Concise audit for issue #276, focused on `vite-frontend/src/pages` and `src/api`.

a) What already exists

1. Dashboard traffic auto-refresh
- Dashboard data is loaded via async API calls in a hook, not by page reload:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard/use-dashboard-data.ts`
  - `useDashboardData()` calls `getUserPackageInfo()` and `getAnnouncement()`.
- The 24h traffic chart is already rendered from `statisticsFlows`:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard.tsx`
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard/components/flow-chart-card.tsx`

2. Node status real-time updates
- This is the strongest existing area.
- WebSocket realtime hook already exists:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-realtime.ts`
  - `useNodeRealtime()`
- Offline debounce exists:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-offline-timers.ts`
- Node page consumes websocket messages and updates local state without reload:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
  - `handleWebSocketMessage()`
  - `loadNodes()`
- Realtime also includes system info updates and upgrade progress updates.

3. Form submissions without full page reload
- Broadly already implemented across main CRUD pages using async handlers + modal close + state refresh.
- Examples:
  - Nodes: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
    - `handleSubmit()`
  - Tunnels: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/tunnel.tsx`
    - `handleSubmit()`
  - Forwards: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
    - `handleSubmit()`
  - Users: `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
    - `handleSubmitUser()`
- I did not find page reload patterns in these CRUD pages (`location.reload` / `window.location.reload` absent there).

4. Local/partial list refresh after CRUD/toggle
- Some local optimistic/partial updates already exist:
  - Node delete updates local state directly:
    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
    - `confirmDelete()`
  - Node edit updates local item directly:
    - `handleSubmit()` edit branch
  - Forward service toggle uses optimistic local update + rollback on failure:
    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
    - `handleServiceToggle()`
  - Sorting persists locally and updates item `inx` in-memory after success:
    - Node `handleDragEnd()`
    - Tunnel `handleDragEnd()`
    - Forward `handleDragEnd()`

5. Batch operation progress UI
- Node upgrade has actual per-node progress UI:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
  - `upgradeProgress` state
  - websocket `type === "upgrade_progress"` handling in `handleWebSocketMessage()`
  - `<Progress />` render around lines ~1307+
- Forward batch actions are factored and return structured outcomes:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward/batch-actions.ts`

6. Search/filter instant response
- Instant client-side filtering already exists in:
  - Nodes: `sortedNodes` memo filters by `searchKeyword`
    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
  - Tunnels: `sortedTunnels`
    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/tunnel.tsx`
  - Forwards: `orderedForwards`
    - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
- Forward also has instant client-side filter dropdowns (`filterUserId`, `filterTunnelId`).

b) What is missing or partial

1. Dashboard traffic auto-refresh: missing
- `useDashboardData()` only fetches once on mount.
- No polling, websocket, refetch trigger, focus refresh, or manual refresh hook.
- So “AJAX no-refresh” exists only for initial load, not ongoing refresh.

2. Node realtime: partial but good
- Realtime status/system-info exists only for nodes.
- It reconnects with limited retries (5 attempts) and then stops.
- `loadNodes()` initially sets `systemInfo: null`, so a full reload can temporarily wipe metrics until WS catches up again.
- No obvious fallback polling if websocket dies permanently.

3. Form submission no full reload: mostly done
- CRUD forms are already async and modal-driven.
- But post-submit refresh style is inconsistent:
  - some do local patch,
  - many do full page-level list refetch (`loadData()`, `loadUsers()`, `loadNodes()`).

4. Local/partial list refresh after CRUD/toggle: partial/inconsistent
- Forward toggle is good and local.
- Node edit/delete are relatively local.
- But many operations still refetch the whole page dataset:
  - Tunnel create/update/delete -> `loadData()`
  - Forward create/update/delete -> `loadData()`
  - User create/update/delete -> `loadUsers()`
  - User tunnel assignment/update/remove -> `loadUserTunnels()`
- This is AJAX and avoids full browser reload, but not “partial/local refresh” in the stronger UX sense.

5. Batch operation progress UI: largely missing outside node upgrade
- Tunnel batch delete/redeploy: only loading spinner/toast + full reload, no per-item progress/result panel.
- Forward batch actions: summarized via toast and optional refresh, but no visible progress timeline/progress list.
- User batch tunnel assignment: no progress UI beyond loading state.

