Draw resting sidebar rows lighter and give workspace titles their room back

[teamleaderleo]

Summary

Two complaints about the same list, fixed together: the sidebar was all semibold, and workspace titles ran out of room long before they ran out of name.

Weight. Every workspace title was semibold, so the list had no spare emphasis left for the rows that matter. A selected row and a row with unread notifications looked exactly as heavy as the twenty quiet rows around them. Resting titles now draw at regular weight. The selected row (including a row that joined a multi-selection) and any row with unread notifications keep semibold, so both states still read at a glance. Group header names step down from semibold to medium, which keeps them distinct from the member rows below without shouting.

The sidebar has two renderers, the AppKit table cells and the SwiftUI rows, and each used to hardcode the weight on its own. Both now resolve it through one shared SidebarRowTextWeight in CmuxSidebar, so a row cannot look different depending on which one drew it. Two details follow: the inline rename field takes the weight of the title it replaces, so text does not jump when you start renaming, and the group header's height measurement uses the same font it draws with.

Room. Three defaults were spending horizontal space a title could have used: a 12.5pt title size, 10pt of content padding on each side, and a trailing column held open for a close button that only appears on hover. The title now draws at 12pt, content padding is 8pt, and a resting row spends the close button's column on its title until the button actually shows. A wrapped title keeps the reservation, because hovering must not change a row's height. One-line titles truncate in the middle instead of at the end, so a name like cmux-remote-status @workstation keeps both its start and the host that tells it apart from its siblings.

sidebar.twoLineWorkspaceTitles (off by default) is a middle ground between one line and the existing sidebar.wrapWorkspaceTitles: long titles get a second line, short ones keep their height. It is the only user-facing string this PR adds: its Settings label, its subtitle and its search alias are in the catalog in all nine languages, and the schema and cmux.json accept the key.

Badges, links, buttons and the small secondary lines keep the weights they had. Those are 8 to 10 point, where semibold is legibility rather than emphasis.

How much this buys, and why the default width does not move

Title width at the 240pt default goes from 172pt to 212pt. Measured with the same text layout the rows use, these are the characters of each title that fit on the title line, before and after:

Title	Before	After
Fix cmux pane focus indicator flicker	31	37
cmux-remote-status @workstation	27	31
Docs pass over the sidebar row copy	30	35
Sidebar title truncation	24	24
feat/workspace-group-collapse	28	29

The obvious alternative was to widen the default sidebar. These numbers are the argument against it. Nothing here lands anywhere near the dozen characters the complaint described, and the one title that gains nothing is 24 characters long, so it already fitted end to end and has nothing left to gain. A wider default would cost every user horizontal space in the surface they actually work in, to fix a problem that the padding, the point size and the close column had already been causing on their own.

SidebarWorkspaceTitleRoomTests keeps these numbers honest: it reads the current geometry from the shipping sources, requires that no title loses room, that a title which was being cut off gains strictly, that a title which fitted whole still fits whole, and that every title clears 20 characters.

Those four clauses replaced a single one, "every title shows strictly more than before", which the first measurement run failed on the 24 character title. The failure was the assertion asking for room that cannot exist, not the change giving less; the replacement pins down more of the property than the original claim did, rather than relaxing it to fit the code.

Before and after

Both frames come from the same dogfood tour, at the same window size and the same default sidebar width: ten workspaces, one selected row, one unread row and a group.

The pair below was captured from commit ad8b0f3696d, not from the current head. The branch has taken main merges since, including #14838's compact status glyph, and a grep of that delta for this change's own symbols (SidebarRowTitleMetrics, SidebarRowTextWeight, twoLineWorkspaceTitles, titleLineLimit) returns 16 lines in Sources/ContentView.swift and Sources/Sidebar/AppKitList/Cells/SidebarWorkspaceRowCellView.swift, which are the paths these frames render. So they do not carry on that test, and the tour is being run again on the current head; the images above update in place when it finishes. The claim they support, that resting rows are lighter and long titles keep their tails, is unchanged, but treat them as the earlier commit's evidence until the new run lands.

Before (main)	After

The sidebar alone, from the same tour run at 200 percent font magnification so the stroke weight and the truncation point are both legible. On the left every row is semibold and the long titles lose their tails. On the right only the selected row and the unread row are semibold, and the titles that have to truncate keep both their start and their end, so cmux-remote-status @workstation still shows the host. A CJK title and an emoji title are in the list as well, since a change to title measurement should be looked at with both.

