+# Implementation Tasks
+
+## 1. Setup and Configuration
+
+- [ ] 1.1 Load JetBrains Mono font from Google Fonts in `src/app/layout.tsx` (add to head with weights 400, 500, 700)
+- [ ] 1.2 Update `next.config.js` to enable standalone output mode (`output: 'standalone'`)
+- [ ] 1.3 Verify all existing features work (run dev server, test line drawing, label placement, delete tool)
+
+## 2. API Extensions for Bulk Operations
+
+- [ ] 2.1 Read existing `src/app/api/annotations/route.ts` DELETE handler
+- [ ] 2.2 Add query parameter parsing in DELETE handler (`type` and `all` params from `request.nextUrl.searchParams`)
+- [ ] 2.3 Add conditional WHERE clause logic: if `type` param exists, filter by `label_type IN (comma-separated types)`, if `all=true` delete everything, else return 400 error
+- [ ] 2.4 Update return value to include count: `{ success: true, deleted: <count> }` using `result.length` from Drizzle delete operation
+- [ ] 2.5 Test bulk delete via curl: `curl -X DELETE "http://localhost:3000/api/annotations?type=break_up"` (verify count returned)
+- [ ] 2.6 Create new file `src/app/api/health/route.ts` with GET handler returning `{ status: 'ok', timestamp: Date.now() }`
+- [ ] 2.7 Add optional database check in health endpoint: if `?check=db` query param exists, attempt simple `SELECT 1` query and return 503 on failure
+- [ ] 2.8 Test health endpoint: `curl http://localhost:3000/api/health` (verify 200 response)
+
+## 3. Hacker Theme - CSS Variables and Tailwind
+
+- [ ] 3.1 Read current `src/app/globals.css` and note existing CSS variable names
+- [ ] 3.2 Replace CSS variable values in `:root` with hacker theme colors: `--background: 120 100% 4%` (#0a0e0a), `--foreground: 120 100% 50%` (#00ff41), `--primary: 120 100% 50%`, `--destructive: 348 100% 50%` (#ff0040), `--border: 120 100% 10%` (#003311), map all other variables to theme equivalents
+- [ ] 3.3 Update body font-family in `globals.css` to: `font-family: 'JetBrains Mono', 'Fira Code', 'Courier New', monospace;`
+- [ ] 3.4 Add custom selection styling in `globals.css`: `::selection { background: rgba(0, 255, 65, 0.4); color: #00ff41; }`
+- [ ] 3.5 Add custom scrollbar styles in `globals.css`: `::-webkit-scrollbar { width: 8px; }`, `::-webkit-scrollbar-track { background: #003311; }`, `::-webkit-scrollbar-thumb { background: #00ff41; border-radius: 4px; }`
+- [ ] 3.6 Read `tailwind.config.ts` and locate `theme.extend.colors` object

+- [ ] 3.10 Add keyframes to Tailwind config: `'glow-pulse': { '0%, 100%': { boxShadow: '0 0 15px #00ff41' }, '50%': { boxShadow: '0 0 30px #00ff41, 0 0 50px rgba(0,255,65,0.5)' } }`, `'flicker': { '0%, 100%': { opacity: '1' }, '50%': { opacity: '0.8' } }`
+- [ ] 3.11 Add animations to Tailwind config: `'glow-pulse': 'glow-pulse 2s ease-in-out infinite'`, `'flicker': 'flicker 0.1s ease-in-out'`
+- [ ] 3.12 Test theme in browser: verify green text, black background, monospace font on all elements
+
+## 4. Hacker Theme - Component Styling
+
+- [ ] 4.1 Read `src/components/Toolbox.tsx` and identify button elements
+- [ ] 4.2 Update button hover states in Toolbox to add glow effect: add `hover:shadow-glow` class to all Button components
+- [ ] 4.3 Update active tool buttons in Toolbox: when `activeTool` matches, add `animate-glow-pulse` class
+- [ ] 4.4 Update input field styling (search input in label list, if exists): add `focus:shadow-glow-sm focus:border-matrix` classes
+- [ ] 4.5 Read `src/components/ui/button.tsx` and add destructive variant glow: in destructive variant, change hover shadow to red: `hover:shadow-[0_0_15px_#ff0040]`
+- [ ] 4.6 Test button styling: hover over buttons (should glow green), click to activate tool (should pulse), hover delete button (should glow red)
+
+## 5. Label Management - State and Selection
+
+- [ ] 5.1 Read `src/app/page.tsx` and locate existing state declarations (activeTool, selectedColor, etc.)
