* Fix update attempt refreshing pill without actually updating
The attemptUpdate() subscriber watched for .updateAvailable state to
auto-confirm, but showUpdateFound used setStateAfterMinimumCheckDelay
which delays the transition by up to 2 seconds. During that window,
dismissUpdateInstallation (from a background probe race) could cancel
the pending transition, reverting state to idle without ever confirming.
The subscriber then tore down on the transient idle, silently abandoning
the update.
Fix: move auto-confirm to the Sparkle driver level via an
autoInstallOnNextUpdate flag. When set, showUpdateFound immediately
calls reply(.install) bypassing the delay entirely. The subscriber
is kept as a fallback but no longer tears down on transient idle
while the flag is active.

* Revert "Fix update attempt refreshing pill without actually updating"
This reverts commit 1cd842dd924bf114b096f222851c47d2e36ad4d9.
* Fix update attempt refreshing pill without actually updating
The attemptUpdate() subscriber tore down monitoring whenever it saw
.idle after observing progress. During check startup (retry loop,
background probe race), state can transiently return to .idle before
Sparkle's interactive check begins. The subscriber interpreted this
as "check completed" and stopped monitoring, so the auto-confirm
for .updateAvailable never fired.
Fix: add !state.isIdle to the teardown guard so monitoring only
stops on terminal failures (.notFound, .error), not transient idle.
Closes https://github.com/manaflow-ai/cmux/issues/2166

* New window inherits size from current window
When creating a new window via Cmd+Shift+N, use the key window's
frame dimensions instead of the hardcoded 460x360 default. The new
window cascades from the existing window's position so it doesn't
stack directly on top.
* Use Ghostty's cascade algorithm for new window positioning
Match upstream Ghostty's window cascade logic: maintain a
lastCascadePoint that tracks where the next window should appear.
First window seeds the point from its own top-left corner, subsequent
windows advance the cascade point via NSWindow.cascadeTopLeft(from:).
On window close, reset the cascade point to the closing window's
position so the next window appears nearby.
New windows still inherit the key window's size so Cmd+Shift+N
creates a window matching the previous one's dimensions.
* Fix frame-to-contentRect conversion and use preferred window resolver
Convert existingFrame to a content rect via
NSWindow.contentRect(forFrameRect:styleMask:) so the new window
matches the source window's actual size instead of growing by
titlebar insets on each Cmd+Shift+N.
Use preferredMainWindowContextForWorkspaceCreation to resolve the
source window, consistent with showOpenFolderPanel and other
callers.

* Handle Cmd+O in handleCustomShortcut to prevent Documents folder open
Cmd+O for "Open Folder" was only handled in SwiftUI menu, which can
fail due to focus bugs when terminal is focused. This caused AppKit's
default NSDocumentController to open the Documents folder instead.
Now Cmd+O is intercepted in handleCustomShortcut like other shortcuts.

* Add set-color/clear-color workspace actions for tab color via CLI
Expose the existing tab color functionality through the workspace-action
CLI command, enabling programmatic tab color setting without the GUI
context menu.
Supports both named colors (Red, Blue, Amber, etc.) and hex values
(#RRGGBB). Named colors resolve against the built-in palette via
case-insensitive matching.
Usage:
cmux workspace-action --action set-color --color blue
cmux workspace-action --action set-color --color "#C0392B"
cmux workspace-action set-color Amber
cmux workspace-action clear-color
* Return explicit null color in clear_color JSON response
Restore "color": null in the clear_color response payload so JSON
consumers can distinguish "color was cleared" from "no color field".

The socket API's send-key command only supported enter, escape, tab,
backspace, and ctrl+letter. Arrow keys and shift+tab had to be sent
as raw escape sequences via send_text, but 0x1B is filtered out by
socketTextChunks and converted to a standalone Escape key event,
breaking multi-byte sequences like \x1b[A (ArrowUp).
This commit extends sendNamedKey to handle:
- Arrow keys: up/down/left/right (with arrow_up/arrowup aliases)
- shift+tab / shift-tab / backtab
- home, end
- delete / del / forward_delete
- pageup / page_up
- pagedown / page_down
These map directly to the existing sendKeyEvent infrastructure using
the appropriate kVK_* keycodes and modifier flags.

* Pre-launch app for browser UI test on headless CI runners

* 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.

* 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.

Korean IME commits a syllable and executes on a single Enter, but

* 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

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

* 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.

* 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.
