# Phase 5: Board, Section & Widget System

**Status:** ✅ Complete
**Parent plan:** [PLAN.md](./PLAN.md)
**Domain:** fullstack

## Objective
Build the board/section/widget system — the core UI of the dashboard. Implement CRUD APIs, the board view page with collapsible sections and app widgets in a responsive grid, and the board editor.

## Tasks

- [x] Task 1: Create `src/routes/api/boards/+server.ts` — GET (list, filtered by permissions), POST
- [x] Task 2: Create `src/routes/api/boards/[id]/+server.ts` — GET, PATCH, DELETE
- [x] Task 3: Create `src/routes/api/boards/[id]/sections/+server.ts` — GET, POST
- [x] Task 4: Create `src/routes/api/boards/[id]/sections/[sid]/+server.ts` — GET, PATCH, DELETE
- [x] Task 5: Create `src/routes/api/boards/[id]/sections/[sid]/widgets/+server.ts` — GET, POST, PATCH, DELETE
- [x] Task 6: Create `src/routes/boards/+page.server.ts` — load board list
- [x] Task 7: Create `src/routes/boards/+page.svelte` — board list page
- [x] Task 8: Create `src/routes/boards/[boardId]/+page.server.ts` — load board with sections, widgets, app data
- [x] Task 9: Create `src/routes/boards/[boardId]/+page.svelte` — board view page
- [x] Task 10: Create `src/routes/boards/[boardId]/edit/+page.server.ts` — board editor data + actions
- [x] Task 11: Create `src/routes/boards/[boardId]/edit/+page.svelte` — board editor page
- [x] Task 12: Create `src/lib/components/board/Board.svelte` — board container
- [x] Task 13: Create `src/lib/components/board/BoardHeader.svelte` — board title, description, actions
- [x] Task 14: Create `src/lib/components/board/BoardCard.svelte` — board card for list view
- [x] Task 15: Create `src/lib/components/section/Section.svelte` — section container
- [x] Task 16: Create `src/lib/components/section/SectionHeader.svelte` — section title with collapse toggle
- [x] Task 17: Create `src/lib/components/section/SectionCollapsible.svelte` — collapsible wrapper
- [x] Task 18: Create `src/lib/components/widget/AppWidget.svelte` — app widget displaying icon, name, status
- [x] Task 19: Create `src/lib/components/widget/WidgetContainer.svelte` — generic widget wrapper
- [x] Task 20: Create `src/lib/components/widget/WidgetGrid.svelte` — responsive grid layout for widgets

## Files to Modify/Create
- `src/routes/api/boards/+server.ts`
- `src/routes/api/boards/[id]/+server.ts`
- `src/routes/api/boards/[id]/sections/+server.ts`
- `src/routes/api/boards/[id]/sections/[sid]/+server.ts`
- `src/routes/api/boards/[id]/sections/[sid]/widgets/+server.ts`
- `src/routes/boards/+page.server.ts`
- `src/routes/boards/+page.svelte`
- `src/routes/boards/[boardId]/+page.server.ts`
- `src/routes/boards/[boardId]/+page.svelte`
- `src/routes/boards/[boardId]/edit/+page.server.ts`
- `src/routes/boards/[boardId]/edit/+page.svelte`
- `src/lib/components/board/*.svelte`
- `src/lib/components/section/*.svelte`
- `src/lib/components/widget/*.svelte`

## Acceptance Criteria
- Boards can be created, listed, viewed, edited, deleted
- Sections within boards support CRUD and ordering
- Widgets within sections support CRUD and ordering
- Board view renders sections with collapsible behavior
- App widgets show icon, name, status dot, and link to app URL
- Responsive grid adapts to screen size
- Default board is accessible from root page

## Notes
- MVP supports only AppWidget type; schema should have `type` field for future widget types
- Widget config is JSON: `{ appId: string }` for AppWidget
- Section collapse uses Svelte `slide` transition
- Board editor is a form-based editor (drag-and-drop is post-MVP Phase 2)
- Permission filtering on board list uses permissionService
- Big Bang: functional but minimally styled until Phase 7

## Review Checklist
- [x] All tasks completed
- [x] Code follows project conventions
- [x] No unintended side effects
- [ ] Build passes
- [ ] Tests pass (new + existing)

## Handoff to Next Phase

Phase 5 is complete. All board, section, and widget CRUD APIs are implemented with permission-based filtering (admin sees all, regular users see permitted boards, guests see guest-accessible boards only). The board view page loads the full board hierarchy (board -> sections -> widgets -> app + status) via `boardService.findBoardById`. The board editor provides form-based management of board properties, sections (add/delete), and widgets (add app widgets from a dropdown, remove). All Svelte components use runes mode and follow existing patterns:
- `Board.svelte` renders sections in order
- `Section.svelte` uses `SectionHeader` (chevron toggle) + `SectionCollapsible` (Svelte `slide` transition)
- `WidgetGrid.svelte` uses a responsive CSS grid (2/3/4 cols)
- `AppWidget.svelte` displays app icon, name, and health status badge (reuses `AppHealthBadge`)
- `BoardCard.svelte` shows board summary with section count, default/guest badges

Key files for Phase 6 (Admin Panel):
- Board API routes at `/api/boards/**` are ready for admin operations
- Permission checking via `permissionService.checkPermission()` is integrated into all write operations
- Board editor at `/boards/[boardId]/edit` is functional for admin use
