Phase 1: Core Auto-Scheduling Engine

[positonic]

Overview

Implement Motion-like task auto-scheduling with AI-powered slot finding, ETA tracking, and task chunking.

Features

• Auto-scheduling fields on Action model
• ETA tracking fields
• Task chunking fields
• TaskSchedule model for custom work schedules
• RecurringTask model foundation
• Task dependencies
• AutoSchedulingService with core algorithm
• ETA badge on task cards
• Task form UI with auto-scheduling toggles

API Endpoints

• scheduling.autoScheduleTask - Schedule a single task
• scheduling.rescheduleAll - Re-run scheduling for all tasks
• scheduling.calculateETA - Calculate days ahead/behind
• scheduling.updateAllETAs - Batch update ETAs
• scheduling.checkDeadlineConflicts - Detect at-risk tasks
• taskSchedule.* - CRUD for custom schedules

✅ Implementation Complete

Phase 1 has been fully implemented with the following changes:

Database Schema

• Added auto-scheduling fields to Action model
• Created TaskSchedule model for custom work schedules
• Created RecurringTask model (foundation for Phase 2)
• Added task dependency fields (blockedByIds, blockingIds)

Backend

• AutoSchedulingService (src/server/services/AutoSchedulingService.ts)

  • ETA calculation algorithm
  • Task scheduling with calendar integration
  • Chunk splitting for long tasks
  • Priority-based scheduling order

• Scheduling Router (src/server/api/routers/scheduling.ts)

  • autoScheduleTask - Schedule a single task
  • rescheduleAll - Re-run scheduling for all tasks
  • calculateETA - Calculate days ahead/behind
  • updateAllETAs - Batch update ETAs
  • checkDeadlineConflicts - Detect at-risk tasks

• TaskSchedule Router (src/server/api/routers/taskSchedule.ts)

  • Full CRUD for custom schedules

Frontend

• ETA Badge in ActionItem.tsx - Shows "X days ahead", "at risk", or "overdue"
• Task Form in ActionModalForm.tsx - Auto-schedule toggle, hard deadline option, schedule selector
