Closes #3614.

Summary

  • Adds a direct Claude hook regression for SessionStart(source=clear) followed by a stale Stop from the previous session.
  • Implements the lifecycle fix in the next commit: the hook store tracks the active Claude session per workspace, promotes /clear SessionStart to Running, and gates visible Stop/Notification/SessionEnd mutations on the active session.

Architecture choice

I chose the robust active-session model over the narrow source=clear patch. The narrow patch would restore Running at the clear boundary, but a late pre-clear Stop or SessionEnd could still overwrite the fresh session. Making the hook store the owner of the current workspace session eliminates that class of stale lifecycle clobbers.

References

  • Claude Code hooks docs: SessionStart includes source values such as startup, resume, and clear.

Testing

  • Not run locally per repository policy.
  • Pushed the test-only commit first so PR CI can prove the regression fails before the fix commit.

Note

Medium Risk
Touches Claude hook session lifecycle and auth token mutation handling; incorrect gating or mutation generation bugs could cause missed status updates or sign-in/out inconsistencies.

Overview
Prevents Claude sidebar/status from being clobbered by late hook events after /clear by tracking an active Claude session (and optional turn) per workspace and gating visible mutations (stop, notification, pre-tool-use, session-end, PID/status writes) to the current session; /clear SessionStart now clears notifications and immediately sets Running.

Refactors Codex hook install/uninstall to toggle codex_hooks in config.toml (with legacy marker cleanup), adds a new regression test for the /clear lifecycle, and wires it into CircleCI/GitHub Actions; CI Zig install is stabilized via Homebrew no-update flags.

Also tightens auth and UI plumbing: auth sign-in/out becomes mutation-aware (cancel/ignore stale callbacks, conditional token clears, redacted logging), window geometry persistence is moved to app-managed defaults as a fallback, update state transitions go through UpdateViewModel.applyDriverState, and several input/IME and first-mouse/key forwarding paths are simplified/adjusted.

Summary by cubic

Keeps Claude Running after a /clear by tracking the active Claude session (+turn) per workspace and ignoring stale events. Adds a direct regression test for #3614 and tightens auth, updates, IME, the claude wrapper, browser key forwarding, and CI.

  • Bug Fixes

    • Claude lifecycle: promote SessionStart(source=clear) to Running; track active session/turn per workspace; ignore stale stop, prompt-submit, notification, pre-tool-use, and session-end; clear active turnId after stop; guard session-end against the consumed workspace; normalize workspace keys; keep panel‑scoped PID/status updates; allow new sessions to replace stopped owners while keeping /clear non‑replaceable.
    • Auth: cancel in‑flight browser auth on sign‑out; discard late callbacks; await token state before comparisons; atomically clear tokens only if still current; redact tokens/emails/JWTs/opaque state in logs.
    • Updates: route driver changes through UpdateViewModel.applyDriverState, preserve detected update metadata for a stable pill, and dismiss stale Sparkle replies.
    • IME: clear stale marked text and stop ghost key forwarding at composition end; fixes Traditional Chinese numpad and related cases.
    • Browser keys: preserve Return reentry dispatch while keeping forwarding narrow and predictable.
    • claude wrapper: bypass hook/session injection for built‑in subcommands, --help/--version, and command‑like invocations discovered from real CLI help.
  • Dependencies

    • CLI install/uninstall toggles codex_hooks = true in config.toml, cleans legacy hooks config, and removes an empty [features] table if present; tests cover legacy marker and empty‑table cleanup.
    • CI: hardened Zig installation (retries; suppress Homebrew churn/env hints) and added the clear‑running regression to CircleCI, GitHub Actions, and perf activation.

Written for commit 035e374. Summary will update on new commits.

Summary by CodeRabbit

  • New Features

    • Persistent tracking of active Claude sessions for more accurate visible session state.
    • App-managed primary-window geometry persistence for safer window restore.
  • Bug Fixes

    • Prevents late/stale Claude events from overwriting running/clear workspace status.
    • Auth flows (sign-in/sign-out/refresh) made mutation-aware to avoid lost or stale tokens.
    • Claude wrapper now bypasses hook injection for help/command-like invocations.
  • Tests

    • Expanded regression coverage (Claude hooks, wrapper bypasses, auth, codex hooks) plus a new Python regression.
  • CI / Chores

    • CI runs the new regression and sets Homebrew no-update/cleanup/env flags during install.

Review Change Stack

The regression exercises the Claude hook handler directly with a SessionStart payload whose source is clear, then sends a late Stop for the previous session. The current handler does not promote the clear boundary to Running or reject stale Stop mutations, so this test is expected to fail before the lifecycle fix.

Constraint: Tests must exercise the hook handler directly rather than driving the full app.

Confidence: high

Scope-risk: narrow

Directive: Keep this regression on the direct CLI hook path; do not replace it with source-text assertions.

Tested: Not run locally per repository policy.

Not-tested: CI red/green proof pending on GitHub Actions.
Add hook-level regression coverage for Claude Code /clear. The tests drive the bundled CLI against a mock cmux socket so CI proves SessionStart(source=clear) must set the visible Running status and a prior session Stop must not clobber that fresh lifecycle.

Constraint: Local tests are intentionally not run; CI owns test execution for this task.
Confidence: high
Scope-risk: narrow
Tested: Not run locally per instruction
Not-tested: Full app UI repro under CI

Claude /clear starts a fresh hook lifecycle but the sidebar status key is shared at the workspace level. Persist the active Claude session per workspace, promote clear SessionStart to a visible Running state, and ignore teardown or notification mutations from sessions that are no longer current.

Rejected: Only set Running on clear SessionStart | late Stop from the previous lifecycle could still clobber the new status.

Claude /clear arrives as a SessionStart source=clear event, but the hook store only remembered routing data.

Greptile Summary

This PR fixes the Claude status staying "Running" after /clear by introducing an active-session-per-workspace model in ClaudeHookSessionStore: each workspace tracks one canonical ClaudeHookActiveSessionRecord, and all visible-state mutations (stop, prompt-submit, notification, pre-tool-use, session-end) are gated on that record via isCurrent/canReplaceActiveSession. A SessionStart(source=clear) immediately promotes the new session to active and writes "Running", preventing any late pre-clear Stop from overwriting it.

  • Claude lifecycle fix (CLI/cmux.swift): new activeSessionsByWorkspace dictionary, isCurrent guard on all visible mutations, allowsNewSessionReplacement flag on stopped sessions so the next prompt-submit can take over; a dedicated Python regression covers the stale-Stop and multi-turn paths.
  • Auth hardening (Sources/Auth/AuthManager.swift): generation-based mutation tracking, attempt-ID-scoped browser sessions, snapshot-safe clearTokensIfCurrent in all token stores, and auth log redaction flowing to unified Logger in production.
  • Window geometry (Sources/AppDelegate.swift): replaces AppKit frameAutosaveName with explicit UserDefaults-backed persistence; fixes a latent bug where the v2 geometry key was inadvertently included in the legacy-cleanup list.

Confidence Score: 4/5

Safe to merge; the core lifecycle fix and auth hardening are well-reasoned and all previously flagged critical bugs have been resolved.

All previously flagged bugs are addressed in this revision. The remaining findings are a dead loginPollTask field that is always nil and a hardcoded authLogger subsystem string — neither causes incorrect runtime behaviour.

CLI/cmux.swift has grown to 21,873 lines and warrants extraction of the hook-store and TOML helpers. Sources/Auth/AuthManager.swift has the dead loginPollTask variable that should be cleaned up.

Important Files Changed

Filename Overview
CLI/cmux.swift Core lifecycle fix: adds ClaudeHookActiveSessionRecord, active-session-per-workspace tracking, isCurrent/canReplaceActiveSession guards on all visible mutations. Logic is correct but file has grown to 21,873 lines.
Sources/Auth/AuthManager.swift Auth races fixed via generation tracking, attempt IDs, and snapshot-safe clearTokensIfCurrent. Logging restored to unified Logger with redaction. loginPollTask is dead code and authLogger subsystem is hardcoded.
Sources/AppDelegate.swift Replaces AppKit frameAutosaveName machinery with explicit UserDefaults-backed geometry persistence. Correctly removes the v2 key from the legacy-cleanup list.
Sources/Update/UpdateViewModel.swift Introduces applyDriverState to unify update-state transitions; pill metadata stays stable across state changes.
tests/test_claude_hook_clear_running_status.py New regression covering /clear stale-Stop and multi-turn continuations.
CLI/CMUXCLI+CodexConfigToml.swift Deleted; logic migrated into cmux.swift with anchored TOML-line helpers.

A visible hook mutation can only be rejected as stale after the active session boundary is known. Keeping a completed turn id active after Stop made the next prompt in the same Claude session look stale before it could promote its own turn.

The Stop path now refreshes the active session with no turn id once the completed turn has been accepted, preserving stale-session protection across /clear while allowing normal multi-turn prompts to re-enter Running. The regression now exercises that two-turn path before the clear boundary.

Constraint: Do not run local tests; CI owns verification for this branch.
Rejected: Ignore turn id in all current-session checks | would weaken stale turn filtering for late Stop and Notification events.
Confidence: high
Scope-risk: narrow
Directive: Do not persist a completed turn id past Stop without proving the next prompt-submit can promote a new turn.
Tested: git diff --check
Not-tested: Local unit/regression tests per project policy
The origin branch already carried the stronger active-session and turn-aware hook model for issue 3614. This merge keeps that state model while retaining the local direct hook regression coverage added before the branch moved.

Constraint: Preserve origin/issue-3614-claude-clear-running-status without force-pushing or rewriting another writer's work
Constraint: Local tests are intentionally not run; CI owns verification for this task
Rejected: Force-push local two-commit history | would discard the already-pushed authoritative fix and violate shared-branch safety
Confidence: medium
Scope-risk: narrow
Tested: git diff --check
Not-tested: Local test execution, per task instruction
The shared branch gained a follow-up that prevents accepted Stop events from freezing the active turn id and making the next prompt in the same Claude session look stale. Keep that behavior while preserving the non-force-push integration history.

