Core Features

• Task management across multiple workstations
• Task dependency workflow (depends_on)
• Role-based access (manager / operator / admin)
• Blockchain-like event logging (hash + prev_hash)
• Chain integrity verification

---

How it works

• Tasks are created under a project
• Assigned to machines (workstations)
• Executed in sequence
• Each action is recorded as a block
• Chain integrity can be verified

---

Blockchain logic

Each important event is stored as a block:

• TASK_CREATED
• TASK_STATUS_CHANGED
• TASK_PRIORITY_CHANGED
• TASK_MACHINE_CHANGED
• TASK_REORDERED

Each block contains:

• hash
• prev_hash

This ensures:

• data integrity
• tamper detection

---

Technologies

• Python
• Django
• SQLite
• HTML / CSS
