Adds Option+Z to toggle word wrap in the focused file editor, including editors in the Dock and Markdown text mode. The binding is configurable in Keyboard Shortcuts and shortcuts.bindings.toggleFileEditorWordWrap.

The View menu shows the current wrap state and disables the command outside an editor. Keyboard, menu, and the existing palette setting share fileEditor.wordWrap; open editors reflow in place without changing text storage, cursor/selection affinity, or undo history. The viewport origin is preserved within the new document bounds, so horizontal scrolling clamps when wrapping removes horizontal overflow.

Closes #12748.

Validation:

  • Focused hosted tests: all 7 executed and passed on the merged implementation, c4d21a6. The word-wrap implementation is unchanged since that run; subsequent commits document the APIs and merge upstream docs, CI, and tmux test-harness updates.
  • Coverage includes default/rebound/chorded/unbound shortcuts, configured when clauses, IME composition, app-level responder routing, selection affinity, viewport position, undo, resizing, document replacement, and palette persistence.
  • Swift file-length budget, project normalization, test target wiring (1,030 files), and Package.resolved policy pass.
  • Localization audit: both app labels and web shortcut text cover all 20 locales. Every web message catalog contains the updated docs key. Catalog parity and JSON validation pass.
  • Last completed tagged developer build, built using cmux-ci job db10415ba8b53c5fddcfd2e3 from exact SHA 647e7f274ee38271901960b1e61a9dce35c793b3. Artifact SHA-256: 7eb50e9ddc457b3be568231aabb9b7e8121e7413a54dc9f58343f0510cfd63f7. App name/bundle identity, artifact digest, publication read-back, and cleanup receipt verified; workspace reset completed. Submission, terminal, and publication receipts are saved under artifacts/fleet/ in the task checkout.
  • All three inline review findings have fixes and evidence replies; threads are resolved. The top-level internationalization and ambient-state findings passed CodeRabbit's subsequent review. The documentation warning is addressed in the final documentation-only follow-up; CodeRabbit's latest status is successful but rate-limited, so it has not rescanned that follow-up. Review evidence. Greptile reviewed the implementation and documentation follow-up with 5/5 confidence and no findings.

The current head is 80e72d8332691677a3f76d9f29412547394f40fd, including origin/main at d09eba334741dd4d6279d9261699bcd3066240b2. Current-head developer build: cmux-ci job 606fd67cb24aa98e31baf714; publication proof will be added when it finishes. The first build of the synced head failed because one worker retained a stale Iroh PCM; the failure was reported through cmux-ci feedback and the controller retry succeeded on a healthy worker. Both failed and successful receipts are retained. No local build or scheduling bypass was used.

Dogfood: open a wide source/JSON file, select text and make an edit, press Option+Z twice, resize the pane, check the View-menu state, and undo the edit. This PR remains unmerged pending user dogfood approval.

Mac fleet instructions for head 88de06bda45de132fad4bd3e393400f999c6987a. Planned tag: pr-12814-88de06bd; this is not yet a published build.

Use an existing campaign job ID if one is already posted; do not submit a duplicate. A wait timeout leaves the remote job running. Published results will include an exact-head artifact link and timing/disk receipt. This recipe validates the macOS app only, not iOS or tests. Never use maclease or put credentials in a PR comment.

Verified macOS fleet artifact for 88de06b: pr-12814-88de06bd. HQ restores/downloads this exact artifact on click.

Job 45ac3c712e20fca449d2862e. Active execution/cleanup: 728.8s; queue/setup: 3.2s. Free disk: 262.4 → 256.7 GiB. Workspace reset: True.

This proves a macOS app build and publication; it does not prove iOS, tests, or UI behavior. Fetch the durable receipt with cmux-ci wait 45ac3c712e20fca449d2862e --receipt artifacts/fleet/45ac3c712e20fca449d2862e.json. Do not resubmit this completed build. If the head changes, rebuild the new exact SHA.

Addressed every finding from the existing review through c4d21a68066325becbad5d3af73efe14ab29b009:

  • Source wiring: the production extension has a Panels/SavingTextView+WordWrapShortcut.swift path and belongs to the app target. The three inline threads now contain specific evidence and are resolved.
  • Internationalization: both app labels and the web shortcut description/note cover all 20 locales; every web message catalog contains the documentation key. The localization audit passes with zero parity errors.
  • Ambient state: FilePreviewWordWrapSettings is now a constructable struct with injected UserDefaults, instance reads/writes, and isolated test suites. Only immutable key/default catalog metadata remains static. Keyboard, menu, and palette use the same persisted preference.
  • Menu state: the View command is a checked SwiftUI Toggle, retains customization, and disables when no file editor owns the active responder.
  • Documentation: added contract comments to changed settings, initialization, responder lookup, layout, scope, menu, and behavior-test helpers in c4d21a6.

