## Phase 2: Row-Level Security & Multi-Tenancy Hardening

### Goal
Enforce tenant isolation at the database layer so even application bugs can't leak data across tenants.

### Tasks

1. **Apply RLS policies to the live database**
   - File: `scripts/setup-rls.sql` (already written)
   - Run via `docker exec` on the db container, or add to `docker-entrypoint.sh` after `prisma db push`
   - Every tenant-scoped table gets `ENABLE ROW LEVEL SECURITY` + a policy checking `current_setting('app.current_tenant_id')`

2. **Wire up the Prisma RLS client extension**
   - File: `src/lib/server/rls.ts` (already written but unused)
   - `forTenant(tenantId)` wraps queries in a transaction that does `SET LOCAL app.current_tenant_id = '<id>'`
   - `bypassRLS()` for site admin cross-tenant operations
   - Update all API routes and server load functions to use `forTenant(locals.tenant.id)` instead of raw `prisma`

3. **Create a shared helper for tenant-scoped DB access**
   - File: `src/lib/server/db.ts` — add `export function tenantDb(locals: App.Locals)` that returns `forTenant(locals.tenant!.id)`
   - All routes call `tenantDb(locals)` instead of importing `prisma` directly

4. **Test multi-tenant isolation**
   - Access via two different hostnames (two tenants auto-created)
   - Create boards on each — verify they don't appear on the other
   - Verify API endpoints can't fetch cross-tenant data by ID

### Acceptance Criteria
- All API routes use tenant-scoped Prisma client
- Direct SQL query with wrong tenant_id returns 0 rows
- Two separate hostnames show fully isolated data

---

## Phase 3: Roles & Permissions Enforcement

### Goal
Enforce GlobalRole (SITE_ADMIN, USER), TenantRole (ADMIN, MEMBER), and BoardMemberRole (OWNER, EDITOR, VIEWER) throughout the app.

### Tasks

1. **Create route guards**
   - File: `src/lib/server/guards.ts`
   - `requireAuth(locals)` — throws 401 if not logged in
   - `requireTenantAdmin(locals)` — throws 403 if not tenant ADMIN
   - `requireSiteAdmin(locals)` — throws 403 if not SITE_ADMIN
   - `requireBoardAccess(locals, boardId, minRole?)` — checks membership

2. **Apply guards to all API routes**
   - Board CRUD: owners can delete, editors can modify, viewers read-only
   - Column/Card CRUD: inherit from board membership
   - Already partially done in routes — audit each for consistency

3. **Public board anonymous access**
   - `GET /api/boards/[boardId]` — if `visibility === 'PUBLIC'`, allow without auth
   - Board view page server load — same check (already done, verify)
   - Board listing — anonymous users see only PUBLIC boards (already done, verify)

4. **Board member management UI**
   - File: `src/routes/boards/[boardId]/members/+page.svelte`
   - API: `POST/DELETE /api/boards/[boardId]/members`
   - Add members by email (must be registered on same tenant)
   - Change member role (OWNER/EDITOR/VIEWER)
   - Remove members
   - Only OWNER can manage members

5. **Tenant admin panel (basic)**
   - File: `src/routes/admin/+page.svelte` (guarded by tenantRole === 'ADMIN')
   - List all users in tenant, change their tenantRole
   - List all boards in tenant

### Acceptance Criteria
- VIEWER cannot create/edit/delete cards or columns
- Non-members cannot access PRIVATE boards
- Anonymous can view PUBLIC boards but not edit
- Board owner can add/remove/change member roles
- Tenant admin can see all boards and manage users

---

## Phase 4: Rich Card Features

### Goal
Cards get labels, categories, markdown descriptions, due dates, assignees, checklists, comments, and file attachments.

### Tasks

1. **Tags/Labels system**
   - API: `CRUD /api/tags` (tenant-scoped)
   - API: `POST/DELETE /api/boards/[boardId]/columns/[columnId]/cards/[cardId]/labels`
   - UI: Color picker for tag creation, label pills on cards
   - Card modal: add/remove labels section
   - File: `src/lib/components/TagPicker.svelte`

2. **Categories (board grouping)**
   - API: `CRUD /api/categories` (tenant-scoped)
   - Board listing page: group boards by category, filter dropdown
   - Board create/edit: optional category selector

3. **Markdown description editor**
   - Card modal: replace plain textarea with markdown editor
   - Use `marked` (already installed) for rendering
   - Toggle between edit and preview modes
   - File: `src/lib/components/MarkdownEditor.svelte`