Constraint: Preserve origin history and push only to manaflow-ai/cmux
Constraint: No local tests per task policy
Rejected: Force-push over origin | branch moved with a valid follow-up lifecycle fix
Confidence: medium
Scope-risk: narrow
Tested: git diff --check before merge; merge strategy completed without manual code edits if clean
Not-tested: Local test execution
Comment thread CLI/cmux.swift
The branch integration accidentally kept two isClaudeClearSessionStart definitions in CLI/cmux.swift. The duplicate version referenced a non-existent parsedInput.source property, so Swift would reject the file before CI could exercise the hook lifecycle tests.

Keep the existing implementation that reads source from the parsed hook object and delete only the duplicate helper.

Constraint: Fix review-reported compile blocker without changing lifecycle behavior.
Rejected: Add source to ClaudeHookParsedInput | unnecessary for this compile fix and broader than the failing duplicate.
Confidence: high
Scope-risk: narrow
Directive: Keep exactly one Claude clear source helper unless the parsed input model is intentionally extended.
Tested: git diff --check; rg confirms a single isClaudeClearSessionStart definition and no parsedInput.source reference.
Not-tested: Local tests per project policy
The active-session merge left behind the old source-property helper alongside the newer compact-payload helper. Removing the duplicate keeps source=clear detection on the JSON payload and avoids both the redeclaration and missing-property errors.

Constraint: Do not run local tests; CI owns verification for this branch
Rejected: Reintroduce ClaudeHookParsedInput.source | duplicates state already retained in the compact hook payload
Confidence: high
Scope-risk: narrow
Tested: git diff --check; rg verified a single isClaudeClearSessionStart definition and no parsedInput.source references
Not-tested: Local compile/test execution per task policy
Origin advanced with the same compile fix for the duplicate Claude clear helper. Merge it instead of force-pushing the local equivalent commit so the shared PR branch remains append-only.

Constraint: Preserve origin branch history and push only to manaflow-ai/cmux
Rejected: Force-push local equivalent commit | unnecessary and would rewrite the shared branch
Confidence: high
Scope-risk: narrow
Tested: git diff --check before local equivalent commit; origin commit records the same static checks
Not-tested: Local tests per project policy
Comment thread CLI/cmux.swift
The active-session map is keyed by normalized workspace id, so cleanup after consuming a session must use the same normalized key. Otherwise a record containing incidental whitespace could leave a stale active-session entry behind.

Constraint: Address reviewer-reported lifecycle cleanup edge case without changing visible hook behavior.
Rejected: Store raw workspace ids as active map keys | inconsistent with existing upsert normalization and lookup guards.
Confidence: high
Scope-risk: narrow
Directive: Any activeSessionsByWorkspace lookup should use the normalized workspace key, matching insertion.
Tested: git diff --check
Not-tested: Local tests per project policy
CircleCI and the activation workflow both depend on ziglang.org tarballs during remote macOS setup. A transient 500 from that host failed the debug build before any project code compiled, so the install path now retries downloads and avoids unnecessary Homebrew update/cleanup churn on CircleCI.

Constraint: CI must be made green remotely without running local tests or local xcodebuild.

Rejected: Push an empty commit to rerun CI | would leave the same upstream download flake unchanged.

Confidence: high

Scope-risk: narrow

Directive: Keep Zig installer retries in remote CI setup paths; failures here happen before project build logic runs.

Tested: git diff --check

Not-tested: Local tests and local builds not run per repository/user policy.
Greptile identified that stale SessionEnd exercises a different clear-state path than stale Stop. The existing active-session guard already blocks the mutation, so the regression now drives that hook directly and asserts the active /clear session keeps its status, PID, and notifications intact.

Constraint: Do not run local tests; CI is the verification source for this branch.

Rejected: Add another Swift integration test | the existing Python hook harness already executes the CLI handler through the socket path used by CI.

Confidence: high

Scope-risk: narrow

Tested: Not run locally per repo policy.

Not-tested: Local test execution.
The activation workflow was cancelled before build because repeated ziglang.org transfers crawled for the full job timeout. Prefer Homebrew's pinned zig@0.15 bottle on macOS runners, then keep the direct tarball path as a bounded fallback with connection, total-time, and minimum-speed limits.

Constraint: The failed check never reached project build or tests; the only failing surface was CI tool bootstrap.

Rejected: Increase the job timeout | it would hide the bootstrap failure and delay feedback.

Confidence: medium

Scope-risk: narrow

Directive: Keep activation workflow tool bootstrap bounded so performance CI reaches the benchmark or fails quickly.

Tested: git diff --check

Not-tested: Local workflow execution, per repository and user instruction.
Greptile noted that session-end computed the current-session guard from the fallback workspace while clearing the consumed session's workspace. Move the guard next to the mutation target so stale cleanup and visible cleanup always evaluate the same workspace identity.

Constraint: This is follow-up review hardening on the existing active-session model.

Rejected: Collapse activeSessionsByWorkspace into sessions in this PR | per-workspace current-session lookup is the intended lifecycle boundary for stale event gating.

Confidence: high

Scope-risk: narrow

Directive: SessionEnd visible cleanup must be gated against the workspace being cleared, not an earlier fallback lookup.

Tested: git diff --check

Not-tested: Local test execution, per repository and user instruction.
A late SessionEnd can be resolved through fallback surface lookup, so the workspace used to find a record is not always the workspace whose visible state would be cleared. Move the staleness check after consume() and evaluate it against the consumed session's workspace, where the clear_status and notification cleanup actually run.

Constraint: Hook events are delivered by short-lived CLI processes and must tolerate stale or partial Claude payloads

Rejected: Keep the pre-consume fallback workspace guard | it can validate one workspace while clearing another

Confidence: high

Scope-risk: narrow

Tested: Added Swift integration regression for stale SessionEnd fallback cleanup

Not-tested: Local tests not run per repository policy

Extract the persisted-window-geometry codec/resolver out of AppDelegate.

The new encode/decode, remap, clamp, and display-resolution logic is standalone enough to live in a dedicated helper instead of growing a 14k-line lifecycle file further.

As per coding guidelines Sources/**/*.swift: "Flag features implemented directly in the app target/module root Sources/ path when their core logic is independent of cmux app lifecycle and can compile/test without AppKit, SwiftUI view state, Ghostty globals, or process-wide singletons."

457-496: 🧹 Nitpick | 🔵 Trivial | 💤 Low value

Non-sentinel errors from refreshSession leave lastKnownAccessToken and persisted tokens populated.

The catch only matches AuthManagerError.invalidCallback where !isCurrentAuthMutation(...). Any other throw from refreshSession (e.g., transient network failure in client.currentUser() / client.listTeams()) propagates out of handleCallbackURL after tokenStore.seed(...) succeeded and lastKnownAccessToken = payload.accessToken was assigned, but before isAuthenticated/didCompleteBrowserSignIn are updated. This isn't externally observable because getAccessToken() is now gated on isAuthenticated, and restoreStoredSessionIfNeeded will recover on next launch — but the partial in-memory state (cached access token without an authenticated session and without didCompleteBrowserSignIn) is a minor surprise. Consider clearing lastKnownAccessToken (or routing through clearSessionState) on the non-sentinel throw path so the in-memory cache stays consistent with isAuthenticated.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Fallback to persisted geometry when the primary snapshot frame is unusable.

If primaryWindowSnapshot exists but its frame resolves to nil/invalid, applySessionWindowSnapshot(...) becomes a no-op and this branch never tries the new persisted-geometry fallback. Startup then falls back to the default rect instead of the last saved window placement.

⚠️ Potential issue | 🟠 Major | ⚡ Quick win

Keep browser reentry out of the original NSWindow.performKeyEquivalent path.

Both reentry guards call cmux_performKeyEquivalent(with:), which is the original AppKit implementation after swizzling. That reintroduces the SwiftUI/AppKit window-level path for the exact WKWebView-focused reentry case this file is trying to bypass, so Return/arrow handling can still get swallowed on browser surfaces.

             }

Based on learnings, ensure that NSWindow.cmux_performKeyEquivalent forwards to firstResponderWebView.performKeyEquivalent and returns its Bool unconditionally to prevent re-entry into SwiftUI’s performKeyEquivalent path when WKWebView has focus.

Relax the [features] insertion assertion to avoid false negatives.

Line 574 currently requires codex_hooks = true to be immediately after [features]. That’s stricter than the test intent and can fail valid implementations that preserve existing key order.

next section header (a line starting with "[") or the end and assert that one of
those lines equals "codex_hooks = true" (i.e., check membership in that feature
block) so existing keys/order are allowed while still ensuring the feature was
inserted.

* Fix #3807: bring notification CLI to panel parity (#3811)

* Prove notification CLI parity is missing

Add behavior-level coverage for the missing notification socket and CLI actions before implementing them. The tests drive V2 notification action methods, CLI subcommands, extended list fields, and the UI open-notification flow so CI can show the pre-fix gap.

Constraint: Regression tests must be committed before the implementation for issue #3807

Constraint: Local Swift tests are not run in this repo; verification is through CI

Confidence: high

Scope-risk: narrow

Tested: git diff --check

Not-tested: Swift/XCUITest execution; intentionally deferred to CI

* Make notification actions scriptable from the CLI

The notifications panel already owned the behavior for dismissing, marking read, opening, and jumping to unread rows. This wires the socket and CLI to those existing store/AppDelegate paths, extends list output with panel metadata, and documents the new command surface without introducing a second notification action model.

Constraint: Existing Notifications page behavior must remain the source of truth

Constraint: Direct xcodebuild and local Swift/XCUITest runs are forbidden in this workspace

Rejected: Duplicate CLI-side focus or read-state logic | would diverge from AppDelegate.openNotification and TerminalNotificationStore semantics

Confidence: medium

Scope-risk: moderate

Tested: git diff --check

Tested: jq empty Resources/Localizable.xcstrings

Tested: python3 -m json.tool Resources/Localizable.xcstrings

Not-tested: Swift unit/UI execution; deferred to CI per repo policy

* Make notification CI compile under strict concurrency

The notification parity implementation introduced a shared formatter on a main-actor type and a test helper that crossed actor boundaries through escaping closures. This keeps the socket behavior unchanged while making date formatting local to the main-actor call path and keeping the XCTest socket request helper from capturing actor-isolated state in the background request closure.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace

Rejected: Run xcodebuild locally to confirm | user explicitly warned direct xcodebuild can deadlock the machine

Confidence: medium

Scope-risk: narrow

Tested: git diff --check

Tested: jq empty Resources/Localizable.xcstrings

Not-tested: Swift compilation and XCTest execution; deferred to CI

* Make notification parity actions atomic and exact

Review feedback exposed two behavior risks in the notification parity path: bulk dismissal was implemented as client-side list-and-loop work, and jump-to-unread could report one unread notification while opening a later valid one. The server now owns already-read dismissal as a single V2 action, the jump helper returns the notification it actually opened, and event/list parsing details match those server semantics.

