"Problem Management": "A problem task is a task that is created to perform a piece of work that is required to complete a problem." This documentation explicitly defines the relationship where problem tasks are created to complete a problem. See the "Problem tasks" section within the Problem Management documentation for the Rome

2. ServiceNow Product Documentation
"Create a problem task": The procedure for creating a problem task involves navigating to an existing problem record and adding a new problem task from the 'Problem Tasks' related list. This workflow demonstrates the direct parent-child relationship. See the "Create a problem task" procedure in the Problem Management documentation.
3. ServiceNow Developer Documentation
"Table: Problem Task [problemtask]": The schema for the problemtask table shows a column named problem which is a direct reference to the problem table. This database-level reference establishes the parent-child link. This can be verified by navigating to System Definition > Tables and viewing the columns for the problemtask table in a ServiceNow instance.
