Right sidebar overhaul

[lawrencecchen]

Combines the right sidebar work into one branch and one dogfood tag (sbx). Supersedes #12710 and #15517, and includes #15526.

Dependency

vendor/bonsplit points at manaflow-ai/bonsplit#264 (head 807bf5f, based on bonsplit main). It combines bonsplit 242 (host focus input) and 262 (trailing tab bar inset). Merge bonsplit 264 first, then point the submodule at the merged main SHA before merging this PR.

Focus

When the right sidebar owns input, the selected mode icon in the sidebar mode bar takes the cmux accent, and the focused main Bonsplit tab loses its emphasis (BonsplitView(isMainContentFocused:)). No border, padding or clip is added, so layout is identical in both states. This mirrors how the Bonsplit selected tab shows focus.

One source of truth: MainWindowFocusController.intent (per window) publishes FileExplorerState.rightSidebarOwnsInputFocus. The mode icon tint, the Bonsplit tab emphasis and the panel focus ring all read it through WorkspacePanelVisibilityPolicy.mainContentIsFocused. Hiding the sidebar by any path releases sidebar focus through the isVisible handler, so no stale cue stays. Like the Bonsplit tab emphasis, the cue follows the window's own focus owner and does not dim when another window is key.

Toggle button

The right sidebar (⌘⌥B) had no button that stays on screen while it is hidden, so it could only be reopened by shortcut, menu or palette. This adds rightSidebar.toggleButton in cmux.json, which picks where a persistent show/hide button lives, so we can dogfood placements and keep the best one:

• titlebar (default): the window's top-right corner. While the sidebar is shown, the mode bar close button sits at that exact position and takes the same sidebar glyph, so toggling never moves the button. Works in standard, minimal and fullscreen windows.
• paneTabBar: the end of the top-right pane's tab bar, after the split buttons. It follows that pane's edge when the sidebar opens.
• sidebarFooter: the trailing end of the left sidebar footer. Hidden while the left sidebar is hidden.
• hidden: no persistent button; the close button and shortcut still work.

A thin hover edge handle on the window's right edge was evaluated and left out. Terminal portals draw above SwiftUI, so an edge overlay is covered by the terminal unless it is an AppKit view reordered above every portal host, and it would sit on the window resize edge and the terminal scrollbar.

The button is per window: it resolves its own window and calls the same toggleRightSidebarInActiveMainWindow path as ⌘⌥B. Its tooltip shows the shortcut. The command palette has Right Sidebar Button: <placement> commands, and the Debug menu has a Right Sidebar Button picker, both switching every window live.

Minimal mode and paneTabBar need the top-right tab bar to leave room at its end. That comes from Bonsplit's new Appearance.tabBarTrailingInset (now in manaflow-ai/bonsplit#264), which mirrors the traffic-light leading inset.

The settings path follows the typed catalog: RightSidebarCatalogSection + RightSidebarToggleButtonPlacement, parser, supported paths, template, schema (the rightSidebar object stays open for legacy and extension keys), generated schema, configuration docs, all 20 web locales and the settings skill reference.

Credit: @austinpower1258's #10366 supplied the SidebarGlyph extraction, RightSidebarOpenAsPaneButton and ResolvedSettingsSnapshot moves (co-authored). #5988 by @lidge-jun (AppKit trailing titlebar accessory) and #11913 (a button in the left titlebar control cluster) were read as prior art. A titlebar accessory is hidden in fullscreen and minimal mode, so this PR draws the corner button in the window content instead. The left-cluster placement was not kept because main deliberately removed a right-sidebar toggle from the global titlebar (BonsplitTabDragUITests asserts titlebarControl.toggleRightSidebar is absent).

Toggle testing from #15517:

• cmuxTests/RightSidebarToggleButtonTests added (layout rules for every placement and mode, cmux.json parse with extension keys kept, unknown value rejected, palette writes, supported path and template). Not executed yet; will run on the fleet.
• Bonsplit swift test --filter TopTrailingPaneTests: 4 passed locally.
• python3 scripts/verify-local.py --affected origin/main --swift-changed origin/main: 16/16 passed (localization parity, project wiring, schema embed).
• Fleet build job 4a34c812ac9860b702000586 (commit e1b125a, tag sbtog) succeeded. Launched locally and captured socket screenshots: titlebar hidden/shown in standard and minimal mode (corner button and close button share one position), paneTabBar standard hidden/shown and minimal, sidebarFooter standard. Placements were set with defaults write before each launch; live switching through the palette and Debug menu was not clicked.
• Known cosmetic gap: the reserved tab bar inset does not draw the tab bar's bottom separator line under the button.
• Unverified: fullscreen, multi-window independence, palette and Debug menu live switching, click hit-testing in the minimal-mode titlebar region.

Localization audit: 12 new macOS keys with all nine catalog locales via scripts/localize-changes (0 parity errors); 3 new web message keys in all 20 locales.

