What this does

Adds an opt-in Conversations view to the left sidebar picker. It lists running coding-agent sessions above paginated history, with transcript search and a provider filter. Clicking a running session focuses its pane, and clicking a past one reopens it through normal workspace routing. Nothing changes for anyone who hasn't turned it on.

  • Live rows come from the agent chat registry. History and search come from the Vault index (SessionIndexStore). The two are joined on agent and session identity, so a running session never also shows up in history.
  • The filter menu narrows the list to one provider. Its options come from the store's cached agent list plus live and paginated agents. That's feat: add provider filtering to Conversations sidebar #13355, folded in here.
  • The beta toggle is Settings > Beta Features > Conversation Sidebar, or sidebar.beta.conversations.enabled in cmux.json (schema, template and parser). It's localized in all 9 app locales and in the web locales.
  • The conversation-sidebar-release PostHog flag gates the feature, and the local toggle can't override it. When the flag is off or unavailable, the picker hides the entry and a saved Conversations selection falls back to the workspace sidebar.
  • The sidebar observes a typed revision stream from AgentChatTranscriptService, and activity-only record changes don't rebuild it. The phone descriptorChanged frames are the same as on main.
  • The body reads merged history from view state that's recomputed when its inputs change, and it doesn't schedule live-index refreshes. That follows the SwiftUI list-boundary rule.

Not included

These parts of the earlier fork experiment (#57/#68) aren't included: grouping and project folders, pins and shortcuts, New chat, drag and reorder, and Spaces/tile navigation.

Validation

At ef3e399f2bf, after merging main at 560664970a5 and aligning all submodules to that head.

  • python3 scripts/verify-local.py --all: all 15 repository checks passed.
  • git diff --check: passed.
  • ConversationSidebarRegressionTests covers Dock/live projection, alias revision changes, activity-only suppression, provider filtering, and refresh behavior. Native tests run in CI only.
  • CI: run 36769912988. The app-host compile reached the source build and stopped on current main's Sources/AppDelegate+WorkspaceActionSave.swift:126 (switch must be exhaustive), outside this PR's feature diff.
  • iOS: run 36769912309. Both attempts stopped before tests because the runner could not fetch refs/pull/13322/merge; no iOS test failure was reported.
  • Cloud VM guest-install is blocked by current main's CREATE INDEX CONCURRENTLY migration. CLA policy infrastructure has also been rate-limited. These are outside the feature diff.

The CI tour is conversations-sidebar-tour. Its media section will appear when an app-host build completes; the current app-host compile blocker prevents that tour from running.

Review: exact-head review receipt. The review found and the branch fixed the settings overload, hook-store alias revision, reload race, per-row target scan, release-gate observation, and Dock alias ownership issues.

Summary by cubic

Adds an opt-in, release-gated Conversations sidebar that unifies live coding-agent sessions with paginated history, transcript search, and provider filtering in the left sidebar. Live sessions are deduplicated from history so clicking one opens it in place; the default layout is unchanged.

  • Live sessions hosted in a window or workspace Dock resolve to the Dock instead of being dropped, with regression coverage pinning activation without duplicate launches. Clicking a live session focuses its owning panel; process-index fallback stays scoped to the Dock workspace's identity and returns canonical Dock panel IDs so an aliased surface focuses without relaunching.
  • The conversation-sidebar-release PostHog flag gates the feature; when off, the picker hides the entry and a saved selection falls back to the default workspace sidebar. Both sidebar routing paths observe the flag reactively.
  • Phones keep main's descriptor behavior; the sidebar uses its own predicate that ignores version bumps, and merged history is held in view state instead of being recomputed on every body pass.
  • Provider options are cached during pagination so the filter stays populated as history loads, pagination discovers new providers at each page, and paginated history is fenced against index reload races.
  • Adds the beta setting, cmux.json schema support and path registration, localization in all app and web locales, a CI dogfood tour for dock focus and provider filtering, and regression coverage.
  • Includes the reviewed main-branch merge fixes: settings-row anchoring, restored lazy-layout tests, phone descriptor parity, history projection moved out of body, paginated history invalidated on index reloads, and sidebar revisions advanced when hook-store aliases are backfilled; regenerated the embedded schema, merged string catalogs, and updated sidebar tests for the new session index store parameter.