Constraint: Notification action logic must reuse the existing store and AppDelegate paths

Rejected: Split TerminalController into new controllers in this PR | broad refactor is unrelated to issue #3807 and would obscure the parity fix

Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace instructions

* Expose app test symbols to CLI notification coverage

The integration regression exercises real app-backed notification state through the CLI harness, so the test target must import the built app module the same way the socket action tests do.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace
Rejected: Verify with xcodebuild locally | user explicitly forbids direct xcodebuild
Confidence: high
Scope-risk: narrow

Not-tested: Swift compilation and XCTest execution; deferred to CI

* Make notification list and dismiss payloads stable

Review caught two small contract hazards in the new notification RPC surface: the dismiss result used mixed JSON types, and a pipe in the appended tab title could shift the legacy list parser. The server now reports dismissals as counts consistently and escapes only the new trailing list field, with the CLI decoding it after structural parsing.

Constraint: The V1 list response remains pipe-delimited for backward compatibility, so only newly appended trailing fields can be encoded without changing old parser behavior
Rejected: Replace list_notifications with JSON-only output | existing V1 parsers depend on the line format
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace policy

* Return async notification socket responses from tests

CircleCI caught a compile-only issue in the async V2 test helper: the continuation result was awaited but not returned from the method that promises a response dictionary. Returning the continuation value restores the helper contract without changing the exercised socket behavior.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace
Rejected: Verify with local xcodebuild | user explicitly forbids direct xcodebuild
Confidence: high

Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI

* Avoid blocking notification CLI integration sockets

The integration regression has to create AppKit-backed notification state on the main actor, but running the CLI subprocess synchronously there can block the socket handler's main-actor store mutations. The test now awaits subprocess work on a background queue and verifies read state through the same CLI list path.

Constraint: Socket notification handlers intentionally hop to the main actor for store and AppDelegate work
Rejected: Run the CLI synchronously from the main actor | it can deadlock the in-process socket server during tests
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace policy

* Harden notification CLI response contracts

The notification parity path now distinguishes new list-notification trailer fields from old pipe-heavy bodies, rejects surface-only mark-read selectors, and returns post-open read state by marking through the shared store path after a successful focus action.

Constraint: list_notifications remains a legacy pipe-delimited protocol, so the new trailer needs its own discriminator while older body parsing keeps joining payload[6...]
Rejected: Add a third list_notifications sentinel field | the issue asked for exactly the two appended fields
Rejected: Rely on AppDelegate delayed mark-read for socket JSON | CLI callers need the open response and subsequent list output to reflect the explicit action
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace policy

* Make CLI integration helper capture explicit self

CircleCI's Swift compile step requires explicit self when the background subprocess closure calls the test helper method. This keeps the deadlock fix intact while satisfying Swift capture rules.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace
Rejected: Verify with local xcodebuild | user explicitly forbids direct xcodebuild
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI

* Make CLI presentation flags order-independent

Users naturally put presentation flags next to the command they are inspecting. Normalize --json and --id-format after command selection so docs examples such as cmux list-notifications --json produce JSON while still preserving literal flag-looking values for command options.

Constraint: Do not run reload.sh before CI is green; never run bare xcodebuild.

Rejected: Documentation-only correction | leaves copy-pasted command behavior surprising.

Rejected: Notification-only --json handling | repeats the same parser split for future JSON-capable commands.

Confidence: medium

Scope-risk: moderate

Directive: Keep presentation flag parsing centralized; update commandOptionsWithValues when adding value-taking command options.

Tested: git diff --check

Not-tested: Local XCTest/build per repo policy; CI will verify.

* Prevent display-link crash from terminal portal layout reentry (#3885)

* Pin portal sync deferral during SwiftUI host callbacks

The silent-exit crash path points at SwiftUI/AppKit layout recursion reaching a CATransaction display-link flush. This test locks the intended invariant: geometry callbacks originating from the SwiftUI NSViewRepresentable host must defer portal reconciliation instead of forcing immediate AppKit layout, even while an interactive resize is active.

Constraint: Local tests are intentionally not run in this repository; CI owns regression proof.\nRejected: Assert on source text or unified-log contents | timing-dependent and not executable through the policy seam.\nConfidence: medium\nScope-risk: narrow\nDirective: Keep immediate portal flushing owned by external AppKit resize observers, not SwiftUI host callbacks.\nTested: Not run locally per repository policy and user instruction.\nNot-tested: Full multi-session crash reproduction is timing-dependent and not deterministic.

* Prevent portal layout reentry from terminal host callbacks

The terminal NSViewRepresentable host was allowed to bind into the window portal and synchronously flush AppKit layout from update/layout callbacks. That made SwiftUI's own host layout and the external terminal portal both believe they could drive geometry in the same render turn, matching the NSHostingView reentrant-layout warnings reported before the CATransaction display-link abort.\n\nThe portal now treats SwiftUI host callbacks as state capture only: they register the binding and schedule the portal owner to reconcile geometry after the current render turn. Immediate geometry flushing remains available to the portal's external AppKit resize observers, which are outside SwiftUI body/layout evaluation. The launch path also records clean exits and posts a one-time TerminalNotificationStore breadcrumb when a newer ghostty Breakpad envelope is found after an unclean exit.

Constraint: Local tests and app builds are not run before CI for this branch; verification is delegated to CI, then the required tagged reload.\nRejected: Wrap the CATransaction/display-link exception in @try/@catch | it would hide AppKit's abort symptom without removing the reentrant layout owner split.\nRejected: Keep immediate sync during interactive SwiftUI host callbacks | still allows layoutSubtreeIfNeeded inside the representable layout/update path.\nConfidence: medium\nScope-risk: moderate\nDirective: SwiftUI/AppKit host callbacks must not force terminal portal layout synchronously; add external observer paths for any future immediate resize flushing.\nTested: git diff --check; jq empty Resources/Localizable.xcstrings\nNot-tested: Local XCTest/build/repro per repository and user instructions; 75-minute multi-session crash reproduction is not deterministic.

* Record clean-exit breadcrumb after teardown

The crash breadcrumb should compare Breakpad envelopes against the last successfully completed termination path. Recording the timestamp after teardown avoids marking an exit clean before session persistence, process cleanup, and notification cleanup have finished.

Constraint: This is a follow-up correctness tweak before CI settled.\nRejected: Keep the timestamp at the start of applicationWillTerminate | a crash during termination cleanup could suppress the next-launch breadcrumb.\nConfidence: high\nScope-risk: narrow\nDirective: Only update the clean-exit timestamp after teardown work that must complete for a clean quit.\nTested: git diff --check; jq empty Resources/Localizable.xcstrings\nNot-tested: Local tests/builds per repository and user instructions.

* Defer first portal install from SwiftUI callbacks

A deferred SwiftUI host bind could still create the WindowTerminalPortal for the first time, and the initializer previously installed the host with an immediate layout flush. Threading the same deferral flag through portal creation keeps the invariant complete: representable update/layout callbacks never synchronously flush terminal portal layout, even on first bind.

Constraint: Must preserve immediate install behavior for non-SwiftUI external portal callers
Rejected: Assume portals already exist before host callbacks | first terminal bind in a new window can create one
Confidence: high
Scope-risk: narrow
Directive: Any future portal creation path from SwiftUI callbacks must carry deferred synchronization through initialization
Tested: git diff --check; jq empty Resources/Localizable.xcstrings
Not-tested: Local tests/builds per repository and user instructions

* Move crash breadcrumb work out of launch hot path

The crash breadcrumb scanner is pure Foundation logic, so it now lives in its own source file and performs the crash-directory scan from a detached utility task. App launch only schedules the check once, then posts the existing localized notification after the background scan returns to the main actor. The terminal host geometry policy is also simplified to make the always-deferred invariant explicit at the call site.

Constraint: Local build/tests are intentionally skipped until CI completes per issue instructions
Rejected: Keep synchronous directory enumeration in AppDelegate.configure | startup should not block on crash artifact I/O
Rejected: Preserve the dead immediate portal sync branch | host callbacks are never allowed to force layout synchronously
Confidence: high
Scope-risk: narrow
Directive: Do not reintroduce synchronous crash-directory scans or immediate portal layout flushes from SwiftUI host callbacks
Tested: git diff --check; jq empty Resources/Localizable.xcstrings; plutil -lint GhosttyTabs.xcodeproj/project.pbxproj

* Keep Claude Running after clear (#3631)

* Prove Claude clear hook loses running status

The regression exercises the Claude hook handler directly with a SessionStart payload whose source is clear, then sends a late Stop for the previous session. The current handler does not promote the clear boundary to Running or reject stale Stop mutations, so this test is expected to fail before the lifecycle fix.

Constraint: Tests must exercise the hook handler directly rather than driving the full app.

Confidence: high

Scope-risk: narrow

Directive: Keep this regression on the direct CLI hook path; do not replace it with source-text assertions.

Tested: Not run locally per repository policy.

Not-tested: CI red/green proof pending on GitHub Actions.

* Prove Claude clear should own running status

Add hook-level regression coverage for Claude Code /clear. The tests drive the bundled CLI against a mock cmux socket so CI proves SessionStart(source=clear) must set the visible Running status and a prior session Stop must not clobber that fresh lifecycle.

Constraint: Local tests are intentionally not run; CI owns test execution for this task.
Confidence: high
Scope-risk: narrow
Tested: Not run locally per instruction
Not-tested: Full app UI repro under CI

* Ignore stale Claude hook events after clear

Claude /clear starts a fresh hook lifecycle but the sidebar status key is shared at the workspace level. Persist the active Claude session per workspace, promote clear SessionStart to a visible Running state, and ignore teardown or notification mutations from sessions that are no longer current.

