* Add typing hot path timing diagnostics
* Add stress workspace debug menu item
* Restore stress workspace preload debug path
* Reduce typing lag from sidebar re-evaluation and hitTest overhead
hitTest: gate divider/sidebar/drag routing to pointer events only,
avoiding two full view-tree walks per non-pointer event.
forceRefresh: replace per-keystroke ISO8601DateFormatter + FileHandle
I/O with dlog() in DEBUG builds.
TabItemView: replace @EnvironmentObject subscriptions with plain refs
and precomputed parameters, add Equatable conformance to skip body
re-evaluation when parent rebuilds with unchanged values. @self changed
re-evaluations dropped from 668 to 1 during rapid typing.
* Add typing-latency guardrail comments and CLAUDE.md pitfalls
Strategic comments on hitTest, TabItemView, and forceRefresh to prevent
future regressions. Adds typing-latency-sensitive paths to CLAUDE.md
pitfalls section so agents know the constraints before editing.
* Add workspace palette actions and fix release autosave typing guard
Add Move Up/Down/Top, Close Other/Above/Below, Mark Read/Unread to
Cmd+Shift+P command palette and a Workspace submenu in the menu bar.
Fix recordTypingActivity() being gated behind #if DEBUG, which prevented
release builds from honoring the typing quiet period in autosave.
* Add regression test for terminal notification click dismissal
* Dismiss terminal notifications on direct clicks
* Add regression for focused terminal notification ring
* Keep focused terminal notifications unread until click
* Verify direct notification dismiss triggers flash
* Use focus-flash path for direct notification dismiss
* Align notification dismiss flash with ring geometry
* Add workspace pages in the titlebar
* Add workspace pages UI test target entry
* Relax workspace pages UI test titlebar checks
* Use page close button in workspace pages UI test
* Stabilize workspace pages UI test interruptions
* Skip page close confirms in UI tests
* Clean up superseded workspace handoffs
* Tighten page hint UI assertions

* Fix orphaned child processes when closing workspace tabs
When closing a workspace tab via the sidebar X button, child processes
(login → zsh → claude) survived as orphans because TabManager.closeWorkspace()
only removed the workspace from the tabs array without explicitly freeing
Ghostty surfaces. It relied on ARC to cascade deallocation, but SwiftUI views
and Combine publishers held references, delaying or preventing
ghostty_surface_free() (which sends SIGHUP) from ever running.
This adds explicit teardown on the workspace close path:
- TerminalSurface.teardownSurface(): idempotent method to free the Ghostty
runtime surface eagerly, matching the existing deinit logic
- TerminalPanel.close() now calls teardownSurface() to ensure SIGHUP is sent
- Workspace.teardownAllPanels() iterates all panels and closes them
- TabManager.closeWorkspace() calls teardownAllPanels() before removing
the workspace from the tabs array
* Harden workspace teardown and ownership checks
* Address follow-up teardown review feedback

* Add markdown viewer panel with live file watching
Introduce a new PanelType.markdown that renders .md files in a dedicated
panel using MarkdownUI (SwiftUI), with live file watching via DispatchSource
so content auto-updates when the file changes on disk.
- New MarkdownPanel class with file system watcher (write/delete/rename/extend)
- New MarkdownPanelView with custom cmux theme (headings, code blocks, tables,
blockquotes, inline code, lists, horizontal rules, light/dark mode)
- Full workspace integration: SurfaceKind, creation methods, tab subscription
- Session persistence: snapshot/restore across app restarts
- V2 socket command: markdown.open (validates path, resolves workspace, splits)
- CLI command: cmux markdown open <path> with routing flags and help text
- Agent skill: skills/cmux-markdown/ with SKILL.md, openai.yaml, and references
- Cross-link from skills/cmux/SKILL.md to the new markdown skill
- SPM dependency: gonzalezreal/swift-markdown-ui 2.4.1
* Fix unreachable guard in markdown subcommand dispatch
Use looksLikePath() to distinguish subcommands from path arguments
so the guard can catch unknown subcommands and future subcommands
are parsed correctly.
* Use .isoLatin1 fallback instead of .ascii for encoding recovery
ASCII is a strict subset of UTF-8, so falling back to .ascii after
UTF-8 fails is dead code. Use .isoLatin1 which accepts all 256 byte
values and covers legacy encodings like Windows-1252.
* Mark fileWatchSource as nonisolated(unsafe) for deinit safety
deinit is not guaranteed to run on the main actor, so accessing
@MainActor-isolated storage is a data race under strict concurrency.
DispatchSource.cancel() is thread-safe, so nonisolated(unsafe) is
sufficient with a documented invariant that writes only occur on main.
* Fix file watcher reattach: retry loop with cancellation guard
- Replace one-shot 500ms retry with up to 6 attempts (3s total window)
so files that reappear after a slow atomic replace are picked up
- Add isClosed flag checked before each retry to prevent restarting
the watcher after close()/deinit
* Harden path validation in markdown.open command
Reject directories and non-absolute paths before panel creation
to prevent ambiguous behavior and generic downstream failures.
* Always reattach file watcher on delete/rename events
After an atomic save (delete old + create new), the DispatchSource still
points to the old inode. Previously we only reattached when the file was
unreadable, so successful atomic saves left the watcher on a stale inode
and live updates silently stopped. Now we always stop and reattach:
immediately if the new file is readable, via retry loop if not.
* Restore markdown panels even when file is missing at launch
MarkdownPanel already handles unavailable files gracefully (shows
'file unavailable' UI and retries via the reattach loop). Dropping
the panel on restore lost the user's layout for files that may
reappear shortly after (network drives, build artifacts, etc.).
* Harden markdown CLI parsing and startup reconnect behavior