4. **Due dates with urgency indicators**
   - Card modal: date picker input for due date
   - Card thumbnail: colored badge (green = future, yellow = soon, red = overdue)
   - API: PATCH card with `dueDate` field (already supported)
   - Use `date-fns` (already installed) for relative time

5. **Assignees**
   - Card modal: dropdown to assign board members
   - API: `POST/DELETE /api/boards/[boardId]/columns/[columnId]/cards/[cardId]/assignees`
   - Show avatar circles on card thumbnails (already rendering if present)

6. **Checklists**
   - Card modal: add checklists with items, toggle completion
   - API: `CRUD /api/boards/[boardId]/columns/[columnId]/cards/[cardId]/checklists`
   - API: `CRUD .../checklists/[checklistId]/items`
   - Progress bar on card thumbnail showing X/Y items done
   - File: `src/lib/components/Checklist.svelte`

7. **Comments**
   - Card modal: comment list + add comment form (markdown)
   - API: `CRUD /api/boards/[boardId]/columns/[columnId]/cards/[cardId]/comments`
   - Show author name, avatar, timestamp, edit/delete own comments
   - File: `src/lib/components/CommentList.svelte`

8. **File attachments**
   - Card modal: drag-drop or file picker to upload
   - API: `POST /api/boards/[boardId]/columns/[columnId]/cards/[cardId]/attachments` (multipart)
   - API: `GET /api/attachments/[id]` to download
   - Store in `/app/uploads` Docker volume (already mounted)
   - Show file list with name, size, download link
   - File: `src/lib/components/Attachments.svelte`

### Acceptance Criteria
- All features visible in the card modal
- Labels appear as colored pills on board view cards
- Due date badge with color coding
- Checklist progress bar on card thumbnails
- Comments with markdown rendering
- File upload/download working via Docker volume

---

## Phase 5: Real-Time Updates (Socket.IO)

### Goal
Multiple users viewing the same board see live updates: card moves, new cards, column changes, comments, presence.

### Tasks

1. **Socket.IO server integration**
   - File: `server.js` (production) — already has basic setup
   - File: `src/socket/index.ts` — auth middleware, room management (already written)
   - Add Vite dev middleware for Socket.IO (simple HTTP server attach in dev)

2. **Client-side socket connection**
   - File: `src/lib/stores/socket.ts` (already written)
   - Connect on app load (layout), disconnect on unload
   - Join board room when entering board view, leave when exiting

3. **Broadcast events from API routes**
   - After every write operation (create/update/delete), emit to the board room
   - Events: `card:created`, `card:updated`, `card:moved`, `card:deleted`, `column:created`, `column:updated`, `column:moved`, `column:deleted`, `comment:created`, etc.
   - File: `src/lib/server/realtime.ts` — helper `broadcast(boardId, event, data)`
   - Import and call from each API route's POST/PATCH/DELETE handler
   - In dev, use a global event emitter; in prod, use Socket.IO directly

4. **Client-side event handlers on board view**
   - File: `src/routes/boards/[boardId]/+page.svelte`
   - Listen for socket events and update local `columns` state
   - Handle: new cards appearing, cards moving, columns reordering, deletions
   - Ignore events triggered by the current user (deduplicate via socket ID)

5. **Optimistic UI with rollback**
   - Card moves: update local state immediately, send API request
   - If API fails: revert to previous state, show toast error
   - Other users see the final state from the socket event

6. **Presence indicators**
   - Track which users are viewing a board (via socket room)
   - Show avatar dots in board header: "Also viewing: Alice, Bob"
   - Events: `user-joined`, `user-left` (already emitted in socket/index.ts)

### Acceptance Criteria
- Open two browser tabs on the same board
- Move a card in tab A → appears in tab B within 1 second
- Add a column in tab B → appears in tab A
- Presence shows both tabs' users
- If API fails, optimistic update rolls back

---

## Phase 6: Activity Log & Notifications

### Goal
Track all significant actions, provide activity feeds, and notify users of relevant events.

### Tasks

1. **Activity logging service**
   - File: `src/lib/server/activity.ts`
   - `logActivity(boardId, userId, action, metadata?, cardId?)` — writes to `activities` table
   - Actions: `board.created`, `card.created`, `card.moved`, `card.updated`, `card.deleted`, `column.created`, `column.deleted`, `comment.added`, `member.added`, `member.removed`
   - Call from every API route after successful writes