Merged origin/main at 52b99507c9f3b93fad0533aaee805d5700d3e104 without conflicts. The prior implementation had all PR checks green and all seven focused hosted tests passed: https://github.com/manaflow-ai/cmux/actions/runs/35417095819 . Current-head CI and a fresh focused run are in progress. Developer build job 587c50ca8840efbcf1ba9d6f uses cmux-ci with tag issue-12748-editor-wrap-shortcut; submission receipt is retained locally under artifacts/fleet/.

This is an evidence update, not merge approval. The PR remains open and unmerged.

RetriggerConfidence Score: 5/5

The PR appears safe to merge; no actionable correctness, security, localization, or repository-rule violations remain.

Summary

This PR adds a configurable Option-Z shortcut for toggling soft word wrapping in the focused file editor.

  • Routes the action through focused editor responders, including Dock editors and Markdown text mode.
  • Shares the persisted fileEditor.wordWrap preference across keyboard, View menu, and command-palette entry points.
  • Reflows open TextKit editors while preserving text, selection, undo state, and a constrained viewport origin.
  • Adds localized app and web documentation, shortcut metadata, schema support, project wiring, and focused tests.

Documentation follow-up: 0f75b320be6796d141c22552843842c29f7fe1de moves all seven behavior-test doc comments before their @Test attributes, and documents the affected configuration example, shortcut docs page, startup config test, scope projections, and detached-editor context. This addresses the remaining top-level documentation finding on c4d21a6; CodeRabbit's current status is successful but says Review rate limited, so its displayed 43.75% warning still belongs to the earlier revision and is not a new scan of this follow-up.

The merged implementation's focused hosted suite completed successfully: 7 tests executed and passed, https://github.com/manaflow-ai/cmux/actions/runs/35554586124 . The only changes since that tested commit are documentation. All three inline threads are resolved; the fresh Greptile review of c4d21a6 reported 5/5 and no findings. Current-head required CI is still running, and the final-SHA dev build is fleet job e34215b26fb0a1b3d2599208 with the requested issue-12748-editor-wrap-shortcut tag. No merge performed.

The remaining documentation warning is addressed in 647e7f274ee38271901960b1e61a9dce35c793b3: the touched app dispatcher, window/View commands, shortcut labels/defaults, Dock routing disposition, palette descriptor lookup/table, and editor convenience initializer now have contract comments. This follows the earlier placement fix for the test comments. File budgets still pass; no runtime behavior changed.

The latest implementation includes upstream 03e904d6f29849254e6bc5cabb10e166effac1ac and has no unresolved review threads. The superseded developer-build request was canceled while still queued; the new exact-SHA controller job is db10415ba8b53c5fddcfd2e3, using issue-12748-editor-wrap-shortcut. Waiting for the current-head CI and review results before closeout; no merge performed.

#12814 added a shortcut key to web/data/cmux.schema.json without running
scripts/generate-cmux-config-schema.py, so main's Fast static checks fail
with "CmuxConfigSchema.generated.swift is stale" and every PR merged with
main inherits the failure. The generator output is deterministic, so this
merges cleanly with an identical fix on main.

Cmd-Opt-= and Cmd-Opt-- must zoom the canvas when the focused panel is a
Markdown file in text mode. That editor is a SavingTextView but not a text
file preview, so the canvas layout clause should still allow canvas zoom.
Records the canvas zoom factors and checks the editor font is unchanged.

This test fails on the current branch: #12814 widened
filePreviewTextEditorFocused to every SavingTextView, which blocks
canvasLayoutOutsideFocusedContent (and Cmd-0, covered by
cmdZeroInCanvasResetsCanvasZoomWhenMarkdownSourceEditorIsFocused).

#7157 limited filePreviewTextEditorFocused to the focused text file
preview's editor, matching the command palette's
panelIsFilePreviewTextEditor, so Markdown source and Dock editors keep
Canvas zoom and do not take preview zoom. #12814 widened the flag to every
SavingTextView so word wrap works in those editors, which also turned off
canvasLayoutOutsideFocusedContent there: Cmd-0, Cmd-Opt-= and Cmd-Opt--
stopped reaching the canvas.

