* Pre-launch app for browser UI test on headless CI runners
XCUIApplication.launch() blocks ~60s then fails on headless WarpBuild
runners because foreground activation requires a GUI login session.
Apply the same pre-launch strategy used for the display resolution test:
- CI shell launches the app with env vars before running xcodebuild
- Test detects pre-launched app via manifest, uses activate() instead of
launch() to avoid killing and relaunching the app
- Falls back to clicking the window for focus via accessibility framework

* feat: cmux.json for custom commands
* tests: add cmux json tests
* fix: pr review feedback: validation, translations, input handling, and palette improvements
- Fix Danish ("Overfladedef inition") and Norwegian ("rotmapp") translation typos
- Add empty-string check for baseCwd fallback in command palette handlers
- Coalesce \r\n into single Return keypress in sendInput
- Redact command text from timeout log to prevent secret leakage
- Add decode-time validation: reject hybrid/empty commands, ambiguous layout
nodes, wrong split children count, and empty pane surfaces
- Namespace custom command IDs with "cmux.config.command." prefix
- Forward command description to palette subtitle when available
- Update tests for new validation rules and ID prefix
* fix: address PR review feedback — per-window config isolation, blank validation, ancestor walk,
palette sanitization
* fix: fallback to current dir cmux.json watching if no any cmux.json found in full acesor walk
* ci: trigger CI for fork PR
* Add directory trust for cmux.json command confirmation
The confirm dialog now shows the actual command text and has an "Always
trust commands from this folder" checkbox. When checked, future confirm
commands from that directory skip the dialog.
Trust is scoped to the git repo root if the cmux.json is inside a repo,
so trusting once covers all subdirectories. Non-git directories are
trusted by exact path. Global config is always trusted.
Trusted directories are persisted in ~/Library/Application Support/cmux/
trusted-directories.json.
* Add trusted directories section to Settings
Shows all trusted directories with per-directory revoke buttons and a
Clear All option. Placed in a "Custom Commands" section between
Automation and Browser in Settings.
* Replace trusted directories list with editable textarea
One path per line, with a Save button that activates on changes.
Users can add, remove, or edit paths directly.
* Auto-save trusted directories on edit, remove Save button
Matches the behavior of other textarea settings (browser host
whitelist, external URL patterns) which auto-save via @AppStorage.
* Sanitize command text in confirm dialog against BiDi attacks
Strip zero-width and BiDi override characters from the command preview
so the dialog shows exactly what will be executed.

When pressing Cmd+N for a workspace number that doesn't exist,
the event was not consumed and fell through to Ghostty's goto_tab
binding, which could create a new window. Now the event is always
consumed when the digit matches, preventing unintended window creation.

* Fix browser portal leaking to other tabs on Bonsplit tab switch
When switching between Bonsplit tabs within a workspace, portal-hosted
WKWebViews from deselected browser panels could remain visible above the
newly selected tab. This happened because Bonsplit's keepAllAlive mode
hides non-selected tabs via SwiftUI .opacity(0), but the portal layer
renders at the AppKit window level and is not affected by SwiftUI
opacity changes.
Explicitly hide browser portals for deselected tabs in the pane during
tab selection, ensuring the portal visibility state is always in sync
regardless of SwiftUI re-render timing.

* Fix panel resize stuttering when tiled with browser panels (#1968)
During divider drag, the portal sync system was doing O(N²) work per
frame: each geometry callback synced ALL web views, and multiple
callbacks fired per layout pass (setFrameSize + setFrameOrigin + layout).
Two changes:
1. synchronizeWebViewForAnchor now only syncs the primary web view and
defers the all-sync. Each panel fires its own geometry callback, so
secondary syncs are redundant on the hot path.
2. HostContainerView.setFrameOrigin/setFrameSize use markGeometryDirtyIfNeeded
which defers the callback to layout(), coalescing 2-3 notifications
per frame into one. An async fallback ensures origin-only changes
(without a subsequent layout) are still delivered.