Files rewrite

Merged from #15526 (head c6b8bdf2511).

The right sidebar Files tree hung the main thread on any large folder. FileExplorerNode.sortedChildren re-sorted a folder's children on every NSOutlineView child(_:ofItem:) call, so expanding a folder cost O(n² log n) main-thread time, and every FSEvents tick during a build rebuilt the whole tree with reloadData. Measured on an M-series Mac with the pre-rewrite code (/tmp harness copied from main):

Scenario	Before (main)	After (this PR)
List a 50k-entry folder	714 ms (contentsOfDirectory + fileExists per entry)	60 ms (getattrlistbulk, off main)
Sort 50k names	245 ms (localizedCaseInsensitiveCompare)	44 ms (precomputed natural-order keys, off main)
Expand a folder of 1,000 / 2,000 / 4,000 files	3.6 s / 20.6 s / 93 s on main (50k never finishes)	load+sort+diff 138 ms off main, then one insertItems batch
One file changes in an expanded 50k folder	full reload (see next row)	154 ms off main to re-list and diff; main applies a one-row insert
FSEvents tick with 200 expanded folders (50k rows)	868 ms re-list + 39.5 s reloadData and re-expansion on main	only visible changed folders re-list; collapsed ones re-list on next expand
Selection restore after a reload	27 ms linear row scan with path-prefix checks	row(forItem:) on stable nodes

"After" numbers come from swift test -c release in Packages/macOS/CmuxFileTree (FileTreePerformanceBenchmarkTests). The main-actor outline numbers for the 50k folder are printed by cmuxTests/FileExplorerOutlinePerformanceTests (see Testing).

Design

• CmuxFileTree package (no AppKit): FileTreeProvider is the one protocol for this Mac, SSH and Cloud, with a batch listDirectories(at:) and an optional change stream. FileTreeEngine is an actor that caches raw listings, filters hidden files, sorts, drops superseded loads by generation, and returns FileTreeChildrenDiff values shaped for NSOutlineView batch updates (path-keyed, O(n log n) with an LIS for moves). Toggling hidden files or the sort order re-derives cached listings without I/O. LocalFileTreeProvider uses getattrlistbulk(2) and one FSEvents stream per root. FileTreeViewStateRepository persists expansion, selection and scroll per workspace root.
• Store: FileExplorerStore keeps stable FileExplorerNode objects per path and applies diffs, so surviving rows keep identity, selection and expansion. Loads requested in one main-actor turn go out as one batch, so restoring expanded folders over SSH is one round trip. FSEvents batches only re-list folders that are visibly expanded; collapsed folders are marked stale and re-list when next expanded, so churn in node_modules or .build costs a set lookup. Only root chrome (rootPath, loading, status, contentRevision) is @Published; rows never pass through SwiftUI.
• Outline: the coordinator applies removeItems/insertItems inside beginUpdates, never reloadData except on a root or provider change. Icons are rendered once per kind/style/appearance by FileExplorerIconCache. Updates that arrive while a context menu is open wait and apply after it closes (Ctrl-click on a row in the Files sidebar panel crashes cmux (NSTableRowData rowViewAtRow context-menu-highlight exception) #12914).
• SSH lists over the workspace's sshOptions, which carry cmux's ControlMaster, one ls -1paFA per path inside one remote shell. Cloud lists in one guest exec per batch and now returns partial listings over 10,000 entries (with a badge) instead of failing.

Finder behavior

Option-click on a disclosure triangle and Option-Right/Left expand or collapse recursively (capped at 500 folders), type-select (prefix first, then substring), Command-Up (enclosing folder), Space (Quick Look), inline rename (F2 or the context menu), Command-Delete (Move to Trash), Edit > Copy/Paste of files, multi-select with Shift-arrows, drag out (file URLs for folders and files, path text for remote rows) and drag in (Finder semantics: same volume moves, Option or another volume copies, name collisions keep both). The context menu adds Open, Open in cmux, Quick Look, New File, New Folder, Rename, Move to Trash, Show Hidden Files, Sort By (Name, Kind, Date Modified, Size, direction, folders on top) and Refresh; the header gets a View Options button with the same items. Git status keeps the colored names and adds an M/A/D/R/U badge. Expansion, selection and scroll persist per workspace and root across restarts. The tree still follows the workspace cwd, the "open as pane" tool panel uses the same view, and Return and Command-Down still open the selection.

New shortcuts are Settings-backed actions (fileExplorerQuickLook, fileExplorerRenameSelection, fileExplorerToggleHiddenFiles, fileExplorerSelectParent) with schema, docs and translations. Command-Delete is fixed because the shortcut recorder cannot represent Delete.

Mutations (new, rename, trash, drop, paste) are local-only in this PR. Remote trees have no change stream; they re-list visible folders when the panel is shown or focused and on Refresh.