Constraint: Claude Code emits /clear as SessionStart(source=clear).
Rejected: Only set Running on clear SessionStart | late Stop from the previous lifecycle could still clobber the new status.
Confidence: high
Scope-risk: narrow
Directive: Future Claude hook status mutations must respect the active workspace session before touching claude_code.
Tested: Not run locally per instruction
Not-tested: Full app UI after CI

* Prove Claude clear hook loses running status

The regression exercises the Claude hook handler directly with a SessionStart payload whose source is clear, then sends a late Stop for the previous session. The current handler does not promote the clear boundary to Running or reject stale Stop mutations, so this test is expected to fail before the lifecycle fix.

Directive: Keep this regression on the direct CLI hook path; do not replace it with source-text assertions.

Tested: Not run locally per repository policy.

Not-tested: CI red/green proof pending on GitHub Actions.

* Keep Claude clear sessions authoritative

Claude /clear arrives as a SessionStart source=clear event, but the hook store only remembered routing data. This change makes the store also own the active session for each workspace, promotes clear starts to Running, and ignores visible Stop/Notification/SessionEnd mutations when their session no longer matches the active workspace session.

Constraint: Claude Code documents SessionStart source=clear for /clear lifecycle boundaries.

Rejected: Only set Running on source=clear | old Stop and SessionEnd events could still clobber the new session afterward.

Confidence: high

Scope-risk: narrow

Directive: Visible Claude hook mutations must pass active-session ownership checks before changing sidebar status or notifications.

Tested: Not run locally per repository policy.

Not-tested: CI red/green proof pending on GitHub Actions.

* Allow Claude sessions to advance turns

A visible hook mutation can only be rejected as stale after the active session boundary is known. Keeping a completed turn id active after Stop made the next prompt in the same Claude session look stale before it could promote its own turn.

The Stop path now refreshes the active session with no turn id once the completed turn has been accepted, preserving stale-session protection across /clear while allowing normal multi-turn prompts to re-enter Running. The regression now exercises that two-turn path before the clear boundary.

Constraint: Do not run local tests; CI owns verification for this branch.
Rejected: Ignore turn id in all current-session checks | would weaken stale turn filtering for late Stop and Notification events.
Confidence: high
Scope-risk: narrow
Directive: Do not persist a completed turn id past Stop without proving the next prompt-submit can promote a new turn.
Tested: git diff --check
Not-tested: Local unit/regression tests per project policy

* Remove duplicate Claude clear helper

The branch integration accidentally kept two isClaudeClearSessionStart definitions in CLI/cmux.swift. The duplicate version referenced a non-existent parsedInput.source property, so Swift would reject the file before CI could exercise the hook lifecycle tests.

Keep the existing implementation that reads source from the parsed hook object and delete only the duplicate helper.

Constraint: Fix review-reported compile blocker without changing lifecycle behavior.
Rejected: Add source to ClaudeHookParsedInput | unnecessary for this compile fix and broader than the failing duplicate.
Confidence: high
Scope-risk: narrow
Directive: Keep exactly one Claude clear source helper unless the parsed input model is intentionally extended.
Tested: git diff --check; rg confirms a single isClaudeClearSessionStart definition and no parsedInput.source reference.
Not-tested: Local tests per project policy

* Restore Claude hook compileability after lifecycle merge

The active-session merge left behind the old source-property helper alongside the newer compact-payload helper. Removing the duplicate keeps source=clear detection on the JSON payload and avoids both the redeclaration and missing-property errors.

Constraint: Do not run local tests; CI owns verification for this branch
Rejected: Reintroduce ClaudeHookParsedInput.source | duplicates state already retained in the compact hook payload
Confidence: high
Scope-risk: narrow
Tested: git diff --check; rg verified a single isClaudeClearSessionStart definition and no parsedInput.source references
Not-tested: Local compile/test execution per task policy

* Normalize Claude active-session cleanup keys

The active-session map is keyed by normalized workspace id, so cleanup after consuming a session must use the same normalized key. Otherwise a record containing incidental whitespace could leave a stale active-session entry behind.

Constraint: Address reviewer-reported lifecycle cleanup edge case without changing visible hook behavior.
Rejected: Store raw workspace ids as active map keys | inconsistent with existing upsert normalization and lookup guards.
Confidence: high
Scope-risk: narrow
Directive: Any activeSessionsByWorkspace lookup should use the normalized workspace key, matching insertion.
Tested: git diff --check
Not-tested: Local tests per project policy

* Harden CI Zig downloads against transient upstream failures

CircleCI and the activation workflow both depend on ziglang.org tarballs during remote macOS setup. A transient 500 from that host failed the debug build before any project code compiled, so the install path now retries downloads and avoids unnecessary Homebrew update/cleanup churn on CircleCI.

Constraint: CI must be made green remotely without running local tests or local xcodebuild.

Rejected: Push an empty commit to rerun CI | would leave the same upstream download flake unchanged.

Confidence: high

Scope-risk: narrow

Directive: Keep Zig installer retries in remote CI setup paths; failures here happen before project build logic runs.

Tested: git diff --check

Not-tested: Local tests and local builds not run per repository/user policy.

* Cover stale Claude session-end lifecycle

Greptile identified that stale SessionEnd exercises a different clear-state path than stale Stop. The existing active-session guard already blocks the mutation, so the regression now drives that hook directly and asserts the active /clear session keeps its status, PID, and notifications intact.

Constraint: Do not run local tests; CI is the verification source for this branch.

Rejected: Add another Swift integration test | the existing Python hook harness already executes the CLI handler through the socket path used by CI.

Confidence: high

Scope-risk: narrow

Tested: Not run locally per repo policy.

Not-tested: Local test execution.

* Stop activation CI from stalling on Zig downloads

The activation workflow was cancelled before build because repeated ziglang.org transfers crawled for the full job timeout. Prefer Homebrew's pinned zig@0.15 bottle on macOS runners, then keep the direct tarball path as a bounded fallback with connection, total-time, and minimum-speed limits.

Constraint: The failed check never reached project build or tests; the only failing surface was CI tool bootstrap.

Rejected: Increase the job timeout | it would hide the bootstrap failure and delay feedback.

Confidence: medium

Scope-risk: narrow

Directive: Keep activation workflow tool bootstrap bounded so performance CI reaches the benchmark or fails quickly.

Tested: git diff --check

Not-tested: Local workflow execution, per repository and user instruction.

* Gate Claude session-end cleanup on the consumed workspace

Greptile noted that session-end computed the current-session guard from the fallback workspace while clearing the consumed session's workspace. Move the guard next to the mutation target so stale cleanup and visible cleanup always evaluate the same workspace identity.

Constraint: This is follow-up review hardening on the existing active-session model.

Rejected: Collapse activeSessionsByWorkspace into sessions in this PR | per-workspace current-session lookup is the intended lifecycle boundary for stale event gating.

Confidence: high

Scope-risk: narrow

Directive: SessionEnd visible cleanup must be gated against the workspace being cleared, not an earlier fallback lookup.

Tested: git diff --check

Not-tested: Local test execution, per repository and user instruction.

* Gate Claude session-end cleanup on consumed workspace

A late SessionEnd can be resolved through fallback surface lookup, so the workspace used to find a record is not always the workspace whose visible state would be cleared. Move the staleness check after consume() and evaluate it against the consumed session's workspace, where the clear_status and notification cleanup actually run.

Constraint: Hook events are delivered by short-lived CLI processes and must tolerate stale or partial Claude payloads

Rejected: Keep the pre-consume fallback workspace guard | it can validate one workspace while clearing another

Confidence: high

Scope-risk: narrow

Tested: Added Swift integration regression for stale SessionEnd fallback cleanup

Not-tested: Local tests not run per repository policy

* Make stale Claude session-end test consume the seeded session

Greptile caught that the Swift regression used an unknown session id, so the hook returned before reaching the intended consumed-session visibility guard. Use the seeded stale session id in the SessionEnd payload so the test exercises consume(), then verifies that stale visible cleanup is blocked.

Constraint: Address high-priority review feedback without running local tests.

Rejected: Leave Python-only coverage | the Swift regression would continue passing for the wrong reason.

Confidence: high

Scope-risk: narrow

Directive: Stale session-end regressions should consume a known stale session before asserting visible cleanup is skipped.

Tested: git diff --check

Not-tested: Local tests per repository and user instruction

* Cover fallback Claude session-end consumption

The stale SessionEnd regression should prove the handler consumed the stale session through fallback lookup before deciding whether visible state may be cleared. Use an unknown late session id and assert the seeded stale session is removed from the store, so the test cannot pass without exercising the consumed-workspace guard.

Constraint: Review feedback flagged the prior Swift regression as able to pass without covering the intended guard

Rejected: Use the stored stale session id directly | that only covers the ordinary mapped-session stale path

Confidence: high

Scope-risk: narrow

Tested: Not run locally per repository policy; CI will run the Swift regression

Not-tested: Local XCTest execution

* Keep Claude clear ownership panel-scoped

The clear SessionStart path now owns the active Claude boundary only for explicit clear events, so late startup/resume SessionStart events from the previous session cannot reclaim the workspace before their stale Stop or SessionEnd arrives. The same clear path now passes the resolved surface id into status updates so split panels receive the Running state in the intended pane.

Constraint: Local test execution is disallowed by repository policy; CI remains the behavioral gate.

Rejected: Let every SessionStart mark active | late non-clear events can overwrite the clear boundary.

Rejected: Drop fail-open isCurrent behavior | transient store errors should not hide legitimate current status updates.

Confidence: medium

Scope-risk: moderate

Directive: Do not let non-clear Claude SessionStart events replace an explicit /clear active boundary without adding event ordering metadata.

Tested: python3 -m py_compile tests/test_claude_hook_clear_running_status.py; git diff --check; conflict marker scan.

Not-tested: Local Swift/unit/UI test execution per repo policy.

* Protect Claude clear state from stale session cleanup

Late hook events can arrive after an explicit /clear boundary. The SessionStart handler now skips PID registration when the event is stale against the active session, and SessionEnd consumption preserves the active session when the incoming turn id is older than the stored active turn.

