## Overview

TaskFlow is a PHP/SQLite group task tracker. Users sign in, view group-scoped dashboard summaries, find or create tasks, and open a task to update their group’s progress; status changes are recorded as history. Admins also manage accounts, roles, groups, and memberships. The graph separates page-level workflows, shared authentication/access helpers, and persistence. Relationships are grounded in the excerpts or README; the database schema and some documented capabilities are not independently inspected.

Main entry points: [`config.php`](https://github.com/priandoyo/taskflow/blob/main/config.php) (SQLite data store), [`functions.php`](https://github.com/priandoyo/taskflow/blob/main/functions.php) (Auth and access helpers), [`tasks.php`](https://github.com/priandoyo/taskflow/blob/main/tasks.php) (Task listing and editing), [`index.php`](https://github.com/priandoyo/taskflow/blob/main/index.php) (Sign-in)