6. Search/filter instant response: mixed
- Nodes/tunnels/forwards are instant client-side.
- Users are not fully instant:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
  - `loadUsers()` is server-driven and tied to `useEffect([pagination.current, pagination.size, searchKeyword])`
  - Enter key also manually calls `handleSearch()`
- So user search is AJAX but not purely local/instant in the same way.

c) Specific file paths and functions to touch for an implementation plan

Primary targets

1. Dashboard auto-refresh
- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard/use-dashboard-data.ts`
  - `useDashboardData()`
  - extract `loadPackageData()` / `loadAnnouncement()` into stable callbacks
  - add polling or visibility/focus-based refetch
- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/dashboard.tsx`
  - if adding manual refresh indicator/button, this is the page entry
- API source already exists:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/api/index.ts`
  - `getUserPackageInfo()`, `getAnnouncement()`

2. Node realtime hardening / fallback
- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-realtime.ts`
  - `useNodeRealtime()`
  - retry policy, reconnect strategy, possible fallback refresh trigger
- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
  - `handleWebSocketMessage()`
  - `loadNodes()`
  - `handleSubmit()`
  - `confirmDelete()`
  - `handleBatchDelete()`

3. Replace whole-list reloads with local/partial updates
- Tunnels:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/tunnel.tsx`
  - `loadData()`
  - `handleSubmit()`
  - `confirmDelete()`
  - `handleBatchDelete()`
  - `handleBatchRedeploy()`
- Forwards:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward.tsx`
  - `loadData()`
  - `handleSubmit()`
  - `confirmDelete()`
  - `handleServiceToggle()`
  - `handleBatchDelete()`
  - `handleBatchToggleService()`
  - `handleBatchRedeploy()`
  - `handleBatchChangeTunnel()`
- Users:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
  - `loadUsers()`
  - `handleSubmitUser()`
  - `handleConfirmDelete()`
  - `loadUserTunnels()`
  - `handleBatchAssignTunnel()`
  - `handleUpdateTunnel()`
  - `handleConfirmRemoveTunnel()`
  - `handleConfirmResetFlow()`
  - `handleConfirmResetTunnelFlow()`

4. Batch progress/result UX
- Nodes already have a model to copy:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node.tsx`
  - `upgradeProgress`
  - websocket `upgrade_progress`
- Forward batch abstraction:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/forward/batch-actions.ts`
  - likely extend return shape if backend can expose richer progress/events
- API endpoints involved:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/api/index.ts`
  - `batchDeleteForwards()`
  - `batchPauseForwards()`
  - `batchResumeForwards()`
  - `batchRedeployForwards()`
  - `batchChangeTunnel()`
  - `batchDeleteTunnels()`
  - `batchRedeployTunnels()`
  - `batchDeleteNodes()`
  - `batchUpgradeNodes()`

5. Search/filter behavior normalization
- `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/user.tsx`
  - `loadUsers()`
  - `handleSearch()`
  - search input around lines ~718+
- Nodes/tunnels/forwards already have memo-based client filtering and are the pattern to follow.

d) Notable risks / edge cases

1. Dashboard polling could spam toasts
- `checkExpirationNotifications()` runs inside package load flow.
- If polling is added naively, expiration toasts could repeat or localStorage notification keys could churn unexpectedly.

2. Dashboard chart semantics
- `statisticsFlows` appears to be a snapshot list, not a stream API.
- Frequent polling may redraw aggressively and may need dedupe/staleness handling.

3. Node websocket auth/security
- Realtime URL sends token in query string (`secret=${getToken()}`) in:
  - `/Users/sagit/.local/share/opencode/worktree/13650be91caa3a9e08a2e63127fef62757658384/quiet-canyon/vite-frontend/src/pages/node/use-node-realtime.ts`
- Any changes should be careful not to break backend expectations.

4. Realtime/local state merge complexity
- `loadNodes()` normalizes nodes and clears `systemInfo`.
- If partial refetch is introduced, merging fetched node metadata with live websocket state must avoid wiping online metrics/progress.

5. Batch APIs may not provide granular progress
- Current batch helpers mostly return summary counts, not per-item progress.
- True progress UI may require backend support, not only frontend work.

6. Forward toggle consistency
- `handleServiceToggle()` optimistically flips `serviceRunning` and later patches `status`.
- If backend returns partial failure or delayed actual state, UI may drift until a refresh.

7. User search behavior currently depends on backend pagination/search
- Moving to fully instant local filtering may conflict with server-side pagination semantics and large datasets.

Bottom line
- Already present: async modal CRUD, no browser reloads, strong node realtime, optimistic forward toggle, instant search/filter on node/tunnel/forward pages.
- Missing/partial for #276: dashboard traffic auto-refresh, consistent partial/local state updates after CRUD, batch progress UI outside node upgrade, and more unified instant-search UX on the user page.