Before (main)	After

Testing

Added:

• CmuxSidebarTests/SidebarRowTextWeightTests covers the weight decision and pins the AppKit and SwiftUI mappings to each other, which is what stops the two renderers from drifting apart again.
• SidebarAppKitRowCellTests.workspaceTitleWeightTracksSelectionAndUnread configures a row cell and reads the font off its title view for resting, selected, multi-selected and unread rows.
• SidebarWorkspaceTitleRoomTests measures the table above and pins the close column's 24pt to the resting row.

Executed: the focused runs linked in the comments, plus the two dogfood tours that produced the frames above (one on the branch at ad8b0f3696d, one on main, same scenario), with a fresh pair running on the current head.

String catalog merges

This branch adds catalog keys, so every merge from main runs through the repository's .xcstrings merge driver. After the latest merge the audit says the driver did its job: the merged key set is exactly the union of both sides, 7195 keys from parents of 7194 and 7192, with nothing missing and nothing invented. No key lost a locale it had on either side, and the four keys this PR adds are present in all nine languages. localization_catalog.py check reports no parity errors, and the embedded config schema check passes.

Summary by cubic

Draws resting sidebar workspace titles at regular weight so selected and unread rows stand out, and gives titles more room at the default sidebar width.

• Selected, multi-selected, and unread rows keep semibold; group headers drop from semibold to medium. Both renderers resolve weight and title metrics through shared SidebarRowTextWeight and SidebarRowTitleMetrics.
• Titles draw at 12pt instead of 12.5pt, content padding drops from 10pt to 8pt, and resting rows no longer reserve the hover-only close button's column. One-line titles truncate in the middle, keeping their tail; the shortcut hint pill still holds the trailing column open.
• Adds sidebar.twoLineWorkspaceTitles (off by default) as a middle ground between one line and sidebar.wrapWorkspaceTitles; wrapping outranks it. The key is localized in all nine languages and wired into the config schema, settings search, and cmux.json.
• The rename field matches the weight of the title it replaces, and the selection preview paints colors without flipping weight, so a row is never drawn at a weight its frame was not measured for.
• The dogfood tour builds resting, selected, unread, and group-header rows side by side with truncating titles and pins its row settings to the shipping defaults.

^{Written for commit a844a96. Summary will update on new commits.}

Summary by CodeRabbit

• New Features
  • Added a sidebar setting to let workspace titles wrap onto two lines before truncation. This option is unavailable when full title wrapping is enabled.
• Visual Improvements
  • Workspace titles use regular weight when unselected with no unread notifications, and semibold when selected, multi-selected, or showing unread notifications. The same weight is used while renaming.
  • Group header names use medium weight for a lighter appearance.
  • Single-line titles can use more space when the close button is hidden, and sidebar title truncation adapts to the selected line limit.

Full details: Docstring Coverage

Explanation

Docstring coverage is 54.76% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 42 functions across 22 files. (4 skipped: 3 unsupported, 1 too large.)

Full details: Cmux Full Internationalization

Explanation

The PR adds production copy without complete localization. Resources/Localizable.xcstrings supports 20 locale codes, but both settings.app.twoLineWorkspaceTitles and settings.app.twoLineWorkspaceTitles.subtitle contain only 9 entries. The missing locales are bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and uk. The new web/data/cmux.schema.json property also adds an English description without a locale-specific source. The configuration documentation renders property.description directly when descriptionKey is absent, so this copy appears on localized web pages without matching web/messages entries.

Resolution

Add translated catalog entries for all 11 missing app locales for both new setting keys. Change the schema property to use a localized descriptionKey such as schemaDescriptions.sidebar.twoLineWorkspaceTitles, add translated values for that key to every locale in web/i18n/routing.ts, and update Packages/macOS/CmuxFoundation/Sources/CmuxFoundation/ConfigValidation/CmuxConfigSchema.generated.swift to remain synchronized with web/data/cmux.schema.json.

