificationCent } var resolved = false -