Constraint: Local test execution is disallowed by repository policy; CI remains the behavioral gate.

Rejected: Clear active ownership before checking currentness | same-session stale SessionEnd would fail open and apply cleanup.

Rejected: Keep prefix-only command assertions | option ordering changes would make the regression test brittle.

Confidence: medium

Scope-risk: moderate

Directive: Do not consume a Claude session or replace its PID from a hook event that is stale relative to active session/turn state.

Tested: python3 -m py_compile tests/test_claude_hook_clear_running_status.py; git diff --check; conflict marker scan.

Not-tested: Local Swift/unit/UI test execution per repo policy.

* Allow new Claude sessions to replace stopped owners

A stopped Claude turn must keep the same session eligible for the next turn, but it must not strand the workspace if that process exits before session-end. Mark stopped ownership as replaceable and let only session activation paths use that escape hatch; clear-session ownership remains non-replaceable so stale pre-clear events stay blocked. Session-end fallback cleanup now checks the consumed session id so missing input session ids do not fail open.\n\nConstraint: /clear SessionStart must continue to suppress stale pre-clear startup, stop, and session-end events\nRejected: Clear active ownership on Stop | breaks same-session multi-turn prompt-submit currentness\nConfidence: medium\nScope-risk: narrow\nTested: git diff --check; conflict-marker scan\nNot-tested: local XCTest per repo policy; CI will run cmux unit regressions

* Prove stale Kitty keyboard state leaks CSI-u key bytes

The regression exercises a hosted Ghostty terminal, leaves Kitty keyboard protocol enabled as a crashed TUI would, mirrors the clear-history socket handler clear_screen path, and captures raw PTY stdin bytes for a plain c key. Current behavior should encode CSI-u instead of a single ASCII byte, making the test fail until the protocol state is reset at the shell prompt boundary.

Constraint: Regression must cover PTY input bytes, not source text shape
Confidence: high
Scope-risk: narrow
Directive: Keep this test on the real ghostty_surface_key path; sendText alone bypasses the keyboard encoder
Tested: Manual current-main repro captured c9;1:3uc9;1:3uc9;1:3u after Kitty enable plus clear-history
Not-tested: Local unit execution deferred to CI per requested red/green workflow

* Reset stale Kitty keyboard mode at prompt boundaries

A crashed TUI can leave Ghostty's Kitty keyboard protocol stack pushed after clear-history, causing normal shell input to be encoded as CSI-u. Resetting the stack from the shell prompt hook makes the prompt boundary the ownership point for returning interactive shells to plain byte input.

Constraint: Fix must run through shell integration because Ghostty keeps protocol state inside the terminal surface

Rejected: Reset only in clear-history socket path | stale state also leaks after any crashed TUI returns to prompt

Confidence: high

Scope-risk: narrow

Directive: Keep prompt-boundary reset paired across bash and zsh integrations

Tested: Not run locally per repository testing policy; regression added in prior commit

- cmux --help "Agent Help" now tells agents where Ghostty config lives
  and that reload-config picks it up live.
- cmux docs settings, cmux settings path, cmux config --help now list
  ~/.config/ghostty/config as a related (not cmux-owned) location and
  describe reload-config's actual scope.
- cmux schema sidebarAppearance.tintOpacity description now notes it's
  sidebar-only, and points to Ghostty background-opacity / blur for
  terminal transparency.
- skills/cmux/SKILL.md mirrors the wording.

* Align ghostty_config JSON shape across CLI surfaces

Cursor Bugbot and Greptile both flagged that `cmux settings path --json`
emitted `ghostty_config` as a string while `cmux docs settings --json`
emitted it as an object {path, note}. An agent reading both outputs with
the same key expectation would have to special-case the type.

Standardize on the object shape with `path` and `note` in both, matching
docsPayload. This is the agent-discoverability path the PR is trying to
make reliable, so making the shape consistent is on-purpose.

* Use canonical Ghostty config key background-blur (not background-blur-radius)

CodeRabbit flagged that `background-blur-radius` is outdated. Verified
against the Ghostty submodule at ghostty/src/config/Config.zig: line 70
declares `background-blur-radius` as a compatibilityRenamed alias for
`background-blur`. The current canonical key is `background-blur` and it
accepts the same integer value (e.g. `background-blur = 20`).

Update the two docs that introduced the alias name:
- skills/cmux/SKILL.md
- web/data/cmux.schema.json (sidebarAppearance.tintOpacity description)

* Menubar global search P1 (#3908)

* Ship local global search as a remappable menubar flow

Phase 1 needs browser and markdown value without terminal scrollback, so the index owns durable FTS5 upserts while AppDelegate keeps one navigation path from palette rows to focused panels. The global shortcut is wired through the existing shortcut settings instead of a standalone Carbon shim so Settings and cmux.json remain authoritative.

Constraint: Phase 1 excludes Ghostty terminal scrollback capture

Constraint: User required no local test execution and no reload before CI is green

Rejected: Hardcoded GlobalSearchHotkey shim | violates KeyboardShortcutSettings policy

Confidence: medium

Scope-risk: broad

Directive: Keep future terminal capture feeding SearchIndex documents through GlobalSearchCoordinator rather than adding another palette/navigation path

Tested: git diff --check; python3 -m json.tool Resources/Localizable.xcstrings; python3 -m json.tool web/data/cmux.schema.json; plutil -lint GhosttyTabs.xcodeproj/project.pbxproj

Not-tested: Local unit/UI tests and tagged app launch per task constraints

* Remove duplicate search refresh work

Cursor review pointed out that the menubar toggle and palette onAppear both refreshed the live index. Keeping the refresh in the palette lifecycle avoids resetting browser debounce tasks while still indexing each time the palette opens, and removing the unused workspace delete API keeps the storage surface honest.

Constraint: Review feedback came from PR #3908 after the first CI pass started

Rejected: Keep both refresh calls | causes avoidable debounce cancellation and slower browser result availability

Confidence: high

Scope-risk: narrow

Directive: Add workspace-level deletion only when a real workspace teardown caller is wired

* Inherit stdin in backgrounded ssh inside startup wrapper (#4135)

* Add regression test for SSH startup wrapper dropping stdin

After PR #3786 backgrounded the ssh invocation inside the startup
wrapper for signal/reconnect handling, `cmux ssh <host>` sessions
stopped forwarding keystrokes from the surface PTY to the remote
shell. Output flowed back (the remote prompt rendered in cmux UI),
but anything typed never reached zsh on the other side, which sat
blocked in `do_poll` on the remote pts.

Root cause: POSIX sh redirects stdin of an async command (`&`) to
/dev/null when job control is off — the default for the `/bin/sh -c …`
that runs the startup wrapper. Without an explicit `<&0` on the
`&`'d ssh line, the local PTY stdin is silently dropped.

This commit adds the failing regression test. The fix follows in
the next commit so CI can prove the test catches the bug.

* Inherit stdin in backgrounded ssh inside startup wrapper

PR #3786 wrapped the ssh invocation in `while :; do … & wait` to enable
SIGHUP/INT/TERM trap handling and reconnect-on-exit-255. Backgrounding
ssh, however, drops its stdin: POSIX sh redirects fd 0 of any async
command to /dev/null when job control is off, which is the default for
the `/bin/sh -c …` host that runs this wrapper.

As a result, output from the remote still flowed back to the surface
PTY (ssh's stdout/stderr stayed wired) but the user's keystrokes never
reached the remote — they hit ttysNNN on the Mac side, kernel echoed
them locally, but ssh's stdin was /dev/null so nothing was forwarded.
zsh on the far side sat in `do_poll` forever.

Explicit `<&0` on both the `command` line and the `( … )` shell-snippet
form overrides the POSIX default and re-attaches the wrapper's own
stdin to the backgrounded ssh process.

Verified with the regression test added in the previous commit, plus
manual repro on Darwin:

    /bin/sh -c 'cat &  wait'           # cat's fd 0 → /dev/null (bug)
    /bin/sh -c 'cat <&0 &  wait'       # cat's fd 0 → parent stdin (fix)

* Add docs search

Adds localized Pagefind docs search with heading anchors and section-aware results.

* Fix Swift interpolation escape in SSH stdin regression test (#4154)

`testSSHStartupForwardsStdinToBackgroundedSSH` used `\"<empty>\"` inside a
`\(...)` string interpolation. Swift parses `\"` as the end of the outer
literal, breaking compilation of cmuxTests on main:

    Cannot find ')' to match opening '(' in string interpolation
    Unterminated string literal

That kept `ci/circleci: macos-unit-tests` red on main after #4135 even
though `macos-debug-build` and `macos-release-build` still passed (the
test target was the only thing affected). The runtime fix (`<&0` on the
backgrounded ssh) is unchanged and was verified end-to-end on a cloud Mac.

Inside an interpolation, the string is already a Swift expression and
literal quotes are unescaped; drop the four backslashes.

* Fix #3807: bring notification CLI to panel parity (#3811)

* Prove notification CLI parity is missing

Add behavior-level coverage for the missing notification socket and CLI actions before implementing them. The tests drive V2 notification action methods, CLI subcommands, extended list fields, and the UI open-notification flow so CI can show the pre-fix gap.

Constraint: Regression tests must be committed before the implementation for issue #3807

Constraint: Local Swift tests are not run in this repo; verification is through CI

Confidence: high

Scope-risk: narrow

Tested: git diff --check

Not-tested: Swift/XCUITest execution; intentionally deferred to CI

* Make notification actions scriptable from the CLI

The notifications panel already owned the behavior for dismissing, marking read, opening, and jumping to unread rows. This wires the socket and CLI to those existing store/AppDelegate paths, extends list output with panel metadata, and documents the new command surface without introducing a second notification action model.