* Fix premature geometryRevision increment in markGeometryDirtyIfNeeded
Address reviewer feedback (Greptile, CodeRabbit): geometryRevision and
lastReportedGeometryState are now only updated when the callback
actually fires, not eagerly. This prevents updateNSView from seeing a
premature revision delta and triggering a redundant synchronizeForAnchor
before the coalesced notification arrives.

* fix: prevent Japanese IME confirmation Enter from executing command
Korean IME commits a syllable and executes on a single Enter, but
Japanese/Chinese IME use Enter only to confirm conversion — a second
Enter is needed to execute. Restrict the extra Return forwarding in
shouldSendCommittedIMEConfirmKey to Korean input sources only.
* refactor: use case-insensitive check for Korean input source ID
* Fix dock icon not auto-switching with system dark mode
The automatic icon mode relied on the asset catalog to handle
appearance-based icon selection, but the compiled Assets.car does not
include dark variant renditions for AppIcon. This meant setting
applicationIconImage to nil had no effect — the icon stayed on the
light variant regardless of system appearance.
Replace the nil-reset approach with an active KVO observer on
NSApp.effectiveAppearance that programmatically swaps between
AppIconDark and AppIconLight images when in automatic mode.

When MainWindowContext.window (weak var) becomes nil after extended
uptime, resolvedWindow(for:) falls back to windowForMainWindowId()
which searches NSApp.windows by identifier. However, the recovered
window was only assigned back to context.window without reindexing
the mainWindowContexts dictionary — leaving the ObjectIdentifier key
stale. Subsequent lookups via contextForMainTerminalWindow() would
miss the context, causing addWorkspaceInPreferredMainWindow() to
return nil and Cmd+N to fall back to opening a new window.
Call reindexMainWindowContextIfNeeded() when re-resolving a window
so the dictionary key matches the current NSWindow object.

* Export CMUX_SOCKET alongside CMUX_SOCKET_PATH in terminal environment
The app only exported CMUX_SOCKET_PATH when setting up the terminal
environment, but some scripts and hooks (e.g. claude-hook) expect
CMUX_SOCKET. The CLI launcher code already exports both (cmux.swift
lines 9288-9289), but the app-side terminal setup was missing the
alias. This caused claude-hook stop to fail with 'TabManager not
available' when CMUX_SOCKET was empty.

* Fix sidebar notification persisting after being read
latestNotification(forTabId:) fell back to latestByTabId when no
unread notifications existed, causing read notifications to persist
in the sidebar even after the user marked them as read, killed all
processes, or switched branches. The sidebar should only display
unread notifications.
Remove the fallback to latestByTabId so the sidebar notification
text clears once all notifications for a workspace are read.

* fix(browser): use native value setter for React/Vue/Angular compatibility
fill, type, and select commands set input values via direct property
assignment (el.value = x), which does not trigger state updates in
frameworks that override the value setter on element instances.
Use Object.getOwnPropertyDescriptor on the prototype to call the
native setter, which bypasses the framework override and allows the
subsequent input/change events to propagate correctly through
React's synthetic event system.
Affects: browser.fill, browser.type, browser.select
* walk prototype chain instead of instanceof for cross-realm and web component support

* Fix all split panes appearing focused after layout restoration
Ghostty C surfaces default to focused=true (Terminal.zig), but
TerminalSurface.lastFocusState was initialized to false. During
restoration, unfocus() is called before C surfaces exist (views not in
window yet), so the ghostty_surface_set_focus(false) call was silently
dropped. When surfaces were later created, the dedup guard
(false != false) prevented the unfocus from ever reaching the renderer.
Three changes:
- Initialize lastFocusState=true to match Ghostty's default
- In setFocus(), update lastFocusState before the surface-nil guard so
the desired state is tracked even when the C surface doesn't exist yet
- In createSurface(), sync focus state after creation so surfaces that
were logically unfocused before the C surface existed get the correct
state applied
Fixes https://github.com/manaflow-ai/cmux/issues/2080
* Sync focus state unconditionally in createSurface
Per review feedback: always call ghostty_surface_set_focus(createdSurface,
lastFocusState) instead of only syncing when !lastFocusState. This avoids
coupling to Ghostty's default focused=true and is more robust if the
upstream default ever changes.
* Keep lastFocusState in sync with AppKit responder focus calls
The becomeFirstResponder, resignFirstResponder, and ctrl-key fast paths
call ghostty_surface_set_focus directly without updating lastFocusState.
This could cause the dedup guard in setFocus() to skip a needed call, or
createSurface() to replay a stale state on surface recreation.
Add recordExternalFocusState() and call it alongside each direct C focus
call so lastFocusState stays authoritative.
* Rename lastFocusState to desiredFocusState
The variable now tracks focus intent (may be set before the C surface
exists), not just the last-applied state. Update the name and doc
comment to reflect this.

