Digital features are often managed using numeric prefixes (e.g., 000_Preparation.feature , 999_Completion.feature ) to set the order of execution.

Here is what generally happens with this type of file ID in a technical context:

Фиче-файл - Материалы по тестированию в 1С

did you see this ID (e.g., in a terminal, a GitHub issue, a specific software platform)? What kind of software or application is this for?