Dogfood build of a844a962b7df1db295de8bf9c1b1d6dacf0d9eae

cmux DEV pr-15229-a844a962.app

The link opens this exact commit in the cmux dev menu bar app; the page waits until the build is ready. Builds run only while this PR has the dev-build label. Under load the fleet builds the newest push each time a worker frees up, so some pushes are skipped. It signs in against production, so Cloud or backend changes still need a tagged build with a development backend.

Covers 4fdba681..a844a962 (commits: 32) since the previous link, cmux DEV pr-15229-4fdba681.app; if that push was skipped, its page names the newer build. To build a commit in between: cmux-ci build cmux --ref <sha> --tag bisect-<sha8> --workspace https://github.com/manaflow-ai/cmux/pull/15229.

Reviewed with a subagent before merge. Findings and what happened to each.

Fixed in 4366c25

1. Row heights are measured from the stored model, but the title height came from titleView.measuredHeight(width:), which reads whatever font the last apply installed. Keying the title weight off selection made that font depend on the optimistically painted copy of the model, so a wrapped title could be drawn at one weight inside a frame measured at the other, and refreshVisiblePumpHeightOverrides could record the mis-measured height and keep it after the paint reverted. The title font now resolves from the stored model even while a painted copy supplies the colors. Selection colors still flip on press; the weight follows the authoritative apply. Covered by optimisticSelectionPaintDoesNotChangeTitleWeight.
2. The inline rename field took its font once, when renaming started. A notification arriving mid-rename would have left it one weight behind the row it sits in. It now tracks the title font on every apply.

Checked and not a problem

3. The review read workspace.create and workspace.group.create as taking created_workspace_id / title and as ignoring child_workspace_ids. Those are the mobile host handlers. On the control socket these methods are served by ControlCommandCoordinator, which takes name and child_workspace_ids and returns workspace_id and a group object. The dogfood run confirms it: every socket step in the tour returned ok, the group came back with three members, and the frames show the grouped rows and the unread row.

Clean, no work needed

Weight coverage in both renderers, global font magnification at every call site, the group header's measure and apply using one font, isActive / isMultiSelected / unreadCount participating in hasHeightEquivalentContent so a weight flip re-measures, Swift 6 and package correctness for the new type, and the added tests. The behavioral test fails on the base commit, which is what makes it a regression test.

Left alone

Cloud machine rows in Sources/Cloud/ draw their names at semibold or medium and will now read heavier than resting workspace rows. Different rows in a different section, and not a disagreement between the two renderers, so it is out of scope here.

Review

A correctness-first review pass over this diff, plus the checks on the head before it, turned up four things. All four are fixed on 896422c.

Fixed

1. The shortcut hint pill could sit on top of the title. Reserving the trailing column only while the close button or a status badge shows was not enough: the close button is deliberately hidden while shortcut hints are up, and the pill is an absolute overlay rather than an occupant of that column, so nothing held the space open. With the title now running further right and truncating in its middle, the tail it overlapped was the distinctive part. The row now treats a visible hint pill, and any title on more than one line, as holding the column open. The reservation is the constant close-button width rather than the pill's own variable width, so neither hover nor a held modifier can change a row's height. Covered by shortcutHintPillHoldsTheTrailingColumnOpen, which checks the title box before and during hover and that the close button stays hidden.

2. The two new setting strings were in the wrong catalog. All three call sites read them through a bare String(localized:), which resolves against the app bundle, so the entries had to live in the app catalog rather than the settings package one. The third call site, in the settings search index, is what makes this visible as a missing string rather than a fallback. Both keys moved with all nine required locales; catalog parity reports no errors.

3. SidebarRowTitleMetrics was an all-static type, which the package conventions check rejects. It is now a value type built from the line limit, with the truncation modes derived from it, so a title laid out on one line cannot be truncated at its end in one renderer and in its middle in the other. Both renderers construct it the same way.

4. sidebar.twoLineWorkspaceTitles had no settings anchor path, so the curated settings entry was unreachable and the package test that guards that contract failed. Its path is now in the contract list.

Left

Nothing outstanding from the review. It came back clean on the parts that matter most here: the measured font and the drawn font cannot diverge, row model equality covers every input that can change a measured height, hover cannot change a row's height, the weight choice for an optimistically selected row is deliberate, the setting is plumbed through every place a setting has to appear, and the code stays Swift 6.0 compatible.