Keep both scopes. filePreviewTextEditorFocused is narrow again and drives
the shared shortcut context, preview zoom and Canvas routing. The new
fileEditorFocused covers every file editor and applies only to actions in
the .filePreviewTextEditor context (word wrap): whenClauseContext(for:)
projects it onto the file-editor atom for their `when` clause, both at the
keyDown gate and when arming chords, and isAvailable uses it for their menu
and palette state. FileEditorWordWrapShortcutTests.appShortcutRouting still
covers Opt-Z in a bare file editor.

approval_prompt_pending so a client learns that cmux stored the binding
without waiting on the user. Before the fix the key is absent because the
approval was collected inline by NSAlert.runModal() inside the command's
main-actor job, which starved every other main-actor job and wedged the
control socket. Fails on main; the fix lands in the next commit.

* fix(control-socket): never park a command on modal UI; bound and answer every socket lane (#13369)

A CLI-triggered surface.resume.set presented NSAlert.runModal() inside the
command's main-actor job. A nested modal run loop started from a main-queue
job does not drain the main dispatch queue, so every main-actor job in the
process starved: all socket main hops, the hang watchdog heartbeat, every
Task { @mainactor }. The connection pool filled (32 live + 64 pending = the
96 orphaned fds in the report), every further client was closed unanswered
(EPIPE), and worker-lane commands that hop through v2MainSync blocked
cooperative-pool threads, so nothing could recover.

Approval prompting gets one asynchronous owner:
- SurfaceResumeApprovalPrompter presents "Allow Resume Command?" as a window
  sheet, one proposal at a time, re-checking the record before each so one
  answer covers identical proposals. surface.resume.set stores the binding
  without auto-resume trust, queues the decision, and replies immediately
  with approval_prompt_pending. The context menu shares the same path. The
  isMainThread proxy in shouldPromptForProposal is gone.

Socket lanes are bounded and always answer:
- ControlBoundedHop runs main-actor hops with a 10 s deadline on an injected
  clock and a queued/running/withdrawn gate, so an abandoned body never runs
  late. v2MainAsync throws; one catch at dispatch replies with a structured
  timeout error carrying retryable.
- Legacy synchronous worker bodies run on a GCD lane instead of cooperative
  threads, so v2MainSync blocking cannot freeze the Swift runtime.
- ControlClientWorkerPool expires pending jobs older than the CLI's 15 s
  patience and tells drops why; ControlOverloadResponder reads the first
  line and writes a real overloaded error (with the request id) before
  closing. The CLI retries overloaded like rate_limited.
- Release telemetry: breadcrumbs per timeout/rejection, one captured
  warning per stall episode, and an accept-buffer-drop breadcrumb.

* fix(control-socket): public Dispatch import for the pool's default clock argument

A public initializer's default argument is emitted into clients, so the
DispatchTime expression needs the module imported publicly, matching
ControlClientRateLimiter. Also drop the unused Dispatch import from the
overload responder.

* fix(control-socket): cover every queued approval, answer accept-buffer drops, size the reply bound

Review follow-ups on #13397:
- A record written while identical proposals were queued now applies to
  every surface it covers (resolve returns .covered(record)), instead of
  only the surface whose sheet was shown.
- The accept path hands buffer-full connections to the host through a new
  SocketControlServerEvents.connectionDropped hook; the app routes them to
  the overload responder (reason accept_buffer_full) so the client gets a
  structured error rather than EPIPE.
- The responder's concurrent-reply bound is derived from the pool sizes
  (live + pending + preauthorization claims + headroom = 256) so a batch
  expiry cannot push concurrent rejections back to a bare close.

* build: wire the new socket-lane and approval-prompter sources into the app target

The app target lists sources explicitly, so the five new Sources files were
never compiled and every symbol they define was reported missing. Also await
the body-started signal in ControlBoundedHopTests instead of blocking on a
semaphore from an async context.

* test(control-socket): stop racing the Web Inspector readiness deadline against task yields

The readiness window is only a safety bound; markOperationReady() wakes the
waiter through the condition broadcast. A 1 s window raced 100 task yields
against real time and failed twice in a row on loaded runners.

* fix(control-socket): precise error mapping for legacy bridges and committed team mutations; signal-driven responder tests

Review follow-ups on #13397:
- The synchronous lane's system.top/system.memory bridges mapped every error
  to a main-actor timeout via try?. socketLegacyMainHopBridge now maps only
  SocketMainActorHopTimeout (with its real retryable flag); cancellation and
  other errors keep their identity.
- v2AuthTeamMutationAsync gives the mutation and the post-mutation status
  read separate error boundaries. A status-read timeout after a committed
  team change returns a non-retryable timeout with committed: true instead
  of team_selection_failed, so a retry cannot create a duplicate team.
- ControlOverloadResponderTests await the rejection callback through an
  AsyncStream instead of counting task yields.