+- [ ] 5.2 Add new state in page.tsx: `const [selectedLabelId, setSelectedLabelId] = useState<number | null>(null)`
+- [ ] 5.3 Pass selectedLabelId and setSelectedLabelId as props to CandleChart component
+- [ ] 5.4 Read `src/components/CandleChart.tsx` and locate marker creation code (where break_up/break_down markers are added)
+- [ ] 5.5 Add onClick handler to marker options: in marker creation config, add `onClick: () => props.onLabelSelect?.(annotation.id)`
+- [ ] 5.6 Update CandleChart props interface to accept `selectedLabelId: number | null`, `onLabelSelect: (id: number) => void`
+- [ ] 5.7 Wire up onLabelSelect in page.tsx: `onLabelSelect={(id) => setSelectedLabelId(id === selectedLabelId ? null : id)}`
+- [ ] 5.8 Add visual highlight for selected marker: when rendering markers, if `annotation.id === selectedLabelId`, set marker size to 1.5x and add glow effect (modify marker shape/color options)
+- [ ] 5.9 Test label selection: click on break_up arrow (should highlight), click again (should deselect), click different marker (should switch selection)
+
+## 6. Label Management - Keyboard Delete
+
+- [ ] 6.1 Read `src/app/page.tsx` and locate any existing keyboard event handlers
+- [ ] 6.2 Add global keyboard handler in page.tsx useEffect: `window.addEventListener('keydown', handleKeyDown)`
+- [ ] 6.3 Implement handleKeyDown function: if `e.key === 'Delete' || e.key === 'Backspace'`, check if `selectedLabelId !== null`
+- [ ] 6.4 In handleKeyDown, when Delete pressed with selected label: call `fetch('/api/annotations/' + selectedLabelId, { method: 'DELETE' })`
+- [ ] 6.5 After successful delete, call chart refresh method and reset `setSelectedLabelId(null)`
+- [ ] 6.6 Add cleanup in useEffect: `return () => window.removeEventListener('keydown', handleKeyDown)`
+- [ ] 6.7 Test keyboard delete: select a label marker, press Delete key (marker should disappear), verify database updated
+
+## 7. Label Management - Sidebar List UI Structure
+
+- [ ] 7.1 Read `src/components/Toolbox.tsx` and locate the export button section (bottom of component)
+- [ ] 7.2 Import Collapsible components from shadcn/ui: check if `src/components/ui/collapsible.tsx` exists, if not install via `npx shadcn@latest add collapsible`
+- [ ] 7.3 Add state in Toolbox for collapsed state: `const [labelsExpanded, setLabelsExpanded] = useState(true)`
+- [ ] 7.4 Add new section above Export button: wrap in Collapsible component with `open={labelsExpanded}` and `onOpenChange={setLabelsExpanded}`
+- [ ] 7.5 Create section header button: "Label Annotations (X)" with ChevronDown/ChevronUp icon from lucide-react, clicking toggles `labelsExpanded`
+- [ ] 7.6 Inside Collapsible.Content, add container div with `className="max-h-96 overflow-y-auto space-y-2 p-2"`
+- [ ] 7.7 Add count display in header: calculate `breakUpCount` and `breakDownCount` from props.annotations filtered by `label_type`, display as "Break Up: X | Break Down: Y"
+- [ ] 7.8 Test collapsible: click header (should expand/collapse), verify smooth animation
+
+## 8. Label Management - Sidebar List Content
+
+- [ ] 8.1 Update Toolbox props to accept `annotations: Annotation[]`, `selectedLabelId: number | null`, `onLabelSelect: (id: number) => void`, `onLabelDelete: (id: number) => void`
+- [ ] 8.2 Pass annotations from page.tsx to Toolbox (retrieve from CandleChart or fetch directly in page.tsx)
+- [ ] 8.3 Filter annotations in Toolbox: `const labelAnnotations = annotations.filter(a => a.label_type === 'break_up' || a.label_type === 'break_down')`
+- [ ] 8.4 Sort labelAnnotations by timestamp descending: `labelAnnotations.sort((a, b) => b.timestamp - a.timestamp)`
+- [ ] 8.5 Map over labelAnnotations to render list items: each item in a div with border, padding, cursor-pointer, onClick calls onLabelSelect
+- [ ] 8.6 Format timestamp in each item: `new Date(timestamp * 1000).toLocaleString('en-US', { month: 'short', day: 'numeric', hour: '2-digit', minute: '2-digit' })`
+- [ ] 8.7 Add colored badge for label type: break_up shows "BREAK UP" in green bg, break_down shows "BREAK DOWN" in red bg
+- [ ] 8.8 Add delete button (trash icon) to each item: onClick calls `onLabelDelete(annotation.id)` with stopPropagation to prevent selection
+- [ ] 8.9 Highlight selected item: if `annotation.id === selectedLabelId`, add border-matrix and bg-matrix/10 classes
+- [ ] 8.10 Handle empty state: if labelAnnotations.length === 0, show message "No labels yet. Click Break Up or Break Down tools to add labels."