Measured title room on this head

Leading characters visible on the title line at the default sidebar width, before and after this PR:

title	before	after
Fix cmux pane focus indicator flicker	31	37
cmux-remote-status @workstation	27	31
Docs pass over the sidebar row copy	30	35
Sidebar title truncation	24	24
feat/workspace-group-collapse	28	29

The fourth title already fitted, so it is unchanged. Source: SidebarWorkspaceTitleRoomTests, run at 240pt.

Landing receipt for head 3bf7ffa2720ce3955310b641c9d350b8df1707ab.

• Merged the latest origin/main without rebasing or force-pushing. The pinned-defaults commit d8bc6e08b452240811be53b64e46fcf156ab1368 remains in history. It explicitly pins the sidebar tour's row settings because resetDefaults does not clear settings left by earlier fleet runs, so the "default" frames now exercise the shipping defaults.
• Catalog union audit at this head: merge base efb762c914e7a07d33a300650b192d9acbd71017 = 7,385 keys, branch parent 3d9a2f4b6dc20092d55805f03f1ff84f798bb4e3 = 7,388, main parent 64ec56d4cf967ba00c09b3e6b55dd79b1f86b1dd = 7,388, merged file = 7,391. Exact union = 7,391, missing = 0, invented = 0, both-sides-changed = 0, main-deleted-resurrected = 0, duplicate literal JSON keys = 0. Main values and branch-only values are preserved.
• The old macos / app-host unit tests (7/7) red was diagnosed from its xcresult: PaneResizeShortcutTests.configuredShortcutAndRepeatMoveDivider(direction:) failed because newTerminalSplit returned nil with noSpace for left/right. It was an inherited stale-size test assertion, not sidebar product behavior. The current main fix from ce5cb45 gives split tests a realistic window before splitting; no sidebar product change was needed for this failure.
• The extra old-shard failure, SurfacePaneFactoryFocusTests.focusedSplitFocusesTheNewPane(), also returned .creationFailed("noSpace") and is likewise outside this PR's changed paths.
• Local evidence: localization catalog check, project normalization, python3 scripts/verify-local.py, diff check, and all portable checks passed. The Linux guard sweep passed 73/75 steps; the two reds are inherited workflow guard tests (test_branch_lookup_failure_still_dispatches and test_the_dispatch_step_waits_until_its_run_is_listed) in current main guard infrastructure, not files changed by this PR. No local app build was run per the wave rule.
• Correctness review found no concrete findings. Review coverage included shared typography metrics, both sidebar renderers, truncation/height behavior, shortcut-pill reservation, setting wiring, localization, and regression tests.
• Current GitHub rollup at this head: MERGEABLE (BLOCKED), 72 passed, 0 failed, 4 pending of 76; pending are ci-status plus Claude wrapper regressions, macos / swift-package-tests, macos / macOS compile admission, and ui-tests. The earlier package red at the previous head was an unchanged CmuxRemoteDaemon timeout-isolation test waiting for child termination; the earlier Claude wrapper cancellation hit its 15-minute job limit. Neither is a current red at this final head.

Human action: wait for the four pending checks, then maintainer review/merge when ci-status is green. Do not enable auto-merge based on this receipt.

Triage for run 36695241162 on 3bf7ffa272, so nobody chases the wrong thing:

• ui-tests reads as cancelled in the checks list, but its annotations say The job has exceeded the maximum execution time of 15m0s followed by The operation was canceled. That is a timeout, not a cancellation and not a test failure.
• swift-package-tests is timedOutPTYAttachBoundsCancellationWrite(). main passed the same job in the same window (job 109825899736) and test: hold the daemon writer before the PTY attach deadline handler runs #15921 fixes it at the root, so it is a flake here.
• Nine jobs are still queued, including the app-host shards. Those are likely to fail on something this branch did not cause: main does not currently compile, because 7d246ed4e5a (fix: open existing Cloud workspace rows optimistically #15747) reverted the vendor/bonsplit gitlink to a commit that predates BonsplitContrastPalette and TabPresence, both of which main's Sources/ uses. PR CI builds the merge ref, so the break reaches this branch. fix: restore the bonsplit pin main's sizing code needs #15930 restores the pin.

Holding reruns until #15930 lands and catch-up brings this branch onto a compiling main, since that produces a fresh run and makes any rerun now wasted work.

