Dynamic logic conditions checked against the saved state of a record. The logic is not applied while editing a record without saving.

• Is not applied when a record is created.
• Applied in both the frontend and the backend.
• Applied in mass-update.

Use-case: Make a field Resolution read-only when Status = Completed. It won't be possible to write the Resolution field while the Status is saved as Completed. Even if we change the Status on the form, the Resolution field will still be read-only. But if we manage to change and save the Status, it will be possible to write the Resolution field .