Files testing (from #15526)

• swift test --package-path Packages/macOS/CmuxFileTree: 28 tests pass locally (diff fuzzing against simulated NSOutlineView batch semantics, natural sort vs localizedStandardCompare, engine batching, superseded loads, hidden/sort without I/O, change-batch filtering, getattrlistbulk kinds/symlinks/UF_HIDDEN/Unicode, a live FSEvents event, view-state persistence and LRU, 50k benchmarks).
• swift test --package-path Packages/macOS/CmuxSettings: 441 tests pass locally, including the updated bare-first-stroke policy test.
• Added cmuxTests/FileExplorerTreeStoreTests.swift (SSH home resolution, requested cwd, batched SSH restore, SSH batch shell command against a real directory, stale load after provider swap, expansion across provider changes, hydration, error retry, recursive expansion, incremental diff keeping row identity and selection, stale collapsed folders, hidden/sort without re-listing, the Ctrl-click on a row in the Files sidebar panel crashes cmux (NSTableRowData rowViewAtRow context-menu-highlight exception) #12914 context-menu deferral, per-workspace persistence across stores, local create/rename/import) and cmuxTests/FileExplorerOutlinePerformanceTests.swift (50k-row expand and one-file refresh through a real NSOutlineView). These run in hosted CI; results are recorded below once CI finishes.
• Tagged build and SSH/Cloud live checks: see the build section below.

Find rewrite

From #15531 (merged into this branch at b4ef9d3).

Summary

The right sidebar's Find mode was a flat list of the first 500 literal, smart-case matches, local folders only, one row per line with the first column. This PR rebuilds it to VS Code's search panel behavior.

• Query options: Match Case, Match Whole Word and Use Regular Expression toggles, with an inline error for an invalid regex (local precheck, then ripgrep's own diagnostic). A details toggle shows "files to include" and "files to exclude" glob fields (VS Code comma syntax, src means any src folder) and a Use Exclude Settings and Ignore Files toggle. .git is never searched.
• Results: a flat, virtualized NSTableView grouped by file (FileSearchRowList; an NSOutlineView measured 6-7 s of main-thread time expanding 2,000 streamed files, the table appends the same 102,000 rows in 14 ms) (type icon, file name, dimmed directory, match count), one row per ripgrep submatch with the match highlighted in a preview trimmed around it. Collapse All / Expand All, Refresh, Clear, and Dismiss (context menu). Status line: "N results in M files", a searching state, and a limited state ("Search limited to the first 100,000 results").
• Streaming: ripgrep output is decoded off the main thread and applied to the outline at most once per frame; superseded queries are cancelled (the whole process group is signalled); typing is debounced through an injected Clock, never asyncAfter. A content change during a search waits for it to finish instead of restarting it.
• Keyboard: ⌘⇧F focuses Find and seeds the query from a single-line terminal or text selection. ↑ in the query field walks search history (persisted), ↓ moves into results (or forward in history while browsing it). ↑/↓/←/→ navigate and collapse in the results, Return opens, F4 / ⇧F4 step to the next or previous match and open it. Escape keeps its old behavior.
• Opening: a match opens at its line and column. The cmux preview selects and scrolls to the match (via a new FilePreviewRevealCenter, which also works for downloaded remote files); the preferred editor gets path:line:column.
• Scopes: local runs rg directly. SSH workspaces, previously "Local folders only", now search on the host by sending a POSIX script on ssh's stdin to sh -s, which finds rg (PATH plus common install dirs) or reports it missing. Cloud VMs use the same ripgrep arguments through the exec API. Missing rg names where to install it.
• Accent: match highlights, the selected result row and active option toggles use app.accentColor (cmux, system or custom) and update live.
• State: each workspace's query, options and results live in a session on the store (LRU of 8), so switching workspaces or Files/Find restores them. Existing shortcuts, socket/CLI verbs and Open as Pane are unchanged.

The testable core is a new leaf package, Packages/macOS/CmuxFileSearch: query to ripgrep argument mapping, the JSON decoder (UTF-8 byte offsets to UTF-16 columns, bytes payloads, invalid UTF-8), a posix_spawn process (arguments reach the child byte for byte; Process NFD-decomposes non-ASCII search text), the engine, the grouped result tree and history.

Replace and Replace All are deferred. A safe replace needs a preview diff and must write files atomically through three different transports (local, ssh, Cloud exec) while guarding against files that changed after the search. That is its own PR.

Merging with the Files rewrite: Find now lives in Sources/FileSearch/ and the package. Shared files changed only where unavoidable: FileExplorerView.swift (the container's Find subviews and search code replaced by one FileSearchPanelView; four coordinator drag-tracking methods lose fileprivate), FileExplorerStore.swift (one stored property, sshArguments made internal), FileExplorerTerminalPathInsertion.swift (container search extension removed), FileExplorerSearchResultsTableView.swift (now an NSOutlineView, name kept for the shared drag code).