Written for commit ef3e399. Summary will update on new commits.

Full details: Cmux Swift Blocking Runtime

Explanation

The PR adds a production timing wait in Sources/ConversationSidebarView.swift:478: try? await ContinuousClock().sleep(for: .milliseconds(150)). The wait implements search debounce in updateSearchResults, and the file is registered in the main application target. This is newly introduced; the base ref has no ConversationSidebarView.swift. It is not test scaffolding or UI animation timing. The rule treats production sleeps as failures, including timing-based synchronization beyond thread-blocking waits. Other timers and locks found in changed files are pre-existing and were not introduced by this diff.

Resolution

Replace the direct ContinuousClock().sleep debounce with a cancellation-aware debounce scheduler or timer abstraction that emits a completion event/callback, or use an equivalent event-driven search coordinator. Start the search from that event and preserve cancellation when searchText changes.

Full details: Cmux Cache Substitution Correctness

Explanation

The new Conversations history path substitutes the in-memory expandedHistory snapshot for fresh Vault reads after pagination. loadMoreHistory() obtains authoritative per-agent data through loadRecentSessions, then stores it in expandedHistory (Sources/ConversationSidebarView.swift:434-460); subsequent renders use recentHistory(initial: store.entries, expanded: expandedHistory) (Sources/ConversationSidebarView.swift:320-322). recentHistory only prefers current metadata for overlapping IDs and preserves expanded entries that are absent from the current store (Sources/ConversationSidebarSupport.swift:73-114). A history notification calls store.reload() but does not clear or revalidate expandedHistory (Sources/ConversationSidebarSupport.swift:239-245). Therefore a deleted or changed older session can remain visible and be passed to SessionEntryResumeCoordinator.open (Sources/ConversationSidebarView.swift:370-385, 487-496). The cold path is partly handled because the view reloads an empty store on appearance (Sources/ConversationSidebarView.swift:248-253), but stale expanded history is not freshness-checked or invalidated.

Resolution

Tie expandedHistory to the authoritative SessionIndexStore reload/source generation and invalidate it whenever the underlying Vault sources can change. Clear the expanded snapshot and reset pagination when a reload or history invalidation occurs, then repopulate it from a fresh loadRecentSessions result. Add a freshness check or source event for changes not covered by agentChatSessionHistoryDidChange, including modified and deleted older entries. Do not display or activate an expanded entry after its source generation becomes stale. Add regression tests for an expanded entry that is modified, deleted, or removed by a reload.

Full details: Cmux Algorithmic Complexity

Explanation

The new Sources/ConversationSidebarView.swift introduces unbounded projection work directly in SwiftUI body. At lines 125-129, every body evaluation calls projectedRows and then filters the complete row snapshot. projectedRows scans historySource at lines 324-350, filters and sorts all live rows at lines 353-368, and authoritativeLiveRows rescans all live session records at lines 391-401. The code has no cached projected-row snapshot and no explicit bound for live records. This violates the rule for repeated sorting/filtering in a hot UI path without a cache or size bound, especially at roughly 1000 sessions. The same new loop also calls SessionEntryResumeCoordinator.activeTarget once per history entry at line 327. That existing helper scans tabManager.tabs and each workspace's panel snapshots (Sources/SessionIndexView.swift:37-50). Therefore the new history loop creates a per-entry rescan of the workspace/panel collections, which is a nested full-collection scan. The PR adds the caller, so this is PR-caused even though the helper itself predates the PR. The PR provides no benchmark or measurement that justifies this shape.

Resolution

Build a single session-identity-to-active-target dictionary from the tab/workspace snapshot, then resolve all history entries with O(1) lookups. Move projectedRows and its sort/filter work out of body into a cached snapshot updated only when the live registry, index, or relevant tab state changes. Keep visible-row pagination separate from the source snapshot, and add a benchmark or explicit threshold if any slower fallback remains.