Constraint: Existing Notifications page behavior must remain the source of truth

Constraint: Direct xcodebuild and local Swift/XCUITest runs are forbidden in this workspace

Rejected: Duplicate CLI-side focus or read-state logic | would diverge from AppDelegate.openNotification and TerminalNotificationStore semantics

Confidence: medium

Scope-risk: moderate

Tested: git diff --check

Tested: jq empty Resources/Localizable.xcstrings

Tested: python3 -m json.tool Resources/Localizable.xcstrings

Not-tested: Swift unit/UI execution; deferred to CI per repo policy

* Make notification CI compile under strict concurrency

The notification parity implementation introduced a shared formatter on a main-actor type and a test helper that crossed actor boundaries through escaping closures. This keeps the socket behavior unchanged while making date formatting local to the main-actor call path and keeping the XCTest socket request helper from capturing actor-isolated state in the background request closure.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace

Rejected: Run xcodebuild locally to confirm | user explicitly warned direct xcodebuild can deadlock the machine

Confidence: medium

Scope-risk: narrow

Tested: git diff --check

Tested: jq empty Resources/Localizable.xcstrings

Not-tested: Swift compilation and XCTest execution; deferred to CI

* Make notification parity actions atomic and exact

Review feedback exposed two behavior risks in the notification parity path: bulk dismissal was implemented as client-side list-and-loop work, and jump-to-unread could report one unread notification while opening a later valid one. The server now owns already-read dismissal as a single V2 action, the jump helper returns the notification it actually opened, and event/list parsing details match those server semantics.

Constraint: Notification action logic must reuse the existing store and AppDelegate paths

Rejected: Split TerminalController into new controllers in this PR | broad refactor is unrelated to issue #3807 and would obscure the parity fix

Confidence: medium

Scope-risk: moderate

Tested: git diff --check

Tested: jq empty Resources/Localizable.xcstrings

Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace instructions

* Expose app test symbols to CLI notification coverage

The integration regression exercises real app-backed notification state through the CLI harness, so the test target must import the built app module the same way the socket action tests do.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace
Rejected: Verify with xcodebuild locally | user explicitly forbids direct xcodebuild
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI

* Make notification list and dismiss payloads stable

Review caught two small contract hazards in the new notification RPC surface: the dismiss result used mixed JSON types, and a pipe in the appended tab title could shift the legacy list parser. The server now reports dismissals as counts consistently and escapes only the new trailing list field, with the CLI decoding it after structural parsing.

Constraint: The V1 list response remains pipe-delimited for backward compatibility, so only newly appended trailing fields can be encoded without changing old parser behavior
Rejected: Replace list_notifications with JSON-only output | existing V1 parsers depend on the line format
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace policy

* Return async notification socket responses from tests

CircleCI caught a compile-only issue in the async V2 test helper: the continuation result was awaited but not returned from the method that promises a response dictionary. Returning the continuation value restores the helper contract without changing the exercised socket behavior.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace
Rejected: Verify with local xcodebuild | user explicitly forbids direct xcodebuild
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI

* Avoid blocking notification CLI integration sockets

The integration regression has to create AppKit-backed notification state on the main actor, but running the CLI subprocess synchronously there can block the socket handler's main-actor store mutations. The test now awaits subprocess work on a background queue and verifies read state through the same CLI list path.

Constraint: Socket notification handlers intentionally hop to the main actor for store and AppDelegate work
Rejected: Run the CLI synchronously from the main actor | it can deadlock the in-process socket server during tests
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace policy

* Harden notification CLI response contracts

The notification parity path now distinguishes new list-notification trailer fields from old pipe-heavy bodies, rejects surface-only mark-read selectors, and returns post-open read state by marking through the shared store path after a successful focus action.

Constraint: list_notifications remains a legacy pipe-delimited protocol, so the new trailer needs its own discriminator while older body parsing keeps joining payload[6...]
Rejected: Add a third list_notifications sentinel field | the issue asked for exactly the two appended fields
Rejected: Rely on AppDelegate delayed mark-read for socket JSON | CLI callers need the open response and subsequent list output to reflect the explicit action
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI per workspace policy

* Make CLI integration helper capture explicit self

CircleCI's Swift compile step requires explicit self when the background subprocess closure calls the test helper method. This keeps the deadlock fix intact while satisfying Swift capture rules.

Constraint: Local Swift tests and direct xcodebuild are explicitly forbidden in this workspace
Rejected: Verify with local xcodebuild | user explicitly forbids direct xcodebuild
Confidence: high
Scope-risk: narrow
Tested: git diff --check
Tested: jq empty Resources/Localizable.xcstrings
Not-tested: Swift compilation and XCTest execution; deferred to CI

* Make CLI presentation flags order-independent

Users naturally put presentation flags next to the command they are inspecting. Normalize --json and --id-format after command selection so docs examples such as cmux list-notifications --json produce JSON while still preserving literal flag-looking values for command options.

Constraint: Do not run reload.sh before CI is green; never run bare xcodebuild.

Rejected: Documentation-only correction | leaves copy-pasted command behavior surprising.

Rejected: Notification-only --json handling | repeats the same parser split for future JSON-capable commands.

Confidence: medium

Scope-risk: moderate

Directive: Keep presentation flag parsing centralized; update commandOptionsWithValues when adding value-taking command options.

Tested: git diff --check

Not-tested: Local XCTest/build per repo policy; CI will verify.

* Prevent display-link crash from terminal portal layout reentry (#3885)

* Pin portal sync deferral during SwiftUI host callbacks

The silent-exit crash path points at SwiftUI/AppKit layout recursion reaching a CATransaction display-link flush. This test locks the intended invariant: geometry callbacks originating from the SwiftUI NSViewRepresentable host must defer portal reconciliation instead of forcing immediate AppKit layout, even while an interactive resize is active.

Constraint: Local tests are intentionally not run in this repository; CI owns regression proof.\nRejected: Assert on source text or unified-log contents | timing-dependent and not executable through the policy seam.\nConfidence: medium\nScope-risk: narrow\nDirective: Keep immediate portal flushing owned by external AppKit resize observers, not SwiftUI host callbacks.\nTested: Not run locally per repository policy and user instruction.\nNot-tested: Full multi-session crash reproduction is timing-dependent and not deterministic.

* Prevent portal layout reentry from terminal host callbacks

The terminal NSViewRepresentable host was allowed to bind into the window portal and synchronously flush AppKit layout from update/layout callbacks. That made SwiftUI's own host layout and the external terminal portal both believe they could drive geometry in the same render turn, matching the NSHostingView reentrant-layout warnings reported before the CATransaction display-link abort.\n\nThe portal now treats SwiftUI host callbacks as state capture only: they register the binding and schedule the portal owner to reconcile geometry after the current render turn. Immediate geometry flushing remains available to the portal's external AppKit resize observers, which are outside SwiftUI body/layout evaluation. The launch path also records clean exits and posts a one-time TerminalNotificationStore breadcrumb when a newer ghostty Breakpad envelope is found after an unclean exit.

Constraint: Local tests and app builds are not run before CI for this branch; verification is delegated to CI, then the required tagged reload.\nRejected: Wrap the CATransaction/display-link exception in @try/@catch | it would hide AppKit's abort symptom without removing the reentrant layout owner split.\nRejected: Keep immediate sync during interactive SwiftUI host callbacks | still allows layoutSubtreeIfNeeded inside the representable layout/update path.\nConfidence: medium\nScope-risk: moderate\nDirective: SwiftUI/AppKit host callbacks must not force terminal portal layout synchronously; add external observer paths for any future immediate resize flushing.\nTested: git diff --check; jq empty Resources/Localizable.xcstrings\nNot-tested: Local XCTest/build/repro per repository and user instructions; 75-minute multi-session crash reproduction is not deterministic.

* Record clean-exit breadcrumb after teardown

The crash breadcrumb should compare Breakpad envelopes against the last successfully completed termination path. Recording the timestamp after teardown avoids marking an exit clean before session persistence, process cleanup, and notification cleanup have finished.

Constraint: This is a follow-up correctness tweak before CI settled.\nRejected: Keep the timestamp at the start of applicationWillTerminate | a crash during termination cleanup could suppress the next-launch breadcrumb.\nConfidence: high\nScope-risk: narrow\nDirective: Only update the clean-exit timestamp after teardown work that must complete for a clean quit.\nTested: git diff --check; jq empty Resources/Localizable.xcstrings\nNot-tested: Local tests/builds per repository and user instructions.

* Defer first portal install from SwiftUI callbacks

A deferred SwiftUI host bind could still create the WindowTerminalPortal for the first time, and the initializer previously installed the host with an immediate layout flush. Threading the same deferral flag through portal creation keeps the invariant complete: representable update/layout callbacks never synchronously flush terminal portal layout, even on first bind.

Constraint: Must preserve immediate install behavior for non-SwiftUI external portal callers
Rejected: Assume portals already exist before host callbacks | first terminal bind in a new window can create one
Confidence: high
Scope-risk: narrow
Directive: Any future portal creation path from SwiftUI callbacks must carry deferred synchronization through initialization
Tested: git diff --check; jq empty Resources/Localizable.xcstrings
Not-tested: Local tests/builds per repository and user instructions

* Move crash breadcrumb work out of launch hot path

The crash breadcrumb scanner is pure Foundation logic, so it now lives in its own source file and performs the crash-directory scan from a detached utility task. App launch only schedules the check once, then posts the existing localized notification after the background scan returns to the main actor. The terminal host geometry policy is also simplified to make the always-deferred invariant explicit at the call site.

Constraint: Local build/tests are intentionally skipped until CI completes per issue instructions
Rejected: Keep synchronous directory enumeration in AppDelegate.configure | startup should not block on crash artifact I/O
Rejected: Preserve the dead immediate portal sync branch | host callbacks are never allowed to force layout synchronously
Confidence: high
Scope-risk: narrow

* Keep Claude Running after clear (#3631)

* Prove Claude clear hook loses running status

The regression exercises the Claude hook handler directly with a SessionStart payload whose source is clear, then sends a late Stop for the previous session. The current handler does not promote the clear boundary to Running or reject stale Stop mutations, so this test is expected to fail before the lifecycle fix.

Constraint: Tests must exercise the hook handler directly rather than driving the full app.

Confidence: high

Scope-risk: narrow

Directive: Keep this regression on the direct CLI hook path; do not replace it with source-text assertions.

Tested: Not run locally per repository policy.

Not-tested: CI red/green proof pending on GitHub Actions.

* Prove Claude clear should own running status

Add hook-level regression coverage for Claude Code /clear. The tests drive the bundled CLI against a mock cmux socket so CI proves SessionStart(source=clear) must set the visible Running status and a prior session Stop must not clobber that fresh lifecycle.