+- [ ] 8.11 Test list rendering: add several labels, verify they appear sorted by time, click to select, click delete button (should remove)
+
+## 9. Label Management - Search and Filter
+
+- [ ] 9.1 Add state for search in Toolbox: `const [searchText, setSearchText] = useState('')`
+- [ ] 9.2 Add state for filter in Toolbox: `const [filterType, setFilterType] = useState<'all' | 'break_up' | 'break_down'>('all')`
+- [ ] 9.3 Add search input above label list: Input component with placeholder "Search by timestamp...", value={searchText}, onChange={e => setSearchText(e.target.value)}
+- [ ] 9.4 Add filter dropdown above label list: Select or dropdown with options "All", "Break Up", "Break Down", value={filterType}, onChange={setFilterType}
+- [ ] 9.5 Apply filter to labelAnnotations: if filterType !== 'all', filter array by `a.label_type === filterType`
+- [ ] 9.6 Apply search to labelAnnotations: filter by formatted timestamp includes searchText (case-insensitive): `formattedTimestamp.toLowerCase().includes(searchText.toLowerCase())`
+- [ ] 9.7 Update count display to show filtered count: "Showing X of Y labels"
+- [ ] 9.8 Test search: type "Feb" in search (should filter to February dates), test filter: select "Break Up" (should show only break_up labels)
+
+## 10. Label Management - Delete All Labels Button
+
+- [ ] 10.1 Import Dialog components from shadcn/ui: check if `src/components/ui/dialog.tsx` exists, if not install via `npx shadcn@latest add dialog`
+- [ ] 10.2 Add state for confirmation dialog: `const [deleteAllDialogOpen, setDeleteAllDialogOpen] = useState(false)`
+- [ ] 10.3 Add "Delete All Labels" button below search/filter controls: Button with destructive variant, onClick opens dialog, disabled if labelAnnotations.length === 0
+- [ ] 10.4 Create Dialog component with AlertDialog pattern: AlertDialogTitle "Delete all label annotations?", AlertDialogDescription "This will remove all Break Up and Break Down markers. This cannot be undone."
+- [ ] 10.5 Add Cancel button in dialog: onClick closes dialog without action
+- [ ] 10.6 Add Confirm button in dialog: destructive variant, onClick calls API DELETE with type=break_up,break_down
+- [ ] 10.7 Implement delete all handler: `fetch('/api/annotations?type=break_up,break_down', { method: 'DELETE' })`, on success refresh annotations and close dialog
+- [ ] 10.8 Show toast notification after delete: use shadcn toast to display "> SUCCESS: Deleted all labels [X items]"
+- [ ] 10.9 Test delete all: add multiple labels, click Delete All Labels, confirm dialog (all should disappear), verify database emptied
+
+## 11. Toast Feedback System
+
+- [ ] 11.1 Install shadcn toast if not present: `npx shadcn@latest add toast`
+- [ ] 11.2 Read `src/components/ui/toast.tsx` and `src/hooks/use-toast.ts`
+- [ ] 11.3 Update toast styling in `toast.tsx`: add `font-mono` class, update border color to use matrix theme colors
+- [ ] 11.4 Import and add Toaster component in `src/app/layout.tsx` (add `<Toaster />` in body)
+- [ ] 11.5 Create useToast hook wrapper in components that need feedback: import `{ useToast } from '@/hooks/use-toast'`
+- [ ] 11.6 Add toast calls after successful operations: delete label → `toast({ title: "> SUCCESS", description: "Deleted label [1 item]" })`
+- [ ] 11.7 Add toast calls for errors: catch API errors → `toast({ title: "> ERROR", description: "Failed to delete [code: 500]", variant: "destructive" })`
+- [ ] 11.8 Test toast: perform delete operation (should see green success toast), cause error by disconnecting network (should see red error toast)
