Problem

The desktop sidebar had no way to navigate sessions. Sessions were reachable only from the session list page, with no per-repo grouping, no live indication of which sessions were busy, and no search. The mobile tab bar showed Schedules inside a repo instead of source control, and the repo quick-switch sheet duplicated repo/session rendering that the desktop sidebar needed.

Fix

  • Add DesktopSessionTree to the desktop sidebar: a searchable list of navigable repos whose sessions load lazily per repo, with the active repo expanded and one repo open at a time.
  • Add a pure sidebar-session-tree model (buildSidebarRepoGroups, selectNavigableRepos, getActiveRepoId, isCurrentSessionItem) and a useSidebarRepoGroups/useNavigableRepos data layer.
  • Track per-session status (idle/busy/retry/compact) in sessionStatusStore, fed by the SSE event stream and directory-scoped status snapshots, with optimistic-active and revision-guarded snapshot application.
  • Extract shared navigation components (RepoNavGroup, RepoSessionNavList, SessionNavRow, NewSessionButton, SearchClearButton, SessionNavStatus) reused by the desktop tree and the mobile RepoQuickSwitchSheet.
  • Show a Git tab and hide Schedules inside a repo on the mobile tab bar, and add Repos and Assistant entries to the session More drawer.
  • Consolidate root-session selection and pinned-key handling in session-partition, and replace the CommitsTab local relative-time formatter with a shared formatShortRelativeTime util.

Testing

  • pnpm typecheck:frontend: exit 0.
  • pnpm lint:frontend: exit 0.
  • pnpm test:frontend: 1551 tests pass (138 files).

Summary by CodeRabbit

  • New Features
    • Expanded desktop navigation includes repository and session lists, search across ready repositories, pinned and recent sessions, live session status indicators, and quick session creation.
    • Desktop sidebar sections can be collapsed, with preferences remembered between visits.
    • Mobile repository navigation includes a Git tab. The More menu offers repository navigation and an Assistant shortcut where available.
  • Bug Fixes
    • Pinned sessions remain accessible even when they fall outside the initial session list.
    • Session activity indicators stay up to date while connected, including after reconnecting.
    • Repositories that are cloning or have failed to clone are labeled as not ready.

- Add a searchable, collapsible session tree to the desktop sidebar, grouped by repository with pinned and time-bucketed ordering.
- Track per-session busy, retry, and compact status in a shared store fed by the SSE event stream and scoped by directory.
- Extract shared navigation components reused by the desktop tree and the mobile repo quick-switch sheet.
- Show a Git tab and hide Schedules inside a repo on the mobile tab bar; add Repos and Assistant entries to the session More drawer.
- Replace the CommitsTab local relative-time formatter with a shared formatShortRelativeTime util.

📝 Walkthrough

Walkthrough

Desktop and mobile navigation now share repository and session helpers. The desktop sidebar adds collapsible sections and a repository session tree. EventContext polls and reconciles active-session status, while session-list invalidation supports directory-scoped updates.

Changes

Repository and Session Navigation

Layer / File(s) Summary
Repository and session data
frontend/src/components/navigation/sidebar-session-tree.ts, frontend/src/components/navigation/sidebar-session-tree.test.ts, frontend/src/components/session/*, frontend/src/hooks/useSidebarRepoGroups.ts, frontend/src/hooks/useOpenCode.ts, frontend/src/lib/navigation.ts, frontend/src/lib/navigation.test.ts, frontend/src/lib/sessionKey.ts, frontend/src/lib/sessionKey.test.ts, frontend/src/lib/utils.ts, frontend/src/lib/utils.test.ts
Shared helpers parse repository routes, build session paths and pinned keys, select root sessions, and format branch labels and relative times. Sidebar groups can fetch missing pinned sessions and report whether more sessions exist.
Desktop sidebar and session navigation
frontend/src/components/navigation/DesktopSidebar.tsx, frontend/src/components/navigation/DesktopSidebar.test.tsx, frontend/src/components/navigation/DesktopSessionTree.tsx, frontend/src/components/navigation/DesktopSessionTree.test.tsx, frontend/src/components/navigation/RepoSessionNav.tsx, frontend/src/components/ui/sidebar.tsx, frontend/src/components/ui/sidebar.test.tsx, frontend/src/hooks/useSidebarCollapsed.ts, frontend/src/hooks/useSidebarCollapsed.test.tsx, frontend/src/components/repo/RepoList.tsx, frontend/src/components/source-control/CommitsTab.tsx, docs/features/chat.md
The desktop sidebar displays collapsible Sessions and Menu sections and a repository session tree. Repository groups show readiness states and an “All sessions” link when another page exists. Search, pinning, and pending-request indicators are covered by tests. Repository and commit activity use the shared relative-time formatter.
Mobile repository and session navigation
frontend/src/components/navigation/MobileTabBar.tsx, frontend/src/components/navigation/MobileTabBar.test.tsx, frontend/src/components/navigation/MoreDrawer.tsx, frontend/src/components/navigation/MoreDrawer.test.tsx, frontend/src/components/navigation/moreDrawerItems.ts, frontend/src/components/navigation/moreDrawerItems.test.ts, frontend/src/components/navigation/RepoQuickSwitchSheet.tsx, frontend/src/components/navigation/RepoQuickSwitchSheet.test.tsx, frontend/src/hooks/useDialogParam.ts, frontend/src/components/ui/bottom-sheet.tsx, frontend/src/pages/RepoDetail.tsx, frontend/src/pages/SessionDetail.tsx
Repository routes show a Git tab that opens the source-control dialog. The repository sheet uses shared session navigation, and the More drawer opens the Repos sheet and conditionally offers an Assistant action on session routes. “New Session” is removed from primary navigation actions on repository and session detail routes.