2. **Activity feed API**
   - `GET /api/boards/[boardId]/activity` — paginated, returns recent activity for a board
   - `GET /api/boards/[boardId]/columns/[columnId]/cards/[cardId]/activity` — card-specific
   - Include user name, action description, timestamp, link

3. **Board activity sidebar**
   - File: `src/lib/components/ActivityFeed.svelte`
   - Toggleable sidebar on board view showing recent actions
   - "Alice moved 'Fix login bug' from To Do to In Progress — 5 min ago"

4. **Card activity in modal**
   - Show activity timeline in card modal below comments
   - Interleave comments and activity chronologically

5. **Notification generation**
   - File: `src/lib/server/notifications.ts`
   - Generate notifications for: assigned to card, mentioned in comment (@username), due date approaching (daily cron or on-access check)
   - Write to `notifications` table

6. **Notification UI**
   - Bell icon in navbar with unread count badge
   - Dropdown showing recent notifications
   - Click to navigate to relevant card/board
   - Mark as read (individual + mark all)
   - API: `GET /api/notifications`, `PATCH /api/notifications/[id]` (mark read), `POST /api/notifications/read-all`
   - File: `src/lib/components/NotificationBell.svelte`

7. **Real-time notification push**
   - When a notification is created, emit via Socket.IO to the target user
   - User's socket joins `user:<userId>` room on connect
   - Bell icon updates live without page refresh

### Acceptance Criteria
- Board sidebar shows chronological activity
- Card modal shows activity + comments interleaved
- Bell icon shows unread notification count
- Assigning a user to a card generates a notification
- Notifications appear in real-time via socket

---

## Phase 7: Search, Filters & Templates

### Goal
Find cards quickly with filters and search. Create boards from templates.

### Tasks

1. **Board-level card filters**
   - Filter bar above columns: by label, assignee, due date range
   - Client-side filtering (hide non-matching cards, don't remove from state)
   - File: `src/lib/components/BoardFilters.svelte`
   - Filter state stored in URL search params for shareability

2. **Global search with PostgreSQL full-text search**
   - Add `tsvector` column to `cards` table (or use generated column)
   - Create GIN index on the tsvector
   - Migration: `ALTER TABLE cards ADD COLUMN search_vector tsvector GENERATED ALWAYS AS (to_tsvector('english', coalesce(title,'') || ' ' || coalesce(description,''))) STORED;`
   - `CREATE INDEX cards_search_idx ON cards USING gin(search_vector);`
   - API: `GET /api/search?q=<query>` — returns matching cards with board/column info
   - UI: Search bar in navbar, results dropdown with card titles + board names
   - File: `src/lib/components/SearchBar.svelte`

3. **Board templates**
   - System templates: "Basic Kanban" (To Do, In Progress, Done), "Scrum Sprint" (Backlog, Sprint, In Review, Done), "Bug Tracker" (New, Confirmed, In Progress, Resolved, Closed)
   - Tenant templates: save any board as a template
   - API: `GET /api/templates`, `POST /api/templates` (save board as template), `POST /api/boards?templateId=<id>` (create from template)
   - Template data stored as JSON in `board_templates.template` column
   - Board creation UI: "Start from template" option
   - Seed system templates in `prisma/seed.ts`

4. **Archive/unarchive UI**
   - Board listing: toggle to show archived boards
   - Board header: archive/unarchive button (OWNER only)
   - Card: archive button in modal (already `archived` field in schema)
   - Archived cards hidden from board view (already filtered in queries)
   - Board view: toggle to show archived cards (grayed out)

### Acceptance Criteria
- Filter cards by label → only matching cards visible
- Search "login" → finds cards with "login" in title or description
- Create board from "Basic Kanban" template → 3 columns pre-created
- Archive a card → disappears from board, visible in archive view

---

## Phase 8: Polish & UX

### Goal
Make the app feel production-quality with dark mode, keyboard shortcuts, responsive design, loading states, and accessibility.

