-ensured localStorage doesnt exist on server, but next js runs 'use client' components on the server first during SSR. Checked 'typeof window !== 'undefined' before accessing localStorage so the server gets a safe fallback and the real value is only read in browser Task notification: The bell badge and task panel had no way to permanently delete tasks — they lived in server memory until auto-cleaned after an hour — so we added real DELETE API endpoints on the backend, per-row × dismiss buttons, and a "Clear all" button that remove tasks immediately and re-render the count badge dynamically.

System color change: The Console Status button and "Active" connector badge used hardcoded dark-mode zinc/foreground colors that broke in light mode, so we swapped them for semantic Tailwind tokens (bg-muted, text-muted-foreground, border-border) that automatically adapt to whichever theme is active.

Summary by CodeRabbit

  • New Features

    • Added options to delete individual completed or failed tasks, or clear all terminal tasks.
    • Task notifications now show task counts, expandable progress details, and deletion controls.
    • Added a “Clear all” action when terminal tasks are available.
    • The header notification badge displays the number of tasks, up to 99+.
    • Deletion now distinguishes unavailable tasks from tasks still in progress.
  • Bug Fixes

    • Improved keyboard and click interactions for expanding task error details.
  • Style

    • Updated connector and console status styling to better support themes and muted states.

Walkthrough

The change adds authenticated deletion for terminal tasks, updates the task notification menu with deletion and expansion controls, replaces the header notification dot with a task-count badge, and applies theme-based styling to selected status controls.

Changes

Terminal task management

Layer / File(s) Summary
Task deletion backend
src/models/tasks.py, src/services/task_service.py, src/api/tasks.py, src/app/routes/internal.py
TaskService returns explicit deletion results and deleted task IDs. DELETE routes expose distinct responses for missing and in-progress tasks.
Client deletion mutations
frontend/app/api/mutations/useDeleteTaskMutation.ts
React Query mutations call the DELETE endpoints and update the cached task list after successful deletion.
Notification controls and terminal task rendering
frontend/components/task-notification-menu.tsx, frontend/components/task-panel-header.tsx
The menu supports individual deletion, clear-all deletion, expandable terminal-task rows, progress details, and terminal-task-based empty-state rendering.
Task error expansion interaction
frontend/components/task-error-content.tsx
Failed-task headers support click and keyboard expansion. Task-detail actions stop event propagation.
Task count notification
frontend/components/header.tsx
The header displays a task-count badge, capped at 99+, instead of the previous notification dot. Console-problem state no longer drives the badge.

Frontend theme and tooling updates

Layer / File(s) Summary
Theme-based status styling
frontend/app/settings/_components/connector-card.tsx, frontend/components/console-status/button.tsx
Connector and console-status styling now uses muted and theme-based color tokens.
Frontend pre-commit environment
frontend/.husky/pre-commit
The pre-commit hook sets NVM_DIR and sources nvm.sh when available instead of using a machine-specific Node.js path.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to ebbbe

The task-notification overhaul adds persistent deletion and expandable task details, but the current implementation still has bounded correctness, cleanup-retry, event-loop blocking, and interaction issues that can cause failed deletes, delayed task handling, or unexpectedly closing error details. These should be fixed or explicitly accepted before merge.

task row and the additional control identified in the comment, to include
focus-visible:opacity-100 and a visible focus indicator alongside their existing
hover styles; preserve their current click behavior and layout.

- Around line 104-122: Update TaskService.delete_task and the delete_task
handler to distinguish an absent task from an existing non-terminal task: return
404 only for absence and 409 Conflict for tasks still in progress, while
preserving the successful deletion response. Add typed success and error
response models to the handler registration, and verify the existing dependency
injection through get_task_service and get_current_user in src/dependencies.py.

In `@src/services/task_service.py`:
- Around line 1532-1548: Update delete_all_terminal_tasks to include anonymous
shared terminal tasks in the same visibility scope as get_all_tasks, while
preserving user-specific task deletion. Ensure the client-side clear-all flow
only removes tasks confirmed as deleted by the server, so shared tasks that
remain are not removed from the React Query cache.

1572-1575: 🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift

Do not run bulk cleanup on the event loop.

delete_all_terminal_tasks() performs synchronous filesystem cleanup, and src/api/tasks.py calls it directly from an async DELETE handler. A large task set can block the event loop and delay unrelated requests. Make bulk cleanup asynchronous or offload filesystem work while preserving task-store mutation order.

1556-1557: 🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Retain failed cleanup for a later retry.

_cleanup_upload_temp_files(force=True) keeps a path when safe_unlink cannot remove it. These lines then delete the task and its store entry unconditionally. The store no longer retains the task needed for periodic cleanup, so the staged file becomes orphaned. Requeue failed cleanup or preserve the task until all staged paths are removed.

Limit accordion activation to the header.

When showHeader is true, clicks on expanded file-error cards bubble to the outer <div> and collapse the panel. Move the click and keyboard handlers to the header only. Add a regression test that verifies aria-expanded remains true after clicking an error card.

!res.ok is true for 404 and 409. throw stops onSuccess, so the row is not removed from the cache. React Query stores the error on the mutation.
Nobody reads that error. There is no onError, no toast, and the caller is fire-and-forget

wait so what should be addressed here? am I removing the throw Error so onSuccess remains in cache?

fix suggestion:
if (res.status === 404) return; // already gone and still drop from cache
if (!res.ok) {
const body = await res.json().catch(() => ({}));
throw new Error(body.error || "Failed to delete task");
}

res.json() parses the HTTP body. That can fail when the body is empty, not JSON, or already consumed. .catch(() => ({})) turns that into an empty object so the next line can still do body.error || "Failed to delete task" without crashing.