Session Status Synchronization

Layer / File(s) Summary
Global status snapshots
frontend/src/stores/sessionStatusStore.ts, frontend/src/stores/sessionStatusStore.test.ts
The status store uses global snapshot tokens and revision tracking. It ignores older snapshots and preserves status changes made while a snapshot is in flight.
Active-session polling and event updates
frontend/src/contexts/EventContext.tsx, frontend/src/contexts/EventContext.test.tsx, frontend/src/hooks/useSSE.ts, frontend/src/hooks/useSSE.test.tsx, frontend/src/lib/queryInvalidation.ts, frontend/src/lib/queryInvalidation.test.ts
EventContext fetches active-session snapshots on connection and polls every five seconds while connected. Live status events update the store, and relevant events invalidate session-list caches by directory. useSSE no longer synchronizes session status.

Merge Risk: 🟡 Moderate · up to 3894b

On short screens, account actions may become inaccessible. Navigation can also lose a manually expanded repository, the Assistant action lacks normal link options, and live retry or compact status can disappear after polling. Resolve the sidebar access and status issues before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3894b

The new navigation remains available only to signed-in users, and no new permission bypass was established. The main remaining risk is an unverified assumption about how sessions are identified across repositories.

Retained concerns

  • Low · architecture · inferred: The new multi-repository view mixes directory-qualified session keys with status and pending-action indicators keyed only by session ID. If IDs can repeat across directories, a row could display another repository's state. Global ID uniqueness was not established; this is an identity-contract concern, not a verified authorization bypass.
Security review details

Security Blast Radius

  • inferred — A session-identity collision, if possible, could affect indicators across repository rows visible to the same signed-in client. The inspected row renders indicators and navigation, not a permission-approval operation.

Trust Boundaries and Controls

  • observed — The client-side authentication gate precedes the new desktop tree, but session creation delegates a repository directory to the session API. The available frontend source does not establish the server's authorization policy for that directory.

Resilience and Maintainability Implications

  • observed — Disconnect and cleanup invalidate outstanding status fetches, while token ordering protects against older snapshots. These controls address stale client state but do not establish cross-repository identity uniqueness.

Hardening Proposals

  • proposed — Establish the producer-side session-ID uniqueness contract for all repositories, or consistently qualify cross-repository client state by directory and session ID. Confirm that session APIs authorize directory and session access independently of navigation.

Use a link for the Assistant route.

The new Assistant button navigates to assistantCta.to. A button does not provide link behaviors such as opening the route in a new tab. Render a React Router Link with to={assistantCta.to} instead. Based on learnings: use a Link for navigation to another route and a Button for an in-page action.

Allow the Menu section to shrink on short viewports.

Sidebar is a h-dvh flex flex-col container, and its account row follows the Menu section. The Menu section uses flex-1 min-h-fit, so its minimum height can remain equal to its content height. This can push the account row below the viewport instead of allowing the overflow-y-auto content to scroll.

Replace min-h-fit with min-h-0.

Suggested fix
-              className="flex-1 min-h-fit border-t border-border"
+              className="flex-1 min-h-0 border-t border-border"