Testing

Performance, 100,000 matches in 2,000 files (FileSearchPerformanceTests, CI swift-package-tests, debug build): decoding 17.5 MB of rg --json off the main thread 1,532 ms; applying it to the grouped tree in 268 per-frame batches 51 ms total, slowest batch 3.2 ms; 100,000 next-match steps 33 ms. FileSearchPanelTests.streamingPerformance streams the same 100k matches through the engine into the real NSOutlineView and prints main-thread time per update (see its CI log line PERF outline).

• CmuxFileSearch package: 51 Swift Testing tests (argv mapping, JSON parsing with multiple submatches, multibyte and invalid-UTF-8 bytes payloads, chunked streaming and limits, tree grouping/merging/navigation, engine debounce with a manual Clock, superseded-search cancellation, frame pacing, process group termination, byte-exact non-ASCII arguments, real rg end-to-end for every toggle and glob). Passed in CI swift-package-tests and locally.
• App tests (cmuxTests): new FileSearchPanelTests (debounce, grouped outline, deferred refresh on content change, Return/F4 open, per-workspace sessions, history, toggles, inline regex error, App hangs at 100% CPU on launch — FileExplorer SwiftUI update loop on macOS 26 (Tahoe) #4931 layout guard, 100k outline stream, open-location ranges, the SSH remote script run by a local sh for quoting and missing rg); ported drag-ownership, Cloud and shortcut tests. Run by CI app-host unit tests.
• Not verified live: the tagged app was not built separately (this branch ships inside the combined right-sidebar PR). GUI behavior, SSH against a real host and Cloud VM search are UNVERIFIED in a running app; the SSH script and Cloud exec parsing are covered by the tests above.
• Localization: 29 new keys in all nine macOS locales; localization_catalog.py check passes.

Changelog

Changed: Find in the right sidebar now works like VS Code's search: match case, whole word and regex toggles, include/exclude globs, results grouped by file with highlighted matches, history, F4 navigation, and search in SSH workspaces

Checklist

• Behavior changes have added or updated tests, or Testing says why not
• UI, settings, menu, schema, help-text or user-facing docs change: localization audited, and the result is stated above
• Reviewed with a subagent before merge (cmux-review), and all bot and human review comments resolved

Validation (combined branch)

• Bonsplit 264 builds with swift build.
• Fleet tagged build sbx at 4f0819c3bea (job e64490a443d192fbc99faccf) succeeded.
• Local preflight of sbx through /tmp/cmux-debug-sbx.sock, window in the background: right-sidebar focus turns the selected Files icon accent blue; simulate_shortcut cmd+shift+e returns it to gray; focus, hide, then show leaves it gray. Screenshots were compared for focused and unfocused states.
• Not verified: main tab emphasis in a key window, workspace switching, two windows, older macOS. The combined branch has not run hosted CI yet.

Changelog

Added: A right sidebar show/hide button that stays visible while the sidebar is hidden, with rightSidebar.toggleButton choosing the window corner, pane tab bar, left sidebar footer, or hidden
Changed: The Files sidebar opens huge folders like node_modules instantly, stays responsive during builds, and adds Finder behaviors: Quick Look, inline rename, new file and folder, Move to Trash, drag in and out, type-select, recursive expand, hidden-file and sort options, and restored expansion per workspace.
Changed: The selected right sidebar mode icon takes the accent color while the sidebar has keyboard focus, and the main tab loses its focus emphasis

Scope deferred remote Find queries to their Find session or request.

With --no-focus, setFindQuery switches to .find and stores the query when no Find host is mounted. That pending value is owned only by MainWindowFocusController. If Find is then deactivated or the workspace changes, a later .find host can consume the stale value and overwrite that workspace’s query.

Bind the deferred query to the per-workspace FileSearchSession or to a request token. Discard it when the Find mode, workspace, or host is superseded. Keep the existing FileSearchSession.owner behavior so only the visible Find panel receives session events. Do not change the intended durability of an already-applied session query.

<violation number="1" location="Sources/FileSearch/FileSearchAccent.swift:21">
P1: This observer can trap when a `.main` queue callback is not executing on the MainActor executor. Replace `MainActor.assumeIsolated` with an explicit `Task { @MainActor in ... }` hop before reading or mutating the actor-isolated state.</violation>
</file>

<file name="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeEngine.swift">

<violation number="1" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeEngine.swift:111">
P1: `discard(subtreeAt:)` does not invalidate in-flight first loads because it only visits cached listing keys. A removed, not-yet-loaded folder can therefore repopulate the cache after removal, and its next expansion receives a non-initial diff that cannot be applied to the new empty node; invalidate every matching generation key, not just `listings.keys`.</violation>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepArguments.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepArguments.swift:26">
P1: Every regex search requires a sufficiently new, PCRE2-capable remote `rg`, but SSH and Cloud targets are not checked before this flag is sent. Probe or enforce the required ripgrep capability, or select a compatible regex flag and report unsupported features clearly.</violation>

<violation number="2" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepArguments.swift:36">
P1: A later positive include glob can override this `!.git` rule, exposing `.git` contents when users include a broad pattern. Emit the mandatory `.git` exclusion after user globs, or otherwise prevent it from being overridden.</violation>