Evidence requirement changed, and this PR is no longer waiting on a fleet dogfood

Leo's standing rule as of today: the fleet dogfood queue is not being processed, so nothing should wait on it. I have withdrawn the queued request for this PR.

For a UI fix like this one the evidence is now a regression test plus the CI dogfood tour screenshots, which pr-media.yml posts to this PR by itself after a CI attempt completes. No manual fleet run, and the dev-build label is not needed for the tours (it only adds the dev build link).

One honest caveat about why the screenshots are not here yet, which is not this change: the tours run with --adopt-only, so they load the app that CI compiled rather than compiling their own. main currently does not compile, because #15747 reverted the vendor/bonsplit pin to a commit predating BonsplitContrastPalette and TabPresence. Until that is fixed there is no app build for a tour to adopt.

#15930 fixes it and its macOS compile admission has already passed. Once it lands I will catch this branch up, let CI compile, and the media comment should follow. If a tour posts a skip note instead, it can be forced with gh workflow run pr-media.yml -f pr=<n> -f force=true.

Then this merges on green, since fixes do not go to team review.

CI handoff for head 4343d4a1c848300a4597457b2891f5e0c1b135e5 (run 36711890599):

• PR state: OPEN, MERGEABLE (BLOCKED). Squash auto-merge remains enabled.
• Rollup: 82 passed, 10 failed, 0 pending of 92 checks; ci-status is red.
• Root reds: macos / app-host unit tests (1/7) through (7/7). The logs show test assertions and 60/300-second test timeouts in unrelated CLI, SSH, Cloud workspace, placement, and adoption suites. The jobs completed normally on their assigned runners; no glaeda-cmux-runner-hook disk refusal, runner setup loss, or runner disconnect was observed. These are not attributable to the sidebar changes, but they are also not eligible for the requested infrastructure-only rerun.
• Downstream reds: macos / macOS status (reports the app-host unit-test failure), tests (macOS workflow did not pass), and ci-status (aggregate failure).
• macOS compile admission, Swift package tests, UI tests, web checks, guards, and other non-app-host lanes passed.
• No job was rerun. No files, commits, rebases, or force-pushes were made after the catch-up push.
• No current-head pr-media comment or tour skip note is present yet, so no manual media dispatch was triggered.

Human action: resolve or explicitly rerun the unrelated app-host test failures when appropriate, and obtain the CI tour media comment required for this UI fix. Auto-merge can proceed only after the required checks are green.

Catch-up merge pushed: 8d6749c55b

This pull request had gone to CONFLICTING against its base, which stops CI from running at
all, so no check could report and the auto-merge that was already enabled could not fire.
origin/main merged into feat/sidebar-lighter-text-weight cleanly, with no conflicted paths.
The merge combined the localization catalog, the generated config schema, the web schema, the
Xcode project, Sources/ContentView.swift, the two sidebar row cell views and
cmuxTests/SidebarAppKitRowCellTests.swift, and git resolved every one of them.

Guards run locally on the merge result, all passing:

guard	result
tests/test_localizable_xcstrings_structure.py (the duplicate-key assertion)	OK, 3 tests
scripts/lint-xcstrings.py	passed, 23 catalogs
scripts/lint-pbxproj-test-wiring.sh	ok, 1172 Swift files
scripts/normalize-pbxproj.py	no change, already normalized
tests/test_ci_test_execution_registry.py	OK, 32 tests
tests/test_cmux_schema_parity.py	OK, 7 tests
tests/test_cmux_config_schema_embed.py	OK, 5 tests
tests/test_cmux_settings_supported_paths.py	OK, 8 tests

Two things are worth calling out about this particular merge.

The catalog guard matters because the merge combined Resources/Localizable.xcstrings from
both sides, and that is the file where a merge produces duplicate keys that only CI sees.
Merging main in locally runs the repository's merge=xcstrings-v2 driver, which deduplicates,
and the structure test confirms the result.

The settings observation lists needed a check, because a syntax-only parse cannot catch a
merge that drops a declaration an observation list still names. None of the files this merge
combined contain a startSettingsObservation call, so there was nothing for the merge to
break there.

CI now has main as an ancestor, so its merge ref has nothing left to combine, and the
enabled auto-merge can act once the required checks report.

