Can't Scrape all Results

I tried to scrape the results by setting the depth parameter to the maximum value, but it had no effect and most of the results were not scraped.

Start by tracing how the depth parameter is parsed and used in the scraper, then reproduce the report with depth set to its maximum value. The issue names no files or tests, so identify the relevant entry point and existing coverage first. Done means the maximum depth produces all expected results, with a regression test for the behavior.
