* Fix stale Claude status in sidebar by adding missing hooks and OSC suppression
The Claude Code integration only used 3 hooks (SessionStart, Stop, Notification),
leaving gaps that caused stale sidebar status. Now uses 6 hooks:
- SessionEnd: clears status when Claude exits (covers Ctrl+C where Stop doesn't fire)
- UserPromptSubmit: clears "Needs input" and sets "Running" on new prompt
- PreToolUse (async): clears "Needs input" when Claude resumes after permission grant
Also:
- Suppress OSC 9/99 desktop notifications for workspaces with active Claude hook
sessions to prevent duplicates from the raw OSC path
- Store Claude process PID in status entries for stale-session detection
- Add 30-second sweep timer that checks agent PIDs and clears stale entries
(safety net for SIGKILL/crash where no hook fires)
- Update wrapper test expectations for the new hook set
Fixes https://github.com/manaflow-ai/cmux/issues/1301
* Don't show "Running" status on Claude launch, only when actually working
SessionStart now registers the PID for tracking and OSC suppression via
set_agent_pid without setting a visible status entry. "Running" only
appears when the user submits a prompt (UserPromptSubmit) or Claude
starts using tools (PreToolUse).
Added set_agent_pid / clear_agent_pid socket commands to decouple PID
tracking from visible status entries. OSC suppression checks agentPIDs
instead of statusEntries so it works during the initial idle period.
* Don't restore status entries across app restarts
Status entries are ephemeral runtime state tied to running processes
(e.g. claude_code "Running"). Restoring them after restart shows stale
status for processes that no longer exist.
* Address PR review comments and remove debug logging
- session-end: only clear status/PID/notifications when Stop didn't fire first
- PID sweep: check errno == ESRCH instead of treating all kill(pid,0) failures as dead
- Validate CMUX_CLAUDE_PID > 0
- Propagate tracked PID in pre-tool-use setClaudeStatus
- OSC suppression: use tabManagerFor(tabId:) for multi-window support
- clearAgentPID: resolve tab UUID before async dispatch
- restoreSessionSnapshot: also clear agentPIDs alongside statusEntries
- Fix AskUserQuestion surfaceId overwrite (wrong workspace notification)
- Fix notification text matching for "Claude Code needs your attention"
- AskUserQuestion: render option labels as bracketed inline text
- Remove artificial text truncation limits
- Remove temporary JSONL debug logging from all handlers
* Use resolveTabIdForSidebarMutation in clearAgentPID
Previously, Cmd+W on the last surface kept the workspace alive with a
replacement shell, unless the user toggled a hidden setting. This was
confusing—users expect Cmd+W to close the window when there's nothing
left.
Now Cmd+W (and the tab-strip X button) always close the workspace when
they close its last surface, and close the window when that was the last
workspace. Internal/programmatic closes (e.g. process exit, panel moves)
still spawn a replacement shell so the workspace stays alive.
Key changes:
- Track explicit user close gestures via markExplicitClose / onTabCloseRequest
- Remove the LastSurfaceCloseShortcutSettings toggle (now always-on)
- Use window.performClose for last-workspace window close
- Update tests to match the new behavior

Snapshot TabManager's published state (tabs, selectedTabId) at the start
of workspace creation so mutations don't bounce through Combine-backed
accessors mid-creation. Prevents crashes when adding a workspace via
Cmd+N, the new-workspace button, or any other creation path that
triggers re-entrant publishes.

* 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 cmux welcome command with ASCII logo and shortcuts
Adds `cmux welcome` CLI command that prints a blue-to-purple gradient
chevron logo, version info, and key shortcuts. Auto-runs once on first
workspace creation via UserDefaults. Adds "Welcome" to the ? help menu
in the sidebar footer, which opens a new workspace running the command.
* Polish welcome, feedback, and shortcuts flows
* 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 sidebar help menu
* Fix help menu test wiring
* Fix help menu accessibility
* Use native popup for help menu
* Use icon button for sidebar help
* Add feedback composer and feedback API
* Allow preview builds without feedback env
* Tighten feedback upload limits
* Adjust sidebar footer padding
* Tighten sidebar footer spacing
* Add link affordances to help menu
* Polish sidebar feedback composer
* Move feedback icon to trailing edge
* Normalize help menu trailing icon sizes
* Enlarge help menu trailing icons
* Reduce help menu link icon size
* Shrink help menu link arrow
* Reduce help menu link arrow again
* Fix feedback message editor focus
* Add send feedback keyboard shortcut
* Polish feedback launch and delivery
* 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