* Add i18n infrastructure with String Catalog and Japanese translations
Introduce String Catalog (.xcstrings) for localization support:
- Localizable.xcstrings: 195 UI string entries with en and ja translations
- InfoPlist.xcstrings: Info.plist strings (microphone usage, Finder menu items)
- project.pbxproj: add xcstrings to build phase and ja to knownRegions
* Replace hardcoded UI strings with String(localized:defaultValue:)
Migrate all user-facing strings across 11 source files to use
String(localized:defaultValue:) API (macOS 13+). Each string references
a key in Localizable.xcstrings, with the English text preserved as
defaultValue for fallback.
Files modified:
- KeyboardShortcutSettings: 28 shortcut labels
- SocketControlSettings: mode names and descriptions
- TabManager: placement labels, color names, close dialogs
- BrowserPanel/BrowserPanelView: error pages, context menus, tooltips
- UpdateViewModel/UpdatePopoverView/UpdatePill: update UI states
- NotificationsPage: notification panel labels
- SurfaceSearchOverlay: search bar placeholder and tooltips
- AppDelegate: menus, dialogs, command palette items
* Fix localization gaps from review feedback
Address review comments from CodeRabbit, Greptile, and Cubic Dev AI:
- Use interpolated String(localized:) instead of concatenation for
version/progress strings in UpdateViewModel
- Localize remaining hardcoded strings in AppDelegate: window labels,
rename dialog, status menu items, unread notification count
- Localize insecure HTTP alert body in BrowserPanel
- Add 12 new entries to Localizable.xcstrings with Japanese translations
* Fix String(localized:defaultValue:) keys to use StaticString
The localized: parameter requires StaticString when defaultValue: is
used. Move string interpolation from the key to defaultValue only,
and revert maxWidthText to plain strings since they are only used for
layout width calculation.
* Localize remaining UI strings across all source files
Add String(localized:defaultValue:) to all user-facing strings in:
- cmuxApp.swift: settings screen, menus, about panel, dialogs (~180 strings)
- ContentView.swift: command palette, sidebar context menu, dialogs (~200 strings)
- Workspace.swift: rename/move/close tab dialogs, tooltips (~20 strings)
- UpdateTitlebarAccessory.swift: titlebar tooltips, notifications popover (~10 strings)
- TerminalNotificationStore.swift: notification permission dialog (4 strings)
- CmuxWebView.swift: browser context menu items (2 strings)
- AppDelegate.swift: CLI install/uninstall alerts (6 strings)
Add 418 new entries to Localizable.xcstrings with Japanese translations.
Extract sidebar context menu into separate @ViewBuilder to fix Swift
type-checker timeout in large body.
Fix xcstrings format specifiers for interpolated strings (%lld, %@).
Total: 624 localization entries covering the full UI.
* Address review feedback: fix missing localizations and terminology
- Localize javaScriptDialogTitle URL branch in BrowserPanel
- Localize cantReach error message in BrowserPanel
- Localize close other tabs dialog message in TabManager
- Localize workspace accessibility label in ContentView
- Fix unread notification singular/plural (split into two keys)
- Fix insecure connection apostrophe inconsistency (unify to U+2019)
- Rename socketControl.fullOpen.description to socketControl.allowAll.description
- Remove dead code: renameTargetNoun function
- Fix terminology inconsistencies in xcstrings:
- Unify "Developer Tools" to デベロッパツール
- Unify "Jump to Latest Unread" phrasing
- Unify "Flash Focused Panel" terminology
- Fix dialog.enableNotifications.notNow translation
* fix: address remaining PR 819 review feedback
* fix: use a single localized key for close-other-tabs
* fix: avoid inflection markup in close-other-tabs message
* Address review feedback: localize tooltip, fix subtitle concat, unify keys
- Localize menubar tooltip unread count (hardcoded English -> localized)
- Replace subtitle string concatenation anti-pattern with single localized
keys containing interpolation placeholders
- Unify workspace fallback key to workspace.displayName.fallback
- Remove unused workspace.defaultName key from xcstrings
- Add Japanese translations for new tooltip and subtitle keys
Propagate workspace remote state + heartbeat into browser panels, add heartbeat emission in remote session controller, extend docker bootstrap regression for heartbeat continuity after blank browser open, and scrub workspace/surface env vars in tagged reload launches.
* Honor Ghostty background-opacity across all cmux chrome
Parse background-opacity from Ghostty config and propagate it through
the entire chrome pipeline: bonsplit tab bar (via RRGGBBAA hex),
browser panel/omnibar, titlebar, empty panel, and window background.
Decouple glass effect from sidebar blend mode — bgGlassEnabled now
defaults to false so opacity works independently. Add
GhosttyBackgroundTheme helper for consistent color+opacity resolution
across all UI surfaces.
Fixes https://github.com/manaflow-ai/cmux/issues/263
* Titlebar and chrome opacity matches terminal background-opacity
Use CALayer-level opacity for the titlebar background instead of SwiftUI
Color alpha, matching the terminal's Metal compositing path. Account for
the double alpha stacking in the terminal area (Bonsplit container bg +
Ghostty renderer) so the titlebar visually matches.
Also fix opacity-only config changes not triggering titlebar refresh on
Cmd+Shift+, reload.
