How a corpus becomes live

  1. 1RawThe record as published
  2. 2ResolvedEvery reference tied to the text it cites
  3. 3JudgedThe decisions the record already holds
  4. 4TunedRetrieval trained on them, eval attached

The method explains each step; the methodology sets the bar a number clears before it appears here. Once a corpus is live, the people who search it keep it correct: an accepted report through the MCP Feedback program goes into the next build.