### Tasks

1. **Dark mode**
   - Tailwind v4 dark mode via `class` strategy
   - Toggle button in navbar (sun/moon icon)
   - Persist preference in localStorage + cookie (for SSR)
   - File: `src/lib/stores/theme.ts`
   - Update `app.css` with dark variants for custom colors
   - `<html>` element gets `class="dark"` from layout

2. **Keyboard shortcuts**
   - `n` — new card (in focused column)
   - `Escape` — close modal/cancel edit
   - `b` — back to boards
   - `/` — focus search bar
   - `?` — show keyboard shortcuts help modal
   - File: `src/lib/components/KeyboardShortcuts.svelte`
   - Register in layout, context-aware (don't trigger in input fields)

3. **Responsive / mobile design**
   - Board view: horizontal scroll on mobile (already works with overflow-x)
   - Column width: responsive (narrower on small screens)
   - Card modal: full-screen on mobile
   - Navbar: hamburger menu on mobile
   - Board listing: single column grid on mobile

4. **Loading skeletons**
   - Board listing: card-shaped skeleton placeholders
   - Board view: column skeleton placeholders
   - Card modal: skeleton for async-loaded details
   - File: `src/lib/components/Skeleton.svelte`

5. **Toast notifications**
   - Success/error toasts for user actions (card created, error saving, etc.)
   - Auto-dismiss after 3–5 seconds
   - Stack in bottom-right corner
   - File: `src/lib/components/Toast.svelte`, `src/lib/stores/toasts.ts`

6. **Error handling**
   - Global error page: `src/routes/+error.svelte`
   - API error responses: consistent JSON `{ error: string }` format
   - Client-side fetch wrapper with automatic error toast

7. **Accessibility**
   - ARIA labels on all icon-only buttons (partially done)
   - Keyboard navigation for drag-and-drop (arrow keys to move cards)
   - Focus management in modals (trap focus, restore on close)
   - Screen reader announcements for drag-and-drop results

### Acceptance Criteria
- Dark mode toggles and persists across sessions
- All pages usable on a 375px mobile screen
- Keyboard shortcuts work (test: press `/` → search focuses)
- Loading skeletons appear on slow connections
- Toasts appear for create/delete/error actions

---

## Phase 9: Admin & DevOps

### Goal
Admin dashboards for site-wide and per-tenant management. Production readiness.

### Tasks

1. **Site Admin dashboard**
   - Route: `src/routes/admin/site/+page.svelte` (guarded: SITE_ADMIN only)
   - Cross-tenant statistics: total tenants, users, boards, cards
   - Tenant list with user counts, board counts, created date
   - Create/edit/delete tenants
   - Impersonate user (login as any user for debugging)
   - Uses `bypassRLS()` Prisma client

2. **Tenant Admin dashboard**
   - Route: `src/routes/admin/+page.svelte` (guarded: tenantRole ADMIN)
   - Tenant settings: name, allowed domains
   - User management: list, change roles, deactivate
   - Tag management: create/edit/delete tenant-scoped tags
   - Category management: create/edit/delete categories
   - Board overview: all boards with member counts

3. **Health check endpoint**
   - Route: `src/routes/api/health/+server.ts`
   - Returns `{ status: 'ok', db: true/false, uptime: seconds }`
   - Check DB connectivity with a simple query
   - Used by Docker HEALTHCHECK and monitoring

4. **Structured logging**
   - Replace `console.log` with a logger (pino or simple structured wrapper)
   - Log format: JSON with timestamp, level, message, metadata
   - Request logging middleware in hooks.server.ts (method, path, status, duration)

5. **Rate limiting**
   - In-memory rate limiter for auth endpoints (login, register)
   - File: `src/lib/server/ratelimit.ts`
   - 10 attempts per minute per IP for login
   - 5 registrations per hour per IP
   - Return 429 Too Many Requests

6. **Docker health check**
   - Add `HEALTHCHECK` to Dockerfile pointing at `/api/health`
   - Update `docker-compose.yml` with healthcheck for app service

7. **Backup documentation**
   - File: `docs/backup.md`
   - PostgreSQL: `pg_dump` command for the kanban database
   - Uploads volume: `docker cp` or volume backup
   - Restore procedure

### Acceptance Criteria

## Implementation Order Recommendation

Phases can be partially parallelized:
- **Phase 2** first (RLS) — foundational security
- **Phase 3** next (Roles) — needed before multi-user features
- **Phase 4** (Rich Cards) — the biggest feature payload, can start during Phase 3
- **Phase 5** (Real-Time) — depends on Phase 4 for full value
- **Phase 6** (Activity/Notifications) — depends on Phase 5
- **Phase 7** (Search/Filters/Templates) — independent, can be done anytime after Phase 4
- **Phase 8** (Polish) — do alongside or after feature phases
- **Phase 9** (Admin/DevOps) — can start admin panels during Phase 3, finish last