<violation number="3" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepArguments.swift:96">
P2: Negated patterns in the VS Code-style include field are inverted because this helper strips `!` before the caller adds include globs. Preserve include negation separately from exclude-field normalization so `!vendor` actually excludes vendor files.</violation>

<violation number="4" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepArguments.swift:104">
P1: Slash-containing globs are emitted as root-relative patterns, but searches pass an absolute `rootPath`. Make these patterns match absolute-root searches, otherwise include and exclude filters such as `src/app` silently fail.</violation>
</file>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchQuery.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchQuery.swift:50">
P1: This ICU precheck rejects valid ripgrep/PCRE2 expressions such as `(?|foo|bar)`, so those searches never reach local, SSH, or Cloud backends. Validate with the same ripgrep grammar without using `NSRegularExpression` as a hard execution gate.</violation>
</file>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchProcess.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchProcess.swift:140">
P2: `standardOutputChunks` drains stdout into an unbounded buffer, allowing a slow or absent consumer to retain the entire ripgrep output in memory. Use bounded buffering or couple pipe reads to consumer demand.</violation>

<violation number="2" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchProcess.swift:164">
P1: `waitForExit` blocks draining stderr until EOF before it observes child exit. A descendant that inherits stderr can keep that descriptor open after the child exits, so completion can hang forever; wait for the child while draining pipes non-blockingly and bound descendant cleanup.</violation>

<violation number="3" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchProcess.swift:206">
P2: `terminate()` sends only SIGTERM, so a child or descendant that traps or ignores it leaves cancellation blocked indefinitely. Escalate the process group to SIGKILL after a bounded grace period.</violation>
</file>

<file name="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileSystemEventStream.swift">

<violation number="1" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileSystemEventStream.swift:72">
P2: A failed `FSEventStreamStart` leaves this `AsyncStream` open forever with no events. Check the return value, invalidate and release the event stream, and finish the continuation on failure.</violation>

<violation number="2" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileSystemEventStream.swift:137">
P2: Dropped FSEvents are scoped too narrowly, so changes in loaded sibling directories can remain stale after an event overflow. Map kernel/user-dropped events to `displayRoot` (while keeping `MustScanSubDirs` scoped to the reported path) so the engine refreshes the whole monitored tree.</violation>

<violation number="3" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileSystemEventStream.swift:145">
P1: This bounded buffer silently drops change batches when the consumer falls behind, but the stream ignores `.dropped` from `yield`. Emit a root `subtrees` rescan batch when a yield drops an event, or otherwise use lossless buffering so the cached tree cannot miss changes.</violation>
</file>

<file name="Sources/ProcessSSHFileExplorerTransport.swift">

<violation number="1" location="Sources/ProcessSSHFileExplorerTransport.swift:110">
P1: These sequential EOF reads can deadlock SSH listings or downloads when stderr fills, leaving the Files operation stuck. Drain both pipes concurrently or non-blockingly, with bounded cancellation and process teardown.

(Based on your team's feedback about nonblocking child-process pipe draining.)</violation>

<violation number="2" location="Sources/ProcessSSHFileExplorerTransport.swift:201">
P2: A disk-full or pipe-read error leaves the SSH child running after `run()` throws. Catch copy failures, terminate and reap the process, mark the termination gate finished, then rethrow.</violation>

<violation number="3" location="Sources/ProcessSSHFileExplorerTransport.swift:265">
P2: An established SSH session can hang these operations indefinitely because the transport has no operation deadline or idle timeout. Add a cancellation-aware command deadline with bounded termination and reaping.

(Based on your team's feedback about bounded process termination and timeout checks.)</violation>

<violation number="4" location="Sources/ProcessSSHFileExplorerTransport.swift:332">
P2: The parser corrupts legitimate remote filenames ending in `*`, `@`, `=`, or `|`. Use an unambiguous machine-readable listing or determine the type separately instead of stripping suffixes by character alone.</violation>
</file>

<file name="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeViewStateRepository.swift">

<violation number="1" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeViewStateRepository.swift:35">
P2: Negative bounds crash `save` instead of being rejected or normalized. Validate these inputs in the initializer, or clamp them to nonnegative values before using them.</violation>

<violation number="2" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeViewStateRepository.swift:41">
P2: `state(for:)` does not mark a scope as recently used, despite the repository promising an LRU capacity. Touch the scope when reading it, including persisting the updated order, so recently restored scopes are not evicted first.</violation>

<violation number="3" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeViewStateRepository.swift:54">
P2: This guard can never take its early-return branch because the matching scope was removed immediately above. Move `removeAll` after the guard so unchanged saves avoid rewriting the full defaults blob.</violation>
</file>

<file name="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/LocalFileTreeProvider.swift">