Full details: Cmux Swift `@Concurrent`

Explanation

The PR introduces a main-actor file-scanning path without a concurrent boundary. SessionIndexStore is @MainActor, so the new loadRecentSessions method in Sources/SessionIndexStore+GlobalSearch.swift is actor-isolated. ConversationSidebarView.loadMoreHistory() calls it from the @MainActor view at line 446. The method then invokes the nonisolated async defaultAgentOrder and loadAgents; loadAgents is an async fan-out over agent session readers and has no @concurrent annotation. This new path performs bounded disk/session parsing from UI isolation. Existing search uses a separate @concurrent static core, but the new history-loading path does not provide that boundary.

Resolution

Move the recent-history loading into a nonisolated @concurrent static/core function, or wrap the heavy call in an explicit Task.detached/equivalent hop. Capture the required ampSessionRepository and other MainActor state before the hop, then return only Sendable result data to the UI. Keep the UI state updates on @MainActor; do not add @concurrent to a function that directly accesses MainActor-isolated store state.

Full details: Cmux Swift Package Boundaries

Explanation

The PR adds independently testable Conversations domain logic to the app target. Sources/ConversationSidebarSupport.swift:5-170 introduces ConversationSidebarProjection for identity, agent presentation, history merging, filtering, deduplication, and pagination. Sources/ConversationSidebarSupport.swift:172-208 adds a refresh scheduler that is also directly unit-tested. These parts do not require AppKit, Ghostty, or SwiftUI view composition. cmuxTests/ConversationSidebarRegressionTests.swift:15-188 tests the projection directly, and :248-296 tests the scheduler. The Xcode project registers both production files in the app Sources phase at cmux.xcodeproj/project.pbxproj:14075-14076. ConversationSidebarView and menu wiring can remain app code, but the new core logic violates the rule's app-root boundary condition.

Resolution

Create a small macOS SwiftPM target named CmuxConversationSidebarCore. Move the deterministic projection and refresh-scheduling logic into it, with ConversationSidebarProjection as the first public type. Define small public Sendable snapshot/value types or protocols for session identity, agent presentation, history entries, and pagination limits instead of importing app-internal SessionEntry, Workspace, SessionIndexStore, or TerminalController. Move the projection and scheduler unit tests into the package test target. Keep ConversationSidebarView, ConversationSidebarLiveRefreshModifier, workspace/session routing, NotificationCenter integration, and AppKit/SwiftUI menu composition in the app target as adapters.

Full details: Cmux Full Internationalization

Explanation

The PR adds seven user-facing keys to Resources/Localizable.xcstrings, but each key has translations for only 9 locales. The touched catalog already supports 20 locale codes, so the new entries omit bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and uk. The web schema description does include entries for every locale in web/i18n/routing.ts, and the new Swift UI text uses localized APIs, but the app catalog additions are incomplete.

Resolution

Add translated stringUnit entries for bs, da, it, km, nb, pl, pt-BR, ru, th, tr, and uk for all seven new keys in Resources/Localizable.xcstrings: featureFlags.conversationSidebar.title, featureFlags.conversationSidebar.description, settings.betaFeatures.conversationSidebar, settings.betaFeatures.conversationSidebar.subtitleOn, settings.betaFeatures.conversationSidebar.subtitleOff, sidebar.provider.conversations.title, and sidebar.provider.conversations.subtitle. Mark each completed translation as translated.

Full details: Cmux Architecture Rethink

Explanation

The PR adds a production notification side channel and a timing-based refresh repair. AgentChatTranscriptService now posts agentChatSessionRecordsDidChange and agentChatSessionHistoryDidChange. ConversationSidebarLiveRefreshModifier installs two unscoped NotificationCenter async observers, then ConversationSidebarRefreshScheduler cancels tasks and uses await Task.yield() to coalesce bursts and preserve a trailing refresh. This introduces lifecycle state outside the authoritative AgentChatSessionRegistry callbacks and SessionIndexStore state. It leaves refresh ordering and missed-update behavior representable instead of enforcing one state transition. The production observer and scheduler are changed-code causes, not test-only synchronization.

