# Tasks: Superset-Style UX Redesign

**Input**: Design documents from `/specs/019-superset-ux-redesign/`
**Prerequisites**: plan.md ✅, spec.md ✅, research.md ✅, data-model.md ✅, contracts/ ✅

**Tests**: Not explicitly requested - implementation tasks only.

**Organization**: Tasks are grouped by user story to enable independent implementation and testing of each story.

## Format: `[ID] [P?] [Story] Description`

- **[P]**: Can run in parallel (different files, no dependencies)
- **[Story]**: Which user story this task belongs to (e.g., US1, US2, US3)
- Include exact file paths in descriptions

## Path Conventions

- **Web app**: `backend/src/`, `frontend/src/`

---

## Phase 1: Setup (Shared Infrastructure)

**Purpose**: Create new directory structure and stores for layout state

- [x] T001 Create `frontend/src/lib/components/layout/` directory for shared layout components
- [x] T002 Create `frontend/src/lib/components/hubs/` directory for resource hub pages
- [x] T003 [P] Create `frontend/src/lib/stores/sidebar.js` with persistentStore pattern for sidebar state
- [x] T004 [P] Create `frontend/src/lib/stores/taskDrawer.js` with resourceTaskMap store
- [x] T005 [P] Create `frontend/src/lib/stores/activity.js` as derived store from taskDrawer

---

## Phase 2: Foundational (Blocking Prerequisites)

## Dependencies & Execution Order

### Phase Dependencies

- **Setup (Phase 1)**: No dependencies - can start immediately
- **Foundational (Phase 2)**: Depends on Setup completion - BLOCKS all user stories
- **User Stories (Phase 3-8)**: All depend on Foundational phase completion
  - US1, US2, US5 (P1) can proceed in parallel
  - US3, US4, US6 (P2) can proceed after P1 stories or in parallel
- **Polish (Phase 9)**: Depends on all desired user stories being complete

### User Story Dependencies

- **US1 (P1)**: Can start after Foundational - No dependencies on other stories
- **US2 (P1)**: Can start after Foundational - Uses stores from Setup
- **US5 (P1)**: Can start after Foundational - Uses TopNavbar from Foundational
- **US3 (P2)**: Can start after Foundational - Uses Task Drawer from US2
- **US4 (P2)**: Can start after Foundational - Uses Task Drawer from US2
- **US6 (P2)**: Can start after Foundational - Uses Sidebar from US1

### Parallel Opportunities

- T003, T004, T005 can run in parallel (different store files)
- T031, T032 can run in parallel (different backend files)
- T042 can run in parallel with T031
- T049 can run in parallel with other backend tasks
- T057, T058, T060, T061 can run in parallel (different concerns)

## Implementation Strategy

### MVP First (P1 Stories Only)

1. Complete Phase 1: Setup
2. Complete Phase 2: Foundational (CRITICAL - blocks all stories)
3. Complete Phase 3: User Story 1 (Sidebar Navigation)
4. Complete Phase 4: User Story 2 (Task Drawer)
5. Complete Phase 5: User Story 5 (Top Navbar)
6. **STOP and VALIDATE**: Test all P1 stories independently
7. Deploy/demo if ready

### Full Delivery (P1 + P2 Stories)

1. MVP First (above)
2. Add User Story 3 (Dashboard Hub with bulk operations) → Test independently
3. Add User Story 4 (Dataset Hub with bulk operations) → Test independently
4. Add User Story 6 (Settings) → Test independently
5. Complete Polish phase
6. Final validation

**Note**: US3 and US4 are now P1 priority due to bulk operations requirements for dashboards and datasets.