Constraint: Local tests are intentionally not run; CI owns test execution for this task.
Confidence: high
Scope-risk: narrow
Tested: Not run locally per instruction
Not-tested: Full app UI repro under CI

* Ignore stale Claude hook events after clear

Claude /clear starts a fresh hook lifecycle but the sidebar status key is shared at the workspace level. Persist the active Claude session per workspace, promote clear SessionStart to a visible Running state, and ignore teardown or notification mutations from sessions that are no longer current.

Constraint: Claude Code emits /clear as SessionStart(source=clear).
Rejected: Only set Running on clear SessionStart | late Stop from the previous lifecycle could still clobber the new status.
Confidence: high
Scope-risk: narrow
Directive: Future Claude hook status mutations must respect the active workspace session before touching claude_code.
Tested: Not run locally per instruction
Not-tested: Full app UI after CI

* Prove Claude clear hook loses running status

The regression exercises the Claude hook handler directly with a SessionStart payload whose source is clear, then sends a late Stop for the previous session. The current handler does not promote the clear boundary to Running or reject stale Stop mutations, so this test is expected to fail before the lifecycle fix.

Constraint: Tests must exercise the hook handler directly rather than driving the full app.

Confidence: high

Directive: Keep this regression on the direct CLI hook path; do not replace it with source-text assertions.

Tested: Not run locally per repository policy.

Not-tested: CI red/green proof pending on GitHub Actions.

* Keep Claude clear sessions authoritative

Claude /clear arrives as a SessionStart source=clear event, but the hook store only remembered routing data. This change makes the store also own the active session for each workspace, promotes clear starts to Running, and ignores visible Stop/Notification/SessionEnd mutations when their session no longer matches the active workspace session.

Constraint: Claude Code documents SessionStart source=clear for /clear lifecycle boundaries.

Rejected: Only set Running on source=clear | old Stop and SessionEnd events could still clobber the new session afterward.

Confidence: high

Scope-risk: narrow

Directive: Visible Claude hook mutations must pass active-session ownership checks before changing sidebar status or notifications.

Tested: Not run locally per repository policy.

Not-tested: CI red/green proof pending on GitHub Actions.

* Allow Claude sessions to advance turns

A visible hook mutation can only be rejected as stale after the active session boundary is known. Keeping a completed turn id active after Stop made the next prompt in the same Claude session look stale before it could promote its own turn.

The Stop path now refreshes the active session with no turn id once the completed turn has been accepted, preserving stale-session protection across /clear while allowing normal multi-turn prompts to re-enter Running. The regression now exercises that two-turn path before the clear boundary.

Constraint: Do not run local tests; CI owns verification for this branch.
Rejected: Ignore turn id in all current-session checks | would weaken stale turn filtering for late Stop and Notification events.
Confidence: high
Scope-risk: narrow
Directive: Do not persist a completed turn id past Stop without proving the next prompt-submit can promote a new turn.
Tested: git diff --check
Not-tested: Local unit/regression tests per project policy

* Remove duplicate Claude clear helper

The branch integration accidentally kept two isClaudeClearSessionStart definitions in CLI/cmux.swift. The duplicate version referenced a non-existent parsedInput.source property, so Swift would reject the file before CI could exercise the hook lifecycle tests.

Keep the existing implementation that reads source from the parsed hook object and delete only the duplicate helper.

Constraint: Fix review-reported compile blocker without changing lifecycle behavior.
Rejected: Add source to ClaudeHookParsedInput | unnecessary for this compile fix and broader than the failing duplicate.
Confidence: high
Scope-risk: narrow
Directive: Keep exactly one Claude clear source helper unless the parsed input model is intentionally extended.
Tested: git diff --check; rg confirms a single isClaudeClearSessionStart definition and no parsedInput.source reference.
Not-tested: Local tests per project policy

* Restore Claude hook compileability after lifecycle merge

The active-session merge left behind the old source-property helper alongside the newer compact-payload helper. Removing the duplicate keeps source=clear detection on the JSON payload and avoids both the redeclaration and missing-property errors.

Constraint: Do not run local tests; CI owns verification for this branch
Rejected: Reintroduce ClaudeHookParsedInput.source | duplicates state already retained in the compact hook payload
Confidence: high
Scope-risk: narrow
Tested: git diff --check; rg verified a single isClaudeClearSessionStart definition and no parsedInput.source references
Not-tested: Local compile/test execution per task policy

* Normalize Claude active-session cleanup keys

The active-session map is keyed by normalized workspace id, so cleanup after consuming a session must use the same normalized key. Otherwise a record containing incidental whitespace could leave a stale active-session entry behind.

Constraint: Address reviewer-reported lifecycle cleanup edge case without changing visible hook behavior.
Rejected: Store raw workspace ids as active map keys | inconsistent with existing upsert normalization and lookup guards.
Confidence: high
Scope-risk: narrow
Directive: Any activeSessionsByWorkspace lookup should use the normalized workspace key, matching insertion.
Tested: git diff --check
Not-tested: Local tests per project policy

* Harden CI Zig downloads against transient upstream failures

CircleCI and the activation workflow both depend on ziglang.org tarballs during remote macOS setup. A transient 500 from that host failed the debug build before any project code compiled, so the install path now retries downloads and avoids unnecessary Homebrew update/cleanup churn on CircleCI.

Constraint: CI must be made green remotely without running local tests or local xcodebuild.

Rejected: Push an empty commit to rerun CI | would leave the same upstream download flake unchanged.

Confidence: high

Scope-risk: narrow

Directive: Keep Zig installer retries in remote CI setup paths; failures here happen before project build logic runs.

Tested: git diff --check

Not-tested: Local tests and local builds not run per repository/user policy.

* Cover stale Claude session-end lifecycle

Greptile identified that stale SessionEnd exercises a different clear-state path than stale Stop. The existing active-session guard already blocks the mutation, so the regression now drives that hook directly and asserts the active /clear session keeps its status, PID, and notifications intact.

Constraint: Do not run local tests; CI is the verification source for this branch.

Rejected: Add another Swift integration test | the existing Python hook harness already executes the CLI handler through the socket path used by CI.

Confidence: high

Scope-risk: narrow

Tested: Not run locally per repo policy.

Not-tested: Local test execution.

* Stop activation CI from stalling on Zig downloads

The activation workflow was cancelled before build because repeated ziglang.org transfers crawled for the full job timeout. Prefer Homebrew's pinned zig@0.15 bottle on macOS runners, then keep the direct tarball path as a bounded fallback with connection, total-time, and minimum-speed limits.

Constraint: The failed check never reached project build or tests; the only failing surface was CI tool bootstrap.

Rejected: Increase the job timeout | it would hide the bootstrap failure and delay feedback.

Confidence: medium

Scope-risk: narrow

Directive: Keep activation workflow tool bootstrap bounded so performance CI reaches the benchmark or fails quickly.

Tested: git diff --check

Not-tested: Local workflow execution, per repository and user instruction.

* Gate Claude session-end cleanup on the consumed workspace

Greptile noted that session-end computed the current-session guard from the fallback workspace while clearing the consumed session's workspace. Move the guard next to the mutation target so stale cleanup and visible cleanup always evaluate the same workspace identity.

Constraint: This is follow-up review hardening on the existing active-session model.

Rejected: Collapse activeSessionsByWorkspace into sessions in this PR | per-workspace current-session lookup is the intended lifecycle boundary for stale event gating.

Confidence: high

Scope-risk: narrow

Directive: SessionEnd visible cleanup must be gated against the workspace being cleared, not an earlier fallback lookup.

Tested: git diff --check

Not-tested: Local test execution, per repository and user instruction.

* Gate Claude session-end cleanup on consumed workspace

A late SessionEnd can be resolved through fallback surface lookup, so the workspace used to find a record is not always the workspace whose visible state would be cleared. Move the staleness check after consume() and evaluate it against the consumed session's workspace, where the clear_status and notification cleanup actually run.

Constraint: Hook events are delivered by short-lived CLI processes and must tolerate stale or partial Claude payloads

Rejected: Keep the pre-consume fallback workspace guard | it can validate one workspace while clearing another

Confidence: high

Scope-risk: narrow

Tested: Added Swift integration regression for stale SessionEnd fallback cleanup

Not-tested: Local tests not run per repository policy

* Make stale Claude session-end test consume the seeded session

Greptile caught that the Swift regression used an unknown session id, so the hook returned before reaching the intended consumed-session visibility guard. Use the seeded stale session id in the SessionEnd payload so the test exercises consume(), then verifies that stale visible cleanup is blocked.

Constraint: Address high-priority review feedback without running local tests.

Rejected: Leave Python-only coverage | the Swift regression would continue passing for the wrong reason.

Confidence: high

Scope-risk: narrow

Directive: Stale session-end regressions should consume a known stale session before asserting visible cleanup is skipped.

Tested: git diff --check

Not-tested: Local tests per repository and user instruction

* Cover fallback Claude session-end consumption

The stale SessionEnd regression should prove the handler consumed the stale session through fallback lookup before deciding whether visible state may be cleared. Use an unknown late session id and assert the seeded stale session is removed from the store, so the test cannot pass without exercising the consumed-workspace guard.

Constraint: Review feedback flagged the prior Swift regression as able to pass without covering the intended guard

Rejected: Use the stored stale session id directly | that only covers the ordinary mapped-session stale path

Confidence: high

Scope-risk: narrow

Tested: Not run locally per repository policy; CI will run the Swift regression

Not-tested: Local XCTest execution

* Keep Claude clear ownership panel-scoped

The clear SessionStart path now owns the active Claude boundary only for explicit clear events, so late startup/resume SessionStart events from the previous session cannot reclaim the workspace before their stale Stop or SessionEnd arrives. The same clear path now passes the resolved surface id into status updates so split panels receive the Running state in the intended pane.

Constraint: Local test execution is disallowed by repository policy; CI remains the behavioral gate.

Rejected: Let every SessionStart mark active | late non-clear events can overwrite the clear boundary.

Rejected: Drop fail-open isCurrent behavior | transient store errors should not hide legitimate current status updates.

Confidence: medium

Scope-risk: moderate

Directive: Do not let non-clear Claude SessionStart events replace an explicit /clear active boundary without adding event ordering metadata.

