Access to saved reports in Library via API

The original needs is to identify the linked project for a given task on current timesheets. The API endpoint for timesheets (logged-time-entries/v1) does not include the linked project for the task.

We are pulling data out of LP for our data warehouse and need to be able to link the 'worked tasks' with the appropriate project for the task.

I see four approaches -

Walk the tree and store the entire structure of LP externally to LP.

Walk the tree from the top for every Timesheet entry to hunt for the appropriate task

Use the Task Table report to provide a reference-able lookup matching tasks to their projects

Tempo update the API endpoint for logged-time-entries to include the parent project or perhaps the full lineage to the task.

Options one and two are time & API intensive

Option two doesn't appear to be accessible via API

Option three requires a change from Tempo/LP for the existing API.