Add tty field to surface items in system.tree JSON response,
reading from existing surfaceTTYNames dictionary. Also show
tty= in the CLI text tree output for terminals that have a
registered TTY.
This enables external tools (e.g. CodeV) to cross-reference
claude process TTYs with cmux surfaces for accurate session
detection when multiple sessions share the same working directory.
Two fixes:
1. Use FileManager.temporaryDirectory for diagnostics path instead of
hardcoded /tmp/ — Process-spawned app inherits the test runner's
sandbox and can't write to /tmp/.
2. Add orderFrontRegardless() after activate() in the UI test window
creation path — on headless CI runners, activate() silently fails
and windows stay invisible, preventing terminal rendering.

Double-clicking to select text in the terminal was causing unwanted cursor
movement because the mouse position was being updated on both the first and
second clicks. This disrupted the selection gesture and caused the cursor to
jump to a different position than intended.
Fix by only updating the mouse position on the first click (clickCount == 1),
allowing the terminal's selection logic to handle multi-click gestures without
cursor interference.

When a pane split occurs, SwiftUI recreates host views and the portal
system rebinds the WKWebView to a new container. However, the bind path
never called BrowserWindowPortalRegistry.refresh(), so WebKit's internal
rendering state (_exitInWindow/_enterInWindow) was never cycled. This
left the WKWebView frozen in the original pane after a split.
Add refresh() calls after every portal bind that changes the host, in
three code paths: the main update path (shouldBindNow), onDidMoveToWindow,
and onGeometryChanged. The refresh is a no-op when no reattach is needed
(browserPortalNeedsRenderingStateReattach == false), so normal rendering
is unaffected.

Use charactersIgnoringModifiers instead of characters when redispatching
Cmd-modified key events in performKeyEquivalent. Cmd-modified keys don't
produce text characters, so event.characters returns an empty string for
Cmd+Shift combos, preventing Ghostty from encoding them as kitty protocol
sequences. charactersIgnoringModifiers returns the actual key character
(e.g. "k" for Cmd+Shift+K) while modifiers are preserved in modifierFlags.

The `shouldConsumeSuppressedEscape` function had an early return that
unconditionally consumed all repeated Escape key events (`isARepeat`),
regardless of whether the suppression window had expired. This caused
Escape presses to be swallowed in TUI apps (e.g. lazygit) running in
panels, because the repeat events never reached the active responder.
Removing the `isARepeat` guard lets repeated Escapes fall through to
the existing time-based check (0.35s window), which correctly expires
and stops consuming events after the command palette is dismissed.

Publishing changes from background threads is not allowed in macOS 26
(Tahoe). Ghostty action callbacks run on I/O threads but were modifying
AppKit view properties and posting notifications without dispatching to
the main thread.
Fixes:
- GHOSTTY_ACTION_SCROLLBAR: wrap in DispatchQueue.main.async
- GHOSTTY_ACTION_CELL_SIZE: wrap in DispatchQueue.main.async
- GHOSTTY_ACTION_COLOR_CHANGE: wrap background color updates in main async
- GHOSTTY_ACTION_CONFIG_CHANGE: wrap background color clear in main async
- Add hasLiveSurface guard in TabManager.inheritedTerminalConfigForNewWorkspace
to protect the cmuxInheritedSurfaceConfig call site missed in the initial fix
- Expand malloc_size comment to clarify it is a best-effort heuristic, not a
lifetime guarantee (per Copilot review)
