What indicators or conditions do you consider as the completion of a task in a project?

I consider a task in a project completed when the following conditions are met:

• All requirements from the technical specifications are implemented and tested.
• The code is covered by unit tests, and they pass without errors.
• Code review has been conducted, and all comments have been addressed.
• The functionality is integrated into the main branch of the project without conflicts.
• Documentation has been updated (if required).
• The task has been verified against acceptance testing criteria.

Only after fulfilling these points can the task be considered fully closed.