* test(control-socket): assert the observed EOF with a generous bound in the responder tests

The 5 s wall-clock bound raced libdispatch's utility-queue cancellation
handlers on a loaded runner; the poll still returns the instant the peer
closes, and the test now asserts that EOF was actually observed instead of
a second zero-timeout poll.

* Regenerate embedded cmux.json schema after #12814

#12814 added a shortcut key to web/data/cmux.schema.json without running
scripts/generate-cmux-config-schema.py, so main's Fast static checks fail
with "CmuxConfigSchema.generated.swift is stale" and every PR merged with
main inherits the failure. The generator output is deterministic, so this
merges cleanly with an identical fix on main.

* Report read errors as not-EOF in the overload responder test helper

A read error such as ECONNRESET is an abrupt disconnect, not the clean
close the responder promises, so readUntilEOF now returns sawEOF: false
for it and the tests fail if the responder resets instead of closing.

* Localize the legacy bridge's cancelled and request_error messages

The socketLegacyMainHopBridge error mapping added in this PR returned two

entries for the nine supported macOS locales.

* test: pin that the socket focus policy follows the command task across threads

withSocketCommandPolicyAsync keeps the focus decision in thread-local storage across an await. A command that resumes on another thread before its lane hop then loses the decision, and the lane runs with the default policy. Two dedicated-thread executors make that resumption deterministic, so this test is red until the decision is bound to the task.

* Bind the socket focus policy to the command task

withSocketCommandPolicyAsync pushed the focus decision onto a thread-local stack and popped it after an await. A command task can resume on another thread, so a later lane hop captured that thread's stack instead: the main actor or the worker then ran with the default policy, and the original thread kept a stale entry. The decision is now a task-local bound for the scope of the command, and each lane hop copies it into the thread-local stack only for its synchronous body.

* docs: relay-backed requests do not retry overloaded replies

sendV2 only retries an overloaded reply on a direct control-socket request; the relay path surfaces it. Say so in the client-behavior column.

* test: keep socket and receipt waits off the main thread and cooperative pool

swift-package-tests hung for about 5 s per test on the 6-vCPU macOS runner
and then failed with "Unable to parse empty data". The accept-buffer drop
test polled its socket synchronously on the main actor. Main-owned fakes
elsewhere in the run call DispatchQueue.main.sync from pool threads, so
they parked the cooperative pool, and the overload responder's reply task
could not run until the poll gave up.

- UnixSocketFixture.readUntilEOF now waits on a GCD thread and reports
  whether it saw EOF, so no test blocks the main actor or a pool thread.
- The drop and responder tests await that reader. Clients that write
  before the responder reads get a 30 s read deadline, so a starved runner
  cannot turn a correct reply into a bare close.
- ControlBoundedHopTests wait on async streams instead of spinning on
  Task.yield().
- The Web Inspector receipt test waits on a GCD thread. Under a one-thread
  pool (LIBDISPATCH_COOPERATIVE_POOL_STRICT=1) its detached wait held the
  only pool thread for the 60 s readiness bound and pushed the responder
  and server suites past their time limits.

* fix(control-socket): make the overload responder's Foundation import internal

The responder exposes no Foundation types in its public API, so the public
import produced a "public import of 'Foundation' was not used in public
declarations or inlinable code" warning.

* test: wait on the Web Inspector waiter's entry signal instead of sleeping

The readiness-deadline test slept before asserting that the receipt had
not cancelled early, which the test-determinism guard rejects as
sleep-then-assert. The waiter now runs on a GCD thread (never the
cooperative pool), signals through an AsyncStream as it enters wait(),
and the test drains the executor with a fixed number of yields before
the assertion. A 60 s readiness bound keeps a slow runner from reaching
the deadline, while markOperationReady() wakes the waiter immediately.

Disabling the readiness branch in the receipt still fails the test at
the cancellation expectation.

* Match the CMUX_NO_GIT_WATCH contract to bash without a PR poller

#15074 pinned bash to stopping _CMUX_PR_POLL_PID and deleting the per-panel
PR cache files at the opt-out prompt. #15075, merged minutes later, removed
bash's PR poller and deliberately leaves old cache files alone, so
tests/test_shell_no_git_watch.py fails with Apple bash 3.2 on main.

The PR-poll and cache checks now run for zsh only, which still has both;
bash is still held to stopping its tracked Git job and every other opt-out
behavior. docs/shell-integration.md says the same.
