Collaboration

Collaboration

Collaboration is designed for clear ownership and intentional sharing—not for broadcasting every personal task by default.

Roles in plain language

Role	What it means
Owner	Controls the list, sharing, and collaboration boundary.
Editor	Can contribute to authorized shared work.
Viewer	Can see shared work without editing authority.

The database enforces access with authorization predicates and Row Level Security. Interface controls explain permissions, but the database—not a button—is the security boundary.

Sharing safely

1. Share only the list relevant to the collaboration.
2. Confirm the invited person’s account and intended role.
3. Use activity and shared-work views to understand what changed.
4. Revoke access when the collaboration ends.

Dependencies represent real prerequisites and can prevent premature completion. Attachments stay private to authorized collaborators; do not use them to share secrets.

Read Task dependencies and Task attachments for the complete model.