<violation number="1" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/LocalFileTreeProvider.swift:24">
P2: This provider can permanently leave loaded directories stale during an event storm: once 64 batches queue, older directory changes are discarded without a root/subtree rescan marker. Use lossless coalescing or propagate any delivery drop as a subtree refresh before returning this watcher.</violation>

<violation number="2" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/LocalFileTreeProvider.swift:24">
P2: This call registers the recursive FSEvents stream synchronously on the main actor, so opening or reloading a root can block the Files UI during native registration. Start registration on a dedicated I/O queue (or make stream startup asynchronous) before exposing the watcher.</violation>
</file>

<file name="Sources/FileSearch/FileSearchPanelView+Table.swift">

<violation number="1" location="Sources/FileSearch/FileSearchPanelView+Table.swift:66">
P2: These context-menu actions resolve the row again when invoked, so a streamed update while the menu is open can make Copy, Insert, Reveal, or Dismiss operate on a different result. Capture stable file nodes (and the selected node set) when building the menu, or freeze row updates for the menu lifetime.</violation>
</file>

<file name="Sources/Panels/FilePreviewRevealCenter.swift">

<violation number="1" location="Sources/Panels/FilePreviewRevealCenter.swift:58">
P2: `request` broadcasts a path-only request to every tracked preview. When the same file is open in another window or duplicate tab, Find can scroll the wrong preview while the opened tab remains unchanged; associate the request with the panel returned by the open operation, or scope it by workspace and panel identity.</violation>
</file>

<file name="Sources/FileExplorerOutlineCoordinator+Actions.swift">

<violation number="1" location="Sources/FileExplorerOutlineCoordinator+Actions.swift:209">
P2: `contextMenuQuickLook` ignores the clicked menu item and toggles Quick Look for the current selection. Right-clicking an unselected file therefore previews the previous selection or beeps; select the represented node before toggling while preserving an existing multi-selection.</violation>

<violation number="2" location="Sources/FileExplorerOutlineCoordinator+Actions.swift:314">
P2: This alert forwards raw filesystem and `NSWorkspace` error descriptions to users, which can expose paths or internal error text. Show known `FileOperationError` messages and a generic localized fallback for other errors.</violation>

<violation number="3" location="Sources/FileExplorerOutlineCoordinator+Actions.swift:460">
P2: Cross-volume drops are rejected when the source mask is `.move`, despite the documented copy fallback. Permit copy for local cross-volume drags and include `.copy` in the local source operation mask.</violation>
</file>

<file name="Sources/FileSearch/FileSearchPanelView.swift">

<violation number="1" location="Sources/FileSearch/FileSearchPanelView.swift:261">
P2: Find can show stale results after being hidden. `update(store:)` skips revision handling while inactive, and `refreshIfStale()` ignores `contentRevision`, so a completed cached search is reused after filesystem updates. Track hidden-session staleness and rerun it on activation.</violation>
</file>

<file name="Sources/FileExplorerOutlineCoordinator.swift">

<violation number="1" location="Sources/FileExplorerOutlineCoordinator.swift:71">
P2: These main-queue notification callbacks unsafely assume MainActor isolation and can crash while changing style or finishing a scroll. Dispatch both callbacks with `Task { @MainActor [weak self] in ... }` instead of `MainActor.assumeIsolated`.\n\n(Based on your team's feedback about main-queue notification callbacks.)</violation>
</file>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepStreamDecoder.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepStreamDecoder.swift:25">
P2: This line buffer has no maximum size, so one huge or unterminated ripgrep record can grow `pending` without bound. Add a line-size cap and discard oversized records through their newline before resuming normal framing.

(Based on your team's feedback about oversized line framing caps.) .</violation>
</file>

<file name="Sources/RipgrepExecutableResolver.swift">

<violation number="1" location="Sources/RipgrepExecutableResolver.swift:128">
P2: `sshSearchFailed` exposes raw SSH stderr in the user-visible search status, which can include hostnames, usernames, and server diagnostics. Return the generic localized message here and keep detailed diagnostics only in sanitized internal logging.</violation>
</file>

<file name="Sources/FileExplorerStore+ViewState.swift">

<violation number="1" location="Sources/FileExplorerStore+ViewState.swift:58">
P2: Separate sidebar and tool-pane stores write the same scope, so closing a Files/Find pane can overwrite the sidebar's persisted expansion, selection, and scroll with that pane's independently loaded state. Share the store or coordinate per-scope writes before saving.</violation>

<violation number="2" location="Sources/FileExplorerStore+ViewState.swift:65">
P2: This guard treats preserved navigation as same-root in-memory state, so switching to a descendant root skips that root's saved view state. Distinguish same-root reloads from root changes, or clear the old navigation before restoring the new scope.</violation>
</file>

<file name="Sources/FileSearch/FileSearchPanelView+Drag.swift">

<violation number="1" location="Sources/FileSearch/FileSearchPanelView+Drag.swift:92">
P2: A late `endedAt` callback is silently dropped when SwiftUI replaced or cleared this table’s marker, leaving that session’s preview and transfer registrations uncleaned. Discard the capability using this exact session pasteboard in the guard-failure path, as the outline drag implementation does.</violation>
</file>

