Checkpoint: Phase 19: Complete Task Management System Implementation

COMPLETED FEATURES:

1. Database Schema (drizzle/schema.ts)
   - Added tasks table with 14 columns
   - Status enum: pending, in_progress, completed, failed, blocked
   - Priority enum: low, medium, high, critical
   - Supports task dependencies, metadata, error tracking
   - Indexed by agentId, status, conversationId

2. Query Helpers (server/db.ts)
   - createTask() - create new task
   - getAgentTasks() - get all agent tasks
   - getConversationTasks() - get conversation tasks
   - getTaskById() - get single task
   - updateTask() - update task status/results
   - deleteTask() - delete task
   - getPendingAgentTasks() - get active tasks with priority sorting

3. tRPC Endpoints (server/routers.ts)
   - tasks.create - create task with validation
   - tasks.listByAgent - list agent tasks
   - tasks.listByConversation - list conversation tasks
   - tasks.get - get single task
   - tasks.update - update task with partial updates
   - tasks.delete - delete task
   - tasks.getPending - get pending tasks

4. React Component (client/src/components/TasksPanel.tsx)
   - Right sidebar panel for task display
   - Checkbox for task completion
   - Status badges (pending, in_progress, completed, failed, blocked)
   - Priority indicators (low, medium, high, critical)
   - Expandable task details (description, result, errors, timestamps)
   - Real-time updates via tRPC mutations
   - Delete button with confirmation

5. Chat Integration (client/src/pages/Chat.tsx)
   - TasksPanel integrated as right sidebar
   - Unique conversationId per chat session
   - Tasks panel width: 320px (w-80)
   - Responsive layout with flex container

6. Auto-Task Creation (server/orchestrator.ts)
   - autoCreateTasks() - create tasks for missing components
   - detectMissingComponents() - parse error messages for missing items
   - trackTaskCompletion() - update task status after execution
   - Supports: tools, skills, agents, components, dependencies

7. Unit Tests (server/tasks.test.ts)
   - 5 test suites covering all operations
   - 107 tests pass, 1 fails (due to missing DB table)
   - Tests cover: create, read, update, delete operations

NEXT STEPS:
1. Run pnpm db:push on production to create tasks table
2. Commit to Gitea with all changes
3. Deploy to production
4. Verify all tests pass on production DB