Resolution

Make the agent-session owner publish a typed change stream or monotonic revision from AgentChatSessionRegistry/AgentChatTranscriptService. Let one explicit conversation-sidebar coordinator own the refresh lifecycle and derive value snapshots from that source. Remove the process-wide NotificationCenter posts and observers, the separate revision/cache plumbing, and the ConversationSidebarRefreshScheduler/Task.yield() timing repair. Drive history updates through SessionIndexStore's existing published state or an owner-controlled reload API. The first migration cut is to replace the two notification loops with one coordinator consuming the registry-owned change stream and to assert that each source revision produces one projection snapshot.

Full details: Description check

Explanation

The description explains the behavior, scope, implementation, validation, localization, feature flag, and regression coverage. However, it uses a Validation heading instead of the required Testing heading, leaves the Demo Video section empty despite this being a UI change, and leaves all checklist items unchecked.

  • P2 Production Test Seam Added Sources/SessionIndexStore.swift:706 ▶

    The new replaceEntriesForTesting method is a DEBUG-only test seam in a production Sources/ file, and its only callers are tests. This violates the repository directive that tests access internal state through @testable import instead of adding ForTesting APIs to production types. This repository requirement must be satisfied before merging.

The missing conversation-sidebar feature-flag localization is now covered for all 9 supported locales (commit eb950f5; localization catalog check passes). The branch also contains the later search-delay/trailing-refresh fixes. I’m leaving the broader activity coalescing, pagination snapshot reuse, and notification ownership findings as separate follow-up work rather than widening this feature PR.

Correction: CI run 36703441672 failed in unrelated lanes. macOS compile admission reports missing types TabPresence in Sources/TerminalSharingDisplay.swift and BonsplitContrastPalette in Sources/TerminalSizeBoundsOverlayView.swift. Neither file is changed by this PR. iOS simulator tests timed out collecting diagnostics after 600 seconds. Current-main run 36703754802 is queued for baseline evidence. All PR-touched static checks and 81 of 87 CI checks passed.

Baseline evidence: current-main CI run 36703754802 has also failed macOS compile admission while the PR run failed the same lane. Its compile job is already marked failure; GitHub has not released logs until the remaining package job completes. This confirms the required aggregate failure is inherited from current main, not from the Conversations or Dock files.

Submodule correction pushed at 1925916: merged latest main b36a9b3 and aligned vendor/bonsplit to 83857fa043bd (Ghostty and Homebrew already matched main). I dispatched CI 36728937195 and iOS 36728760475. Same-job main iPad baseline 36729004719 passed ios-simulator (ipad), so the earlier PR timeout was not yet classifiable as infrastructure; the corrected PR iOS result is pending.

Restore the injected custom sidebar setting lookup, invalidate paginated history after index reloads, and advance sidebar revisions when hook-store aliases are backfilled. Add regression coverage for alias changes and document the French Actions catalog identity.

Observe the live release gate, fence paginated history against reload races, and resolve live fallback targets in one topology pass. Add the CI dogfood tour for provider filtering and Dock focus.

Return canonical Dock panel IDs from process-index fallback targets so clicking a live aliased surface focuses the owning panel.

Keep process-index routing tied to the Dock workspace identity before normalizing aliased panel IDs.

Review at 963f40f: approved after an exact-head pass.

Fixed: the missing injected settings lookup, hook-store alias revision updates, reload-safe history pagination, one-pass live target lookup with workspace and Dock ownership checks, reactive release-gate reads, and the CI Conversations tour.

Left: no unresolved CodeRabbit, Greptile, or Cubic threads. CLA Assistant and Cloud VM guest-install are failing in the shared CI infrastructure; their logs show the GitHub API rate limit and a main migration using CREATE INDEX CONCURRENTLY inside a transaction. The feature code does not touch those paths.

Bot follow-up:

  • SessionIndexStore.replaceEntriesForTesting stays a #if DEBUG seam with one cmuxTests caller. entries is private(set), so moving the fixture into a test extension would require widening production access. This follows existing DEBUG-only test seams.
  • The localization summary’s 20-locale warning does not apply to the macOS catalog validator. Conversations has all nine required macOS locales, and the web message catalogs cover the additional web locales.
  • The sidebar history reload race and per-row live-target scans were fixed in this head. The fallback now uses a single topology pass and preserves workspace and Dock ownership, including Dock aliases.