Tested: python3 -m py_compile tests/test_claude_hook_clear_running_status.py; git diff --check; conflict marker scan.

Not-tested: Local Swift/unit/UI test execution per repo policy.

* Protect Claude clear state from stale session cleanup

Late hook events can arrive after an explicit /clear boundary. The SessionStart handler now skips PID registration when the event is stale against the active session, and SessionEnd consumption preserves the active session when the incoming turn id is older than the stored active turn.

Constraint: Local test execution is disallowed by repository policy; CI remains the behavioral gate.

Rejected: Clear active ownership before checking currentness | same-session stale SessionEnd would fail open and apply cleanup.

Rejected: Keep prefix-only command assertions | option ordering changes would make the regression test brittle.

Confidence: medium

Scope-risk: moderate

Directive: Do not consume a Claude session or replace its PID from a hook event that is stale relative to active session/turn state.

Tested: python3 -m py_compile tests/test_claude_hook_clear_running_status.py; git diff --check; conflict marker scan.

Not-tested: Local Swift/unit/UI test execution per repo policy.

* Allow new Claude sessions to replace stopped owners

A stopped Claude turn must keep the same session eligible for the next turn, but it must not strand the workspace if that process exits before session-end. Mark stopped ownership as replaceable and let only session activation paths use that escape hatch; clear-session ownership remains non-replaceable so stale pre-clear events stay blocked. Session-end fallback cleanup now checks the consumed session id so missing input session ids do not fail open.\n\nConstraint: /clear SessionStart must continue to suppress stale pre-clear startup, stop, and session-end events\nRejected: Clear active ownership on Stop | breaks same-session multi-turn prompt-submit currentness\nConfidence: medium\nScope-risk: narrow\nTested: git diff --check; conflict-marker scan\nNot-tested: local XCTest per repo policy; CI will run cmux unit regressions

* Reset Kitty keyboard mode at shell prompt boundaries (#3870)

* Prove stale Kitty keyboard state leaks CSI-u key bytes

The regression exercises a hosted Ghostty terminal, leaves Kitty keyboard protocol enabled as a crashed TUI would, mirrors the clear-history socket handler clear_screen path, and captures raw PTY stdin bytes for a plain c key. Current behavior should encode CSI-u instead of a single ASCII byte, making the test fail until the protocol state is reset at the shell prompt boundary.

Constraint: Regression must cover PTY input bytes, not source text shape
Confidence: high
Scope-risk: narrow
Directive: Keep this test on the real ghostty_surface_key path; sendText alone bypasses the keyboard encoder
Tested: Manual current-main repro captured c9;1:3uc9;1:3uc9;1:3u after Kitty enable plus clear-history
Not-tested: Local unit execution deferred to CI per requested red/green workflow

* Reset stale Kitty keyboard mode at prompt boundaries

A crashed TUI can leave Ghostty's Kitty keyboard protocol stack pushed after clear-history, causing normal shell input to be encoded as CSI-u. Resetting the stack from the shell prompt hook makes the prompt boundary the ownership point for returning interactive shells to plain byte input.

Constraint: Fix must run through shell integration because Ghostty keeps protocol state inside the terminal surface

Rejected: Reset only in clear-history socket path | stale state also leaks after any crashed TUI returns to prompt

Confidence: high

Scope-risk: narrow

Directive: Keep prompt-boundary reset paired across bash and zsh integrations

Tested: Not run locally per repository testing policy; regression added in prior commit

Not-tested: CI not yet completed

* Clarify Kitty reset fixture failures

The stale keyboard regression now fails at the fixture boundary if the zsh integration does not emit the expected reset bytes, instead of falling through to a misleading PTY byte mismatch.

Constraint: Repository policy forbids local test execution for this PR loop

Confidence: high

Scope-risk: narrow

Tested: Not run locally per repository policy; CI will run the affected XCTest

Not-tested: Local XCTest execution

* Clarify in cmux --help that reload-config covers Ghostty config too (#4060)

* Clarify cmux help that reload-config covers Ghostty config too

`cmux reload-config` reloads BOTH ~/.config/cmux/cmux.json and Ghostty
config (~/.config/ghostty/config) and refreshes terminals in place, but
the help/docs only mentioned cmux.json. Agents (and humans) reading the
help would think they had to restart cmux after editing Ghostty config.

- cmux --help "Agent Help" now tells agents where Ghostty config lives
  and that reload-config picks it up live.
- cmux docs settings, cmux settings path, cmux config --help now list
  ~/.config/ghostty/config as a related (not cmux-owned) location and
  describe reload-config's actual scope.
- cmux schema sidebarAppearance.tintOpacity description now notes it's
  sidebar-only, and points to Ghostty background-opacity / blur for
  terminal transparency.
- skills/cmux/SKILL.md mirrors the wording.

* Align ghostty_config JSON shape across CLI surfaces

Cursor Bugbot and Greptile both flagged that `cmux settings path --json`
emitted `ghostty_config` as a string while `cmux docs settings --json`
emitted it as an object {path, note}. An agent reading both outputs with
the same key expectation would have to special-case the type.

Standardize on the object shape with `path` and `note` in both, matching
docsPayload. This is the agent-discoverability path the PR is trying to
make reliable, so making the shape consistent is on-purpose.

* Use canonical Ghostty config key background-blur (not background-blur-radius)

CodeRabbit flagged that `background-blur-radius` is outdated. Verified
against the Ghostty submodule at ghostty/src/config/Config.zig: line 70
declares `background-blur-radius` as a compatibilityRenamed alias for
`background-blur`. The current canonical key is `background-blur` and it
accepts the same integer value (e.g. `background-blur = 20`).

Update the two docs that introduced the alias name:
- skills/cmux/SKILL.md
- web/data/cmux.schema.json (sidebarAppearance.tintOpacity description)

* Menubar global search P1 (#3908)

* Ship local global search as a remappable menubar flow

Phase 1 needs browser and markdown value without terminal scrollback, so the index owns durable FTS5 upserts while AppDelegate keeps one navigation path from palette rows to focused panels. The global shortcut is wired through the existing shortcut settings instead of a standalone Carbon shim so Settings and cmux.json remain authoritative.

Constraint: Phase 1 excludes Ghostty terminal scrollback capture

Constraint: User required no local test execution and no reload before CI is green

Rejected: Hardcoded GlobalSearchHotkey shim | violates KeyboardShortcutSettings policy

Confidence: medium

Scope-risk: broad

Directive: Keep future terminal capture feeding SearchIndex documents through GlobalSearchCoordinator rather than adding another palette/navigation path

Tested: git diff --check; python3 -m json.tool Resources/Localizable.xcstrings; python3 -m json.tool web/data/cmux.schema.json; plutil -lint GhosttyTabs.xcodeproj/project.pbxproj

Not-tested: Local unit/UI tests and tagged app launch per task constraints

* Remove duplicate search refresh work

Cursor review pointed out that the menubar toggle and palette onAppear both refreshed the live index. Keeping the refresh in the palette lifecycle avoids resetting browser debounce tasks while still indexing each time the palette opens, and removing the unused workspace delete API keeps the storage surface honest.

Constraint: Review feedback came from PR #3908 after the first CI pass started

Rejected: Keep both refresh calls | causes avoidable debounce cancellation and slower browser result availability

Confidence: high

Scope-risk: narrow

Directive: Add workspace-level deletion only when a real workspace teardown caller is wired

* Inherit stdin in backgrounded ssh inside startup wrapper (#4135)

* Add regression test for SSH startup wrapper dropping stdin

After PR #3786 backgrounded the ssh invocation inside the startup
wrapper for signal/reconnect handling, `cmux ssh <host>` sessions
stopped forwarding keystrokes from the surface PTY to the remote
shell. Output flowed back (the remote prompt rendered in cmux UI),
but anything typed never reached zsh on the other side, which sat
blocked in `do_poll` on the remote pts.

Root cause: POSIX sh redirects stdin of an async command (`&`) to
/dev/null when job control is off — the default for the `/bin/sh -c …`
that runs the startup wrapper. Without an explicit `<&0` on the
`&`'d ssh line, the local PTY stdin is silently dropped.

This commit adds the failing regression test. The fix follows in
the next commit so CI can prove the test catches the bug.

* Inherit stdin in backgrounded ssh inside startup wrapper

PR #3786 wrapped the ssh invocation in `while :; do … & wait` to enable
SIGHUP/INT/TERM trap handling and reconnect-on-exit-255. Backgrounding
ssh, however, drops its stdin: POSIX sh redirects fd 0 of any async
command to /dev/null when job control is off, which is the default for
the `/bin/sh -c …` host that runs this wrapper.

As a result, output from the remote still flowed back to the surface
PTY (ssh's stdout/stderr stayed wired) but the user's keystrokes never
reached the remote — they hit ttysNNN on the Mac side, kernel echoed
them locally, but ssh's stdin was /dev/null so nothing was forwarded.
zsh on the far side sat in `do_poll` forever.

Explicit `<&0` on both the `command` line and the `( … )` shell-snippet
form overrides the POSIX default and re-attaches the wrapper's own
stdin to the backgrounded ssh process.

Verified with the regression test added in the previous commit, plus
manual repro on Darwin:

    /bin/sh -c 'cat &  wait'           # cat's fd 0 → /dev/null (bug)
    /bin/sh -c 'cat <&0 &  wait'       # cat's fd 0 → parent stdin (fix)

* Add docs search

Adds localized Pagefind docs search with heading anchors and section-aware results.

* Fix Swift interpolation escape in SSH stdin regression test (#4154)

`testSSHStartupForwardsStdinToBackgroundedSSH` used `\"<empty>\"` inside a
`\(...)` string interpolation. Swift parses `\"` as the end of the outer
literal, breaking compilation of cmuxTests on main:

    Cannot find ')' to match opening '(' in string interpolation
    Unterminated string literal

That kept `ci/circleci: macos-unit-tests` red on main after #4135 even
though `macos-debug-build` and `macos-release-build` still passed (the
test target was the only thing affected). The runtime fix (`<&0` on the
backgrounded ssh) is unchanged and was verified end-to-end on a cloud Mac.

Inside an interpolation, the string is already a Swift expression and
literal quotes are unescaped; drop the four backslashes.