<file name="scripts/ci/package-test-lane.sh">

<violation number="1" location="scripts/ci/package-test-lane.sh:118">
P2: CmuxFileTree is also new in this PR (22 files, 1776 insertions) with a standalone headless test target, but unlike CmuxFileSearch it was not added to the PACKAGES list, so CmuxFileTreeTests (engine, diff, sort, view-state, local-provider suites) never run in the swift-package-tests lane. Add CmuxFileTree to the list next to CmuxFileSearch.</violation>
</file>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchHistory.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchHistory.swift:2">
P2: Synthesized decoding bypasses the constructor’s capacity clamp, so malformed or legacy persisted data can create a zero/negative-capacity history and make later recording drop entries or crash. Add a custom `init(from:)` that validates through the public initializer.</violation>
</file>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchResultTree.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchResultTree.swift:113">
P2: `remove(_:)` does not preserve the dismissal across the current streamed search, so a later batch for the same path re-adds the file immediately. Track dismissed paths and skip them until `removeAll()` begins the next search.</violation>
</file>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepJSONLineParser.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/RipgrepJSONLineParser.swift:190">
P2: Long matches can make previews twice the configured maximum and produce only a partial highlight. Clamp the preview window to the configured maximum while preserving scalar boundaries.</violation>
</file>

<file name="Sources/FileExplorerKeyboardShortcuts.swift">

<violation number="1" location="Sources/FileExplorerKeyboardShortcuts.swift:75">
P2: Rename currently changes the first row of a multi-selection, even though the Files context menu only enables Rename for one target. Require exactly one selected node before calling `beginRenaming` so F2 cannot rename an arbitrary item.</violation>
</file>

<file name="Sources/FileExplorerNSOutlineView.swift">

<violation number="1" location="Sources/FileExplorerNSOutlineView.swift:78">
P2: Type-select continuation consumes `/` during its one-second window, so the documented `/` quick-search shortcut fails after any type-select key. Exclude slash from continuation or clear the buffer before the later slash handler.</violation>
</file>

<file name="Sources/MainWindowFocusController.swift">

<violation number="1" location="Sources/MainWindowFocusController.swift:570">
P2: `fileSearchStatus` returns data from a retained Find host after the sidebar switches to Files. Require the current state and host presentation to be Find so `find_status` reports unavailable outside Find mode.</violation>
</file>

<file name="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeNameCollationKey.swift">

<violation number="1" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeNameCollationKey.swift:15">
P2: This key makes name sorting bytewise for non-ASCII filenames instead of Finder/localized. Accented filenames can therefore appear in a different order from the documented `localizedStandardCompare` behavior; use a locale-aware collation key or retain localized comparison for these names.</violation>
</file>

<file name="Sources/FileExplorerStore+FileOperations.swift">

<violation number="1" location="Sources/FileExplorerStore+FileOperations.swift:38">
P2: Creation is not serialized or retried after a collision. Two quick New File/Folder actions can race on the same name and lose one inline rename; serialize creation or retry naming after an existence failure.</violation>

<violation number="2" location="Sources/FileExplorerStore+FileOperations.swift:76">
P2: Renaming or moving an expanded directory drops expansion for every expanded descendant. Migrate each old-path prefix to the destination prefix, and remove the stale old keys, for both filesystem move paths.</violation>

<violation number="3" location="Sources/FileExplorerStore+FileOperations.swift:79">
P2: These operation-driven selection updates never schedule the persistent view-state write. If the app closes before another selection or root change, the next session restores the pre-operation selection, possibly a path that no longer exists.</violation>

<violation number="4" location="Sources/FileExplorerStore+FileOperations.swift:100">
P2: Trashing a root-level item leaves the store with no selection because root rows have no `parent`. Select the nearest surviving root sibling after removal, matching the anchor behavior used for nested items.</violation>
</file>

<file name="cmuxTests/CloudFileExplorerBehaviorTests.swift">

<violation number="1" location="cmuxTests/CloudFileExplorerBehaviorTests.swift:123">
P2: `matchLine` wraps the serialized payload in quotes, emitting `data` as a JSON string. `RipgrepJSONLineParser.parseMatch` reads it as a nested object (`object["data"] as? [String: Any]`, RipgrepJSONLineParser.swift:31), so a string value fails the cast and the line is dropped. Every line this helper builds is therefore rejected: `engine.tree.files`/`limited.groups` stay empty, and both new tests fail their result assertions. Real `rg --json` emits `data` as an inline object, so drop the surrounding quotes.</violation>
</file>

<file name="Sources/SSHFileExplorerProvider.swift">

<violation number="1" location="Sources/SSHFileExplorerProvider.swift:89">
P2: `resolveHomePath()` accepts a HOME value even when the provider became unavailable or its task was cancelled during the SSH await. Recheck task cancellation and current availability after the await so a stale completion cannot repopulate the root after reconnect.</violation>
</file>