The red swift-package-tests is routing, not this branch

The one failing check on 8d6749c55b never ran a Swift package test. The job failed at step 10, Select helper Xcode, and skipped steps 11 through 23 including Run Swift package tests.

It landed on glaeda-std-xcode-26.6. Under full-ci the job first builds the Release Ghostty CLI helper against an SDK 15 Xcode, which only the Blacksmith macOS 15 image carries. The minis have Xcode 26.6 alone, and select-ci-xcode.sh exits non-zero rather than falling back, exactly as ci-macos.yml documents for this job.

The lane is supposed to take an owned Mac only when the run builds no helper. pr_runner_pool.package_lane_owned() still says so, but production stopped reading it: #15988 moved selection to simple_pool_picker.py, which places the lane on the routing flag alone. Fix is up as #16110, with a test that fails against the current picker.

Two consequences for this pull request:

1. Re-running the job by hand does not help. runs-on keeps the owned pool while run_attempt <= 2 || triggering_actor != 'github-actions[bot]', so a manual re-run at any attempt takes the same machine and fails the same way.
2. The picker code comes from this branch's merge ref, so this pull request needs a catch-up merge after fix(ci): keep swift-package-tests off the owned minis under a Release helper #16110 lands, not just a re-run.

Nothing here is attributable to the sidebar text weight change. Auto-merge stays on; I will merge main in once #16110 is on it, and batch that with any other change so it costs one compile.

Bugbot is paused — on-demand spend limit reached

[teamleaderleo]

Pushed a catch-up merge, 5a2242cbfe3, so this branch picks up the pool picker fix that
explains its earlier red.

The previous catch-up here took 2eb9bee950e (#15988), which is the commit that introduced
the routing defect: simple_pool_picker.py placed the swift-package lane on an owned mini
even on a full suite Release run, where no Xcode carries the macOS SDK 15, so
Select helper Xcode exited non-zero and the job skipped Run Swift package tests
entirely. That is why the red named a Swift package test that never ran.

The fix is #16110, merged as cc302537b37. Because a pull request reads CI scripts from its
own merge ref, the fix only reaches this branch through a merge, which is what this push is.
I took main's tip rather than the newest green commit on purpose: the tip differs from that
green commit only by the CI script fix itself, and the fix is the reason for the merge. The
picker's tests pass on this branch.

Auto-merge stays on. Nothing in the branch's own diff changed.

[teamleaderleo]

Pushed a catch-up merge to main's tip. Worth recording why, because the symptom is easy
to misread as "CI is slow".

This pull request was reporting mergeable=CONFLICTING, mergeStateStatus=DIRTY, and a
DIRTY pull request runs no CI at all. What it showed instead was a small number of checks
with the required ones simply absent, which reads like a queue rather than a stop. #16048
made that unmistakable: 8 checks, none failed, none pending, and ci-status plus
web-validation never reported.

The conflict was not in the content. git merge-tree --write-tree HEAD origin/main against
the exact tip exited 0 and produced a tree, on this branch and on two others reporting the
same state at the same moment. The one difference worth noting is the vendor/bonsplit
gitlink: these branches carried bd340add907, which was main's pin when they last caught
up, while main had moved to b4fc5e29b4f in #15613. That is a one-sided change, so it
merges cleanly, which is what the local test confirms.

So I am not claiming the gitlink caused it. What is verified is the sequence: three branches
reported DIRTY while merging cleanly against the tip, and a catch-up merge to the tip plus a
push cleared all three to MERGEABLE. The practical rule is to check the merge locally
before believing the label, and to push rather than wait, because waiting produces no CI and
looks like waiting for CI.

New head here, with the vendor/bonsplit pin now matching main. The branch's own diff and
its setting default are unchanged.

[github-actions]

CI fast guards failed on a844a962b7 (https://github.com/manaflow-ai/cmux/actions/runs/36764249190). It does not block the merge; a red guard merged into main breaks it for every open PR.

Run canonical CMUX CI guard profile (red on main too, not this PR)

Main has failed this step since #16150 by @teamleaderleo (self-merged) (#16162). Merge main again once the fix lands there.

Agents: python3 scripts/ci/guard_attribution.py fix applies the mechanical fixes locally. This comment is updated in place on each push.
