# Tasks: Hierarchical Async Task System for lit-html

## Relevant Files

- `src/task-system/types.ts` - Complete TypeScript interfaces and types for the task system 
- `src/task-system/Task.ts` - Core Task class with lifecycle management, hierarchy, and event handling
- `src/task-system/Task.test.ts` - Comprehensive unit tests for Task class
- `src/task-system/TaskManager.ts` - Core task orchestration with dependency tracking, resolution, and priority scheduling
- `src/task-system/TaskManager.test.ts` - Comprehensive unit tests for TaskManager with dependency scenarios
- `src/task-system/TaskRegistry.ts` - Global registry with automatic cleanup, memory management, and monitoring
- `src/task-system/TaskRegistry.test.ts` - Comprehensive unit tests for TaskRegistry covering all cleanup scenarios
- `src/task-system/index.ts` - Public API exports with convenience functions for common task patterns
- `src/integrations/lit-html-task-mixin.ts` - Lit-html component integration mixin
- `src/integrations/lit-html-task-mixin.test.ts` - Unit tests for lit-html integration
- `src/utils/task-debug.ts` - Developer debugging utilities and task graph visualization
- `src/utils/task-debug.test.ts` - Unit tests for debugging utilities

### Notes

- Unit tests should be placed alongside the code files they are testing
- Use `npx tsx` to execute TypeScript files for testing
- The system should be domain-agnostic and reusable across different use cases

## Tasks