<file name="Sources/CloudFileExplorerService.swift">

<violation number="1" location="Sources/CloudFileExplorerService.swift:222">
P2: The limit marker is detected inside the entire JSON payload, so a matching file whose content or path contains `__CMUX_LIMIT__` is reported as truncated even when ripgrep completed normally. Detect only a standalone marker line.</violation>

<violation number="2" location="Sources/CloudFileExplorerService.swift:228">
P2: Cloud searches stopped by the byte budget report the number already decoded as the configured result limit, so the UI can say “limited to the first 0/2 results” despite the actual cap being `lineLimit`. Pass `lineLimit` as the completion limit, matching the local backend.</violation>
</file>

<file name="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeSortOrder.swift">

<violation number="1" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/FileTreeSortOrder.swift:74">
P2: Unknown metadata is being treated as a real epoch or zero value. Preserve the optional state and define a consistent unknown placement (for example, after known values) so Date Modified and Size sorting do not misorder partially populated listings or silently degrade remote listings to zero-valued ties.</violation>
</file>

<file name="Sources/AppDelegate.swift">

<violation number="1" location="Sources/AppDelegate.swift:18152">
P2: These exclusions can swallow configured Finder shortcuts that collide with a stale default menu key. Restore the prior prevention behavior or route `handleFinderActionShortcut` before suppressing the event.</violation>
</file>

<file name="Sources/FileSearch/FileSearchQueryBar.swift">

<violation number="1" location="Sources/FileSearch/FileSearchQueryBar.swift:100">
P2: These Find labels fall back to English in the catalog's `bs`, `da`, `it`, `km`, `nb`, `pl`, `pt-BR`, `ru`, `th`, `tr`, and `uk` locales. Add entries for every supported catalog locale for the placeholder and all `fileSearch.*` labels introduced below.

(Based on your team's feedback about complete xcstrings locale coverage.)</violation>
</file>

<file name="Sources/FileExplorerCellView.swift">

<violation number="1" location="Sources/FileExplorerCellView.swift:184">
P2: Clear the badge text when hiding it. Otherwise recycled rows can retain an unnecessary blank or truncated suffix after their status changes.</violation>

<violation number="2" location="Sources/FileExplorerCellView.swift:223">
P2: `endRenaming` does not restore the row’s original text color. Preserve the pre-rename color or reconfigure the row when editing ends so canceling or failing a rename does not permanently lose git/error coloring.</violation>
</file>

<file name="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchRowList.swift">

<violation number="1" location="Packages/macOS/CmuxFileSearch/Sources/CmuxFileSearch/FileSearchRowList.swift:54">
P2: This scans every visible match of the last file on each streamed update. A large file arriving over multiple frames makes row maintenance quadratic; use `row(of:)` to locate the file row in logarithmic time.</violation>
</file>

<file name="Sources/Panels/FilePreviewTextEditor.swift">

<violation number="1" location="Sources/Panels/FilePreviewTextEditor.swift:77">
P2: This callback runs before `scrollView.documentView = textView`, so a loaded search-reveal request can be consumed while the text view has no superview and its scroll/indicator operations have no effect. Invoke the callback after installing the document view and laying out the editor.</violation>
</file>

<file name="Sources/FileExplorerSearchField.swift">

<violation number="1" location="Sources/FileExplorerSearchField.swift:43">
P2: `handleMatchNavigation` must ignore marked-text composition, just like the query delegate and `handleOpenSelectionShortcut`; otherwise F4 can interrupt an active IME composition and open a search result. Cast the editor to `NSTextView` and require `!editor.hasMarkedText()` in this guard.</violation>
</file>

<file name="Sources/FileSearchScope.swift">

<violation number="1" location="Sources/FileSearchScope.swift:54">
P2: This exposes an SSH search backend even when the provider is unavailable. Find can then attempt a remote SSH search instead of failing closed; return no backend while `provider.isAvailable` is false.</violation>
</file>

<file name="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/DirectoryBulkReader.swift">

<violation number="1" location="Packages/macOS/CmuxFileTree/Sources/CmuxFileTree/DirectoryBulkReader.swift:42">
P2: Cancelled tree loads continue scanning large directories until completion. Check task cancellation before each `getattrlistbulk` call so switching roots or tearing down the tree stops obsolete work promptly.</violation>

P2: Creation is not serialized or retried after a collision. Two quick New File/Folder actions can race on the same name and lose one inline rename; serialize creation or retry naming after an existence failure.

P2: These operation-driven selection updates never schedule the persistent view-state write. If the app closes before another selection or root change, the next session restores the pre-operation selection, possibly a path that no longer exists.

P2: Cloud searches stopped by the byte budget report the number already decoded as the configured result limit, so the UI can say “limited to the first 0/2 results” despite the actual cap being lineLimit. Pass lineLimit as the completion limit, matching the local backend.
