- Created SpanRectanglePrimitive.ts implementing ISeriesPrimitive interface
- Implemented updateAllViews() with coordinate conversion from data-space to pixel-space
- Added semi-transparent rectangle rendering with configurable opacity
- Implemented label tag rendering above rectangles showing pattern names
- Added hitTest() for click detection within span bounds
- Implemented highlight state with thicker borders and increased opacity
- Set zOrder to 'bottom' to render rectangles behind candlesticks
- Completed Section 4 tasks (4.1-4.6) from span-annotation specification

- Verified ChartSelector uses theme-aware classes
- Tested full workflow: upload, chart creation, switching, annotation scoping
- Verified migration creates default chart with existing data
- Tested chart deletion with cascade delete of candles/annotations
- Tested edge cases: duplicate filenames, deleting last chart, upload with no charts
- Build passes with no type errors
- Add activeChartId/charts state to page.tsx with chart fetching on mount
- ChartSelector integrated in sidebar between header and file upload
- CandleChart and SvgOverlay fetch data scoped by activeChartId
- FileUpload returns chart info, auto-selects new chart after upload
- Annotation create/delete flows include chart_id
- Export scoped by activeChartId
- Toolbox receives activeChartId prop
- GET /api/candles accepts ?chartId= with fallback to most recent chart
- GET /api/annotations accepts ?chartId= with fallback to most recent chart
- POST /api/annotations now requires chart_id in request body
- GET /api/export accepts ?chartId= to scope exported annotations
- DELETE /api/annotations supports optional chartId scoping
- POST /api/upload now creates a chart named from the CSV filename
- Duplicate names get numeric suffix (e.g., btc-daily-2)
- Candles inserted with chart_id instead of replacing all data
- Response includes chart id and name
- Add charts table with id, name (unique), created_at
- Add chart_id FK to candles table with composite unique on (chart_id, time)
- Add chart_id FK to annotations table
- Custom migration handles existing data: creates 'Imported Data' chart and backfills chart_id
- Recreates tables for NOT NULL constraint (SQLite limitation)
- Change bullish candles to white interior with black outline
- Change bearish candles to solid black
- Update all wick colors to black
- Enable borders for candlesticks
Technical decisions with rationale:
- Label selection: parallel state to avoid disturbing line logic
- Label list UI: collapsible section in Toolbox with search/filter
- API design: extend DELETE with query params for bulk operations
- Docker: standalone output with multi-stage build
- Theme: CSS variables + Tailwind extension strategy
- Feedback: Toast component with terminal formatting
Includes risk mitigation, migration plan, and testing checklist
Line deletion via Delete tool already exists in current implementation.
Focus on three new capabilities: label-management, docker-deployment, hacker-theme
- Set up Next.js with App Router, TypeScript, Tailwind CSS
- Configure shadcn/ui with dark theme
- Install dependencies: lightweight-charts, papaparse, lucide-react
- Set up Drizzle ORM with better-sqlite3
- Create database schema for candles and annotations tables
- Generate migration SQL
