The knowledge a sector runs on is scattered across the whole internet. It is public, and it is still hard to know about, hard to reach, and hard to hold together in one place. Anyone who needs the whole picture assembles it by hand, and it goes stale the week after they finish.
Identify the public sources, crawl and corroborate them, build the front door, and keep crawling so the front door stays true.
Each step in the order it runs, and where one stops before the next begins.
One navigable public reference for the sector, built out of sources that were only ever scattered, and answering for what is true this week rather than last quarter.
