Design Summary: Task Tracker POC

This is an example design summary for a small local-only POC. It is intentionally short; real features should use the full docs/designs/<feature>/ Worker Gate packet.

Architecture

UI or CLI boundary
  -> task service
    -> typed task model
      -> in-memory task store for POC only

Components

Component Responsibility Handoff Note
Task boundary Accepts create/list/complete requests Keep thin; no business rules here
Task service Owns create, sort, complete behavior Unit test this first
Task model Typed fields: id, title, owner, due date, status Replace raw dicts before handoff
In-memory store Demo-only state Replace with persistence before production

Data Flow

  1. User submits a synthetic task.
  2. Boundary parses input into a typed task request.
  3. Service validates title, owner, and due date.
  4. Store saves the task in memory.
  5. Open-task view sorts incomplete tasks by due date.
  6. Completing a task changes status and removes it from the open-task view.

Security Boundary

  • Localhost only.
  • Synthetic data only.
  • No auth, no payments, no external APIs, no public tunnel.
  • No production/customer data.

Tests

  • Unit: create task validates required fields.
  • Unit: open tasks sort by due date.
  • Unit: completed tasks are hidden from open list.
  • Smoke: create task, list open tasks, complete task, confirm it disappears.

Known Non-Goals

  • Persistent storage.
  • Multi-user permissions.
  • Notifications.
  • Public deployment.
  • Analytics.
